Accessory Dwelling Unit (ADU) Permits in South Florida

Building an accessory dwelling unit — a guest house, garage apartment, or in-law suite with its own living space — in South Florida is a full permitted construction project involving building, structural, mechanical, electrical, and plumbing review, plus close attention to zoning. Across Miami-Dade, Broward, and Palm Beach counties, whether and how an ADU can be built depends heavily on local zoning. Endless Life Design files ADU permits and manages the build.

1. When an ADU Permit Is Required

An ADU is habitable space, so it requires a full set of permits across the trades, just like a primary dwelling. Converting existing space or building new both qualify. The building department reviews the entire project before issuing the permit.

An unpermitted ADU is a serious liability at resale and with code enforcement. Endless Life Design builds it correctly so it adds real value; reach the team at (305) 680-3283.

2. Zoning: The First Question

Before design, zoning determines whether an ADU is allowed on the parcel, its maximum size, setbacks, height, and parking requirements. These rules vary significantly across South Florida cities and districts, and the answer shapes the entire project. Confirming zoning first is essential.

3. Multi-Trade Construction and the HVHZ

An ADU involves structure, mechanical, electrical, and plumbing, all to current code, and in Miami-Dade and Broward's High-Velocity Hurricane Zone, enhanced structural and product-approval standards apply. New windows and doors must resist wind-borne debris. The project is coordinated across every trade.

4. Inspections and the Certificate of Occupancy

An ADU is inspected in phases through to finals across the trades, and a certificate of occupancy is issued once it is complete and compliant — the document that makes it lawfully habitable. Endless Life Design manages the inspection sequence to that finish line.
