House Plans with Mother-in-Law Suites

Our barndominium floor plans with in-law suites are designed to meet the growing demand for multigenerational living and aging in place.

36″ ADA-compliant doors are used throughout the separate living space, and thought was put into offering easy access for walkers and wheelchairs in halls and bathrooms.

All our in-law Suites Offer

• ADA Compliant Living Space
• Single Story – ground level access
• Private Entrance
• Garage Space for In-law Suite
• Separate Laundry
• Privacy with noise barriers
• Separate HVAC zones

These thoughtfully designed homes offer flexible layouts that support family members of all ages, whether you’re caring for an aging parent, accommodating an adult child, or planning for your own future needs.

Each plan in this category features a private in-law suite—sometimes called a granny flat, guest apartment, or secondary dwelling unit with its own bedroom, bathroom, and often a full kitchen, laundry, and living area.

These suites are ideal for promoting independence while keeping loved ones close. Many include private entrances, separate HVAC zones, and direct access to outdoor living spaces, making them ideal for long-term family use or future rental income.

All of our in-law suite Barndominium plans are fully customizable and can be built using your preferred kit type, including Red Iron Steel, SIPs, or Cold-Formed Steel. They are engineered to meet your local building codes and come with stamped plans, ready to build.
