Association with a significant historical event;

Association with historic figure;

Embodiment of distinctive characteristic of a type, period or method of construction;

Representative of the work of a master;

Significant or distinctive architectural or artistic value (including those structures that represent a significant and distinguishable entity whose components may lack individual distinction);

Archaeological significance; and/or

Inclusion on national register of historic places.

Every reasonable effort should be made to provide a compatible use for structures which will require minimum alteration to the building.

Rehabilitation should not destroy the distinguishing qualities or character of the structure. The removal or alteration of any historic material or architectural features should be held to a minimum, consistent with the proposed use.

Deteriorated architectural features should be repaired rather than replaced, wherever possible. In the event replacement is necessary, the new material should match the material being replaced in composition, design, color, texture, and other visual qualities. Repair or replacement of missing architectural features should be based on accurate duplication of original features.

Distinctive stylistic features or examples of skilled craftsmanship which characterize older structures and which often predate the mass production of building material should be retained wherever possible.

All structures should be recognized as products of their own time. Authorization to create an appearance inconsistent with the original character of the structure should be discouraged.

Contemporary design for new structures in historic districts and additions to existing structures or landscaping should not be discouraged if such design is compatible with the size, scale, color, material and character of the historic district, building or environment.

Consideration shall be given to detrimental impact and the financial hardship on the applicant affected by the application of historic preservation standards, and promoting less expensive alternatives when undertaking an alteration, improvement, rehabilitation or restoration of a structure.

Most properties change over time; those changes that have acquired historic significance in their own right should be preserved.

The Commission shall be guided for further details by the Secretary of Interior Standards for Historic Preservation Projects, prepared by the Office of Archaeology in Historic Preservation, United States Department of the Interior, Washington, D.C., as amended and supplemented.
