What are the legal consequences of no address?

[Daniel K.]

I've been using a lease I got from my RE agent, with no landlord address on it, for years.  Everything worked fine and payments are on Zillow.

I now know that providing a physical contact address is a requirement.  While I am about to provide a 3 day notice to a tenant that I communicate with regularly and whom I've worked with for 2 years, is there anything I can or should do to fix this now or does it not matter?
