Building permits, zoning and land rules in Bay County, Florida

Unincorporated Bay County requires a building permit before construction, remodeling, renovation, additions, moving or demolition of a building or structure; inside an incorporated city, the appropriate city government handles building permits¹. The Florida Building Code applies statewide and is administered by the applicable local building authority⁸. Permitted work must remain exposed and accessible until the Building Official approves the required inspections⁹. A Bay County owner-builder must register for the county portal and sign the affidavit in person before a county notary before building-permit issuance⁴. Owner-builder status requires direct onsite supervision and a residence for the owner’s use, not offered for sale or lease; building permits and inspections still apply¹⁰. Building-permit cost varies with project size, use and construction type; the county estimates roughly $1,600 for a typical 2,500-square-foot site-built single-family home, including state surcharges and plan review but excluding possible county impact fees⁴. Bay County publishes a separate planning application fee schedule; planning fees are not refunded when a request is withdrawn, denied or granted¹¹. Inside Panama City Beach, the city issues building permits; septic permits remain with Florida DEP^3,12.

The Bay County Building Safety Division is the first stop for building-permit questions in unincorporated Bay County¹. Building-permit documents are submitted through the county online portal; developments other than individual single-family homes follow the county's development-order process¹³. Planning, zoning and floodplain questions go to the Planning & Zoning Division, which reviews development in unincorporated Bay County against the Land Development Regulations². Both offices are at 840 W 11th Street in Panama City: call Building Safety at 850-248-8350 for building permits or Planning & Zoning at 850-248-8250 for zoning approval and floodplain review^1,2. City building and zoning authority does not include septic permitting: Florida DEP handles septic permits throughout Bay County³. After the final inspection passes and required closeout documents are filed, the certificate of occupancy becomes available in the permit portal⁴.

Bay County zoning governs unincorporated land, with an Official Zoning Map and residential, commercial, conservation, industrial and agricultural district regulations^2,14. The county's zoning rules apply to unincorporated land only. Panama City Beach¹⁵, Springfield¹⁶ and Parker¹⁷ set their own zoning inside city limits; septic permits for every Bay County address, city or not, come from Florida DEP³. Bay County minimum lot areas vary by district and special planning area; residential density limits also depend on central water and sewer availability^6,7. In unincorporated R-1 through R-4 zones, standard setbacks are 20 feet in front, 5 feet on the side and 10 feet at the rear; R-5 and R-5A require 25 feet in front and 10 feet on the side and rear⁶. Townhouse developments have an exception to lot-frontage and side-setback requirements, with a 5-foot property-line setback for end units⁶. Impervious-surface limits are 60% in R-1 through R-4 and 75% in R-5 and R-5A; height limits vary by district and urban or suburban location⁶.

Florida DEP handles onsite sewage treatment and disposal system permits throughout Bay County, including addresses inside incorporated cities³. A new system requires a septic construction permit; repairs, modifications and abandonment have their own septic permit requirements¹⁸. Bay County septic applicants need the DEP4015 application, a site plan, a building floor plan and a site evaluation of soil, topography and installation conditions; submit through DEP’s online portal or by mail³. A qualified private site evaluation must be completed before submission and uploaded; applicants may instead request DEP’s evaluation³. A building or plumbing permit generally cannot issue for a building needing septic until the owner or builder receives the septic construction permit; for a single-family residence, proof of a submitted septic application may accompany the building or plumbing application¹⁹. Only about 6.5% of Bay County soils lack severe limits for a conventional drain field, so complete the evaluation before fixing the house location or septic budget²⁰.

In unincorporated Bay County, manufactured homes are allowable uses in R-2 and R-4, but are prohibited in the Beaches Special Treatment Zone regardless of zoning designation⁶. Garage apartments, guesthouses and domestic quarters are listed accessory uses in R-1, with those uses incorporated into the other residential zones; a principal use or structure must exist⁶. Accessory uses generally belong in side or rear yards, with a waterfront-lot exception; except for fences, accessory uses need at least 5 feet from side and rear property lines and must meet the Florida Building Code where applicable⁶. Ask Planning & Zoning to confirm the proposed dwelling use before choosing a design². We could not confirm general long-term RV occupancy, temporary private-land camping, tiny-home occupancy or a minimum dwelling floor area in unincorporated Bay County; ask Planning & Zoning and Building Safety about the parcel and proposed home^1,2. Covered short-term rentals in unincorporated Bay County require a Short-Term Vacation Rental Certificate; high-rise condominium units and apartment complexes are exempt²¹.

1. Ask Planning & Zoning to confirm the parcel's district, allowed use, density, setbacks, impervious-surface limit, height limit, utility availability, special-area status and flood status^2,6,7.
2. If the home will use septic, prepare the septic permit application, site plan, floor plan and site evaluation for Florida DEP³.
3. Submit the building-permit documents through the Bay County online portal and budget for a fee based on the project's size, use and construction type^1,4,13.
4. If acting as your own contractor, appear at Building Safety and sign the Owner-Builder Affidavit before a county notary prior to building-permit issuance⁴.
5. Keep permitted work exposed for required building inspections, then pass the final inspection and file the closeout documents to receive the certificate of occupancy^4,9.

Before buying unincorporated Bay County land, confirm zoning and flood status with Planning & Zoning². Bay County subdivision plans require a Development Order application and general development plan, with compliant plats before final approval and recording; optional conceptual review is free, and specified lot-split or lot-shift exceptions apply²². Development subject to Bay County flood-management regulations requires a floodplain-development permit; nonconforming-structure repairs or remodeling require a cost estimate and appraised value for review⁵. Bay County counts improvements across a 10-year period toward its 50%-of-market-value substantial-improvement threshold⁵. A residential connection to a county-owned or county-maintained right-of-way requires a driveway permit and acceptance before a certificate of occupancy; existing-driveway verification also requires a permit, with the fee waived²³. Florida requires a water-well permit from the appropriate water management district or delegated authority before construction, repair or abandonment; we could not confirm the local issuing office for Bay County, so ask Planning & Zoning where to start^2,24.
