Does anybody have an idea where we stand if we buy a house that has had stairs replaced, but the spacing of the treads is shallow? The stairs don't need replacing, but it is likely were DIY and they "feel" wrong, too shallow. The railings are not to code but we could easily fix this by adding battens to stop a child falling through the wide openings. My understanding with old buildings is that unless we renovate, there is no requirement to bring things up to code, i.e. lots of units have lower than (current) code balcony railings, but they can be left alone unless work is done, at which time anything not to code needs to be upgraded. I'm just concerned about insurance if someone trips up the stairs and thinks they might "have a go".
