Living in 19th Avenue Park & Sunnybrae
19th Avenue Park & Sunnybrae sit in central San Mateo between the Caltrain line and Highway 101. In 1953 the land was owned by Leslie Salt, whose real estate arm sold it for development, and much of 19th Avenue Park was built by Joseph Eichler just as he was hitting his stride, bringing his California Modern homes to middle-class buyers. Today the flat streets hold a mix of those Eichlers and other postwar homes, many updated or expanded. It's one of San Mateo's busier and more competitive markets: 49 sales in the last 12 months at a median around $1.92M, with 2026 sales so far averaging about 111% of asking, and the median rose about 68% from 2015–16 to 2024–25, ahead of the city's 63%.
Parking & walkability: Most homes have a driveway and a garage, and street parking is generally easy on the residential blocks. The flat streets make biking easy, Central Park and downtown San Mateo are a short ride away, and the Hayward Park Caltrain station, Highway 92 and 101 are all close by.
