Commercial Real Estate in San Lucas: County Permits, Farm Business Uses and the Water Supply Question

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

San Lucas is a very small unincorporated farm community in the Salinas Valley, about ten miles south of King City. Commercial property here is limited to a few town lots, roadside and yard sites, agricultural processing and the surrounding farms. The deciding issue for almost any business plan is water: the local water district has struggled for years to deliver safe drinking water, and a change in who runs the system is under negotiation. Confirm zoning with Monterey County and service with the water district before relying on this page.

Who controls the parcel

San Lucas has no city government, so Monterey County’s Title 21 zoning code and the General Plan’s South County Area Plan govern land use. The area plan, adopted October 26, 2010 and amended as of March 7, 2025, does not name San Lucas, but its valley-wide policies apply. County Housing and Community Development issues permits.

Local services come from small special districts. The Monterey County LAFCO 2015 service review describes the San Lucas County Water District:

• Formation. It was formed in 1965 and covers about 93 acres.
• Water. It relies entirely on groundwater, and the original system dates to 1968.
• Sewer. Wastewater is treated in aeration ponds and a spray field on Highway 198, about a mile outside the district.
• Fire. At the time of the review, the South Monterey County Fire Protection District was in the process of annexing the San Lucas area. Confirm current fire service with the County.

San Lucas zoning for commercial and agricultural business

Confirm each parcel’s zoning string on the County map. Likely districts are:

Business uses that fit a farm community

Agricultural support. HC is the County’s zone for the businesses a farm town needs:

• Use permit. Agricultural processing plants, warehouses for farm products, contractor yards and trucking operations with repair and fueling.
• Administrative permit. Tradesmen’s shops, auto repair and small mini-warehouses.

The chapter’s height limit is 35 feet unless the zoning map sets a lower one. Ordinance 5422, adopted August 27, 2024, last amended the HC use lists.

Neighborhood commercial. In LC, a market, hardware store, salon, small bank or office needs an administrative permit. A restaurant or service station needs a use permit. The County requires a General Development Plan for LC sites over an acre or with more than one use. A change of commercial use that keeps the same nature and intensity needs no permit at all, which helps when re-tenanting an existing storefront.

Alcohol. Any alcohol service or live entertainment within 200 feet of a residential district boundary requires a use permit. That distance reaches most lots in a small town.

Housing above shops. LC allows residential space by use permit if it does not exceed the commercial floor area.

Water supply: the key due diligence item

The water history shapes what any San Lucas property can support.

• Do-not-drink order. LAFCO’s review reports that the County Health Department issued a do-not-drink order in July 2011 after nitrate levels exceeded standards. Residents relied on bottled water for more than three years until a nearby ranch drilled a compliant well in December 2014.
• Ongoing violations. A State Water Board letter of September 5, 2025 found the system had not consistently provided safe water for several years. It cites nitrate spikes in its single well during irrigation seasons from 2016 to 2021 and a 2023 compliance order over the treatment plant. The system then had 94 connections.
• Proposed consolidation. In June 2025 the district board voted to pursue managerial consolidation with California Water Service’s King City system. The State Water Board set a negotiation deadline of March 5, 2026. If no voluntary deal is reached, the Board may order consolidation after making required findings. That outcome was pending when the letter was written.
• February 2026 update. A State Water Board public meeting FAQ dated February 26, 2026 says the board’s June 10, 2025 choice pairs a new second well in San Lucas, with wellhead treatment, with managerial consolidation under Cal Water. Under that plan, district customers would become Cal Water customers, and wastewater would stay with the district. The FAQ estimates construction finishing around the first quarter of 2030. It lists the timeline, rates, funding and cost-sharing as still open, so confirm the current status with the district and the State Water Board.

For a buyer, this means water service terms, connection fees and rates may change. A will-serve letter matters more here than almost anywhere in the county.

Valley-wide policies and short stays

• Floodways (SC-5.3). New development may not encroach on the Salinas River’s main channel and floodway.
• Recharge areas (SC-5.1). Groundwater recharge areas are protected from new development.
• Oil and gas (SC-3.1). The area plan bars new oil and gas wells in every designation, which limits any energy-related use on surrounding land.
• Lodging. Motels need a use permit in LC. Short stays of 30 days or less inland may need a County permit under its short-term rental rules. Operators collect the County’s 10.5% transient occupancy tax.

Transfer tax, business tax and property tax

Monterey County Code Chapter 5.32, rewritten by Ordinance 5211 in 2012, imposes $0.55 per $500 of consideration over $100, with liens that remain excluded. No city tax applies. Ask the County Treasurer-Tax Collector whether a county business license applies. A sale generally triggers Proposition 13 reassessment.

Due diligence that matters in San Lucas

Start with our commercial due diligence checklist, then add:

• Confirm the zoning string and whether a General Development Plan applies.
• Get written water service confirmation, and ask about the status of the Cal Water King City consolidation and any rate or fee changes.
• Confirm sewer capacity at the district’s ponds for any use that adds wastewater.
• Pull use permits for food service, alcohol, processing or yard uses.
• Order a flood determination for parcels near the Salinas River.
• Confirm fire district coverage and any fire-flow requirements for a new building.
