Yes, most North Shore remodels need a building permit. If your kitchen, bathroom, basement, or whole-home project changes walls, plumbing, wiring, HVAC, structure, or the exterior, you should expect one. Cosmetic work like painting or new flooring is often exempt, but the exact exemption list changes from one village to the next.
That is why a kitchen remodel in Winnetka and the same kitchen in Evanston can have very different permit costs and review times! One municipality charges a flat percentage of construction cost, another charges per $1,000 of job value, and a third may send your project to a design or preservation board.
At Delta Remodels, permit coordination is included in every design-build project, and we have completed 500+ remodels across the North Shore since 1987. Below, we explain what needs a permit, how each village calculates fees, and how long you should plan for, community by community.
This guide covers Lake Forest, Lake Bluff, Highland Park, Deerfield, Northbrook, Glenview, Northfield, Glencoe, Winnetka, Kenilworth, Wilmette, and Evanston.
Note: Fee schedules and rules change often. Use the numbers below for planning, not as a final permit quote, and always confirm with the building department before you apply.
Key Takeaways
- Illinois now has a statewide minimum building code, but your city or village still issues the permit, sets the fees, and does the inspections.
- Work behind the wall, such as plumbing, wiring, HVAC, or structural changes, almost always needs a permit. Painting and flooring usually do not.
- Building permit fees on the North Shore range from about 1.5% to 3.5% of construction cost, and trade, review, and deposit charges are often separate.
- Published review times run from about 5 working days in Kenilworth to 4 to 6 weeks in Evanston. Several villages do not publish a fixed timeline at all.
- A complete, accurate application is the biggest factor in getting your permit on time.
Do I Need a Permit for a Home Remodel on Chicago's North Shore?
If your remodel changes the structure of the house or one of its building systems, you need a permit. Below are the details for the most common remodeling work:
| Remodeling work | Permit likely? | Why |
|---|---|---|
| Removing or adding a wall | Yes | Structural and building code review |
| Removing a load-bearing wall | Yes | Structural plans normally required |
| Widening a doorway | Usually | May affect framing or headers |
| Kitchen layout changes | Usually | Plumbing, electrical, or walls change |
| Moving a sink, toilet, or shower | Yes | Plumbing supply and drain lines change |
| Adding electrical circuits | Yes | Electrical permit and review |
| Electrical panel upgrade | Yes | Electrical service work |
| New recessed lighting with new wiring | Usually | New electrical work |
| New or relocated HVAC ducts | Yes | Mechanical work |
| Finishing a basement | Usually | Building, electrical, plumbing, or mechanical work |
| Adding a bathroom | Yes | Multiple trades involved |
| Home addition | Yes | Building, zoning, and often engineering review |
| New deck or porch | Yes | Structural and zoning review |
| Changing a window or door opening | Usually | Framing and exterior review may apply |
| Exterior changes | Often | Building, zoning, or architectural review may apply |
The details matter. Winnetka, for example, requires a remodeling permit for new or removed walls, replacing 100 square feet or more of drywall or plaster, new electrical circuits, plumbing line changes, and mechanical ductwork. But it does not require a plumbing permit just to replace an existing fixture on the same supply and drain lines.
If you are planning a kitchen remodel, a bathroom remodel, or a basement remodel, you should assume a permit is part of the job.
What Remodeling Work May Not Need a Permit?
Purely cosmetic work is the most common exception. This usually includes interior painting, some flooring, carpet, minor drywall repair, cabinet replacement without plumbing or electrical changes, and like-for-like fixture swaps in some municipalities.
But you must not assume one village's exemption list applies in another:
- Northbrook lists painting, residential drywall repair, floor coverings, and like-for-like plumbing and electrical fixture replacement as work that does not need a permit.
- Wilmette exempts flooring and, for single-family homes, replacement windows or doors when the opening does not change.
- Evanston exempts paint, wallpaper, tile, carpet and similar finishes, detached sheds and playhouses up to 120 square feet, minor electrical, HVAC, and plumbing repairs, and window or door replacements that keep the same opening.
- Lake Forest allows a no-fee permit for certain maintenance work costing $1,000 or less, including drywall patching, same-opening door or window sash replacement, and countertop replacement without plumbing changes.
So the safest rule is simple: if the work goes behind the wall, changes a building system, changes an opening, or changes the structure, check the permit requirement before demolition starts. If you are still deciding how far to take your project, our guide on cosmetic refresh vs. full gut remodels explains where the permit line usually falls.
Is There One Illinois Remodeling Permit for Every North Shore Village?
No. Illinois changed its rules recently, but it did not create one statewide remodeling permit.
On January 1, 2025, Public Act 103-0510 set a statewide building code baseline under the Illinois Capital Development Board, requiring local codes to be at least as strict as the 2018, 2021, or 2024 ICC model codes. However, permit processes, fees, and review times are still run by local building departments, and homeowners do not deal with any state permitting office. The Illinois Energy Conservation Code, Illinois Accessibility Code, and Illinois Plumbing Code also continue to apply statewide, and starting January 1, 2027, building inspectors in Illinois must hold ICC certification.
Therefore, your village or city still controls:
- Permit applications and required drawings
- Local code amendments and zoning
- Permit fees and deposits
- Plan review procedures
- Contractor registration or licensing
- Inspections
- Historic preservation and architectural review
- Engineering and drainage review
Note: Some communities have also adopted the Illinois Stretch Energy Code, which is stricter than the standard energy code. Private homes only fall under it where the municipality has formally adopted it. Evanston did, and permit applications filed there after October 1, 2025 must comply.
So an "Illinois average permit cost" is not very useful for a North Shore remodel. Your address matters more.
How Much Does a Remodeling Permit Cost on the North Shore?
There is no single North Shore permit price. Each municipality calculates the building permit in its own way, using one or more of these methods:
- A percentage of construction cost
- A charge per $1,000 of construction value
- Altered square footage
- A fixed fee for a specific permit type
- A combination of permit, plan review, and inspection charges
Not only this, but the building permit is not always the whole bill. Your project may also carry separate charges for plumbing, electrical, HVAC, plan review, engineering, grading, stormwater, tree protection, right-of-way work, historic or architectural review, re-inspections, contractor licensing, and refundable deposits.
We have created a detailed table for you to compare the published fee structures and review times across the North Shore:
North Shore Remodeling Permit Cost and Timeline by Municipality
| Community | Published building/remodel fee basis | Published review timing | Important local detail |

What Would the Building Permit Cost on an $80,000 Kitchen?
To make this practical, below is the building permit portion only for an $80,000 kitchen remodel, using each municipality's published structure:
| Community | Estimated building permit portion |
|---|---|
| Northfield (2024 guide) | About $1,166 |
| Lake Forest | About $1,200 |
| Deerfield | About $1,520 |
| Evanston | About $1,600, plus $90 plan review |
| Wilmette | About $1,613, plus $79 plan review |
| Winnetka | About $2,400 |
| Kenilworth | About $2,400, plus plan review |
| Lake Bluff | About $2,400 |
| Glencoe | About $2,800, plus deposit |
Note: These are permit structures, not all-in totals. Trade permits, inspections, deposits, and engineering can add to the final municipal cost. For the construction side of the budget, see our North Shore kitchen remodel cost guide.
What Are the Remodeling Permit Rules in Each North Shore Community?
Below are the details for each community, including the local rules that most often surprise homeowners.
Lake Forest Remodeling Permits
Lake Forest requires a permit before construction, alteration, repair, or removal of a building or structure. Applications generally need architectural and plot plans, although the Community Development Director can accept a written description for simple work.
The FY2026 fee schedule uses a tiered structure: 1.5% of construction cost up to $100,000, 2% from $100,001 to $200,000, $4,000 plus 1% over $200,000 up to $500,000, and $7,000 plus 0.5% over $500,000. Plumbing, electrical, and HVAC charges can be separate.
But the bigger issue in Lake Forest is design review. The Building Review Board, formed in 1962 with seven resident members, reviews demolitions, additions, exterior alterations, and building scale variances outside the historic districts. Inside the historic districts and for designated landmarks, the Historic Preservation Commission reviews that work instead.
You must know how Lake Forest defines demolition. Removing all or part of an exterior wall, foundation, or roof counts, and so does a major change to the front facade or adding a second floor. So a rear addition can trigger board review even when most of the house stays. Board approvals also expire after two years unless a building permit is issued and paid within that time.
We are based in Lake Forest, and many of our projects here involve older homes. You can see one example in our Lake Forest walnut kitchen with a butler's pantry. Learn more about our Lake Forest remodeling services.
Lake Bluff Remodeling Permits
Lake Bluff requires permits for remodeling and other improvements. For a residential remodel, the Village asks for the application, drawings or a detailed scope, contractor information, and other project documents. Contractors generally need a Lake Bluff contractor license.
The general construction permit is $30 per $1,000 of construction cost, which equals 3%. Plumbing, electrical, and HVAC are listed separately, generally with a $25 application fee plus $10 per $1,000 of that trade's cost.
There is one rule every homeowner planning a large remodel must know. Fire sprinklers are required in the addition and the existing house once the total project reaches 75% of the finished home, measured by the village's floor area ratio calculation. That can change your budget completely! Projects over 2,000 square feet of combined addition and remodeling also need a construction debris recycling plan.
The Village strongly recommends a pre-application meeting for additions and larger decks before full plans are drawn. Lake Bluff also receives plan review services from the City of Lake Forest for certain projects under an intergovernmental agreement.
Does HOA approval replace a Lake Bluff permit? No. Some subdivisions require HOA approval in addition to the Village permit, and the Village lists HOA approval as a submission item where it applies.
See our Lake Bluff bathroom remodel with a freestanding tub or visit our Lake Bluff remodeling page.
Highland Park Remodeling Permits
Highland Park takes permit applications, drawings, and licenses through its online Civic Access Portal. Interior remodels involving structural, plumbing, electrical, or mechanical changes should be treated as permit work.
The City does not publish one fixed review time. Each submission gets its own estimated review time, and simple items like a water heater may be issued over the counter while other projects need several departments. Projects on state roads may also need an IDOT permit before the City issues its own.
The bigger planning issue is usually not the building permit itself. The Building Division works with Engineering on drainage, grading, and steep-slope compliance, so homes near a ravine or the bluff should expect engineering questions. Highland Park also has more than 130 local landmarks, and its Historic Preservation Commission reviews exterior changes to landmarks and contributing homes in historic districts.
For budgeting, do not rely on an old online calculator or an old contractor blog. Check the current City fee schedule against your final construction value. Learn more about our Highland Park remodeling services.
Deerfield Remodeling Permits
For 2026, Deerfield raised the construction permit fee for projects other than new single-family and two-family homes to $19 per $1,000 of estimated construction cost. Electrical, inspections, plan review, tree protection, and engineering fees can still apply.
Deerfield does not publish a fixed review time. Applicants receive an approximate review time at submission, and it changes with project size, the time of year, and whether Engineering also needs to review the plans. The Village's updated model codes took effect March 1, 2026, so drawings prepared earlier may need updates.
Good news for most homeowners: the Appearance Review Commission only covers the Village Center and the C-2 commercial district, so most houses skip design review. Visit our Deerfield remodeling page.
Northbrook Remodeling Permits
Northbrook draws a clear line between cosmetic work and permit work. Painting, drywall repair, carpet, tile, laminate flooring, like-for-like fixture replacement, residential siding, and certain small prefabricated sheds do not need a building permit. Zoning rules can still apply even when a permit does not.
The Village publishes practical review targets. Kitchens, baths, basements, and other small projects are reviewed in up to 10 business days, additions and large single-family remodels in up to 15, and resubmittals in about 10. Issued permits stay valid for 18 months.
Those targets describe the Village's review time only. If your designer takes two weeks to revise plans, your total permit time becomes longer.
Note: Northbrook's new $600 flat fee plus 1.4% of construction cost, starting July 1, 2026, applies to multi-unit residential and non-residential projects. It does not apply to single-family homes.
See our Northbrook bathroom remodel with honey oak and matte black or our Northbrook remodeling page.
Glenview Remodeling Permits
Glenview sends permit plans to every division that applies, which can include Building and Zoning, Engineering, Health, and Fire. The Village says review comments usually come back within about 10 business days, and more complex projects and additions follow a longer path.
Glenview is also the only village on this list that rewards off-season planning. For applications filed between December 1 and February 28, the Village gives a 25% discount on building and plan review fees for single-family home improvements, including additions, interior remodels, garages, and decks. The discount does not apply to new homes or to pass-through charges like water service engineering.
So if you are planning a spring kitchen, filing in winter can save you money. You can see our Glenview kitchen with a marble island and brass pendants or visit our Glenview remodeling page.
Northfield Remodeling Permits
Northfield asks for a broader submission package than many homeowners expect. For additions and remodels, the Village lists the building permit application along with electrical, HVAC, plumbing, roofing, and tree preservation forms, plus a floor area ratio worksheet where it applies.
General contractors do not need Village registration, and electrical and HVAC licenses from qualifying municipalities are accepted.
The Home Improvement Guide linked by the Village lists $60 for the first $1,000 and $14 for each additional $1,000, plus plan review and escrow. Because that guide is dated July 2024, you must confirm the current amounts before using them in a signed budget. Northfield also added a 2.95% surcharge on permit, bond, and escrow payments made by credit card starting September 5, 2025. Visit our Northfield remodeling page.
Glencoe Remodeling Permits
Glencoe requires a permit before covered construction, alteration, repair, or excavation begins, and it directs applicants to its current Comprehensive Fee and Fine Schedule.
The Village's building permit application states that, unless a project type is listed separately, fees are 3.5% of total construction cost including materials and labor, and a refundable inspection deposit is also required. So a $100,000 kitchen means about $3,500 in building permit fees before the deposit. Any addition or remodel with plumbing work also needs a cross connection inspection form.
Construction value matters a lot here. Glencoe's code allows the Village to ask for proof of the actual value of completed work. If the final value is higher than what was reported, the permit can be adjusted, and if it exceeds the estimate by more than 25%, an additional charge can apply. In other words, lowering the contract value on the application is not a smart way to save on permit fees.
Historic properties need extra attention. Glencoe requires a building permit for changes to designated exterior features of landmarks or properties in certified historic districts. Learn more about our Glencoe remodeling services.
Winnetka Remodeling Permits
Winnetka has one of the clearest remodeling permit descriptions on the North Shore. A remodeling permit is required for new or removed walls, replacing 100 square feet or more of drywall or plaster, new electrical circuits, extended electrical service, hardwired devices, plumbing waste, drain, vent, or supply changes, and mechanical ductwork.
Winnetka also requires permits for additions of any size, basement finishes, decks, roof replacement, and impermeable surfaces. It even requires a permit for a new or replacement furnace or air conditioner.
The remodeling fee is $30 per $1,000 of construction cost with a $100 minimum, plus trade fees. For timing, the Village lists interior remodels at 2 to 3 weeks, new homes and additions at about 3 weeks for the first review, and each revision at another 7 to 10 business days.
That is why changing a structural layout after the plans reach the Village can push your start date more than you expect. Winnetka's floor area limits also make basements a common way to add living space, which our basement remodel cost guide covers in detail. Visit our Winnetka remodeling page.
Kenilworth Remodeling Permits
Kenilworth publishes unusually clear numbers for interior remodeling. The permit package can include the application, a detailed contractor proposal or scope, construction cost, architectural plans, a plat of survey, and site or tree information when relevant.
Below are the published costs:
- Permit fee: 3% of construction cost, $30 minimum
- Typical plan review: about $50 to $250
- Significant project review: $700+
- Typical refundable escrow: 25% of project value, up to $2,500
- Major project or right-of-way escrow: $5,000
Initial review takes 5 to 10 working days, and later reviews take about 5 working days. Administrative processing is separate.
Contractors do not need to register with the Village, but electrical, plumbing, and roofing licenses must be submitted with the application. If you are considering a teardown, you must also know that Kenilworth's Building Review Commission can delay a demolition permit for up to a year when a home has historical or architectural significance. The Village also encourages pre-application meetings for additions, basement expansions, and hardscape changes. Visit our Kenilworth remodeling page.
Wilmette Remodeling Permits
Wilmette requires permits for remodeling, plumbing, electrical, HVAC, additions, roofing, and many other residential improvements.
This is one of Wilmette's most important differences: projects with structural work, or with a construction cost above $25,000, need drawings stamped by an Illinois registered architect or structural engineer. Reviewers can also ask for stamped plans on smaller jobs that are complex, and the Village specifically names kitchens, baths, new window openings, and basements. Wilmette also only accepts a boundary survey, so a mortgage-style plat will be sent back.
The base building permit fee is $20.16 per $1,000 of estimated job value, the residential remodeling plan review fee is $79, and each inspection or re-inspection costs $39. For most projects, the Village aims for 10 business days for each reviewer to complete the first review. That is a target, not a promise that your permit will be in hand ten days later.
Plan for the permit window too. Most residential permits in Wilmette last 12 months, and each 30 days past expiration costs 1/12 of the original fee. Visit our Wilmette remodeling page.
Evanston Remodeling Permits
Evanston requires a permit for most non-cosmetic construction, even when the homeowner does the work personally. The 2026 building permit base fee is 2% of construction cost, and a contractor proposal or contract must be provided before issuance to verify value.
Plan review is separate:
| Construction value | Plan review fee |
|---|---|
| Under $10,000 | $25 |
| $10,000 to $49,999 | $50 |
| $50,000 to $99,999 | $90 |
| $100,000 to $149,999 | $150 |
| $150,000 to $199,999 | $200 |
Higher-value projects use percentage-based plan review, and trade permits and inspections add to the total.
Evanston publishes the longest standard timeline on the North Shore. Regular building permits take 4 to 6 weeks, express permits take 3 to 4 business days, and plan revisions take 10 to 15 business days. Plans must be submitted electronically, and each inspection or re-inspection costs $70.
Contractors must register with the City, and the current annual fee is $150 for a general contractor and $125 for a trade contractor. Not only this, but landmark homes and homes in historic districts must get a Certificate of Appropriateness before even express permit work like windows or roofing.
See our Evanston remodeling page, and if you are planning for aging in place, our accessible kitchen remodeling service is available across the North Shore.
Why Can the Same Remodel Cost More to Permit in One Village Than Another?
Because the building permit is only one part of the review system. Most people assume the village is the only factor; it is not entirely true. Scope matters just as much.
Imagine two homeowners each planning a $150,000 kitchen and first-floor renovation. One keeps the exterior the same and avoids structural changes. The other removes a load-bearing wall, enlarges windows, moves plumbing, upgrades the electrical service, modifies HVAC, and changes drainage.
The contract totals look similar. But the second project may need structural drawings, more review disciplines, more trade permits, and more inspections. So your address and your scope decide your permit cost together.
Why Do North Shore Permit Timelines Vary So Much?
Published review targets describe the government's review time, not the full calendar time from first submission to permit issuance. If the village reviews your plans in ten days and the architect takes twelve more days to answer corrections, that permit did not really take ten days.
A review can slow down because of:
- Incomplete plans or an incomplete contractor list
- Missing structural calculations
- A construction value that does not match the proposal
- Plumbing or electrical plans that do not match the floor plan
- An addition that breaks a setback or lot coverage limit
- Stormwater or grading review
- Historic or exterior design review
- Correction comments that require a redesign
Therefore, we always build the permit stage into the project schedule before we give a start date. For the construction side, see our kitchen remodel timeline and bathroom remodel timeline.
Which Offices and Boards Review a Remodel?
Most interior remodels only go through the building department. Larger or exterior projects can involve several offices. Below are the details:
| Office or board | What it reviews |
|---|---|
| Building department | Code compliance, plan review, and inspections |
| Zoning staff | Setbacks, floor area, lot coverage, and height |
| Engineering | Grading, drainage, stormwater, and right-of-way work |
| Fire department | Sprinklers and life safety on larger projects |
| Design or appearance review board | Exterior design where the village has one |
| Historic preservation commission | Landmarks and homes in historic districts |
| Zoning board of appeals | Variance requests |
Board calendars are often the longest part of the timeline. Lake Bluff's Architectural Board of Review, for example, meets on the first Tuesday of each month, so missing one submission deadline can cost you a full month.
What Regional Issues Can Add Review Time on the North Shore?
Historic and Architecturally Significant Homes
The North Shore has a large stock of older homes, and several communities regulate exterior changes to landmarks and historic districts. A normal interior bathroom remodel may never reach a preservation board. But replacing windows, changing a front elevation, or building an addition can be very different, especially in Lake Forest, Highland Park, Evanston, and Glencoe.
Ravines, Bluffs, Floodplain, and Drainage
A remodel that stays inside the house is simpler than an addition, patio, or driveway that adds hard surface. Homes near ravines and the bluff in Highland Park, Lake Forest, and Lake Bluff often get extra engineering review for grading, drainage, and slope stability.
Frost Depth and Older Houses
Our winters matter too. Footings in northern Illinois must reach 42 inches or more below grade, so every deck, porch, or addition foundation is checked for it. Similarly, many North Shore homes are 80 to 100 years old, and opening walls often uncovers old wiring or undersized water service that changes the permit scope mid-project.
Trees
Several North Shore villages regulate tree removal and protection during construction. Make sure to check protected trees before finalizing an addition footprint, driveway expansion, or construction access route.
Right-of-Way Work
Moving a water or sewer line, replacing a driveway apron, placing a dumpster on public property, or opening the street can create a separate permit or deposit outside the normal building permit.
Do I Need a Separate Plumbing, Electrical, or HVAC Permit?
Often, yes. A "building permit" does not always cover every trade. Depending on the village and the project, your permit package can include building, electrical, plumbing, mechanical, sewer, grading, right-of-way, tree, demolition, fire, and historic or architectural approval.
Evanston's fee schedule is a good example, with separate charges for building, electrical, mechanical, plumbing, water and sewer, planning, historic preservation, and public works. Lake Bluff also publishes separate construction, plumbing, electrical, and HVAC charges. So comparing only building permit fees between villages can underestimate your final municipal cost.
Do I Need an Architect or Structural Engineer for a Remodel?
Not for every remodel. A cosmetic kitchen update may not need a separate architect. But removing a load-bearing wall, altering beams, expanding an opening, or building an addition usually needs signed structural drawings or calculations.
Local rules can go further. Wilmette requires stamped plans for structural work or any project over $25,000, and reviewers can ask for them on smaller complex kitchens, baths, and basements.
That is why you must check permit requirements before the design is finished, not after the contract is signed. At Delta Remodels, our in-house designer, Katarzyna Pindral, coordinates design with any required architects or engineers, so the drawings match what the village expects.
How Can You Reduce Remodeling Permit Delays?
The best way is not to "push" the permit department. The best way is to submit a package that gives reviewers fewer reasons to send it back. Below are the steps we follow on every project:
- Confirm the exact permit category. A kitchen remodel, addition, and structural renovation may have different checklists.
- Match the drawings to the real scope. If the contract says a wall is coming out, the plans must show it.
- Show every affected trade. Plumbing, electrical, and HVAC changes should not appear for the first time after demolition.
- Solve structural questions first. Do not submit a plan showing a removed load-bearing wall with no structural solution.
- Check zoning before designing an addition. Setbacks, lot coverage, and floor area limits can force a redesign.
- Provide the correct construction value. Many villages use it to calculate fees, and some adjust the fee later.
- Check contractor licenses and registrations early. A permit can be approved and still wait on missing contractor documents.
- Ask for a pre-application meeting on bigger projects. Kenilworth and Lake Bluff both encourage them.
- Answer all correction comments together. Partial answers often create another review round.
- File in winter when it helps. In Glenview, filing between December and February saves 25% on fees.
A clean submission does not guarantee approval, but it removes most avoidable delays.
What Happens If You Remodel Without a Permit?
Starting first and asking later can get expensive. Possible consequences include a stop-work order, higher permit charges, re-inspection fees, opening finished walls so hidden work can be inspected, correcting work that does not meet code, and delayed completion.
Evanston's 2026 schedule increases the permit fee by 50% when work starts without the required permit, and Lake Forest's code also allows additional charges.
The hardest part is concealed work. Once drywall, tile, or cabinets cover plumbing, framing, or wiring, an inspector may not be able to verify it without tearing into finished construction. Not only that, but North Shore buyers' inspectors and attorneys regularly check permit history, so unpermitted kitchens and basements often come up when you sell.
Who Should Pull the Remodeling Permit, the Homeowner or the Contractor?
It depends on the municipality and the type of work. But for a full design-build remodel, we recommend that the team controlling the plans, construction, and inspections also handles the permit. That keeps one set of documents aligned from design through final inspection.
At Delta Remodels, we map permits and village requirements before construction and coordinate every inspection during the project. You should still receive and keep:
- The approved permit
- The approved plans and any approved revisions
- The inspection record
- Final inspection or occupancy documentation where it applies
What Is the Remodeling Permit Process?
For most North Shore remodels, the sequence looks like this:
- Define the scope. Walls, plumbing, electrical, HVAC, windows, exterior, structure, and drainage.
- Confirm the municipality. Do not use a neighboring village's rules just because the homes look similar.
- Check zoning and special restrictions. This matters most for additions, exterior work, historic homes, and hardscape.
- Prepare permit drawings. A simple remodel may need a floor plan and scope; a structural renovation may need architectural plans and engineering.
- Submit trade information. Electrical, plumbing, and mechanical documents may be part of the same application or separate permits.
- Village or city review. The reviewer approves the application or issues comments.
- Respond to corrections. Plans are revised and resubmitted if needed.
- Pay permit fees and deposits. Final fees are often calculated after review.
- Start construction. Work begins after the permit is issued, not after the application is submitted.
- Complete rough inspections. Framing, electrical, plumbing, and mechanical work are inspected before walls close.
- Complete final inspections. The permit stays open until final inspections and closeout are done.
We have broken our own process into clear steps from consultation to final walkthrough, and you can read how we price projects on our how estimates work page.
How Much Time Should You Add for Permits Before Construction?
For early planning, these published municipal figures are useful:
| Community | Published initial review time |
|---|---|
| Kenilworth (interior remodel) | 5 to 10 working days |
| Northbrook (kitchen, bath, basement) | Up to 10 business days |
| Glenview | Comments usually within about 10 business days |
| Wilmette | 10 business day goal per reviewer |
| Winnetka (interior remodel) | Typically 2 to 3 weeks |
| Evanston (regular permit) | 4 to 6 weeks |
But do not turn these numbers into a promised start date. A correction round, structural revision, zoning issue, or missing contractor document can add one week or several.
So the useful question is not "How long does the village take?" It is "How long will it take to prepare a complete application, get the first review, answer corrections, receive the permit, and schedule construction?" That is the timeline that matters to you.
Frequently Asked Questions About North Shore Remodeling and Permits
How much does a kitchen remodel cost on the North Shore?
Based on our current North Shore project data, a full kitchen remodel usually runs about $65,000 to $95,000, high-end kitchens about $100,000 to $180,000+, and larger luxury custom projects above $180,000. Some contracts include permit fees in the total and others list them separately, so compare proposals carefully. See our full kitchen remodel cost guide, and for bathrooms, our bathroom remodel cost guide.
What is included in a design-build estimate?
A detailed design-build estimate should list demolition, framing, mechanical, electrical, and plumbing work, finishes, allowances, permit assumptions, and the expected schedule. Our estimates also include permit and inspection notes for your specific village, so they are considered before construction starts. Learn more on our how estimates work page.
Do you offer financing?
We work with financing providers for qualified homeowners. Available programs and lender terms can change, so we confirm them during your consultation.
What is the difference between design-build and hiring a general contractor?
With design-build, design, scope, permit coordination, and construction are handled by one team as one connected project. With a traditional general contractor, you usually hire an architect or designer first and then send finished plans out for pricing. For permit-heavy remodels, the biggest benefit of design-build is that the construction team sees the plans before they are submitted and can flag buildability or village issues early.
Do I need an architect if I work with a design-build firm?
Not usually as a separate hire. A design-build company coordinates the required design professionals within the project. But the village still decides whether an architect or structural engineer stamp is legally required. Wilmette, for example, requires stamped plans for structural work or projects over $25,000.
Do I need a permit for my remodel?
Usually yes, if the project changes walls, structure, plumbing, wiring, HVAC, or the exterior. Purely cosmetic work may be exempt, but exemptions change by village, so you must check your specific village rules rather than a general Illinois list.
How long does a typical remodel take?
The permit is only one part of the schedule. Our current construction times are 8 to 16 weeks for kitchens, 3 to 6 weeks for bathrooms, and 8 to 16 weeks for basements. Design, selections, and permitting happen before that. Structural changes, special-order materials, and multi-room projects take longer.
How far in advance should I book a remodeling project?
Start planning well before the date you want demolition to begin. For a kitchen or bathroom with drawings and permit review, allow several weeks for design, selections, and village processing. For an addition or a project needing zoning, engineering, historic, or architectural review, planning several months ahead is more realistic.
Can I stay in my home during a remodel?
Often, yes, especially for a bathroom or a single-room project. A whole-home remodel, major kitchen project, long utility shutdown, or work on your only usable bathroom may make a short move-out more practical. We decide this from the actual phasing plan, not the room name alone.
How do you handle dust, noise, and daily disruption?
We plan for dust containment, floor protection, debris routes, working hours, temporary barriers, daily cleanup, utility interruptions, and access to the rooms you still use. North Shore villages also regulate construction hours and inspections, so our schedule accounts for both your routine and local rules. Our work is also backed by a 3-year workmanship warranty.
What areas do you serve?
We are based in Lake Forest and serve Chicago's North Shore and nearby suburbs, including every community in this guide. See the full list on our service areas page, including Highwood and Skokie.
Do you build ADUs or in-law suites?
An ADU or in-law suite must be checked for zoning before the floor plan is finalized. The review can involve permitted use, the number of dwelling units, a second kitchen, egress, fire separation, parking, plumbing, electrical service, and setbacks. Evanston specifically includes ADUs in its residential permit information. You must know that a room called an "in-law suite" on a plan does not automatically qualify as a legal second dwelling unit. Many of our clients create guest suites through basement remodeling or accessible bathroom design for aging parents.
How do I get started?
Start with four things: your address, the rooms you want to remodel, the major layout changes you are considering, and your target timing. From there, we check the permit path before the design goes too far. You can schedule a free in-home consultation or call us at (847) 847-4148. More answers are on our remodeling FAQ page.
Our Thoughts
There is no single North Shore permit rule. For an interior remodel, Kenilworth starts at 3% of construction cost with a 5 to 10 working day first review. Winnetka publishes 2 to 3 weeks. Wilmette may require stamped plans once your project passes $25,000. Evanston charges 2% and publishes a 4 to 6 week standard timeline. And in Lake Forest or Highland Park, a board review can matter more than the permit fee itself.
Scope matters just as much as your address. Moving plumbing, taking out a wall, enlarging a window, or changing the exterior can turn a simple renovation into a project with structural, engineering, zoning, or architectural review. Our recommendation is always to find this out before the construction schedule is promised and before demolition starts.
