Flood

Approval Timeline
Minor residential permits with complete plans may be reviewed in several business days. Residential additions, decks, garages, and remodels often take 1–3 weeks depending on zoning and plan completeness.

Zoning permits, stormwater documentation, or Board of Architectural Review approvals may be required for certain sites.
Zoning Information
Lexington-Fayette County uses a unified zoning ordinance administered by LFUCG Planning. Zoning review checks allowed use, setbacks, height, parking, landscape requirements, lot coverage, signs, conditional uses, and overlays. Downtown, agricultural, neighborhood business, historic, and planned development areas may have additional design or land-use requirements before a building permit is approved.

Commercial permits are typically valuation-based and may range from several hundred dollars to several thousand dollars, plus separate fees for electrical, mechanical, plumbing, fire protection, sign, or certificate-of-occupancy work.
Engineering Requirements
Engineer or architect seals are commonly required for commercial projects, assembly occupancies, structural alterations, changes in use, non-prescriptive designs, retaining walls over code thresholds, special inspections, and foundations or framing systems that cannot be verified under prescriptive code. For homes, engineered trusses, beams, tall walls, complex decks, basement wall modifications, and significant load-bearing changes often require sealed calculations or manufacturer design documents.
