Homes in Portola Valley
Portola Valley sits on the San Andreas fault, and most of its houses are on hillside lots where the town’s ASCC or a neighborhood design committee watches the outside. Four kinds of house come up most, and the first question is whether your street is in the town, in an HOA, or in the county.
1950s–60s ranches on one-acre hillside lots
Westridge, Alpine Hills, Central Portola Valley. Single-story houses stepping down a slope, often with a crawlspace on the downhill side. Westridge has its own architectural committee for anything visible outside.
1970s Portola Valley Ranch homes
Portola Valley Ranch. About 205 clustered, wood-sided houses built from fourteen original models. Exterior changes go through the Ranch Design Committee and then the town.
1920s summer cabins grown into houses
Los Trancos Woods and Vista Verde (unincorporated). Small lots, septic systems first sized for seasonal use, and permits from San Mateo County, not the town.
Postwar modern homes
Ladera (unincorporated). Late-1940s and 1950s modern houses, including a small group of 1951 Eichlers with plumbing in the slab; permits through San Mateo County.
