Can I require tenant to pay fees before renewing their lease for another term?

[Sandy Magyar]

This particular tenant's lease is set to expire soon. They still owe $300 for a utility bill and $150 for removing and dumping the unit's fridge by the dumpster. The owner would like to retain this tenant. Can I add language to our lease renewal letter that includes the requirement that the above fees get paid? What are the rules around this?
