ADU rules in Baton Rouge, LA — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Baton Rouge permits ADUs in certain zoning districts (A1 and A2) under the UDC. ADU allowances are more limited than in states like California. Recent UDC updates are gradually expanding ADU options.
In Baton Rouge and East Baton Rouge Parish, ADUs are permitted in A1 and A2 zoning districts under the Unified Development Code. However, they have historically been restricted, sometimes limited to family members or domestic employees unless special approvals are obtained. Recent UDC amendments are gradually opening doors for more rental ADU options. Properties must meet minimum lot size requirements to support a second dwelling unit. Building permits are required for all ADU construction. Louisiana does not have a statewide ADU mandate like California's. The Department of Development reviews ADU applications.
Unpermitted ADUs face code enforcement action. ADUs in non-qualifying zoning districts are zoning violations.
