Summary
Port St. Lucie requires every single-family home to have a garage or carport of at least 200 square feet at certificate of occupancy, so converting one to living space runs against Section 158.206.
(1)(a) As provided in this subsection, it shall be unlawful for any person, firm, corporation, or governmental entity to construct, erect, alter, modify, repair, or demolish any building within this state without first obtaining a permit therefor from the appropriate enforcing agency or from such persons as may, by appropriate resolution or regulation of the authorized state or local enforcing agency, be delegated authority to issue such permits, upon the payment of such reasonable fees adopted by the enforcing agency.
Full Breakdown
Section 158.206 says each single-family residence shall have either a garage or a carport containing a minimum of 200 square feet, plus an enclosed storage area of at least 80 square feet, at the time the certificate of occupancy is issued. Section 158.221(A)(5) separately makes it unlawful to discontinue, change or reduce required parking without establishing alternative facilities, and 158.221(C)(8)a sets the exterior-space count: two spaces with a one-car garage, one with a two-car garage, two with no garage. Any conversion is also permit work. Section 150.001 adopts the Florida Building Code, 7th Edition (2020), whose Section 105.1 requires a permit to alter a building or change its occupancy or use.
