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

Yes.

Yes. Washington County requires a permit for covered construction and installations, and work must not start before the permit is issued¹. Separate permits are identified for electrical work, plumbing, signs, wells, pools, furnaces, boilers, heaters, tanks and air conditioners¹. The county's application uses the Florida Building Code in effect for its permit review¹.

Inspections require the proper building, plumbing, electrical, mechanical and roofing permits, plus the permit number and inspection type when the inspection is requested⁸. An improvement costing $2,500 or more also requires a Notice of Commencement to be provided and posted before the first inspection⁸.

Who issues building permits in Washington County, Florida?

The Washington County Building Department issues building permits, reviews plans, performs electrical and building inspections, maintains contractor licensing and provides a permit-search portal.

The Washington County Building Department issues building permits, reviews plans, performs electrical and building inspections, maintains contractor licensing and provides a permit-search portal⁹.

Washington County's published application collects project, owner, contractor, occupancy, building, valuation and trade-permit information¹.

Does Washington County, Florida have zoning?

The Washington County Planning Department administers the Land Development Code and Comprehensive Plan in unincorporated Washington County and in Caryville, Ebro, Vernon and Wausau; the cited rule does not establish county administration in every municipality or address Chipley.

For development reviewed in unincorporated Washington County, setbacks come from the parcel's Future Land Use Map category, and the site plan must show distances from property lines, the center line of an abutting right-of-way and adjacent buildings or structures¹⁰. Ask Planning for the applicable distances and for parcel-specific answers on minimum dwelling size, minimum lot size and tiny-home occupancy, which we could not confirm². Off-site-built dwellings treated as real property must be allowed where single-family detached homes are allowed, subject to generally applicable permitting, installation, health, utility and development standards¹¹.

How do septic permits work in Washington County, Florida?

Florida DEP handles onsite sewage treatment and disposal system permitting in Washington County, taking over that county function on January 2, 2025.

Florida DEP handles onsite sewage treatment and disposal system permitting in Washington County, taking over that county function on January 2, 2025⁴. A permit is required to construct, repair, modify or abandon a septic system, and the application includes DEP4015, a site plan, a building floor plan and submission through DEP's online portal⁵. The required site evaluation examines soil, topography and other installation conditions⁵.

Only 8.2% of county soils are rated without severe limits for a conventional septic drain field, so make the site evaluation part of the purchase contingency instead of assuming a conventional layout will work¹². For permit-status questions, Northwest Florida field services lists OSP_NWSA@floridadep.gov and 850-595-0656, and its Washington County group is expressly identified¹³.

Can you live in an RV or tiny home in Washington County, Florida?

Permanent residential use of an RV is prohibited in Washington County, and only structures approved by Planning will receive an address.

Permanent residential use of an RV is prohibited in Washington County, and only structures approved by Planning will receive an address³. The county rule does not answer short-term or temporary camping, so ask Planning about the specific parcel and proposed duration before moving an RV onsite³. Planning requests the parcel identification number, property address, owner of record and a brief proposal description when answering development questions².

Washington County's materials do not give a confirmed rule for tiny-home occupancy or a local minimum dwelling size. Ask Planning whether the proposed unit qualifies as a dwelling in the parcel's Future Land Use Map category and what setbacks apply¹⁰. A manufactured home treated as real property is allowed where single-family detached dwellings are allowed, subject to generally applicable setbacks, installation, permitting, health and utility requirements¹¹.

Building a home in Washington County, Florida: what are the steps?

Send Planning the parcel identification number, address, owner of record and proposed development description; obtain land-use approval, confirm the Future Land Use Map setbacks and ask for parcel-specific flood information.

Send Planning the parcel identification number, address, owner of record and proposed development description; obtain land-use approval, confirm the Future Land Use Map setbacks and ask for parcel-specific flood information^2,10.
Obtain a valid E-911 address⁹. For a new home on a county-maintained road, apply to Public Works for a driveway permit; use FDOT instead for a state-maintained highway¹⁴.
Apply to Florida DEP for the septic permit and site evaluation, using the required application, plans and online portal⁵.
Submit the building application with project, ownership, contractor, occupancy, valuation and applicable trade information; do not start work before issuance¹.
Schedule required inspections with the permit number and inspection type, and post a Notice of Commencement before the first inspection when the improvement costs $2,500 or more⁸.

What should you check before buying land in Washington County?

Start with land use, flood exposure, legal access, septic feasibility and water.

Start with land use, flood exposure, legal access, septic feasibility and water. Planning advises buyers to contact the office before purchase for parcel-specific flood information². If land will be split, a subdivision requires an approved plat; a division into parcels of at least 4.5 acres avoids platting only when every parcel meets the stated roadway conditions and the division follows development-plan review¹⁵. Only 8.2% of county soils are rated without severe limits for a conventional septic drain field, so make the site evaluation a purchase contingency¹².

A private water well requires a permit from the appropriate water management district or its delegated authority before construction, repair or abandonment⁷. If public sewer later becomes available, a properly functioning septic system generally must connect within 365 days after written notice, subject to the rule's conditions and possible waiver¹⁶. The effective property-tax rate is about 0.5%, and the median annual property-tax bill is $787¹².

Watch-outs

Do not begin covered construction before Washington County issues the permit¹.
Confirm flood information with Planning before purchase; development in a flood zone may require additional review².
Permanent residential RV use is prohibited; temporary camping, tiny-home occupancy and a local minimum dwelling size remain unconfirmed, so ask Planning for a parcel-specific answer^2,3.
A new residential driveway on a county-maintained road needs a Public Works permit before electrical power is authorized; state-highway access goes through FDOT¹⁴.
The owner-builder route still requires direct onsite supervision and compliance with applicable codes and zoning⁶.

Florida rules that apply here

Owner-builder exemptionConditional
An owner acting as the owner's own contractor for construction, improvement, maintenance, repair, alteration, or addition to a one-family or two-family residence in Florida for the owner's own use and occupancy.
- The owner must provide direct, onsite supervision of all work not performed by licensed contractors.
- The residence must be for the owner's occupancy or use and must not be offered for sale or lease.
- The owner must personally appear and sign the building permit application and satisfy any local permitting-agency requirements demonstrating understanding of the owner's legal obligations.
- The owner may not delegate direct supervision to another person unless that person is registered or certified under Chapter 489 and the work is within that person's license scope.
- The exemption does not exempt a person employed by or under contract with the owner who acts as a contractor; unlicensed workers must work under the owner's direct supervision and be employed by the owner, with applicable FICA withholding and workers' compensation compliance.
- A sale or lease, or offer of sale or lease, of the structure within 1 year after completion creates a statutory presumption that the construction was undertaken for sale or lease.
- The owner-builder exemption does not eliminate the state building-permit requirement for covered construction. Florida law generally makes construction unlawful without first obtaining a permit from the appropriate enforcing agency, subject to specified statutory exceptions.
- The owner-builder exemption does not create a blanket inspection exemption. Permit and code compliance are administered through the applicable local enforcing agency, and the construction must comply with applicable laws, ordinances, building codes, and zoning regulations.
