DeKalb Building Department Contact Information

When calling, have the project address, type of work and a short description of the project ready. This makes it much easier for staff to tell you which application, plans and inspections apply.

Do You Need a Building Permit in DeKalb?

The City says building permits are required for virtually all construction, alteration, repair, demolition and movement of buildings or structures within the City of DeKalb.

That includes many projects homeowners may think of as routine. The exact application depends on the work.

Projects the City specifically says do not require a permit

The City’s published Building & Code FAQ identifies three common exceptions:

• Replacement windows and doors when the size of the existing opening does not change.
• Re-roofing when roof sheeting is not removed.
• Exterior siding.

How to Apply for a DeKalb Building Permit in 2026

DeKalb supports online building-permit applications through BS&A. The City also publishes project-specific applications that must be completed and uploaded with an online submission.

1. Confirm the property and proposed work.
   Make sure the parcel is inside the City of DeKalb and write down exactly what will be built, removed, replaced or altered. For exterior work, also think about setbacks, lot lines, easements and drainage.
2. Check zoning before spending money on plans or materials.
   Additions, accessory structures, signs, commercial uses and many site improvements can have zoning requirements separate from the building code. Use the City’s official zoning resources and maps ↗. For project-specific zoning questions, Community Development lists 815-748-2361.
3. Download the correct City permit form.
   Open the Building Permits & Fees page ↗. The City currently provides applications for new construction/alterations, decks, garages and sheds, fences, electrical, HVAC, plumbing, roofing, solar, pools, demolition, signs, driveways/sidewalks/patios, temporary structures and other work.
4. Prepare the supporting documents.
   Depending on the project, this can include a site plan, construction drawings, work valuation, square footage, property-owner information, contractor information, trade details and outside-agency approvals. Major construction normally needs more documentation than a simple trade permit.
5. Create or sign in to your BS&A account.
   Go to the City of DeKalb BS&A portal ↗. Homeowners and contractors applying online must have an account. The City also instructs users to link the account to the appropriate contractor or homeowner record through BS&A.
6. Upload the completed application and plans.
   Enter the project information requested by the portal and upload the completed City application plus the supporting files for the project. Pay any plan-review amount required at submission.
7. Respond to plan-review comments.
   New construction, additions, major alterations and work affecting egress, structure or major building systems generally require plan review. The City’s stated goal is to issue initial review comments within about two weeks, although actual timing depends on project size and workload.
8. Pay the calculated permit fee and wait for issuance.
   After required corrections are resolved and plans are approved, the City calculates the permit fee and notifies the applicant. Pay the required amount and make sure the permit has actually been issued before starting regulated construction.

Documents and Sign-Offs That Can Delay a Permit

A permit can be technically complete but still stall because a required outside approval or separate City review is missing. This matters especially for new construction and commercial projects.

DeKalb Building Permit Fees

There is no single flat price for every DeKalb building permit. The City separates its published building fees into schedules for residential and commercial work, and the official permit page clearly labels the schedules “subject to change.”

Common residential fee examples from Schedule B

For new multifamily, commercial, industrial and institutional projects, the City’s Schedule C publishes a $1,000 building plan-review fee at application submittal and a separate square-footage-based building fee. An Engineering Site Improvement plan review can also carry a separate $1,000 fee under that schedule.

How to Schedule a DeKalb Building Inspection

For new residential construction, the City’s inspection packet instructs applicants to call 815-748-2070 or 815-748-2073 to schedule inspections.

• Allow a minimum of 24 hours’ notice for regular inspections.
• Allow 72 hours for final inspections.
• Published inspection hours are Monday-Friday, 8:00 a.m.-3:30 p.m.
• City-approved, stamped/signed plans must be available on site for applicable inspections.
• Do not cover regulated work before the required inspection.

BS&A also provides a Schedule an Inspection service for City of DeKalb building records. If the online option for your permit is available, sign in to the same City portal used for permit records and fees.

Typical new-home inspection sequence

The exact sequence depends on the project, but the City’s residential packet identifies inspections such as:

1. Footings — before concrete is poured.
2. Foundation wall — before foundation-wall concrete is poured.
3. Backfill — before the foundation is backfilled.
4. Underground work — plumbing, electrical and underground ducts before they are covered.
5. Garage/basement slab stages where applicable.
6. Electrical service and utility-related work.
7. Rough electrical, plumbing and HVAC.
8. Framing.
9. Insulation before drywall conceals the work.
10. Final building and applicable trade inspections.

Final Inspection and Occupancy

New residential construction has stricter closeout requirements than a simple repair permit. The City’s residential inspection instructions state that final inspections are not to be performed when furniture or personal belongings are already on the premises, and occupancy before approval can lead to enforcement action.

For applicable new residential projects, the inspection packet also requires the final grading survey to be submitted before the final occupancy inspection. Follow the project-specific closeout instructions issued with your approved permit rather than assuming the last trade inspection automatically authorizes occupancy.

Check a Permit, Pay a Fee or Find Building Records

The City of DeKalb’s BS&A service is useful even after the application is submitted. Its Building Department services include:

• Apply for a permit.
• Search Building Department records.
• Pay a Building Department fee.
• Schedule an inspection.
• Use detailed record search functions.

Micro-step: Open BS&A → confirm City of DeKalb is selected → sign in → choose the Building Department service you need → search by the available permit/property information.

The City’s online-payment page also accepts building-permit payments. It currently states a convenience fee for online card or bank-account payments, so review the amount displayed before completing the transaction.

Contractor Registration in DeKalb

If you are hiring someone to perform permitted work, contractor status is worth checking before the permit application gets too far. DeKalb requires annual registration for several contractor categories.

The City’s current 2026 general contractor registration form shows a $50 annual fee for applicable general/HVAC/electrical registration categories and states that required insurance must be on file before registration is effective and work is permitted.

Building Codes Used in DeKalb in 2026

DeKalb updated its construction-code framework in connection with Illinois requirements. The City’s current Building Codes page lists these principal editions:

The City’s code page also references applicable ADA, radon, elevator, smoke-detector and carbon-monoxide requirements. Local amendments and project-specific rules matter, so designers and contractors should verify the controlling provisions before finalizing plans.

Review DeKalb’s Current Building Codes ↗

Zoning, Setbacks and Site Approval

A building permit answers construction-code questions; it does not automatically mean the proposed location or land use complies with zoning.

DeKalb’s Unified Development Ordinance covers matters such as zoning districts, permitted uses, development standards, parking, signs, subdivision rules, drainage, site-plan review, appeals and variances. The City provides an official zoning map and an interactive map.

This is especially important before building a garage, shed, addition, fence, commercial improvement, sign or other exterior project. Checking zoning first can save the frustration of preparing a construction plan that cannot be approved at the proposed location.

Code Compliance and Property Complaints

The Building & Code Compliance Division also handles property-maintenance matters. This is separate from applying for a construction permit.

Typical issues can include tall grass and weeds, trash, snow or ice issues, inoperable or unlicensed vehicles and other property-maintenance concerns.

• Business-hours building/code number: 815-748-2070
• After-hours non-emergency number: 815-748-8400
• Emergency: 911

Which DeKalb Service Do You Need?

Avoid These Common Permit Problems

• Starting before issuance: submitting an application is not the same as receiving an approved permit.
• Using the wrong jurisdiction: confirm the property is actually inside City of DeKalb limits.
• Skipping zoning: a structurally sound project can still fail zoning or site requirements.
• Uploading only the online form: the City requires the appropriate completed permit application and supporting documents.
• Missing outside sign-offs: KWRD, School District, Health Department or Engineering review may apply to certain projects.
• Using an unregistered contractor: contractor registration issues can delay permit approval.
• Covering work early: underground, rough and concealed work may need inspection before it disappears behind concrete, soil, insulation or drywall.
• Scheduling the final too late: new residential final inspections require more advance notice than ordinary inspections.

Frequently Asked Questions

Before You Submit

For most DeKalb projects, the smoothest path is simple: confirm jurisdiction → check zoning → choose the correct application → collect the plans and required sign-offs → submit through BS&A → respond to review comments → pay the permit fee → obtain the issued permit → schedule inspections before work is covered.

If your project is unusual, call the Building & Code Compliance Division before paying for drawings or beginning construction. A short conversation early can prevent a much more expensive correction later.
