Maximize Your Space

1 bedroom ADU floor plan sizes

1-bedroom ADUs are versatile, functional, and efficient. Their size, design, and customization options make them an excellent choice for maximizing your property’s value and functionality while aligning with your lifestyle.

1-bedroom ADUs range from compact layouts to California’s 1200 sq. ft. max (or 1000 sq. ft. in some San Diego areas). Your lot size and how you’ll use the ADU—full-time housing or a guest space—will guide your choice.

Smaller ADUs can feel spacious with smart layouts. Open designs, multi-functional spaces, and clever storage make every square foot count.

Design your ADU around your needs. Bigger bedrooms, functional kitchens, or in-unit laundry—focus on what adds value and comfort to your space.

A 1-bedroom ADU gives more privacy than a studio. Thoughtful designs—like fencing, landscaping, and smart window placement—keep it comfortable for everyone.

Your lot’s size and shape are key to your ADU design. Maximize space while meeting setback rules, like California’s 4-foot requirement. Position the unit for privacy and natural light.

Finding the right balance between cost and functionality is key. Focus your budget on essentials like a comfortable bedroom and efficient kitchen, and consider cost-effective upgrades that make a big impact, like durable materials or energy-efficient fixtures.

1 Bedroom ADU Plans

Why choose a one-bedroom ADU floor plan?

A 1-bedroom ADU strikes the perfect balance of privacy, functionality, and added value, making it an excellent upgrade over a studio apartment. With separate living and sleeping areas, it provides more comfort, flexibility, and income potential—all while staying budget-friendly.

Better in-law suite

Loved ones get privacy & comfort while staying close.

Boost rental income

Higher rents & better returns.

Launchpad for adult kids

Ideal for grown kids gaining independence.

Private retreat

A detached ADU offers a quiet space for work or relaxation.

Adds property value

Increase your home’s worth and appeal.

Smart investment

A versatile unit that strengthens your portfolio.

Custom vs. pre-approved plans

Built around your needs

Custom plans for 1-bedroom ADUs let you design the perfect space. Want a larger bedroom, a full kitchen, or smart storage? Customize your layout to fit your lifestyle and make every square foot count.

Long-term value

While pre-approved plans are quicker and more affordable upfront, custom designs can increase your property value and deliver better functionality—especially for compact 1-bedroom layouts where thoughtful design matters most.

Lot-friendly and compliant

Custom plans are tailored to your lot’s unique dimensions and comply with local zoning rules, including California’s 4-foot setback requirements. This ensures a smooth permitting process and a layout that fits seamlessly on your property.

A tip from our designer...

decorative

Sarah

Interior Designer
"When designing your ADU, opt for open floor plans, high ceilings, and compact kitchens to maximize the sense of spaciousness and functionality within your available footprint. Remember, the ideal size and placement of your ADU will depend heavily on your lot dimensions and local zoning regulations. To create a sense of privacy and separation, consider strategic fencing and landscaping that blends seamlessly with your property's aesthetic. Lastly, incorporate large windows, skylights, and glass doors to flood your space with natural sunlight, enhancing the overall comfort and visual appeal of your ADU."

Common layouts for 1-bedroom ADUs

1-bedroom ADUs are versatile and efficient designs that work for small lots, rental spaces, or private retreats. Below are some popular layouts that can suit a variety of lot sizes and lifestyles.

For homeowners with larger lots, a 1000-square-foot ADU layout feels like a true home. It features a spacious bedroom with room for a sitting area, a full-sized kitchen, a large living room, and even a separate office nook. This is perfect for those looking to create a luxurious private retreat.

This compact 400-square-foot layout is ideal for smaller lots or those seeking minimalistic living. It features an open-concept living area with a combined kitchen and dining space, a cozy bedroom, and a full bathroom. Smart storage solutions like built-in shelves and multifunctional furniture can make the most of the space.

Measuring just 440 square feet, this one bedroom ADU floor plan balances privacy and functionality. The bedroom offers space for a queen bed and built-in closet, while the open kitchen and living area flow seamlessly together. This design works well for guest houses or short-term rentals.

A 500-square-foot design offers a slightly larger layout, making room for additional amenities like a small dining nook or in-unit laundry. The kitchen provides ample counter space, and the bedroom includes a built-in wardrobe for storage.

With a more spacious feel, this ADU provides a 623-square-foot one-bed, one-bath layout that is perfect for full-time living. It includes a larger kitchen with space for full-sized appliances, a generous bedroom, and a private patio for outdoor living.

A 750-square-foot plan is ideal for those who want more comfort and flexibility. It includes room for a dedicated dining area, a walk-in closet in the bedroom, and plenty of living space. This layout is often chosen for long-term rentals or multigenerational living.
