Unincorporated Liberty County, Florida requires a building permit for new construction, and the county's Building Services Division issues permits and inspects permitted projects12. A Planning & Zoning permit comes first for any new structure, including a mobile home, shed or pole barn3. Florida DEP, rather than a county health department, issues Liberty County septic permits45. Owner-builders may use the county's dedicated affidavit, but still need the applicable permits6.

Do you need a building permit in Liberty County, Florida?
Unincorporated Liberty County, Florida requires a building permit for new construction, and the county's Building Department reviews plans and issues permits714. The division also inspects permitted construction projects, although the reviewed rule does not list every inspection stage or exemption15. County permitting and inspection services cover Hosford, Lake Mystic, Telogia, Estiffanulga and Sumatra14. The statewide base is the Florida Building Code, 8th Edition (2023), as updated by the Florida Building Commission16. Liberty County's 2026 fee schedule charges $0.75 per square foot for a residential building permit plus a $100 residential plan-review fee, and doubles the fee when work starts before the permit is pulled17. The county has not published a complete list showing whether every category of alteration, repair or accessory project needs a permit, so ask the Building Department about the exact scope of work15. A separate Planning & Zoning permit is required before any additional property permit3.
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) 643-2215143. 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 Bristol14. To apply for the Planning & Zoning permit, bring a copy of the deed naming you as grantee and a site map of the parcel, either to the Building Department or through the online portal18. 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 directly19.
Does Liberty County have zoning?
The Liberty County Land Development Code applies to all land in the unincorporated areas of Liberty County, and development requires prior authorization under it20. A Planning & Zoning permit is necessary before constructing or placing a new home, mobile home, shed or pole barn83. Obtain that permit before applying for any additional property permits3. Lot coverage depends on the applicable land-use district and proposed use rather than one countywide percentage: the reviewed code caps nonresidential coverage at 65% in Town Center, Rural Village and Mixed Use-Rural Residential districts, and 50% in Mixed Use-Suburban/Residential districts21. The county's land-use districts include Conservation, Industrial, Town Center, Rural Village, Mixed Use-Suburban/Residential and Mixed Use-Rural Residential, each with its own standards22. For subdivision lots, the code sets a minimum lot size of 10,000 square feet for a single-family dwelling23. The code's Schedule 1.0 sets building setbacks by use: for low-density residential, a house must sit 20 feet from the front line, 20 feet from a corner-side line, 5 feet from the side lines and 20 feet from the rear line, and the medium-to-high-density residential figures are the same24. Industrial, commercial and office uses need 10 feet on the side24. Other code provisions, subdivision standards and floodplain rules may add to these, so ask Planning & Zoning to identify the parcel's district and applicable layout standards before designing the site25.
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 departments45. 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 mail5. Statewide, Florida law requires this kind of permit before a new onsite sewage system is installed anywhere a system doesn't already exist26. 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 exception10.
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 land2728. 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 inspection9. 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 conditions38.
Building a home in Liberty County: the steps, in order
- Call Liberty County Planning & Zoning at (850) 643-2215 to identify the land-use district, confirm the proposed home and site layout, and obtain the permit required before other property permits3.
- Apply for the building permit at 10818 NW SR 20, Bristol, or through the county portal14.
- If acting as your own contractor, file the county's Owner/Builder affidavit; it covers a one- or two-family residence or farm outbuilding built for your own occupancy, requires direct onsite supervision, and sale or lease within one year creates a presumption the exemption was violated29.
- Apply to Florida DEP for the septic permit with form DEP4015, a site plan, the floor plan, and a soil and topography site evaluation5.
- Schedule the Building Services Division's required inspections for the permitted construction15.
- Ask Road and Bridge about any county-road grading or culvert work at (850) 643-404019.
What to check before you buy land in Liberty County, Florida
About 51.5% of Liberty County is federal land, so verify a tract's boundaries and legal access before buying11. Liberty County is sparsely settled, with about 9.2 people per square mile and roughly 7,706 residents; the nearest city of 100,000 or more is about 41 miles from the county center303132. About 98% of the land has a slope of 15% or less, but only about 0.6% of county soils are rated without severe limits for a conventional septic drain field3310. Get the required septic site evaluation before committing to a house location5. If any part of the parcel lies in a flood hazard area, a floodplain development permit from the Floodplain Administrator is required before building, even for buildings exempt from the Florida Building Code34. The county's flood amendments set the minimum elevation for flood-area construction at the base flood elevation plus 2 feet, or the design flood elevation if higher35. Dividing land also needs county approval: a division into no more than 15 parcels of 10 acres or more can skip plat review but still requires Board approval36. Also confirm the land-use district and lot-coverage standard with Planning & Zoning, because the code's caps vary by district and use21. The effective property-tax rate is about 0.9%, with a median annual bill near $1,0311213.
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 file45.
- The county's own pages don't publish a minimum lot size for non-subdivision parcels or an RV/tiny-home occupancy rule; confirm those specifics with Planning & Zoning for your exact parcel rather than assuming3.
