Indianapolis, Indiana Building Permit Guide

The Department of Business and Neighborhood Services (BNS) handles licensing, permitting and inspections for the City of Indianapolis, whose balance had 901116 residents by the Census Bureau’s 2025 estimates. The City’s Building Standards and Procedures (Chapter 536) apply throughout the territorial limits of the consolidated city.

This guide covers BNS permits in Indianapolis. The BNS fee schedule is a spreadsheet, so per-permit fees are not listed here; ask BNS for the schedule in force.

What requires a building permit in Indianapolis?

For Class 2 homes, replacing windows and doors, roofing and exterior siding stays exempt from a building permit if done by a licensed or listed contractor or an owner-occupant; since 2026 the notification forms under former Sec. 536-216 are no longer required.

After the 2025 state law HEA 1037, a local drainage permit is needed only when the project needs Construction Stormwater General Permit coverage, generally one or more acres disturbed. Floodplain development permits (flood@indy.gov) and Citizens Energy Group approval for water and sewer connections still apply to all projects. Driveways connecting to City streets need a Driveway Access Street Construction Permit, and a temporary construction access permit is valid for six months.

Before construction starts on a Class 1 structure — one used by the public, by three or more tenants, or by anyone working as another’s employee — Indiana requires a state Construction Design Release, unless the work is exempt under 675 IAC 12-6-4. One- and two-family dwellings and qualifying townhouses are Class 2 and are permitted locally where an ordinance requires it. Indiana enforces the 2014 Indiana Building Code and the 2020 Indiana Residential Code. Class 1 and Class 2 in Indiana

Who handles permitting in Indianapolis?

BNS takes applications, payments and plans through the Citizens Access Portal, or by mail to 200 E. Washington St., Suite 107; phone 317.327.8700. In the Accela Citizens Access (ACA) portal an account is required to apply, plans are uploaded as PDFs no larger than 150 MB, and a 180-day permit extension can be requested.

The local building department issues the building permit and inspects the work. On a Class 1 structure the state design release, issued by IDHS or a certified local unit, must come before construction starts; IDHS has 10 business days to respond to a complete application and 20 for a plan review. Plans for Class 1 work over 30,000 cubic feet must be prepared by a registered architect or engineer. The Construction Design Release

Class 2 and Class 1 permits in Indianapolis

Class 2 (residential)

Permits follow a set order: infrastructure review and drainage permit (317.327.8583), then the improvement location permit, then the structural permit. A drainage inspection is needed before the improvement location permit if the subdivision was not pre-approved for drainage or the addition is over 400 square feet.

Class 1 (commercial)

A structural permit application needs a pre-permit plan review, payment of the initial fees ($478.00) and three sets of construction plans. Commercial projects may also need a construction design release from the Indiana Department of Homeland Security.

Since 1 January 2026, a unit that requires permits for one- and two-family work must review plans within 7 business days and offer inspections within 3, and the applicant may use a private reviewer or inspector instead (IC 36-7-2.5). Local permits and the 2026 deadlines

Indianapolis permit costs and fees

BNS fees changed on January 5, 2026; craft permits for electrical, HVAC and plumbing did not change. A failed building inspection now triggers an automatic $175 reinspection fee, and working over a stop work order costs $750 (Class 1) or $250 (Class 2).

Since February 1, 2026, owners of non-residential, Class 1 multifamily and commercial drainage projects can buy accelerated plan review for a flat $2,500 per review type; every review round is then completed in no more than five business days.

Fee schedules are revised on each jurisdiction’s own cycle, so ask the issuing department for the schedule in force on your filing date. On Class 1 work the state design release adds a $75 filing fee plus a processing fee, generally $0.050 per gross square foot. State design release fees
