Homes in unincorporated Gunbarrel get building permits from Boulder County Community Planning & Permitting, not the City of Boulder. Replacing a water heater needs a permit: it isn't on the county's list of exempt work. The fee is based on job value and starts at $38.95 for work up to $800, before plan check and taxes. Owners working on their own property aren't treated as contractors. Xcel supplies gas and electricity.
Gunbarrel is an unincorporated community in Boulder County, so county offices handle permits.
