While the permit program in Franklin County has been in place for some time, it’s worth noting several critical updates and clarifications you should keep in mind if you’re planning a custom home build: • The county’s building department highlights that “ALL PROJECTS in a special flood hazard area require a permit.” • The county uses an online portal (CitizenServe) for permit submittals, making it easier to apply, track, pay, and schedule inspections. • There are specific wind-load, flood-elevation, and site set-back requirements unique to coastal and vulnerable zones (e.g., the 130 mph or 140 mph wind speed depending on island/coastal location). • Zoning rules such as minimum lot size, building setbacks and impervious coverage remain significant in Franklin County. In short: building a custom home here requires careful preparation. Getting the permit right means less risk of delays and additional costs. ⸻ Step-by-Step Guide to Obtaining the Permit for a Custom Home Here’s a practical pathway for how you’d navigate the process in Franklin County if you are planning a new single-family custom home. 1. Preliminary: Verify Zoning, Lot & Site Conditions • Check the zoning of the lot (e.g., R-1, R-2, etc) via the county’s zoning classifications. • Ensure your lot meets the minimum lot size, width, depth or is an existing lot of record. Example: R-1 minimum is one acre with at least 100 feet width and depth (or existing lot of record) in some districts. • Check required setbacks: e.g., minimum 25 ft from road, 10 ft from side/rear property line, 50 ft from wetlands/mean high water line in some zones. • Verify flood zone, base flood elevation (BFE), whether you are in a “V” zone or coastal hazard area, and what the required elevation/engineered certification will be. • Confirm availability of utilities (water, sewer or septic, well) and whether there are any site‐specific constraints (wetlands, shoreline, critical habitat zones). Tip: If your lot fronts the Gulf or is near mean high water, plan early for the extra requirements (shoreline‐variance, higher setbacks, flood elevation, engineered certification). 2. Prepare Documentation & Plans You will need to assemble the following, among other items: • Two (or more) complete sets of building plans prepared by or certified by a Florida architect or engineer. For some shoreline/coastal zones, wind-load and wave action certifications are required. • A survey of the property by a registered surveyor, showing legal description, parcel ID number, flood information, site topography if required. • A site plan indicating the location of the house, septic system (or sewer), driveway, cleared areas, well or water service. • Proof of septic or sewer (or letter of service) and water well or water district supply. • A Florida Energy Code form (for residential new construction) completed by the owner or installer or engineer/architect. • Notice of Commencement (once construction begins) and other forms (e.g., termite treatment affidavit) as required. 3. Submit Permit Application • You can apply online via the CitizenServe portal (fastest) or in-person/by mail. • If submitting paper: use the county’s “New Residential Building Permit Application” packet. • Make sure the application is complete — incomplete applications get returned and delay processing. • For site-prep, or clearing of vegetation before construction, there may be a separate zoning permit. 4. Plan Review & Approval • Once submitted, the building department reviews the plans, building code compliance, flood elevation, wind load, setbacks, etc. See “Project Guidance” for building projects. • The zoning department may also review the application (especially if in special zones like critical shoreline). • You may receive a request for corrections or additional documentation — this will delay issuance until all corrections are approved. • Once approved, you will receive the permit and you can begin construction. 5. Construction & Inspections • After permit issuance, you must begin work within the timeframe allowed (often within 6 months of permit issuance) and maintain continuous activity. • During construction you will need to schedule required inspections (footings, foundation, framing, plumbing, electrical, final, etc.) — using the online portal helps schedule easily. • If building in a flood hazard area, ensure the finished structure meets the required elevation / engineered drawings. The building department will forbid occupancy until compliance. 6. Final Approval & Certificate of Occupancy • Once construction is complete, the final inspection is scheduled. The “Final Documents” form must be completed (available on county website). • If you complied with all requirements, you will receive a Certificate of Occupancy (or final approval) which legally allows you to occupy the home. • If there are any outstanding issues (e.g., elevation certificate not submitted, sewer/septic not verified), the county may withhold occupancy authorization. ⸻ 5 Key “Watch-Outs” / Tips for a Smooth Permit Process 1. Don’t assume your lot is build-ready. Especially near the coast or in flood zones: knowing your elevation, setbacks, shoreline rules, and whether you need a variance can save major headaches. 2. Wind load and engineering requirements matter. In areas like St. George Island or other exposed locations, you may need certificates for 140 mph wind-load or wave action. 3. Choose your contractor or owner-builder wisely. Homeowners can act as a contractor, but must assume all responsibility. The county’s checklist shows the forms (owner builder affidavit) required. 4. Use the online portal. Submitting online via CitizenServe accelerates the process, allows you to track reviews, pay fees, schedule inspections — faster than paper/mail. 5. Keep records and communicate. After you get the permit, make sure to coordinate pre-construction site-prep (if applicable), inspections, and final sign-off. Delays often come from missing documentation or inspection scheduling hiccups. ⸻ Conclusion If you’re planning a custom home in Franklin County, Florida, the permitting process — while detailed — is quite manageable if you follow the steps and prepare ahead of time. Begin with verifying zoning, flood and site conditions; prepare your plans and supporting documents; submit your application (ideally online); navigate the review; move into construction and inspections; and finally obtain your occupancy approval. By staying organized and proactive, you’ll reduce surprises, avoid costly delays, and be well on the way to building your dream home in this unique and beautiful corner of Florida.
