It's crucial to give your preferred ADU construction type some thought. Between stick-built ADUs, studio sheds, and prefabricated ADUs, you should make a thoughtful decision. 

Make sure you are aware of the differences between each of these unit kinds and that the builder you choose for a prefabricated ADU in the Bay Area can create the type of ADU you want. 

3. Consider the Costs

Your prefabricated ADU in the Bay Area budget should also be considered when choosing a builder. There are different prices associated with the sort of prefab ADU you build, but there are also other factors that may raise the price for a prefab ADU in the Bay Area.
