Set directly on the sand in one of California’s most desirable coastal locations, this oceanfront triplex offers uninterrupted Pacific and Catalina views, exceptional flexibility, and rare income potential just steps from historic Main Street. Thoughtfully arranged for multiple living or rental possibilities, the property features two main residences plus a newly constructed studio ADU, each offering its own distinct appeal. The upper residence includes 2 bedrooms and 2 baths, highlighted by folding glass doors that open to an expansive ocean-view balcony. The lower residence offers 3 bedrooms and 1 bath, an open living area with inside laundry, and direct access to a generous beachfront deck. Above the garage, the studio ADU features high ceilings, modern finishes, mini-split A/C, and washer/dryer hookups, creating an ideal space for guests, extended family, or additional rental use. With two one-car garages, nearby resident parking privileges available at a reduced rate, and just steps from the Seal Beach Pier, boardwalk, volleyball courts, playground, Main Street dining, shops, cafés, and major freeways, this property delivers the kind of coastal convenience buyers hope for but rarely find. A standout opportunity for owner-users, investors, or those seeking a beachfront retreat with built-in versatility.
