The electrical work is indeed sloppy and unworkmanlike (a general requirement of the electrical codes). I started as an electrician.
First off, type NM (the white cable) coming from the box marked "PRIMARY" is NOT allowed to be used in hoistways. You would think that the fact that everything else that was in conduit or armored cable would have clued in the dolt who installed it. Further, it has no support at all rather than the fittings on the boxes themselves and the fact it's lying on top of other boxes. This is pretty basic code stuff that even an electrician who never did electrical work would not make. The armored cables aren't much better. The one from the same box is not supported at all. Many of the rest of them are not properly supported (the one going to the RED STOP button seems to have completely fallen out of its clamp because one or the other was installed wrong). Both NM and armored cable need to be supported within a foot of the termination and then every 4.5 feet thereafter. Absolutely basic electrical stuff.
Further, both wiring methods need to follow the finished surface. There's too much play in a lot of the wiring for my tastes. You only get 6' on armored cable when going to raised ceiling luminares. You get only two feet going to items when "flexibility is required." None of these situations appear to require such.
I'm concerned about a few other things. On the right side of the hoistway door frame there's a structural piece coming up from the door latch. There's a flexible conduit coming from the top of the hoisway door enclosure loopign over that extension ( where there is a suspicous piece of black tape) and then into what appears to be a ad hoc fitting to a separate piece of flex going to the box with the hand pinch warning sticker on it. I'm not even going to guess about the blue tape.
