Tips

  • Cheyenne's winter design temperature is -1°F with 7,381 heating degree days per the Building Safety Department's design criteria — HVAC sizing should account for this severe heating load.
  • Gas fireplaces/logs are specifically called out on the City's combined Plumbing/Mechanical/Electrical permit application form (a Yes/No + count field) — they require a permit.
  • 2026-07-17 rotation audit: re-confirmed live via Municode Ch. 15.16.010 that the 2024 International Mechanical Code is the current adopted edition (Ord. No. 4613, §5, 2-24-25); the valuation-based fee table and 65% Plan Review Fee were also re-confirmed against the live Schedule of Fees PDF. The winter design temp (-1°F) / 7,381 HDD figure could not be re-confirmed this pass — it does not appear on the City's current live Table R301.2(1) design-criteria table (which replaced/updated other figures like wind speed and snow load), so treat it as carried over from the older 2023 handout until a current source is found.
