I’m in the land lording business (I’ve always hated that term though).
Every state has different laws regarding the rental of properties. Rumor is rumor, you wouldn’t believe some of the things I hear. I would advise a bit of research before taking on your landlord, bad relations are hard to get over.
You don’t give much information IBBen. How long have you lived there? What city do you live in? Do you rent a house, apartment, what? Do the landlords own other properties or just the one you rent? Why in the world would you agree to rent a place with filthy walls in the first place?
Until I know more details, I’ll share the following. You will be in deep if you paint the walls without WRITTEN authorization and can be held responsible for putting it back to what the landlord says was there prior to your moving in.
You shouldn’t just paint over dirty walls, the new paint will come right off.
Here are some ideas that may get better response.
Write a polite letter to your landlord suggesting that perhaps this situation has somehow escaped their attention and is there a chance they could do something about it? Chances are, if the walls are that bad, they will cover the entire cost including labor.
If you get no or a negative response, try your rumor method.
Might it not be easier to simply wash the walls? I’m not defending your landlord mind you, I simply don’t know enough of the situation.
I live in Idaho, but if you can’t find information on your own, e-mail me and I’ll help you find it.
From my perspective, it’s always better to keep the lines of communication open. Most of all, you probably don’t want to piss off your landlord, It’s amazing what harm can be done.
