Garage conversion rules in Osceola County, FL — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Converting a garage into living space in unincorporated Osceola County is treated as an accessory living unit or added habitable area — it needs a building permit, must meet the Florida Building Code, and if it becomes a separate dwelling it is capped at one ALU per lot.
The Land Development Code does not have a stand-alone 'garage conversion' section; a converted garage that becomes a second living unit is regulated as an Accessory Living Unit (LDC Sec. 3.6.1) — one per conforming lot, size-capped, and rentable only long-term with a homestead exemption. Where a garage is removed, the LDC requires a minimum of 40 square feet of enclosed storage so residents can store bulky personal effects. Any conversion needs a building permit and must satisfy Florida Building Code egress, electrical and light/ventilation standards. Inside Kissimmee or St. Cloud, city zoning controls.
An unpermitted garage conversion is a building and zoning violation; Osceola County Code Enforcement can require permits, correction, or reversal, with penalties under Chapter 7.
