Unincorporated Franklin County, Florida requires a building permit for projects over $1,000 or 100 square feet, and every project in a special flood hazard area needs a permit1. The county also enforces zoning on land and water outside its municipalities2. A home using septic needs a current septic permit or an existing-system letter before the residential building application is complete3.

Do you need a building permit in Franklin County, Florida?
Yes. Franklin County requires a permit for projects over $1,000 or 100 square feet, while every project in a special flood hazard area requires a permit regardless of those thresholds1. The Franklin County Building Department reviews construction plans, issues permits, performs construction inspections and investigates code complaints for unincorporated Franklin County, including St. George Island, Eastpoint and Alligator Point9. Franklin County follows the current Florida Building Code, while the statewide base code is the Florida Building Code, 8th Edition (2023), as updated by the Florida Building Commission1011. Permitted residential work requires the applicant to schedule every required inspection at the proper stage12. Florida's agricultural exemption can cover a nonresidential farm building on bona fide agricultural land, but it does not cover a residence and does not displace floodplain-management rules13.
Who handles Franklin County building permits, zoning and flood review?
The Franklin County Building Department is the permit and inspection office for unincorporated land; it is at 248 Hwy 98, Eastpoint, FL 32328 and can be reached at 850-653-9783 or [email protected]9. Franklin County Planning & Zoning answers parcel-zoning, land-use, setback and development-permit questions at 248 US Highway 98 in Eastpoint, by phone at 850-653-9783 or by email at [email protected]6. Floodplain administration sits within the Building Department at the same Eastpoint office14. The county's published residential application will not accept an incomplete submission and calls for a complete application, building plans, boundary survey, site plan, energy-code form, water-and-sewer documentation, applicable septic documentation, and contractor or owner-builder paperwork15. Current county materials do not establish a county-road driveway permit, so ask Planning & Zoning which road authority controls access before designing the entrance6.
Does Franklin County, Florida have zoning?
Franklin County controls zoning for all land and water within the county's unincorporated limits; incorporated municipalities may administer their own rules2. Minimum lot size depends on the district: examples include 40 acres in the A-2 district with a one-acre residential lot, one acre in R-1, and one dwelling per 14,000 square feet in R-1A16. Setbacks also vary by district, although a recurring residential standard is 25 feet from a property line bordering a private, local arterial or collector road and 10 feet from another property line17. Dwelling-size rules are not one countywide number: the code sets different standards by housing type and district, including a 450-square-foot living-area threshold in the mobile-home definition and separate multifamily minimums18. Confirm the parcel's district with Planning & Zoning before using any example as the design standard for a particular lot6.
How do septic permits work in Franklin County?
A Franklin County residential application using a new or existing septic system must include a current septic permit or an existing-system letter3. Florida requires a permit to construct, install, modify, abandon or repair an onsite sewage treatment and disposal system, and the process includes a site evaluation for suitability19. DEP currently handles onsite sewage permitting in Northwest Florida, and Franklin County falls within DEP's Northwest District2021. Only about 0.4% of Franklin County soils are rated without severe limitations for a conventional septic drain field, so make the site evaluation an early purchase contingency rather than assuming a standard system will fit8. If an available public sewer reaches a property with a functioning onsite system, Florida generally requires connection within 365 days after written notice, subject to the law's conditions and possible waiver process22.
Can you live in an RV or tiny home on land in Franklin County?
We could not confirm a Franklin County rule that allows long-term residential RV occupancy or temporary camping on private land, so ask Planning & Zoning about the parcel and intended duration before buying or moving an RV onsite6. Florida's rules for transient guests in permitted recreational vehicle parks do not answer whether someone may live in an RV on an individual private parcel23. Tiny-home occupancy is also not confirmed by the reviewed county rules, and Franklin County zoning standards vary by housing type and zoning district18. A qualifying off-site-constructed dwelling must be allowed in a zoning district where a single-family detached dwelling is allowed, but the home still must satisfy generally applicable permitting, installation, health, utility, setback, height and bulk requirements24. Ask Planning & Zoning to confirm the parcel's district and allowed dwelling type before ordering a tiny or manufactured home6.
Building a home in Franklin County: the steps, in order
- Ask Planning & Zoning to identify the parcel's district, allowed residential use, lot standard and setbacks61617.
- Determine whether public water and sewer are available; a septic-served home needs current septic documentation with its building application3.
- If septic is needed, begin the DEP permit and site-evaluation process before fixing the house location1921.
- Assemble the county's residential submittal, including plans, survey, site plan, energy form and utility documentation; incomplete applications are not accepted15.
- If acting as your own contractor, include the owner-builder affidavit required for that arrangement5.
- Submit to the Building Department and obtain the permit before work that crosses the county's cost or area threshold, or before any work in a special flood hazard area19.
- Schedule the required inspections at the proper construction stages12.
What should you check before buying land in Franklin County?
Start with zoning, flood exposure, legal access, water service and septic feasibility, because those items determine where and what you can build213. Septic deserves special attention: only about 0.4% of county soils are rated without severe limitations for a conventional drain field8. The terrain is broadly gentle, with about 99.5% of land at a 15% slope or less, but flat coastal ground can still present drainage and flood-design constraints2526. Franklin County averages about 56.5 inches of precipitation a year, and about 58.9% of its land is wooded2728. The effective property-tax rate is about 0.6%, with a median annual bill of about $1,5722930. For a private well, Florida requires a permit from the appropriate water-management district or delegated authority before construction, repair or abandonment7.
Watch-outs
- Every project in a special flood hazard area requires a Franklin County permit, even when its cost and size fall below the ordinary permit thresholds1.
- A county owner-builder affidavit addresses who acts as contractor; it does not remove the building-permit requirement51.
- Private-land RV living, temporary camping and tiny-home occupancy remain unconfirmed; get a parcel-specific answer from Franklin County Planning & Zoning before purchase6.
- Conventional septic suitability is unusually constrained, with only about 0.4% of county soils rated without severe drain-field limitations8.
