No. The Town's own Inspections page states plainly that Mt. Crested Butte does not issue electrical permits or perform electrical inspections, and does not perform plumbing inspections — both are handled entirely by the State of Colorado (Colorado Electrical Board and Colorado State Plumbing Board), not the Town Building Division.

Only if the gross floor area is 4,800 sq ft or more (Town Code Sec. 6-59). All two-family dwellings and townhomes require sprinklers regardless of size — a stricter rule than neighboring Crested Butte, which exempts single-family homes from sprinklers entirely.
