Henry Heater

Attorney Henry Heater was one of the founding members of Allen, Semelsberger & Kaelin LLP in 1987. His approach to litigation is complex and thorough, and he covers a variety of practice areas including:

Henry pioneered the use of failure-to-maintain (habitability) lawsuits against mobile home park owners in 1985, recovering $4.2 million for park residents in Agee v. Palmar. Since then, he has tried multiple failure-to-maintain cases, receiving a number of multimillion dollar verdicts. In 1985, Henry also successfully defended the first legal challenge to a California mobile home rent control ordinance. Since then, Henry has gone on to represent numerous cities and counties in successfully defeating challenges to their mobile home rent control ordinances. In addition, he has represented mobile home park residents with respect to park closings, and defended legal challenges to several mobile home park closure and conversion ordinances.

Henry has written and spoken extensively on mobile home park issues. He has taught a National Consumer Law course in mobile home law and was selected by the National Business Institute to teach a nationwide continuing legal education course to lawyers on manufactured housing issues. Henry has testified before the California Legislature on pending mobile home legislation on behalf of both the Golden State Manufactured-home Owners League (GSMOL) and the California Trial Lawyers Association.

Henry received a Bachelor of Science from the United States Air Force Academy in 1973. In 1981, he received a Juris Doctor from the University of San Diego School of Law where he was editor in chief of the San Diego Law Review. He has been named one of San Diego’s Best Lawyers by San Diego magazine and one of Southern California’s Top Lawyers by the Los Angeles Times.
