Hi - thanks for writing back.
YES, if the lease says he will cover all repairs, then he should do just that. Usually, if the landlord refuses to cover the costs, the tenant will take the money for the cost of repairs and take it off of the next month's rent to even things out. If you didn't do that, then you would be able to seek the cost you paid for the repairs - - the entire amount.
If the landlord removed the propane tank to force you to move, that was illegal and you certainly could have acted on that immediately. BUT, your recourse is to file complaints with the court to require the landlord to comply with the lease.
Unfortunately, your recourse is not going to be to ask the court for more time to stay in the property. IF you have more months left on your lease, and IF you are not in default, then you could request to be allowed to stay for the remainder of your lease. However, if the lease term is up or if you are also in default, then you should not expect to be given a protracted period of time to remain there.
IF you are in default because you have had to pay for the repairs - - and if the repairs are as much or more than the rent due - - then you certainly could make that argument as well and claim that you should be given credit for the cost of repairs and be allowed to continue your tenancy. This would ONLY work if the repairs are at least as much as the unpaid rent.
The ADA would protect you if you were being discriminated against in some manner because of your disability. I don't know if that's the case or not, but it sounds more like its a breach of contract matter and doesn't relate to the ADA. Also, the ADA doesn't provide rights or extended protection for renters in terms of time to vacate upon eviction.
Please let me know if you have more questions.
