Notice to Quit in Connecituct

[Sunny Rajvansh]

Hello Bigger Pockets,

I have a few questions and I really appreciate your feedback. I understand there is not particular answers to my question in current situation. I wanted to know this in normal circumstances. 

1. What is the actual day I can charge late fees from tenant in Connecticut? From what I know CT gives 9 day grace period so I can charge late fees on the 10th?

2. What is the maximum late fees can be charged? I read $10 or 5% of the amount due which ever is less, I cant imagine 5% of any rent due can be below $10. I wonder if that is per day.

3. When can I serve the notice to quit? I need to give atleast 3 days for tenant to move out from the day of notice to quit, so can i serve the notice on the 7th of the month?

4. Now this one is related to the pandemic, If my tenant is not able to pay rent, can I ask for or are the suppose to provide any paper proof that they are facing job loss or reduction in hours ar work? How do I know if they are actually facning hardship from the pandemic?

Thank you,
