It is a fundamental right of the tenant to enjoy the premises free from intrusions or disturbances from the landlord or other tenants. Disturbances could include sound, smells, safety concerns, and other nuisances. There is usually a carveout in this provision that the landlord may enter in certain circumstances, including showing the unit to any prospective tenants, the inspection of the unit, or landlord repairs. There is typically a notice period that the landlord is required to give before they enter a unit. This part of the provision usually outlines exceptions to the notice period for emergency requirements.
