Commercial Real Estate at Lake Berryessa: Marine Commercial Zoning, Reclamation Concessions and Resort Utilities

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

Commercial property around Lake Berryessa falls into two very different worlds. The shoreline and the marinas, campgrounds and resorts on it are federal land run by the Bureau of Reclamation through concession contracts, while the private parcels nearby, in communities such as Spanish Flat, Berryessa Highlands and Berryessa Estates, are under Napa County zoning. Confirm ownership, zoning and utility service for every parcel with Napa County and, for anything touching the lake, with Reclamation before relying on this page.

Who controls the parcel

There is no city at Lake Berryessa, so three sets of authorities share the area:

Bureau of Reclamation. Reclamation runs the federal lands and water, including the Dufer Point Visitor Center, the Oak Shores, Smittle Creek and Eticuera day-use areas, and the Capell Cove launch. Its August 31, 2026 operations release lists five concession-operated facilities: Markley Cove Resort, Pleasure Cove Marina, Steele Canyon Recreation Area, Spanish Flat Recreation Area and Putah Canyon Recreation Area. A business on federal land runs under a Reclamation contract, not a deed; buying one means taking over or bidding on a concession, which this page does not cover.
Napa County. Private land is zoned under Title 18 of the County Code. The County’s Chapter 12.08, adopted under Ordinances 1237 (2004) and 1287 (2007), adds local rules for the federal lake and park area, enforced by the Sheriff.
Utility districts. Water and sewer come from small special districts, not a city utility (see below).

Lake Berryessa zoning for commercial and resort use

District	Intended uses	Notes
MC Marine Commercial	Water-related commercial, recreation and services	For Berryessa, urban or rural residential land within four miles of the high-water shoreline, near crossroads on busier highways. Nearly every business use needs a use permit
CN Commercial Neighborhood	Local shops and services, with a broader list for Lake Berryessa and Capell Valley	Use permit for all commercial uses. ½-acre lots with public water and sewer, 1 acre without
CL Commercial Limited	Uses for tourists and highway travelers	Requires urban General Plan designation and frontage on a state highway or arterial. Lodging up to 50 rooms and restaurants up to 100 seats by use permit
AW Agricultural Watershed / AP Agricultural Preserve	Agriculture and watershed land around the communities	Wineries by use permit on large parcels
AH Affordable Housing combining district	Named housing sites, including Spanish Flat	Residential, not commercial; matters for mixed projects

We have not confirmed which of these districts is mapped on any particular Berryessa parcel. A 2021 Napa LAFCO report, cited below, describes two Spanish Flat parcels on Berryessa-Knoxville Road as zoned Marine Commercial and Agricultural Watershed.

What the County allows near the lake

Marine Commercial uses. Chapter 18.34, adopted by Ordinance 938 in 1989 and last amended by Ordinance 1456 in February 2020, lets only agriculture, simple parks and minor antennas in without a permit. With a use permit, MC land can host:

marinas, launch ramps and boat hoists
yacht and beach clubs
boat rental, sales, repair and storage, plus RV storage
marine and sporting goods retail, bait and fishing stations, fishing piers
restaurants of up to 50 seats, with no drive-through
charter and excursion boat docking, and fuel dispensing tied to an approved use
a deed-restricted commercial ADU for moderate-income or lower households

The Berryessa siting rules ask that MC sites avoid strip development and traffic hazards that cannot be mitigated.

Lot sizes and site rules. Restaurants need 20,000 square feet with public water and sewer, or an acre without. Other marine uses need 75 feet of water frontage, and the Planning Director sets the parcel size where public utilities are lacking. At least 20% of the site must be landscaped, outdoor storage must be screened, and height and setbacks come from the Section 18.104.010 schedule.

Berryessa-only CN uses. The CN chapter, amended most recently by Ordinance 1456, calls Lake Berryessa and Capell Valley isolated enough that residents need more than day-to-day shops. In those two areas only, a use permit can also allow:

auto supply stores
small contractor offices with screened equipment, boat and material yards
restaurants, cafes, coffee shops and pizza parlors of up to 50 seats, with no drive-through
hardware and building materials yards, including small ready-mix concrete plants capped at 3,500 cubic yards a year

Lake rules that affect a business

Under Chapter 12.08:

Selling on federal land. Selling food, goods or services in the lake and park area needs a Reclamation permit and must follow County health rules.
Docks. Building a dock requires Reclamation’s prior approval.
Passenger boats. Running a commercial passenger motorboat for hire requires a license and Reclamation authorization.
Dam area. No boating, swimming or skiing is allowed within 1,500 feet of Monticello Dam, and no parasailing within 2,000 feet.

Boat quarantine. Reclamation’s release says trailered boats must complete a free 30-day quarantine before launching unless they hold a Lake Berryessa green seal, can show decontamination, or are non-motorized or not trailered. It also reports the Capell Cove ramp closed indefinitely for staffing. Any boat storage, rental or service business should plan around those rules.

No vacation rentals. County Code Section 18.104.410 bars transient occupancy of dwellings in residential and agricultural districts, so short-stay lodging must be a permitted commercial use or a Reclamation concession.

Water, sewer and the 2020 fires

According to Napa LAFCO’s August 2, 2021 sphere of influence report:

Berryessa Estates. The Lake Berryessa Resort Improvement District provides water and sewer. The report describes it as fiscally distressed, with aging infrastructure that needs replacement.
Berryessa Highlands. The Napa Berryessa Resort Improvement District serves this area. About 110 homes within its boundary burned in the August 2020 Lightning Complex fires, which also damaged effluent spray fields.
Spanish Flat. A separate Spanish Flat Water District serves the area, and the 2020 fires destroyed most of its utility systems there.

The report’s staff recommendations are summarized here; the report does not record the final votes. Ask each district for capacity and a will-serve letter before planning any business that adds load.

Changing farm zoning. The same LAFCO report says rezoning the Agricultural Watershed portion of the Spanish Flat parcels would require a vote of the people under Measures J and P. The County’s Agricultural Preservation and Land Use Element says voters adopted Measure P in 2008 and that the Measure J/P policies cannot be changed without a public vote until after December 31, 2058. Treat any plan that depends on redesignating agricultural land as needing an election.

Transfer tax, business tax and property tax

Napa County’s document transfer tax page sets $0.55 per $500 of value and says the seller customarily pays in Northern California. No city tax applies in unincorporated areas. Ask the County Treasurer-Tax Collector about lodging tax and any business license requirement. A sale generally triggers Proposition 13 reassessment; possessory interests in federal concessions are assessed differently, so ask the Assessor.

Due diligence that matters at Lake Berryessa

Start with our commercial due diligence checklist, then add:

Confirm whether the land is private or federal, and for federal land, the concession terms.
Confirm the County zoning and General Plan designation, and pull every use permit.
Get a will-serve letter from the water and sewer district, or test the well and septic.
Check fire damage history and insurability after the 2020 fires.
For marine uses, confirm water frontage, dock approvals and Reclamation permits.
Check road access, since siting rules favor crossroads on busier highways.

Questions people ask

Can I buy a Lake Berryessa marina?

The marinas and resorts on the shoreline are federal concessions run under Reclamation contracts, so they are not bought like private land. Private Marine Commercial parcels nearby are a different matter.

Can I open a restaurant near the lake?

Possibly. CN and MC both allow restaurants of up to 50 seats by use permit, with no drive-through.

What is Marine Commercial zoning?

A Napa County district for water-related businesses such as marinas, boat rentals and storage, bait shops and small restaurants, nearly all by use permit.

Do I need Reclamation approval for a dock?

Yes. County Chapter 12.08 requires Reclamation’s prior approval to build a dock.

Who provides water and sewer?

Small districts: the Lake Berryessa and Napa Berryessa Resort Improvement Districts and the Spanish Flat Water District, depending on location.

Is there a transfer tax?

Only the County’s $0.55 per $500, customarily paid by the seller.
