Some clauses that appear in a written lease or rental agreement are, by the nature of the clause, unenforceable. These include agreements that the landlord can repossess property if the tenant falls behind in the rent, agreements allowing the landlord to enter the rental unit any time, without notice, agreements that tenants will pay for all damages to the rental unit without regard to fault, and agreements that court action entitles the landlord to more money than can be order by the court.
