Demolition of residential and commercial structures that are 120 square feet or greater require a permit review process including review, permits and inspections. Demolition of a structure less than 120 square feet does not require a review, permits or inspections with the City.  

Landmark Preservation reviews all applications for total demolition to determine if the structures have potential for historical signficance.

The Total Demolition Guide (PDF) contains the step-by-step procedures for total demolition of residential and commercial structures, submittal checklist, and required applications.  

If your property is located within a historic district or designated as a landmark structure, additional steps may apply.  Use the DevelopDENVER tool to the right to determine the landmark status.  Contact the Landmark Preservation staff at 720-865-2709 or email to learn more.

Partial Demolition (demolition preparing for construction)

If you are demolishing a portion of your structure such as the removal of walls or sections of the roof in preparation for additions or remodeling projects, that demolition is to be included in the scope of work of construction permits.  The following permit/reviews are required:

  • #1C permit - (commercial projects only)
  • #1R permit - (residential projects only)


Help Me Get Started . . .

Before you start your project, you need to know what regulations apply to your property and what factors may impact your project. You'll need to consider:

Historic Landmark Status

Any project that involves changes to the exterior of landmark structures or properties in historic landmark districts must be reviewed by Landmark Preservation staff before you begin. The appropriate zoning, building, curb cut, or revocable permits needed for the project will be issued only after design review has been completed and the project has been approved. To determine your property’s landmark status, use the DevelopDENVER tool to the right. Then, visit the design review web page for more information.


Zoning establishes standards for things such as the size and location of structures and acceptable uses for your property. Before you begin construction, you need to be sure your project is in compliance with the Denver Zoning Code. Use the DevelopDENVER tool to the right to determine the zoning for your property. In the results, click on your zone district for descriptions and definitions; then, click on your neighborhood context for more information on zoning in your area.

Denver Forestry

If any portion of your project has the potential to affect the trunk, canopy or roots of the street trees around your property, before you begin, you must contact Denver Forestry by email ( or phone (720-913-0651) to evaluate your project.  Any removal, trimming or planting of trees within the public right of way must be permitted through the City Forester’s Office.  Damages to street trees may result in the issuance of administrative citations and/or fines.  Visit the Denver Forestry web page and click on Property Owner Resources for information on hiring a licensed tree service company or requesting a permit.

Building Code

Denver Building Code provides minimum standards for building in order to safeguard public safety, health and welfare. The permitting and inspection process ensures that all home projects meet these standards and that all dwellings are safe and habitable at the time of construction.

Location of Utilities

When designing your project, you need to know where utilities are located. You cannot build over existing utilities. Before you dig, contact the Utility Notification Center of Colorado at 1-800-922-1987 or 811 to mark underground utilities for your project.

Location of Existing Sewer Lines

If you plan to build a new structure over or within 2 feet of the existing sanitary sewer, you will need to replace the sanitary sewer with approved materials. A plumbing contractor can help you locate the sewer lines on your property. Visit Wastewater Sewer Use and Drainage Permit (SUDP) for application, guidelines and other specific information. Contact the Department of Public Works at 303-446-3759 for additional details.
