What makes the number move
- Tank versus tankless (tankless usually needs gas or electrical upgrades)
- Capacity in gallons and recovery rate
- Garage, attic or interior closet location
- Code upgrades: pan, drain line, expansion tank, seismic or hurricane strapping
- Removal and disposal of the old unit
How to pay less
- • Get three written bids — spread between local bids on this project is routinely 25% or more.
- • Schedule in the off-season; St. Petersburg contractors price peak demand higher.
- • Confirm the permit fee is itemized rather than marked up inside the labor line.
- • Verify the license at DBPR before paying a deposit; unlicensed work voids most claims.

Frequently asked questions
Do I need a permit to replace a water heater?
Yes. Florida jurisdictions require a plumbing permit for a water heater changeout because the work involves gas or electrical connections, temperature and pressure relief piping, and drainage. Replacing without a permit can cause insurance and resale problems.
Can I replace my own water heater?
A homeowner can pull an owner-builder permit and replace a water heater in a home they own and occupy. Electrical and gas connections must still pass inspection.
How long does a water heater last?
Standard tank units last 8-12 years; tankless units often reach 15-20 years with annual descaling. Florida's hard water shortens tank life in many areas.
