How to Get Building Permits in Chicago: Contractor and Homeowner Guide
Chicago’s building permit process has a reputation for being slow, confusing, and occasionally infuriating — and that reputation is mostly earned. The Department of Buildings (DOB) oversees all construction permits in the city, and the process ranges from straightforward (an Easy Permit for a new water heater takes 15 minutes) to months-long (a standard permit for a major renovation requiring zoning review and aldermanic sign-off). Use our renovation ROI calculator for detailed numbers. Understanding which category your project falls into is the first step toward keeping your timeline on track.
This guide covers the complete permit process for homeowners and contractors in Chicago, from determining which permit type you need to scheduling inspections after the work is done.

Easy Permits — Same Day, Minimal Hassle
Easy Permits cover routine maintenance and replacement work where you’re not changing the footprint, layout, or structural elements of the building. These are available online through the Chicago DOB website and can be issued within 15–30 minutes.
What Qualifies for an Easy Permit
- Like-for-like replacements: water heaters, furnaces, AC units, windows (same openings)
- Roofing (re-roof over existing, or tear-off and replace)
- Interior non-structural demolition
- Minor plumbing (fixture replacements without moving supply/drain lines)
- Minor electrical (adding outlets, replacing panels up to 200 amps)
How to Get an Easy Permit
- Go to the Chicago DOB online permit portal (chicagodob.org)
- Log in or create an account
- Select “Easy Permit” and choose the work type
- Enter property address, scope of work, and contractor information
- Pay the fee ($60–$250 depending on work type)
- Receive your permit — typically within minutes
| Easy Permit Type | Fee | Inspection Required? |
|---|---|---|
| Water Heater | $60 | Yes |
| Furnace / Boiler | $60 | Yes |
| Roofing | $75–$150 | Yes |
| Electrical (Minor) | $75–$150 | Yes |
| Plumbing (Minor) | $75–$150 | Yes |
| Window Replacement (Same Size) | $100 | No (unless 6+ windows) |
Standard Permits — The Full Process
Standard permits are required for any work that involves structural changes, zoning review, changes to the building footprint, or major system alterations. These take significantly longer and require more documentation.
Required Documents for a Standard Permit
- Architectural drawings: Floor plans, elevations, cross-sections drawn by a licensed architect or structural engineer (required for structural work, additions, and new construction)
- Plat of survey: A current survey showing the lot dimensions, building location, and any easements
- Contractor license information: Your GC must hold a Chicago General Contractor License. Trade contractors (electrical, plumbing, HVAC) need their own Chicago licenses.
- Insurance certificates: General liability and workers’ compensation for all contractors
- Structural calculations: Required for additions, decks, porches, and any work affecting load-bearing walls
Standard Permit Timeline
| Step | Typical Duration | Notes |
|---|---|---|
| Application Submission | Day 1 | Online or in person at DOB |
| Initial Review | 1–2 weeks | DOB checks completeness of submission |
| Plan Review (Architectural) | 2–6 weeks | Longer for complex projects |
| Zoning Review | 1–4 weeks | Concurrent with plan review if no variances needed |
| Corrections (If Needed) | 1–3 weeks | Respond to DOB comments on plans |
| Permit Issuance | 1–3 days after approval | Pay fees and receive permit |
| Total | 4–12 weeks | Complex projects can take 16+ weeks |
Standard Permit Fees
| Project Type | Typical Fee Range |
|---|---|
| Kitchen/Bathroom Remodel | $250–$500 |
| Basement Finishing | $300–$600 |
| Deck / Porch | $250–$500 |
| Room Addition | $500–$1,500 |
| New Construction (House) | $2,000–$5,000+ |
| Two-Flat / Multi-Unit | $1,000–$3,000 |
Zoning and Aldermanic Review
If your project doesn’t conform to Chicago’s zoning code — for example, you’re adding a garage that exceeds lot coverage limits, or building an addition that doesn’t meet setback requirements — you’ll need a zoning variation. This introduces another layer of review:
- Zoning Pre-Screen: Before filing for a permit, get a zoning pre-screen from DOB to identify potential conflicts.
- Aldermanic Sign-Off: Many zoning variations in Chicago require the local alderman’s support. This is an informal but important step — aldermen have significant influence over zoning decisions in their wards.
- Zoning Board of Appeals: If a formal variation is required, you’ll present your case to the Zoning Board of Appeals. Hearing dates are scheduled monthly, and the process typically adds 2–4 months to your timeline.
For most residential renovation projects that stay within the existing building footprint, zoning isn’t an issue. It becomes a factor with additions, new garages, coach houses, and changes to non-conforming structures.
Inspections
After receiving your permit, inspections are required at various stages of construction. Common inspection points include:
- Foundation / Footing: Before pouring concrete for foundations
- Rough Framing: After framing but before drywall
- Rough Plumbing: After plumbing is installed but before walls are closed
- Rough Electrical: After wiring but before walls are closed
- Final Inspection: After all work is complete
Schedule inspections through the DOB portal or by calling 311. Inspectors typically arrive within a 4-hour window. Failed inspections require corrections and re-inspection, adding time and potentially additional fees. Having your contractor present during inspections is strongly recommended.
Common Project-Specific Permit Scenarios
Kitchen Remodel
If you’re keeping the same layout (no wall changes, no plumbing moves), you may only need Easy Permits for individual trades — electrical for new outlets, plumbing for a new dishwasher connection. If you’re moving the sink, adding gas lines, or removing walls, you need a Standard Permit with architectural drawings. Budget $250–$500 in permit fees and 2–6 weeks for approval on a layout-changing kitchen remodel.
Basement Finishing
Finishing a basement in Chicago requires a Standard Permit. The DOB requires egress windows (minimum 5.7 sq ft of openable area) in any basement bedroom, proper ceiling height (minimum 6’8″ in habitable areas), waterproofing measures, and fire-rated enclosure for mechanicals. Expect $300–$600 in permit fees and 4–8 weeks for review. Many Chicago basements have structural columns, low ceilings, and HVAC ductwork that limit usable ceiling height — verify before designing.
Deck Construction
All new decks require a Standard Permit in Chicago. You’ll need a site plan showing the deck location relative to property lines (must meet setback requirements), structural drawings with post spacing and joist sizing, and a plat of survey. The DOB is particularly strict about ledger board connections (how the deck attaches to the house) and guardrail height (42″ minimum in Chicago, versus 36″ in most suburbs). Permit fees run $250–$500.
Coach House / ADU
Chicago legalized coach houses (accessory dwelling units) in 2020, allowing homeowners to build a secondary residential unit on their lot. However, the requirements are significant: the lot must be at least 3,125 sq ft, the coach house is limited to 2 stories, and it must meet all building code requirements for a new residential structure. Permits for coach houses go through the full Standard Permit process with zoning review and can take 3–6 months. Construction costs typically run $200,000–$400,000.
Tips for a Smoother Permit Process
- Hire an architect for anything beyond basic remodeling. DOB plan reviewers reject incomplete or unprofessional drawings. A licensed architect’s stamp reduces rejection risk and speeds review.
- Use a licensed Chicago contractor. Contractors without a Chicago GC License cannot pull permits. Verify your contractor’s license through the DOB online lookup before signing a contract.
- Check your lot’s zoning before planning. Use the Chicago Zoning Map (available online) to verify your property’s zoning classification and understand what’s allowed without a variance.
- Be proactive with your alderman. For any project that might need zoning review, introducing yourself and your project to the local alderman’s office early can smooth the process significantly.
- Keep permits posted during construction. Chicago requires permits to be posted visibly at the work site. Failure to post can result in fines and stop-work orders.

Permit Cost Summary by Project Type
Here’s a full breakdown of what you’ll pay in permit fees, plan review, and associated costs for the most common residential projects in Chicago:
| Project | Permit Fee | Plan Review | Architect Needed? | Total Permit-Related Costs |
|---|---|---|---|---|
| Water Heater Replacement | $60 | None | No | $60 |
| Furnace Replacement | $60 | None | No | $60 |
| 10-Window Replacement (Same Size) | $100 | None | No | $100 |
| Roof Replacement | $75–$150 | None | No | $75–$150 |
| Kitchen Remodel (Layout Change) | $250–$500 | Included | Recommended | $2,000–$5,000 (with architect) |
| Basement Finishing | $300–$600 | Included | Yes | $2,500–$6,000 (with architect + egress) |
| Deck Construction | $250–$500 | Included | Yes (structural calcs) | $1,500–$4,000 |
| Room Addition (500 sq ft) | $500–$1,500 | Included | Yes | $4,000–$10,000 |
| Coach House / ADU | $1,000–$3,000 | Included | Yes | $8,000–$15,000 |
The architect cost is often the biggest surprise for homeowners. The permit fee itself is modest — it’s the architectural drawings, structural calculations, and plan review preparation that drive total permit-related costs into the thousands. For major projects, architect fees typically run 8–15% of total construction cost or a flat fee of $2,000–$10,000. This is money well spent — professional drawings reduce rejection risk, speed plan review, and produce a better end result. Some contractors include architectural services in their scope, which simplifies the process but may limit your design options.

Frequently Asked Questions
How long does it take to get a building permit in Chicago?
Easy Permits are issued same-day (often within minutes). Standard Permits take 4–12 weeks for typical residential projects, and 12–16+ weeks for complex projects requiring zoning review. The biggest delays come from incomplete plan submissions that require corrections and resubmission.
How much does a Chicago building permit cost?
Easy Permits range from $60 to $250. Standard Permits range from $250 to $5,000+ depending on project scope. Additional fees may apply for zoning review, plan review, and inspections. Budget $250–$600 for a typical kitchen or bathroom remodel permit.
Can I do my own work without a permit in Chicago?
Only cosmetic work (painting, flooring, cabinet replacement) is exempt from permits. Any work involving electrical, plumbing, structural changes, or mechanical systems requires a permit. Working without permits risks fines ($500–$1,000 per violation per day), stop-work orders, and liability if something goes wrong. Unpermitted work can also create problems when selling. Use our closing cost calculator to budget for permit fees alongside other closing expenses.
Do I need a licensed contractor for permit work in Chicago?
Yes. To pull a Standard Permit, the work must be performed by a contractor holding a valid Chicago General Contractor License. Trade work (electrical, plumbing) must be performed by appropriately licensed tradespeople. Homeowners can perform some work on their own property, but the permit still requires a licensed contractor on record for most project types.
What happens if I get caught without a permit?
The DOB can issue fines of $500–$1,000 per violation per day, issue a stop-work order until permits are obtained, and require you to open finished walls for inspection. When selling the property, unpermitted work can surface during the title search or buyer’s inspection, requiring costly remediation. Use our home selling guide for detailed numbers. It’s almost always cheaper and less stressful to get the permit upfront.
How do Chicago permits compare to suburban permits?
Suburban permits are generally faster, cheaper, and less complex. Most DuPage, Lake, and Will County municipalities process standard residential permits in 1–3 weeks versus Chicago’s 4–12 weeks. Permit fees are lower in the suburbs ($100–$300 for typical projects vs. $250–$500+ in Chicago). The biggest difference is the level of plan review required — Chicago’s DOB scrutinizes drawings more thoroughly, which means architectural plans need to be more detailed and professionally prepared. Suburban municipalities often accept simpler drawings for routine projects like decks, bathrooms, and kitchen remodels. If you’re renovating in an unincorporated area of a collar county, permit requirements may be minimal — check with the county building department.
Can I pull my own permits in Chicago as a homeowner?
For Easy Permits (water heaters, furnaces, roofing), yes — homeowners can pull permits for work on their own property. For Standard Permits involving structural, electrical, or plumbing work, the permits must be associated with a licensed contractor. Even if you’re doing the work yourself (which is allowed in limited circumstances for owner-occupied properties), the electrical and plumbing portions require licensed tradespeople. Never try to skip the contractor requirement — the DOB cross-references contractor licenses during plan review, and unpermitted trade work is a code violation.
