Accessory Dwelling Units (ADUs) are one of the smartest ways to add value, create rental income, or house family members in comfort. Whether you’re considering a backyard ADU, a garage conversion to ADU, or a custom build, the right floor plan makes all the difference. At EDR Design Build, our team specializes in ADU design and construction tailored to the needs of Bay Area homeowners.

Here are 5 stylish ADU floor plans to inspire your project.

1. The Compact Studio

Perfect for maximizing small spaces, a studio ADU house features an open layout with combined living, dining, and sleeping areas. By incorporating smart storage and a compact kitchenette, these designs make ideal guest suites or affordable rental units.

2. One-Bedroom with Open Living

Among the most popular ADU floor plans, a one-bedroom design separates private sleeping space from an open-concept living area. Sliding glass doors to a patio or backyard extension can make even a smaller backyard ADU feel spacious and inviting.

3. Garage Conversion Retreat

Transforming a garage into an accessory dwelling unit is one of the most cost-effective ways to add livable space. With careful planning, a two-car garage can accommodate a full one-bedroom ADU layout complete with kitchen, bath, and private entry.

4. Two-Bedroom Family ADU

For multigenerational living or maximizing ADU rental income, a two-bedroom floor plan offers flexibility. Whether used for extended family, tenants, or a combination of both, this option provides privacy while still fitting on most Bay Area lots.

5. Loft-Style ADU with High Ceilings

A loft-inspired ADU design brings modern flair to small footprints. High ceilings, mezzanine sleeping areas, and open kitchens create a spacious feel that attracts renters and buyers alike. This style is especially popular with younger tenants looking for modern, efficient living.

Why Floor Plans Matter for ADUs

The success of an ADU often depends on how well the space is designed. A thoughtful layout ensures the unit is functional, stylish, and compliant with California ADU regulations. From rental opportunities to housing loved ones, the right floor plan sets your ADU up for success.
