Buying a Home in Lassen County, CA: Wildfire Risk & Lassen Peak Volcano
Lassen Peak is one of the few volcanoes in the contiguous U.S. that has erupted in the last century — and fire has run directly at Susanville twice in the last several years.
Lassen County, anchored by Susanville, is a sparsely populated high-desert/volcanic-plateau county in California's northeast corner, home to Lassen Volcanic National Park and Lassen Peak — a monitored active volcano that most recently erupted in 1914-1917. The county has also seen a real, recurring pattern of large wildfires pushing toward Susanville itself in recent years, not just abstract regional fire risk.
What’s the transfer tax in Lassen County?
Lassen County's documentary transfer tax is flat across the entire county at $1.10 per $1,000 of consideration, with Susanville — the county's only incorporated city — imposing no additional surcharge on top.
Susanville sits at the same combined $1.10/$1,000 total as the rest of the county — the standard $0.55 county + $0.55 city split, not an add-on.
Is Lassen Peak an active volcano I should worry about?
Lassen Peak last erupted in 1914-1917 and remains classified by the USGS as an active volcano subject to ongoing monitoring, within Lassen Volcanic National Park in the southwestern part of the county.
This isn't a day-to-day concern for most property in the county — Susanville and populated areas sit at meaningful distance from the peak — but it's a genuinely distinctive geological fact for the region, and property closer to the park boundary should be understood in that context.
Has wildfire actually threatened Susanville itself?
Yes, twice in recent years. The Sheep Fire (August 2020) ignited in the mountains above Susanville and, before containment three weeks later, burned 29,570 acres and reached the edge of the city, destroying 26 structures (9 of them residences).
The following year, the Dixie Fire (2021) — the massive fire that also devastated neighboring Plumas County — came within about 6.5 miles of Susanville and burned back into the 2020 Sheep Fire scar, driven by the Susan River corridor's function as a landscape-scale wind tunnel between the Sierra and Cascade ranges. The broader 2020 fire season alone burned roughly 203,296 acres across seven large fires countywide. Check current CAL FIRE Fire Hazard Severity Zone maps for any specific property, particularly in the mountains and forested terrain surrounding Susanville, and treat wildfire insurance availability and cost as an early part of your due diligence.
What is rural life like outside Susanville?
Lassen County has a low population density and a high-desert/volcanic-plateau climate distinct from the forested Sierra counties to its south. Most residential property outside Susanville relies on private well water and septic systems.
As in other far-northern counties, expect longer response times for specialty trades.

Frequently asked
Does Lassen Peak being an active volcano affect buying property in the county?
It's mostly relevant only near the Lassen Volcanic National Park boundary — Susanville and most populated areas sit at meaningful distance from the peak. It's a real, monitored geological fact for the region rather than a day-to-day concern for most buyers.
How close has wildfire actually gotten to Susanville?
Close — the 2020 Sheep Fire burned to the edge of the city (29,570 acres, 26 structures destroyed), and the 2021 Dixie Fire came within about 6.5 miles. Check current CAL FIRE Fire Hazard Severity Zone maps and confirm insurance availability before buying in the surrounding mountains and forest.
Will my property have access to municipal water and sewer in Lassen County?
Outside Susanville, most residential property relies on private well water and septic systems rather than municipal utilities — confirm well/septic condition for any specific rural property.
