Comerical unit for rent( tenant want to change 110v to 220v and .

[Lisa Forde]

I am renting out a comercial unit this year, potential tenant who wants to open a take out place says want to change electric outlet from 110v to 220v because will use comercial oven and also need to install 3 sink as is required by city)

Both job need a general contractor and apply permit. Should I let them do that on my unit or should I not?

I will have to sign off the paperworks.
