ADU or room addition? How to think through the choice

Start with why you want more space

Rentals, family, work-from-home and long-term flexibility each point to different solutions. A detached ADU might be ideal for long-term guests or rental, while an addition may be better if you mainly want more room for the people already in the house.

Think about separation and privacy

ADUs shine when you want a clear separation between spaces. Additions shine when you want everything to feel more connected. There is no single right answer – just a better fit for your goal.

Look at your lot and budget honestly

Setbacks, slopes, access and utility locations will all influence what is realistic. So will your budget and how much disruption you are comfortable with during construction.
