Ever driven south from San Francisco, hit that wall of fog, and wondered exactly where you were? You aren't alone. One minute you're passing the colorful Victorians of the Outer Mission, and the next, you’re seeing rows of pastel "little boxes" perched on hillsides. People ask all the time: what county is Daly City in? Most folks assume it’s just another neighborhood of San Francisco. It feels like it. The BART trains zip right through, and the city streets seem to bleed into one another without a clear break. But honestly, the answer is a bit more distinct. Daly City is in San Mateo County.
It sits right at the northernmost tip of the county, serving as the literal "Gateway to the Peninsula." While it shares a long, jagged border with the City and County of San Francisco, Daly City maintains its own identity, its own government, and a vibe that is uniquely "San Mateo."
The "Gateway" That Confuses Everyone
If you're standing on one side of a street in the Crocker neighborhood, you might be in San Francisco. Cross the street, and suddenly you’re in Daly City. It’s that close. Because of this proximity, a lot of people mistakenly label it as part of the SF urban sprawl.
But here’s the kicker: Daly City is actually the largest city in San Mateo County by population. With over 100,000 residents, it’s a heavy hitter in the region. It’s not just a suburb; it’s a hub for healthcare, retail, and some of the best dim sum you’ll ever find in Northern California.
Why the County Line Matters
You might think, "Who cares about a line on a map?" Well, if you live there, you care. Taxes, school districts, and even how often the trash gets picked up change the second you cross that San Mateo County line.

San Mateo County is known for being one of the wealthiest and most diverse pockets of California, stretching from the tech campuses of Silicon Valley in the south all the way up to the foggy cliffs of Daly City. Being in San Mateo County gives Daly City residents access to a different set of services and a slightly different political climate than their neighbors to the north.
A City Born From an Earthquake
Daly City didn't just appear out of nowhere. It has a bit of a dramatic origin story. Before 1906, the area was mostly rolling hills and dairy farms. Then, the Great San Francisco Earthquake hit.
Thousands of people fled the fires and rubble of San Francisco, heading south. A local dairyman named John Daly—yeah, that’s where the name comes from—opened his land to the refugees. He gave them milk, bread, and a place to stay. Many of those folks decided they liked the fresh air (and the lack of falling buildings) and stayed for good.
By 1911, the residents were worried that San Francisco would try to annex them. They wanted to keep their autonomy. So, they officially incorporated as Daly City, firmly planting their flag in San Mateo County territory.
The Fog and the "Little Boxes"
If you’ve ever heard the song "Little Boxes" by Malvina Reynolds, she was talking about Daly City—specifically the Westlake district. After World War II, a developer named Henry Doelger started building mass-produced, mid-century modern homes.
- They were affordable.
- They were stylish for the time.
- They were built on what used to be cabbage patches and sand dunes.
Today, those "little boxes" are iconic. They represent a specific era of California's growth. And yes, they are almost always covered in a thick blanket of Pacific fog. If you're visiting, bring a jacket. Seriously. Even in July, that San Mateo County coastline doesn't play around.
What to Actually Do in Daly City
Since it's in San Mateo County, you get a mix of urban convenience and rugged coastal beauty. It’s not all just houses and fog.
The Cow Palace
Believe it or not, the world-famous Cow Palace is actually in Daly City, not San Francisco. It’s hosted everything from The Beatles and Elvis Presley to the Grand National Rodeo. It’s a bit of a legend in the Bay Area. If you’re into weird history, this is your spot.
Thornton State Beach
Looking for those dramatic California cliff views? Head to the edge of the city. Thornton State Beach offers trails that overlook the Pacific. It’s rugged, windy, and gorgeous. It’s also a prime spot for hang gliders who launch off the cliffs at nearby Mussel Rock.
The Food Scene
Daly City is arguably the Filipino food capital of the United States. Because of the huge Filipino-American population in this part of San Mateo County, you can find incredible sisig, adobo, and halo-halo on nearly every corner.
- Original Joe’s Westlake: A local institution for Italian-American comfort food.
- Koi Palace: Famous for dim sum that people will wait hours for.
- Fil-Am Cuisine: Where you go for authentic, no-frills BBQ skewers.
Life on the Edge: San Mateo vs. San Francisco
Living in Daly City means balancing two worlds. About half the workforce commutes into San Francisco for jobs, taking the BART or the 280 freeway. But when they come home, they’re paying San Mateo County property taxes and dealing with San Mateo County courts.
It’s often a "hidden gem" for people who want to be near the action of SF but can't stomach the rent. While Daly City isn't exactly "cheap" (it’s still the Bay Area, after all), it’s generally more accessible than the city to the north.
Public Transit and Commuting
The city is incredibly well-connected.
- BART: Two stations (Daly City and Colma) serve the area.
- SamTrans: The bus system for San Mateo County.
- Muni: Some San Francisco bus lines actually cross the border to drop people off.
This connectivity is why it's called the "Gateway." You can be in downtown San Francisco in 20 minutes, or at San Francisco International Airport (which is also in San Mateo County!) in about 15.
Actionable Tips for Visiting or Moving
If you’re planning to spend time in this corner of San Mateo County, here’s how to do it right:
- Layer up: The temperature can drop 10 degrees the moment the fog rolls in. A light windbreaker is your best friend.
- Check the zip code: Daly City shares several zip codes with neighboring towns like Colma and SF. If you’re looking at real estate, make sure you know exactly which side of the line you’re on.
- Explore the parks: Don't just stay on Mission Street. Get out to San Bruno Mountain State Park for a view of the entire Bay Area.
- Eat local: Skip the chains. Go to the small mom-and-pop spots in the "Top of the Hill" district.
Daly City might be in San Mateo County on paper, but in spirit, it’s a bridge between the old-school Peninsula and the ever-changing city of San Francisco. It's a place defined by its people, its history, and—of course—that relentless, beautiful fog.
To get a true feel for the area, your next move should be a drive down Skyline Boulevard. It’s the best way to see the transition from the rugged Pacific cliffs to the meticulously planned neighborhoods that put this county on the map. You can also head over to the Daly City History Museum on Mission Street to see photos of the original dairy farms before the "little boxes" took over.
