A rare opportunity to own a true Spanish Colonial estate in the heart of Hayward. Set on nearly three-quarters of an acre, this 3-bedroom, 2-bath residence offers approximately 3,488 sq. ft. of living space with timeless architectural character and exceptional privacy. Tucked away at the corner of historic Prospect Street, long regarded as “the Mayor’s Street” for its lineage of Hayward mayors and dignitaries, this estate sits beyond a private road that offers a quiet and secluded escape. The setting evokes a sense of retreat while remaining just minutes from downtown Hayward and major commuter routes. Steeped in local history, the property features the first residential swimming pool ever built in Hayward, set against panoramic views that stretch to downtown San Francisco, including the Salesforce Tower and city skyline. The pool deck and mature landscaping create a serene, resort-like ambiance rarely available at this price point. Properties of this caliber are typically found in Hillsborough or the Oakland Hills—yet here, it remains within reach. The expansive lot offers space for entertaining, gardening, or future expansion, appealing equally to those seeking a signature residence or a distinctive investment opportunity.
