Cheyenne's Building Safety: The Rules That Matter

Every city handles building safety a little differently. In Cheyenne, Wyoming, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Plumbing Permits

Cheyenne adopts the 2024 International Plumbing Code by reference under City Code 15.12.010, requiring permits, plan review, and inspections for all plumbing work performed within city limits.

Key details: Code adopted: 2024 International Plumbing Code. Base permit fee: $23.50 for work up to $500. Plan review fee: 65% of the permit fee. Max penalty: $750 fine or 6 months jail. Enforced by: Building Safety Department.

Working without a required plumbing permit or violating the adopted plumbing code is a misdemeanor: up to $750 in fines, six months in jail, or both, per day.

Building Permits

Cheyenne requires a building permit under its adopted 2024 International Building Code for nearly all construction, with narrow exemptions for small accessory structures and low fences.

Key details: Code adopted: 2024 International Building Code. Permit exempt: Accessory structures under 200 sq ft. Permit exempt: Fences not over 6 feet. Permit validity: 1 year, one 180-day renewal. Max penalty: $750 fine, 6 months jail.

Building without a required permit is a misdemeanor under City Code 2.36.020, punishable under the Chapter 1.24 general penalty: up to a $750 fine, six months in jail, or both, with each day a separate offense.

Electrical Permits

Cheyenne enforces the 2023 National Electrical Code and requires a permit from the building safety department before any electrical work begins, with a penalty fee for starting early.

Key details: Electrical code: NEC 2023 Edition adopted. Enforcing agency: Building Safety Department. Early-start penalty: Investigation fee = permit fee. Permit fee basis: Project valuation, § 15.08.030.

Starting electrical work before a permit issues draws an investigation fee equal to the full permit fee; unpermitted work can also be red-tagged and held up pending inspection.

The Bottom Line

Cheyenne's building safety rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Cheyenne is broadly strict or permissive.
