Where to Live in Solano County: Towns Compared by Jurisdiction, Transit and Local Rules

By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.

The quickest way to narrow where to live in Solano County is to decide how you will travel and which set of rules you want on the parcel. Vallejo has a daily ferry to downtown San Francisco, Suisun City and Fairfield have the county’s two Capitol Corridor train stations, and homes outside city limits fall under Solano County planning, where any rental of 30 days or less needs a county permit, a business license and a transient occupancy tax certificate. Then check two parcel-level items that matter more here than in most counties: the Travis Air Force Base land-use compatibility plan, and any special tax or assessment district on a newer subdivision.

This guide compares places only by things you can confirm for a specific address: housing types, jurisdiction, transportation, local rules and ownership costs. It does not describe residents, safety or schools, and it gives no prices or market statistics. For listings, start with our Solano County homes page or search Solano County homes for sale.

Step one: city or unincorporated?

Most Solano County homes sit inside one of its cities: Vallejo real estate, Benicia real estate, Fairfield real estate, Suisun City real estate, Vacaville real estate, Dixon real estate and Rio Vista real estate. Inside city limits, the city’s planning, building and rental rules apply, and water and sewer usually come from a city utility or a public district.

Outside those limits, the County of Solano is the land-use authority. That includes rural communities such as Elmira real estate and much of the farm and ranch land between the cities. Green Valley homes for sale need a parcel-by-parcel check, because the name covers both city and county addresses near Fairfield. A mailing address or ZIP code does not settle the question; confirm jurisdiction with the county or city planning department before you rely on any rule below.

If you are weighing an in-town lot against acreage, our rural house infrastructure guide lists the well, septic, road and utility records to request for county parcels.

Town-by-town comparison

The table summarizes the differences we could confirm. "Check" items are parcel-level questions to answer before you write an offer.

Sources for each column are in the sections below. Highway notes are general orientation; confirm your own route.

Transportation: ferry, Capitol Corridor and highways

Solano has two public transit options that reach beyond the county: a commuter ferry and an intercity train.

• Ferry. The San Francisco Bay Ferry’s Vallejo route runs daily between Mare Island, Vallejo and the Downtown San Francisco terminal. The operator lists about 15 minutes between Mare Island and Vallejo and about 60 minutes from Vallejo to downtown San Francisco. Holiday schedules can differ, so check the current timetable.
• Train. Capitol Corridor serves two Solano County stations, Suisun-Fairfield and Fairfield-Vacaville Hannigan, on a line the operator describes as running between San Jose and Placer County. That gives Fairfield, Suisun City and Vacaville a rail option toward Sacramento and the East Bay. Our post on Hannigan station parking covers the Fairfield-Vacaville station.
• Highways. I-80 is the main corridor through Vallejo, Fairfield, Vacaville and Dixon; I-680 and I-780 serve Benicia; SR 12 links Fairfield and Suisun City with Rio Vista and the Delta; SR 37 runs west from Vallejo toward Marin and Sonoma.

Benicia, Dixon and Rio Vista have neither a ferry terminal nor a train station, so a home there is a car-first choice.

Travis Air Force Base and airport land-use plans

Travis Air Force Base sits east of Fairfield and Suisun City, and its flight operations shape what can be built nearby. The Solano County Airport Land Use Commission lists the Travis Air Force Base Plan as one of three airport land use compatibility plans it administers, and it has a Travis-Rio Vista subcommittee with designated liaisons to the base.

For a buyer, the plan matters in two ways. First, it can limit new construction, added units or certain uses on land in its zones, which matters if you plan an ADU, a lot split or a change of use. Second, it can bring airport-related disclosures into the sale. Read the natural hazard and airport disclosure reports in your escrow package, and for a property near the base, ask the Commission’s staff (Planning Services, 707-784-6765) which plan zone applies before you finalize plans for the property.

Short-term and vacation rental rules

In unincorporated Solano County, the county’s short-term rental page defines a short-term rental as a stay of 30 consecutive calendar days or less, with partial days counted as full days. Before you list, the county says you must:

1. apply for the appropriate permit;
2. obtain a business license; and
3. register for a transient occupancy tax (TOT) certificate.

The county separates rentals of dwellings occupied by a resident family from rentals of dwellings that are not, and the requirements can differ between the two. An occasional home exchange of an owner’s primary residence is excluded. The page does not list which zones allow each type, so confirm the parcel’s zoning with Planning Services before you count on rental income.

Inside a city, the city’s code governs instead. We did not verify each city’s short-term rental rules against a current official page for this guide; check with the city’s planning department.

Farmland and the Williamson Act

Much of the land around Dixon, Vacaville, Elmira and the Delta is farmland, and a farm parcel may be enrolled in a Williamson Act (agricultural preserve) contract that limits how the land can be used and affects how it is assessed. Before you buy acreage, ask the seller and the County Assessor whether a contract is recorded on the parcel and whether a notice of nonrenewal has been filed. Our Williamson Act guide explains how contracts work, and our Solano County vineyard page covers farm and vineyard parcels.

Ownership costs that differ by town

Special taxes in newer subdivisions. Newer planned communities in several Solano cities were financed with community facilities district (Mello-Roos) special taxes or assessment districts, and older neighborhoods often carry none. These charges appear as separate lines on the property tax bill. Ask for the most recent bill and any special tax notice, and compare the bills of two similar homes line by line; our association and assessment analysis and Mello-Roos guide explain what to look for. Plan as well for a supplemental tax bill after closing.

Transfer tax. The Solano County Recorder lists the documentary transfer tax among the special fees collected at recording but does not publish the rate on that page. Confirm the county rate and whether any city tax applies with the Recorder (707-784-6290) or your escrow officer. Who pays is negotiable; see California transfer tax.

Fire insurance. If standard carriers decline a home, the California Department of Insurance describes the California FAIR Plan as a fallback for owners who cannot find coverage in the regular market. Its base coverage is a limited fire policy, so owners typically add a separate difference-in-conditions policy for perils such as water damage, liability and theft. CDI lists a residential limit of $3 million per location; check the current figure. Start quotes early in escrow; see our guides to fire hazard severity zones and insurance during escrow.

Flood and waterfront records. Shoreline, marsh-edge and Delta parcels deserve a records check before you commit. Our waterway and flood records guide and Rio Vista levee and insurance records page list what to request.

How to use this comparison

1. Decide whether the ferry, the Capitol Corridor or I-80 driving matters most for your routine.
2. Decide whether you want a city lot or county acreage with a well and septic.
3. For any parcel near Travis AFB, ask which compatibility zone applies before planning additions.
4. Pull the current tax bill to see special tax and assessment lines.
5. If you may rent short term, confirm zoning and permit type first.

When you have a short list, use our ownership responsibility checklist, start on our buyer page, or contact us to pull parcel records.

Questions people ask

Which Solano County towns have a train station?

Fairfield and Suisun City. Capitol Corridor serves the Suisun-Fairfield and Fairfield-Vacaville Hannigan stations, on a line running between San Jose and Placer County. Vacaville is close to the Hannigan station.

Is there a ferry from Solano County to San Francisco?

Yes. The San Francisco Bay Ferry runs daily between Mare Island, Vallejo and the Downtown San Francisco terminal, about 60 minutes from Vallejo, per the operator. Check current schedules.

Can I rent my Solano County home short term?

In unincorporated areas, a stay of 30 days or less needs a county permit, a business license and a TOT certificate. Inside a city, the city’s code applies; check with its planning department.

Does Travis Air Force Base affect homes nearby?

It can. The Solano County Airport Land Use Commission administers a Travis AFB compatibility plan that can limit new construction and uses near the base. Ask which zone applies and read the airport disclosures.

Why do two similar Solano homes have different tax bills?

Newer subdivisions often carry Mello-Roos special taxes or assessment district charges that older neighborhoods do not, on top of the base property tax. Compare the actual bills line by line.

Does the FAIR Plan cover everything a homeowner policy does?

No. CDI says its base coverage is a limited fire policy; water damage, liability and theft need a separate difference-in-conditions policy.

Is Green Valley in Fairfield?

Partly. The name covers both city and unincorporated county addresses, so check the specific parcel’s jurisdiction before relying on city or county rules.

Notes: The Recorder’s page does not state the documentary transfer tax rate, and we did not confirm whether any Solano city levies its own transfer tax; ask the Recorder or escrow. City short-term rental rules, Travis AFB plan zone maps, Williamson Act enrollment and individual community facilities districts were not verified for this guide; confirm each for the specific parcel. Highway and housing notes are general orientation. Rules change; verify before you buy.
