Rehabilitation

Rehabilitation is a form of treatment applied to historic properties that acknowledges the need to alter or add to a historic property to meet continuing or changing uses while retaining the property's historic character.

The Secretary of Interior's Standards for the Treatment of Historic Properties (codified in 36 CFR 67 for use in the Federal Historic Preservation Tax Incentives program) define rehabilitation as "the process of returning a property to a state of utility, through repair or alteration, which makes possible an efficient contemporary use while preserving those portions and features of the property which are significant to its historic, architectural, and cultural values."

Other forms of treatment include preservation, restoration, and reconstruction.
