(A) Every reasonable effort shall be made to provide a compatible use for a property that requires minimal alteration of the building, structure, or site and environment or to use a property for its originally intended purpose.
(B) The distinguishing original qualities or character of a building, structure, or site and its environment shall not be destroyed. The removal or alteration of any historic material or distinctive architectural feature shall be prohibited.
(C) All buildings, structures, and sites shall be recognized as products of their own time. Changes that create a false sense of historical development, such as adding conjectural features or architectural features from other buildings, shall not be undertaken.
(D) Changes which may have taken place in the course of time are evidence of the history and development of a building, structure, or site and its environment. Those changes that have acquired significance in their own right shall be retained.
(E) Distinctive features, finishes, and construction techniques or examples of craftsmanship that characterize a property shall be preserved.
(F) Deteriorated architectural features shall be repaired rather than replaced. Where the severity of deterioration requires replacement of an architectural feature, the new feature shall match the old in design, color, texture, and other visual qualities and where possible materials. Repair or replacement of missing architectural features should be based on accurate duplications of features, substantiated by historic, physical, or pictorial evidence rather than on conjectural designs or the availability of different architectural elements from other buildings or structures.
(G) The surface cleaning of structures shall be undertaken with the gentlest means possible. Sandblasting, grinding or other cleaning methods that will damage the historic building materials shall not be undertaken.
(H) Significant archeological resources affected by a project shall be protected and preserved. If such resources must be disturbed, mitigating measures shall be undertaken.
(I) New additions, exterior alterations or related new construction shall not be discouraged when such alterations and additions do not destroy significant historical, architectural, or cultural material, and such design is compatible with size, color, scale, material, and character of the property, neighborhood and environment.
(J) 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.
(K) The quality of materials and craftsmanship used in a rehabilitation project must be commensurate with the quality of materials and craftsmanship of the historic building in question. Certain treatments, if improperly applied, or certain materials by their physical properties, may cause or accelerate physical deterioration of historic buildings. Inappropriate physical treatments include but are not limited to: improper tuckpointing techniques; improper exterior masonry cleaning methods; or improper introduction of insulation if damage to historic fabric would result. In almost all situations, use of these materials and treatments will result in denial of certification. Similarly, exterior additions that duplicate the form material and detailing of the structure to the extent that they compromise the historic character of the structure will result in denial of certification. For further information on appropriate and inappropriate rehabilitation treatments, owners are to consult the Guidelines for Rehabilitating Historic Buildings published by the National Park Service or contact the City Building Department. 'Preservation Briefs' and additional technical information to help property owners formulate plans for the rehabilitation, preservation and continued use of historic properties consistent with the intent of the Secretary's Standards for Rehabilitation are available from the State Historic Preservation Officer, the National Park Service regional offices and the City Building Department. Owners are responsible for procuring this material as part of property planning for a certified rehabilitation.
