5 Ways to Maximize a Small ADU Floor Plan

Building a small ADU (Accessory Dwelling Unit) doesn’t mean sacrificing comfort or function. With innovative design strategies, you can create a beautiful, livable space that feels open, bright, and efficient, no matter the square footage.

Here are 5 expert-approved ways to make the most out of your small ADU floor plan:

1. Open Concept Living

Walls eat up space. Open layouts allow your kitchen, living, and dining areas to flow together, making the entire ADU feel larger and more welcoming. Consider a peninsula or island to divide the kitchen without closing off space.

2. Use Built-In Storage

Think vertically! Floor-to-ceiling shelves, under-bed drawers, built-in benches with storage—these all help you reduce clutter while saving square footage. In small ADUs, every inch matters.

3. Let the Light In

Natural light is one of the easiest ways to make a small space feel bigger. Include large windows, skylights, and glass doors wherever possible. Lighter paint colors on walls and ceilings also help reflect light, creating an airy atmosphere.

4. Multi-Functional Furniture

Look for pieces that can serve double duty: a Murphy bed with a fold-down desk, a sofa bed, or a dining table that extends. These smart swaps enable your ADU to adapt to various uses, including guests, work-from-home, or rental income.

5. Minimize Hallways

Hallways occupy valuable square footage but don’t provide livable space. A well-designed ADU floor plan maintains tight and functional circulation, with direct connections between living spaces, bedrooms, and bathrooms.
