Clay County — Green Cove Springs, Orange Park, Middleburg, and the fast-growing First Coast Expressway corridor — issues building permits through the Building Division for unincorporated Clay County. Permitting and Development Services now operate from the new Development Services Building at 435 Walburg Street in Green Cove Springs, and every application files through the Citizens Access Portal (CAP) on Tyler Technologies EPL.
Applies to unincorporated Clay County and to Keystone Heights, where the city’s Public Works Director approves the permit first and it is then submitted to the county. Green Cove Springs and Orange Park run their own building programs, and the Town of Penney Farms issues its building permits at Town Hall.
What requires a building permit in Clay County?
Under the Florida Building Code (§105.1), a permit is required before you construct, enlarge, alter, repair, move, demolish, or change the occupancy of most structures and systems. New for 2026: Florida HB 803 (effective July 1, 2026) created additional building-permit exemptions for certain single-family residential work. Ask the permit counter whether your scope qualifies before assuming a permit is needed. Clay County's own HB 803 guidance page — linked in the resources below — explains how to request the new exemptions.
Permit required
- New homes, additions, and commercial construction
- Structural or load-bearing alterations and demolition
- Roof replacements and window / door replacements
- Electrical service changes and most wiring work
- Mechanical / HVAC installations and changeouts
- Plumbing alterations, repipes, and water heaters
- Sheds, additions, and projects needing Planning & Zoning pre-review
- Pools, spas, and screen enclosures
Usually exempt
- Painting, flooring, cabinets, and cosmetic finishes
- Like-for-like minor repairs that don't alter systems
- Routine maintenance that doesn't extend or reroute systems
- The two new HB 803 single-family exemptions (see the county's guidance)

How to get a building permit in Clay County
Confirm scope & jurisdiction
Verify the work needs a permit — check the county’s HB 803 guidance for the new exemptions — and confirm who permits the parcel: the county for unincorporated land and (after city Public Works approval) Keystone Heights; Green Cove Springs, Orange Park and Penney Farms issue their own.
Prepare your documents
Assemble the application, proof of ownership, plans, flood or septic documentation where applicable, and complete any required Planning & Zoning pre-review for projects like additions and sheds.
Apply through CAP
Register in the Citizens Access Portal (a valid email is required for notifications) and submit the application and plans; contractors register their qualifying-agent documents and insurance with the Building Department first.
Plan review & corrections
Reviews route through the portal with comments posted to your account; the portal reopens for revisions when review completes — upload corrections promptly.
Pay fees & pull the permit
Pay building, trade, and applicable school/mobility/county impact fees, then print the permit.
Record the NOC & inspect through close-out
For jobs over $5,000 (mechanical over $15,000), record the Notice of Commencement with the Clerk — it must include the permit number — and provide the certified copy before the first inspection. Schedule inspections in CAP and pass the final.

Frequently asked questions
How much is a building permit in Clay County?
Fees follow the county schedule by permit type and valuation, but the real budget drivers on new construction are the separately posted school impact, mobility, and county impact fee schedules — all four live on the Building Division's fee page.
What are Clay County's Notice of Commencement rules?
A recorded NOC is required for building permits over $5,000 in job value (mechanical over $15,000), the certified copy must reach the Building Department before the first inspection, and — since September 1, 2023 — the NOC must include the permit number or the county won't accept it.
Does Clay County have HB 803 guidance?
Yes — the county publishes its own explainer on the two new single-family exemptions effective July 1, 2026, including when they apply and how to request them.
Can homeowners pull their own permits in Clay County?
Yes, with limits. Florida's owner-builder exemption (F.S. 489.103(7)) lets you permit work on a home you own and occupy, but you must appear and sign the disclosure, supervise the work, and not offer the property for sale or lease within one year of completion.
How long is a Clay County permit valid?
For a single-family home, Florida law keeps a permit valid for at least 1 year after issue, or until the next Florida Building Code edition takes effect if that is later (since 1 July 2026). For other work, a permit generally expires if work does not start within 180 days of issuance (or stalls for 180 days); each passed inspection typically extends it. Extensions are requested through the department.
Do I need a permit to install solar panels in Clay County?
Yes. Photovoltaic installations in Clay 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 Clay County?
Yes. A roof covering replacement almost always requires a permit in Florida, including Clay 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 Clay County?
Residential work is generally a single-discipline review filed as a master permit with trades filed against it. Commercial work in Clay 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 Clay 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 Clay County?
The application is rejected rather than corrected. the Clay County Building Division 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 Clay permit types online?
Most record types are filed through the Citizens Access Portal (CAP), but availability varies by permit type and by applicant. Florida law requires building departments to accept completed applications electronically, but owner-builders must still appear in person to sign (F.S. 489.103(7)).
