Mountain View FAQ
Can I run an Airbnb at a second home in Santa Clara County?
It depends on the city. Unincorporated Santa Clara County allows it where zoning permits transient lodging. San Jose, Mountain View, and Palo Alto restrict unhosted second-home rentals to night caps below 90 to 270 days yearly.
Do I need to pay county transient occupancy tax even if my city allows STRs?
Only unincorporated SCC charges a county TOT. Inside cities, you remit city TOT instead. Each platform collects automatically for most municipalities, but hosts remain responsible for verifying remittance and maintaining records.
San Jose FAQ
Can I list my San Jose investment property on Airbnb while away?
No. Unhosted short-term rentals are limited to your one primary residence. Investment properties and second homes cannot be registered for unhosted rentals under SJMC Section 20.80.140.
What documents prove primary residence in San Jose?
California driver's license, voter registration, vehicle registration, recent utility bills, and federal or state tax returns tied to the address are accepted by Planning during registration and audits.
