A federal judge dismissed a lawsuit against the city of Petaluma by owners of two mobile home parks who claimed the city infringed on their constitutional rights. Owners of the senior-only Youngstown on North McDowell and all-ages Little Woods Mobile Villa on Lakeville Highway claimed the city’s rent control laws as well as its park closure regulations infringed on their rights because owners are forced to operate parks at a loss. The lawsuit was dismissed last Tuesday by Judge Charles R. Breyer of the Northern California District Court.
