Summary

Whittier requires every owner of a covered mobilehome park to register each rented or rentable space with the city every year by September 30 and pay a ninety-dollar per-space fee. Missing the deadline adds a ten percent penalty on the unpaid balance and voids any rent increase until the account is current.

On or before September 30th of each year, a mobilehome park owner must register each mobilehome space that is rented or available for rent with the city on a form approved by the RAA. ... Initial registration fees are hereby established as ninety dollars per mobilehome space and may be amended by resolution of the city council. ... Any mobilehome park owner who fails to pay the annual rental registration fee on or before September 30th shall be assessed a penalty in an amount equal to ten percent of the unpaid balance for each mobilehome space, including the unpaid balance remaining from unpaid rental registration fees and/or penalties from prior years.

Full Breakdown

080 requires a mobilehome park owner to register each mobilehome space that is rented or held out for rent with the city, on a form the Rent Arbitration Administrator approves, on or before September 30 each year, and to report any changes or discovered errors within thirty days. The registration must disclose the current rent and date of the last increase for each space, the owner's name and contact information, the number of spaces in the park, each mobilehome owner's name and mailing address, a site map, move-in and vacancy dates, and a description of the housing services provided; the Administrator can also require registration of all housing services offered.

The initial fee was set at ninety dollars per mobilehome space, subject to change later by council resolution, and spaces exempted under the chapter's state-law exemptions owe no fee. A park owner may pass through up to half of the registration fee to mobilehome owners, but only if the annual registration was filed accurately and on time, the pass-through appears as its own line item, mobilehome owners get thirty days' notice, and the charge is collected in twelve equal monthly installments.

Violations & Fines

Section 9.20.150 penalizes a park owner who misses the September 30 deadline with a charge equal to ten percent of the unpaid registration balance per mobilehome space, layered on top of any unpaid balance carried over from prior years, though the Rent Arbitration Administrator can waive the penalty for good cause shown in a written application. Until the fee and any late penalty are fully paid, any rent increase for that space is unenforceable and void under Section 9.20.150(B). Separately, Section 9.20.130 authorizes an administrative fine of up to one thousand dollars for violating Chapter 9.20 or the Administrator's procedures, and Section 9.20.140(C) allows criminal misdemeanor prosecution carrying up to a one-thousand-dollar fine, six months in county jail, or both.
