California's Noise Insulation Standards for Multi-Family Residential Construction

Requirements for noise insulation are included in the design of all new multi-family dwelling units to be constructed in California after August 1974. Noise Insulation Standards are part of the California Administrative Code (Title 25, Section 1092) and are enforced by local building departments throughout the state. The standards apply to all new multi-family dwelling units, such as hotels, apartments, duplexes, townhouses, and condominium units. Detached single-family dwellings are specifically excluded.
