Document Description
Change of Zone No. 2600012 - ORDINANCE NO. 348.5056 is a proposed text amendment to Ordinance No. 348, the Riverside County Land Use Ordinance, that would update regulations for Additional Residential Accommodations, update mobile
home and manufactured home regulations and establish procedures allowing certain applications to be referred from the Director's Hearing to the Planning Commission. The amendment would reorganize Article XIXj (Additional Residential Accommodations), add Senate Bill (SB) 9 Units as a new housing type, and update development standards and procedures. The updated list of housing types
would include: (1) Accessory Dwelling Units. (2) Junior Accessory Dwelling Units. (3) SB 9 Units, (4) Second Units, (5) Guest Quarters, (6) Ranchets, and (7) Multiple Owner Group Units. The amendment would remove mobile home-specific development standards and apply the same development standards as other one-family residences, consistent with State law. This amendment also amends
administrative provisions in Article I to allow the Planning Director to elevate projects from a Director's Hearing to the Planning Commission as warranted. The proposed ordinance amendments would apply to all unincorporated areas of Riverside County.
