Santa Ana Municipal Code §41-1650 through 1657 allows for the adaptive reuse of nonresidential buildings into dwelling units, guest rooms or joint living and work quarters within 4 designated “project incentive zones” if the building either “was constructed in accordance with building and zoning codes in effect prior to July 1, 1974” or “has been determined to be a historically significant building.” The code also establishes development standards; allows for residential use in the project incentive zones regardless of underlying zoning; and gives alternative fire standards, building standards, and public works agency standards for adaptive reuse projects.
