How to Choose a Sofa for an ADU

An ADU often has compact doors and multipurpose rooms. Prioritize a manageable footprint, simple delivery, and a sofa that does not make the small living zone feel permanent and crowded. Start with the way the room is actually used, then work backward to the specifications that support that use. A good rule here is to separate what you can measure from what you can only learn by using the sofa.

Start with movement

An ADU often has compact doors and multipurpose rooms. Prioritize a manageable footprint, simple delivery, and a sofa that does not make the small living zone feel permanent and crowded.

Measure the full footprint

• Coffee-table or desk clearance — Test standing, chair pull-back, and normal reach instead of relying on a floor-plan screenshot.
• Window, vent, and heater access — Keep operating windows, HVAC, and heat-source clearances usable.
• Delivery route into the room — A sofa that fits the wall still has to reach that wall.
• Finished width and depth — Tape the complete footprint, not just the seat width.
• Main walking path — Protect the route people use repeatedly rather than an unused decorative gap.

Test it with tape

Hidden conflicts

• Forgetting door swings and pathways.
• Planning the room from a wide-angle listing photo.
• Measuring only wall width.

The layout rule

• The main walking route stays comfortable
• The sofa earns the floor space it uses
• Doors, vents, and other furniture still work
