Setback requirements match those for accessory structures (typically 5 feet from side and rear property lines). Owner occupancy of either the primary or accessory unit may be required. ADUs must meet current building code, include independent kitchen and bathroom facilities, and comply with county utility connection requirements. Florida state legislation may further shape local ADU rules.
