1620 California Avenue is a rare offering North of Wilshire, where architectural character, coastal living, and investment potential come together in one of Santa Monica’s most coveted settings. An original Spanish Revival duplex, the property possesses the kind of character that cannot be recreated. Its architecture reflects the craftsmanship, proportions, and romance of another era, while its duplex configuration creates an uncommon level of flexibility for today’s buyer. Live in one residence and lease the other, restore the property into a distinctive architectural compound, or hold it as a long term investment in one of Santa Monica’s most enduring neighborhoods. Beyond the property itself, the location is truly exceptional. Montana Avenue, Palisades Park, the Pacific Ocean, Third Street Promenade, celebrated restaurants, boutique shopping, and the best of Santa Monica are all just moments away. This is a neighborhood defined not only by its desirability, but by its scarcity. For the buyer who values authenticity over the ordinary, 1620 California Avenue offers something increasingly difficult to find: an original piece of Santa Monica with the flexibility to shape its future. Whether restored as a remarkable Spanish Revival residence, enjoyed as an owner user duplex, or held as a premier coastal investment, the opportunity is as much about what already exists as it is about what can be created. Architectural heritage. Coveted location. Exceptional flexibility. A property with a story worth continuing.
