Still requires a permit
Does Florida’s new $7,500 permit exemption apply to water heater permits in Martin County?
No. A water heater replacement is plumbing work, and usually gas or electrical work as well, all of which HB 803 excludes from the $7,500 exemption. A permit is still required.
HB 803 (Chapter 2026-63) took effect July 1, 2026 and applies statewide, including Martin County. To qualify, all of the following must be true:
- The property is a single-family residential property
- The total value of the work is less than $7,500, based on a written proposal or estimate from a licensed contractor
- The property is not in a flood hazard area
- The work is not electrical, plumbing, mechanical, gas, or structural work
The exemption is not self-certifying. A homeowner or contractor submits an exemption request and the building official determines whether the work qualifies. Starting work on the assumption that it does can lead to a stop-work order and an unpermitted-work disclosure when you sell.

How much does a water heater permit cost in Martin County?
Water Heater Permit fees in Martin County generally fall in the $50-150 range. Florida counties set their own fee schedules and most calculate them from the declared job valuation, so the final figure depends on the size of your project.

Do I need a Notice of Commencement for a water heater permit in Martin County?

Often yes.
