Planning Your ADU Layout: Maximizing Space and Functionality

When converting your garage into an ADU, thoughtful layout planning is essential for creating a functional and comfortable living space. The right design can transform even a modest garage into a highly efficient home.

Key Layout Considerations

Open Concept vs. Defined Spaces Open floor plans work well for smaller garages (under 400 sq ft), while larger spaces can accommodate separate rooms for privacy and functionality.

Kitchen Placement Position the kitchen along exterior walls for easier plumbing and ventilation access. Consider galley or L-shaped layouts for efficient use of space.

Bathroom Location Place bathrooms near existing plumbing lines when possible to reduce conversion costs. Corner locations often work well for space efficiency.

Maximizing Square Footage

Vertical Storage Solutions Use wall-mounted cabinets, floating shelves, and tall storage units to maximize floor space while providing ample storage.

Multi-Functional Furniture Incorporate furniture that serves multiple purposes: dining tables that double as work spaces, beds with built-in storage, and foldable elements.

Natural Light Optimization Strategic window placement and skylights can make spaces feel larger and more inviting while reducing energy costs.

Common Layout Mistakes to Avoid

• Insufficient storage planning
• Poor traffic flow patterns
• Inadequate natural lighting
• Ignoring building code requirements
• Overlooking accessibility considerations

A well-planned layout ensures your ADU meets both current needs and future flexibility requirements while maximizing your investment return.
