A lot of these do not affect homeowners but a few might bite you. One
is a change to 680.4 that allows AHJs to do periodic inspections of
existing pools. I am not sure what the exact language is but this has
always been true of public pools. They are also going to start
requiring an outside disconnect at a dwelling. That would also affect
panel swap outs but it is probably not retroactive.
