Full Breakdown
100. 050(B) carves out a vacancy exception: if a mobile home is sold and stays on-site, the park owner may raise the rent for the new resident by up to 10% of the existing rent, implemented when the new resident first occupies the space or signs a rental agreement. 100(A). That resale increase is on top of, not instead of, other increases the chapter otherwise allows. 060, disclosing a rent schedule and other charges, and bars any rent ceiling adjustment where current registration is not on file.
This notice requirement is specific to mobile home space rent; it does not apply to ordinary residential apartment or house rentals, which fall instead under the statewide AB 1482 rent cap and notice rules.
Violations & Fines
Chapter 8.90 is enforced through the City Manager's administration of the rent ceiling and adjustment process rather than a standalone criminal penalty for a missing notice; § 8.90.105 lets the hearing officer deny any future rent adjustment to a park owner who has failed to comply with the chapter's requirements or with applicable state or local housing, health or safety law, which reaches a landlord who skips the required resale-increase notice.
