Lease prohibits balcony use - tenant uses balcony and says fix it

[Mike Cartwright]

Hi BP,

This is my first rental I'm land lording. The home has a second story balcony attached to a bedroom. This balcony has a loose-ish railing and a semi-soft spot in the corner. Because of this liability, I don't want anyone on the balcony. The lease says: 

"Second floor balcony may only be used as an emergency exit. Landlord is not responsible for any injuries sustained by Tenant or guests of Tenant as a result of the emergency exit being used."

Within days of signing the lease, the tenant sent me a video of themselves on the balcony pointing to the spot and saying there is a soft spot and that I need to fix it ASAP.

Am I obligated to fix this if they've signed a lease addendum with the above-referenced language?

Again, I'm new to the real estate game so I'm open to any feedback or constructive criticism.

Thanks,

Mike
