FPI managed federally subsidized housing. Federal regulations under that subsidy program required landlords to give 30 day notice before evicting tenants. FPI gave only three day notice. Plaintiffs sued under B&P Code 17200, claiming that FPI’s practice of giving too little notice before eviction was unlawful. This decision holds that the tenants had alleged a sufficient “loss of money or property” to have standing to sue under section 17200. FPI could comply with both state and federal notice requirements by giving 30 day notice and then on the 27th day giving a state notice of eviction. Even though plaintiffs remained in their apartments for more than 30 days after the 3 day notice that FPI served, they suffered a loss of property rights–they were no longer lawful tenants, and became tenants at sufferance without many of the rights of regular tenants. Plaintiffs have standing to bring suit under the UCL when they are subjected to an invasion of economic or property rights, or face imminent legal peril, even when they do not suffer actual out-of-pocket financial damages or loss of tangible property.
