I sure you arent being serious, but farday caging the rooms would likely be highly illegal, blocking emergency cell calls and other emergency signals (like radio and gps) is a big ol no no.
Faraday cages are fine. It's just never worth the expense.
It's frequency jammers and active blockers which break the law in a massive way.
The reason being you can control the area a Faraday cage encapsulates. A signal jammer that has any decent effect has to also affect outside the area. Big no
Plenty of buildings are accidentally faraday cages for certain frequencies.
Emergency services have training for buildings with poor signals and it's as simple as putting repeaters down as you progress from outside to inside.
Jammers are much less simple to work around.
This is 100% false
It's a bad idea for the reasons you mentioned, but it's not illegal in the slightest
The Cliff House in San Francisco is a Faraday cage. Phones in the restaurant get no signal. They're completely legal in the United States.
