*Tips For Completing Mail In Permit Applications

Section 150.2 of the Denver Building Code Amendments states which work activities do not require building permitting for mechanical, electrical, plumbing, and other construction activities. Adminstrative Policy 150.2.2 provides additional exemptions to Section 150.2.2. 

*A permit from Wastewater Management, Zoning Administration, or the Fire Department may be required even if a building permit is not required.
