Hayward FAQ
Can I list a Hayward ADU on Airbnb?
Only for stays of 30 days or longer. California Government Code 65852.2(a)(6) and HMC 10-1.2740 prohibit ADUs from being rented under 30 days. Short-term rentals under 30 days violate Hayward zoning and the state ADU statute.
Is my Hayward ADU covered by rent control?
Usually not. The Hayward Residential Rent Stabilization Ordinance (RRSO) applies to multi-unit properties built before July 1, 1979 with at least five units under common ownership. An ADU on an owner-occupied single-family lot typically falls under the Costa-Hawkins single-family exemption, though statewide AB 1482 caps may still apply.
