Do I need a permit for standby generator installation in St. Petersburg?
Yes. In Florida, standby generator installation generally requires a permit, and St. Petersburg is no exception.
A permanently installed standby generator requires an electrical permit for the transfer switch, plus a gas or fuel permit for natural gas or propane connections, and often a building or structural review because the unit must be anchored for wind uplift. Portable generators are not permitted work, but any hard-wired or fuel-connected unit is. Propane tanks have separate siting rules.
Local and county notes for St. Petersburg
Requirements are multi-agency and can include zoning, fire, and environmental review for fuel tanks. Signed and sealed plans and wind-load anchoring are often required. A permanently installed standby generator involves electrical work (and gas piping for fueled units), so St. Petersburg requires a permit; the HB 803 $7,500 exemption never covers electrical or gas work. Generator placement must meet St. Petersburg zoning setbacks and manufacturer clearances; show the unit and its clearances on a site plan. In the Special Flood Hazard Area the generator and fuel supply should sit above the base flood elevation; confirm floodplain requirements with the city before installing. Pinellas County's own permitting office is the Building and Development Review Services Department, reachable on (727) 464-3888 at https://pinellas.gov/applying-for-a-building-permit/. Its online permit portal is https://aca-prod.accela.com/pinellas/default.aspx. It issues permits for the unincorporated county. If your city does not run its own building department, this is the office that will handle the job. Contractor licensing here is countywide, which is unusual. The Pinellas County Construction Licensing Board, established in 1973, regulates construction and home improvement contractors practicing in Pinellas County including all local municipalities, so whoever you hire needs to be licensed through it no matter which city you are in. Reach it on (727) 582-3100 or pcclb@pinellas.gov, 440 Court St, 1st Floor, Clearwater. State legislation has been changing which specialty trades are licensed locally rather than by the state, so confirm the current licence type your trade needs before signing a contract.
