El Cerrito FAQ
How many guests can I host at my Contra Costa STR?
There is no county-specific numeric cap, but the California Building Code sets minimum square footage per occupant, and a common practice is 2 per bedroom plus 2 additional. Check your septic or sewer capacity for rural homes.
Can I host weddings or large parties at my STR?
Events beyond normal residential use may require a temporary event permit and are subject to noise, parking, and nuisance ordinances. Frequent large events are typically not permitted in residential zones.
Oakley FAQ
Can I rent my Oakley house to a group of 15 for a weekend?
Only if the home can legally accommodate 15 under building code egress, bedroom size, and septic or sewer capacity. Large events that generate noise or parking problems still violate Oakley's nuisance rules even if the headcount technically fits.
Can I put air mattresses in the living room to increase occupancy?
Rooms marketed for sleeping must comply with CRC R304 (minimum 70 sq ft) and R310 (egress window). A living room typically lacks a compliant egress window and should not be advertised as a bedroom.
