Still requires a permit
Does Florida’s new $7,500 permit exemption apply to hvac / mechanical permits in Osceola County?
No. HB 803 names mechanical work as an explicit exclusion from the $7,500 exemption, so an HVAC or mechanical permit is still required even on a small change-out.
HB 803 (Chapter 2026-63) took effect July 1, 2026 and applies statewide, including Osceola 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 an HVAC / mechanical permit cost in Osceola County?
HVAC / Mechanical Permit fees in Osceola County generally fall in the $100-300 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.
