Your lease is the controlling documents in this matter. Review it closely to see if any part of it addresses your present situation. That being said, even if you have a legal right to collect from the landlord, proof is going to be your biggest hurdle.
I just don't know how you can prove it was the landlord's fault that you got the bedbugs. He will likely defend his position by stating either you brought them with you when you first took possession of the apartment or you brought them in...
As with most Landlord/Tenant matters, you need to thoroughly review your lease. If the lease is silent on this matter, then try submitting your parking receipts to the landlord and see what happens. This is probably not a big enough deal to spend money on a Landlord/Tenant Lawyer. However, if it becomes necessary, you can always hire a local attorney to help you properly understand your rights and liabilities.
You might have a valid complaint, but before you do anything, you should read your lease. Also, you should attempt to calculate just how much this one light in the shed is actually costing you. It might not be worth making a big deal out of this.
If you are intent on bring this matter to your landlord, I suggest you first consult with a local Landlord-Tenant lawyer to review all of your options.
What a horrible experience for you to go through. Yes, you can bring an action against your landlord for your actual damages. Since you have already engaged the services of attorney, before filing a Complaint, it would be wise to seek out his/her advice again.
Your rights and liabilities in this matter are all dictated by your lease. Review your lease carefully to determine when and how the landlord can tell you to vacate the apartment. If you have no written lease, then the terms of your agreement are dictated by state law. It would be wise to speak with a local attorney about your options.
Depending on the language of the Lease, you (and each of your co-tenants) might be individually liable for the entire rent. Practically speakings, if the remaining tenants are willing to cover each month's full rental payment, then you will have nothing to worry about. However, if there is a problem and the landlord decides to file suit against the tenants, you will most likely be on the hook.
Read the lease, talk to your co-tenants, and (if necessary) call a local attorney.
Read your Lease Agreement. Even though you have not moved in, most likely you already have a legally enforceable agreement. With some limitations, the Lease is binding.
Depending on how much money is at stake, it might be wise to pay for a half-hour of an attorney's time to review your situation and advise you of your rights and liabilities.
