If a property is Locally Designated either as a Local Historic Property or within a Local Historic District, any and all proposed construction projects viewable from a public way, street, or place, must be reviewed by the Historic District Commission. The construction of a new building, the demolition of an existing building and/or all exterior modifications proposed to an existing designated structure must go through the Certificate of Appropriateness application process before construction is begun. Although basic building maintenance and certain other projects may be exempt from design review, it is always best to check with the Historic District Commission Office prior to starting a project.
