About Mariners Island, San Mateo

Mariners Island is a bayside area in southeast San Mateo, located generally east of Highway 101 and south of Highway 92 along the Marina Lagoon, next to the Foster City border. It shares the 94404 zip code with Foster City and combines residential communities with offices, hotels and retail. Housing includes condominiums, townhomes and some single-family homes, many set along the lagoon or around landscaped common areas. Mariners Island real estate offers waterfront living with quick access to two major freeways.


Moving to Mariners Island

Moving to Mariners Island puts lagoon views, shopping centers and the Highway 92 and Highway 101 interchange all close at hand. Bridgepointe Shopping Center and other nearby retail centers cover groceries, dining and errands. Foster City's lagoons, parks and bay trail are just to the south and east. As a San Mateo Realtor, I help buyers compare Mariners Island condos and townhomes by association, amenities and lagoon access.


Cost of Living & Housing in Mariners Island

Mariners Island homes for sale are generally positioned in the more accessible to middle tier of the San Mateo market, depending on property type and water frontage. Most homes are condominiums and townhomes in communities built in the later decades of the 20th century, with some single-family homes on lagoon-side streets. Many communities offer shared pools, landscaped grounds and water views. Homeowners association dues, reserves and flood zone status are important to review for each property.

Schools & Education in Mariners Island

Mariners Island is within the City of San Mateo and is served by the San Mateo-Foster City School District and the San Mateo Union High School District.

Confirm school boundaries for any specific property with each district, since assignments can change over time.
