Licensing and permits
Plumbing work in Florida must be done by a certified or registered plumbing contractor licensed through Florida's Construction Industry Licensing Board. Repiping and water-heater replacements usually need a permit.
Tips before you hire
- Ask for a camera inspection before replacing a main drain line.
- If insurers flagged polybutylene or galvanized supply lines, get a repipe quote with the permit included.
- Tank water heaters in Florida often sit in garages. Make sure the replacement includes a pan and an expansion tank where code requires.

Frequently asked questions
Do I need a permit to replace a water heater in Florida?
In most Pinellas jurisdictions, yes. A licensed plumber or electrician pulls it.
Why do insurers ask about my plumbing?
Older supply lines (polybutylene, galvanized) and cast-iron drains are common water-damage claim sources, so they show up on 4-point inspections.
