A truly rare opportunity to own one of San Pedro's most recognizable mixed-use properties. Located in the desirable Vista Del Oro neighborhood on a 5,004 SF LARD2-zoned lot, this unique property includes the historic Gray School of Music, established in 1950, along with three residential units tucked privately behind the commercial building. A San Pedro institution for over 75 years, the Gray School of Music has taught generations of musicians, including Eddie and Alex Van Halen. The business is included in the sale and is fully turnkey with an established student base of approximately 85-100 students, experienced instructors willing to remain, recurring tuition income, and significant upside for a new owner. The approximately 1,656 SF commercial building features seven teaching rooms, one restroom, reception area, foyer, display cases, and central heating, providing everything needed to continue operations or expand into recording, music production, or other creative ventures. Behind the school are three residential units totaling approximately 1,479 SF. Two charming 1920s bungalow-style 1-bedroom, 1-bath homes offer timeless character, including one beautifully renovated in 2023. The newly completed ADU (2026) features 1 bedroom, 1.75 baths, laundry hookups, split-system AC, and modern finishes, making it ideal for an owner-user, employee housing, or additional rental income. Separate electric and water meters, shared laundry, private yard areas, four fenced parking spaces with alley access complete the residential setting. Conveniently located across from Leland Elementary School, where the school has traditionally hosted recitals, and just minutes from the rapidly evolving San Pedro Waterfront and West Harbor development, this property offers a rare combination of history, multiple income streams, owner-user flexibility, and long-term investment potential. Financing options are available through lenders experienced with mixed-use and owner-user properties. Call for business details and private showing.
