Clark County commissioners on Thursday voted to adopt the 2024 editions of multiple building and trade codes, setting an effective date of Jan. 11, 2026, and giving permit applicants a 180‑day transition window to choose the older 2018 codes for projects submitted before the deadline. “For each of these new codes … the Southern Nevada building officials did form a committee for each code,” James Garen, director of the Clark County Building Department, told the board. The package included the 2024 International Building Code, 2024 International Existing Building Code, 2024 International Swimming Pool and Spa Code, the 2023 National Electrical Code (NFPA 70), the 2024 Uniform Plumbing Code, the 2024 Uniform Mechanical Code and the 2024 International Energy Conservation Code with Southern Nevada amendments. Why it matters: The unified adoption aligns county rules with the state and other Southern Nevada jurisdictions, and county officials said the six‑year adoption cadence reduces regulatory burden for the building industry. Garen said code committees required proposed local amendments to be narrowly tailored to regional geology, climate, occupancy types and to correct errata. What the board approved: Commissioners moved and separately approved each ordinance adopting the updated codes (agenda items 29–36). The clerk recorded motions and votes for each item; each motion carried. The county also granted a limited exception for residential standard‑plan subdivisions: if a subdivision had pulled at least one permit under the 2018 residential code and had fewer than 100 houses remaining, developers may finish those remaining lots under the 2018 code (they still must meet the county’s residential sprinkler ordinance). Public comment: Jordan Krambuhel of the Plumbing, Heating, Cooling Contractors of Nevada thanked the county and the building department for coordinating and said statewide adoption of the updated plumbing and mechanical codes improves consistency for training, installation and enforcement. Implementation timeline and coordination: Garen said Clark County will coordinate with the Clark County Fire Department on a matching effective date for their fire code update and that staff will publish transition guidance for applicants. The commission approved the ordinances during a consolidated public‑hearing process; no changes to the adopted effective date were made at the meeting.
