Exceptional development opportunity in a desirable Castro Valley location surrounded by newly built multimillion-dollar homes! This approximately ½-acre+ vacant parcel offers an exciting opportunity for a builder, investor, or future homeowner. The property features beautiful Bay and valley views and may have the potential to be subdivided into as many as three separate lots. Drawings and site plans for three homes are available, and utilities have already been brought to the lot line. With impressive newer homes being built throughout this small development, the property offers multiple possibilities—build a spectacular custom home on a large lot or explore subdividing the parcel and developing multiple residences. Conveniently located near freeway access, shopping, schools, restaurants, and other amenities, while offering the space, views, and residential setting that make the Castro Valley hills so desirable. A rare opportunity to acquire approximately half an acre in an area experiencing significant new-home investment and development. Buyer to investigate and verify subdivision potential, zoning, allowable density, utilities, building requirements, and all development possibilities with the appropriate agencies.

ZIP averages use publicly displayable closed sales from our licensed MLS feed, matched to the same ZIP and exact property type. Months with fewer than 3 sales are omitted; the current month is incomplete. Lines connect available monthly observations across gaps and do not represent measured prices in missing months. These averages are not adjusted for size, condition, or location within the ZIP, and are not an appraisal. Feed coverage may not include every sale. All available shows the available home and ZIP history, with mortgage rates over the same dates.
