Summary
Port St. Lucie sets a minimum house size in every residential district, so a very small dwelling will not qualify as a stand-alone home, and the code separately bans living in a recreational vehicle.
(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
The city has no tiny-home ordinance. What controls is the minimum living area written into each residential zoning district. In the RS-2 district, Sec. 158.073(G) requires a one-story house of at least 1,200 square feet of living area with 1,400 square feet of ground area, or 1,400 square feet of living area for a two-story house. The RE and RS-1 districts require 1,700 square feet. A house permitted before June 7, 1996 with less than 1,200 square feet may be rebuilt at its approved size. Sec. 158.042 also allows only one principal building per lot, so a tiny house cannot simply be added beside an existing home.
Violations & Fines
A dwelling below the district minimum, or a second principal structure on a single-family lot, is a zoning violation punished under Sec. 158.999 and the general penalty in Sec. 10.99, with each day a separate offense.
