Unincorporated Liberty County, Florida requires a building permit for new construction, issued and inspected by the county's Building Services Division under the Florida Building Code1. The county also requires a Planning & Zoning permit before you place any new structure, including a mobile home, shed or pole barn, administered under contract by the Apalachee Regional Planning Council23. Septic is different here than in most Florida counties: since a 2021 program transfer, the Florida Department of Environmental Protection directly issues septic permits for Liberty County rather than a county health department4. An owner-builder affidavit lets you build your own home without hiring a licensed contractor, though the county's building and zoning permits are still required5.

Do you need a building permit in Liberty County, Florida?
Unincorporated Liberty County, Florida requires a building permit before you build, and the county's Building Department reviews plans, issues the permit, and inspects the work under the Florida Building Code112. That covers the unincorporated communities of Hosford, Lake Mystic, Telogia, Estiffanulga and Sumatra12. Florida counties generally have authority to enforce the Florida Building Code and adopt local technical amendments to it, and the state's base code for Liberty County is the Florida Building Code, 8th Edition (2023), as updated by the Florida Building Commission1314. A separate Planning & Zoning permit is required first, before you apply for the building permit itself3.
Who is the Liberty County building department, and how do you reach them?
The Building Department and the Planning & Zoning Department both run out of the same county office at 10818 NW SR 20, Bristol, Florida, and both are reached at (850) 643-2215123. You can apply for a building permit, manage an existing permit, or make a payment online through the county's permit portal rather than driving to Bristol12. Planning & Zoning is administered a little differently: the Board of County Commissioners has contracted that work out to the Apalachee Regional Planning Council, but you still file through the same county office and phone number3. For anything involving a driveway, culvert or grading onto a county road, call the separate Road and Bridge Department directly15.
Does Liberty County have zoning?
Liberty County does have zoning, administered as a Planning & Zoning permit rather than a traditional zoning-map lookup2. The county's own page is direct about when you need one: a permit is necessary when you intend to construct or place any new structure on your property, and that explicitly includes a new residential home, a mobile home, a shed, or a pole barn3. That Planning & Zoning permit has to be obtained before you apply for any additional permits related to the property, which makes it the first call to make, not an afterthought3. The county's page doesn't publish district-by-district setbacks or minimum lot sizes, so confirm those specifics with Planning & Zoning for your exact parcel before you plan a layout3.
How do septic permits work in Liberty County?
Septic works differently in Liberty County than in most of Florida: rather than the county health department, the Florida Department of Environmental Protection directly issues septic (OSTDS) permits here, one of a group of Panhandle counties where DEP took over the program from local health departments46. To apply, you submit the DEP4015 construction-permit application and site plan, a copy of your building floor plan, and a site evaluation of the property's soil and topography, either through DEP's online permit and service request portal or by mail6. Statewide, Florida law requires this kind of permit before a new onsite sewage system is installed anywhere a system doesn't already exist16. Plan for that site evaluation to matter: only about 0.6% of Liberty County's land is rated free of severe limits for a conventional septic drain field, so an engineered system is the likely outcome on most tracts rather than the exception8.
Can you live in an RV or tiny home on your land in Liberty County?
Liberty County's own pages don't publish a specific answer for putting an RV or tiny home on a private parcel, and Florida's statewide rules for recreational vehicles and camps only cover permitted RV parks and recreational camps, not living in an RV on your own land1718. A manufactured home is a more defined path: state law requires an onsite inspection for compliance with uniform installation standards, and a certificate of occupancy follows once the home passes that inspection7. Because Liberty County requires a Planning & Zoning permit before placing any new structure, including a mobile home, that office is where you find out whether your specific parcel allows an RV or tiny home as a residence and under what conditions32.
Building a home in Liberty County: the steps, in order
- Call Liberty County Planning & Zoning at (850) 643-2215 to confirm what your parcel allows and get your Planning & Zoning permit, which is required before any other permit3.
- Apply for your building permit with the Building Department, in person at 10818 NW SR 20, Bristol, or online through the county's permit portal12.
- If you're acting as your own contractor, file the Owner/Builder affidavit that the Building Department keeps on hand for that purpose5.
- Start your septic permit with the Florida Department of Environmental Protection rather than a county health department: submit form DEP4015, a site plan, your floor plan, and a soil and topography site evaluation through DEP's online portal6. Budget for an engineered system given how little of the county's soil is rated free of severe septic limits8.
- If your driveway needs dirt, grading or a culvert on a county road, call the Road and Bridge Department at (850) 643-4040 to arrange it15.
- Budget for property tax: Liberty County runs about a 0.9% effective rate, with a median bill near $1,031 a year1011.
What to check before you buy land in Liberty County, Florida
Federal land dominates Liberty County: about 51.5% of the county, mostly Apalachicola National Forest, so confirm your parcel's exact boundaries and access before you assume you can build where a map suggests9. This is genuinely rural land: about 9.2 people per square mile across a population of roughly 7,706, with the nearest metro area about 41 miles away192021. Terrain is easy to build on but wet and wooded: about 98% of the county sits at 15% slope or less and about 91% is wooded, with 57 inches of rain a year and severe drought in only about 8% of recent years22232425. Septic soils are the real constraint: only about 0.6% of the county's land is rated free of severe limits for a conventional drain field, so get a site evaluation before you commit to a specific tract8. Farmland has recently valued around $4,646 an acre and a typical home around $207,878, against a roughly 0.9% effective property tax rate and a median bill near $1,031 a year26271011.
Watch-outs
- Get your Planning & Zoning permit before anything else: Liberty County requires it before you apply for any additional permit, including the building permit itself3.
- Septic in Liberty County goes through the Florida Department of Environmental Protection, not a county health department; don't call the health department first and expect them to hold the file46.
- The county's own pages don't publish parcel-level setbacks, minimum lot sizes or an RV/tiny-home occupancy rule; confirm those specifics with Planning & Zoning for your exact parcel rather than assuming3.
