Liability in rental unit

[Kayla Marek]

My fiance and I have our first rental property all ready to start showing but have one last thing on our checklist. There is no door to the basement. Looks like the previous owners took it out and drywalled it all up. Looks really nice and I don't want to mess around with installing a door. 

My question is, is it a liability to have no door to the basement? Or would it be the tenant's responsibility to put a gate, etc.? 

Building codes don't say much more than having a railing and even stairs. Just want to make sure I'm not missing anything.
