Standard building and fire codes require a min of two exits, generally speaking.Each state, and please note that Florida also uses a county form of government, may amend the standard building code to suit their own state.
II know of some states that the first story may only have one doorway ,and allow windows to be the second egress. You need to check with your state and the specific county you reside in.
I started here at the State of Florida website:

And found:

This is the complete Florida Building Code:

This is the actual builing code regarding egress, actual code term for exit:

Go directly to Section 1004.2 , states each tenant shall have a min of two exits, serving every story, does list some exceptions.
You must review:

To determine the type of residential occupancy you have to deterimine if the exceptions are applicable.
As far as the painted stairs, sometimes common sense must prevail, Again check with the code authority having jurisdiction where you reside, and I am sure painted stairs that do not have any slip-resistant element to the surface will be addressed.
Review the websites I offer, and find out, beginning with you local city about the housing and/or building code agency that will help you.
Hope this helps.
