This 2 bedroom 2 bath ADU plan is a single-story detached unit with 900 sq ft of living space on a 28'-10" × 34'-1" footprint. The main living area combines a 10'-8" × 15'-7" living room, a 9'-8" × 8'-8" dining area and a 9'-8" × 12'-5" kitchen with an island, so cooking, eating and sitting share one open space. A covered porch extends the living area outdoors.
The 11'-5" × 5'-6" hall connects the shared rooms to the sleeping areas. Bedroom 1 measures 10'-1" × 10'-4" and has a 7'-0" × 5'-5" ensuite bath. Bedroom 2 measures 9'-0" × 10'-4" and is served by a 5'-1" × 7'-8" bath. A 7'-0" × 4'-6" laundry closet keeps the washer and dryer out of the main rooms. Because each bedroom has its own bath, the plan works well for two separate occupants.

Who this plan suits
This plan suits homeowners who want a rental, guest or family unit where two occupants each get a private bath. It needs a backyard lot that can fit a 28'-10" × 34'-1" footprint plus setbacks.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Detached backyard ADU: 2 bedrooms each with its own bath (one ensuite), open kitchen with island, dining and living, laundry closet, covered porch, about 880 sq ft of living space.” 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 2 bedroom 2 bath ADU plans?
They are plans for an accessory dwelling unit with two bedrooms and two bathrooms, usually built behind or beside a main house. This version is a one-story detached unit with 900 sq ft of living space, an open kitchen and living area, and a laundry closet.
What affects the lot fit and cost of building this ADU?
The 28'-10" × 34'-1" footprint must fit within your local setbacks, and utility connections, foundation type and finish level all influence cost. Your local ADU rules on size, height and separation from the main house also apply, so check them before you start.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as moving rooms, resizing a bedroom, or adjusting the footprint for a narrower or wider lot. The plan is then updated and the drawings are regenerated. This plan has no garage, so the garage side does not apply here.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing the layout and sharing it with contractors or a permit office. The DXF opens in CAD software for drafting and site plans, and the IFC imports into BIM tools for coordination. Local permits usually require review by a licensed professional.
