Civ. Code, § 800.47

Unless the homeowner specifically requests the service in writing from the management, a homeowner shall not be charged a fee for the entry, installation, hookup, or landscaping as a condition of tenancy except for an actual fee or cost imposed by a local governmental ordinance or requirement directly related to the occupancy of the specific berth where the floating home is located and not incurred as a portion of the development of the floating home marina as a whole. However, reasonable landscaping and maintenance requirements may be included in the floating home marina rules and regulations. The management shall not require a homeowner or prospective homeowner to purchase, rent, or lease goods or services for landscaping from any person, company, or corporation.
