Indianapolis Site Plan Requirements: Complete Guide for Building Permits

Creating a site plan for a building permit in Indianapolis, Indiana requires meeting specific requirements set by the Department of Business and Neighborhood Services (BNS). Indianapolis operates under a consolidated city-county government (Unigov) with Marion County, meaning BNS handles permitting for the entire county. The Consolidated Zoning and Subdivision Ordinance (Chapter 744) governs all development.

What Is a Site Plan and Why Does Indianapolis Require One?

A site plan is a scaled drawing showing your property boundaries, existing structures, proposed construction, setbacks, and site features. BNS requires a site plan for all building permit applications to verify compliance with the Consolidated Zoning Ordinance and the Indiana Building Code. Look up your property's zoning through the Indy GIS portal at maps.indy.gov.

Required Site Plan Elements for BNS

  • Property boundaries with accurate dimensions and total lot area
  • Setbacks from all property lines per Chapter 744
  • Existing structures with square footage, height, and use
  • Proposed construction clearly distinguished from existing
  • Lot coverage calculation
  • Parking spaces per Chapter 744 parking regulations
  • Driveways and access with dimensions
  • Landscaping and buffering per the ordinance
  • Drainage and stormwater features
  • North arrow and scale
  • Marion County parcel number

Regional Center and Transit-Oriented Development

Indianapolis has adopted progressive development standards for downtown and transit corridors:

  • IndyGo BRT corridors: Transit-oriented development standards along the Red Line and future BRT routes with reduced parking and increased density
  • Form-based zones: Select areas use form-based code with build-to lines and frontage requirements instead of traditional setbacks

Stormwater Management Requirements

Indianapolis stormwater is managed by the Department of Public Works (DPW) and Citizens Energy Group:

  • Stormwater management plan: Required for projects disturbing 1 acre or more
  • Post-construction BMPs: Required for regulated projects to manage water quality and quantity
  • Green infrastructure: Indianapolis encourages bioretention, rain gardens, pervious pavement, and other LID measures
  • Stormwater utility fee: Monthly fee from Citizens Energy Group based on impervious surface
  • Combined sewer overflow (CSO): The DigIndy tunnel project addresses CSO; green infrastructure helps reduce inflow

Historic Preservation Requirements

  • Indianapolis Historic Preservation Commission (IHPC) reviews projects in designated historic districts and for individual landmarks
  • Certificate of Appropriateness required for exterior work in historic districts
