In many states, courts recognize a landlord's implied warranty or covenant (promise) of quiet enjoyment in a residential lease agreement. The implied warranty or covenant of quiet enjoyment generally requires the landlord to prevent unreasonable and unexpected noise and other disturbances that might prevent the tenant from enjoying the peace and quiet of the leased premises. The implied warranty or covenant of quiet enjoyment is often referred to as the tenant's right to quiet enjoyment.

Some states—such as California—have specifically stated in their statutes (laws enacted by the state legislature) that every residential lease agreement includes an implied covenant of quiet enjoyment. City and municipal codes and ordinances may also provide for an implied covenant of quiet enjoyment. And some residential lease agreements include an express (stated) covenant of quiet enjoyment.

Quiet enjoyment can be difficult to define due to the great variations in residential living in the United States. A tenant who leases an apartment on a busy street or bar district in a large city cannot reasonably have the same expectation of quiet as a tenant who leases a home in the countryside.

But there are some disturbances that a tenant could not reasonably anticipate and should not have to suffer. Some examples of disturbances that may interfere with a tenant’s right to quiet enjoyment include:

• Ongoing or recurring disruptive noises or behaviors from neighbors, such as loud music, barking dogs, late-night parties (if the landlord won’t stop them), or loud domestic arguments from neighboring apartments

• A landlord entering the leased premises too often, unnecessarily, or without proper notice

• Unnecessary, ongoing, and previously undisclosed construction, improvements, upgrades, or maintenance work that continues much longer than initially stated

• A landlord harassing a tenant or a tenant’s guest in person or by phone

• Cockroaches, rats, or other pests or vermin living in the walls and making audible noises

In contrast with these recurring or ongoing nuisances or disturbances that may breach the landlord’s implied warranty or covenant of quiet enjoyment, reasonable or one-time disturbances that don’t necessarily breach the landlord’s implied warranty or covenant of quiet enjoyment include:

• emergency maintenance or repairs in the leased premises

• scheduled maintenance or repairs or upgrades completed in the leased premises when the landlord provides the proper notice that it or its representative will be in the leased premises for this purpose

• upstairs or adjoining neighbors walking around, talking, laughing, watching television, listening to music, or having friends or family over at reasonable times and noise levels

• a neighbor’s smoke alarm going off when cooking dinner

• the landlord regularly calling or knocking on the door to collect past due rent

• routine inspections upon proper notice, as provided in the lease agreement

• reasonable noise levels from community members and guests gathering at a community swimming pool, basketball court, or other activity in the common areas of the leased premises.

In New Jersey, the concept of the implied covenant of quiet enjoyment is recognized and protected under landlord-tenant law. This covenant ensures that tenants have the right to peacefully enjoy their rented premises without unreasonable disturbances from landlords or other sources. While New Jersey statutes may not explicitly state the covenant of quiet enjoyment, it is a common law principle that courts within the state uphold. Landlords are expected to prevent recurring or ongoing nuisances such as excessive noise, unwarranted entry into the premises, and harassment. However, tenants must also be reasonable in their expectations, acknowledging that living in a community involves some level of noise and disturbance. One-time or reasonable disturbances, such as emergency repairs or routine maintenance with proper notice, do not typically constitute a breach of the covenant. If a tenant in New Jersey believes their right to quiet enjoyment has been violated, they may seek legal remedies, which could include terminating the lease or seeking damages. An attorney can provide specific guidance based on the circumstances of the disturbance and the terms of the lease agreement.
