Garage conversion rules in Pinellas County, FL — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Pinellas County requires building permits and zoning review for converting a garage to living space under Chapter 22 Housing Code and Land Development Code parking and density standards.
Garage-to-living-space conversions in unincorporated Pinellas County must be permitted through the Building Department and reviewed against the Land Development Code. Converted floor area counts toward overall density and may trigger ADU rules under Sec. 138-3210 if it adds a separate kitchen and bathroom. Sec. 138-3220 outdoor storage standards and the off-street parking requirements in Chapter 138 must still be satisfied, meaning lost garage parking usually has to be replaced on the lot. Chapter 22 Housing Code sets minimum habitable room size, ceiling height, light, ventilation, and egress for converted spaces. Florida Building Code wind, energy, and electrical standards apply at permit review.
Unpermitted garage conversions can trigger code enforcement, daily fines, mandatory permit-after-the-fact, and removal of unapproved kitchens or bedrooms that fail housing or zoning standards.
