New legislation is underway to protect California's mobile home parks, hundreds of which are affordable havens for low-income mobile home owners and tenants. Since 2000, owners and developers have targeted mobile home parks for conversion into higher-income generating uses, according to George H. Kaelin III, an attorney at Allen, Semelsberger & Kaelin LLP in San Diego. In 2007, Kaelin predicted that mobile home parks would face drastic decline and recommended that protections be put in place to mitigate these closures. He was right. Between 2000 and 2017, the number of mobile homes nationally has fallen 3%. Now, Assemblyman Mark Stone and advocates with the Golden State Manufactured-Home Owners League have put themselves to the task of protecting mobile home park residents from displacement with a statewide bill to limit park closures.
