“I recently received a 90-day written notice of rent increase from my mobile park owner. However, this was delivered to me later than the actual date of notice. Is this notice still legal?”

-Jan Fenby, 38, mobile home park resident, Sacramento, CA


No, it is illegal for a notice of rent increase to be delivered late to a mobile homeowner. Mobilehome Residency Law (MRL) requires residents to receive a notice of rent increase at least 90 days before the date of the increase (Civil Code §798.30). Any notice required by the MRL must be sent in a manner that provides proof of delivery, such as in-person delivery, or by U.S. mail with postage prepaid (Civil Code §798.14).

Actual receipt of the notice less than 90 days before the increase is not a 90-day notice.


  • A 90-day advance written notice of rent increase is required.
  • The notice must be delivered in person or by U.S. mail.
