Putting a New Home on Your Land in Tuolumne County

10/13/2026

If you own a parcel in the foothills around Sonora, Jamestown or Angels Camp, a new manufactured or modular home can be a practical way to finally build on it. But rural land comes with its own questions: Can a truck get the home up your road? What kind of foundation will it sit on? And who signs off on the permits? Here's a straightforward look at how it works in Tuolumne County, and how Yosemite Homes in Jamestown helps landowners get from an empty lot to a finished home.

Start with the land, not the floor plan

It's tempting to pick a home first, but on foothill property the site usually decides what's possible. Yosemite Homes' process starts with a conversation about your goals, property, preferred home, budget and timeline. From there, their team reviews zoning, access, utilities, setbacks, grading and foundation needs on your parcel. They charge a $500 site evaluation fee, which their site says is fully credited toward your build if you move forward with them.

Site work depends on the property. On a rural lot it can include grading, excavation, utilities, septic, a well or driveway access. Yosemite Homes notes that site work isn't automatically included, and they spell out what is in your proposal, so you know where the line sits before you commit.

Getting the home up the hill

Delivery is where a lot of foothill buyers get nervous. Narrow roads, steep driveways and tight turns are part of life up here, which is why access is one of the first things checked during the site evaluation.

One Yosemite Homes customer put it this way: "We were worried that they wouldn't be able to get our home to our property, but they brought it up the hill seamlessly." — Janet Alexander

Every parcel is different, so if your road is steep or unpaved, bring it up early. It's much easier to plan driveway or grading work before the home is ordered than after.

Foundations on foothill lots

The foundation Yosemite Homes typically uses is a pit set foundation with a full slab and drain, which their site says meets or exceeds federal, state and local standards. Your actual foundation plan will depend on your parcel's slope and soil, which is part of what the site evaluation covers.

Who handles permits: Tuolumne County and California HCD

In California, two levels of government are involved.

The state's Department of Housing and Community Development (HCD) sets the rules for factory-built homes. According to HCD's permits and inspections page, factory-built housing is inspected at the factory before the state insignia is applied, and installation is subject to inspection by the local building department. HCD also notes that a C-47 contractor license is required for any contractor that installs or prepares for moving a manufactured home.

Locally, that means Tuolumne County. The county's Building Division, part of the Community Development Department, reviews building permit applications and oversees construction safety in the unincorporated area of the county. A separate division within Community Development handles land use and enforces the zoning ordinance, so it's worth confirming your parcel's zoning before you get attached to a particular home. A few practical notes from the county:

• Permits are issued to either owner-builders or licensed contractors, and the county asks would-be owner-builders to contact its Development Information Center before planning a major project.
• Building permit applications go through the county's online OpenGov permitting system.
• You can look up a property's zoning by address or Assessor's Parcel Number, but if your lot is inside Sonora city limits, the City of Sonora handles its land use designation.

Fees, required documents and timelines can change, so check with the county directly for your parcel. Yosemite Homes coordinates permitting and inspections as part of its project management, and handling the permit application itself is available for an additional fee.

A note for Angels Camp landowners

Angels Camp sits across the line in Calaveras County, so Tuolumne County's offices don't handle those parcels. If your land is near Angels Camp, check with the City of Angels Camp or Calaveras County about which office covers your parcel and what it requires. Yosemite Homes says it typically manages projects within a 30-mile radius of its service area, so reach out to confirm your location is covered.

Homes that fit foothill parcels

Once the site is understood, you can choose a home that suits it. Two 3-bedroom examples from Yosemite Homes:

The Caribou is a 3-bed, 2-bath home with 1,357 sq ft, measuring 23'8" x 60', listed at $197,200. See the Caribou.

The Sequoia is a 3-bed, 2-bath home with 1,459 sq ft, measuring 26'8" x 56', listed at $187,568. See the Sequoia.

Listed prices are for the home. Your total project cost depends on your site work, foundation, utilities and permits, which is exactly what the site evaluation is meant to pin down. Floor plans can also be adjusted. As customer Kathleen Burby said, "They helped me make changes to the floorplan and customize the home."
