If my memory is correct, Boston has banned masks.
This anti gun, anti vest and other laws are just stupid. What defines a criminal is that they break laws, which means they will break whatever law it takes to have a gun or a vest or a mask. Breaking a law is their business.
What those stupid laws do is prevent law abiding citizens from defending themselves and being safe.

California compelled the wearing of masks in post offices even after compulsory mask-wearing was discontinued at the federal level.
so... the question could be asked, who has jurisdiction in federal buildings such as post offices? or is jurisdiction a function of the particular legal domain to which a given law relates?
