Demolition

Landmark Preservation staff review all applications for total demolition permits and for certificates of demolition eligibility (CDEs) citywide, including for structures that are not local landmarks or that are not in historic districts. This requirement helps preserve Denver’s history by providing the community an opportunity to protect buildings that prove to have historic, architectural, geographic or cultural significance.

Owners of non-landmark, non-historic-district properties who are not currently planning demolition but who want increased certainty about a potential future demolition may apply for a certificate of demolition eligibility (CDE), which involves a similar level of review. If a CDE is issued, a property owner or owner's agent may proceed with a demolition application without further review to the structure’s potential for designation for a period of five years. If you are in the due-diligence or entitlement planning process, we encourage you to apply for a CDE.

Properties that do not have potential to be an individual landmark are approved for demolition or granted the CDE. For properties that do have potential to be an individual landmark, notice of the demolition/CDE application is posted for 21 days. If a notice of intent to file a designation application is submitted to Landmark Preservation staff, the demolition application is paused. A facilitated stakeholder meeting must be held to discuss any potential options that do not entail demolition or designation of the property. If a review reveals that a property may qualify for historic designation, total demolition may not be allowed.

21 Days: August 24, 2026
60 Days: October 2, 2026
Timeline Extension to November 17, 2026

Landmark Preservation received a Notice of Intent to file a designation application for the property. The posting period for the property was extended to 60 days. On September 30, 2026, the Landmark Preservation Commission (LPC) approved a timeline extension proposed by the property owner and the residents who originally submitted the Notice of Intent to file a designation application. The posting period for the property will expire at 4:30 p.m. on November 17, 2026.  

If the posting period elapses and an application for historic designation is not received by Landmark Preservation staff, then a Landmark demolition approval will be issued on November 18, 2026. If an application for landmark designation, along with the applicable fee, is received, then the designation process will be followed.
