Gulf County's Building Department provides construction plan review, building permits, inspections, and code enforcement countywide from Room 400 of the Gulf County Courthouse Complex at 1000 Cecil G. Costin Sr. Blvd. in Port St. Joe — adjacent to the Robert M. Moore Administration Building. Plan around two scheduling quirks: county offices run a four-day week, Monday through Thursday, 7:00 a.m. to 5:30 p.m. Eastern Time, and Gulf is one of the rare Florida counties split between time zones — the north end around Wewahitchka keeps Central Time while the county offices run on Eastern — so confirm which clock your inspection window is on.
The county has adopted the Florida Building Code 2023, 8th Edition, and — in the biggest recent process change — septic permits moved out of the county entirely as of January 1, 2025: the Florida Department of Environmental Protection now issues them through FDEP's online portal, with the landowner responsible for verifying Gulf County BOCC ordinance and density compliance before submitting to FDEP.
Applies to unincorporated Gulf County, including the Cape San Blas / Indian Pass beach communities and the Wewahitchka side. The City of Port St. Joe runs its own building office at 1002 10th Street (850-229-1093) - confirm the routing for city-limits parcels before filing.

How to get a building permit in Gulf County
Confirm jurisdiction
Verify the parcel is unincorporated Gulf County — not inside the City of Port St. Joe, which runs its own department at 1002 10th St. ((850) 229-1093) with published 5-day residential review.
Handle septic through FDEP
For projects needing septic, verify Gulf County BOCC ordinance and density compliance first, then submit the application online through the FDEP portal — the county no longer issues septic permits as of January 1, 2025.
Prepare the package
Assemble the county application with plans, valuation, contractor licensing, Florida Product Approval documentation, and flood-zone elevation materials where applicable.
Submit in Room 400
File at the Building Department, Room 400 of the Courthouse Complex, Monday–Thursday 7:00 a.m.–5:30 p.m. ET. Record a Notice of Commencement where required.
Plan review & issuance
The department reviews plans for code compliance under FBC 2023 and issues the permit.
Inspect through close-out
Schedule inspections through the department — on the Eastern Time clock — and clear all inspections through final.
Inspections in Gulf County
Inspections are scheduled through the Building Department within its Monday–Thursday, 7:00–5:30 Eastern Time week — there are no Friday inspections, and crews on the Central Time side of the county should book against the office's Eastern clock. Keep the permit and approved plans on site, and have flood and elevation documentation ready on coastal parcels before calling for foundation-stage inspections.

Frequently asked questions
How long does it take to get a building permit in Gulf County?
Build the four-day week into your schedule — with no Friday service, a package submitted Thursday afternoon effectively waits until Monday. Simple permits move quickly once complete; coastal projects add flood and elevation review, and septic-dependent builds now wait on the FDEP portal step, which should be started first. Call (850) 229-8944, ext. 1 for current review times.
How do I look up a permit in Gulf County?
Gulf County does not run a public online permit-search portal; permit lookups go through the Building Department at (850) 229-8944, ext. 1 with the parcel or permit number. The department's page posts current applications and notices, including the 2025 septic permitting change.
Who issues septic permits in Gulf County now?
The Florida Department of Environmental Protection. As of January 1, 2025, the Gulf County Environmental Health Department no longer issues septic permits — applications are submitted online through the FDEP portal, and it is the landowner's responsibility to verify that the application meets all Gulf County BOCC ordinance and density requirements before submitting to FDEP.
What are the Gulf County Building Department's hours?
Monday through Thursday, 7:00 a.m. to 5:30 p.m. Eastern Time, in Room 400 of the Courthouse Complex — the county runs a four-day week, so plan submittals and inspections around no-Friday service. Note that Gulf County spans two time zones; the county offices keep Eastern Time.
Does the City of Port St. Joe review plans faster than the county?
The city publishes its own timelines: residential plans are reviewed within 5 working days with the permit issued on approval, and commercial plans normally take no more than 30 days depending on complexity. Inside city limits, that department — 1002 10th St., (850) 229-1093 — is your jurisdiction, not the county.
What building code does Gulf County enforce?
Gulf County has adopted the Florida Building Code 2023, 8th Edition. On the coast, expect the wind and flood provisions to drive product-approval and elevation documentation — the standard that hardened across the area after Hurricane Michael.
Do I need a permit to install solar panels in Gulf County?
Yes. Photovoltaic installations in Gulf County are permitted under a dedicated solar record type reviewed on both a structural and an electrical track. Solar thermal — passive water and pool heating — is a separate record. Under Fla. Stat. §163.04 a homeowners' association cannot ban solar panels, though it can decide where on the roof they go if that does not reduce their performance; HOA review is separate from the building permit. Utility interconnection and Permission to Operate run in parallel with the permit, not inside it.
Inspections are where schedules slip.
Get a free quote →Does a roof replacement require a permit in Gulf County?
Yes. A roof covering replacement almost always requires a permit in Florida, including Gulf County. Products must carry a current Florida Product Approval or Miami-Dade Notice of Acceptance rated for the wind speed at the project address, and inspections usually run deck nailing, then dry-in, then final. Some minor repairs fall below the permit threshold, and a small single-family job under $7,500 can qualify for the written-request exemption under F.S. 553.79(1)(g), so ask the department first.
What is the difference between a residential and a commercial permit in Gulf County?
Residential work is generally a single-discipline review filed as a master permit with trades filed against it. Commercial work in Gulf County runs concurrent review across building, fire, and zoning, requires signed and sealed plans for every affected discipline, and can carry impact and concurrency fees on top of permit fees. Change of use adds accessibility and life-safety review.
Do trade permits need to be pulled separately in Gulf County?
Yes in most cases. Electrical, plumbing, and mechanical work is permitted separately by the licensed contractor for each trade and filed against the master building permit. Each trade permit carries its own fee and its own inspection sequence.
What happens if I file under the wrong permit type in Gulf County?
The application is rejected rather than corrected. the Gulf County Building Department closes the record, the filing is resubmitted under the correct record type, and the review clock restarts from zero. Confirming the record type before filing is the cheapest step in the entire process.
Can I apply for all Gulf permit types online?
Applications are filed at the counter in Room 400 of the Courthouse Complex or by email, with every document on the application checklist attached; the county does not offer online portal filing. Owner-builder filings are frequently restricted to counter submittal regardless of record type.
