Inspection finds noncompliant structures

[Cassandra Brown]

I made an offer on an older triplex building and the inspection found that the stairwell into the basement is noncompliant in terms of building code width and stair risers.  It would be almost impossible to fix given the structure of the house. My realtor tells me that is will be grandfthered but I can't find any code sections that say so. I'm concerned about landlord safety liability.   Should I be?

Thanks
