Foster City Real Estate & Living Guide

What's the Foster City, CA real estate market like right now? As of April 2026, the median sale price for a single-family home in Foster City is $2,475,000 — with homes selling at 108% of list price, in an average of just 4 days on market, and 1.3 months of supply. Note: April 2026 recorded only 2 single-family home sales in Foster City, so these figures should be read as directional rather than statistically definitive. The broader pattern — homes priced in the mid-to-high $2M range, selling over asking in days — is consistent with Foster City's track record.

Overview

Foster City occupies a genuinely unusual position on the Peninsula: it's a master-planned island community, built in the 1960s on Brewer Island at the eastern edge of San Mateo, engineered from bay marshland and organized around a 218-acre man-made lagoon system. The result is a city of about 32,000 people where many backyards end at a canal, where you can kayak from one neighborhood to another, and where the street names — Tarpon, Marlin, Catamaran, Sea Cloud — remind you constantly that you're living on water.

That origin story shapes everything about the housing market here. Foster City's 14 residential neighborhoods were all built within roughly a 20-year window between the late 1960s and mid-1980s, which means the housing stock is consistent in era but highly varied in what's been updated. A 1970s ranch backing to the lagoon can trade at $2.5M+ after a thoughtful renovation, while an interior home on the same street might sell for $400,000 less. Condition, view, and lot orientation matter enormously here.

Buyers come to Foster City for reasons that are easy to articulate: waterfront access without the Marin price tag, master-planned walkability, excellent safety ratings (Foster City consistently ranks among California's safest cities), and a central Peninsula location that puts San Francisco about 25 miles north and San Jose roughly 30 miles south. The community skews highly educated and internationally diverse — nearly 54% of residents identify as Asian, and the median household income exceeds $199,000 — which creates a tight-knit but cosmopolitan neighborhood character.

Compared to neighboring San Mateo, Foster City typically trades at a modest premium on a per-sale basis because its inventory is genuinely limited: there are no new neighborhoods to build, the land is fully developed, and turnover is low. Against the San Mateo County median of $2,167,500, Foster City's SFR market sits well above. However, at $1,045/sqft, Foster City's single-family homes actually run below the county's $1,227/sqft — because homes here tend to be larger (averaging 2,365 sqft) on modest lots averaging 5,671 sqft, so the absolute price per-home is high while the per-foot cost reflects larger floor plates.

Important caveat: With only 2 sales recorded in April 2026, Foster City's monthly figures carry significant margin of error — when the same two homes set both the median and the average, that's math, not a statistical sample. The 108% sale-to-list and 4-day DOM are consistent with recent Foster City norms, but the $2,475,000 price point should be verified against trailing 3–6 months of closed sales before using it to set a listing price or write an offer. The 8 active listings and 1.3 months of supply are more reliable signals: inventory is tight, and well-priced homes are moving fast.

Neighborhoods

The Islands

Foster City's most coveted address. Homes in The Islands — concentrated along streets like Triton Drive, Beach Park Boulevard, and the inner lagoon corridors — sit on or directly adjacent to the waterway, many with private docks. This is where you find homes with electric boat lifts, direct kayak access, and sunset views over the lagoon. Lot sizes here can be deceptive — the outdoor footprint lives much larger when the "backyard" is water. Pricing for waterfront homes regularly clears $3M and can push well above that on a premium lot with a recent remodel.

Bay Vista

Bay Vista sits along Foster City's western edge, with some homes looking out toward the San Francisco Bay. The housing stock is predominantly single-family detached, built in the 1970s and 1980s, ranging from 1,800 to 2,800 sqft. Buyers here pay a premium for the westward light and bay glimpses; median listing prices in Bay Vista cluster around $1.9M–$2.1M. Streets are wider here than in the island interior, and the neighborhood has a quieter residential character — less through-traffic, more families who've been here for 20+ years.

Carmel Village

One of Foster City's more established single-family neighborhoods, Carmel Village features some of the city's larger lots and more generously scaled homes. Expect 1970s and 1980s construction, homes typically running 2,000–3,000 sqft, with more mature landscaping than newer Bay Area subdivisions tend to have. Median listing prices run around $2.0M. This is a well-maintained interior neighborhood — no direct water frontage — but it's a short walk to the lagoon trail system and Leo J. Ryan Park.

Marina Point

Marina Point is a mix of single-family homes and townhomes, concentrated in the southern portion of the city near the lagoon's largest open stretch. Some Marina Point properties have partial water views and canal access; others are interior. The neighborhood tends to attract buyers who want the Foster City lifestyle at a slightly more accessible price point than The Islands — think $1.7M–$2.2M for single-family depending on lot position and updates.

Marlin Cove

Marlin Cove is a blend of condos and single-family homes, with a portion of the neighborhood offering private dock access to the lagoon channels. The single-family stock here runs smaller than Carmel Village — many homes are under 2,000 sqft — which makes it one of the more accessible entry points into Foster City's SFR market. Townhome and condo buyers often look here first; prices for attached units can start in the $1.2M–$1.5M range.

Isle Cove

Isle Cove is Foster City's most apartment- and condo-dense area, featuring high-rise and mid-rise complexes as well as some townhome communities. For buyers who want Foster City's amenities and lagoon access without a detached home price tag, this is where to look. Condos here can start in the high $700,000s and scale up depending on unit size and waterfront position. It's also the neighborhood most favored by younger professionals and those who want a walkable, lower-maintenance lifestyle.

Pilgrim-Triton

Pilgrim-Triton sits in the northern part of Foster City and anchors the city's most mixed-use, professionally oriented section — it's close to many of the office campuses and has a higher density of apartments, townhomes, and smaller condos. Buyers looking for a lower price point entry into Foster City, or renters transitioning toward ownership, often start here. The neighborhood is convenient to Highway 92 and the SamTrans and shuttle connections.

Treasure Isle

Treasure Isle is a mid-city neighborhood with a mix of single-family homes and some attached product. It's a practical, well-connected neighborhood — good access to the lagoon trail, close to the city's schools and parks, and a reasonable walk to Foster City's commercial corridor on East Hillsdale Boulevard. Pricing in Treasure Isle for single-family homes tends to run $1.8M–$2.2M depending on lot size and condition.

Getting Around

Caltrain: Foster City does not have its own Caltrain station. The nearest stop is the Hillsdale station in San Mateo, roughly a 10-minute drive or a short SamTrans bus ride. A city-sponsored Foster City Commuter Shuttle connects the Hillsdale station to residential neighborhoods and major employers weekday mornings and evenings. Hillsdale is not a Baby Bullet stop, which means express trains skip it — plan on a local service commute to San Francisco (approximately 45–55 minutes) or San Jose (~40 minutes southbound).

BART: There is no BART station in Foster City, but the North Foster City Shuttle operates service to the Millbrae BART/Caltrain intermodal station, which provides SFO access and direct BART service into San Francisco. For BART-dependent commuters, the Millbrae connection is functional but adds transit legs.

SamTrans FCX Express: The Foster City Express (Route FCX) runs weekday express bus service directly between Foster City and downtown San Francisco on US-101, with five morning departures from Foster City and six afternoon return trips. It's a practical car-free option for downtown SF workers — the ride runs roughly 45–60 minutes depending on traffic.

Highways: State Route 92 bisects Foster City east-to-west and connects directly to US-101 on the west side, providing north-south access to San Mateo (north) and Redwood City/Silicon Valley (south). SR-92 also crosses the San Mateo-Hayward Bridge, making Foster City one of the Peninsula's better-positioned cities for Fremont and East Bay commuters. Rush-hour backup at the toll plaza is real, and eastbound commuters should plan accordingly. US-101 is the primary northbound arterial to San Francisco.

El Camino Real: El Camino Real runs north-south on the western edge of Foster City's adjacent area, connecting to downtown San Mateo to the north and Redwood City to the south. Most day-to-day errands in Foster City are handled via East Hillsdale Boulevard, the city's main commercial spine.

San Francisco: Foster City is approximately 25 miles from downtown San Francisco. By car on US-101 in off-peak traffic, the drive runs 25–30 minutes. During peak commute hours, expect 45–60 minutes northbound. By transit via the FCX express bus, allow 50–65 minutes door-to-door.

Schools

K–8: Foster City students attend the San Mateo-Foster City School District, which serves the city with several elementary schools including Foster City Elementary, Brewer Island Elementary, and Audubon Elementary. The district is well-regarded across the Peninsula for solid academics and consistent attendance rates. As of early 2026, district-wide average daily attendance exceeds 95%.

Middle school: Bowditch Middle School, located at 1450 Tarpon Street in Foster City, serves the district's 6th through 8th graders. Bowditch is within the San Mateo-Foster City School District, and test score data shows 72% of students proficient in math and 75% in reading — performance that tracks with the city's high household education levels.

High school: Foster City students feed into the San Mateo Union High School District. Most Foster City students attend San Mateo High School. The SMUHSD encompasses several high schools across San Mateo, and school assignment is address-based.

School assignment is address-specific and district boundaries change. If schools drive your decision, verify your exact address against the current district boundary maps before writing an offer.

Life in Foster City

The defining experience of living in Foster City is the lagoon. It's not a decorative amenity that residents admire from afar — it's 218 acres of navigable water with 16.5 miles of interconnected channels that people actually use. On a weekend morning, you'll see kayakers, stand-up paddleboarders, and electric boats moving through the channels between neighborhoods. The city operates equipment rentals from Leo J. Ryan Memorial Park, and only human-powered, sail, or electric craft are permitted, so the lagoon stays quiet and pleasant year-round.

Leo J. Ryan Memorial Park is the city's civic center of gravity — a waterfront park with playing fields, walking paths, a playground, and direct lagoon access that functions as Foster City's town square. The city has 21 parks in total, which is an extraordinary ratio for a city of 32,000. The Bay Trail passes through Foster City's eastern shoreline, connecting to the broader 500-mile regional trail network around the bay.

The commercial core along East Hillsdale Boulevard and the Edgewater Place shopping area handles most daily needs — there are grocery options, restaurants ranging from local neighborhood spots to national chains, and professional services — but Foster City is not a walkable downtown city in the way San Carlos or Burlingame are. Most residents drive for shopping and dining. What the city does offer in place of a walkable downtown is an unusually quiet, low-traffic residential environment and a safety record that consistently ranks it among California's top-10 safest cities.

The single largest employer in Foster City is Gilead Sciences, the global biopharmaceutical company headquartered here. Gilead's campus employs thousands of people in Foster City and draws a highly educated, internationally diverse workforce that shapes the city's demographics and community character. Visa, Sony Interactive Entertainment, and other major tech and financial firms also maintain a significant Foster City presence. The city's weekday energy reflects that employer base — more quiet-suburban than buzzy-commercial.

What Homes Look Like

• The Islands / Lagoon-fronting — Late 1960s–1980s single-family, 1,800–3,200 sqft, most with direct canal or lagoon access and private docks; extensively remodeled examples command significant premiums
• Bay Vista / Carmel Village / Treasure Isle — 1970s–1980s ranch and two-story SFRs, 1,800–2,800 sqft, on lots averaging 5,000–7,000 sqft; condition ranges widely
• Marina Point / Marlin Cove — Mix of single-family (1,400–2,200 sqft) and townhomes; some canal-facing units with dock access
• Isle Cove / Pilgrim-Triton — Mid-rise and high-rise condo complexes, townhomes, and apartment buildings; studios through 3BR; most common entry point for attached-product buyers

Rough price tiers, April 2026 (approximate):

• Entry condos/townhomes: ~$750,000–$1,300,000 (studios and 1–2BR condos in Isle Cove and Pilgrim-Triton; 2–3BR townhomes in Marlin Cove and Marina Point)
• Entry single-family: ~$1,700,000–$2,000,000 (interior SFRs in Treasure Isle, Marlin Cove, or original-condition homes in Carmel Village)
• Mid-tier single-family: ~$2,000,000–$2,600,000 (updated SFRs in Carmel Village, Bay Vista, Marina Point)
• Upper-tier / waterfront: ~$2,600,000–$3,500,000+ (lagoon-fronting or canal-access SFRs in The Islands and Bay Vista, particularly with private docks and modern renovations)

Tiers are approximate, derived from SAMCAR MLS data and local listing activity for April 2026. Individual properties vary widely by view, lot, condition, and water access.

What to Know Before You Buy or Sell

Small sample size — treat monthly data carefully. Foster City typically records only 5–20 single-family home sales per month. April 2026's 2-sale count is at the extreme low end. Before pricing a listing or structuring an offer, pull 6 months of closed sales rather than relying on any single month's snapshot. The data will be more meaningful with a larger trailing window.

Flood risk is real, even with the levee. FEMA currently classifies Foster City as Zone X — mandatory flood insurance is not required — because the city's levee is certified to withstand the 1% annual chance flood event. However, flood risk models suggest that 98% of properties face meaningful flood exposure over a 30-year horizon, and the levee itself requires ongoing maintenance and investment. Buyers should understand that Zone X status is a FEMA determination tied to the levee's current condition, not a permanent guarantee. Purchasing optional flood insurance is worth the conversation with your insurance agent.

The lagoon adds value and complexity. Waterfront and canal-adjacent properties typically sell for $300,000–$600,000 more than comparable interior homes. But they also come with additional due diligence: dock permits and maintenance, potential HOA rules governing watercraft, and the structural condition of any bulkhead or retaining wall on the lagoon edge. Pull permit history and get a specialist inspection on any water-adjacent property.

No Caltrain station in Foster City. Transit-dependent buyers should map their specific commute before falling in love with a house. The Hillsdale shuttle and FCX bus are workable options, but they add time and logistics compared to cities with direct Caltrain access. If your job requires daily Caltrain use, model the full door-to-door commute honestly.

Bridge commuters have a genuine advantage here. SR-92 and the San Mateo-Hayward Bridge make Foster City one of the easiest Peninsula cities for commuters heading to the East Bay — Fremont, Hayward, Dublin, or even Oakland. If your job is across the bay, Foster City's location is genuinely superior to most Peninsula alternatives.

HOAs are common but not universal. Condo and townhome communities in Isle Cove and Pilgrim-Triton almost universally have HOAs; many waterfront SFRs in The Islands also have HOAs that govern dock use, lagoon access, and exterior maintenance. Review HOA financials, meeting minutes, and pending special assessments carefully. Some Foster City HOAs also maintain the adjacent lagoon channels, which means shared infrastructure cost exposure.

Housing stock is almost entirely 1960s–1980s construction. There is essentially no new construction in Foster City — the land was built out decades ago. Every home you're buying has decades of history. Permit compliance, any unpermitted additions, seismic retrofitting, and updated electrical are standard items to check in your inspection phase.

Frequently Asked Questions

What is the median home price in Foster City, CA? As of April 2026, the median sale price for a single-family home in Foster City is $2,475,000 per SAMCAR/MLSListings data — though April 2026 recorded only 2 closed sales, which limits the statistical reliability of that figure. The trailing 6-month median and comparable sales from neighboring months give a more accurate picture; Foster City SFRs have been consistently trading in the $2.0M–$2.8M range depending on water access and condition. For condos and townhomes, prices typically range from $750,000 to $1.5M.

Is Foster City a buyer's or seller's market? As of April 2026, it's a seller's market — homes are selling at 108% of list price in an average of 4 days, with only 1.3 months of supply. That said, low volume (only 2 SFR sales in April) means individual listings carry outsized influence. Well-priced, updated homes in desirable water-adjacent positions continue to draw competitive offers; overpriced or deferred-maintenance homes can sit. Know the difference before you price or bid.

What makes Foster City different from other Peninsula cities? The lagoon. Foster City is the only city in San Mateo County built around an engineered inland waterway system, with direct kayak and boat access from hundreds of homes. That physical infrastructure — 218 acres of navigable water, 16.5 miles of channels — creates a lifestyle that no amount of money can buy in other Peninsula cities. It also keeps inventory perpetually tight: there's nowhere to build more, and residents tend to stay.

What neighborhoods are in Foster City? Foster City has 14 distinct residential neighborhoods, the most active in real estate being: The Islands (waterfront, highest prices), Bay Vista (bay views, premium SFRs), Carmel Village (established, larger lots), Marina Point (mixed SFR and townhome), Marlin Cove (mixed attached/detached), Isle Cove (condo-dense, most affordable entry point), Pilgrim-Triton (mixed-use, transit-convenient), and Treasure Isle (mid-city, family-friendly).

How are Foster City's schools? Foster City K–8 students attend the San Mateo-Foster City School District, which includes Foster City Elementary, Brewer Island Elementary, Audubon Elementary, and Bowditch Middle School. The district maintains over 95% average daily attendance and solid state test scores. High school students attend San Mateo Union High School District schools, most commonly San Mateo High School. School assignment is address-specific — verify your address against current district boundary maps before writing an offer.
