Yucaipa, CA Rental Property Rules: Rent Increase Notice (2026)

Yucaipa Municipal Code § 15.20.040(B) sets the order of steps for rent increases on mobilehome spaces in the City of Yucaipa, San Bernardino County, California. It sits inside the City Council's Mobilehome Park Rent Stabilization Program, Chapter 15.20, in the section on maximum permitted rent. This page covers mobilehome park spaces only, and spaces that qualify for an exemption under § 15.20.030 fall outside the chapter.

Step one is city approval. A park owner cannot send residents a rent increase notice first and ask the city afterward. The code says no notice of a rent increase can be given to residents until the increase has been approved under the chapter.

Step two is lawful notice. Once the city approves an increase, the owner cannot demand, collect or retain it until the affected residents have received lawful notice of that increase under the Mobilehome Residency Law, Civil Code Section 798 et seq. The length of the notice period comes from that state law, which the city section points to rather than restating.

Retroactive increases are not permitted. If the city-approved annual increase is not implemented by its effective date, the twelve month period before the next increase starts on the date of actual implementation, so a late rollout pushes the next increase back.

The approval itself runs through the rent administrator. For the annual adjustment under § 15.20.080, rent for a space can go up once every twelve months by the lesser of four percent of the current space rent as of the date of the complete application, or one hundred percent of the CPI increase in the preceding twelve months. Under § 15.20.105, the rent administrator mails written notice within thirty days saying whether an application is complete, and affected residents get twenty days from the mailing date to submit written responses. A park owner who fails to meet the registration requirements of § 15.20.073, including the annual statement due by January 31, loses the right to charge, collect, retain or apply for the increases the chapter allows.

Residents have a built-in defense. Under § 15.20.040(D), a resident can refuse to pay rent above the maximum permitted, and that excess is a defense to an action for possession or nonpayment of rent.
