Sunnyvale FAQ
Can I list my Sunnyvale ADU on Airbnb?
No. California Government Code 65852.2(a)(6) and SMC Title 19 require ADU rentals to be 30 days or longer. Sunnyvale also has no citywide short-term rental program, so STRs are not authorized anywhere in the city. Sunnyvale Code Enforcement actively monitors Airbnb and Vrbo for non-compliant listings.
Is my Sunnyvale ADU subject to rent control?
Not local rent control - Sunnyvale has no rent stabilization ordinance. Statewide AB 1482 (Civil Code 1947.12) caps rent increases at 5% plus CPI annually with just-cause eviction protection. Individually-owned single-family homes with ADUs can be exempted from AB 1482 with proper written notice to tenants.
