Solano County Cities Compared: A Relocation Guide to Fairfield, Vacaville, Vallejo, Benicia, Suisun City, Dixon & Rio Vista

If you're looking at Solano County, you've probably already noticed it doesn't behave like one market. Fairfield isn't Vacaville. Vallejo isn't Benicia. Rio Vista barely resembles any of them. Solano County sits in Northern California between the Bay Area and the Sacramento region, and its seven cities — Fairfield, Suisun City, Vacaville, Vallejo, Benicia, Dixon and Rio Vista — each grew up around different geography, different industries and different transportation routes. That's why "moving to Solano County" isn't really one decision. It's seven smaller decisions wearing one trench coat.

This guide walks through each city on the same basic terms: where it sits, what the housing stock looks like, how people actually get around, and what the downtown or waterfront experience is like. Nothing here ranks one city above another — what fits a two-hour BART-adjacent commute, a work-from-home budget upgrade, or a slower Delta pace is a personal calculation, not a scoreboard. Read through the differences and decide for yourself which one lines up with how you actually live.

A quick note on the numbers: housing figures below come from Redfin's median sale price data (all home types), which tracks what actually closed, not asking prices. Because Redfin refreshes each city's page on a rolling basis, the reporting months vary slightly by city — each figure is dated so you can compare accurately rather than assume a single snapshot in time.

Where Solano County Sits

Solano County occupies the geographic hinge between the Bay Area and the Sacramento Valley. Interstate 80 runs through the county's spine, connecting Vallejo, Fairfield, Suisun City, Vacaville and Dixon on its way from the Bay Bridge toward Sacramento. Interstate 680 and Interstate 780 branch south through Benicia toward Concord and the East Bay via the Benicia-Martinez Bridge, and Interstate 505 splits off from I-80 near Vacaville toward Winters and I-5. State Route 12 connects Fairfield and Suisun City eastward to Rio Vista and the Sacramento River Delta. That highway geometry, more than anything else, explains why each city has a different relationship to commuting, weekend errands, and what "close to the freeway" even means.

Fairfield

Fairfield is the Solano County seat and sits roughly in the geographic middle of the county, straddling I-80 with Suisun City immediately to its southeast. It's the largest city in the county by population and functions as its commercial and government hub — the Solano County Government Center, Solano Community College's main campus, and Travis Air Force Base (which anchors the city's eastern side) are all here.

Housing: Fairfield's housing stock spans decades of development, from older neighborhoods near downtown to newer subdivisions on the city's west side near Green Valley and the Rancho Solano golf community, plus larger-lot development around Cordelia at the I-80/I-680 interchange. Redfin put Fairfield's citywide median sale price at $622,911 in June 2026, up 6.5% year-over-year. Prices vary noticeably by side of town — the west-side 94534 ZIP code, with newer and larger homes, has traded at a premium to the city's east and central neighborhoods.

Getting around: Fairfield sits at the intersection of I-80 and I-680, and the Suisun-Fairfield Amtrak Capitol Corridor station (shared with Suisun City) offers train service toward Sacramento and the East Bay/San Jose corridor. Fairfield and Suisun Transit (FAST) runs local buses, and SolTrans express routes connect Fairfield to Vallejo and BART's El Cerrito del Norte station.

Amenities: Downtown Fairfield is compact and government-centered, while the Fairfield-Suisun waterfront district (shared with neighboring Suisun City) has seen redevelopment investment. Solano Town Center is the county's main enclosed mall, and Jelly Belly's factory and visitor center is one of the county's most-visited attractions. Fairfield is also a short drive from the Suisun Valley wine region, a lower-key alternative to Napa proper. If wine country proximity without Napa pricing is part of your search, "Love Napa Wine Country but Not Napa Home Prices? Meet Suisun Valley" digs into that in more detail.

Suisun City

Suisun City is Solano County's smallest city by land area and sits directly against Fairfield's southeastern edge — the two are functionally contiguous, sharing a school district and much of their commercial corridor. What sets Suisun City apart geographically is its waterfront: the city was built around Suisun Slough, a tidal channel that connects to the Sacramento River Delta, and its historic Main Street and marina sit right on the water.

Housing: Suisun City's housing stock leans toward smaller, more affordable single-family homes and townhomes relative to its Fairfield neighbor, with less new construction in recent years. Redfin reported a median sale price of $529,500 in March 2026, down 6.9% year-over-year.

Getting around: The Suisun-Fairfield Capitol Corridor station is technically inside Suisun City limits, at the head of Main Street, making it one of the more walkable train stations in the county from a downtown core. FAST buses and SolTrans regional routes also serve the city.

Amenities: The Suisun City waterfront and marina, with its promenade and seasonal events, is the city's defining feature — a small-town harbor feel that's uncommon elsewhere in the county. Downtown Main Street is walkable and historic in scale. For buyers comparing these two neighboring cities directly, or weighing a first home purchase on a single income, "Buying Your First Home Solo? Why Fairfield and Suisun City Deserve a Look" covers that comparison directly.

Vacaville

Vacaville sits north of Fairfield along I-80, roughly halfway between the Bay Area and Sacramento, and is the county's second-largest city. It has grown substantially over the past few decades, with newer residential development extending north and east of the historic downtown core, and Interstate 505 splitting off here toward Winters, Davis and I-5 — a route many residents use to reach Sacramento or UC Davis.

Housing: Vacaville's housing stock mixes an older historic downtown core with large tracts of newer single-family subdivisions built from the 1990s onward. Redfin reported a citywide median sale price of $626,625 in May 2026, up 1.2% year-over-year, with the 95687 ZIP (generally the newer, eastern side) and 95688 ZIP (older, western side) trading at different price points within the city.

Getting around: Vacaville sits along I-80 and near the I-505 split, and the Fairfield-Vacaville Capitol Corridor station — despite its name, located closer to Vacaville along Vanden Road — provides train access toward Sacramento and the East Bay. Vacaville City Coach runs local bus routes.

Amenities: Historic Downtown Vacaville retains its early-20th-century storefronts and hosts a regular farmers market, while the Nut Tree area and Vacaville Premium Outlets serve as the city's larger retail and dining hubs. Vacaville is also a common jumping-off point for Lake Berryessa via State Route 128, and for Napa Valley via the same route.

Vallejo

Vallejo sits at the county's southern edge on the Carquinez Strait, where the strait opens into San Pablo Bay. It's the only Solano County city with direct ferry access to San Francisco, and its history as a former Mare Island Naval Shipyard town shapes both its waterfront geography and its housing stock — Vallejo briefly served as California's state capital for a matter of months in the early 1850s before the capital moved on to Benicia and then Sacramento.

Housing: Vallejo has the county's most varied housing stock, ranging from Victorian-era homes in the historic core to hillside neighborhoods with bay views to more recent subdivisions on the city's outskirts. Redfin data has put Vallejo's citywide median sale price around $511,000 as of March 2026, with individual ZIP codes and neighborhoods varying widely around that citywide figure.

Getting around: Vallejo is Solano County's ferry city — the San Francisco Bay Ferry runs daily service between the Vallejo Ferry Terminal and downtown San Francisco, a roughly one-hour crossing. The Vallejo Transit Center, next to the ferry terminal, is SolTrans' hub, with routes connecting to BART's El Cerrito del Norte station and to Napa via VINE Transit. Vallejo is also served by I-80 and State Route 37 toward Marin and Sonoma.

Amenities: Downtown Vallejo has a walkable waterfront core built around the ferry terminal, and Six Flags Discovery Kingdom sits on the city's north side. Mare Island, the former naval shipyard, has its own distinct historic housing stock and waterfront trails.

Benicia

Benicia sits directly across the Carquinez Strait from Martinez, connected by the Benicia-Martinez Bridge on I-680/I-780. Like Vallejo, it briefly served as California's state capital — from 1853 to 1854 — before the capital relocated to Sacramento, and its well-preserved downtown reflects that 19th-century history.

Housing: Benicia's housing stock is generally older and more established than the county's newer-growth cities, concentrated around a compact city footprint with limited room for new large-scale subdivisions. That relative scarcity shows up in price: the 94510 ZIP code (which covers nearly all of Benicia) had a Redfin median sale price of $812,000 in March 2026, up 3.8% year-over-year — among the higher figures in the county.

Getting around: Benicia's main access is I-680/I-780 across the Benicia-Martinez Bridge, connecting to the East Bay and the wider Bay Area freeway network. SolTrans runs local and express bus routes through Benicia, including connections to the Vallejo ferry and BART.

Amenities: Benicia's downtown First Street is one of the more walkable, boutique-lined main streets in the county, running down toward a small marina on the strait. The city also has a working industrial waterfront (including a refinery) alongside its historic and arts-oriented downtown — a geography that's part of what distinguishes Benicia's layout from Vallejo's.

Dixon

Dixon is the county's northernmost city, sitting along I-80 near the Yolo County line — closer, in practice, to Davis and Sacramento than to the Bay Area side of the county. It retains a strong agricultural identity, surrounded by farmland rather than the bay or delta geography that shapes the county's other cities.

Housing: Dixon's housing stock is smaller in overall inventory than the county's larger cities, with a historic core surrounded by more recent residential development. Redfin reported a median sale price of $589,647 in May 2026, down 9.6% year-over-year — figures that can move more per month than larger cities simply because fewer homes sell there in any given period.

Getting around: Dixon sits directly on I-80, making it a straightforward drive toward Sacramento or the East Bay, though it does not have its own Capitol Corridor station — the nearest train service is at the Suisun-Fairfield station to the south or in Davis to the northeast.

Amenities: Dixon's small downtown centers on agricultural and small-town identity, and the city hosts the Dixon May Fair, a longtime regional event. Its proximity to UC Davis (a short drive up I-80) is a draw for people connected to the university without wanting to live inside Davis itself.

Rio Vista

Rio Vista is Solano County's most geographically distinct city — set on the Sacramento River in the Sacramento-San Joaquin Delta, reached primarily via State Route 12, well off the I-80 corridor that connects the rest of the county. It's also the smallest and most rural in feel of the seven cities.

Housing: Rio Vista's housing stock includes an older river-town core plus several age-restricted and master-planned communities (such as Trilogy and Four Seasons) built in recent decades, which make up a significant share of the city's more recent sales. Redfin reported a median sale price of $437,000 over the three months ending May 2026, down 2.9% year-over-year — using a trailing three-month window here rather than a single month, since Rio Vista's lower sales volume makes single-month figures more volatile.

Getting around: Rio Vista is not served by rail, and its main road connection is State Route 12, crossing the Sacramento River via the Helen Madere Memorial Bridge. The Rio Vista Delta Breeze provides local and limited regional bus service, including a route connecting to the Suisun-Fairfield Amtrak station. Commute distances and drive times to Fairfield, the East Bay, or Sacramento are meaningfully longer here than from the county's I-80 cities — plan around actual drive times rather than straight-line distance.

Amenities: Rio Vista's identity is built around the water — marinas, houseboats, and Delta boating and fishing culture, including the city's long-running Bass Derby. Its downtown is small and river-facing, a genuinely different pace than anywhere else on this list.

Comparing Access Across the County

A few patterns are worth keeping in mind as you compare cities:

• I-80 corridor cities — Vallejo, Fairfield, Suisun City, Vacaville and Dixon — sit on or near the county's main east-west freeway and, apart from Dixon, have direct access to Capitol Corridor train service.
• I-680/I-780 corridor — Benicia connects south to the East Bay via the Benicia-Martinez Bridge rather than through the I-80 spine.
• Ferry access — Vallejo is the only city with direct ferry service to downtown San Francisco.
• Delta geography — Rio Vista sits apart from the freeway network entirely, reached via State Route 12, with the longest typical drive times to the rest of the county and the Bay Area.

What's the difference between Fairfield and Suisun City?
Fairfield is the larger of the two and serves as the county seat, with a broader mix of housing stock, retail and government offices. Suisun City is smaller, borders Fairfield directly, and is built around a waterfront marina and historic Main Street. They share a train station and, largely, a school district.

What's the difference between Fairfield and Vacaville?
Both sit along I-80 in central Solano County with a mix of older and newer housing, but Vacaville is farther north, closer to I-505 and Sacramento-area routes, while Fairfield is more central in the county and home to the county government complex and Travis Air Force Base.

Which Solano County city has ferry access to San Francisco?
Vallejo. The San Francisco Bay Ferry runs daily service between the Vallejo Ferry Terminal and downtown San Francisco.

Which Solano County city is closest to wine country?
Fairfield and Suisun City sit closest to the Suisun Valley wine region, a smaller AVA near Napa County. Vacaville is also a common route toward Napa Valley via State Route 128.

Is Rio Vista a good commute to the Bay Area?
Rio Vista is the most distant of the seven cities from the Bay Area's main freeway network, reached via State Route 12 rather than I-80 or I-680. Anyone considering a regular Bay Area commute from Rio Vista should look at actual drive times for their specific route rather than assume it's comparable to the county's I-80 cities.

Do all Solano County cities have train service?
No. Fairfield, Suisun City and Vacaville are served by Capitol Corridor Amtrak stations. Vallejo has ferry service instead of rail. Benicia, Dixon and Rio Vista have no direct rail service, relying on regional bus connections or driving to a neighboring city's station.

A Few Things to Sort Out Next

Every one of these seven cities solves a different set of priorities — freeway access, waterfront living, small-town pace, or proximity to a specific job center. The next useful step is usually pairing this geography with your actual budget: what a given price range buys in Vacaville versus Rio Vista, or what down payment a Suisun City starter home actually requires versus a Benicia hillside property.
