The Ideal Preservation Approach
The conversion of historic structures has the potential to diminish their historical and architectural integrity. Poorly executed conversions can also significantly devalue a property—potential buyers will avoid makeshift conversions. Before undertaking exterior alteration projects to implement the conversion of a structure, property owners should attempt to accommodate needed functions within the existing structure via interior modifications. When exterior modifications are necessary, their scope should be limited so that they do not significantly change the visual character of the existing structure and surrounding landscape. An attempt should be made to limit the visibility of any modifications from the street by placing them to the rear or on the sides of existing structures. Such modifications should conform to the guidelines provided in individual brochures covering alterations to the elements of historic landmarks and structures within historic districts.
Conversions of historic single family residences and other non-commercial structures to multi-family, commercial, or institutional structures require review by the Historic Preservation Commission. The more nearly a project conforms to the ideal, the more likely it is that the Commission will approve the project and issue a Certificate of Appropriateness.
Issues the Commission Will Consider When Reviewing Proposed Conversion Projects
· Whether alterations to a structure will preserve its historic character while accommodating new uses
· Whether required parking will be added so that it is not visible from the street
· Whether ADA access is to be provided to the rear or on the side of a structure so that it is near ADA parking and is less visible from the street
· Whether the size and placement of signs reflect the pedestrian character of a historic neighborhood.
· Whether historic front yard landscaping is to be maintained
· Whether a minimum of 5 feet of landscaping is to be maintained where pavement abuts a structure
