For more information on preservation easements, visit the San Francisco Architectural Heritage Web site or call Bill Beutner at (415) 441-3000, ext. 10. The Architectural Heritage is the only organization in the City with a preservation easement program, one of the largest in the western United States. In fact, they are a very helpful resource.
