Los Angeles County
Carson has no local ordinance limiting short-term rentals to a host's primary residence. The Carson Municipal Code does not condition transient lodging on owner-occupancy, length of ownership, or homestead status. State law (AB 1482 rent cap, Civil Code) likewise does not impose a primary-residence STR rule — that is a city-by-city policy choice Carson has not made.

Altadena FAQ
Can I rent out my Topanga vacation cabin while living in Pasadena?
No. The cabin must be your primary residence under Title 22.140.290. A vacation cabin where you live fewer than 184 days per year cannot be permitted as a short-term rental.
What proof of residency does the County accept?
California driver's license, voter registration, vehicle registration matching the address, federal or state tax returns, and recent utility bills. The Regional Planning Department may demand multiple documents during audits.
Carson FAQ
Must I live in the Carson home I rent out short-term?
No. Carson does not require STR operators to use the property as their primary residence. There is no owner-occupancy mandate in the Carson Municipal Code.
Can a corporation or out-of-state owner operate an STR in Carson?
Yes, under city law — Carson does not restrict operator type. The operator must still register for a Transient Occupancy Registration Certificate under CMC §6400 and obtain a city business license.
Does California state law force a primary-residence rule?
No. California has not enacted a statewide primary-residence STR requirement. That policy choice is left to each city — Los Angeles, Santa Monica, and West Hollywood require primary residence, but Carson does not.
