Since you are asking "how to tell him" that the cabinets are moldy, I would suggest this. When giving him the rent for the next month, present him with a list of "new tenant issues". (There are always things that one encounters when moving in and as a landlord he knows this).
List the mold on (or in) the cabinets. And the issue of no light at entrance, which would be a liability if you fell in the dark. And then whatever else you need such as electrical covers on outlets - whatever.
In the meantime, it sounds as though there is no air getting to the cabinets. Are they moldy on the outside or inside? If outside put a fan on the counter to keep air circulating.
If inside clean with bleach and prop door open for a while. It sounds as though dampness is coming from somewhere. Have him buy some Kilz and then paint the cabinets.
I live in the basement apartment" This is a bane of many basements. A word of advice: Your apartment may NOT be legal. Check with your local building department on the regulations for egress (exits) in case of emergency.
Most building codes require the bedroom window be no more than a few feet off the floor and wider than normal. Plus, if there is a significant grade drop, there needs to be access (ladder/steps) from the bottom of the window well to ground-level. Many people renovate houses and put apartments in the basement illegally.
Too often the authorities find out AFTER a death from a fire.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
