Periodic tenancy is a type of lease agreement that automatically renews at the end of each rental period until either the landlord or tenant gives notice to terminate it. This arrangement can be month-to-month, week-to-week, or any other defined period, allowing for flexibility in housing situations. Periodic tenancies are often favored for their convenience, enabling tenants to maintain residency without a long-term commitment while providing landlords a steady flow of rental income.
