Commercial Real Estate in Elk: Rural Village Zoning, a One-Well Water District and Coastal Permits

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

Elk is a tiny coastal village on Highway 1 in southern Mendocino County, perched above Greenwood Cove. Its commercial property is a handful of buildings: inns and bed-and-breakfasts, a store, a café or restaurant, galleries and a few mixed buildings. The water district counts just 14 commercial connections. Every project needs coastal review, and water and wastewater set hard limits, so confirm both for any parcel before relying on this page.

Who controls the parcel

Elk is unincorporated and entirely inside the Coastal Zone. Mendocino County applies its Coastal Zoning Code, and land use changes ultimately need Coastal Commission certification. Three local districts shape what a building can do:

• The Elk County Water District is the village’s only water provider. The 2025 LAFCo service review draft says it was formed on April 22, 1957, by Board of Supervisors resolution. The state CEQA record shows LAFCo filed an exemption for that review on March 5, 2025.
• The Elk Community Services District runs the Elk Volunteer Fire Department. The 2018 LAFCo fire sphere update says it was formed in 1990 and covers 57 square miles. It also owns the downtown community leach field property.
• The California Coastal Commission certifies land use changes and hears appeals.

See our Mendocino County commercial guide for countywide rules.

Elk zoning for commercial and visitor uses

The LAFCo review says a large share of the water district carries the General Plan’s Rural Village designation. The zoning map also shows rural residential, range and open space districts (RR5, RL 160, OS and PF). The village commercial uses fall under the coastal RV Rural Village district (Ch. 20.388), adopted by Ordinance 3785 in 1991.

The RV district’s purpose is to protect the village’s rural character while allowing neighborhood services and mixed uses. Section 20.388.060 names Elk among eight coastal villages where development must also meet the county’s visual resource criteria. RV lot size depends on services. Lots served by both water and sewer can be 6,000 square feet, lots with one service 12,000, and lots with neither 40,000.

Inns, B&Bs and cottage businesses

Visitor lodging is Elk’s main commercial use. The LAFCo review notes several B&B inns and vacation properties, and it describes the community as mostly second homes and short-term rentals. The water district bills B&B inns a share of a residential unit equivalent per guest room, so water charges scale with room count.

• Inns and B&Bs need a coastal development use permit in RV. Adding rooms is development that needs a CDP and a showing of water supply.
• Cottage industries. Under Chapter 20.452, a small business tied to the owner’s home is allowed by use permit in RV and the rural districts. It may have up to two outside employees, 1,000 square feet of space, 10 customers a day and one small unlit sign. Studios, small food producers and repair shops often fit this model.
• Transient occupancy tax. Lodging collects county TOT under Chapter 5.20. It sets an 8% base and authorizes an additional 2% approved in 1997, with one registration certificate per parcel. A Business Improvement District assessment is paid through the Treasurer-Tax Collector.

Water, wastewater and coastal permits

Water. The LAFCo review reports 102 developed parcels, 88 residential and 14 commercial, plus 18 customers outside the boundary. The district covers about 128 acres. It relies on one active well beside Greenwood Creek, with a standby well and rights on Greenwood Creek and Bonee Gulch. The treatment plant, built in 1979 and upgraded in 2002, is permitted for 42 gallons per minute. The review expects the six remaining buildable lots to fit within capacity, but a water-hungry new use deserves its own analysis. It also notes annual operating losses, no adopted capital plan and an 84,000-gallon tank due for replacement in 2026.

Wastewater. Most of Elk uses individual septic systems. A community collection line and leach field serves only about 10 downtown parcels, on property owned by the Elk CSD. A commercial building connected to that system has an advantage that is hard to recreate.

Coastal permits. The county’s Coastal Zone page says a Coastal Development Permit is required for development, which includes changes in how water is used or accessed. Processing typically takes six to twelve months, and owners must show an adequate water supply first. Build that into any escrow that depends on a change of use.

Transfer tax, business tax and property tax

The County Recorder collects documentary transfer tax and requires a Preliminary Change of Ownership Report with each deed. Its fee schedule does not post the rate, so confirm the amount on the escrow estimate. Elk has no city, so no city transfer tax applies. A sale generally triggers Proposition 13 reassessment. Lodging operators need TOT registration as described above.

Due diligence that matters in Elk

Start with our commercial due diligence checklist, then add:

• Get the Elk County Water District’s account terms, including any per-room charges for an inn.
• Confirm whether the building is on the downtown community leach field or a private septic system, and get its records.
• Order a county Letter of Zoning to confirm RV or other zoning and overlays.
• Pull the coastal development use permit for any inn, restaurant or store, and check its room and seat limits.
• Review bluff, landslide and visual resource constraints for oceanfront parcels.
• Confirm TOT registration and the Business Improvement District account for lodging.
