Chicago Building Department 2026: Permits, Inspections & Services

Chicago, Illinois · 2026 permit and inspection guide

Chicago Building Permits, Inspections and Department of Buildings Services

If you need a building permit in Chicago, the agency you are looking for is officially the City of Chicago Department of Buildings (DOB). It handles building permits, construction inspections, code enforcement, trade licensing and many building-safety services within Chicago city limits.

Chicago Department of Buildings Contact Information

The Department of Buildings serves properties inside the City of Chicago. Do not assume a Chicago mailing address means DOB has jurisdiction; suburban Cook County municipalities issue their own permits.

If you visit City Hall about an application, bring your permit application number, property address and applicant information. Having the application number is especially useful because Chicago’s online status system provides more detail when you search by application number rather than only by street address.

Do You Need a Building Permit in Chicago?

Chicago states that a permit is required before most construction, demolition and repair work begins. The exact route depends on the work. A kitchen remodel involving plumbing, electrical work or wall changes is very different from replacing flooring or painting a room.

Which Chicago Permit Process Should You Use?

Chicago does not route every project through one identical permit process. This is where many homeowners and first-time applicants become confused.

1. Express Permit Program

The Express Permit Program (EPP) is a web-based system for many repairs, replacements, smaller improvement projects and certain administrative changes. The City says customers can apply, check status, pay applicable fees and view inspection information online.

Examples listed in Chicago’s current Express Permit instructions include:

• electrical work;
• exterior window or door replacement;
• fences or trash enclosures;
• fire alarm systems;
• nonstructural interior alterations;
• masonry work;
• mechanical/HVAC work;
• plumbing work;
• porch, deck, balcony or fire-escape repair;
• reroofing;
• detached frame garages;
• small-scale solar PV systems;
• scaffolding and certain temporary structures.

That does not mean every project with one of those labels automatically qualifies. Scope, property type, zoning, landmark status and structural complexity can change the required review.

Open the City’s permit instructions and match the actual work to the available application category.

2. Standard Plan Review

Standard Plan Review (SPR) is the main path for projects requiring architectural plans when another specialized review program is not appropriate. This may include new construction, substantial rehabilitation and other plan-based work.

3. Self-Certification

Chicago’s Self-Certification program allows eligible projects to use a qualified design professional who accepts responsibility for code compliance under the program. It is not simply a faster application button available to every homeowner.

4. Developer Services

Developer Services is intended for qualifying moderate-to-complex projects. The City’s Assisted Developer Services process can assign a DOB project administrator and may use third-party plan review. Those review charges can be separate from the normal building permit fee.

5. Specialty Permits

Separate procedures exist for work such as demolition, elevators and conveyances, signs, sewer connections, water-service work and temporary structures. Sprinkler and standpipe permitting may involve the Chicago Fire Department rather than being handled entirely as an ordinary DOB building permit.

How to Apply for a Chicago Building Permit

1. Write down the exact scope of work.
   Be specific. “Remodel kitchen” is less useful than identifying wall removal, plumbing fixture relocation, electrical circuits, ventilation work, windows and structural changes.
2. Check the property’s zoning before spending heavily on design.
   Zoning and building-code approval are different. A project can be technically buildable yet still conflict with use, setbacks, density, parking or other zoning rules.
3. Identify the correct permit route.
   Open the official Building Permit Application Instructions. Review Express Permit, plan-based and specialty permit categories.
4. Determine whether professional plans are required.
   New construction and significant alteration work commonly require documents prepared by licensed design professionals. Do not upload incomplete drawings simply to “get in line.”
5. Verify contractors before connecting them to the permit.
   Use the City’s active contractor lookup. An inactive or expired City license or missing insurance information can interfere with permit issuance.
6. Start the application using the correct City system.
   Follow the instructions for your permit type. Chicago notes that its plan-based online workflow still contains some older terminology, so use the City’s current instructions rather than guessing from the portal labels.
7. Upload the required plans and supporting documents.
   Make sure addresses, scope, contractor information and drawing details are consistent across documents. Conflicting information creates avoidable corrections.
8. Watch for reviews, holds and corrections.
   Use the official Building Permit Application Status system. An unresolved correction or hold can prevent issuance.
9. Pay assessed fees and confirm the permit is actually issued.
   An application under review is not permission to start work.
10. Complete required inspections before covering work.
    Keep the permit number accessible and coordinate inspection stages with the contractor and inspector.

How to Check a Chicago Building Permit Application

The City maintains a separate online system for applications currently moving through review.

1. Go to the Building Permit Application Status website.
2. Accept the City’s terms if prompted.
3. Search with the building permit application number whenever possible.
4. Review the application status, review activities, holds and available corrections.
5. If plans were submitted through the applicable plan-review system, authorized project participants may have access to additional ProjectDox information.

The City says its status site primarily provides information for applications started during the preceding 36 months. Searching only by street address can return less information than searching with the application number.

If a review shows an unresolved hold, blank/incomplete activity or open correction, the application may not be ready for issuance. For zoning review, the City’s status guidance specifically distinguishes zoning approval requirements from other review statuses.

How to Search Issued Permits, Inspections and Building Records

If you are researching an existing building rather than tracking your own pending application, use the City’s public Building Permit and Inspection Records system.

This can be useful when buying a property, planning renovation work or trying to understand previous permit and inspection activity.

Remember that an old permit record does not prove the work was actually completed correctly. The City itself warns that permit and inspection records are informational and may not represent the current physical condition of a property.

How to Request a Chicago Building Inspection

For supported permit inspections, Chicago provides an online DOB inspection request form.

1. Open the official Inspection Request form.
2. Enter the permit number and property address.
3. Select the inspection option and inspection type.
4. Provide the name, telephone number and email for the person who will be available at the property.
5. Enter a requested inspection date when applicable.
6. Submit once. The City specifically asks users not to create duplicate inspection requests.

DOB states that requests are handled on a first-come, first-served basis unless a particular appointment date is selected. The online form also says requests to reschedule or cancel a scheduled inspection should be submitted at least 24 hours before the appointment.

Elevator inspections and restaurant start-up inspections have separate request paths. For service requests not supported by that form, the City directs users to 311.

What to Have Ready for an Inspection

• permit number and approved permit information;
• safe access to the area being inspected;
• approved drawings where applicable;
• the responsible contractor or knowledgeable site contact;
• work exposed and accessible for the inspection stage;
• previous correction information if this is a reinspection.

Do not schedule a final inspection simply because the contractor says the project is “basically finished.” Confirm that the work relevant to the inspection is actually complete and accessible.

Chicago Building Permit Fees

There is no reliable single flat price for a Chicago building permit. Cost can depend on project scope, occupancy, construction type, size and other code-based factors. Additional reviews, specialty permits or professional services may also add costs.

The City provides an official building permit fee calculator. Treat the calculator as an estimate until your actual application has been reviewed and assessed.

For budgeting, separate these possible costs:

• building permit fee;
• zoning-related charges where applicable;
• trade or specialty permit fees;
• architect or engineer fees;
• third-party review costs for applicable programs;
• reinspection or other project-specific charges;
• contractor licensing/registration costs borne by the contractor.

Verify a Contractor Before the Permit Is Issued

Chicago provides a public database of active trade contractors. The lookup shows information such as license type, license number, business name, expiration date and available insurance or bond expiration information.

1. Open the Active Trade Contractors page.
2. Search for the contractor or browse the appropriate trade category.
3. Confirm that the business name matches the company you hired.
4. Check that the listed license is active.
5. Confirm that the contractor attached to your permit is the contractor actually performing the regulated work.

Chicago’s permit-status guidance notes that an inactive or expired City contractor license, or missing current insurance information where required, can prevent permit issuance.

Building Codes Used in Chicago in 2026

Chicago uses its own Chicago Construction Codes, not simply an unmodified statewide or generic International Building Code. The code family covers building construction, rehabilitation of existing buildings, electrical work, energy requirements, accessibility, fire prevention and other regulated work.

The City’s current code resource identifies the 2019 Chicago Building Code in Title 14B for most new-construction permit applications started on or after August 1, 2020, along with the Chicago Building Rehabilitation Code for applicable work in existing buildings.

However, Chicago is continuing a multi-year code-modernization process. The City posted an October 6, 2026 alert concerning implementation of Phase 3 Construction Codes Modernization. Because effective dates can differ by code area and application date, anyone designing a 2026 project should verify the controlling provisions immediately before submitting plans.

Check the current Chicago Construction Codes.

Check Zoning Before Signing a Lease or Starting Design

Chicago’s Department of Planning and Development administers zoning and reviews permit applications for zoning compliance. For a business, addition, new dwelling unit or change of use, zoning can affect whether the planned project is allowed at the property.

The City specifically recommends checking zoning and current code requirements before a business owner takes on major financial commitments such as signing a lease.

Start with the Chicago Department of Planning and Development and its official zoning resources.

Work That May Not Require a Chicago Building Permit

Chicago publishes a list of limited repair and alteration work that may be permit-exempt. Examples identified by the City’s CHI311 guidance include certain:

• interior finishes such as paint, wallpaper, carpet, tile and hardwood flooring;
• cabinetry or furniture without plumbing or electrical connections;
• in-kind replacement of some non-fire-rated interior doors;
• limited residential fixture replacements;
• small sheds or gazebos meeting specified conditions;
• limited drywall work where regulated underlying systems are not altered;
• certain low-voltage wiring work;
• limited fences and other minor work meeting specified conditions.

There are important exceptions involving building size, dwelling-unit count, fire ratings, landmark status, dimensions, location and scope. Permit exemption also does not mean zoning and other code requirements disappear.

Before relying on an exemption, review the City’s When Is a Building Permit Not Required? guidance and confirm that your exact project fits the current rule.

Certificate of Occupancy

Some buildings and projects require a Certificate of Occupancy before the applicable space can lawfully be occupied. Chicago provides an online Certificate of Occupancy application that requests building, owner, permit and inspection information.

The City’s form warns that a Certificate of Occupancy cannot be issued if installation is incomplete or deficiencies are found, and additional inspections can lead to additional charges.

Open the official Certificate of Occupancy application.

Building Violations and Complaints

DOB also performs code-enforcement and complaint-related inspections. Chicago identifies four broad inspection situations: permit inspections, recurring annual or quarterly inspections, business-license inspections and inspections prompted by complaints.

If you need to report a building condition rather than schedule an inspection connected to your active permit, use Chicago 311. Keep the correct property address and a clear description of the condition ready.

If you are researching an existing property’s history, use the building-record search, but do not assume that the absence of a currently displayed violation proves the building is fully code compliant. The City’s records system expressly warns against that assumption.

Common Reasons a Chicago Permit Gets Delayed

• wrong permit or review type selected;
• scope of work is too vague or inconsistent;
• plans do not match the application description;
• zoning issues were not resolved first;
• required professional drawings are incomplete;
• open corrections were not answered;
• an application hold remains unresolved;
• contractor license or insurance information is not current;
• special approvals such as landmark, fire, water, sewer or other agency review are still pending;
• fees have not been fully resolved.

When an application is already in review, do not start a second application simply because the first one appears slow. First check its status and corrections. Duplicate or conflicting applications can create more confusion.

Chicago vs. Cook County Suburbs: Use the Correct Department

The Chicago Department of Buildings handles properties under City of Chicago jurisdiction. Nearby municipalities use their own building departments, adopted codes, fees and permit systems.

If the project is outside Chicago city limits, these nearby guides may help:

• Berwyn Building Department permit and inspection guide
• Blue Island Building Department guide
• Calumet City Building and Zoning permit guide
• Arlington Heights Building & Life Safety guide

A contractor who regularly works throughout Cook County may deal with several completely different permit authorities in the same week. Always use the municipality responsible for the project’s actual address.

Before You Start Work: Simple Checklist

• Confirm the property is actually inside Chicago jurisdiction.
• Define the complete project scope.
• Check zoning before expensive design or construction commitments.
• Identify Express Permit, plan-based or specialty permit requirements.
• Hire a licensed design professional if the project requires one.
• Verify contractors through the City’s active license database.
• Submit complete and consistent application documents.
• Resolve every correction and hold.
• Confirm the permit is issued before regulated work starts.
• Schedule each required inspection before work is concealed.
• Complete final approvals and Certificate of Occupancy requirements where applicable.

A little preparation here can save a lot of frustration later. Chicago’s permitting system has several paths, but the process becomes much easier once you know exactly what work you are doing, which review path applies and what documentation the City expects.
