ADU rules in Broward County, FL — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Broward County permits accessory dwelling units in several zoning districts, typically capped at 800 square feet or 40 percent of the primary home, with owner-occupancy and one off-street parking space.
Broward County Code Chapter 39 (Zoning) permits accessory dwelling units (ADUs), also called guest houses or granny flats, on single-family parcels in most residential districts. Detached ADUs must sit behind the primary home, observe the same side and rear setbacks as accessory structures, and generally cannot exceed 800 square feet or 40 percent of the primary residence gross area, whichever is less. Attached ADUs, including garage conversions, follow the principal-structure setbacks. Owner occupancy of either unit is typically required, and one additional off-street parking space must be provided. ADUs must connect to the primary water and sewer service and cannot be sold separately. Broward sits in the HVHZ, so impact-rated windows and doors or code-approved shutters are mandatory.
