Rare triplex opportunity in the heart of Martinez! Live in one and rent the others. Ideal for house hackers or investors, this property features a vacant 3 bedroom / 2 bath upper unit (Unit C) perfect for an owner-occupant, while two tenant-occupied 2 bed / 1 bath units provide immediate income. Each unit has its own entrance and dedicated outdoor space—either a deck or patio—offering privacy and independence for residents. Carport parking and shared laundry access add convenience. The spacious upper unit is ready for move-in or rental, offering a turnkey option for an owner-occupant looking to offset their mortgage. Tucked into a peaceful hillside neighborhood near Hidden Lakes Park, the property is also walkable to Safeway, Starbucks, and local dining, making daily life incredibly convenient. Zoned for Valhalla Elementary, Valley View Middle, and College Park High, it's an ideal setting for long-term value and livability. Commuters will appreciate easy access to Highways 4 & 680, and a short drive to North Concord BART and the Martinez Amtrak station connects you to the entire Bay Area and beyond. Whether you're seeking flexibility, income potential, or a smart investment in a prime location, this triplex checks all the boxes.
