If there are no smoke detectors am I entitled to any refund?

Hello m:

No. You are entitled to have them installed, though. Write your landlord a certified letter demanding that he installs them. If he doesn't, you can vacate because he is in VIOLATION of your lease AND state law.

More details are needed! What location? Refund of what? Etc. Do you want a helpful answer or do you want us to play guessing games?
