1. A property will be used as it was historically
or be given a new use that requires minimal change to
its distinctive materials, features, spaces, and spatial
relationships.
2. The historic character of a property will be
retained and preserved. The removal of distinctive materials
or alteration of features, spaces, and spatial relationships
that characterize a property will be avoided.
3. Each property will 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 elements from other historic
properties, will not be undertaken.
4. Changes to a property that have acquired historic
significance in their own right will be retained and
preserved.
5. Distinctive materials, features, finishes, and
construction techniques or examples of craftsmanship
that characterize a property will be preserved.
6. Deteriorated historic features will be repaired
rather than replaced. Where the severity of deterioration
requires replacement of a distinctive feature, the new
feature will match the old in design, color, texture,
and, where possible, materials. Replacement of missing
features will be substantiated by documentary and physical
evidence.
7. Chemical or physical treatments, if appropriate,
will be undertaken using the gentlest means possible.
Treatments that cause damage to historic materials will
not be used.
8. Archeological resources will be protected and
preserved in place. If such resources must be disturbed,
mitigation measures will be undertaken.
9. New additions, exterior alterations, or related
new construction will not destroy historic materials,
features, and spatial relationships that characterize
the property. The new work shall be differentiated from
the old and will be compatible with the historic materials,
features, size, scale and proportion, and massing to
protect the integrity of the property and its environment.
10. New additions and adjacent or related new construction
will be undertaken in a such a manner that, if removed
in the future, the essential form and integrity of the
historic property and its environment would be unimpaired.
