Something I noticed happening around Boston metro starting with the pandemic is there is a lot more new builds than additions and remodels. The remodel we tried to do ended up significantly delayed due to labor and other shortages, and shopping around was very difficult. It made me wonder whether the developers prefer the hassle-free experience of unoccupied or new builds where you don't have constant headaches of finding old out-of-code shit, having to design custom workarounds, back and forth with the owners, keep the existing structure protected from elements, etc. I can imagine if the work is very asynchronous it would add hidden costs as well due to inefficiency.
