Polskie prawo rozróżnia dwa rodzaje umów najmu: standardowy (regulowany przez restrykcyjną ustawę o ochronie praw lokatorów) oraz okazjonalny (stosuje się do niego głównie przepisy kodeksu cywilnego)


In the covenant of quiet enjoyment, the landlord promises that during the term of the tenancy no one will disturb the tenant in the tenant's use and enjoyment of the premises. Quiet enjoyment includes the right to exclude others from the premises, the right to peace and quiet, the right to clean premises, and the right to basic services such as heat and hot water and, for high-rise buildings, elevator service. In many respects the implied covenant of quiet enjoyment is similar to an Implied Warranty of habitability, which warrants that the landlord will keep the leased premises in good repair. For example, the failure to provide heat would be a breach of the implied covenant of quiet enjoyment because the lack of heat would interfere with the tenant's use of the premises and would also make the premises uninhabitable, especially in a cold climate.
