Yorkville, CA Real Estate & Homes for Sale
By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.
Yorkville is an unincorporated community in southern Mendocino County, California, on Highway 128 in the hills between Cloverdale and Anderson Valley, inside the Yorkville Highlands wine appellation. Property here is rural: homes on acreage, ranch land and vineyard parcels. ATTOM counted just 4 residential sales in the year to August 2025, its latest update and too few for a median; the nearest town figure is Cloverdale’s Redfin median of $589,219 for the three months to September 2026, and Mendocino County’s September median was $480,000 (C.A.R.).

A handful of sales a year can’t support a Yorkville median. ATTOM’s Yorkville page, last updated in August 2025, counts about 129 residential properties and 7 commercial ones in ZIP 95494, with 6 residential sales in 2024 and 4 in the year before the update (ATTOM). Its $456,300 median value is a model estimate, not a sale price. For a market benchmark, look to Cloverdale, the closest city, where Redfin’s median for the three months ending September 2026 was $589,219, and to Mendocino County’s $480,000 September median (C.A.R.). Neither describes a ranch with vines.

Yorkville property is priced by the acre, the water and the vines as much as by the house. We build comparables from ranch and vineyard sales across southern Mendocino and northern Sonoma County, then adjust for planted acres, well yield, road and the age and condition of the home.
The Yorkville Highlands appellation
Federal rules recognised the Yorkville Highlands American Viticultural Area in 1998 (27 CFR 9.159). Its boundary is drawn on six U.S. Geological Survey maps, including the Yorkville, Cloverdale and Hopland quadrangles. It begins at a survey benchmark on the Ornbaun Valley map and runs past the summit of Sanel Mountain and along part of the Mendocino-Sonoma county line.
The Yorkville Highlands growers’ association describes the appellation as about 40,000 acres straddling Highway 128 between Alexander Valley to the southeast and Anderson Valley to the northwest, at the headwaters of the Russian River and Navarro River watersheds. Its website, which carries a 2019 copyright, counts 24 vineyards and 414 planted acres, 83% of them red varieties, with vines between 850 and 2,500 feet and rocky soils of gravel and broken rock (Yorkville Highlands). Those figures come from a trade group rather than an agency and may not be current, so treat them as a guide. The valley’s online winery directory lists two wineries with Yorkville addresses (avwines.com, October 2026).
- Neighbouring appellations: the Anderson Valley AVA lies to the northwest, and the Pine Mountain-Cloverdale Peak AVA, created in 2011, crosses the county line near Cloverdale. A parcel’s appellation depends on where it sits against each boundary, so check the federal text rather than the listing.
- Before buying vineyard land: see our guides to buying a vineyard and how vineyards are valued.
Highway 128, Cloverdale and the county line
Highway 128 is the main road through Yorkville, running southeast to Cloverdale and Highway 101 and northwest into Anderson Valley. The growers’ association places the start of the appellation about five miles west of Cloverdale along the highway. Mendocino Transit Authority’s Route 75 serves Navarro, Philo and Boonville but has no Yorkville stop, so plan on driving.
Cloverdale is the nearest city, but crossing the county line changes the rules. Cloverdale is an incorporated Sonoma County city with its own water and sewer service and its own vacation-rental code. Yorkville follows Mendocino County rules: the county’s Planning and Building Services issues permits, only the county’s transfer tax of $1.10 per $1,000 applies at closing, and short stays carry Mendocino’s 10% transient occupancy tax plus a 1% lodging assessment. SMART lists a future Cloverdale train station but says it will be built “when funding becomes available” (SMART).
Buying ranch and rural land in Yorkville
Yorkville is thinly built: ATTOM counted about 129 residential properties in ZIP 95494 at its August 2025 update, and the appellation around them covers some 40,000 acres. Expect a rural parcel with a house rather than a house on a lot, and plan the checks around that.
- Water: expect a private well; we found no public water system serving Yorkville, and the state’s description of the Anderson Valley groundwater basin doesn’t mention Yorkville, so its well figures don’t carry over. Get the well log, a flow test, ideally late in the dry season, and a water-quality test, and ask how any vineyard or livestock is watered.
- Septic: pull the county septic permit, then have the system inspected. For land, budget for a site evaluation before you count on a building site.
- Roads: for any parcel reached by a road off Highway 128, get the recorded easement and any road agreement, and drive it after rain.
- Fire and insurance: on a ranch or vineyard parcel, the Fire Hazard Severity Zone comes first. Where it’s High or Very High, AB 38 has the seller hand over a defensible-space inspection from the six months before the sale, or both sides agree in writing that the buyer will get one within a year. Line up insurance quotes as soon as the offer is accepted.
- Neighbouring farms: with 24 vineyards in the appellation by the growers’ count, a home may sit beside a working vineyard or ranch, so ask what operations run next door and when.
On a ranch or vineyard parcel, have the water checked before you negotiate the price of the vines. A planted block without a dependable water source can be worth much less than its acreage suggests.

How Diamond Real Estate Group helps Yorkville buyers
A Yorkville purchase is usually land first. We confirm the appellation and parcel lines against the official descriptions, gather well, septic and permit records, review any grape contracts and planting history, check the fire zone and road agreements, and get insurance quotes before contingencies expire. We also compare ranch and vineyard sales on both sides of the county line, since a Cloverdale house price says little about a Yorkville ranch. See our Mendocino County guide and our vineyard property guide, and read how we work with buyers.
Selling a home in Yorkville
Cloverdale may be the nearest city, but Yorkville is in Mendocino County, and Cloverdale’s rules stop at the county line. Permit history is held by Mendocino County Planning and Building Services; septic and well files by its Environmental Health division.
Transfer tax
The documentary transfer tax is paid to Mendocino County at $0.55 per $500, with no city tax on top. A $700,000 ranch sale would owe $770. Sellers customarily pay in Diamond’s North Bay markets, but buyer and seller may split it differently; our transfer tax guide walks through it.
A land file for ranch and vineyard parcels
Most Yorkville sales involve acreage, so prepare records for the land as well as the house:
- Appellation. The Yorkville Highlands AVA is defined on six USGS maps, among them the Yorkville, Cloverdale and Hopland quadrangles. For a parcel near the edge, compare its location with that boundary and with the Anderson Valley line to the northwest.
- Williamson Act. A grazing or vineyard contract binds the buyer as successor owner. Share the contract early, and explain any nonrenewal notice already filed. Our Williamson Act page covers the basics.
- Water. Request the well completion report from Environmental Health, and assemble pump records and an account of how vines or livestock are watered.
- Access. Supply the recorded easement and road agreement for any private road off Highway 128.
Septic
Mendocino County does not require a septic inspection when a property changes hands, so any inspection is the buyer’s to negotiate. If the system is non-standard, the county code requires a valid operational permit for its use; make sure yours has not lapsed before you list.
Fire zone and statements
Look up the parcel’s fire hazard severity zone first. If it is High or Very High, AB 38 asks you to provide documentation of a defensible-space inspection made in the six months before the contract, or to sign an agreement making the buyer responsible for it during the first year of ownership. Where CAL FIRE is the inspecting agency, requests go through its online form. You will also give written smoke alarm and water heater statements and disclose any noncompliant plumbing fixtures.
For a price built from ranch and vineyard sales on both sides of the county line, request a home valuation.

Yorkville real estate FAQs
Where is Yorkville, California?
Yorkville is on Highway 128 in southern Mendocino County, in the hills between Cloverdale, in Sonoma County, and Anderson Valley. The Yorkville Highlands growers place the start of their appellation about five miles west of Cloverdale along the highway.
What county is Yorkville in?
Yorkville is in Mendocino County and is unincorporated, so the county handles zoning, permits and taxes. Cloverdale’s city rules stop at the Sonoma County line.
What is Yorkville’s ZIP code?
Yorkville is ZIP code 95494, the code ATTOM uses for its Yorkville property data.
What’s the population of Yorkville?
We didn’t find a Census Bureau population figure for Yorkville itself. The best measure of its size we found is ATTOM’s count of about 129 residential properties in ZIP 95494, last updated in August 2025.
How much do homes in Yorkville cost?
There are too few sales for a reliable median: ATTOM recorded 6 residential sales in 2024. For benchmarks, Cloverdale’s Redfin median was $589,219 for the three months to September 2026 and the Mendocino County median was $480,000 in September 2026; ranch and vineyard parcels are priced on their own terms.
Is Yorkville part of Anderson Valley?
For wine purposes, no. Yorkville sits in the Yorkville Highlands AVA, recognised in 1998, while the Anderson Valley AVA lies to the northwest, so a parcel between the two needs checking against both boundary descriptions. On the road, Highway 128 links Yorkville to Boonville and the rest of the valley.
How many vineyards are in the Yorkville Highlands?
The Yorkville Highlands growers’ association website (2019 copyright) counts 24 vineyards and 414 planted acres within an appellation of about 40,000 acres, with vines between 850 and 2,500 feet. Ask a listing’s seller for current planted acreage.
Is there a bus to Yorkville?
No. Mendocino Transit Authority’s Route 75 stops at Navarro, Philo and Boonville on its way to Ukiah but not at Yorkville, so a car is essential.
Can I rent out a Yorkville property to visitors?
Mendocino County rules apply, not Cloverdale’s vacation-rental code. As of October 2026 Mendocino County had not adopted inland short-term rental rules; its supervisors discussed creating them on February 3, 2026 and gave staff direction (county short-term rental page). Confirm the current rule with Planning and Building Services before you buy for rental income. Guests staying 30 days or less pay the county’s 10% occupancy tax plus a 1% lodging assessment.
What should I check first on Yorkville ranch land?
Water, then access, then fire. Get the well records and a flow test, the road easement and agreement, the fire zone and an insurance quote, and the septic permit, before you spend on vineyard or building plans.
Which transfer tax applies in Yorkville?
Only Mendocino County’s documentary transfer tax, $1.10 per $1,000 of the price. The rate matches Sonoma County’s, but the tax is paid to Mendocino County.
