Official building inspector sought

[concrete.livejournal.com]

I'm renting in an old building, and my bathrom was so shoddily constructed (holes in the grout, non-waterproof drywall behind it) that the tiled bathroom wall caved in where the shower sprays.

My landlady just told me that I am responsible for paying for the wall, because "I was not showering properly, because the water should only flow on my body, and not on the wall."

(moment of silence to let this sink in appropriately)

So now I'm looking for a building inspector that can look at the wall and write up something official about the construction and the damage.

Where should I go, what should I ask for, how much would this run?

Thank you, and in the meantime I'll be practicing proper showering procedures.
