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

Unincorporated Walton County requires a building permit for construction or alteration that requires a Building Division technical-code inspection81. Covered applications submitted after December 31, 2023 must be designed and built under the 2023 Florida Building Code18. Outside the Coastal Building Zone, the Building Department may exempt an owner-built, non-habitable structure of 400 square feet or less or an addition to living space of 100 square feet or less from certain building-permit requirements, but Planning consultation is still required9. Qualifying nonresidential farm buildings, farm fences and farm signs are exempt from the Florida Building Code and local code or fees, but not floodplain rules19. Walton County publishes building-permit fee schedules, but the amount depends on the project20. A separate Florida owner-builder pathway lets an owner directly supervise work on an owner-occupied one- or two-family home not offered for sale or lease; it does not eliminate applicable building permits or inspections21.

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

The Walton County Building Division handles building permits for unincorporated Walton County; call (850) 892-8160 or email permits@mywaltonfl.gov822. The Building Division office is at 117 E Sloss Ave in DeFuniak Springs and opens Monday through Friday, 8:00 a.m. to 4:30 p.m.22. Inside DeFuniak Springs, the city issues building permits, while Florida DEP remains the septic permitting authority46. For county zoning, development orders and floodplain questions, contact Walton County Planning and Development Services at (850) 267-1955, 842 State Highway 20 East, Unit 110, Freeport, FL 32439232.

Does Walton County have zoning, and what does that mean for your parcel?

Walton County zoning governs unincorporated land; DeFuniak Springs administers city zoning, while Florida DEP still handles septic permits there356. Walton County publishes a GIS zoning layer and district descriptions, but online code publication can lag amendments; confirm the current district rules with Planning before designing2423. County single-family setbacks generally are 20 feet front, 7.5 feet side and 15 feet rear, subject to buffers, scenic corridors, easements and other exceptions25. Impervious-surface limits vary by district, with several rural districts capped at 30%26. South Walton generally has a 50-foot height limit, reduced to 40 feet in Grayton Beach and 32 feet in Point Washington Neighborhood Plan Areas; other areas and overlays have separate limits27. Qualifying lots served by central water and sewer can have no minimum individual lot area, but development without both follows state septic lot-size rules28. Certain wetland density transfers require at least 5,000 square feet of non-wetland lot area for single-family lots, except within an approved planned unit development29. Dividing land into 20 or more parcels requires major-development review by the Technical Review Committee, Planning Commission and Board of County Commissioners30. Code-compliant manufactured homes are allowed in residential land-use districts31.

How do septic permits work in Walton County?

Walton County is one of the Florida counties where the Florida Department of Environmental Protection manages septic permitting directly, after DEP took over from the Florida Department of Health in Walton County on January 2, 2025711. To apply, complete DEP's application, site plan and online permit request after the required evaluation of soil and topography3233. Statewide, a septic permit is required to install, replace, repair, modify or abandon an onsite sewage treatment and disposal system, and proof of an OSTDS application can accompany a single-family building-permit application34. DEP's portal provides construction inspection and re-inspection requests for a permitted system, but that does not establish routine inspection of every existing septic system35. Only about 19.1% of Walton County soils carry no severe limitation for a conventional drain field, so schedule the site evaluation before committing to a house location36. A development near an operating sewer system must connect when the system has adequate capacity; septic is the alternative where sewer is inaccessible and applicable approval is obtained37.

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

Unincorporated Walton County generally prohibits permanent RV residence outside licensed RV parks and specified rural-district exceptions38. In Large Scale Agriculture, General Agriculture, Estate Residential, Rural Low Density and Rural Residential, legal lots of 0.5–5 acres outside platted or unplatted subdivisions can qualify for one RV under a Temporary RV Living Permit: up to 90 days, at most twice per calendar year39. Rural Low Density parcels of at least 5 acres allow one temporary RV with or without a primary home, subject to lawful waste disposal, setbacks, no rental and no permanent affixation4041. During primary-home construction, the owner can obtain a one-year permit for one RV on the same parcel where residential primary uses are allowed, with an active building permit; RV use must end within 14 days after the first certificate of occupancy42.

Walton County allows tiny-home ADUs in districts permitting residential development, with design ancillary and compatible with the primary home and neighborhood4344. The code limits ADUs to one per lot, 800 square feet and 75% of the main home's livable area; RVs and short-term vacation rentals are prohibited13. We could not confirm a primary tiny-home minimum size; ask Walton County Planning how the home is classified23.

What are the steps to build a home in Walton County?

  1. Identify the parcel's zoning district, then confirm the use, lot dimensions, setbacks, impervious coverage and height limit with Walton County Planning and Development Services4546474823.
  2. If the property is in a special flood hazard area, obtain the development order before development and the building permit before construction, then satisfy the zone-specific elevation or floodway rules4950.
  3. Determine whether adequate central water and sewer are available; nearby development must connect when those operating systems have capacity37.
  4. If septic is needed, apply early to Florida DEP for the site evaluation and OSTDS permit733.
  5. For a driveway connecting to a county facility, obtain the county driveway permit; the residential application comes with the new-construction building-permit packet51.
  6. Submit the building-permit application and applicable fees to the Walton County Building Division2022.
  7. If acting as your own contractor, confirm which owner-builder pathway applies and personally supervise the work21.

What should you check before buying land in Walton County?

In Walton County flood-hazard areas, temporary RVs and park trailers must stay fewer than 180 consecutive days or remain licensed and highway-ready, with quick-disconnect utilities and no permanent additions, stairs, decks or porches; permanent installation is prohibited52. Regulatory floodways, Zone V and Coastal A Zones prohibit RVs outside existing RV parks, except temporary parking on previously developed parcels when the vehicle will be removed upon a flooding threat52. Ask Walton County Planning to resolve the flood-zone and zoning conditions before relying on an RV pathway2316. Nearby operating water and sewer systems with adequate capacity require connection; a Florida well permit is required before well construction, repair or abandonment, subject to applicable exceptions3753. County-facility driveway connections, replacements and repairs require a driveway permit51. Walton County’s effective property-tax rate is about 0.5%, with a median annual bill near $1,7095455.

Watch-outs

  • Walton County's septic authority changed recently: the Florida Department of Environmental Protection took over septic permitting from the Florida Department of Health in Walton County on January 2, 2025, so don't rely on older references to the county health department's septic program11.
  • Walton County’s temporary RV pathways require lawful gray- and black-water disposal, and construction-use RVs in flood zones must remain operational and ready for immediate highway use3942.
  • Walton County’s ADU FAQ says less than 800 square feet, while the code states a maximum of 800 square feet; ask Planning before designing at that boundary561323.
