Homestead, FL Accessory Structures: ADU Rules (2026)

Homestead permits accessory dwelling units in certain residential zoning districts subject to the Land Development Code and Florida Building Code (HVHZ edition). ADUs can be attached to the primary dwelling (converted garage, addition) or detached structures on the same lot. ADUs must comply with all HVHZ building requirements including wind resistance, impact-resistant openings, and structural standards. Setbacks typically match those of the primary structure. ADUs must have separate utility connections or metered sub-connections. Florida's recent legislative changes, including the Live Local Act, encourage ADU development statewide and limit some local restrictions. However, Homestead may still require site plan review, owner occupancy of either the main dwelling or ADU, and parking for ADU residents. ADU size is typically limited to a percentage of the main dwelling's square footage or a maximum cap. Building permits, including structural, electrical, plumbing, and mechanical permits, are required. ADUs in flood zones must meet flood elevation requirements.
