Can I charge water mid lease?

[Marco Gonzales]

We currently pay water, and the residents pay electricity. We are planning to charge 25-35 dollars per unit to recover the 6-7k a year we pay for water. My question is, Do I have to wait for the residents lease to end before I can start charging residents water or can I give a few months notice and begin charging at the beginning of 2022. The property is in Texas. Thanks!
