Denver requires electrical permit for hot tub/spa installation (240V 50-amp typical). Locking safety cover (ASTM F1346) can substitute for barrier per 2021 ISPSC §305.5. Setbacks per zone district.
Denver requires an electrical permit for every hot tub or spa installation due to the 240V 50-amp GFCI-protected circuit typically required. Building permit required if weight exceeds 1,000 lbs on an elevated deck or if structural modifications are needed. Under the 2021 International Swimming Pool and Spa Code §305.5 adopted by Denver, a hot tub or spa with a safety cover complying with ASTM F1346 standard is exempt from the 5-foot barrier requirement that applies to in-ground pools. The cover must be locked when not in use. Setback requirements vary by Denver Zoning Code district — typically 5 feet from side and rear property lines, further from the front. Drainage must go to sanitary sewer (not storm drain) to handle chlorinated water. Denver Water may have additional requirements for drain size. Outdoor hot tubs in bear zones should have lockable covers for wildlife deterrence.
Unpermitted electrical: stop-work, 2x retroactive permit fee. Safety cover missing/broken: $150 to $500 and use prohibited. Drainage to storm sewer: $500 to $999 Denver Public Health.
