She’s quite possibly is buying a stairway to heaven…if she or her family & friends don’t see this stair hazard or rather the missing stairs.
Of course, it’s unsafe not to have stairs / step where you need them (see pictures above). You may also be surprised to know that this is one of the alarm bells with insurance brokers, as they doesn’t like this added liability being taken on. Infants, children and pets, not to mention a friend on a 2nd beer, may be unable to navigate or misjudge the drop (or step up), if they know it’s even missing in the first place.
As a result, when conditions such as these are present, the homeowner should prevent persons from entering / exiting from these doors until stairs with proper handrails are in place. In addition, there should also be an appropriate landing area atop a staircase so that trip / fall hazards can be minimized. These landing areas will likely also require guardrails with balusters / spindles secured and spaced accordingly. It’s also important that the riser height and tread depths are consistent on the stairs so they are easy to negotiate. Lastly, stair riser heights, tread widths, handrail heights and the height of any guardrails are also critical in reducing the chance of trip / fall hazards.
