Rare Newport Beach duplex opportunity at 213 33rd Street, just steps from the sand on the Balboa Peninsula. Built in 1953 with the upstairs unit added in 1960, this property has been owned by the same family since it was originally constructed. The duplex features two units, each with two bedrooms and one bathroom in very similar floor plans, providing a versatile layout ideal for investors or owner-occupants looking to offset their mortgage with rental income. The downstairs unit measures approximately 737 square feet and is a standalone space with no shared walls with the upper unit, offering a true sense of privacy along with a roughly 203 square foot patio with convenient sidewalk access. The upstairs unit is approximately 616 square feet, sits above the large garage, and features a spacious 254 square foot front deck with elevated views and natural light. Both units have copper plumbing and the underground sewer line has been relined. Both units will be delivered vacant at close of escrow, giving the buyer a clean slate to execute their vision from day one. The property carries a long history of rental income, and the units are clean and show well. A buyer can rent immediately to generate income while planning a future renovation, fully renovate both units to command premium rents in one of the most desirable coastal markets in Southern California, or even explore converting the property to a single-family residence. The oversized 565 square foot two-car garage includes laundry hookups, and additional off-street parking accommodates a full-size SUV in front of the garage door in the alley. What truly sets this property apart is the location. The Balboa Peninsula is one of the most vibrant and walkable communities in Orange County, where residents can stroll to the beach, grocery stores, shopping, restaurants, and entertainment without ever needing a car. This is a lifestyle location with year-round appeal that drives consistent tenant demand and long-term value appreciation. Properties like this rarely come to market, and the combination of a flexible floor plan, vacant delivery, and an unbeatable walkable coastal setting make this duplex an exceptional opportunity for the buyer ready to put their stamp on a prime piece of Newport Beach real estate.
