Building codes and hand rail question
For a residential house that was built in 1950's, before the building code required hand rails for stairs over 4 risers:
there is a back basement exterior staircase, to walk out basement door. this is covered staircase with locked door at top and bottom.
if the house predates the code, is retrofitting a hand rail to comply with the current code a requirement?
I was always under impression only time a house had to be brought up to current code was if a building permit was applied for?
Or are there certain safety related building codes that must always be complied with regardless of age of house?
Any thought on this appreciated!
