Inspecting my apartment for code violations to buy at discount

[Blake Hill]

I currently rent an apartment in a multifamily house that was put on the market about a month ago. The place is falling apart, and if i had to guess has many code violations. How can I go about confirming the violations? Then using that to negotiate a steep discount in the price. My end goal would to get it cheap enough to do renovations and house hack by renting the other two units.
