Cal. Civil Code § 800.70

(a) The Legislature finds and declares that, because of the high cost of moving floating homes, the potential for damage resulting therefrom, the requirements relating to the installation of floating homes, and current government policy limiting the availability of floating home berths, it is necessary that the owners of floating homes within floating home marinas be provided with the unique protection from actual or constructive eviction afforded by the provisions of this chapter. (b) The management shall not terminate or refuse to renew a tenancy, except for a reason specified in this article and upon the giving of written notice to the homeowner in the manner prescribed by Section 1162 of the Code of Civil Procedure, to remove the floating home from the floating home marina within a period of not less than 60 days, which period shall be specified in the notice. A copy of this notice shall be sent to the legal owner, as defined in Section 18005.8 of the Health and Safety Code, each junior lienholder, as defined in Section 18005.3 of the Health and Safety Code, and the registered owner of the floating home, if other than the homeowner, by United States mail within 10 days after notice to the homeowner, addressed to the legal owner, each junior lienholder, and the registered owner at their addresses, as set forth in the registration card specified in Section 18091.5 of the Health and Safety Code.
