Detached vs. Attached ADU in 2026: Which One Fits Your Lot (and Budget)?
Both Detached ADUs and Attached ADUs can be great—your lot, access, and utility paths usually determine the best fit.
Why This Matters for ADU Projects
Most homeowners want fewer revisions, faster approvals, and a smoother build. That’s why we align ADU Design, ADU permitting, and ADU construction from the start.
1. When Detached ADUs Make Sense
Detached units can offer better privacy and rental appeal, but often require longer utility runs and more site work.
2. When Attached ADUs Win
Attached ADUs can reduce utility complexity and construction scope, especially when the addition is designed efficiently.

FAQs
Which type rents better?
Often Detached ADUs due to privacy, but location, layout, and finish quality matter more than type alone.

It depends—site constraints and completeness of the plan set often drive speed more than type.
