Baldwin Park ties accessory dwelling unit fire sprinklers to the primary house. Municipal Code § 153.120.360(D)(1)(a)1. requires sprinklers in an ADU only when the primary dwelling on the same lot is already required to have them, rather than imposing an independent citywide mandate on every new unit.
