Land Use and Zoning Indiana 3 Minutes Read ยท published February 06, 2026 Flag of Indiana

Indianapolis, Indiana developers and property owners must follow local subdivision lot-size rules and street design standards before recording plats or opening new streets to public use. Start with the City of Indianapolis Department of Metropolitan Development for subdivision and platting procedures and application guidance Department of Metropolitan Development - Subdivision & Platting[1].

Subdivision & Street Standards - Overview

Standards govern minimum lot dimensions, frontage, lot area, lot coverage, street cross-section, pavement, curb and gutter, sidewalks, drainage, and right-of-way widths. Many technical street design and pavement, grading, and stormwater details are managed by the Department of Public Works and its engineering standards Public Works - Engineering & Street Standards[2]. When a proposed subdivision impacts utilities or existing transportation corridors, coordinate with both Planning and Public Works early.

Consult Public Works for street cross-sections early in design.

Key Checklist Items

  • Pre-application meeting with DMD/Planning to confirm zoning and subdivision type.
  • Minimum lot size and frontage per zoning district; verify exceptions or lot splits.
  • Street design: pavement width, curb, gutter, sidewalk, drainage and right-of-way dedication per DPW standards.
  • Stormwater control and detention design meeting local drainage requirements and permits.
  • Prepare preliminary plat and final plat with surveying, easements, and certificate blocks for approval and recordation.
  • Inspections during public improvements construction and documentation for acceptance by the city.

How-To

  1. Confirm zoning, minimum lot sizes and frontage requirements with DMD during a pre-application meeting.
  2. Prepare preliminary plat, site plans and engineered street/drainage plans to meet DPW standards and submit to DMD.
  3. Address review comments, obtain any required permits, and schedule inspections for required public improvements.
  4. Construct public improvements under inspection; secure surety or performance guarantees if required.
