Prices for modular homes in California

[Galina Milman]

Hi guys. What modular home company do you use and what price do you pay per sq foot (with and without installation) in California or free delivery to CA? I am trying to install an ADU unit in my backyard ( half acre) and looking for affordable options or any other creative ideas from you. The companies that offer this cervices here are total sharks and charge $250-$350 per sq ft (including permits and labor). I am trying to be creative and see if I can buy a modular home 600-700 sq ft and pay separately for permits and labor. We are located in East Bay (40 miles from San Francisco)
