Residential Mechanical and Plumbing

Permits and inspections for residential replacements and installs of mechanical and plumbing appliances (i.e. water heater, furnace, air conditioner, etc.) are required to be approved and issued before work can be started. Applications can now be submitted through our online customer portal,

Guidelines for Submittal

Please review the table below for the permits available online and the license that is required to apply for the permit. The type of license that has been issued to your company will restrict the type of permit that you can apply for online, please review your license and contact the office if you have questions. Once you are ready to apply for your permit click on the green "Apply for Permit Now" below. Applications can also be made in person at Arvada City Hall 8101 Ralston Rd Arvada, CO 80002, Monday through Friday from 8:00 a.m. to 5:00 p.m.

At this time the online application is only available for contractors that have an active license with the City of Arvada, homeowners that wish to install these appliances will need to submit their application to the Building Inspection Division in City Hall.

 IMPORTANT** Upon inspection of new/replacement mechanical or plumbing equipment, if the inspector notes additional electrical work beyond the allowed disconnect/reconnect has been performed and this work was not included/stated in the permit, the inspection will be failed and a double fee will be assessed for electrical work performed without a permit. Please indicate all electrical work on your permit to avoid unnecessary delays and inconveniences to the homeowner.  If the scope of the work changes mid-project, please call our office to adjust the permit scope before calling for inspections.
