Discover 6.5 acres in the heart of Northern California wine country at 310 Franz Valley School Road in Calistoga. This property pairs a 1,488-square-foot, three-bedroom, two-bathroom residence with substantial shop and support facilities. Strategically located in northern Napa Valley near Sonoma County, it offers a potential regional base for businesses serving both counties and the broader North Coast.

Buyers can explore a regional headquarters or satellite location supporting office administration, project coordination, crew scheduling, equipment and materials storage, and mechanical service or repair. The residence may also offer potential for employee housing or accommodations for on-site management. For more than 60 years, the property served as the base of operations for a successful grading, paving, and utility construction operations company. The property includes a 2,643-square-foot mechanic shop, a 512-square-foot loft above the shop, and a 541-square-foot storage shop. An 816-square-foot steam pad accommodates steam cleaning of tools, equipment, and trucks, with a water collection and recycling system designed to prevent wash water from entering the ground. A dedicated used-oil storage and containment area is designed to prevent oil from leaking into the soil. Fuel storage includes 1,000-gallon gasoline capacity and 2,000-gallon diesel capacity. The office lease is transferable, with a purchase option also available. All proposed uses, including business operations and employee housing, are subject to applicable County requirements and property-specific approvals. Buyers should independently verify square footage, permitted uses, and lease or purchase terms.
