Utah Rent Increase Notice Requirements

No Utah statute limits the amount of a rent increase, and the state preempts local rent control. There is no dedicated rent-increase-notice statute; because a month-to-month tenancy can be terminated on 15 calendar days' notice under Utah Code 78B-6-802(1)(b)(i), landlords customarily give at least 15 days' written notice before a new rent amount takes effect, since a tenant rejecting the increase can be required to quit on that notice. The Fit Premises Act separately requires 15-day notice before adding any new non-rent charge to a month-to-month agreement: such a fee is barred unless 'the rental agreement is on a month-to-month basis' and 'the owner provides the renter a 15-day notice of the charge' (Utah Code 57-22-4(5)(b)).

No specific statutory penalty. An increase that takes effect without the notice needed to change a month-to-month term is not enforceable; the prior rent remains owed until proper 15-day notice has run.
