Find your zoning code

Look up your Indianapolis zoning district

Before design begins, confirm the district your lot sits in. The Indianapolis zoning map lets you search by street address or parcel number and shows the base district plus any overlays that affect what you can build.

  1. 1Open the Indianapolis zoning map and accept the parcel viewer disclaimer.
  2. 2Search by street address or parcel (tax) number to find your property.
  3. 3Note your base district and any overlays, then match them to the standards below.

Zoning maps are for general research only. Verify districts, overlays, and permitted uses with the Indianapolis planning department before making decisions — or send us your address and we'll confirm it for you.

Overlay districts to watch for

IHPCHistoric Preservation Overlay Districts

Locally designated historic areas (e.g., Lockerbie Square, Herron-Morton Place, Old Northside, Woodruff Place, Chatham Arch) regulated by the Indianapolis Historic Preservation Commission.

  • Certificate of Appropriateness (COA) required before exterior alterations, additions, or new construction
  • Design review against district-specific preservation plan guidelines
  • Staff-level administrative approval available for minor work; full Commission hearing for major changes
RCRegional Center Overlay

Overlay covering downtown Indianapolis and adjacent near-downtown neighborhoods with urban design and streetscape standards.

  • Enhanced streetscape and pedestrian-oriented building placement standards
  • Modified parking and setback requirements compared to base district
  • Design review coordination with the Regional Center Overlay design guidelines
FFFlood Control (Floodway/Floodplain) Overlay

Applies to properties within FEMA-mapped floodway and floodplain areas along Indianapolis waterways such as the White River and Fall Creek.

  • Floodplain development permit required from the Indianapolis Department of Metropolitan Development
  • Lowest floor elevation must meet or exceed base flood elevation
  • No net loss of floodway conveyance for additions or fill
THThoroughfare Plan Setback Overlay

Establishes additional building setback lines along designated arterial and collector streets identified in the Marion County Thoroughfare Plan.

  • Structures must be set back from the future right-of-way line shown on the Thoroughfare Plan
  • Applies in addition to, not instead of, the base district setback

These figures are general guidance for early planning — final requirements depend on your parcel, overlays, and any prior variances. Verify with the Indianapolis codes department or the official zoning ordinance. We confirm them for your address before design begins.

Recent work

A few Indianapolis projects

Two-Story Addition & Front Porch, Pebble Point Estates, TN

Two-Story Addition & Front Porch, Pebble Point Estates, TN

This project expands an existing home with a new two-story addition, larger L-shaped front porch, and new side entry. The addition includes a garage on the lower level and a 340 SF office on the second floor, accessed directly from the existing home's upper level. Matching shed dormers and aligned roof forms bring more natural light, increase usable space, and create a stronger connection between the existing house and the addition. The result is a larger and more functional home that maintains the character of the existing residence.

Whole-Home Remodel & Additions in Franklin, TN

Whole-Home Remodel & Additions in Franklin, TN

This project completely remodels and expands an existing home with a new sunroom, enlarged primary suite, large side addition, and expanded front porch. The design opens up the previously divided interior, creating stronger connections between the kitchen, living, dining, front porch, and backyard. A new garage and workshop take advantage of the site's changing grade, while the additions are carefully integrated with the existing home's scale, materials, and roof forms. The result is a more spacious, connected, and functional home designed to support both the homeowners' current and future needs.

Multi-Level Garage Addition with Connector, El Rancho Estates, TN

Multi-Level Garage Addition with Connector, El Rancho Estates, TN

This project adds a multi-level garage addition to an existing single-family home, connected through a two-story connector that improves circulation between the house, the garage, and the backyard. Responding to the site's changing grade, the design integrates multiple garage levels while introducing a new deck, contemporary material palette, and generous glazing. The result is a functional addition that complements the scale and architectural character of the existing home.

Local process

Permitting & review in Indianapolis

Residential additions and remodels in Indianapolis are reviewed by the Department of Business and Neighborhood Services (BNS), which handles building permits, zoning compliance review, and inspections. Most single-family remodel and addition permits are processed through the online IndyPermit portal, and projects that meet dimensional standards of the underlying D-district typically qualify for administrative (non-hearing) review. Projects located in a historic district additionally require a Certificate of Appropriateness from the Indianapolis Historic Preservation Commission (IHPC) before BNS will issue a permit.
