Living in Harbor Side
Harbor Side is Foster City's official Neighborhood #6, which also includes Whalers Cove, Whalers Landing and Ponderosa Shores. It was built mostly in the 1970s, and about half of its single-family homes are right on the water, with the rest of its sales coming from townhomes and condos. Single-family homes are among Foster City's higher-priced, with a 12-month median around $2.67M, while the condo and townhome median was about $1.24M in 2025.
Parking & walkability: Single-family homes typically have attached two-car garages, and townhome and condo complexes include assigned parking with more limited guest spaces. The neighborhood is flat, with lagoon-side paths and the Bay Trail nearby, so walking and biking are easy. Everyday shopping is a short drive or bike ride, and Highway 92 and Highway 101 are a few minutes away.

Borders are built lot by lot from the county's property lines and where homes have been listed (MLS neighborhood codes), and stay inside official city limits (dashed), so a home or two along an edge may differ from official MLS lines.
