Eastern Addition & Downtown San Mateo, CA
Downtown San Mateo and the historic Eastern Addition, mostly condos plus older single-family homes.
Living in Eastern Addition & Downtown
Eastern Addition & Downtown covers downtown San Mateo and the older neighborhood around it, with homes from many eras. It has a Hollywood footnote: in the silent-film era, Pacific Studios built a state-of-the-art studio here and made a half-dozen films in seven years before talkies made it obsolete, and its original office building still stands at 430 Peninsula Avenue. Today it's a mix of older single-family homes and a much larger number of condos. Single-family homes have a 12-month median around $1.62M, while condos have ranged widely, from a 2025 median around $585K to a 2026 median so far around $828K.
Parking & walkability: Older homes often have a single-car or detached garage, and condo buildings include assigned or garage parking; street parking downtown is busy and partly metered. This is San Mateo's most walkable area: downtown's restaurants and shops, Central Park and the San Mateo Caltrain station are all steps 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.
