Single-Room Occupancy Facilities


Single Room Occupancy (SRO) facilities are intended to provide housing opportunities in selected commercial zones for lower-income  one- or two-person households that cannot typically afford apartments. Development standards are intended to ensure affordability and to address neighborhood compatibility and facility management issues. 


Small and large SRO facilities would be allowed in the Limited Commercial (LC), Retail Business (C2), and Planned Community (PC) Zoning Districts. SRO facilities in the PC District are only allowed on sites that are designated commercial on the General Plan land use maps. 

Permit Requirements

Small SRO facilities (fewer than 10 units) are allowed as a permitted use and larger SRO facilities may be permitted with a use permit in commercial zoning districts LC, C2, C1 and medium- and high-density residential zones (R2, R3, and PC). Notification to property owners within 300 feet and a public hearing before the Board of Zoning Adjustments (BZA) are required procedures for the Use Permit. All SRO facilities are subject to design review.
