Castro Valley FAQ
Is there a limit right now in unincorporated Alameda County?
No countywide numeric cap exists; regulations may change, so check with the Community Development Agency before heavy hosting.
How is hosted versus un-hosted defined?
Hosted typically means the primary resident remains on-site during guest stays; un-hosted means the whole home is rented without the resident present.
Fremont FAQ
Does a one-night stay count the same as a week?
A cap typically counts total rented nights, so a 7-night booking counts as 7 nights against the cap regardless of guest count or booking size.
Can I split a property into multiple STR listings?
No. The night cap applies to the property and operator together, and multiple listings of the same unit are consolidated for cap enforcement.
