| Nevada | No statewide rent control statute in NRS Ch. 118A. Rent increases require written notice at least 60 days in advance (30 days for periodic tenancies of less than one month).

Whether a local rent-control ordinance would fall within these powers has not been decided by statute or by a Nevada appellate court.
