A Residential Building Report (RBR) is required when any residential property changes ownership and should be obtained before the close of escrow. This includes single-family homes, apartment buildings, condominiums, and mixed-use buildings. It is important to obtain a report as early in the process as possible to ensure a completed report will be available in a timely manner. This will also allow sufficient time to resolve any identified issues. Please see the Mill Valley Municipal Code § 20.70.020.
