In almost all cases, 24 hours notice must be provided to a tenant in order for lawful access to the property. In some cases, where a tenant or landlord has provided notice to terminate a lease, less than 24 hours notice can be provided (for instance in the event that the landlord intends to show the property to a prospective renter) as long as reasonable effort has been made by the landlord to gain entry. In this case, the law permits shorter notice periods.
