adu with garage plans — dimensioned floor plan

This detached ADU is a single-level plan with 610 square feet of living space, not counting the garage. The footprint measures 31'-10" × 27'-11". A covered entry opens into the main living area, where the 10'-8" × 14'-3" living room sits beside a 10'-8" × 7'-4" kitchen, so cooking and sitting share one open space.

An 11'-5" × 3'-7" hall leads to the private rooms: a 7'-0" × 13'-11" bedroom with a 7'-0" × 5'-1" closet, a 6'-6" × 7'-4" bathroom, and a 4'-6" × 7'-4" laundry. The 10'-8" × 18'-2" one-car garage is attached and shares the same 10'-8" width as the kitchen and living room, which keeps the footprint compact. With one bedroom and one bath, the plan works as a guest suite, rental, or a home for a family member.

Who this plan suits

This plan suits homeowners who want a compact rental, guest house, or in-law unit with its own parking. It needs a lot that can fit a 31'-10" × 27'-11" footprint plus the setbacks your local code requires.

How this plan was made

It was generated in AI Architectures Plan Studio from this one-line brief: “Detached ADU with an attached 1-car garage: 1 bedroom, 1 bath, open kitchen and living, laundry, covered entry, about 600 sq ft of living space (garage not included).” An AI architect drafted the room program, a layout solver placed every wall and door, and the plan was checked automatically for room sizes, circulation and daylight. The same project produced the PDF sheets, layered DXF, IFC model and 3D model you can download above.

Frequently asked questions

What are ADU with garage plans?

ADU with garage plans describe an accessory dwelling unit that includes a parking space as part of the same building. This version is a detached 1-bedroom, 1-bath home with 610 sq ft of living space and an attached 1-car garage. The garage is not counted in the living area.

What affects the lot and cost of building this ADU?

The 31'-10" × 27'-11" footprint sets the minimum lot area, and local setbacks, ADU size limits, and driveway access decide whether it fits. Cost depends mainly on your region, foundation type, finishes, and utility connections to the main property. Check local ADU rules before you commit to a site.

Can I change this plan by chat?

Yes. You can describe changes in chat, such as moving the garage to the other side, resizing rooms, or adjusting the plan to suit a narrower or wider lot. The layout is then updated to reflect your request.

How do I use the PDF, DXF, and IFC files?

The PDF is for reviewing the plan and sharing it with contractors or your permit office. The DXF opens in CAD software for editing and drafting. The IFC is a BIM format that you can import into compatible modeling tools to check the 3D layout.
