ADU Design | Los Angeles

An ADU kitchen needs to be functional, not just present. Counter space, appliance selection, cabinet depth, and ventilation are all considered within the spatial constraints of the unit. We spec ADU kitchens for actual daily use. In a Junior ADU, an efficiency kitchen with a sink and cooktop satisfies the requirement; in a full ADU, a complete kitchen with refrigerator, range, and adequate workspace is both achievable and worth the investment in rentability.

A full bathroom — toilet, sink, and shower or tub — is required in every standard ADU. The layout is constrained by square footage, but thoughtful fixture selection, tile work, lighting, and storage integration can make a compact bathroom feel resolved and well-made. Waterproofing is handled with the same rigour we bring to primary residence bathrooms — because the consequences of shortcuts here compound quickly, especially in a rental context.

Building code dictates minimum dimensions for habitable sleeping rooms — typically 70 square feet with no dimension less than 7 feet. Beyond compliance, a bedroom in an ADU should feel like a real room: adequate closet space, properly placed windows for natural light and ventilation, and enough clearance to move comfortably. These choices directly affect rental attractiveness and long-term livability.

In smaller ADUs, the living area and kitchen often share a single open space. How that combined area is planned — where the kitchen sits relative to natural light, how traffic flows between entry and bedroom, where outlets and media connections land — determines whether the unit feels spacious and livable or cramped and compromised. Open-plan ADU layouts reward spatial planning far more than they do square footage alone.

A separate entrance is both a legal requirement and a practical necessity for independent living. Its placement matters: it should provide genuine privacy from the primary residence, connect logically to whatever parking or outdoor space the tenant uses, and be designed with safety and visibility in mind. The entry sequence — the path from the street to the ADU door — is often an afterthought in ADU planning, and rarely should be.

Not code-required but consistently among the most valued features in a Los Angeles ADU rental. In-unit laundry dramatically improves the unit's rentability and reduces friction for long-term tenants. Storage — closets, pantry space, exterior storage where possible — follows the same logic. These are the details that separate an ADU that sits on the rental market from one that leases immediately at full asking price.
