Rare opportunity to acquire a large, flat residential lot in an established Ontario neighborhood surrounded by classic California bungalow homes and pride of ownership. Spanning approximately 9,900+ square feet, this rectangular parcel offers an exceptional canvas for builders, investors, or owner-users looking to create a custom residence tailored to their vision.
