Retrofitting small multifamily communities with smart locks

I'm interested in understanding what the requirements are to change out tenant locks and some common locks (gym/laundry) from traditional keyed locks to smart locks? This would be to update existing older properties, no wiring would be needed. I'm curious about information across the US, not just in one specific location.

Are permits required?
Is this now and access control situation?
Can handymen do the work?
What geographies are interconnected locks required for the tenant doors?
