Living in Foster City, CA: A Buyer's Guide to Lagoon Homes, Townhomes, and Condos

Foster City is unlike anywhere else on the Peninsula. Instead of growing street by street over a century, it was planned almost all at once. Starting in the early 1960s, developer T. Jack Foster and his family turned Brewer Island, a stretch of reclaimed marshland on the edge of the bay, into a community of lagoons, parks, and neighborhoods designed together. The city incorporated in 1971.That history explains almost everything about living here: the flat streets and waterfront paths, the large share of townhomes and condos, the homeowners associations, and the questions buyers should ask about water and soil. Before real estate, I spent five years as a construction superintendent, so this guide covers both what daily life is like in Foster City and what I look at closely in its homes.

The big picture

**Built around water:** a network of lagoons runs through the city, with walking and biking paths along the shoreline and the Bay Trail around the edge
**Flat and easy to get around:** wide streets, bike lanes, and parks such as Leo J. Ryan Park at the center of town
**Commute access:** Highway 92 and Highway 101 run along the city, and the San Mateo Bridge makes the East Bay one of the easier cross-bay commutes on the Peninsula
**Transit:** there is no Caltrain station in Foster City, but the Hillsdale station in San Mateo is a short drive away
**Employers:** major companies, including Gilead Sciences, are headquartered here, so some residents can live close to work

Types of homes in Foster City

Because the city was planned, its housing falls into a few clear types, each with its own pros and things to check.

Lagoon-front single-family homes

Some of the most sought-after homes in Foster City back right onto the lagoon, with private docks or water views from the backyard. Many were built in the 1960s and 1970s.**What I look at here:** the shoreline edge. Ask who is responsible for maintaining the bulkhead or seawall along the back of the property, what condition it is in, and whether any dock was permitted. Repairs to a waterfront edge can be costly. I also look for signs of settlement, such as cracks in the slab, uneven floors, and doors that stick.

Interior single-family homes

Away from the water, Foster City has neighborhoods of single-family homes on quiet streets and cul-de-sacs, also largely from the 1960s through the 1980s. Some are in neighborhoods with an HOA, and some are not, so confirm this for each home.**What I look at here:** homes from this era have their own checklist. Some houses built in the late 1960s and early 1970s used aluminum branch wiring, which needs a qualified electrician's evaluation. Some homes from the late 1970s through the mid-1990s used polybutylene water pipes, which are known to fail with age. I also check roofs, windows, water heaters, and any past remodels for permits.

Townhomes and condos

Townhome and condo communities make up a large share of Foster City's housing, and they are often the most approachable way to buy into the city. Many have shared pools, green space, and lagoon access.**What I look at here:** in these communities, the HOA matters as much as the unit. I review the reserve study, budget, insurance, special assessments, and the last year of meeting minutes. Roofs, siding, and balconies are often shared expenses, and California now requires inspections of balconies and other elevated wood structures in many condo buildings, so ask for that report.

Water, soil, and earthquakes

Because Foster City sits on former bay land just a few feet above sea level, buyers should understand three things:

**Levees and flood risk.** The city is protected by a levee system, and in 2020 voters approved funding to raise and strengthen it for current flood standards and future sea level rise. Flood zone status and flood insurance requirements can still vary by address, so check the flood zone for the specific home and get insurance quotes early.
**The lagoon's role.** The lagoon is not only scenery. It is also part of the city's stormwater system, with water levels managed and pumped to the bay.
**Soil in an earthquake.** Filled land can behave differently during strong shaking. Read the Natural Hazard Disclosure report, which shows whether a property is in a mapped liquefaction zone, and ask about the foundation type and any past settlement repairs.

None of this is a reason to avoid Foster City. It is a reason to buy with your eyes open, and to budget for insurance and maintenance accurately.

Schools

Foster City is served by the San Mateo-Foster City School District for elementary and middle school, including Bowditch Middle School in Foster City, and by the San Mateo Union High School District for high school. Attendance areas are set by address and can change, so always confirm the assigned schools directly with the districts before you buy. No agent can guarantee a school assignment.

How to approach buying in Foster City

**Decide on the home type first.** Lagoon-front, interior single-family, and townhome or condo each come with different costs and responsibilities.
**Read the HOA documents closely,** even for some single-family homes. Dues, reserves, and rules shape your real monthly cost.
**Check flood zone, insurance, and the Natural Hazard Disclosure early**, before you remove contingencies.
**Match inspections to the era of the home:** wiring and plumbing for 1960s to 1990s homes, the shoreline edge for waterfront homes, and the building's shared systems for condos.
**Test your commute** over 92, 101, or the San Mateo Bridge at the times you would actually drive.
