Downieville and the Gold Rush North Fork of the Yuba River, one of California’s smallest and most scenic mountain counties, extreme winter weather, and a tiny rental market where AB 1482 applies with no standalone MSA CPI
📍 County Seat: Downieville — Sierra County Superior Court 👥 ~3K residents — California’s 55th most populous county ⚖️ Superior Court • 100 Courthouse Square, Downieville, CA 95936
Sierra County is California’s least populous county by a wide margin, with a population of approximately 3,000 spread across a rugged stretch of northern Sierra Nevada terrain between Plumas County to the north, Nevada County to the west, Plumas and Nevada counties to the south, and Nevada state to the east. The county seat is Downieville, a small Gold Rush village of roughly 300 at the confluence of the North Fork of the Yuba River and Downie River — one of the most authentically preserved Gold Rush communities in California. Sierraville and Loyalton, in the Long Valley to the east, are the county’s other communities. Tahoe National Forest covers most of the county.
Sierra County’s rental market is one of the smallest in the United States for an incorporated county government. Downieville’s appeal to mountain bikers (the Sierra Buttes trail network is world-renowned) and river recreation enthusiasts, coupled with Loyalton’s saw mill, constitute the county’s primary economic activities beyond county government. The rental inventory county-wide may number in the dozens rather than hundreds. No rent control; AB 1482; no standalone MSA CPI. Extreme winter weather is the primary habitability consideration.

AB 1482 Coverage & CPI Index
Most Sierra County rental housing built before 2010 and not otherwise exempt is subject to AB 1482’s 5%+CPI rent cap (max 10%) and just-cause eviction after 12 months. Sierra County has no standalone BLS MSA. Verify the applicable CPI index with HCD guidance or a licensed California attorney before any AB 1482 rent increase. Key exemptions: units built within 15 years, SFRs/condos without corporate ownership (written notice required), owner-occupied duplexes. Expires January 1, 2030.
No Local Rent Control
No rent control in Sierra County as of early 2026. AB 1482 is the sole regulatory framework.
Extreme Winter Habitability
Downieville and the North Yuba River canyon receive significant annual snowfall; the surrounding Sierra Nevada terrain receives substantially more. Functional heating and weatherproofing are essential habitability requirements. Inspect heating systems before the snow season each fall. Respond immediately to heating failures in mountain winter conditions.
Mountain Biking & Recreation Economy
Downieville’s Sierra Buttes trail network is world-renowned in the mountain biking community, drawing visitors and some seasonally employed guides and trail crew workers during the recreation season (May–October). Seasonal recreation workers: annual W-2 or tax return documentation.
Loyalton Lumber Mill
The Loyalton lumber mill (Sierra Pacific Industries) is one of the county’s primary private employers, providing year-round W-2 employment for mill workers. Standard qualification applies.
🔥 Wildfire Risk
Sierra County’s forested Sierra Nevada terrain carries significant wildfire risk. Civil Code § 1941.8 applies to any declared disaster-affected properties. Insurance availability is constrained; verify fire coverage annually.
Very Small Rental Market
The entire county may have fewer than 100 rental units. Fair housing documentation and consistent qualification criteria are essential even in this micro-market.
SFR Exemption & Deposit Cap
SFR/condo exemption requires written notice. Security deposit capped at 1 month’s rent (effective July 1, 2024). Return within 21 days.

AB 1482 (Tenant Protection Act) requires just cause for evictions of tenants in place 12+ months. 3-day notice can only include rent - no late fees, utilities, or other charges. AB 2347 (eff. Jan 2025/2026) doubled tenant response time from 5 to 10 business days. Notice excludes weekends and court holidays.
Serve the required notice based on the eviction reason (nonpayment or lease violation).
Wait for the notice period to expire. If tenant cures the issue (where allowed), the process stops.
File an eviction case with the Superior Court (Unlawful Detainer). Pay the filing fee (~$385-435).
Tenant is served with a summons and has the opportunity to respond.
Attend the court hearing and present your case.
If you prevail, obtain a writ of possession from the court.
Law enforcement executes the writ and removes the tenant if necessary.

Eviction procedures can vary by county and may change over time. Local jurisdictions may have additional requirements or tenant protections.
For specific legal guidance, consult a qualified California attorney or local legal aid organization.
🔍 Reduce Your Risk Before Signing a Lease:
California landlords who screen tenants carefully before signing a lease significantly
reduce their risk of ending up in eviction court. Understanding
tenant screening in California —
including background checks, credit history, income verification, and rental references — is one of the most
cost-effective steps you can take to protect your rental property. Before you ever need California's
eviction process, proper tenant screening can help
you identify red flags early and avoid problem tenancies altogether.

Sierra County Landlord-Tenant Law: Downieville, World-Class Mountain Biking, and California’s Smallest County Rental Market
Sierra County has approximately 3,000 residents and likely fewer than 100 rental units county-wide — a rental market so small that describing it as a “market” in the conventional sense requires some imagination. Yet the legal framework governing those units is identical to the one governing San Francisco’s hundreds of thousands of rental units: California Civil Code §§ 1940–1954, AB 1482, and all the habitability, notice, and deposit return requirements that apply throughout the state. The county’s size does not reduce its landlord-tenant law obligations.
Downieville is one of California’s most remarkable small communities: a genuine Gold Rush village of 300 people in a river canyon where the North Fork of the Yuba River meets Downie River, with Victorian-era buildings, a one-room county courthouse, and an outdoor recreation economy built around the Sierra Buttes trail network that has made Downieville one of the world’s premier mountain biking destinations. The summer recreation season brings thousands of riders and their support economy through a community of 300 — an extraordinary seasonal concentration that creates hospitality and service employment with the same summer-peak income patterns documented for other California recreation counties.
Loyalton, in the Long Valley on the county’s eastern side, has a different character: a ranching and timber community centered on the Sierra Pacific Industries lumber mill, which is one of the county’s most significant private employers and provides year-round W-2 employment to mill workers and their families. Loyalton and Downieville are, in many ways, two different economic communities that happen to share a county government.
The AB 1482 CPI verification requirement, the no-MSA status, and the extreme winter habitability standard described for Plumas County apply equally here. Functional heating in Downieville during winter is a life-safety matter, not a maintenance preference.
