Detached ADU vs. Attached ADU: Which is Best for You?

Deciding whether to build a detached or attached Accessory Dwelling Unit (ADU) can significantly impact your property. Here’s a brief guide to help you choose the right option.


Detached ADUs

Advantages:

  • Privacy: Offers more privacy for both the main house and ADU occupants.

  • Versatility: Ideal for rentals, guest houses, home offices, or studios.

  • Higher Rent: Often commands higher rental rates due to increased privacy.


Considerations:

  • Space: Requires more land, suitable for larger lots.

  • Cost: Typically higher due to separate foundations and utilities.


Attached ADUs

Advantages:

  • Cost-Effective: Generally less expensive, utilizing existing structures and utilities.

  • Permitting: Easier and faster permitting process.

  • Accessibility: Great for family members or caregivers needing proximity.


Considerations:

  • Privacy: Less privacy due to shared walls.

  • Design: Must integrate with the existing home, limiting customization.


Comparison

  1. Cost: Detached units are more expensive; attached units are cheaper.

  2. Privacy: Detached units offer more privacy; attached units offer less.

  3. Space: Detached units need more space; attached units fit smaller lots.
