Repair/replace projects include replacing existing materials or utilities (plumbing, electrical, and mechanical) in commercial and residential properties. Required permits and approvals can vary for projects on the exterior of the property versus the interior of the property.   

In some situations, a "Quick Permit" or no building permit is required. See Quick Permits for more information. Many projects that are ineligible for a quick permit may be permitted at the Commercial/Multifamily Walk-through Counters

Guidance on dealing with asbestos and lead

CO Department of Public Health and Environment Logo

Colorado requires an asbestos inspection before remodeling if there might be asbestos-containing materials, and before any demolition work. This inspection determines whether abatement is required. Unsafe removal of asbestos releases microscopic fibers that can cause severe lung disease and cancer when inhaled.

Learn more about state asbestos rules and permits.

To prevent breaks, low-pressure issues, and health risks, replace water service lines that are older than 50 years or that are made of non-copper materials, particularly lead and galvanized pipe. Contact Denver Water Sales Administration to find out if the water lines on your property need to be replaced.

Learn when and how service lines must be replaced.

US Environmental Protection Agency logo

The EPA requires firms performing renovation, repair, and painting in homes, childcare facilities and preschools built before 1978 to use an EPA-certified renovator trained to follow specific work practices to prevent contamination from lead-based paint.
