What requires a building permit in Indianapolis?
Most new construction, additions, and major remodels in Indianapolis require a building permit. You’ll likely need a permit if your project involves:
- New construction: Single-family, multifamily, or commercial buildings
- Additions: Expanding an existing structure or altering its footprint

- Mechanical, electrical, or plumbing work: New systems or substantial upgrades
- Accessory structures: Garages, sheds, fences over 6 feet, decks, and carports
- Demolitions: Full or partial building removals
If your project takes place within Marion County, permitting falls under the Department of Business and Neighborhood Services (DBNS).

- Painting, flooring, cabinetry, or trim work
- Replacing doors and windows (if the rough opening isn’t altered)

- Building a detached accessory structure under 120 sq. ft. and not on a permanent foundation

Indianapolis building permit application process
Here’s a step-by-step guide for navigating the city of Indianapolis building permits process:
Step 1: Determine permit requirements
Start by reviewing your scope of work to identify which permits are required. Depending on the project, you may need to apply for a:
- Improvement location permit
- Structural permit
- Electrical, mechanical, and plumbing (MEP) permits
- Right of way permit
The City of Indianapolis also enforces the Indiana Building Code, so state requirements may also apply.
Step 2: Prepare necessary documentation
Required documents vary by project, but commonly include:
- A completed plan submittal checklist
- Site plan and property survey
- Construction drawings (signed and sealed)
- Energy code compliance forms
- Structural calculations (for new construction)
- Contractor license and proof of insurance
Step 3: Submit application
Use the Indianapolis Accela Citizen Access Portal to apply online. First-time users must create an account. You’ll upload your documents and pay any applicable intake or plan review fees.
If needed, applications can also be submitted in person at the BNS office:
- Location: 1200 Madison Ave, Suite 100, Indianapolis, IN 46225
- Hours: Monday–Friday, 8:00 a.m. to 5:00 p.m.
Step 4: Plan review and approval
Applications go through a multi-department plan review.
Depending on the scope, this may include:
- Building and zoning review
- Health or fire department review
- State building review (for large commercial projects)
Step 5: Permit issuance and inspections
Once your plans are approved and fees are paid, your permit is issued. You must post the permit on site and schedule inspections as the work progresses.
You’ll need to schedule Inspections the Permit Portal at key stages. You can also view inspection results and status updates in the portal.
