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. Green Cove Springs, Orange Park, Keystone Heights, and Penney Farms run their own building programs — Green Cove Springs, for example, has its own Building Division and application portal.
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)

Clay County permit types
A building permit is one record among many. the Clay County Building Division issues work under separate record types, and filing under the wrong one is a rejection, not a correction — the application is closed and refiled, and the review clock restarts.

Solar permits in Clay County
Solar is permitted as its own record type in most Florida jurisdictions rather than rolled into a general building permit, and residential and commercial photovoltaic are usually separate records with different document sets. Solar thermal — passive water and pool heating — is a third, distinct record.
A photovoltaic submittal is reviewed on two tracks at once: structural (roof load path, attachment spacing, uplift) and electrical (conductor sizing, rapid shutdown, point of interconnection). A single-line diagram and a signed and sealed structural attachment detail are the two attachments most often missing on a first submittal.
Under Fla. Stat. §163.04, a homeowners' association cannot prohibit a solar collector on a dwelling — HOA architectural approval is not a prerequisite to permit issuance, though it may still be a contractual matter between owner and association.
Utility interconnection runs parallel to the building permit, not inside it. Permission to Operate is issued by the utility after the final electrical inspection clears.
Roofing permits in Clay County
A roof covering replacement requires a permit in every Florida jurisdiction. Repairs below the local threshold may not, but the threshold is scope-specific and confirming it with the building department before tear-off is cheaper than an after-the-fact permit.
Every roof product must carry a current Florida Product Approval or Miami-Dade Notice of Acceptance rated for the wind speed at the project address. A product approval number that has lapsed or is rated below the site wind speed is the single most common reroof rejection.
Reroof inspections are sequenced: dry-in after the underlayment, nail-off on the sheathing fastening, and final. Covering the deck before the dry-in inspection means tearing it back open.
Hurricane mitigation retrofit requirements can attach when an existing roof is replaced, including secondary water barrier and roof-to-wall connection work. These add scope and documents, and they are triggered by the replacement itself.
Under Fla. Stat. §553.7922, jurisdictions run expedited procedures for permits that need no technical review — reroofs, roof repairs, and similar — during a declared state of emergency.

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 the parcel is unincorporated Clay County rather than Green Cove Springs, Orange Park, Keystone Heights, or Penney Farms.
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. It's one of the clearest local HB 803 resources in Florida.
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?
Under the Florida Building Code, 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 prohibit a solar collector, so HOA approval is not a prerequisite to permit issuance. Utility interconnection and Permission to Operate run in parallel with the permit, not inside it.
Does a roof replacement require a permit in Clay County?
Yes. A roof covering replacement requires a permit in every Florida jurisdiction, 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 are sequenced — dry-in, nail-off, then final. Some minor repairs fall below the permit threshold, but the threshold is scope-specific.
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. Some records still require in-person submittal, and owner-builder filings are frequently restricted to counter submittal regardless of record type.
