What is a District?

Local Historic Districts

Historic district designation is an overlay zone that applies to entire neighborhoods or other areas that include multiple properties.  Designation is an honor, meaning the community believes the architecture, history, and character of the area are worthy of recognition and protection.  Zoning provides controls on the appearance of existing and proposed buildings.  Historic districts can help stabilize and improve property values, while protecting property owners from inappropriate changes that may destroy the special qualities of their neighborhood.   Unlike landmark designations, local historic district designation has no effect on local property taxes for property owners within the designated district.


Owners wishing to change the design or materials of the exterior of their landmarks or district properties, go through a design review process by the Historic Preservation Commission called a Certificate of Appropriateness (minor works done in accordance with Commission Guidelines may be approved by staff).
