You’re driving across the Tower Bridge, that iconic gold structure that looks like something out of a steampunk movie. Behind you is the California State Capitol and the glass towers of downtown. Ahead of you is a giant, beige building shaped like a Mesopotamian pyramid (the Ziggurat) and a thriving waterfront.
Naturally, you’d think you’re still in Sacramento. You’re not.
Most people—even some folks who have lived in Northern California for years—get tripped up on what county is West Sacramento in. They assume that because "Sacramento" is in the name, it must be part of Sacramento County.
Honestly? It's a fair mistake. But the second you cross that river, everything changes.
The Short Answer: It’s Yolo County
Basically, West Sacramento is in Yolo County.
The Sacramento River isn't just a place to watch the sunset or go boating; it is a hard legal boundary. To the east of the water, you have the City of Sacramento and Sacramento County. To the west, you enter the City of West Sacramento and Yolo County.
It’s a completely different jurisdiction. Different sheriff’s deputies. Different property tax collectors. Different election ballots.
If you get a speeding ticket on the I-80 bridge, which side of the river you're on determines whether you're dealing with the courts in Woodland or the ones downtown.
Why the Confusion is Actually Pretty Logical
There are a few reasons why people struggle with this. First off, the "916" area code. Usually, area codes follow county lines fairly closely, but West Sacramento shares the 916 (and the newer 279) with its neighbor across the water.
Then there’s the mail. If you’re sending a letter to someone in the Southport neighborhood, you’re writing "West Sacramento, CA." It feels like a suburb.

But the reality is that West Sacramento is its own independent city. It didn't even incorporate until January 1, 1987. Before that, it was a collection of smaller communities like Broderick, Bryte, and the Town of Washington.
When these spots finally teamed up to become one city, they stayed firmly planted in Yolo County.
A Quick Look at the Geography
The layout is kinda wild when you look at a map.
- North: Bordered by the Sacramento River and agricultural land.
- East: The Sacramento River (the big divider).
- South: Mostly open space and the deep water ship channel.
- West: The Yolo Bypass, which is basically a massive "relief valve" for floodwaters.
Because of the Yolo Bypass, West Sacramento is sort of an island. When the rains get heavy, that bypass fills up with water to protect the region from flooding, making the city feel even more distinct from the rest of the county.
Life in Yolo vs. Sacramento County
So, does it actually matter which county you're in?

Ask any business owner in the Port of West Sacramento and they'll tell you: yes. Yolo County has a very different "vibe" when it comes to governance. While Sacramento County is massive—home to over 1.5 million people—Yolo is smaller, more focused on agriculture, and arguably a bit more nimble.
West Sacramento residents often feel they get more "bang for their buck" in Yolo. The city has been aggressive about redevelopment. They’ve turned old industrial riverfronts into places like The Barn and Sutter Health Park (where the River Cats play).
There's a sense of pride in being the "cool younger sibling" to the big city across the river. You get the skyline views without the Sacramento City Hall bureaucracy.
Things to Know If You’re Moving or Visiting
If you're looking at real estate or just planning a trip to a game, keep these specific Yolo County quirks in mind:
- The County Seat: If you need to do official county business (like getting a marriage license or dealing with a court case), you aren't going to downtown Sacramento. You’re heading to Woodland. It’s about a 20-minute drive northwest.
- The Schools: Most of the city is served by the Washington Unified School District. It’s separate from the Sacramento City Unified District.
- Public Transit: You'll see Yolobus everywhere. While it coordinates with Sacramento’s RT, it is its own system.
- The Port: West Sacramento is home to a deep-water port. It’s a huge economic driver for Yolo County, bringing in rice, grain, and heavy machinery from all over the world.
What about the "East Yolo" Thing?
You might hear old-timers refer to the area as "East Yolo." Before 1987, that was the unofficial name for the area. It was basically the forgotten corner of Yolo County because it was so far removed from the agricultural hubs of Davis and Woodland.
Today, nobody calls it that. It’s West Sac.
Actionable Next Steps
Knowing what county is West Sacramento in is the first step to navigating the region like a pro. If you're actually planning to interact with the local government or move there, here is what you should do next:

- Check your jurisdiction: If you are looking at a house near the river, verify the parcel on the Yolo County Assessor’s website. Don't just trust a Zillow tag.
- Update your contacts: If you’re a business owner moving to the area, you'll need a Yolo County business license, not a Sacramento one.
- Explore the waterfront: Walk the River Walk Park. It’s the best way to see the physical divide between the two counties. You can stand on the West Sac side and literally look over at another county's jurisdiction.
- Follow local news: Because West Sac is in Yolo, it gets covered by the Daily Democrat (Woodland) as much as the Sacramento Bee.
It’s a unique spot. It’s got the grit of an old port town, the energy of a new tech hub, and a front-row seat to the capital of California—all while staying true to its Yolo County roots.
