Gas or Electric Dryer for Tenants

Hey! Thanks for reading my post. I'm building a laundry room for tenants in my 2 unit property. I personally prefer gas dryers because they are more efficient and less expensive to operate. The cost of electricity is so high right now. But having a gas line in a tenant area, I'm not so sure about. What are your experiences with gas vs. electric for tenants? Thanks in advance!
