Lassen County, CA Short-Term Rentals: Registration Rules (2026)

Lassen County has not adopted a short-term rental registration or licensing scheme for its unincorporated areas, so there is no STR registry, annual renewal, or local rental number to obtain. The only registration that clearly attaches to a vacation rental is for tax purposes. The Lassen County Treasurer/Tax Collector is responsible for collecting Transient Occupancy Tax (TOT) on lodging in the unincorporated county, and California counties typically require an operator to register and obtain a Transient Occupancy Registration Certificate before, or shortly after, beginning to rent. Because Lassen relies on its general TOT chapter rather than an STR chapter, the registration steps, forms, and deadlines are set by the TOT ordinance and the Treasurer/Tax Collector's office rather than by a dedicated rental ordinance. Owners should contact the Treasurer/Tax Collector at 220 S. Lassen Street, Suite 3, Susanville, CA 96130 (phone 530-251-8218, email lcttc@co.lassen.ca.us) to confirm the current registration form, the certificate requirement, and the remittance schedule. Separately, the parcel's Title 18 zoning still governs whether the rental use is allowed at all; registration for tax does not by itself authorize a land use. No STR-specific registration fee or code section is published because the county has no STR ordinance.
