We keep that walkthrough in one place: how a water heater permit application and its inspections work, start to finish. What changes between Florida jurisdictions is below: who requires a permit, what they charge, and which office you file with.

What a water heater permit costs in Florida
3 Florida jurisdictions we cover publish a fee figure for this work. Each line is quoted from that office's own schedule and linked to its citation. The figures are not comparable to one another: some are flat minimums, some a percentage of job value, some charged per fixture, so what you pay depends on which schedule applies and on your job's valuation.
Fee schedule effective July 1, 2026: construction costs under $25,000 pay a $75 building fee, a $25 plan review fee and $75 per inspection; the HB 803 permit exemption waiver for qualifying work under $7,500 is $75.

"Plumbing (general) for all plumbing-related activities not addressed below or any other fee table" $120.00, City of Tampa Trade Permit Fee Schedule ("Effective October 1, 2018", "Updated 2/16/2023"), residential (one and two family dwellings) column; the post-hurricane guide pairs a plumbing trade permit with an electrical trade permit for a water heater change-out, so expect a separate electrical trade fee where wiring is involved. Every permit also carries the Florida Building Permit Surcharge of 2.5% of permit value or $4.00 minimum, not included in the listed fees.
