Some RestrictionsADU Permits
Fort Wayne permits Accessory Dwelling Units under Chapter 157 of the Fort Wayne Zoning Ordinance, administered jointly with Allen County by the Allen County Department of Planning Services (DPS). ADUs may be integrated (attached/within the principal dwelling) or freestanding (detached). DPS issues an ADU Administrative Permit at a $150 application fee, and the Allen County Building Department (ACBD) issues the building, electrical, plumbing, and mechanical permits under the Indiana Residential Code (675 IAC 14, adopting the 2018 IRC with Indiana amendments).

Some RestrictionsADU Impact Fees
Fort Wayne and Allen County do not levy a general residential impact fee on ADUs. Indiana Code 36-7-4-1300 (Impact Fee Act) authorizes local impact fees only after a formal Impact Fee Ordinance with a Zone Improvement Plan, which Fort Wayne has not adopted for residential construction. Costs for an ADU are limited to the $150 DPS zoning permit, ACBD building/electrical/plumbing/mechanical permit fees calculated by valuation, plus separate City Utilities tap and connection charges.

Few RestrictionsADU Owner Occupancy
Fort Wayne requires the property owner to occupy either the principal dwelling or the ADU as their primary residence when the other unit is rented. This owner-occupancy condition is enforced through the DPS Administrative ADU Permit and is consistent with Chapter 157 standards limiting ADUs to genuine accessory use. Indiana has no statewide ADU statute, so the local rule controls; HOA covenants may impose stricter limits independently.
