Do I need to install a handrail?

[Brian Greenway]

I installed a flight of 5 steps (Treated Lumber, done nicely) up the rise from the driveway, towards the walkway to the front door of Single Family Home.

Run is about 10 feet, rise is about 25 inches.

There is 10 feet of concrete walkway between these steps and the 3 step stoop, rising to front door. There is a metal hand rail here at the front steps. 

It didn't feel necessary for a handrail at the landscape steps before, but I'm starting to second guess myself. 

Would it be in my best interest to install one? Would I be liable as the landlord, should someone take a tumble entering/exiting the property via these steps.

There is also a larger stairway of 7 steps, leading to the back door. Run of 16 feet, rise of about 36 inches. I'm also curious if I would need one here, also.
