Stair Step Red Flag
The bottom of the set of stairs is definitely not
up to code. The reason is that stair risers are not equal lengths and
this could create a trip hazard.
It would obviously be more dangerous walking down this set of stairs in the night time or when it is dark, than walking up to set the stairs in the daytime when it is light.
It is however a good idea that they painted the bottom riser yellow to make the step more visible for anyone walking up the stairs.
This will not be that easy to see when someone is walking down the stairs. Walking down the stairs will be the biggest problem with this set of stairs.
I don't know how many people use this set of stairs but it looks like they are used by at least two apartments.
Problems like this might not be that big of a deal to most people, unless you are one of the people that actually trips and gets hurt, then it will seem like a bigger deal to that person.
These are things that need to be repaired before someone actually falls.
