Seeking ADU Advice
I am thinking of adding a small (400 sq feet) freestanding prefab ADU. I would hugely appreciate contact info on any companies that you can recommend as well as those to avoid. If there were issues that you wished you knew about in advance of purchasing an ADU, I would love to hear about them as well. Thanks so much.

To avoid: I STRONGLY suggest avoiding Valley Home Development (AKA PrefabADU), based in Fairfield. Read their Google or Yelp reviews, and stay far, far away. Good luck!
