Host Presence Rule: Rialto vs San Bernardino
How do host presence rule rules compare between Rialto, CA and San Bernardino, CA?
San Bernardino has fewer restrictions than Rialto.
Rialto, CA
San Bernardino County
Rialto has no short-term rental ordinance and therefore no host-presence (on-site host) requirement, no off-site local contact rule, and no 24/7 emergency contact mandate specific to STRs. Because STRs are not a recognized land use in Title 18, the code provides no framework distinguishing hosted from unhosted operation.

Rialto FAQ
Do I need to be on site when guests stay?
Rialto has not adopted a host-presence requirement because it has not adopted an STR ordinance at all. The threshold question is whether the use is allowed under Title 18 zoning, not whether the host is present.
Do I need a local emergency contact?
There is no STR-specific 24/7 contact requirement in Rialto Municipal Code. General nuisance enforcement under Ch. 9.50 (Noise) and Title 1 applies to the property owner of record.
San Bernardino FAQ
Do I need to live in my Joshua Tree STR?
No. Unincorporated SBC permits non-hosted whole-home rentals, but you must designate a local contact who answers calls within sixty minutes.
Can the local contact live elsewhere?
The contact must be physically able to reach the property within sixty minutes, so they typically live within the same desert or mountain community.
