Hesperia FAQ
Do I have to live on the property to rent out my Hesperia ADU?
Not for a standard ADU. California Gov. Code 66314(a)(7), made permanent by SB 477, bars Hesperia from imposing owner-occupancy on standard ADUs. JADUs still require the owner to live in either the main house or the JADU.
Hesperia's code still mentions owner-occupancy - does that apply?
No. HMC 16.12.360(D)(5) is suspended by state law for standard ADUs and is not enforceable. Only the JADU owner-occupancy rule remains in effect.
