My tenant wants to install Kiln in garage?

[Amira Kalifa]

My tenant has a masters degree in Art and enjoys creating ceramics. She wants to install a kiln in the garage of my 1970s rental house. My first concern was the wiring of the house isn't equipped but she assured me she would pay my electrician to install a sub panel in the garage and add a cement wall. I talked to my insurance lady, and she is going to get back to me on how/if this will impact my policy. On one hand I want to say no and not deal with any potential hazards, on the other hand, this tenant is willing to jump through hoops to get this done and shows her willingness to stay long term while making improvements to the house. The outlet that would be installed could also charge an electric car, so I'm considering that an improvement. Has anyone dealt with this same scenario? Or have an opinion/recommendation that I should consider? This is my 3rd year as a landlord, so those of you with more experience, what would you do in this case? 

Thank you in advance,

Amira

I personally allow my tent to improve the house at their own expense and liability as long as it increases not decreases rentbility to future tenants. Will the installation of the kiln have any other affect on the garage that will have to be removed or change the long term usage. If anything had to be changed back I would a redeposit because people are never as interested to change it after as they are when installing
