The municipality is on their side because they're overworked.

In even the smallest town, if any appreciable percentage of new builds required custom handling... the system would instantly be person-starved and start backing up.

Business-as-usual is the fast/efficient path from a paperwork standpoint. Anything odd is (a) discouraged and (b) looked at with annoyance because it takes more time.

One reason it's almost always cheaper to tear-down fire damaged houses with still viable framing. No one wants to take the time to quantify exactly how much the framing was damaged.
