Overview: Are Short-Term Rentals Allowed in Spring Valley, CA?

Short-term rentals are permitted in Spring Valley, CA, with important caveats. Spring Valley is an unincorporated community within San Diego County, which means it operates under San Diego County regulations rather than individual city ordinances. As of 2025, San Diego County has implemented restrictive but workable STR regulations that allow both hosted and non-hosted short-term rentals with proper permits and compliance.

The market has become more competitive due to recent regulatory changes that reduced the total number of permitted STRs.
