Clark County, NV Permit Requirements: Renovation Permits (2026)

Clark County requires building permits for renovation work that goes beyond cosmetic changes. The county adopts the International Building Code (IBC) and International Residential Code (IRC) with local amendments under Title 22. Exempt work includes: painting, wallpapering, tiling, flooring, cabinet replacement, and countertop installation that does not modify walls, plumbing, mechanical, or electrical systems. Work requiring permits includes: structural modifications (removing walls, enlarging openings, adding rooms), all electrical work (new circuits, panel upgrades, outlet additions), all plumbing work (fixture relocation, water heater replacement, repipe), HVAC replacement or installation, re-roofing, window replacement that changes rough opening size, and any work adding habitable square footage. Clark County Building permits can be applied for online or at the county building department. Simple residential permits may be issued over the counter for straightforward projects. More complex renovations require plan review, typically taking 2–4 weeks. In Clark County's extreme heat, renovation permits for insulation upgrades, window replacements, and HVAC systems are particularly common as homeowners seek to improve energy efficiency. The county enforces Nevada's energy code requirements for renovations affecting the building envelope.
