How much do halls consider 'general wear and tear'?

I've got a few marks on my uni room walls, mostly caused by scuffs, dirty fingerprints etc. They're not terrible, but against the bright white paint they're fairly noticeable and I'm worried about losing money at the end of the year.
Also, the headboard of my bed used to be nailed to the wall but has since come loose on one side and left a small hole. I don't remember when this happened, I think it was just a gradual thing.

I expect the uni takes some consideration into the fact there will be some general wear and tear in your room, but what's too much? Should I declare it to my halls (and dump myself in it) or assume it's ok (and risk a surprise fine at the end of the year)?
