Osceola County driveway permits
In unincorporated Osceola County, which takes in Harmony, Narcoossee, Ashton and Holopaw, two short paragraphs of the county code govern driveways. Section 22-50.6 reads: "(a) Residential driveways shall not exceed twenty-four (24) feet in width unless approved by conditional use. (b) Residential driveway construction or widening shall be authorized by the issuance of a driveway permit by Osceola County."
That makes widening a driveway a permitted job in its own right, and the 24 foot cap is the number that decides how wide a driveway extension can be at the street.
The apron, sidewalks and culverts

Slabs, sheds and the building office
The county Building Office's list of residential work that needs a permit includes a slab with footers, a shed or storage building, a pool and pool screen enclosure, a screen room and a pergola. The fee appendix (Resolution 24-062R, effective October 1, 2024) sets these lines:
| Item | Fee |
|---|---|
| Slab with footer | $60 plan review + $60 permit |
| Residential slab permit review, zoning (adding a slab to a developed site) | $20 flat |
| Failure to obtain a permit before work begins | $80 + double the normal permit fee |
Source: Osceola County Appendix A, Building Permit and Related Fees, effective October 1, 2024. Building Office: 1 Courthouse Square, Suite 1400, Kissimmee; 407-742-0200.
A detached garage or barn slab is part of that building's permit; the concrete slab page covers the termite treatment and vapor retarder that go with it.
The $7,500 exemption in the county
Osceola County's permit page says that from July 2026 it implements the building permit exemption from HB 803, the 2026 law behind Section 553.79(1)(g). Excluded: structural, electrical, plumbing, mechanical and gas work, and work on properties partly or entirely in a flood hazard area. Requests go to the Building Office on its Owner Disclosure of Exempt Work form. The exemption covers building permits only; a driveway permit under Section 22-50.6 is a separate requirement.
Driveways onto US 192 and US 441
Rural lots east of St. Cloud often front a state highway. A driveway connecting to one needs a connection permit from the Florida Department of Transportation: Rule 14-96.003 says no one may construct, relocate or alter a connection without first obtaining one, regardless of other governmental permits. The Holopaw page covers the rural-lot details.
