The following regulations shall apply in the RU Residential Urban Zone:
A. Purpose. The regulations set forth in this section are designed to encourage the subdivision of small single-family residential lots for development with manufactured homes, including mobilehomes installed on permanent foundations, factory-built homes, or conventional site built homes. The small area and yard requirements are intended to facilitate the economical and flexible use of land, thus increasing the City’s stock of lower cost single-family housing. It is also the purpose of this zone to ensure that such developments are located in proper relationship to other uses and are compatible with those uses.
B. Use. (Amended by Ord. No. 173,492, Eff. 10/10/00.) No building, structure or land shall be used and no building or structure shall be erected, structurally altered, enlarged or maintained, except for the following uses, and, when a “Supplemental Use District” is created, for those uses as may be permitted in that district.

2. Side Yards. There shall be a side yard of not less than 3 feet in width on each side of a main building. The required side yard may be eliminated on one side of each lot, provided that:

4. Lot Area (Amended by Ord. No. 177,103, Eff. 12/18/05.) – Every lot shall have a minimum width of 50 feet and a minimum area of 5,000 square feet.

The following regulations shall apply in the “RMP” Mobilehome Park Zone:
A. Purpose. It is the purpose of the “RMP” Mobilehome Park Zone to encourage the provision of affordable housing in the City as provided in the Housing Element of the General Plan, by permitting both the retention and expansion of existing mobilehome parks and the establishment of new mobilehome parks. It is also the purpose of this ordinance to encourage the maintenance of the property for residential uses by allowing land zoned RMP to be used for single family dwellings. Because of the usual location of these lots in areas with industrial and manufacturing uses, the preservation of the property for single family residential use may require the variation from some of the standard housing requirements necessary or desirable in the rest of the City. Accordingly, the large lot minimum yard area requirements are necessary to ensure compatibility between single family residential uses and possible surrounding nonresidential uses.
B. Use. No building, structure or land shall be used and no building or structure shall be erected, moved onto the site, structurally altered, enlarged or maintained, except for such uses as may be permitted therein:
1. Mobilehome parks.
2. One-family dwellings.
3. Parks, playgrounds or community centers, owned and operated by a governmental agency.
4. Truck gardening; the keeping of equines, poultry, rabbits and chinchillas, in conjunction with the residential use of the lot, provided that such animal keeping is not for commercial purposes. (Amended by Ord. No. 181,188, Eff. 7/18/10.)

However, such structures may not exceed two stories in height. For the location of accessory buildings, refer to Sections 12.21 C. and 12.22 C.
7. Conditional uses enumerated in Section 12.24 when the location is approved pursuant to the provisions of said section.
8. Accessory uses and home occupations, subject to the conditions specified in Section 12.05 A.16. of this Code. (Amended by Ord. No. 171,427, Eff. 1/4/97, Oper. 3/5/97.)
