Appendix C: Secretary of

the Interior’s Standards for

Rehabilitation

The Secretary of the Interior’s Standards for the Rehabilitation of Historic
Buildings are general rehabilitation guidelines established by the National
Park Service. These standards are policies that serve as a basis for the design
principles presented in this document. The Secretary’s Standards state that:
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 will 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 such a manner that, if removed in the future, the essential
form and integrity of the historic property and its environment would be
unimpaired.
