What's the law regarding later rent and late fees?

Question Details: My rent is $420 and if we don't pay on the first of the month my landlord will charge a $20 a day late fee starting the second of the month. I that reasonable? Also, my husband gets paid every 2 weeks. His emploryer cut almost $500 causing us to be late on rent when we got the money we owed an extra $100. His job won't cover and we offered $460, what we could afford. However, our landlord said if you don't have it all I won't take but then he said he would take it. The $100 would be added to next month's rent. Is that legal?
