In a careful opinion, U.S. District Court Judge Jane J. Boyle determined that Ordinance 2952 was preempted by federal law. The Court resoundingly rejected the City's claim that it had the authority to regulate the residence of noncitizens within its borders. Noting that the City Building Inspector would be charged with interpreting and applying immigration information to prospective tenants, the court concluded that Ordinance 2952 “is an invalid regulation of immigration” and that the “Ordinance stands as an obstacle to the uniform application of federal immigration law[.]”
