Judging from the photos, these doors may not have been code-compliant, but they were still able to hinder the spread of smoke and fire, at least to some extent. That does not mean that any old non-compliant door will be fine so we might as well stop worrying about them…one of the biggest issues with fire doors is finding them propped open with a wedge or a more creative device. If the doors are open, they’re worthless.
