Tucked along one of Hermosa Beach’s most cherished walk-streets, 42 21st Street is a rare gem—a perfect blend of classic beach bungalow charm and timeless California retreat. Where front patios double as outdoor living rooms and the ocean is just steps from your door, this is the kind of home that rarely comes up and never lasts long. Inside, vintage character shines through beamed ceilings, brick accents, and warm wood floors. The open living area flows seamlessly into a bright kitchen featuring bar seating and classic coastal touches, while natural light pours in from every angle. The home currently lives as two separate units: the front house opens up to a sunny walk-street patio and features 3 bedrooms and 2 baths, including a primary suite with its own bath. Through another charming brick patio, the back unit is a cozy 1-bedroom, 1-bath with an open layout downstairs and a large deck off the bedroom, offering multiple options for indoor and outdoor living. Legally zoned for three units but comfortably living as two, this property presents exciting possibilities for the next owner. This is Hermosa Beach at its best: walkable, welcoming, and alive with community spirit. Whether you’re seeking a soulful beach escape or a smart long-term investment in one of Southern California’s most coveted neighborhoods, 42 21st Street offers a front-row seat to the beach lifestyle you’ve always dreamed of.
