Full Breakdown
The City of Seminole regulates accessory dwellings under its Land Development Code. Detached structures typically may not contain a second kitchen or be used as separate residences in single-family R-1 and R-2 districts. Florida's 2024 'Live Local Act' encourages ADU expansion, but local zoning still controls placement, setbacks, height, and owner-occupancy. Property owners considering an ADU should consult the Planning and Zoning Division before construction. Any habitable accessory building must meet Florida Building Code standards, connect to municipal utilities, and obtain a building permit. Short-term rental of an ADU is further limited by FS 509.032 preemption.
Violations & Fines
Unpermitted ADUs may face stop-work orders, fines up to $250 per day, mandatory removal, and code enforcement liens against the property.
