Landmark Preservation reviews applications for additions on all Denver landmarks and historic district structures. Applications are reviewed for consistency with the appropriate design standards and guidelines. Please read the following instructions carefully to ensure timely design review of your project.
The following materials are not allowed in Denver historic districts or on individual landmark structures:
For more information about appropriate materials, please review the design guidelines in Step 1.
Your location and type of project determines which design standards and guidelines you should follow. If you are unsure about whether your project is in a historic district, check the landmark and historic districts map.
In certain neighborhoods and historic districts, additional design guidelines may apply.
The size and scope of your addition and its visibility from the street will determine how you proceed through the design review process.
Small additions - Administrative review - Pre-application meeting NOT required
If an addition is small enough to meet all of the following criteria, it may be approved administratively by Landmark Preservation staff:
If your addition falls under this category, you may submit your application (Step 3 below) without a pre-application review meeting.
Large additions - LPC/LDDRC review - Pre-application meeting required
Additions that do not meet the criteria above are subject to review by the Landmark Preservation Commission or Lower Downtown Design Review Commission. These additions include the following:
If your addition meets one of the conditions above, you must schedule a pre-application review meeting. To request a meeting, please submit the pre-application review form (PDF) and all required information to Landmark Preservation staff via email (email@example.com).
Rooftop (poptop) additions in historic districts where an RNO has completed design review training must present their proposal to the RNO before a complete applicaiton for the project may be scheduled for reviewed by the LPC. Landmark staff will let you know if there is a qualifying RNO in place and will make the referral at the time of your pre-application meeting.
For more information, download the Registered Neighborhood Organization policy (PDF).
Design review applications must adequately describe the project and provide sufficient information to evaluate the proposal. Documentation must clearly illustrate the existing conditions as well as any proposed alteration(s).
All applications for addition design review must include the following information:

Every project is different. Depending upon the complexity and specifics of your project, process and time frame may vary from the information presented on this website and in the application materials. If you have any questions, please contact us.
NOTE: All materials submitted with your application become the property the City and County of Denver. The materials are part of public record, can be used in a public hearing, and cannot be returned.
For eligible projects, as outlined in Step 2 above.
A - Staff will evaluate the completeness of your application and perform a preliminary design guideline evaluation within a few days. If necessary, staff will provide comments or request revisions.
B – If an application is found to be complete and meets the design guidelines, landmark staff will issue an approval within a few days. Projects that are approved will be issued a certificate of appropriateness (see Step 7 below). If a project cannot be approved administratively, Landmark staff will provide comments as to how it may be revised to meet the design guidelines or will let you know if it must be reviewed by the LPC or LDDRC.
The Landmark Preservation Commission reviews projects 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 approval, approval with conditions, continuance or denial.
Projects that are approved with conditions must submit the requested adjustments to the final construction drawings to landmark staff 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 LDDRC’s comments.
Once the project has been approved, landmark staff will issue a certificate of appropriateness and stamp the drawings.
The certificate of appropriateness and stamped drawings must be included with plans and materials submitted to Development Services when applying for building or zoning permits. If drawings submitted for a building permit vary in any way from the stamped drawings issued by Landmark staff, the permit drawings will need to be revised or the Landmark stamped drawings will need to be revised. If drawings submitted for a building permit vary substantially from the drawings approved by staff or LPC/LDDRC, the project may need to return to the LPC/LDDRC for approval. During the inspections process, the completed project must match the work shown on the Landmark-approved stamped drawings.
Please coordinate with landmark staff on any changes.
