Best Real Estate Agents in Napa County (2026 Guide)
By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.
Disclosure: This guide is published by Diamond Real Estate Group, one of the brokerages listed. Our own broker is listed first so you know who wrote it. Every other agent is listed alphabetically; the order is not a ranking, and inclusion is not an endorsement.
Napa County fits five incorporated towns, a protected farm valley and a few remote rural districts into 748 square miles, so hire an agent who works regularly in the town or district where you’re buying or selling. This guide lists licensed agents whose own public profiles say they serve Napa County or its communities, and links each one to a state license record you can check.
County prices held up in 2026 while sales slowed: the September median for a single-family home was $918,000, up 2.0% from a year earlier, but closed sales fell 16.0% (C.A.R.).
How we chose the agents in this guide
We started with agents active in Napa County and kept only those we could verify: a current California real estate license on the Department of Real Estate public lookup (checked October 2026), a named brokerage, and a public profile that names Napa County or a community in it among the areas they serve. We don’t rank agents or report sales volumes, reviews or awards. Areas and specialties are as shown on each agent’s public profile or directory listing; we link profiles on agent and brokerage sites, not ranking or review sites. License status and brokerages change, so check the DRE record before you hire anyone, and interview more than one agent.

Census QuickFacts, 2020-2024 estimates.
Most of the county’s 132,949 residents live in its five incorporated places, and the City of Napa alone accounts for 76,562 of them (Census QuickFacts). The September county median slipped from $947,000 in August and sits just above the statewide figure of $899,720 (C.A.R.). Town medians spread much wider. In recent three-month windows, Redfin put the American Canyon ZIP code near $700,000, the City of Napa at $829,605, Yountville’s ZIP at $1,444,679 and St. Helena’s at $2,199,503. The up-valley figures rest on a few dozen sales, so read them as a direction, not a price for any single home.
Land rules explain much of that gap. The Agricultural Preserve, created in 1968 as the nation’s first, began with 23,000 acres and now covers more than 32,000, and a 1980 voter measure limits county growth to 1% a year (Napa Valley Vintners). As of January 1, 2026, 84,955 acres on 955 parcels were under Williamson Act contracts (Napa County Assessor), and winegrapes made up about 99% of the county’s farm production value in 2025 (Napa County). New subdivisions are rare as a result, and most housing sits inside the towns.
Angwin, Oakville, Rutherford and Pope Valley
We cover these four unincorporated communities here rather than in separate guides. A few agents in the table name them directly, and others serve them under Napa Valley or Napa County.
Angwin is home to Pacific Union College, . The college counts 8 miles to St. Helena and 27 to Napa (PUC). About 2,931 people and 939 housing units are spread over 4.8 square miles (Census Reporter), within the Howell Mountain AVA, whose boundary follows the 1,400-foot contour (eCFR). Read more in our Angwin guide.
Oakville and Rutherford are mid-valley wine districts. Both became AVAs in 1993, and the Oakville and Rutherford boundary descriptions both start where Skellenger Lane meets the Silverado Trail. Rutherford’s census place counts about 84 residents and 108 housing units (Census Reporter). With that few homes, sales here often involve vineyard land, which brings the county’s hillside and winery rules into play. See our Oakville and Rutherford pages.
Pope Valley is sparsely settled: its elementary school district covers 95.3 square miles with about 734 residents and 322 housing units (Census Reporter). The Pope Valley Store first opened in 1888 (Historical Marker Database), and the 2020 Hennessey Fire, which began August 17, burned the upper part of Hubcap Ranch while the lower ranch, a state historical landmark, survived (Napa Valley Register). Ask about the well, the septic system and who maintains the road; our Pope Valley guide describes the area.
County rules that shape what you can do with a property
- Nightly rentals: according to the 2019 Napa County Grand Jury report, short-term vacation rentals are prohibited in unincorporated Napa County, changing that would take a ballot measure under Measures J and P, and about 450 unpermitted rentals were operating. Each city sets its own rules.
- Hillside and creek work: under the Conservation Regulations (County Code chapter 18.108), earth disturbance on slopes over 5% needs an erosion control plan, and in mapped Agricultural Watershed woodland owners must keep 70% of the canopy that stood on June 16, 2016 (Napa County). Our Napa County vineyards guide covers planting.
- Wineries: since 1990, new or expanded wineries must source at least 75% of their grapes from the county, and a new winery needs a parcel of at least 10 acres (Napa County Grand Jury).
- Williamson Act land: contracts last at least 10 years, renew each year unless non-renewed, and require at least 10 acres of prime land or 40 acres of other farmland (Napa County Assessor).
- Transfer tax: the county charges $0.55 per $500 of value, and in Northern California the seller customarily pays it in escrow (Napa County Assessor).
- Fire: the 2020 Glass Fire burned 67,484 acres in Napa and Sonoma counties and destroyed 1,528 structures (CAL FIRE). Since July 1, 2021, sellers in High and Very High hazard zones must give buyers documentation of a defensible-space inspection done within six months before the sale contract, or the buyer and seller agree in writing that the buyer will bring the property into compliance within a year (State Fire Marshal).
- Groundwater: the state approved the Napa Valley Subbasin groundwater sustainability plan in January 2023, so well logs and production records belong in rural due diligence (California Natural Resources Agency).

Six things to settle with a Napa County agent
- Start with geography. Name the town or road and ask for the agent’s recent sales nearby, with addresses. A tract home in American Canyon and a vineyard parcel off the Silverado Trail share a county and little else.
- Ask whether the address is incorporated. Outside the five towns, county rules govern rentals, grading, wells and septic, and the agent should know which permits a property already holds.
- Ask where the water comes from. A city system, a small water district and a private well carry different risks. For a well, ask for the well log and recent production figures.
- Get fire and insurance answers early. Ask how the agent handles defensible-space paperwork and when they suggest collecting insurance quotes, ideally before you remove contingencies.
- For land and vines, ask about Williamson Act status, erosion control plans and any winery permits. Agents who list vineyard work appear in our vineyard and winery agents guide.
- Check the license. Each agent in the table links to a Department of Real Estate record that shows license status and the responsible broker.

Napa County agent FAQ
Do the agents in this guide cover the whole county?
Some do, and some focus on one or two towns. The last column of the table shows the areas each agent lists on their own profile, so use it to build a shortlist for your town.
Can I buy a home in Angwin or Pope Valley and rent it by the night?
Not under the county rules the 2019 grand jury described: short-term vacation rentals are prohibited in unincorporated Napa County, while rentals of 30 days or more are allowed. Confirm with the county before you buy.
How much is the transfer tax on a Napa County sale?
The county rate is $0.55 for each $500 of value, which comes to about $1,010 on a $918,000 home. The seller usually pays it.
Are homes selling quickly across Napa County?
It depends on the town. Redfin rated the American Canyon ZIP code “very competitive” with a Compete Score of 75, while St. Helena’s scored 18, “not very competitive,” with typical homes going pending in about 72 days.
