Sketch an ADU.
An ADU is a small extra home on a lot that already has a house. Pick a type, set a size up to 900 square feet, then drag the rooms. No account. No name.
Concept only, not for permits or construction.
30 ft wide × 20 ft deep · 600 sq ft
Drag a room to move it. Drag the amber corner to resize it. Arrow keys move the selected room. Shift plus an arrow resizes it. Every edge snaps to a 1-foot square.
Rooms add up to 600 sq ft. The rooms fill the ADU.
This page does not save a sketch and does not look up an address. A share link holds the drawing in the link itself. To see if a real lot can hold an ADU, open the ADU feasibility checker.
