ADU rules in Marion County, IN — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
ADUs are permitted in most Indianapolis-Marion County residential zones under the Consolidated Zoning Ordinance. Must be secondary to the primary dwelling; subject to setbacks, height limits, and design standards. No statewide IN ADU mandate — fully local. Permits required from DBNS.
Indianapolis-Marion County allows ADUs in most residential zones per the updated zoning code (2024 revisions). External design must blend with primary dwelling. Height, materials, and exterior features may be restricted for visual harmony. No owner-occupancy requirement stated in current code. Variances available through Board of Zoning Appeals for non-standard configurations. Contact Dept. of Metropolitan Development for zone-specific rules.
Unpermitted ADU: standard building code enforcement. Zoning violation: cease-and-desist + fines. Must bring to code or remove.
