10 rules for unincorporated Lassen County, California.
Verified from official government sources
Lassen County has no dedicated short-term rental ordinance for its unincorporated areas. There is no STR-specific permit. A vacation rental is treated as a use of the underlying property, so the controlling questions are the parcel's Title 18 zoning district and the county's general business and Transient Occupancy Tax rules.
Lassen County has no STR-specific noise rule, but it does have a countywide Noise Ordinance (Chapter 9.65, adopted by Ordinance No. 2021-004) that applies to all unincorporated property, including vacation rentals. It uses one-hour-average sound-level limits measured at the property line.
Lassen County imposes a Transient Occupancy Tax (TOT) on lodging in its unincorporated areas, collected by the County Treasurer/Tax Collector under Title 3 of the county code. This bed tax generally applies to short-term rentals. Confirm the current rate and filing schedule directly with the Treasurer/Tax Collector.
No short-term rental ordinance sets dedicated parking requirements for vacation rentals in unincorporated Lassen County. Parking is controlled by the general off-street parking standards in the Title 18 zoning code and by rules against blocking or parking in the county road right-of-way.
Lassen County has no short-term rental ordinance setting a guest-count cap for unincorporated vacation rentals. Occupancy is governed by general building and zoning standards for the dwelling, plus the California Building Code and any septic or water-system capacity, rather than an STR-specific maximum.
Lassen County imposes no insurance or liability-coverage requirement on short-term rentals, because it has no STR ordinance. There is no mandated minimum liability policy as a condition of operating. Carrying adequate coverage is strongly advisable but is a private and insurer matter, not a county mandate.
Unincorporated Lassen County sets no annual cap on the number of nights a property may be rented short-term, because it has no STR ordinance. There is no rented-nights limit; the relevant line is the Transient Occupancy Tax definition of a short-term stay (generally 30 days or less).
There is no short-term rental registration program in unincorporated Lassen County. The one registration that does apply is for the Transient Occupancy Tax: an operator who rents lodging to transient guests generally must register with the County Treasurer/Tax Collector to collect and remit that tax.
There is no host-presence or on-site-manager requirement for short-term rentals in unincorporated Lassen County, because the county has no STR ordinance. Hosts are not required to live on-site or designate a local contact, though a reachable contact is still a practical and good-neighbor measure.
Lassen County imposes no primary-residence requirement on short-term rentals, because it has no STR ordinance at all. Non-owner-occupied and investment vacation rentals are not prohibited by an STR rule; the only constraint is whether the use is allowed in the parcel's Title 18 zoning district.
