Polk County, FL Swimming Pools & Spas: Fencing Requirements (2026)

Polk County does not impose a stricter local pool barrier height than state law; the Florida Residential Swimming Pool Safety Act (F.S. 515.21-515.37, sometimes called the Preston de Ibern/McKenzie Merriam Act) applies. F.S. 515.27 requires that all new residential swimming pools (including spas and hot tubs more than 24 inches deep) have at least one of the following safety features in place to pass final inspection: (1) a barrier complying with F.S. 515.29 - minimum 4 feet high on the outside, no gaps that allow a 4-inch sphere to pass through, with self-closing/self-latching gates that open outward and have the release mechanism on the pool side at least 54 inches above the ground; (2) an ASTM F1346 safety pool cover; (3) exit alarms with minimum 85 dB sound pressure rating at 10 feet on all doors and windows providing direct access from the home to the pool; (4) self-closing, self-latching devices on home doors with the release at least 54 inches above the floor; or (5) an ASTM F2208 pool alarm (wearable alarms do not satisfy this requirement). Pools constructed before October 1, 2000 are generally exempt unless the property is sold, in which case the buyer must comply within 90 days. Polk County permits residential pools through its Building Division under Chapter 4 of the Code of Ordinances and the Florida Building Code, Residential Volume, Section R4501. Pool safety inspections are part of the Certificate of Completion process. Polk County is not in a High Velocity Hurricane Zone (HVHZ), so the enhanced 170 mph wind-load requirements applicable to Miami-Dade and Broward do not apply.
