DETACHED ADU SOLUTIONS for BUILDERS and OWNER-BUILDERS

Our plans are easy to customize for local conditions.

WHAT IS A DETACHED ADU?

A detached ADU: also called a backyard cottage or granny flat: is a small, self-contained home located on the same lot as your main residence. It has its own entrance, kitchen, bathroom, and living space. This allows someone to live independently while still staying close to home.

Detached ADUs are becoming one of the most popular ways to add flexible living space in the United States.

DETACHED ADU VS ATTACHED ADU

Detached ADU

A completely separate building. Ideal for privacy, rentals, and independent living. Detached ADUs feel like a true second home.

Attached ADU

An addition with its own entry, kitchen and bathroom connected to the main home structure. Attached ADUs benefit those with smaller backyards.

Both types of accessory dwelling units create valuable additional housing.

Privacy For Everyone

ZONING, PERMITS, AND REQUIREMENTS

Local zoning laws define size, placement, and allowed ADU types. Many U.S. cities now support ADUs to expand housing options.

Key factors include:
• Size limits: often 200 to 1,000 sq ft
• Setbacks and lot coverage
• Parking rules
• Utility connections
• Permit approval timeline

Efficient permitting and predictable project planning create a smoother building experience.

COST AND FLOOR PLAN OPTIONS

Building costs vary by design, finishes, and location. Many detached ADUs range from $150,000 to $400,000+.

Costs include:
• Architectural design
• Permits and city fees
• Materials and labor
• Equipment rental
• Utility connections

Choose from studio layouts, one-bedroom, or two-bedroom designs. Customize your space to match your lifestyle
