Small homes can feel incredible when designed well. The best ADUs focus on:

By Cali Dream Construction | January 09, 2026 | San Diego

• Natural light: windows placed for brightness without sacrificing privacy

• Storage: closets, built-ins, and kitchen cabinetry that prevent clutter

• A real kitchen: enough counter space, smart appliance placement

• Bathroom efficiency: good layout, durable finishes, easy ventilation

• Sound control: insulation choices, window quality, thoughtful separation from the main home

• Outdoor connection: a small patio, landing zone, or defined entry

Layout ideas that work well

Studio ADU: Great for rental efficiency and simpler construction. Use furniture and built-ins to define “zones.”

One-bedroom ADU: More comfortable for longer-term living and often better for renters. Make sure the bedroom has real storage and the living area does not feel cramped.

Two-bedroom ADU: Higher build cost but can unlock more flexibility for families and rental income.

Design moves that make an ADU feel larger

• Open living/kitchen area with clear circulation

• Taller ceilings where possible

• Large sliding door to a small outdoor space

• Light, warm materials and layered lighting

• A defined entry that does not walk directly into the kitchen

Strong foundations start with good planning: access, utilities, and scope alignment.
