Commercial Real Estate in Sloughhouse: Agricultural Zoning, Wineries and Rural Business Uses

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

Sloughhouse is a rural crossroads in southeastern Sacramento County, on Jackson Highway (State Route 16) between the Sacramento suburbs and Rancho Murieta. Its commercial potential is mostly agricultural: vineyards and wineries, farm stands, ranch and equestrian businesses, agricultural processing and, increasingly, utility-scale solar on grazing land. It is unincorporated, so Sacramento County’s agricultural zoning rules decide what a buyer can do. Confirm the zone, any Williamson Act contract and well, septic and road conditions for every parcel.

Who controls the parcel

There is no city or community services district for Sloughhouse. Land use falls under the Sacramento County Zoning Code and the County General Plan, with permits from County Planning and Environmental Review. Rancho Murieta, to the east, has its own services district; see our Rancho Murieta commercial guide. Check zoning on the County’s zoning map viewer.

Sloughhouse also gives its name to a federal wine region. The Sloughhouse viticultural area (27 CFR 9.201) was established by T.D. TTB-50, published July 17, 2006, and lies entirely within the larger Lodi viticultural area. Its boundary follows local roads including Alta Mesa, Wilton and Grant Line Roads and State Route 16 near Sloughhouse. It then follows Deer Creek northeast for about 11 miles to the El Dorado County line and returns along the El Dorado and Amador county lines and the Laguna estuary. A winery here can label wine with the Sloughhouse name if it meets federal sourcing rules.

Sloughhouse zoning for commercial, industrial and agricultural business

Most land around Sloughhouse is in the County’s agricultural and agricultural-residential districts, described in Chapter 2 of the Zoning Code. Business uses there are governed by the agricultural use standards in Chapter 3.

District	Intended uses	Business notes
AG-20, AG-40, AG-80, AG-160	Long-term farming on 20 to 160 acre minimum lots	Wineries, ag processing up to 5 acres, farm stands; food processing by Board use permit
AR-5, AR-10	Small farms with rural homes	Farm stands by right; ag processing up to 1 acre
AR-1, AR-2	Rural residential lots	Ag processing prohibited; farm stands need a use permit in AR-1
LC / GC	Retail and service commerce	Only where mapped, typically at crossroads
C-O Commercial Recreation	Active recreation in remote or water-oriented areas	Mostly by use permit

Wineries, farm stands and agricultural business

Small wineries and craft breweries (Section 3.4.8). These need a minimum three-acre site and a state ABC Type 02 or Type 23 license.

Production. Beer production is capped at 6,000 barrels a year in agricultural districts. Wine production over 2,500 cases needs a Zoning Administrator use permit if the site is within half a mile of an RD zone.
Tasting. Tasting is limited to five days a week unless the Planning Director approves a minor use permit, and food sales are limited to 15% of the tasting area.
Events. Event attendance scales with parcel size, from 50 people on 1 to 2.5 acres up to 350 on parcels over 20 acres. Larger events need a use permit.
Access. A shared private access road triggers a use permit unless every owner on the road consents in writing.

Large wineries and breweries (3.4.9). These follow the same standards without the production caps, but events in the AG-20 through AG-160 districts need a use permit.

Farm stands (3.4.7). Farm stands and agricultural markets are permitted by right in AG and most AR districts. Most products must come from the producer’s own crops, and non-agricultural goods are capped at 25% of the sales area. Buildings are limited to 1,500 square feet of indoor sales and 3,000 square feet enclosed. Each entrance gets one sign of up to 50 square feet and 6 feet tall.

Processing and stables. Primary processing of agricultural products is permitted by right on up to five acres in AG districts, with larger operations by use permit. Commercial stables need at least three acres.

Solar, Jackson Highway and other Sloughhouse rules

Solar. Grazing land around Sloughhouse is drawing utility-scale solar. The County’s Sloughhouse Solar Facility Final EIR, posted December 27, 2023, covers a 50-megawatt facility with storage and a substation on about 381 acres of grazing land. The site sits next to an existing solar facility, and power is to go to SMUD. We have not confirmed the project’s approval; for a landowner, such projects affect lease value and neighboring uses.

Jackson Highway. State Route 16 is a state highway, so new driveways or intensified access generally need Caltrans review in addition to County permits.

Lodging. Short-term rentals must follow the County’s STR rules, which require an on-site resident, and lodging pays the County’s 12% transient occupancy tax.

Transfer tax, business tax and property tax

Sloughhouse pays only the County documentary transfer tax of $0.55 per $500, per the Clerk-Recorder. A County General Business License is required for businesses located in the unincorporated area, per the Department of Finance. A change of ownership generally triggers Proposition 13 reassessment; land under a Williamson Act contract is assessed on its agricultural use, so confirm contract status.

Due diligence that matters in Sloughhouse

Start with our commercial due diligence checklist, then add:

Confirm the AG or AR district and minimum lot size on the County map.
For a winery or tasting room, check acreage, case or barrel volume, distance to RD zoning and road access.
Confirm any Williamson Act contract and its permitted uses.
Test well yield and septic capacity for any public-serving use.
Check flood zones near the Cosumnes River and Deer Creek.
Confirm Caltrans access rules for frontage on Jackson Highway.

Groundwater management crosses local service boundaries

Omochumne-Hartnell Water District identifies groundwater-management responsibilities in both the South American and Cosumnes subbasins, on opposite sides of the Cosumnes River. Its district history describes agricultural supplemental-water management and four flashboard dams now maintained for recharge. A Sloughhouse mailing address alone does not identify the applicable groundwater agency or water entitlement. Match the parcel to the agency boundary and request current fees, well records and any extraction requirements; a recharge project is not a promise of supply to an individual property.

Sources & notes

Note: We did not confirm which districts are mapped at specific Sloughhouse parcels, whether any commercial zoning exists at the crossroads, or the solar project’s approval. Agricultural tourism, B&B and home occupation rules in later Chapter 3 sections were not reviewed.
