REHABILITATION AND ADDITIONS 19 Rehabilitation and Additions to Contributing Structures The key to a successful rehabilitation is maintaining the characteristic details and historic fabric of a building. However, a successful rehabilitation may also involve repair or replacement of original building details or the introduction of new elements that can relate properly to the original components of the building and the neighborhood. This section recommends sensible rehabilitation treatments to ensure the typical elements of each style are preserved, as these elements contribute to the character of not only the building but also the neighborhood. Please note that for the purpose of “contributing structures” the term “should” as used within this document is intended to convey a suggestion or recommendation to the reader. It is not intended to communicate a requirement nor mandate. However, for “local designated” structures, these guidelines will be strictly enforced. The emphasis of this section is on rehabilitation, which is a compromise between remodeling, which has no sensitivity to the historic features of a building, and restoration, which is a more accurate but costly approach to repair, replacement, and maintenance. Buildings should not be made to look older or newer than they really are by using details from another style or period. This would alter both the building and the streetscape. Appropriate Rehabilitation The distinguishing original characteristics of an existing building, structure or site should be preserved. If replacement is necessary, the replacement feature should match the original feature in composition, color, texture, and other visual qualities. The application of non-traditional materials such as aluminum siding, vinyl siding, and metal frame windows (unless appropriate to the style) obscures the original character of the building and impacts the historic fabric of the neighborhood. When rehabilitating a building, an effort should be made to uncover previously encased or hidden finishes and details such as siding, stone, ornamental plaster or brick, and decorative structural elements such as pylons, beams and brackets. The encasing of original elements may in many cases lead to deterioration, and may detract from the building’s overall harmony within the neighborhood. The use of architectural elements and materials salvaged from demolition of historic buildings is encouraged. Before After Inappropriate Modifications DRAFT Before After

Rehabilitation and Additions to Contributing Structures The Secretary of Interior Standards are general principles that the Department of the Interior recommends for consideration in the planning stage of rehabilitation. The following subsections contain guidelines to assist property owners, who are planning the rehabilitation or expansion of a contributing structure, comply with the Secretary of Interior Standards. The salient points of these standards are as follows: (1) A property shall be used for its historic purpose or be placed in a new use that requires minimal change to the defining characteristics of the building and its site and environment. (2) The historic character of a property shall be retained and preserved. The removal of historical materials or alterations of features and spaces that characterize a property shall be avoided. (3) Each property shall be recognized as a physical record of its time, place, and use. Changes that create a false sense of historical development, such as adding conjectural features or architectural elements from other buildings, shall not be undertaken. (4) Most properties change over time; those changes that have acquired historic significance in their own right shall be retained and preserved. (5) Distinctive materials, features, finishes, and construction techniques or examples of craftsmanship that characterize a historic property shall be retained and preserved. (6) Deteriorated historic features shall be repaired rather than replaced. Where the severity of deterioration requires replacement of a distinctive feature, the new feature shall match the old in design, color, texture, and, where possible, materials. Replacement of missing features shall be substantiated by documentary, physical, or pictorial evidence. DRAFT (7) Chemical or physical treatments, such as sandblasting, that cause damage to historic materials shall not be used. The surface cleaning of structures, if appropriate, shall be undertaken using the gentlest means possible. (8) Significant archeological resources affected by a project shall be protected and preserved. If such resources must be disturbed, mitigation measures shall be undertaken. (9) New additions, exterior alterations, or related new construction shall not destroy historic materials that characterize the property. The new work shall be differentiated from the old and shall be compatible with the massing, scale, size, and architectural features to protect the historic integrity of the property and its environment. REHABILITATION AND ADDITIONS (10) New additions and adjacent or related new construction shall be undertaken in such a manner that, if removed in the future, the essential form and integrity of the historic property and its environment would be unimpaired. 20
