Lauderhill, FL Accessory Structures: ADU Rules (2026)

Section 5.1.8 of the Lauderhill Land Development Regulations defines an accessory dwelling unit as a secondary living unit with its own kitchen, bathroom, and sleeping area, existing within the same structure or on the same lot as a one-family dwelling. The standards in Section 5.1.8.B permit only one ADU per lot, and only as an accessory to a single-family dwelling, never to a two-family, multi-family, or mobile home use, and the unit cannot encroach on any required setback for the principal structure. An ADU may be attached, in which case it needs an operative interconnecting door and access only from the side or rear yard, or it may be a detached structure such as an apartment above a garage or a guesthouse; a mobile home or recreational vehicle cannot serve as an ADU.

Floor area must fall between 400 and 500 square feet, and the property must provide one or two off-street parking spaces for the ADU on top of what the principal dwelling already requires. ADUs must meet Schedule M minimum housing quality standards, including a certificate of use and annual inspections, and must satisfy Florida Building Code occupancy standards for bedroom size and ceiling height. For density purposes an ADU counts as half a dwelling unit unless it is affordability-restricted under Florida Statutes Section 163.31771.
