Cheyenne WY bathroom remodel permit rules
Cheyenne's Building Services processes permits at cheyennecity.org. Permits required for system modification — relocated plumbing, new circuits, or structural changes. Cosmetic work at existing rough-ins requires no permit. Call (307) 637-6265. Wyoming does not have a statewide contractor license — verify Cheyenne city contractor registration before work begins. Licensed plumbers and electricians for permitted trade work. Wyoming has no Section 1101.4 equivalent.
Cheyenne is Wyoming's capital at 6,062 feet elevation — the windiest major US city (12.4 mph average, 50+ mph gusts) and served by Black Hills Energy for BOTH electric and gas (single utility). Altitude derates equipment capacity roughly 15% vs. sea-level specs.
Black Hills Energy serves Cheyenne for both electricity and natural gas (1-888-890-5554 / blackhillsenergy.com) — a genuine single utility. For any bathroom project touching both systems, one call covers all utility coordination. Most Cheyenne single-family homes have full or partial basements, giving reasonable access to drain and supply lines from below — a real advantage over slab-on-grade markets where every drain relocation requires concrete cutting.
