If you want to be close to San Francisco, major employers, the airport, and the Bay Area’s innovation economy without paying the very highest prices in the county, these affordable cities in San Mateo County deserve a serious look.
Affordable is always relative here. We are still talking about San Mateo County , one of the most expensive places in the country to buy real estate. But within that context, there are three standouts that consistently offer better value than many neighboring cities: South San Francisco , San Bruno , and Daly City.
Each one gives you a different version of affordability, convenience, and lifestyle. One is a biotech powerhouse. One is a practical, community-oriented airport city with strong shopping and transit access. One offers the lowest pricing in the county along with dramatic coastal access and big-city convenience.
If you are searching for affordable cities in San Mateo County, this is where we would start.

Why These Are the Most Affordable Cities in San Mateo County
When people hear the phrase affordable cities in San Mateo County, they sometimes assume there must be a catch. And honestly, there usually is a tradeoff somewhere. In this part of the Peninsula, pricing is incredibly nuanced.
What tends to push values lower in these three cities compared with other parts of the county is a mix of factors such as:
- Cooler, foggier weather in many neighborhoods
- Wind exposure, especially in areas closer to the coast
- Airport proximity in some locations
- More working-class and industrial history in certain pockets
- Less polished or less sunny reputations than some of the county’s pricier cities
But here is the key point: lower price does not mean low quality of life.
These cities are still incredibly well located. You are near San Francisco. You have access to major freeways, BART or Caltrain depending on the city, strong employment hubs, shopping, parks, and in some cases stunning coastal recreation. For a lot of buyers, that tradeoff pencils out very well.
South San Francisco: Affordability Close to Biotech and SFO
South San Francisco is one of the most practical choices among the affordable cities in San Mateo County, especially for anyone tied to biotech, life sciences, or frequent travel.
This city has about 60,000 people and sits roughly two and a half miles south of San Francisco. It is bordered by San Bruno Mountain to the north, the Bay to the east, the Pacific side to the west, and San Bruno to the south. That geography gives it a little bit of everything, from industrial corridors to residential hillsides to sunny pockets that surprise people.
South San Francisco is famously known as The Industrial City. That nickname sticks, but it does not tell the whole story. Yes, there is light industry here. But there are also a lot of appealing neighborhoods and a very diverse housing stock.
One of the biggest reasons people move here is simple: work.
Why South San Francisco Stands Out
South San Francisco is one of the most important biotech hubs in the United States. There are more than 200 biotechnology companies here, including major names like:
- Genentech
- Pfizer
- AstraZeneca
- 23andMe
The city already has over 11.5 million square feet of lab and office space, with another roughly 5 million square feet approved for future development. That is an enormous employment base, and it creates a very compelling live-near-work equation.
In the Bay Area, a five- to ten-minute commute can feel like a luxury. That is one reason many buyers who work in biotech choose South San Francisco over other Peninsula locations.
Another major advantage is proximity to SFO. If you travel often or have colleagues flying in and out, being around ten minutes from the airport is hard to beat.
Downtown South San Francisco
Grand Avenue gives South San Francisco some real personality. It has good local restaurants, mom-and-pop businesses, and a sense of history that connects back to the late 1800s, when the railroad helped spur development here.
The downtown area also continues to evolve. New apartment buildings are going up, and the city feels like it is still adding to its identity rather than standing still.
One of the standout local gems is La Tapatia, a spot that clearly has a strong following. A line out the door at lunch is always a good sign, especially in a county where that kind of crowd is not the norm in every downtown.
What Homes Cost in South San Francisco
For buyers focused on affordable cities in San Mateo County, South San Francisco offers meaningful savings compared with countywide averages.
- 2023 median sale price: about $1,230,000
- County average comparison: about $1.8 million
- Lowest sale price: about $700,000
- Highest sale price: about $1.9 million
- Typical condo range: roughly $600,000 to $1 million
That pricing puts South San Francisco in a sweet spot for buyers who want access to San Francisco and Peninsula job centers without jumping into the cost structure of cities farther south.
If your priority list includes convenience, employment access, and decent value by Peninsula standards, South San Francisco is easy to justify.
San Bruno: A Convenient Community With Solid Value
San Bruno is often overlooked, but it absolutely belongs on any shortlist of affordable cities in San Mateo County.
With around 42,000 residents, San Bruno is smaller than Daly City and South San Francisco, but it offers a great central location. It sits about 12 miles south of San Francisco, just north of Millbrae and just south of South San Francisco. You have the Bay to the east, mountains behind you, and the coast only a few minutes away.
It is known as the Airport City, and for good reason. You are very close to SFO. That convenience matters a lot for people who travel for work, commute regionally, or simply want fast access to the rest of the Bay Area.
What Living in San Bruno Feels Like
San Bruno has a strong community feel. It is the kind of place where many people grew up, and their families stayed. That says a lot.
Downtown along San Mateo Avenue has local shops, restaurants, and a slightly quirky, approachable vibe. It does not feel overly polished, and that is part of the charm.
There is also a local landmark feel to Artichoke Joe’s, the longtime casino that has been part of the city’s story for generations.
From a practical standpoint, San Bruno checks a lot of boxes:
- Caltrain access runs through the city
- Tanforan provides major shopping, restaurants, and a movie theater
- Shops at San Bruno Park and nearby centers make errands easy
- Skyline College is nearby and notable for its highly regarded cosmetology program
On the employer side, San Bruno benefits from having major corporate presence, including:
- YouTube
- Walmart.com
For a lot of homebuyers, that matters just as much as lifestyle. Living close to work can dramatically improve your day-to-day routine.
Housing in San Bruno
San Bruno has a broad mix of housing styles. You will see plenty of ranch homes, along with mid-century properties and other classic Peninsula architecture.
Pricing is still high by national standards, but among the affordable cities in San Mateo County, it offers a balanced middle ground.
- 2023 average and median price: about $1,375,000
- Lowest sale price: about $700,000
- Highest sale price: about $2.4 million
- Typical single-family sweet spot: about $1.3 million to $1.8 million
That range makes San Bruno more expensive than South San Francisco and Daly City on average, but many buyers find the location and everyday convenience worth the premium.
Parks, Culture, and Daily Life
San Bruno also has more recreational and civic amenities than people sometimes expect.
- San Bruno City Park is the city’s largest park and includes picnic areas and play spaces
- Commodore Park offers playgrounds, a baseball diamond, and a fully enclosed dog park
- The library supports a community art gallery program in its main reading room
- The San Bruno Aquatic Center has generated a lot of excitement locally
If what you want is a city that feels usable, connected, and community-oriented, San Bruno deserves more attention than it usually gets.
Daly City: The Most Affordable Option in the County
Among all the affordable cities in San Mateo County, Daly City is the lowest-priced option of the three.
It is also the largest by population, with about 106,000 residents, making it the second most populous city in the county. Daly City is mostly residential, though it is also home to major commercial areas and excellent recreation.
Geographically, it is in a strong spot. Daly City sits just south of San Francisco, bordered by Pacifica to the south and San Bruno Mountain to the east. That gives you access to both urban convenience and outdoor escapes.
What Makes Daly City Different
Daly City does not really have the traditional downtown core you get in South San Francisco or San Bruno. Instead, it is organized around neighborhoods and major retail centers.
The two biggest shopping anchors are:
- Serramonte Center, a massive indoor shopping destination with major tenants and ongoing expansion
- Westlake Shopping Center, an outdoor center with practical stops like Walgreens and Trader Joe’s
If you know Daly City, you know Serramonte can get busy. Weekend parking can be an adventure. But that also tells you something useful: the amenities here are substantial.
Daly City also has a lot of community infrastructure packed into one city:
- Four library branches
- A large movie theater at Westlake
- A farmers market that is one of the oldest in the county
- The Cow Palace, a historic arena known for events, fairs, and concerts
Outdoor Access Is a Huge Plus
One thing that makes Daly City especially compelling is its access to the coast and open space.
There are some truly beautiful spots here, including:
- Thornton State Beach with coastal views and equestrian trails
- Mussel Rock and Mussel Rock Park Beach, known for connected trails and paragliding launch points
- Crocker Gate Trailhead, which connects to San Bruno Mountain State Park
- Marchbank Park, a neighborhood park with sports facilities and picnic areas
- Lake Merced nearby for running, hiking, kayaking, and golf
- Fort Funston just north of the city, one of the most dog-friendly places in the Bay Area
That is a pretty remarkable mix. Daly City can be practical and scenic at the same time.
What Homes Cost in Daly City
If price is your main concern and you want to stay in this part of the Peninsula, Daly City is the leader among the affordable cities in San Mateo County.
- 2023 average and median sale price: just under $1,170,000
- Lowest single-family sale price: about $590,000
- Highest single-family sale price: about $2 million
- Typical condo range: about $400,000 to $1 million
That lower entry point, especially for condos, opens the door for buyers who may be priced out elsewhere in the county.
The city’s neighborhoods are generally appealing, though topography matters. Daly City is not especially flat overall. You are more likely to encounter rolling hills and elevation changes than perfectly level streets.
How Weather Affects Home Prices in These Cities
One of the biggest reasons these are the most affordable cities in San Mateo County comes down to weather.
On a bright, clear day, all three cities can look fantastic. But that is not the whole story. In many neighborhoods, especially those closer to the ocean influence, you can expect:
- More fog
- More wind
- Cooler temperatures
- Less consistent sunshine than warmer Peninsula cities
That weather pattern affects demand, and in turn, pricing.
In San Mateo County, every incremental jump in budget tends to buy something materially better, whether that means more sun, a more prestigious school district, a flatter lot, a more polished downtown, or a stronger perceived lifestyle premium. That continues until you hit the upper price ranges around $2.5 million to $3 million and beyond.
So if you are comfortable with cooler weather and occasional gray skies, these cities can represent some of the best value in the county.
Which of These Affordable Cities in San Mateo County Is Right for You
