I believe NYS law is 15 days to keep the things, but I have also read 30 days is standard. i want to get the property cleaned up and start working on it...

Legal requirements for giving notice include checking local and state laws, providing written notice, clear communication, specifying the move-out date, offering assistance, offering more than 30 days notice as a goodwill gesture, and providing 45-60 days notice for a smooth transition, reducing stress and potential conflict.Good luck!

When the pandemic hit and the tenants stopped paying, and we worried day and night about payments, whether to evict, laws, paperwork, I decided to call someone.

If there are any laws I need to know or if its even allowed in the area of Philly I'm looking at.

You need to put on your landlord pants and lay down the law.

Hi I have a situation that I really need help with and I am hoping someone who is well versed on real estate laws will read this and possibly help me get the answers I need.

Hi Jerrell, I would recommend consulting with a local NYC RE attorney to confirm NYC tenant/landlord laws and regulations 

Check your local laws to see if you can simply not renew her lease (vs evicting). 

Is there any laws address that? 

Adding an ADU does not make the property a duplex in the jargon of the laws.
