Does the park manager have the right to tell me to remove my belongings that are stored on my space?

The park manager has an obligation to keep the park safe from fire. According to California Code of Regulations, Title 25 (health and safety requirements for mobile home parks), Article 2, Section 1120, “Occupants shall keep the lot area and the area under, around, or on their unit and accessory buildings or structures free from an accumulation of refuse, rubbish, paper, leaves, brush, or other combustible material,” and that park operators “…shall ensure that a collection system is provided and maintained, with covered containers, for the safe disposal of rubbish.”
