ADU Permit Steps for Homeowners in Baton Rouge
In Baton Rouge, Louisiana, homeowners who want to add an accessory dwelling unit (ADU) must follow local zoning and building-permit procedures before construction or occupancy. This guide explains typical permit steps, responsible departments, application forms, inspections, timelines, and enforcement pathways under Baton Rouge municipal rules to help you plan and comply.
Pre-application and Zoning Check
Start by confirming that your property zoning allows an ADU and whether lot size, parking, height, and setback standards apply. Contact the local planning office for zoning verification and request any pre-application guidance or a zoning compliance letter. See the municipal code and planning department for definitions and allowable accessory uses municipal code[1].
Design, Plans, and Professional Requirements
Prepare construction drawings sized to the permit office’s requirements. Larger ADUs or those with structural, electrical, or plumbing work usually require licensed professionals (engineers or architects) to seal plans. Confirm plan submission standards with Developmental Services or Planning prior to filing.
Permit Application & Submission
- Complete the building permit application and include site plan, floor plans, elevations, and utility information; submit to the permit center for review Building Permits & Inspections[3].
- Pay review and permit fees at time of submission; fee schedules appear on the permit office page or are provided upon intake.
- Expect an intake review for completeness, followed by technical reviews (zoning, structural, electrical, plumbing, fire).
Review, Revisions, and Approvals
The permit office circulates plans to reviewers and returns comments requiring revisions. Respond promptly with corrected drawings and documentation. Once technical compliance is confirmed and fees paid, the permit is issued and work may begin per the issued permit conditions. For clarification on review roles and submission process consult the planning division and permit center resources Planning Division[2].
