When are building, plumbing, and mechanical permits required?

There are very few areas of new construction, repair or alteration that do not require permits. Each of the International Codes specifies that all work requires a permit and then provides exceptions to that rule. The safest course of action is to call the Building Department to determine if work that you propose to do requires a permit. A Permit Coordinator can be reached at 970-920-5090. Please see our Build or Remodel page to learn about requirements and permits for building projects.
