Tips
- Henderson uses the 2024 Uniform Mechanical Code (UMC), not the IMC — common to all Southern Nevada jurisdictions.
- Gas piping for mechanical appliances is permitted under the plumbing/gas permit (Table C), not separately.
- For new construction, MPE is bundled in the Table A building permit. Table C fees apply only to standalone work.
- Evaporative coolers ('swamp coolers') are common in Henderson's hot-dry climate — installation requires a mechanical permit at the $319 'repair/alter/add' rate.
