Summary
Unincorporated Palm Beach County lets you convert a garage or carport to living space, but only if you replace the lost parking in the driveway or a common lot first.
Space within a carport or garage may be used to satisfy residential parking requirements, provided that no Building Permit shall be issued to convert a carport or garage to a living area without a provision to provide the required parking spaces in the driveway or in a common parking lot.
Full Breakdown
The ULDC allows counting a carport or garage toward a home's required parking, but that credit disappears the moment you convert the space to living area. Building Division will not issue a permit for the conversion unless the site plan shows replacement parking added in the driveway or a common parking lot equal to what the garage or carport used to provide. This applies in unincorporated Palm Beach County only. Boca Raton, Delray Beach, Boynton Beach, West Palm Beach, Jupiter and the county's other 34 municipalities set their own rules under their own codes.
Violations & Fines
Converting a garage or carport without first providing the replacement parking blocks permit issuance outright: the county will not sign off on the conversion, and work done without the permit is subject to the standard unpermitted-construction enforcement process under the ULDC.
