It'll depend on who "owns" the leak. If it's the other tenant (overflowing sink for instance), then there's your defendent. If it's a broken pipe, it's the owner of the property. The landlord will likely not be personally liable (unless he's also the owner), but will act as owner's representitive. (Or you can subpeona the owner :} ) You're almost certainly going to wind up in court over this one though, so prepare.
The car owner is responsible.
If in California your neighbor is responsible for any damage that his tree has done to your property.
well in my book he's the landlord so he can do whatever he wants favours wise I suppose..
No They Cant
Unless the person that hit you is found, you are responsible for the damages (just like if someone threw a brick through the window of your house). Always insure your car. If you are not going to drive it, buy garage insurance
Unless the garage with an automatic opening system is specifically on the lease they are not required to provide one. If you are renting a garage they do have to ensure that you have some way to open it, be it by hand or electronically.
Auto Insurance.
If you have wind and hail coverage on your policy and the detached garage is a covered structure on that policy then Yes, your policy would cover the damages.
Certainly not. This is not a habitability issue, and the tenant knew what he was renting.
It depends on what is damaged, but most probably home and contents
I'm no lawyer but... The simplest answer is no. If it had no door when you agreed to rent it, then you can't expect him to improve it after you sign. If it had one but it fell off, then he must repair it. If there is a door from garage to house that has no lock on it, then you may be in a position to demand either a lock on that door or a door on the garage.
This depends on the terms of your lease, if you have one, and the type of dwelling you're living in. In most detached homes it shouldn't be necessary to tell your landlord unless it's otherwise specifically stated on the lease.
