can i sue apartment for lack of parking and my car flooding on the street?

No, I'm afraid not. The apartment complex maintains adequate parking for their residents. It's not negligent of them when others take those spaces against their wishes. Also, you decided where to park your car in a place where your car was flooded...that's your liability. Call your insurance company. Hopefully, you have full insurance that will cover flood water.

An apartment is a building and can NOT be sued. If you do not have an assigned space - then you must park on the street. Your auto insurance is the only one who can help you with your flooded car.

Not successfully, no. No law or other rule requires them to provide any parking at all, let alone enough for everybody, and they of course have no control over flooding on a public road.

Not if you knew there was no guaranteed parking when you signed the lease. Your car insurance should cover the flooding damage.

Absolutely you can. You certainly won't win, and it probably won't even be heard, but you can sue.

no. you can't - why did you move there in the first place if you had to park on the street and didn't like it?

Did your lease state that you would have a parking space?

no, the apt owner has no control over the weather

or floods.

You can sue anyone you want for anything you want, it is not free to sue and you will lose......

That is what your insurance is for. Your apartment building has nothing to do with that.
