What are you building costs for ADU's?

[Brad S.]

Hey everyone!

This is mainly for those who have recently built or got contractor/builder quotes for building an ADU. I am curious as to what your are finding the current building costs are?

I am working on putting together a building system to be around $150/sf hard costs for a build. The idea is to systemize the process and be able to offer a good quality product for a lower price than is generally available, and still make a decent profit. And we would start with building ADU's, since that seems readily systemizable and a popular trend with good demand.

So, does $150/sf sound attractive to you if you were in the market to build an ADU? between 800sf-1,200sf

I am mostly looking for California opinions, but all are welcome. TIA
