Still requires a permit
Does Florida’s new $7,500 permit exemption apply to room addition permits in Polk County?
No. A room addition is structural work and will also exceed $7,500 in nearly every case, so both of HB 803's limits rule it out. A permit is still required.
HB 803 (Chapter 2026-63) took effect July 1, 2026 and applies statewide, including Polk 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 room addition permit cost in Polk County?
Polk County charges $85.00 for room addition permits, listed on its fee schedule as “Building Permit — residential, valuation up to $12,000”. Additions are billed off the residential valuation table, so a typical addition sits far above the first tier. New single-family construction is instead a combined $0.30 per square foot under roof covering building, plumbing, electrical and a/c. This is the county’s permit fee only — it does not include your contractor’s price for the work.
