#6 of 67 in Florida

Unincorporated Calhoun County, Florida requires a development/building permit before construction begins, issued by the county's Building Department once the project conforms to the applicable zoning district12. Septic permits go through the Florida Department of Environmental Protection directly rather than through the county, since Calhoun is one of the counties whose onsite sewage program transferred from the county health department to FDEP effective January 2, 20253. An owner-builder exemption lets you pull your own permit for a home you plan to live in, as long as you sign the state's disclosure statement4.

Do you need a building permit in Calhoun County, Florida?

Yes. Calhoun County's Land Development Code requires an appropriate permit or certificate before construction begins anywhere in the county's unincorporated planning jurisdiction, which covers the entire unincorporated area18. Construction, alteration, repair, moving, demolition, occupancy changes, and regulated trade work in Calhoun County are subject to the Florida Building Code, 8th Edition (2023), which applies statewide without separate local adoption9. Florida counties get authority from state law to enforce the Florida Building Code and issue permits for construction in unincorporated areas10. If you'll act as your own contractor on a one- or two-family home for your own occupancy, Florida's owner-builder exemption lets you sign for the permit yourself, and it also covers a farm outbuilding or a commercial building up to $75,000 in cost, as long as you don't sell or lease the finished home within a year411.

Who is the Calhoun County building department, and how do you reach them?

Calhoun County's Building Department handles permits, inspections, and certificates of occupancy from the county administration building at 20867 SE Fannin Ave. in Blountstown; call (850) 674-804612. Its online forms cover everything from a standard residential permit to a driveway/culvert permit, an RV power pole application, and manufactured, HUD modular, and FBC modular home applications12. Zoning and land-use questions go to the Planning Department at the same address, (850) 451-5873, which keeps its own RV application form and reviews whether a project fits the parcel's land-use district132.

Does Calhoun County have zoning?

Yes, Calhoun County's Land Development Code covers the entire unincorporated county, dividing it into land-use districts including Residential (R), Mixed Residential-Recreational (M-RR), Mixed Urban Fringe (M-UF), Industrial (I), Agricultural (A), Rural Open (R-O), Commercial (C), Planned Unit Development (PUD), Public (P), Historic (H), and Water (W)214. Density limits vary sharply by district: the R district allows up to 2 units per acre, the Agricultural (A) district allows only 1 unit per 10 acres, and the M-UF district ranges from 2 units per acre up to 8 units per acre depending on whether central water and sewer serve the site15. Florida law gives counties the general power to establish and enforce zoning, and Calhoun's official Future Land Use Map is what actually divides the unincorporated county into these districts1617. For your specific parcel's allowed uses and setbacks, confirm the district against the Planning Department's Land Use Map before you buy13.

How do septic permits work in Calhoun County?

Septic permitting in Calhoun County goes through the Florida Department of Environmental Protection directly, not through the county government, because Calhoun is one of the Northwest Florida counties FDEP took over from the county health department in a transition that began January 2, 2025318. Statewide, anyone installing, replacing, repairing, or abandoning an onsite sewage treatment and disposal system needs a permit and a site evaluation before construction19. That evaluation carries real weight here: only about 5% of Calhoun County's soils have no severe limitations for a conventional septic drain field, so budget for the likelihood of an engineered or alternative system rather than a standard drain field20. This guide could not confirm a separate Calhoun County septic-inspection requirement beyond FDEP's own permitting and site-evaluation process, so ask FDEP directly what your project will need3.

Can you live in an RV or tiny home on your land in Calhoun County?

Calhoun County has its own RV permit application covering placement on unincorporated land: it allows one RV per non-subdivided parcel, sets density and setback rules, requires two parking spaces, and caps impervious surface for the RV and its accessories at 30%5. If the parcel is in a mapped floodplain, the RV can only stay fewer than 180 consecutive days at a time, must stay on wheels or jacks with quick-disconnect utilities, and can't have permanent attachments5. Florida's statewide rules for recreational vehicle parks and recreational camps only cover permitted, transient-guest parks and camps holding a Florida Department of Health permit, so they don't substitute for Calhoun's own RV permit on private land2122. This guide could not confirm a specific Calhoun County rule on tiny-home occupancy, so bring your plans to the Planning and Building Departments before you buy1312. A manufactured home has its own defined path: state law requires an onsite inspection for compliance with statewide installation standards, and a certificate of occupancy follows once the home passes, though local zoning and the Building Department's own manufactured-home application still apply712.

Building a home in Calhoun County: the steps, in order

  1. Contact the Planning Department to confirm your parcel's land-use district and what it allows before you design anything132.
  2. Line up your Environmental Health (FDEP) onsite sewage site evaluation and permit early, since most of the county's soils need more than a standard drain field320.
  3. Decide whether to build as an owner-builder, signing the state's disclosure statement, or hire a licensed contractor4.
  4. Submit your building permit application to the Building Department once your plans meet the Florida Building Code, 8th Edition (2023)129.
  5. Call for each inspection at least 24 hours ahead as work progresses, from slab/footer through framing, roof, rough mechanical-electrical-plumbing, insulation, drywall, and final23.
  6. Apply to the Building Inspector for your Certificate of Occupancy once the completed work passes inspection and conforms to your permit6.

What to check before you buy land in Calhoun County

Confirm the parcel's zoning district and density limit before you buy: an Agricultural (A) parcel allows only 1 unit per 10 acres, while some Mixed Urban Fringe (M-UF) parcels allow up to 8 units per acre if central water and sewer are available15. Get the soil evaluated for septic suitability early, since only about 5% of Calhoun County's soils carry no severe limitations for a conventional drain field20. This guide could not confirm a Calhoun County private-well permitting requirement, so ask the Building Department what applies to your parcel before you count on a well12. The county is largely gentle and wooded terrain, with 100% of land at 15% slope or less and 65.7% forest cover, which generally favors building sites2425. Property tax runs low here, with an effective rate near 0.6% and a median annual bill around $7432627.

Watch-outs

  • Septic permitting moved from the county health department to the Florida Department of Environmental Protection on January 2, 2025; don't call the county expecting to handle septic there3.
  • Density and allowed uses vary sharply by zoning district in Calhoun County, from 1 unit per 10 acres in the Agricultural district up to 8 units per acre in parts of the Mixed Urban Fringe district, so confirm your parcel's district before assuming what you can build15.
  • Only about 5% of Calhoun County's soils have no severe limitations for a conventional septic drain field; get a site evaluation before you count on a standard system20.
  • This guide could not confirm Calhoun County rules on tiny-home occupancy, general temporary camping outside the RV permit process, agricultural-building exemptions, short-term rentals, or private-well permitting; ask the Planning and Building Departments directly about each before you rely on an assumption1312.
