Columbia County - Lake City, the Gateway to Florida at the I-75/I-10 crossroads - issues building permits through the Building & Zoning Department at 135 NE Hernando Avenue in Lake City. The department runs its own BNZ Portal with token-based secure login for online applications, a public permit search, a live inspection calendar with published AM and PM windows, and a parcel-lookup tool that tells you which authority issues your permit before you apply.
Applies countywide in practice: the City of Lake City has no separate building department, so Columbia County's Building & Zoning Department is the permit authority for city parcels too. Use the county's parcel-search tool to confirm the issuing authority for any address.
What requires a building permit in Columbia 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 - notably F.S. 553.79(1)(g), which can exempt qualifying work valued under $7,500 when it involves no electrical, plumbing, mechanical, gas, or structural work, the home is not in a Special Flood Hazard Area, and the owner submits a written exemption request to the Building Official. Ask the permit counter whether your scope qualifies before assuming a permit is needed.

Columbia County permit types
A building permit is one record among many. the Columbia County Building & Zoning Department 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 Columbia 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 Columbia 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.

Frequently asked questions
How much is a building permit in Columbia County?
Fees follow the department schedule by permit type and project valuation, with trade permits charged separately and re-inspection fees on failed visits. Call Building & Zoning at (386) 758-1008 or email bldginfo@columbiacountyfla.com for current amounts before budgeting.
How long does it take to get a building permit in Columbia County?
Review time depends on project complexity and how complete the submission is - simple trade permits can issue in days, while new construction takes longer as building, zoning, and site reviews route in sequence. The single biggest factor you control is submitting a complete, correctly-documented package the first time; corrections restart the review clock. Electing a private provider under F.S. 553.791 can compress plan-review time on qualifying projects.
How do I look up a permit in Columbia County?
Use the county's public permit search and inspection calendar linked from the Building Department page - permits, inspection schedules, and results are all visible online - or call (386) 758-1008 with the parcel or permit number.
Does Columbia County handle Lake City building permits?
Yes - Lake City has no separate municipal building department, so Columbia County Building & Zoning is the permit authority for parcels inside the city as well as the unincorporated county. The parcel-search tool on the department page confirms the issuing authority for any address.
Can homeowners pull their own permits in Columbia 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 yourself, and not offer the property for sale or lease within one year of completion - and you take on the code-compliance and liability responsibilities a licensed contractor would normally carry.
How long is a Columbia 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 another 180 days. Extensions are requested through the building department before the permit lapses - reapplying after expiration means new fees and current-code review.
Do I need a permit to install solar panels in Columbia County?
Yes. Photovoltaic installations in Columbia 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 Columbia County?
Yes. A roof covering replacement requires a permit in every Florida jurisdiction, including Columbia 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 Columbia County?
Residential work is generally a single-discipline review filed as a master permit with trades filed against it. Commercial work in Columbia 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 Columbia 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 Columbia County?
The application is rejected rather than corrected. the Columbia County Building & Zoning 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 Columbia permit types online?
Most record types are filed through the BNZ Portal, 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.
