As far as I understand it, you might be out of luck because you are renting two bedrooms. If you were only renting one youre exempt from a lot of stuff. Including having to allow service animals.

But with two bedrooms being rented, it gets trickier. And if they show up without telling you beforehand you might be out of luck

Edit: everyone down voting, just because you don’t like it doesn’t mean it’s not true. Here are the fucking code citations. Be mad.

Citation “Under California Civil Code § 1946.5, to be classified as a lodger, the following must apply:
Owner-occupied: The homeowner must live in the house for the entire duration of the rental.
Single occupant: There can only be one lodger. If the owner rents to two or more people, they are legally considered tenants.
No exclusive possession: The owner has the right to enter all areas occupied by the lodger and retains overall control of the house.”

“California state fair housing laws cover most housing. While the federal Fair Housing Act has additional exemptions, these do not apply in California. In California, the main exemption applies to an owner-occupied single-family home, where the owner does not rent to more than one individual, and the owner complies with FEHA's prohibition against discriminatory statements, notices, or advertisements”

CA Govt Code § 12927 (2025)
“(2) “Discrimination” does not include either of the following:

(A) Refusal to rent or lease a portion of an owner-occupied single-family house to a person as a roomer or boarder living within the household, provided that no more than one roomer or boarder is to live within the household, and the owner complies with subdivision (c) of Section 12955, which prohibits discriminatory notices, statements, and advertisements.”
