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 deck for help Navigating Denver's Residential Permitting Process (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.

Partnering for safer building


CO Department of Public Health and Environment Logo    Denver Water logo    US Environmental Protection Agency 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. 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. 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.

Thinking of a do-it-yourself (DIY) project?

Are you getting ready to complete a home project and trying to figure out whether to hire a licensed contractor or complete the work as a do-it-yourself project?  Here are some things to consider:

Online Services

Search a list of companies that currently have obtained a contractor's license from the City and County of Denver.  Be sure to check the expiration date and status to make sure the contractor's license is still active.

Submit residential projects by email

Log in your next single-family or duplex project by email. Find instructions here.

e-Plan for Site Development and/or SUDP reviews only

Create an account using the e-plan account application form. Then use e-Plan to submit site development or wastewater plans electronically.

Electronic plan review for fire permits

Apply by email for fire permits that need to be logged in for plan review (e.g., fire suppression, low voltage & fire alarm, CO2 system install, etc.). Download instructions here (PDF).
