Graton, CA Real Estate & Homes for Sale
By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.
Graton is an unincorporated village of about 1,800 people in west Sonoma County, California, between Sebastopol and Forestville, with 767 housing units on 1.6 square miles. The Census Bureau puts the median value of its owner-occupied homes at $878,100 (2020–2024 survey). The county sets the rules, and a local services district runs the sewer. The Graton Resort & Casino, despite the name, isn’t in Graton: it has a Rohnert Park address.

Graton sales are too few for a dependable monthly figure. Redfin’s ZIP 95444 median of $968,000 for the three months to June 2026 was 25.6% lower than a year earlier, and the same page lists only three homes sold (Redfin). The Census estimate is steadier but older: owners valued their homes at a median of $878,100 across the 2020–2024 survey, with a wide margin of plus or minus $52,413 (Census Reporter).

Who sets the rules in Graton?
Graton is a census-designated place, not a city, so Sonoma County is its local government. Permit Sonoma handles zoning, building, well and septic permits; the county’s 12% transient occupancy tax, vacation rental rules and tenant protection ordinance apply; and a sale pays only the county’s documentary transfer tax of $1.10 per $1,000. Graton’s sewer is run by its own public agency, the Graton Community Services District.
A 95444 mailing address doesn’t tell you whether a parcel is inside the sewer district or how it’s zoned, so look the parcel up in Permit Sonoma’s records before you rely on either.
Sewer from the Graton Community Services District
Graton’s sewer system started as a county sanitation zone in 1976, passed to the Sonoma County Water Agency in the mid-1990s and became the locally governed Graton Community Services District on July 1, 2004. Sonoma LAFCO’s review that year described a service area of about 260 acres, matching the county’s urban service area for Graton, with about 637 equivalent single-family connections and two lift stations (Sonoma LAFCO).
- Treatment: the plant at 4950 Ross Road was designed for secondary treatment of 140,000 gallons a day and was treating about 100,000.
- Discharge: from October 1 to May 14, treated water went to Atascadero Creek, a Russian River tributary; in summer, recycled water irrigated land along the pipeline to Forestville, which also gave Graton’s effluent its final, tertiary treatment.
- Cost and capacity in 2004: the average charge was $795 a year, which LAFCO called “somewhat high for Sonoma County,” and the plant had room for about 270 more connections, short of what full buildout under the General Plan would need.
Those figures are from 2004. Before you buy in Graton, ask the district for the current sewer charge, confirm the parcel is connected or can connect, and, if you plan an ADU or addition, ask whether capacity and connection fees allow it. Outside the district, plan on a septic system, which the county doesn’t require anyone to inspect at sale.
Where does Graton’s water come from?
Permit Sonoma’s water and sewer referral list names no water provider for Graton and notes that properties not served by a listed agency may be on a well (Permit Sonoma). In practice, that means confirming the source for each address: a private well, a shared well or a small water system. Ask for the well log, a recent flow test and water-quality results, and for a shared system, the written agreement on repairs.
County well rules changed in 2023, and new wells now face added review in some areas. In March 2025, a court temporarily stayed an order that would have suspended non-emergency well permits, and the county says it will alert the public if that changes (Permit Sonoma). If a property needs a new or replacement well, check the current status before you count on drilling one. Our wells, septic and rural utilities guide covers the inspections.
Graton Rancheria and the casino: what’s actually in Graton
The name causes confusion, so here are the facts. The Federated Indians of Graton Rancheria, a federation of Coast Miwok and Southern Pomo groups, take their name from a 15.45-acre tract in Graton that the federal Bureau of Indian Affairs bought in 1920 and held in trust. Congress ended the tribe’s federal recognition in 1958 under the California Rancheria Act, and recognition was restored on December 27, 2000 (Federated Indians of Graton Rancheria).
The tribe’s Graton Resort & Casino opened in November 2013. It has a Rohnert Park address, 288 Golf Course Drive West, and sits on the tribe’s reservation just outside that city (Graton Resort & Casino). The casino doesn’t sit in Graton, and Graton’s own homes, sewer district and county rules have nothing to do with it.
The village, the West County Trail and the bus
The county’s urban service area for Graton, the boundary that matches the sewer district, is where the General Plan directs Graton’s sewer-served growth. In 2004, LAFCO counted room under the plan for 211 more homes, about 45,000 square feet of commercial space and about 90,000 square feet of industrial space, more than the sewer plant could then serve.
Two connections tie Graton to its neighbors:
- West County Regional Trail: the mostly paved 5.5-mile trail runs through Graton between Sebastopol and Forestville on the bed of the old Petaluma and Santa Rosa Railway. The Graton Road trailhead has accessible parking and 0.7 miles of paved, gentle trail heading north, and a section just north of town is an elevated boardwalk (Sonoma County Regional Parks).
- Route 20: Sonoma County Transit’s daily Route 20 has a Graton timepoint between the Sebastopol hub and downtown Forestville, and it continues to the Santa Rosa Transit Mall and the downtown Santa Rosa SMART station (Route 20 schedule).
Census school-district maps place Graton in the Oak Grove Union School District for elementary and middle grades and the West Sonoma County Union High School District; confirm the assigned schools with the district for a specific address.
Renting, building and hazard checks in Graton
Short-term rentals follow the county’s vacation rental rules: a zoning permit, a certified vacation rental property manager, a license and a transient occupancy tax number, with no rentals in R1, R2 or R3 zoning or in ADUs. The 2023 rezoning table of recommended caps and exclusion zones, which named several other west county neighborhoods, didn’t list Graton (Permit Sonoma). For long-term rentals, the county’s 2024 tenant ordinance gives just-cause protection from the first day of the tenancy; see our guide to vacation rental rules in Sonoma County for the short-term side.
- ADUs: county rules effective January 8, 2026 allow a detached ADU of up to 1,200 square feet on a single-family lot, with no parking required. In Graton, the sewer connection or septic capacity is the first thing to check. Our land and ADU guide explains the permit order.
- Fire: look up the parcel’s Fire Hazard Severity Zone on the State Fire Marshal’s viewer. In a High or Very High zone, AB 38 requires a defensible-space inspection at sale or a written agreement for the buyer to complete one within a year.
- Flood: parcels near Atascadero Creek and its wetland should get a FEMA flood zone check and a flood insurance quote.

How Diamond Real Estate Group helps Graton buyers
In Graton, the questions that decide a purchase are usually utilities and use. We confirm whether the parcel is in the sewer district or on septic, track down the water source and its paperwork, check the zoning before you plan a rental or an ADU, and look up the fire and flood maps. Then we price the home against sales that share its utilities, not just its ZIP code.
For more, see our Sonoma County real estate guide and how we help buyers. If you own in Graton and are thinking of selling, our seller services start with the same utility records.
Selling a home in Graton
Graton is unincorporated, so Permit Sonoma handles its permits, wells and septic, and only the county transfer tax applies. Sewer belongs to the Graton Community Services District, which requires residences in its service area to be connected.
Sewer facts buyers ask for
The district lists an annual treatment rate of $1,574.37, collected on the Sonoma County property tax bill. Buyers comparing Graton with septic homes nearby will add it to their carrying costs, so state it plainly. New hookups are limited by plant capacity and carry an initial fee of $10,352, which matters to any buyer planning an added connection.
The district says owners are responsible for maintaining private laterals. Its website describes no point-of-sale lateral inspection, but call (707) 823-1542 to confirm before you list.
Water, flood and fire
- Water. The county lists no water district for Graton, so document the source: the well log, a flow test, water-quality results and any shared-well agreement. See our rural utilities guide.
- Flood. Near Atascadero Creek, check the FEMA map and ask Permit Sonoma for any elevation certificate it holds or a flood zone determination.
- Fire. If the parcel maps High or Very High, provide AB 38 documentation or sign a buyer agreement; our AB 38 page explains both routes.
- Septic outside the district. A system with supplemental treatment needs its yearly operational permit, and form WLS-043 obliges you to inform the buyer.
Transfer tax and state items
The county charges $0.55 per $500, net of any assumed loan: $1,045 on a $950,000 sale. Custom in Diamond’s North Bay markets puts it on the seller, though the parties can negotiate; see California transfer tax. State law adds a smoke alarm statement, a water heater bracing certification and the noncompliant-fixture disclosure.
For a price that compares sewered Graton homes with each other, start with a home valuation.
