@Jackie Liu you probably have enough info to deny their application, but if you want to continue to try to approve:1) Ask applicant for copies of their lease(s) to support they've been there for 4 years and who PMC is.2) Get 2023 W-2 to see what address is on it3) Ask them to obtain and provide you with their FULL electricity account history.

To me this certainly includes;  plumbing and electrical.   

Electrical fire hazards IMO- MOST IMPORTANT: It sounds like they are not happy.

So I’m in a bit of a bind, I have a duplex I’m house hacking we remodeled entire thing, new hvac, electric panels, electric main, updated plumbing, water heaters, furnace, install central air, roof.

I have redone the foundation, all new electric, all new plumbing (PVC to the street), all new kitchen, added a bath, new flooring, all new windows/doors, updated all insulated while walls were open for electrical, new furnace/AC, new siding.

I would probably choose to do the electrical plumbing first.

The house is about 70% complete but still needs electrical, plumbing, and AC brought up to code and the finish out to be completed.

Electrical or plumbing need moved? 

@Brett JurgensSolar on my house would be around $40k and my electric bill is not even 200.
