Commercial Real Estate in Rutherford: Winery Use Permits, Pre-1990 Commercial Zoning and Historic Buildings

By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.

Rutherford is an unincorporated crossroads on Highway 29 between Oakville and St. Helena, and nearly every commercial property here is a winery, a tasting room or a vineyard. A small cluster of shops, a post office and historic buildings near the highway completes the picture. Napa County controls all of it, and its General Plan treats Rutherford as a place where new commercial land is essentially off the table. Confirm the zoning, the use permit and any historic status for each parcel with Napa County before relying on this page.

Who controls the parcel

With no city government, Rutherford falls under Napa County Title 18 and the County General Plan. The Agricultural Preservation and Land Use Element groups Rutherford with Oakville as pre-existing commercial areas designated for agricultural use:

• What is there. The element lists several shops, winery and tasting facilities, a post office, a historic grange hall and a former rail station that it reported vacant in 2006.
• Off the map. Neither community appears on the General Plan Land Use Map. The element says that effectively blocks new development, with little expected.
• 1990 zoning. Policy AG/LU-97 lets land zoned commercial as of February 1, 1990 be developed under that zoning as if mapped for it.
• Road safety. Policy AG/LU-98 supports safety and access work where Highway 29 meets Rutherford Cross Road.

Voter approval. According to the element, Measure J (1990) made converting agricultural land a matter for the voters, and Measure P, which voters adopted in 2008, extends that protection so the policies cannot be changed without a vote until after December 31, 2058. A buyer should assume Rutherford vineyard land stays agricultural.

Rutherford zoning for wineries and commercial use

Read the County zoning map for each parcel; we have not confirmed which Rutherford parcels carry commercial zoning.

Wineries under the Agricultural Preserve

The Agricultural Preserve that dominates Rutherford’s valley floor was California’s first, established in 1968, according to the General Plan element. Today’s AP chapter (Ordinance 511, 1976, as amended through Ordinance 1495 in 2024) works like this for wineries:

• Grandfathered wineries. Wineries and accessory uses that existed before July 31, 1974 may continue once their extent is confirmed, but any growth needs a use permit.
• New and expanded wineries. These need a use permit, as do crushing, bulk aging, bottling and storage.
• Visitors. Tours and tastings, art or historical displays and sales of wine-related products are accessory uses requiring a use permit.
• Other processing. Processing crops grown on the same or contiguous parcels needs a use permit. A processing building of up to 5,000 square feet may be allowed on 10 acres or more if it sells only on-site products.

Policy AG/LU-13 adds that, for wineries approved after the 1990 Winery Definition Ordinance, appointment tastings, sales of mostly Napa-grown wine, education and limited food service are treated as agricultural only while they stay accessory to production. The County’s winery standards in Chapter 18.104 also require 10 acres for a new winery and at least 75% Napa County fruit. They set road setbacks of 600 feet from the Highway 29 and Silverado Trail centerlines and 300 feet from other public roads, and cap accessory space at 40% of production area.

The Rutherford AVA and historic buildings

Rutherford AVA. The federal Rutherford viticultural area, at 27 CFR 9.133, was published July 2, 1993 (T.D. ATF-342) and took effect August 2, 1993. The petition described about 6,650 acres. Its southern line runs along Skellenger Lane, shared with Oakville, and its northern line is Zinfandel Lane. On the west it follows the 500-foot contour of the Mayacamas Range, and on the east it climbs toward the Vaca Range. The AVA governs wine labels, not land use, but it shapes the value of the vineyards and wineries inside it.

Historic reuse. The element allows owners of County landmark or National Register buildings in Rutherford and Oakville to seek approval for reuse if they rehabilitate and maintain the building to the Secretary of the Interior’s standards. That path matters for buildings like the grange hall or former rail station the element describes. Confirm any building’s actual listing status with the County before relying on it.

Existing businesses. Policy AG/LU-45 lets existing commercial establishments in commercial zoning continue in their buildings, add uses the zoning permits and include mixed residential-commercial uses. Policy AG/LU-46 lets nonconforming uses continue unless abandoned or found to be a nuisance, with rehabilitation allowed if intensity does not increase.

Restaurants and produce stands. Two voter measures noted in the element can matter on legacy parcels. Measure D (1998) lets qualifying historic restaurants add seats in existing buildings, and Measure K (2008) lets a produce stand parcel add a deli, outdoor barbecue and wine tasting.

No vacation rentals. Section 18.104.410 bars transient occupancy of homes in residential and agricultural districts, so visitor lodging needs a commercial permit.

Transfer tax, business tax and property tax

Napa County’s document transfer tax page gives $0.55 per $500, customarily paid by the seller in Northern California. There is no city tax in Rutherford. Ask the County about lodging tax and business licensing. A sale generally triggers Proposition 13 reassessment, and vineyard land under a Williamson Act contract is assessed differently.

Due diligence that matters in Rutherford

Start with our commercial due diligence checklist, then add:

• Read the winery use permit: production, visitors, marketing events, hours and grape sourcing.
• Confirm the parcel’s zoning, and whether commercial zoning dates from before February 1, 1990.
• Measure setbacks from Highway 29, Silverado Trail and Rutherford Cross Road before planning new buildings.
• Check historic listing status and Secretary of the Interior obligations for older buildings.
• Test wells and wastewater systems, and check for a Williamson Act contract.
• Confirm any nonconforming use has not been abandoned.
