Do I have to put screens on all of the windows?

Situation

My tenant has requested that I install screens on all of the windows of my house.  Do I have to do this?

Response

It is required that you have at least 1 window with a screen on it in each room of the house.  I believe this is to allow a tenant to open a window in each room and not risk bugs or a child falling from the unscreened window.

If you have screens on the windows but they are torn or badly worn so they do not protect against bugs or children, I suggest repairing them or replacing them.  It's not that expensive.
