Design Review for Zone Lot Amendments

Landmark Preservation reviews applications for zone lot amendments to determine whether the zone lot combination or split adversely affects the character or integrity of the landmark or historic district.

Zone lots are the land designated as the building site for a structure; also, the land area occupied by a use or a structure. Zone lots provide a boundary for a defined area of land to which the Denver Zoning Code’s regulations for land uses and structures apply. Prior to new development, Denver zoning staff must confirm that a legal zone lot exists that meets zoning requirements in terms of size, dimensions, street frontage, etc. 

Please read the following instructions carefully to ensure timely review of your project.

2 - Collect submittal materials

3 - Staff review, revision and LPC/LDDRC presentation 

The Landmark Preservation Commission reviews zone lot amendments on individual landmarks and properties in historic districts except properties in the Lower Downtown Historic District, which are reviewed by the Lower Downtown Design Review Commission.

LPC/LDDRC review will result in a recommendation of approval, a recommendation of approval with conditions, continuance or denial.

  • Projects that are recommended for approval with conditions must make the requested adjustments to their final construction drawings before a certificate of appropriateness will be issued. 
  • Projects that are continued must provide additional information as requested by the LPC or LDDRC and must return to the LPC/LDDRC for approval.
  • Projects that are denied must go before the LPC/LDDRC again with a revised submittal that addresses the LPC's or the LDDRC's comments. 

4 - Certificate of Appropriateness issued

Once the project has been recommended for approval by LPC/LDDRC, landmark staff will issue a certificate of appropriateness and stamp the drawings.

The certificate of appropriateness and stamped drawings must be submitted to Development Services when applying for the zone lot amendment. If drawings submitted to Development Services vary in any way from the stamped drawings issued by Landmark staff, the permit drawings will need to be revised, the Landmark stamped drawings will need to be revised, or the project may need to return to the LPC/LDDRC for approval. 

Please coordinate with landmark staff on any changes.
