Lease Agreement vs Rental Agreement: Understanding the Difference

Last updated: 2026-02-26

When renting residential property, two types of agreements govern the landlord-tenant relationship: Lease Agreements and Rental Agreements. While these terms are sometimes used interchangeably in casual conversation, they have distinct legal meanings that significantly affect the rights and obligations of both landlords and tenants.

Duration: The Fundamental Difference

The primary difference between a Lease Agreement and a Rental Agreement is the duration of the tenancy.

A Lease Agreement establishes a fixed-term tenancy, typically for 12 months, though leases can be for any period, including 6 months, 18 months, 2 years, or longer. During the lease term, the rent amount and all other terms are locked in. Neither the landlord nor the tenant can change the terms unilaterally until the lease expires.

A Rental Agreement establishes a month-to-month tenancy (sometimes called a periodic tenancy). The agreement automatically renews at the end of each rental period unless either party provides proper notice of termination. The terms can be changed at any renewal period with proper notice.

Renewal and Expiration

When a Lease Agreement expires, the tenancy does not automatically continue under the same terms. Depending on the lease provisions and state law, several things can happen. The parties may sign a new lease for another fixed term. The tenancy may convert to a month-to-month arrangement if the tenant remains with the landlord's consent (this is the default in most states). The tenant may be required to vacate. Many leases include an automatic renewal clause that extends the lease for another term unless one party provides notice of non-renewal within a specified window, often 30 to 60 days before the end of the lease.

A Rental Agreement renews automatically each month. It continues indefinitely until one party gives proper notice of termination. The automatic renewal provides simplicity but less certainty for both parties.

Rent Increases

A Lease Agreement provides rent stability for the tenant. The landlord cannot increase rent during the lease term unless the lease explicitly allows for it, which is uncommon in standard residential leases. The tenant knows exactly what they will pay for the entire duration of the lease.

A Rental Agreement allows the landlord to increase rent at each renewal period, subject to proper notice requirements. Most states require 30 days' notice for a rent increase, though some require 60 days. In jurisdictions with rent control or rent stabilization (such as New York City, San Francisco, Los Angeles, and several other California cities), rent increases may be limited to a certain percentage annually, regardless of the type of agreement.

Termination and Notice Requirements

Terminating a Lease Agreement before it expires is generally more difficult. The lease creates a binding obligation for the entire term. If a tenant breaks a lease early, they may be liable for the remaining rent due under the lease, though most states require the landlord to make reasonable efforts to re-rent the unit (the duty to mitigate damages). Some leases include an early termination clause that allows the tenant to break the lease by paying a penalty, commonly one to two months' rent.

Terminating a Rental Agreement requires only proper notice from either party. The notice period is typically 30 days in most states, though some states require longer notice. California, for example, requires 60 days' notice from landlords if the tenant has lived in the unit for more than one year, but only 30 days' notice from the tenant. The ease of termination provides flexibility but also less security.

Tenant Protections

Tenants generally have stronger protections under a Lease Agreement. The fixed term guarantees the right to occupy the premises for the duration of the lease, as long as the tenant complies with the lease terms. The landlord cannot ask the tenant to leave simply because they want to sell the property, renovate, or move in a family member (during the lease term).

Under a Rental Agreement, tenants have less security of tenure. The landlord can terminate the tenancy by providing proper notice, without needing to state a reason in most states (though in jurisdictions with just cause eviction protections, the landlord may need a valid reason). This makes month-to-month tenants more vulnerable to displacement, particularly in competitive rental markets.

However, both lease and rental tenants are protected by state and local landlord-tenant laws, fair housing laws, the implied warranty of habitability, and rules governing security deposits, maintenance responsibilities, and eviction procedures.

Landlord Flexibility

Landlords generally have more flexibility under a Rental Agreement. They can adjust rent to market conditions each month, change terms such as pet policies or utility responsibilities with proper notice, terminate the tenancy with proper notice if they want to sell the property, renovate, or use it for another purpose, and respond more quickly to changing market conditions.

Under a Lease Agreement, landlords are locked into the agreed terms for the entire lease period. If market rents increase significantly, the landlord cannot benefit until the lease expires. If the landlord needs the property for personal use or wants to sell it, they must wait until the lease term ends (unless the lease includes specific provisions for these situations).

Security Deposits

Security deposit rules are generally the same regardless of whether the tenancy is under a Lease Agreement or Rental Agreement, as they are governed by state law. Most states limit the maximum security deposit (commonly one to two months' rent), require the deposit to be held in a separate account or returned with interest, require the landlord to provide an itemized statement of deductions within a specified period after move-out (typically 14 to 30 days), and prohibit non-refundable deposits (in some states).

Which Is Better for Landlords?

The answer depends on the landlord's priorities. A Lease Agreement is better when the landlord wants guaranteed occupancy for a fixed period to ensure consistent rental income, when the landlord wants to reduce turnover costs (advertising, screening, cleaning, and potential vacancy between tenants), and when the property is in a market where finding tenants may be challenging.

A Rental Agreement is better when the landlord anticipates needing the property back (for personal use, sale, or renovation), when the rental market is rising and the landlord wants to adjust rent to market rates regularly, and when the landlord wants maximum flexibility to change terms or terminate the tenancy.

Which Is Better for Tenants?

Similarly, the best choice depends on the tenant's situation. A Lease Agreement is better when the tenant wants stability and certainty, when the tenant is settling into a new area and wants guaranteed housing for a fixed period, and when the tenant is in a competitive rental market where rents are rising.

A Rental Agreement is better when the tenant is unsure how long they will stay, when the tenant may need to relocate for work or personal reasons on short notice, and when the tenant wants the flexibility to leave without breaking a lease.

State Law Variations

State laws add additional layers of complexity. Some states, like California, have extensive statutory protections for tenants regardless of agreement type, including rent control in certain cities, just cause eviction requirements, mandatory relocation assistance, and strict limits on security deposits and late fees. Other states, like Texas and Georgia, are more landlord-friendly with fewer restrictions on rent increases, termination, and eviction.
