Inside the Home

Depending upon the complexity of your project, the permit requirements and inspection process may vary from the information presented below.

For detailed information on zoning and building permits for projects on single-family homes and duplexes, including minimum submittal requirements, download the Residential Permitting Guide (PDF). 

Also, review our slide decks for help Navigating Denver's Residential Permitting Process (PDF) and Landmark Preservation and Residential Plan Review (PDF), and avoid delays by checking for these common mistakes in residential submittals (PDF). 

If your project involves a home or in-home daycare built before 1978 and would disturb painted surfaces, download the EPA's Renovate Right brochure to learn about the Lead Renovation, Repair and Painting (RPP) Rule and requirements to prevent lead contamination. 

If you have any questions, please contact us.

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.

Denver Water logo

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.
