Building Permit Guide for Alachua County, Florida

Alachua County is home to Gainesville, the University of Florida, and roughly 280,000 residents spread across a mix of urban neighborhoods, college-town streets, and rural acreage. If you're planning a construction project here — an addition, a pool, a fence, or even a carport — you need a building permit before work begins. But Alachua County has a jurisdictional split that trips up many homeowners: the City of Gainesville and several other municipalities each run their own building departments separate from the county. Understanding which office to contact is the first step in any permit process.

Who Issues Building Permits in Alachua County?

Alachua County's Growth Management Department issues permits for all properties in unincorporated Alachua County — the areas outside any incorporated municipality. The county office is located at 10 SW 2nd Avenue, Gainesville, FL 32601, and can be reached at (352) 374-5243. Hours are Monday–Thursday, 8:00 a.m.–4:00 p.m., and Friday, 8:00 a.m.–1:00 p.m.

If your property is within an incorporated city, you'll deal with a different office entirely:

• City of Gainesville: The City's Sustainable Development Department issues building permits. Applications go through the PermitGNV portal at gainesvillefl.gov. The City also reviews projects in designated historic districts through the Historic Preservation Board, which adds time to the plan review process.
• City of Alachua, Newberry, High Springs, and other municipalities: Each city operates its own building office. Always confirm your property's jurisdiction with the Alachua County Property Appraiser before submitting any application.

How Do You Apply for a Building Permit in Alachua County?

For unincorporated Alachua County, the Growth Management Department offers an e-Permitting system at epermit.alachuacounty.us for projects that don't require a full plan review. Trade permits — roof replacements, water heater replacements, and HVAC changeouts — are the most common candidates for the online portal. State-licensed contractors registered with Alachua County's Building Department can submit applications, pay fees, and schedule inspections entirely online.

Projects requiring plan review — room additions, pools, new construction, and structural changes — must be submitted with construction drawings that meet Florida Building Code requirements. Plans examiners review the submitted drawings and will issue a comment letter if corrections are needed. Once approved, the permit is issued and the applicant can schedule inspections through the same portal. For City of Gainesville projects, the PermitGNV portal offers similar online functionality. Applications can also be submitted in person, by email, or by mail.

What Projects Require a Permit in Alachua County?

Under the Florida Building Code — which applies in all 67 counties — a permit is required before you construct, enlarge, alter, repair, move, or demolish most structures and systems. In Alachua County, this includes but is not limited to:

• Roof replacements and any re-roofing work
• Swimming pools, spas, and hot tubs
• Room additions and garage conversions
• Electrical work beyond simple fixture swaps, including panel upgrades and new circuits
• Plumbing work involving new lines, repiping, or adding fixtures
• HVAC replacements and new system installations
• Fences above a certain height (typically 6 feet in the right-of-way setback)
• Accessory structures such as sheds, detached garages, and carports above the permit-exempt size threshold
• Decks, pergolas, and patio enclosures attached to the principal structure

Florida's HB 803 (effective July 1, 2026) created exemptions for certain single-family residential repairs under a dollar threshold, but the exemptions are narrowly defined. When in doubt, call the building department before starting work — a quick confirmation call is far less costly than an after-the-fact permit or a stop-work order.

How Much Does a Building Permit Cost in Alachua County?

Alachua County permit fees are calculated based on the declared construction value of your project, with the exact formula set by the county's building permit fee schedule. Like most Florida counties, Alachua also charges plan review fees for projects requiring engineering review, trade sub-permit fees for electrical, plumbing, and mechanical work, and state-mandated surcharges.

One notable provision: properties with a homestead exemption and a total just value below $50,000 receive a 50 percent reduction on building permit fees in unincorporated Alachua County. This can make a meaningful difference for homeowners in lower-assessed neighborhoods making essential repairs. For a statewide overview of how Florida permit fees are structured across project types, see our Florida building permit costs guide.

How Long Does Permit Approval Take in Alachua County?

Simple trade permits — roof replacements, water heaters, HVAC swaps — submitted through the e-Permit portal can often be approved within 1 to 3 business days when the application is complete. Projects requiring plan review take longer. Room additions, pools, and new construction typically involve a 2 to 4 week plan review cycle for the first submission; if the plans examiner issues corrections, add another cycle for each resubmission.

In Gainesville, the City's building division follows a similar timeline. Projects in historic districts add an unpredictable layer — review by the Historic Preservation Board meets on a set schedule and can push approval out by several additional weeks. Plan for extra lead time if your property is in a historic overlay district.

Do You Need a Notice of Commencement in Alachua County?

Yes, for most construction projects above a dollar threshold — generally $2,500, though specific limits vary — Florida law requires a Notice of Commencement (NOC) to be recorded with the Alachua County Clerk of the Circuit Court before work begins. The NOC protects property owners from construction liens filed by subcontractors and material suppliers who weren't paid by the general contractor. Your licensed contractor typically prepares and records the NOC, but as the property owner it's your responsibility to ensure it's in place before the first day of construction. Failing to record the NOC before work starts is one of the most common compliance mistakes on permitted projects in Florida.

Can a Homeowner Pull Their Own Permit in Alachua County?

Yes. Florida's owner-builder exemption allows homeowners to act as their own general contractor on their primary residence without holding a contractor's license. You must personally own and occupy the home, sign the permit application, and accept legal responsibility for code compliance, inspections, and worker's compensation obligations. The exemption cannot be used on a structure you intend to sell or rent within one year of completion, and you may not hire unlicensed subcontractors. For the full rules, see our owner-builder permit guide.

What Happens If You Build Without a Permit in Alachua County?

Unpermitted construction in Alachua County carries the same consequences as anywhere in Florida: stop-work orders, daily fines, and a potential requirement to demolish or expose completed work for inspection at your own expense. Your homeowner's insurance carrier may deny claims tied to unpermitted structures, and the problem will surface on any four-point inspection or title search when you go to sell. Buyers' lenders routinely refuse to close on properties with open or unresolved permit issues. For a full breakdown of the risks, read our guide on what happens if you build without a permit in Florida.

Most counties — Alachua County included — offer an after-the-fact permitting process for unpermitted work, typically at double the normal fee. The sooner you address it, the lower the total cost.
