Buying a Home in Tuolumne County, CA: Transfer Tax, Rim Fire & Mining Disclosure

Site of the 2013 Rim Fire, a Gold Rush mining legacy with a real disclosure statute behind it, and a Yosemite-gateway short-term rental market with its own ordinance.

Tuolumne County, anchored by Sonora, is a Gold Country/Sierra foothill county and the site of the August 2013 Rim Fire — at the time one of the largest wildfires in California history, which burned deep into Yosemite National Park's northern reaches.

What’s the transfer tax in Tuolumne County?

Tuolumne County's documentary transfer tax is the standard statewide rate of $1.10 per $1,000 of consideration, with no city-level add-on.

Sonora — the county's only incorporated city — is a General Law city charging the standard $0.55 city-share rate on top of the $0.55 county rate, with no additional local surcharge, per the statewide rate survey effective December 1, 2025. Example: a $280,000 sale works out to $308 total transfer tax.

How did the 2013 Rim Fire affect Tuolumne County?

The Rim Fire burned 257,314 acres in Tuolumne County starting August 2013, including 78,895 acres inside Yosemite National Park's boundaries — one of the largest wildfires in California history at the time.

If you're looking at forested property in eastern Tuolumne County (Pinecrest, Twain Harte, and areas toward the Yosemite gateway), check current CAL FIRE Fire Hazard Severity Zone maps, since much of the burned area has since regrown vegetation that itself carries renewed fuel-load considerations, and confirm insurance availability early in your search.

Does Gold Rush mining history create a real disclosure obligation in Tuolumne County?

It can — beyond informal due diligence about historic mine workings around Sonora and other Gold Rush towns, California law creates a specific disclosure trigger: Civil Code §1103.4 (as amended by SB 110, effective January 1, 2012) requires a seller's Natural Hazard Disclosure package to include a "Notice of Mining Operation" if the property lies within one mile of an active mining operation reporting to the state's Office of Mine Reclamation under Public Resources Code §2207.

This covers active, reporting operations — not informal historic mine workings — so ask separately about any known abandoned shafts or tunnels before assuming clear rural land, and check county hazard mapping for a specific parcel.

Can I run a short-term rental near Groveland or Yosemite?

Groveland and eastern Tuolumne County function as a Yosemite National Park gateway market with real vacation-rental demand, and unincorporated Tuolumne County (which includes Groveland) regulates this directly under STR Ordinance Chapter 8.70.

Effective January 19, 2024, it is unlawful to operate or advertise a short-term rental (stays of 1-30 days) without a current Fire and Life Safety Inspection (valid two years) and a Transient Occupancy Tax certificate. The county has no permit cap and no residency requirement, but does require interior posting of local contact/evacuation information and standard smoke/CO alarm and fire-extinguisher compliance. Confirm current STR-ordinance compliance status for any specific property before assuming vacation-rental use is straightforward.
