Start with the ADU's footprint and type — a detached backyard cottage, a garage conversion, or an attached in-law suite — then list the rooms: bedrooms, bathroom, kitchen or kitchenette, and living area. You get a to-scale 2D plan to review before you talk to a designer or check local ADU rules.

How to make an ADU floor plan

  1. Give the size

    Enter the overall size of the ADU in feet or metres, for example 20 × 30 ft (600 sq ft).

  2. Describe what goes inside

    List the living area, kitchen, bedroom, bathroom, laundry, and entry or porch. Add sizes or counts where you know them.

  3. Place doors and windows

    Say which walls get the entrance, doors, and windows, and which way the doors swing, so the ADU floor plan shows real clearances.

  4. Check and download

    Review the spacing and walkways, change the description if something does not fit, then download the ADU floor plan as SVG or PNG.

Planning an ADU (accessory dwelling unit)

Most ADUs are between about 400 and 1,200 sq ft, and the size, height, and setbacks allowed depend on your city or county, so check local rules before settling on a footprint. Inside a small ADU, an open kitchen and living room usually makes the space feel larger than separate rooms.

Describe the ADU in plain English and you get a clean, to-scale 2D ADU floor plan with walls, doors, windows, and furniture. It is a planning drawing to test ideas and share with others, not a construction document.

Frequently asked questions

Can I plan a garage-conversion ADU?

Yes. Give the garage size and say where the existing garage door and walls are, then describe the rooms you want inside.

Is the ADU floor plan drawn to scale?

Yes. Every ADU floor plan is drawn to scale in the units you type, so you can measure walkways and clearances.

Can I edit the ADU floor plan after it is generated?

Yes. Change the description, for example a size or a room, and generate again. Each version is a new to-scale plan.

Is the ADU floor plan a construction drawing?

No. It is a 2D planning layout for sizes, furniture, and flow. Use an architect, builder, or licensed trade for construction and permit drawings.

Is the ADU floor plan maker free?

Yes, with no signup. Generation has hourly fair-use limits, and you can download SVG or PNG.
