Building / Expanding a Home

There are several steps in the permitting process for building a new home or expanding your existing home. See categories below to learn more about the permits and approvals required for each type of project. If you don't see what you are looking for, additional home projects are listed in the "Inside the Home" and "Outside the Home" pages. 

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). Zoning and/or building permit applications for logged-in residential projects will only be accepted if minimum submittal requirements are met.

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).

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

Partnering for safer building

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.
