Prefab DADU Tiny Home in Santa Monica: Sung's $1,600 Story

The Essentialist’s Home: Inside Sung’s Legal Prefab DADU in Santa Monica

A $4,500-a-month New York apartment. A change of values. And a tiny prefab home in Santa Monica that proves less really can do more.

Sung is a multidisciplinary designer and entrepreneur who spent years living bicoastally between New York and California, paying $4,500 a month for a one-bedroom apartment that wasn’t even that big. When the time came to realign with her values, simplify her life, and plant roots in one place, she made a decision that most people in her position wouldn’t consider: she went tiny. Not as a novelty or a compromise but as a deliberate, design-forward choice that has given her more presence, more freedom, and more intention than any apartment ever did.

A Legal Tiny Home in One of America’s Most Expensive Cities

One of the most remarkable things about Sung’s home isn’t its design; it’s its legitimacy. The home is a Detached Additional Dwelling Unit, or DADU, a legal housing classification that allows for a fully permitted, self-contained dwelling to exist on a residential property separate from the primary home. In a city like Santa Monica, where housing costs are notoriously out of reach for most people, the DADU model represents a rare and genuinely accessible path to legal, comfortable, and stylish urban living. Sung rents her DADU for $1,600 a month, all in, including all utilities. A figure that is almost incomprehensibly affordable for one of the most desirable zip codes in the United States, and a fraction of what she was paying in New York. It goes without saying that this price is still potentially out of reach for some people, but keep in mind that location is everything.

Built for Efficiency From the Outside In

The home is a prefab structure clad in fiber cement panels on the exterior. These panels are fully weatherproof, highly durable, and play a key role in regulating the internal temperature of the home, keeping it energy efficient year-round without heavy reliance on heating or cooling systems. The same fiber cement panels line the shower, pulling double duty as a design feature and a practical waterproof surface. A recycled rubber base on the bathroom sink adds another thoughtful sustainable detail.

Designed Down to the Last Detail

Sung is a designer by trade, and it shows. Every inch of the home has been intentionally curated. The open closet features a matte black expandable hanging rack with matching hangers (chosen deliberately because it’s open and visible). The bathroom storage uses a combination of soft pouches and hard wire baskets, each sized and selected to fit the exact space available. Wardrobe items under the bed are rolled, categorized, and stored in pouches for instant visibility. The pantry holds only what’s needed and never more. A remote-controlled lighting system in the bedroom adjusts from reading light to wind-down ambiance without getting out of bed.

The kitchenette features a Corian countertop that can handle hot pots directly, a practical choice for a small surface that works hard. Rather than cramming in a cooktop, Sung cooks outside on a double-burner propane setup, a decision she credits with making her more efficient in how she preps and plans meals. A mini fridge, a right-sized sink, and a well-organized pantry cabinet complete a kitchen that is small but never limiting.

Outdoor Space as an Extension of Home

The outdoor garden area is a genuine sanctuary — jasmine, lavender, self-watering plants, a café table, and a lounger that doubles as a reading and break spot. For someone coming from a New York apartment with no outdoor space at all, having even a small private garden close to the ocean in Santa Monica felt like a luxury. Sung designed it with the same intentionality as the interior — small features that function well and genuinely get used every day.

The Freedom That Comes From Less

Sung’s story is ultimately about what happens when a designer applies her skills not to a large space, but to a life. Living in a DADU in Santa Monica has made her more present, more deliberate, and more free. Not despite the constraints of a tiny home, but because of them.

“That discipline has actually given me a lot more freedom,” she says. In a city where most people feel priced out and stretched thin, Sung has found a legal, beautiful, and deeply considered way to live well for $1,600 a month, all in.
