Do You Need a Permit?
Permit RequiredA building permit is generally required for AC/HVAC change-outs, alterations, and new installations in the City of West Palm Beach. Florida's 2026 HB 803 small-project exemption does not apply to mechanical work, regardless of cost. A same-size equipment change-out with no ductwork or electrical changes may qualify for the city's simpler 'A/C Changeout' permit type; other mechanical work uses the city's general mechanical permit process, which may include an electrical sub-permit when the work changes electrical load or wiring.
