Summary

Before Modesto mobile home park space rent can rise, Modesto Code of Ordinances Section 4-19.07(e) requires the Mobile Home Rent Stabilization Administrator to calculate and publicly post that year's allowable CPI-based increase by April 30, and requires each park owner to repost that notice inside the park within three days of receiving it.

(e)Notice of Allowable Annual Rent Increase.(1)Notice by Mobile Home Rent Stabilization Administrator.

Full Breakdown

07(e)(1). 07(e)(2), so residents see the figure directly rather than relying only on the city posting. 01(j) describe as guaranteeing residents no more than 90 days' notice of an increase. 11(o) requires the Administrator to mail the Hearing Board's written decision to the owner and all affected mobile home owners and tenants within 10 days.

Violations & Fines

Section 4-19.07(g) makes the sanction self-executing: an increase cannot lawfully be demanded, accepted, or retained until the required state-law notice has been given, so a park owner who skips it has no legal basis to collect the higher rent. If a resident is charged anyway, Section 4-19.21 makes that demand unlawful, and Section 4-19.22(b) allows a court to award damages plus a discretionary penalty of up to $500 or three times the damages, whichever is greater. The City Council may also bring a civil action under Section 4-19.25 to compel a park owner to follow the chapter's notice requirements.

Frequently Asked Questions

When does Modesto post the year's allowable mobile home rent increase?

By April 30 of each year, Section 4-19.07(e)(1) requires the Mobile Home Rent Stabilization Administrator to calculate the CPI-based figure and post it at the City's Tenth Street Place building and on the City's website, and to mail it to every non-exempt park owner and resident representative.

Do mobile home park owners have their own posting duty?

Yes. Once a park owner receives the Administrator's notice, Section 4-19.07(e)(2) gives them three days to post a copy in a prominent place inside the park so residents see the allowable increase without having to check the city building or website themselves.

Can a park owner collect a rent increase without giving notice?

No. Section 4-19.07(g) states the increase is not effective and cannot be demanded, accepted, or retained until the landlord has given the notice state law requires, which functions as an automatic block on collecting the increase until that notice goes out.

How much advance notice do residents get for a fair-return rent hearing?

At least 30 days. Section 4-19.11(i) requires the City to give written notice of the administrative hearing's time, date and place to the park owner and to a majority of affected residents before a fair-return petition can be heard.
