Editor's note— Ord. No. 2017-16, § 2, adopted April 11, 2017, amended Chapter 3.32 in its entirety to read as herein set out. Former Chapter 3.32, §§ 3.32.010—3.32.090, pertained to similar material, and derived from prior gen. code §§ 2-74.0—2-74.9.

3.32.010 - Findings and purpose.

There is presently within the unincorporated area of the County of Alameda and the surrounding areas a shortage of space for location of mobilehomes. This has resulted in a low vacancy rate and rents have been and are presently rising rapidly and causing concern among a substantial number of residents. Because of the high cost of moving mobilehomes and the potential for damage resulting therefrom, the requirements relating to the installation of mobilehomes, including permits, landscaping and site preparation, the lack of alternative homesites for mobilehome owners, and the substantial investment of mobilehome owners in such homes, the Board of Supervisors finds and declares it necessary to protect the owners and occupiers of mobilehomes from unreasonable rent increases, while at the same time recognizing the need of the park owners to receive both a fair return on their property and rental income sufficient to cover increasing costs of repair, maintenance, insurance, employee service, utilities and government assessments.
