Sonoma CA Real Estate & Homes For Sale
Sonoma is an incorporated city in Sonoma Valley on State Route 12, about 45 miles north of San Francisco, but the 95476 ZIP also covers unincorporated areas under county rules. Inside the city, homes use city water and district sewer, new vacation rentals are barred, and a voter-approved growth boundary holds through 2040.

Sonoma homes for sale include houses near the historic Plaza and properties in the surrounding Sonoma Valley, but a Sonoma mailing address does not settle which jurisdiction governs the property. Start with the homes for sale in Sonoma below, then compare the setting, approved use and ownership costs of each address. Sonoma houses for sale around the city center, Boyes Hot Springs, El Verano and Temelec should not be treated as one interchangeable market.

What do homes in Sonoma sell for right now?
Through August 2026, a typical City of Sonoma sale closed for about $1.05 million after about seven weeks on the market, at roughly 97% of its list price. Countywide prices were lower: the Sonoma County median was $875,000 in September 2026, according to the California Association of REALTORS® (C.A.R.).
| Measure | Figure | Period and source |
|---|---|---|
| Median sale price, City of Sonoma | $1,049,306 | Three months ending August 2026, Redfin |
| Median sale price per square foot | $597 (down 1.2% from a year earlier) | August 2026, Redfin |
| Median days on market | 48 (61 a year earlier) | August 2026, Redfin |
| Sale-to-list price ratio | 97.2% | August 2026, Redfin |
| Homes sold above list price | 13.4% | August 2026, Redfin |
| Homes sold in August | 46 (up 24.7% from August 2025) | August 2026, Redfin |
| Sonoma County median price | $875,000 (up 10.1% from $795,000) | September 2026, C.A.R. |
| Median value of owner-occupied homes, City of Sonoma | $970,500 | 2020-2024, U.S. Census Bureau American Community Survey |
Read the city median with care. Sonoma records only a few dozen sales a month, so a handful of large-property sales can move it. Redfin’s three-month median was 19.3% lower than a year earlier while the median price per square foot fell only 1.2%. That gap points to a change in the mix of homes that sold more than to a broad drop in values. Price per square foot and the sale-to-list ratio are steadier guides when you compare listings.
The Census figure measures something different. It’s the value owners reported in surveys from 2020 to 2024, not what buyers paid this year.
Is a “Sonoma” address inside the City of Sonoma?
Not always. The 95476 ZIP code covers the City of Sonoma and several unincorporated places around it: Boyes Hot Springs, El Verano, Eldridge, Fetters Hot Springs-Agua Caliente and Temelec. Outside the city limits, Sonoma County’s rules apply instead of the city’s, which changes who issues permits, where the water comes from and whether the home can ever be a vacation rental.
| Topic | Inside the City of Sonoma | Unincorporated Sonoma Valley |
|---|---|---|
| Planning and building permits | City of Sonoma Planning Department | Permit Sonoma (County of Sonoma) |
| Water | The city’s own water utility, which bills about 5,000 customers | Depends on the parcel: a water district or a private well |
| Sewer | Sonoma Valley County Sanitation District | The sanitation district where lines exist; otherwise a septic system under county rules |
| New vacation rentals | Prohibited since early 2018, except the adaptive re-use of a historic structure | County permit, certified property manager and license required; not allowed in R1, R2 or R3 zoning or in exclusion and capped areas |
| Transfer tax | County rate only: $1.10 per $1,000 of value | The same county rate |
| Growth limits | Voter-approved urban growth boundary through December 31, 2040 | County General Plan and area plans, such as the Springs Specific Plan |
| Fire hazard map | City-adopted map based on CAL FIRE’s 2025 update | CAL FIRE maps, with Permit Sonoma as the local inspection authority |
Two county plans will shape the housing supply just outside the city. The Springs Specific Plan covers about 178 acres in Agua Caliente, Fetters Hot Springs and Boyes Hot Springs, immediately north of the city, and would allow more than 700 homes along a mixed-use “main street” on Highway 12. When we checked in October 2026, Permit Sonoma still listed it in environmental review. Up the valley, the Specific Plan for the former Sonoma Developmental Center campus in Glen Ellen, approved by the Board of Supervisors in December 2022, sets a base of 620 homes, each capped at 1,800 square feet, and protects 700 acres of open space. The developer, Eldridge Renewal, has since applied for 990 homes (200 of them affordable), a 150-room hotel and about 130,000 square feet of commercial space. The county says the draft environmental report won’t be ready in 2026 (Permit Sonoma).
What kinds of homes are in Sonoma?
The city is small and mostly owner-occupied. The Census Bureau counts about 5,990 housing units and 5,285 households in the city, with 65% of homes occupied by their owners and an average of 1.97 people per household (American Community Survey, 2020-2024). Across the wider 95476 ZIP code, ATTOM’s 2025 property data puts the average single-family home at 1,772 square feet and 54 years old.
Voters, not developers, set the city’s edge. Sonoma’s voters created an urban growth boundary with Measure S in November 2000 and extended it to December 31, 2040, with Measure W in November 2020. Moving the line now takes a public vote, except in limited cases that need a four-fifths City Council vote. With the boundary fixed, new homes inside the city have to fit on land already within it.
Outside the boundary, the valley is farm and wine country. Sonoma Valley has more than 100 wineries and about 13,000 acres of wine grapes, according to the Sonoma Valley Visitors Bureau. Rural listings can combine a house with planted acreage and may rely on a private well and septic system. Our page on luxury homes and estates in Sonoma covers the vineyard and estate end of the market.
What should you check before buying a home in Sonoma?
Check five things before your inspection deadline: the fire hazard zone, the utilities, the zoning and rental rules, insurance, and the property tax you’ll actually pay. Each can change your budget or your plans for the house.
The fire hazard severity zone
CAL FIRE updated its Fire Hazard Severity Zone maps for local responsibility areas, where cities and local fire districts handle wildfire protection, on February 24, 2025. The City of Sonoma prepared its map from that update, and adoption was on the May 7, 2025 City Council agenda. Cities may raise a zone’s rating but not lower it. Homes in High and Very High zones face added building-code requirements, and Very High zones add defensible-space landscaping rules. Look up the address on the city’s fire hazard map before you write an offer.
When a home in a High or Very High zone sells, California’s AB 38 rule (Civil Code §1102.19, in effect since July 1, 2021) requires the seller to give the buyer documentation that the property complies with defensible-space rules, from an inspection in the six months before the sale. If that documentation isn’t ready by closing, buyer and seller sign an agreement that the buyer will bring the property into compliance within one year (Office of the State Fire Marshal). Our guide to wells, septic and rural property covers the other inspections rural buyers order.
Water, sewer and septic
Inside the city, water comes from the City of Sonoma’s utility. The Sonoma Valley County Sanitation District, whose board is Sonoma Water’s Board of Directors, collects and treats wastewater at its plant on Eighth Street East. Outside city limits, ask which agency supplies water or request the well records, and for a septic system, ask for the permit history and an inspection. The valley’s groundwater basin, the Sonoma Valley Subbasin, is rated medium priority under California’s Sustainable Groundwater Management Act. It’s managed by the Sonoma Valley Groundwater Sustainability Agency, formed in 2017. Our guide to wells, septic and rural utilities in Sonoma County explains the inspections.
Zoning, historic homes and rental plans
Older homes near the Plaza can carry extra rules. In the city’s historic overlay zone, demolishing a structure requires a historic resource evaluation by a qualified architectural historian and a Planning Commission hearing (Sonoma Municipal Code §19.54.090). The city’s Historic Preservation Commission also designates local historic resources and districts. If you plan to remodel, add on or rebuild, confirm the parcel’s status with the Planning Department before you remove contingencies.
Rental plans need the same check. The City of Sonoma stopped accepting new vacation rentals in early 2018. Existing licensed rentals can continue, and the only new applications allowed involve the adaptive re-use of a historic structure (City of Sonoma). In practice, a home inside city limits can’t be bought to start a new short-term rental. Long-term rentals are a separate question, covered on our Sonoma investment property page.
Insurance
Get homeowners insurance quotes during your contingency period, not after it. The cost and availability of coverage depend on the home’s fire zone, roof, defensible space and claims history, and a hard-to-insure house can change your budget or your lender’s approval. Ask the seller for the property’s insurance claims history.
Property taxes, loan size and closing costs
California’s Proposition 13 caps the base property tax rate at 1% of assessed value, plus voter-approved bonded debt, and limits increases in assessed value to 2% a year. A purchase resets the assessed value to current market value, usually the price you pay, so your bill will be based on your price, not the seller’s (State Board of Equalization). Ask for the seller’s latest tax bill to see the parcel’s special assessments.
Loan size matters at Sonoma prices. For 2026, the Federal Housing Finance Agency set the conforming loan limit for one-unit homes at $832,750 in most of the country and up to $1,249,125 in the highest-cost areas. A loan above your county’s limit is a jumbo loan, with its own down-payment and reserve rules, so check Sonoma County’s figure on FHFA’s county list with your lender.
At closing, Sonoma County’s documentary transfer tax is $1.10 per $1,000 of value, and the City of Sonoma adds none of its own. Santa Rosa and Petaluma each add $2.00 per $1,000 (Sonoma County Clerk-Recorder). Our guide to buying a home in Sonoma County walks through the other closing costs.
Inspections worth ordering
Beyond the general home inspection, plan on specialists where the property calls for them: sewer lateral, roof, chimney, drainage, pest and pool, plus well and septic on rural parcels. Hillside and older homes may justify a geotechnical review. Price per square foot is only one data point, because lot quality, views, condition, systems and outbuildings can matter more, and unusual properties carry more appraisal risk. Don’t shorten a contingency until the people who need to inspect the home have had time to do the work.
How do you get around from Sonoma?
Plan on driving for most trips. Sonoma sits on State Route 12, about 45 miles north of San Francisco by the Sonoma Valley Visitors Bureau’s measure. The Census Bureau puts the average commute for city residents at 25.4 minutes (2020-2024).
- Bus: Sonoma County Transit Route 30 runs from Sonoma Plaza through El Verano, Boyes Hot Springs, Glen Ellen, Kenwood and Oakmont to Santa Rosa, with eight or nine trips each way a day. The full run to Coddingtown takes about an hour and a half.
- Rail: SMART commuter trains don’t stop in Sonoma Valley. Their Sonoma County stations are in Petaluma (Downtown Petaluma, and Petaluma North at 320 Corona Road, which opened in January 2025), Cotati, Rohnert Park, Santa Rosa, Windsor and at the county airport (Sonoma County Tourism).
- Bay Area trips: drive times to San Francisco, the East Bay and the airports swing widely with traffic. Test the drive at the hours you’d travel before you commit.
Daily life in Sonoma: the Plaza, parks, schools and health care
Town life centers on Sonoma Plaza, an eight-acre square that General Mariano Vallejo laid out in 1835, dedicated as a National Historic Landmark in 1961. City Hall, dedicated in 1908, stands at its center with four identical facades. The Bear Flag was raised here on June 14, 1846, and the seasonal Tuesday night farmers market is held on the Plaza.
The sites of Sonoma State Historic Park are steps from the Plaza. They are Mission San Francisco Solano, founded July 4, 1823, the northernmost of California’s Franciscan missions; the Sonoma Barracks on East Spain Street; and General Vallejo’s home on Third Street West.
- Trails: the Sonoma Overlook Trail starts on First Street West at the entrance to Mountain Cemetery. It’s about 2.4 miles round trip with roughly 400 feet of climbing; dogs, bikes and horses aren’t allowed.
- Parks: Maxwell Farms Regional Park on Verano Avenue has playing fields, courts, playgrounds and 2.5 miles of trails with access to Sonoma Creek. Sonoma Valley Regional Park, next to Glen Ellen, adds the paved Valley of the Moon Trail and a fenced off-leash dog park.
- Schools: public schools are run by the Sonoma Valley Unified School District. Confirm the school assignment for a specific address with the district.
- Health care: Sonoma Valley Hospital, at 347 Andrieux Street since 1957, has a 24-hour emergency department and an affiliation with UCSF.
The valley around the city is wine country. The Sonoma Valley American Viticultural Area was federally established in 1981, and the valley’s first vineyards were planted by the mission fathers in 1824. The often-quoted “more than 425 wineries” is the figure for all of Sonoma County, not Sonoma Valley.
How does Sonoma compare with nearby areas?
If Sonoma is on your list, these neighbors are worth a look. The biggest differences are local government, transit and transfer tax, not just price.
| Area | What it is | Worth knowing |
|---|---|---|
| Sonoma | Incorporated city in Sonoma Valley | Growth boundary to 2040; no new vacation rentals; county transfer tax only |
| Glen Ellen | Unincorporated community up the valley | County rules; Route 30 stops at Arnold Drive and London Ranch Road; home to the Sonoma Developmental Center plan |
| Kenwood | Unincorporated community farther up Highway 12 | County rules; Route 30 stops at Highway 12 and Greene Street |
| Petaluma | Incorporated city in southern Sonoma County | SMART rail service; city transfer tax of $2.00 per $1,000 on top of the county’s |
| Santa Rosa | Incorporated city at Route 30’s other end | SMART rail service; city transfer tax of $2.00 per $1,000 on top of the county’s |
| Napa | Incorporated city in neighboring Napa County | Napa County’s September 2026 median was $918,000 (C.A.R.); different county rules and taxes |
How Diamond Real Estate Group helps Sonoma buyers
Start with the questions that decide whether a property works for you: which side of the city limit it’s on, what the fire map and zoning allow, how it gets water and sewer, and what it will cost to insure and own. Then compare the property with recent sales so your offer reflects both the house and its risks.
If your plans go beyond buying a home to live in, these pages go deeper:
- Selling a home in Sonoma: pricing, timing and local selling costs.
- Investment property in Sonoma: long-term rental rules and the numbers.
- Licensed agents serving Sonoma: a disclosed list with each DRE license linked.
- Luxury homes and estates in Sonoma: the top of the market, including vineyard estates.
For the rest of the county, start with our Sonoma County real estate guide. For the steps of buying anywhere we work, see how we help buyers.
Luxury, rural and estate properties in Sonoma
Sonoma’s estate, acreage and vineyard homes follow different rules depending on one question: is the parcel inside the City of Sonoma or in unincorporated Sonoma Valley? Inside the city, homes use the city’s water utility and the Sonoma Valley County Sanitation District’s sewer (City of Sonoma; Sonoma Water), and the voter-approved urban growth boundary framework extends through 2040, with the amendment procedures and exceptions in the adopted ordinance (City of Sonoma). Most acreage sits outside that line, where Permit Sonoma permits septic systems and the county’s well ordinance governs private wells. On an estate or vineyard parcel, ask early for the well log, any pump or yield test and the septic permit and its capacity, because water supply, wastewater capacity and permit conditions affect what improvements are feasible.
Two more county items shape rural value. Some farm parcels carry a Williamson Act contract, which lowers the assessment in exchange for limits on use. And outside the cities, Permit Sonoma applies administrative design review to homes inside designated Scenic Resources, covering building and driveway location, materials, colors and lighting. Check both on the county parcel search before you plan a guest house or rebuild.
Insurance is the other early step. The California FAIR Plan’s residential limit is $3 million per location (Department of Insurance), so compare that with a rebuild estimate; see our FAIR Plan guide and insuring a high-value home. Compare policy limits and covered perils with a current rebuild estimate through a licensed insurance professional. FAIR Plan dwelling coverage is limited named-peril coverage; additional Difference in Conditions, flood or earthquake coverage may be needed.
For the valley’s higher-end homes, see Sonoma luxury homes and estates, Sonoma County luxury homes, Sonoma County vineyards for sale, Armstrong Estates, and the valley towns of Glen Ellen and Kenwood.
Private and coming-soon listings
Some Sonoma owners prefer a quiet sale. Ask Diamond Real Estate Group which permitted private-marketing options fit your property, goals and the applicable MLS rules. Availability of any particular listing is not guaranteed. We can’t promise that a particular private listing will be available to any buyer.
For listings covered by the applicable MLS’s Clear Cooperation rules, public marketing generally triggers submission to the MLS within one business day. NAR’s Multiple Listing Options for Sellers policy distinguishes an office-exclusive listing from a delayed-marketing listing: a delayed listing is still filed with the MLS and available to its participants while public IDX and syndication distribution is delayed. Seller certification and informed consent are required, and the local MLS sets its submission, coming-soon and delay rules. Ask the listing broker which rules apply before choosing a marketing plan. See NAR Clear Cooperation and Multiple Listing Options for Sellers. For practical questions, read our guides to pocket listings in California and coming-soon listings in the Bay Area.
Permits, ADUs and remodels in Sonoma
Who issues the permit depends on the city line. Inside the City of Sonoma, the city’s Planning Department and Building Division handle zoning, design and building permits. In the historic overlay zone, demolition needs a demolition permit before any building permit, the Planning Commission decides it after a public hearing, and the Commission may require design review of the replacement building (Sonoma Municipal Code §19.54.090). Outside the city, including Boyes Hot Springs, El Verano, Glen Ellen and Kenwood, Permit Sonoma issues permits, including for accessory and junior accessory units.
State law limits how far a city or county can restrict ADUs; the state housing department’s ADU page and handbook explain the rules. Two local points matter when you buy a home with a second unit: confirm it was permitted and finaled, and check the city’s restrictions on new vacation rentals rather than assuming a second unit can be operated as short-term lodging (City of Sonoma), so plan the unit for family or long-term use. On a rural parcel, an ADU also needs septic capacity and a confirmed water supply.
Sonoma real estate: questions people ask
Who is a Sonoma, CA realtor who covers both the city and the valley?
Diamond Real Estate Group’s broker, Matthew Martinez (California DRE #01869679), works with buyers and sellers in the City of Sonoma and in unincorporated Sonoma Valley, including Glen Ellen, Kenwood and the Springs. Because those areas follow different permit, water and rental rules, we start every search by confirming which jurisdiction governs each address.
How do I search all of Sonoma Valley, not just the city?
Start with the listings on this page, then widen the search to Glen Ellen, Kenwood and the Springs. Outside city limits, check the county’s vacation rental rules and the parcel’s well and septic records before you compare prices.

Selling a home in Sonoma
Homes inside the City of Sonoma are city permit files; the Springs, Glen Ellen and the rest of the valley outside city limits are Permit Sonoma’s. For older houses near the Plaza, collect the permits and finals for every remodel before listing. Our article on historic homes near the Plaza describes what buyers look for in them.
Transfer tax
The City of Sonoma has no transfer tax of its own; the county recorder includes it in the county’s $1.10 per $1,000. A $1,050,000 sale pays $1,155. Sellers customarily pay in Diamond’s North Bay markets, though it is negotiable. See our transfer tax guide.
The sewer lateral question
The Sonoma Valley County Sanitation District, which takes in the city, has a private sewer lateral ordinance. It requires owners of property 30 years or older to have their laterals inspected and repaired if necessary. The district offers free video inspections. A rating of 1 to 3 earns a letter of compliance; a 4 or 5 is failing, and the owner has one year to repair. The trigger is the lateral’s age, not a sale, but buyers will ask where the home stands. Have the district’s report or letter in the disclosure package. The Sonoma Index-Tribune reported a county loan of up to $10,000 for the work, repaid over ten years on the tax bill.
Fire zone and state items
- Defensible space. In a High or Very High zone, Civil Code 1102.19 requires documentation or a signed buyer agreement. Sonoma Valley Fire District schedules inspections online for parcels in its service area; check its map first, since it charges a $66 refund fee for parcels outside it.
- Smoke alarm and water heater. A written smoke alarm compliance statement and a written bracing certification.
- Plumbing fixtures. The Civil Code 1101.4 disclosure on noncompliant fixtures.
Our full guide to selling a home in Sonoma covers pricing and timing. To see what your home might sell for, ask for a Sonoma home valuation.

Sonoma home buying FAQs
Can I buy a home in the City of Sonoma and use it as a vacation rental?
Not as a new vacation rental. The city has prohibited new vacation rentals since early 2018. Existing licensed rentals can continue, and new applications are limited to the adaptive re-use of a historic structure. Outside city limits, Permit Sonoma requires a permit, a certified property manager and a license, and doesn’t allow vacation rentals in R1, R2 or R3 zoning.
What transfer tax applies when I buy in Sonoma?
Sonoma County’s documentary transfer tax: $1.10 per $1,000 of value, charged as $0.55 per $500. The City of Sonoma doesn’t add its own, while Santa Rosa and Petaluma each add $2.00 per $1,000.
Can the city grow into the surrounding countryside?
Not without a vote. Sonoma’s urban growth boundary was created by Measure S in 2000 and extended through December 31, 2040, by Measure W, approved on November 3, 2020. Future changes need voter approval, except in limited cases that require a four-fifths City Council vote.
How far is Sonoma from San Francisco?
About 45 miles, by the Sonoma Valley Visitors Bureau’s measure. Drive time depends heavily on traffic, so try the route at the hours you’d travel.
Do I need special inspections for a Sonoma home?
Often. Older homes call for sewer lateral, roof, chimney and drainage inspections, and rural properties need well and septic inspections. In High and Very High fire hazard zones, the seller also owes you defensible-space documentation under AB 38.
Are Sonoma home prices falling?
Not clearly. Redfin’s three-month median through August 2026 was 19.3% lower than a year earlier, but price per square foot fell only 1.2%, and the Sonoma County median for September 2026 was up 10.1% (C.A.R.). In a market this small, the mix of homes sold moves the median.
Can I buy a fractional share of a home in Sonoma?
The City of Sonoma has moved against it: on January 19, 2022, the City Council unanimously adopted an urgency ordinance prohibiting timeshare and fractional interest uses, and their advertising, citywide, and staff said a regular ordinance would follow (City of Sonoma). Outside city limits, the county has treated short-term use of a fractionally owned home as timeshare use since April 2023, allowed only in the recreation and visitor-serving (K) zone (Permit Sonoma). Ask the Planning Department about the current rule for a specific property, and see our guide to Pacaso and co-ownership.
Can I buy in Sonoma with less than 20% down?
Often, depending on the loan program, your qualifications and the property. First-time buyers who will live in the home and meet income limits may qualify for CalHFA’s MyHome Assistance, a deferred-payment junior loan of up to 3.5% of the price with an FHA loan or 3% with a conventional one. At Sonoma prices, check early whether your loan will be conforming or jumbo; our first-time buyer’s guide to Sonoma covers the steps.
Do older Sonoma homes come with a lead-paint disclosure?
Yes, if the home was built before 1978. The seller must give you the EPA’s lead pamphlet, a Lead Warning Statement, any known information about lead-based paint and the available reports, and you get 10 days for a lead inspection unless you agree in writing to change or waive that period (EPA). With the average single-family home in ZIP 95476 at 54 years old (ATTOM, 2025), the rule comes up often here.
What should I get from the HOA when buying a Sonoma condo or townhome?
Under Civil Code §4525, the seller provides the governing documents, a statement of current regular and special assessments and anything unpaid, approved assessment changes not yet due, any rental restrictions, the latest inspection report under Civil Code §5551 and, on request, 12 months of approved board minutes. Inside city limits, the ban on new vacation rentals applies whatever the HOA’s own rules say.
Is new housing being built in or near Sonoma?
Some, within tight limits. The city’s share of the Bay Area’s 2023-2031 housing need is 311 homes, allocated by the Association of Bay Area Governments in December 2021 (Sonoma Index-Tribune), and with the growth boundary fixed through 2040 they have to fit inside the current city. The larger numbers are just outside it: room for more than 700 homes in the Springs Specific Plan and a base of 620 in the Sonoma Developmental Center plan.
Can I buy a rural or vineyard property near Sonoma?
Yes, outside the growth boundary, where county rules apply. Some farm parcels are under Williamson Act contracts, which run 10 years and renew automatically, trading a lower property assessment for limits on how the land is used (Permit Sonoma), and the county doesn’t allow vacation rentals on contract land. Ask whether the parcel is under contract and get the well and septic records early; our page on Sonoma estates and vineyard homes covers the top of that market.
