Do I need a permit for water heater replacement in St. Petersburg?
Yes. In Florida, water heater replacement generally requires a permit, and St. Petersburg is no exception.
Whether a water heater swap needs a permit depends on your jurisdiction and the unit. Some jurisdictions exempt a small like-for-like electric replacement, while others require a plumbing permit for any change-out. Any gas water heater, any increase in size or wattage, or any relocation triggers a plumbing or gas permit almost everywhere.

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.
