Approvals From Other Agencies Are Required

Fire Department Reviews and Approvals:

The applicant for Building Permit must take two sets of plans for the project to the Fire Department having jurisdiction. The Fire Department concerned then reviews the plans and issues Larimer County Building Department a letter of project approval when the plans have been reviewed and approved by such fire department. Until the Fire Department having jurisdiction issues an "plans approval letter", no building permit will be issued for the project concerned.

Health Department Reviews and Approvals: (Drinking and Dining establishments, Pet Shops.)

The applicant must take a set of all plans by the Larimer County Health Department for review and approval. The health department must sign off/approve plans in the computer system prior to issuance of a building permit. Obtain a copy of the Larimer County Health Department Plan Review Requirements pamphlet for further direction. Kitchen hoods plans must be reviewed and approved by the health department and the hoods inspected on-site by them as well.

State of Colorado Electrical Board:

Larimer County Building Department does not review electrical plans. A separate permit is required from the State of Colorado Electrical Board. The State of Colorado Electrical inspectors do all electrical inspections. (2011 NEC - 2014 NEC as of July 1, 2014)

This handout is not intended to be all-inclusive, it is merely to give a good basic outline as to plan submittal requirements.
