Summary

Lake County requires a building permit before you construct, enlarge, alter, repair, move, demolish or change the occupancy of any building or structure in the unincorporated county, per Code § 6-3(a). The Office of Building Services, under the Building Official, reviews applications and issues permits, and a defined list of minor work such as small toolsheds and short decks is exempt.

These county ordinances apply to unincorporated areas of Lake County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Sec. 6-3. - Permits. (a)Any owner or owner's authorized agent who intends to construct, enlarge, alter, repair, move, demolish or change the occupancy of a building or structure, or to erect, install, enlarge, alter, repair, remove, convert or replace any impact-resistant coverings, electrical, gas, mechanical, or plumbing work, or perform any other trade as provided within the scope of this chapter, shall first make application to and obtain a building permit from the Building Official.(b)It shall be the duty of the holder of the building permit or their authorized agent to notify the Building Official when work is ready for inspection and to provide access to and means for inspections of such work.(c)Neither Lake County, nor its Board of County Commissioners and employees, including the Building Official, shall be criminally or civilly liable for damages to persons, property and/or any defect or hazardous or illegal condition or inadequacy in such building, structure, system, or plan, nor for any failure of any component of such, which may occur subsequent to such inspection or permitting. (Ord. No. 2023-44, § 2, 7-11-23)

Full Breakdown

Section 6-3(a) of the Lake County Code makes clear that anyone who intends to construct, enlarge, alter, repair, move, demolish or change the occupancy of a building or structure, or to install electrical, gas, mechanical or plumbing work, must first apply for and obtain a permit from the Building Official before starting. The permit holder must then notify the Building Official when work is ready for inspection and keep the site accessible, per § 6-3(b). Lake County enforces this chapter through the Office of Building Services and, where violations occur, through the code enforcement process in Chapter 8, acting under authority granted by Chapters 489, 162, 455, 775 and 286, Florida Statutes (§ 6-2).

Not every project needs a permit. 2), Lake County exempts a defined list of minor residential work: one-story detached accessory structures such as tool sheds, pergolas, gazebos or playhouses up to 120 square feet built by the owner; retaining walls two feet or less in height; slabs-on-grade of 400 square feet or less with no future structure planned; water tanks up to 5,000 gallons; owner-built freestanding decks up to 30 inches high and 120 square feet; accessibility ramps; flagpoles 25 feet or less; sidewalks and driveways not more than 30 inches above grade; and wood, vinyl or chain-link fences six feet or less (masonry fences four feet or less). 5). 4).

Violations & Fines

Working without a permit is enforced under § 6-22 (FBC § 109.4): the Building Official assesses a fee from the adopted schedule for any work commenced before permit issuance, and an unreasonable delay in applying doubles that fee. The Building Official and code enforcement officers may also issue a stop-work order on any unpermitted work under § 6-6(e), and the case can proceed through the Chapter 8 code enforcement process, which can add its own civil penalties.

Frequently Asked Questions

Do I need a permit to build a shed in unincorporated Lake County?
No, if it is a one-story detached accessory structure such as a tool shed, pergola or playhouse of 120 square feet or less, built by the property owner for personal use, on a single-family lot. Larger sheds, sheds built by a contractor, or those exceeding 120 square feet still need a building permit under § 6-22(e), FBC § 105.2, item 1.
How long is a Lake County building permit valid?
A permit becomes invalid if the authorized work doesn't start within 180 days of issuance, per § 6-22 (FBC § 105.5). The Building Official can grant written extensions of up to 90 days at a time if you show justifiable cause, but an abandoned permit requires either finishing the work to code or removing the partially completed work.
What happens if I build without a permit first?
The Building Official charges a fee under the adopted fee schedule for any work started before the permit is issued, and that fee doubles if you unreasonably delay applying beyond three business days after emergency work, under § 6-22 (FBC § 109.4). Officers may also issue a stop-work order and pursue code enforcement action under Chapter 8.
