A nuisance is a condition or use of property that interferes with adjoining landowners’ (neighbors) use and enjoyment of their properties; or endangers the life, health, enjoyment, or safety of others; or is offensive to others. Loud noises, foul odors, unsightly conditions, and illegal or immoral activities (such as prostitution or illegal drug activity) on a property are common examples of nuisances.

Trash, litter, uncut grass or vegetation, untrimmed trees, graffiti, and abandoned motor vehicles and tires are also common subjects of nuisance abatement efforts—often undertaken by a city or town’s code compliance or code enforcement department or division.

Abatement is generally the act of stopping, eliminating, or nullifying some condition or activity. Nuisance abatement or abatement of a nuisance generally includes stopping or eliminating a noise, odor, unsightly condition, or other nuisance—or repairing or demolishing a home, apartment complex, or other building the owner has failed to maintain and that endangers the life, health, safety, or life enjoyment of persons in the neighborhood.

State laws (statutes) often provide local governments with certain nuisance abatement powers to compel the owner of a property to fix or remedy the conditions creating a nuisance—and if the owner fails to do so, the local government may do so, such as by demolishing or razing a building.

Under some circumstances the local government may choose to repair or rehabilitate the nuisance condition—or remove, remediate, transport, and dispose of materials or property on the premises that are creating the nuisance.

Local governments may also have the right to prohibit access to the premises by some or all persons, and to control access to the premises.

In Alaska, a nuisance is defined as any condition or use of property that negatively impacts neighboring landowners' ability to enjoy their property, poses a danger to life, health, or safety, or is offensive to others. Examples include loud noises, foul odors, unsightly conditions, and illegal activities. Common nuisances also encompass environmental degradation such as litter, overgrown vegetation, and abandoned vehicles. Nuisance abatement refers to the process of addressing and remedying these issues, which can involve measures such as stopping the nuisance, repairing, or demolishing unsafe structures. Alaska state statutes empower local governments to enforce nuisance abatement. This can involve requiring property owners to rectify the nuisance conditions, and if they fail to comply, the local government may intervene directly, which could include making repairs, demolishing buildings, or even restricting access to the property. These actions are typically carried out by a city or town's code compliance or enforcement department.
