Saranap straddles the border between Walnut Creek and Lafayette in zip 94595. Technically unincorporated Contra Costa County, it's a quieter pocket of larger lots and a mix of custom and mid-century homes — often more house for the money than neighboring Walnut Creek or Lafayette proper.
Housing stock in Saranap is a mix: 1950s ranch on the flatter parts, 1970s custom on the hillside edges, some 1990s infill. Lot sizes often exceed 10,000 sqft. Median sits around $1.1M.
Schools: Saranap is split across Lamorinda and Walnut Creek district boundaries — I pull the exact assignment for every address because it matters a lot here.
The tradeoff with Saranap: you're not technically inside either city's services, so police response and some utilities go through Contra Costa County. Most buyers don't notice, but it's worth knowing.
