Chicago Building Permits & Codes for Kitchen and Bathroom Remodeling 2026
Chicago Building Permits for Kitchen & Bathroom Remodeling — Quick Answer
Most kitchen and bathroom renovations in Chicago require building permits — specifically when the work involves structural changes, plumbing relocation, new electrical circuits, HVAC modifications, or significant fixture replacement. Permits are generally not required for cosmetic-only work like painting, flooring replacement, or swapping cabinetry without touching plumbing or electrical. Chicago follows the 2021 International Existing Building Code (IEBC) with local amendments, and permits must be active before any structural or systems work begins.
Chicago building permits for a typical kitchen or bathroom remodel cost $400–$2,500 depending on project valuation and scope. Standard Plan Review takes 7–9 weeks — which is why Assembly Squad submits permits on day one of every project, running them concurrently with design finalization so they never add to your total timeline. Permits are valid for 6 months from issuance, and work must begin within that window. See our kitchen-specific permit guide and our condo permit guide for deeper dives.
⚠️ Unpermitted Remodeling Work in Chicago — The Real Risks
Unpermitted kitchen or bathroom work in Chicago creates serious legal and financial exposure: failed home sale inspections, required demolition of completed work, city fines of $500–$10,000 per violation, and personal liability for any injury resulting from non-code construction. Chicago building inspectors actively flag unpermitted work during neighborhood inspections. Assembly Squad pulls permits on every project — no exceptions, no shortcuts.
When You Need a Permit for Chicago Kitchen and Bathroom Remodeling
Chicago's Department of Buildings requires permits for any work that affects the structural, plumbing, electrical, or mechanical systems of a home. Here is exactly when permits are and are not required:
✅ Permit Required — Kitchen Remodeling
- Moving or adding plumbing supply or drain lines — relocating a sink, adding a dishwasher stub-out, or moving the refrigerator water line all require a plumbing permit
- Adding new electrical circuits — kitchen remodels that add dedicated circuits for appliances (refrigerator, dishwasher, microwave, garbage disposal) require an electrical permit
- Removing or altering walls — opening a wall between kitchen and dining room, removing a soffit that contains structural elements, or any load-bearing wall work requires a building permit and structural engineering review
- Relocating gas lines — moving the gas connection for a range, adding a gas line for a new appliance, or upgrading gas supply requires a plumbing/gas permit and licensed gas contractor
- Adding or modifying range hood ventilation — new exterior exhaust penetrations and ductwork modifications require a mechanical permit
- Upgrading electrical panel or service — adding circuits often triggers a panel capacity review that requires an electrical permit
✅ Permit Required — Bathroom Remodeling
- Moving plumbing fixtures — relocating a toilet, moving a shower drain, changing tub position, or adding a second sink all require a plumbing permit
- Adding a bathroom — new bathrooms always require building, plumbing, and electrical permits; Chicago also requires mechanical permits for exhaust fans in new wet rooms
- Converting a tub to a walk-in shower — any change to the drain location or shower pan waterproofing system requires a plumbing permit
- Adding heated floors — electric radiant floor systems require an electrical permit for the new circuit and thermostat wiring
- Installing a steam shower — steam generators require dedicated electrical circuits (permit required) and plumbing connections (permit required)
- Structural changes — expanding a bathroom footprint, moving walls, or merging two smaller bathrooms into one primary suite requires a building permit
- Exhaust fan installation or upgrade — any new exterior penetration for bathroom exhaust requires a mechanical permit in Chicago
❌ No Permit Required — Cosmetic Work Only
- Painting and wallpaper — interior painting, wallcoverings, and decorative finishes require no permit
- Flooring replacement — replacing tile, hardwood, LVP, or carpet where no subfloor structural work is involved requires no permit
- Replacing cabinetry in the same location — swapping kitchen cabinets without moving plumbing or electrical requires no permit (though electrical work triggered during the swap does)
- Countertop replacement — replacing countertops without altering plumbing connections requires no permit
- Replacing fixtures in the same location — swapping a toilet, faucet, or showerhead to an identical configuration in the same location is a no-permit repair in Chicago
- Light fixture replacements — replacing existing fixtures on existing circuits requires no permit; adding circuits does
- In-kind porch or stair repairs — repairs using the same materials and same configuration as existing construction require no permit in Chicago

The Chicago Permit Process — Step by Step for Kitchen and Bathroom Remodeling
Chicago's permit process is predictable when managed correctly from day one. Assembly Squad handles every step in-house — homeowners never need to visit the Department of Buildings. Here is exactly how the process works:
Permit Application Preparation
Assembly Squad prepares the complete permit package: architectural drawings, structural engineering (if walls are involved), plumbing diagrams, electrical load calculations, and site plans. All documents are prepared to Chicago Department of Buildings specifications — missing any required document restarts the review clock.
Days 1–5 of your projectElectronic Submission via Chicago DOB Portal
Chicago now requires electronic permit submissions through the Chicago Department of Buildings' online portal. Assembly Squad submits all permits electronically on day one of the project — no in-person filings required. High-rise condo projects also require simultaneous HOA alteration agreement submission.
Day 1 of project — submitted immediatelyStandard Plan Review — 7–9 Weeks
Chicago's Standard Plan Review process takes 7–9 weeks from submission for kitchen and bathroom remodels involving structural or systems work. Assembly Squad monitors the submission status and responds immediately to any reviewer comments — comments that go unanswered reset the review clock. During this period, we finalize design selections, order materials, and produce cabinetry so construction begins the day permits are issued.
7–9 weeks running concurrently with designPermit Issuance and Posting
Once approved, permits are issued electronically and must be posted visibly at the job site before any permitted work begins. Chicago requires the permit card and approved plans to be accessible at the site at all times during construction. Assembly Squad prints and posts all permit documents on day one of construction.
Posted before construction beginsRough Inspections
Chicago requires inspections at rough-in stage — before walls are closed — for plumbing, electrical, and structural work. Assembly Squad schedules all rough inspections and has inspectors on-site during the appropriate construction phase. Rough inspections typically occur within 2–5 business days of scheduling.
Scheduled during construction, typically week 2–3Final Inspection and Permit Close
Final inspections are required before the project is considered code-compliant and permitted work is closed. Assembly Squad schedules final inspections and accompanies all inspectors through the completed project. Once the final inspection passes, the permit is closed and the homeowner receives a permanent code-compliant certificate of completion.

2026 Chicago Building Code Updates That Affect Kitchen and Bathroom Remodeling
Chicago adopted significant code updates effective 2025–2026 that directly impact kitchen and bathroom remodeling projects. Every Assembly Squad project is designed and built to current Chicago Municipal Code — not the outdated versions many contractors still use.
□ 2026 Chicago Building Code — Key Changes for Remodelers
- 2021 IEBC adoption: Chicago now enforces the 2021 International Existing Building Code with local Chicago amendments — replacing the previous 2012 code adoption. This affects how existing non-compliant conditions must be addressed when triggered by renovation scope.
- Energy code — 2021 IECC: Window and door replacements in kitchen and bathroom renovations must meet 2021 IECC energy performance standards. U-factor and SHGC requirements are stricter than prior code, affecting exterior window specifications.
- Arc fault circuit interrupters (AFCI): All kitchen and bedroom circuits must now include AFCI protection under the updated NEC adoption. This adds $150–$400 to most kitchen electrical scopes but is required on every new circuit.
- Bathroom exhaust ventilation: Updated mechanical code requires minimum 50 CFM continuous or 110 CFM intermittent exhaust for all bathrooms — with exterior discharge required. Recirculating exhaust fans no longer meet code for new or remodeled bathrooms in Chicago.
- Porch and exterior stair requirements: 2025 amendments tightened Chicago's porch construction requirements, including mandatory galvanized fasteners, maximum spacing on guardrail balusters, and stricter attachment details for porch ledgers. Affects any kitchen addition or bathroom addition projects.
- Lead paint disclosure: Chicago's amended EPA lead-safe renovation rules require contractor disclosure and certified lead-safe work practices in all homes built before 1978 — which encompasses the majority of Chicago's housing stock. Assembly Squad is EPA Lead-Safe Certified.
Condo and High-Rise Permit Requirements — Chicago 2026
Chicago condominium renovations have a two-track approval process: city building permits AND HOA alteration agreement approval. Both are required before any work begins — and the HOA process is often the longer of the two.
Building Department Permits
Same permit requirements as single-family homes — building, plumbing, electrical, and mechanical permits as applicable to scope. Chicago DOB does not differentiate between condo and house permits. Standard Plan Review takes 7–9 weeks from submission.
$400–$2,500 · 7–9 weeksAlteration Agreement
Required by every Chicago condo association before renovation work begins. Typically requires architectural drawings, proof of contractor licensing and insurance, a signed alteration agreement, neighbor notification, and elevator reservation. Assembly Squad has a 97% first-submission approval rate — we know exactly what each building's management requires.
$500–$2,000 · 2–6 weeksCertificate of Insurance
Chicago high-rise buildings require contractors to carry minimum $2M general liability and workers' compensation insurance, with the building named as additional insured. Assembly Squad carries $2M GL and full workers' comp — certificates are generated same-day for any Chicago building.
Included in Assembly Squad scopeBuilding Rules Compliance
Chicago high-rise buildings restrict work to weekdays 8am–5pm or 9am–5pm (building-specific), require elevator reservations for material deliveries, and may prohibit certain demo work (jackhammering, concrete cutting) entirely on weekdays. Assembly Squad builds all building restrictions into the project schedule from day one.
Adds 10–15% to labor costWhat Chicago Buildings Have the Strictest Permit and HOA Requirements
Not all Chicago buildings treat renovation approvals the same way. Here is what Assembly Squad encounters across the neighborhoods we work in most:
| Building Type / Neighborhood | HOA Approval Complexity | Typical Extra Requirements | Added Timeline |
|---|---|---|---|
| Lakeshore East high-rises | High | Board vote, neighbor notification, noise decibel limits | 4–6 weeks |
| Streeterville / Gold Coast towers | High | Alteration agreement, insurance cert, dedicated freight elevator | 3–5 weeks |
| River North full-amenity buildings | Medium–High | Resident manager approval, hours restrictions 9–5 only | 2–4 weeks |
| Lincoln Park 2–4 flats | Low–Medium | Often only city permits required; shared wall notification | 0–2 weeks |
| Wicker Park / Bucktown greystones | Low | City permits only; no HOA for most 2-flats | 0 weeks added |
| South Loop newer developments | Medium | Alteration agreement, insurance, work hour restrictions | 2–3 weeks |
| West Loop loft buildings | Medium | Freight elevator required; structural review for loft mezzanines | 2–4 weeks |
| Historic landmark buildings | Very High | Chicago Landmarks Commission review for exterior-facing work | 8–16 weeks additional |
❌ What Happens When Chicago Kitchen or Bathroom Work Is Done Without Permits
- Stop-work orders: Chicago building inspectors can issue stop-work orders on any active project where permitted work is occurring without a posted permit. All work stops immediately — including work by unaffected trades — until permits are obtained and inspections are passed.
- Mandatory demolition: Chicago code requires that unpermitted structural, plumbing, or electrical work be exposed for inspection — meaning finished walls, tile, and cabinetry must be removed to allow inspector access. The homeowner pays for both the demolition and the rebuild.
- City fines: Chicago Municipal Code Section 14A-1-105 authorizes fines of $500–$10,000 per violation per day for work performed without required permits. Multiple violations compound rapidly.
- Home sale complications: Chicago requires permit disclosure at point of sale. Unpermitted work flagged during buyer inspection either kills the sale or requires retroactive permits and remediation — often at costs exceeding the original project budget.
- Insurance voidance: Homeowner's insurance policies routinely include clauses voiding coverage for losses caused by unpermitted construction. A kitchen fire traced to unpermitted wiring can result in total coverage denial.
Chicago buyers and their agents now routinely require permit history verification before closing. A properly permitted kitchen or bathroom renovation is a documented asset — unpermitted work is a disclosed liability that buyers use to negotiate price reductions averaging 10–18% of the renovation value.

Chicago Building Permits for Kitchen and Bathroom Remodeling — FAQ
Yes — most kitchen remodels in Chicago require permits. Specifically, you need permits for any work involving structural changes (wall removal, opening up a floor plan), plumbing relocation (moving a sink, adding a dishwasher line), new electrical circuits (dedicated appliance circuits, under-cabinet lighting circuits), gas line modifications, or range hood exhaust penetrations. Cosmetic-only work — replacing cabinets in the same location without touching plumbing or electrical, swapping countertops, or replacing flooring — generally does not require a permit. Assembly Squad evaluates permit requirements on every project and pulls all required permits before construction begins.
Yes — most bathroom remodels in Chicago require permits. Permits are required for moving plumbing fixtures (toilet relocation, shower drain relocation), adding new circuits (heated floors, steam showers), converting a tub to a walk-in shower when the drain location changes, installing exhaust fans with new exterior penetrations, and any structural changes. Replacing a toilet in the same location, swapping a faucet, or refinishing a tub without any systems work typically does not require a permit. For full bathroom gut renovations, Assembly Squad pulls combined building, plumbing, electrical, and mechanical permits as a package — the total permit cost for a standard bathroom gut runs $400–$1,200 in Chicago.
Chicago's Standard Plan Review takes 7–9 weeks from submission for kitchen and bathroom remodels involving structural or systems work. Expedited review (at additional fee) reduces this to 2–3 weeks. Simple trade permits — plumbing-only or electrical-only without structural changes — can sometimes be issued in 1–3 weeks. Assembly Squad submits all permits electronically on day one of every project so the review period runs concurrently with design finalization and material selections — never adding to your total project timeline. Work must begin within 6 months of permit issuance and permits remain active for 6 months.
Chicago building permits for a kitchen or bathroom remodel cost $400–$2,500 depending on project valuation and scope. A standard bathroom gut with plumbing, electrical, and mechanical permits typically runs $400–$900. A full kitchen gut with structural work (wall removal), plumbing relocation, electrical upgrade, and mechanical permits typically runs $900–$2,500. Chicago calculates permit fees as a percentage of declared project value with minimum fees by permit type. Condo buildings add HOA alteration agreement fees of $500–$2,000 on top of city permit costs. Assembly Squad includes all permit costs in our fixed-price proposals — no surprises at permit issuance.
Chicago now enforces the 2021 International Existing Building Code (IEBC) with local Chicago amendments, replacing the previous 2012 code adoption. For kitchen and bathroom remodeling, the key impacts are: (1) updated energy code requiring modern U-factor and SHGC performance on any windows replaced during the remodel; (2) mandatory AFCI (arc fault circuit interrupter) protection on all new kitchen and bedroom circuits; (3) updated exhaust fan requirements mandating minimum CFM ratings and exterior discharge for all bathroom ventilation; (4) stricter lead-safe work practice requirements in pre-1978 homes (most of Chicago's housing stock). Assembly Squad designs and builds to the current 2026 code on every project — our permit applications reflect the correct code version so they are never rejected for outdated references.
Yes — all Chicago condominium renovations require both city building permits AND HOA alteration agreement approval before work can begin. The HOA process is separate from the city permit process and typically takes 2–6 weeks depending on building management. Most Chicago high-rise buildings require architectural drawings, proof of contractor licensing and insurance (minimum $2M general liability with the building named as additional insured), a signed alteration agreement, and sometimes board approval at a scheduled meeting. Assembly Squad manages all HOA submissions in-house with a 97% first-submission approval rate — built over 13 years of working across every major Chicago building. See our dedicated condo permit guide for the full process.
Remodeling without required permits in Chicago creates serious risks: stop-work orders halting all construction; mandatory demolition of completed work to allow inspection of concealed systems (at the homeowner's expense); city fines of $500–$10,000 per violation per day under Chicago Municipal Code Section 14A-1-105; home sale complications as Chicago requires permit disclosure at point of sale; and insurance voidance for claims related to unpermitted construction. Assembly Squad pulls permits on every project without exception — not just for code compliance, but because properly permitted work is a documented asset that increases resale value and eliminates legal exposure.
Yes — Chicago greystones and vintage buildings are common Assembly Squad projects. The permit process is identical, but vintage buildings frequently reveal infrastructure issues during demo that add to scope: galvanized plumbing ($4,500–$12,000 to replace), knob-and-tube wiring ($3,500–$8,000 to update to modern code), and non-standard room dimensions requiring fully custom cabinetry. Chicago's EPA lead-safe renovation rules require certified lead-safe work practices in all homes built before 1978 — which is most of Chicago's greystone, brownstone, and bungalow stock. Assembly Squad is EPA Lead-Safe Certified and performs pre-demo lead testing on all pre-1978 projects. See our Chicago brownstone kitchen renovation guide for more detail.
Yes — Assembly Squad handles every aspect of permit management on every project: application preparation, electronic submission, reviewer comment response, HOA alteration agreement submission, certificate of insurance generation, permit posting, rough and final inspection scheduling, and permit close. Homeowners have zero involvement in the permit process — we report permit status in every daily update. All permits are submitted on day one of the project so the 7–9 week Chicago review runs concurrent with design finalization, never adding to your construction timeline. Permit costs are included in our fixed-price proposals with no surprises at issuance.
