Landmark Preservation reviews the designs of proposed exterior alterations, additions to buildings, new construction, signs, and non-vegetative site work for properties located within the boundaries of an historic district or for a property designated a Denver landmark. Design review ensures that a proposed project preserves key historic features and is compatible with the character of designated historic buildings, sites and districts.
The Landmark Preservation Commission, the Lower Downtown Design Review Board, and Landmark Preservation staff use design guidelines and the Secretary of Interior’s Standards for the treatment of historic properties to guide design review. Additional guidelines may apply for projects located in specific historic districts.
The Design Review page provides more detailed information about the Landmark design review process. Once a design review application is received, Landmark Preservation staff will evaluate applications for completeness within five business days, and let you know whether the project will entail an administrative or commission/board review process.
