Costa Mesa FAQ
Do I have to be present while guests stay at my Orange County STR?
No. Section 7-9-93 does not require host presence; unhosted whole-home rentals are allowed. You must, however, provide a phone number for the owner or a designee reachable at all times.
Who is the responsible contact if there is a problem?
The lease and the in-unit posting must list the property owner or a designee and a 24/7 phone number. The signed primary adult occupant is also legally responsible for compliance during the stay.
Santa Ana FAQ
Can I leave town while my hosted-share STR is occupied?
Hosted home-share permits require the host to remain on-site during the stay. Leaving town converts the rental into an unhosted use, which may exceed your permit class and trigger enforcement.
Who is the 24-hour contact?
A responsible local representative reachable any hour to respond within roughly an hour to neighbor complaints regarding noise, parking, trash, or safety at the STR property.
