Design Review

Design review is the formal process by which a local historic preservation commission evaluates proposed exterior changes to properties in a designated historic district. The standard for approval is whether the proposed work is appropriate — meaning compatible with the historic character of the district and consistent with recognized preservation guidelines, most commonly the Secretary of the Interior's Standards for the Treatment of Historic Properties.

Land Use

In Practice

Design review applies to a wide range of exterior work including window and door replacements, siding and cladding changes, additions, demolition, solar panel installations, and mechanical equipment placement. Projects clearly compatible with the district's character may receive expedited administrative approval; more complex or potentially incompatible proposals typically require a public hearing before the preservation commission. A Certificate of Appropriateness from the commission must be obtained before a building permit can be issued for the work.
