Tenant wants to install ceiling fans

[Adam Batcheller]

My tenant wants to put ceiling fans in the unit he is renting from me. He said, he would buy the fans and his brother, who is an electrician, would do the wiring and install the fans for free. There is no ceiling lighting now so the electrician would have to do the wiring from the switch box on the wall to ceiling.

My question is, 1) should I allow him to do it ? 2)Get the electrician’s license number. 3) reimburse the tenant by way of paying less rent?
