What is a lease?
A lease is a legally binding contract between a landlord and tenant that grants the tenant the right to occupy a property for a specified period in exchange for rent. Leases define the terms of the tenancy — monthly rent, duration, maintenance responsibilities, rules, and conditions for termination. Most residential leases are either fixed-term (typically 12 months) or month-to-month, with different legal protections and termination procedures for each.

Key facts
- Approximately 44 million U.S. households — about 36% of all households — are renters, according to the U.S. Census Bureau's American Community Survey, making lease law one of the most broadly applicable areas of housing law.
- The median asking rent nationwide reached $1,979 per month in 2025, with wide metro-area variation: Manhattan exceeds $4,000 while many Midwest cities remain below $1,000.
- A fixed-term lease provides the tenant with security of tenure — the landlord cannot raise rent or terminate the tenancy until the lease expires, except for cause. Month-to-month tenancies offer flexibility but less protection.
- Every state has an implied warranty of habitability that supersedes lease terms — a landlord cannot contractually waive the obligation to provide a livable dwelling, even if the lease says otherwise.
- Lease provisions that violate state law are generally unenforceable — clauses waiving the right to a jury trial, requiring the tenant to pay the landlord's attorney fees regardless of outcome, or shortening the statute of limitations are void in many states.
What Are the Key Types of Leases?
- Fixed-term lease: Runs for a set period (usually 12 months). Neither party can terminate early without cause or a lease break clause. At expiration, the lease either renews, converts to month-to-month, or ends — depending on state law and lease terms.
- Month-to-month tenancy: Continues indefinitely until either party gives notice (typically 30 days, though some states require 60 days). Offers flexibility but allows rent increases and termination with relatively short notice.
- Sublease: The original tenant leases the property (or part of it) to a third party. The original tenant remains liable to the landlord. Many leases prohibit subletting without landlord consent.
- Lease-to-own (rent-to-own): A hybrid arrangement where part of the rent applies toward eventual purchase. These carry significant consumer protection concerns and are regulated in many states.
What Must a Lease Include?
While oral leases are enforceable in most states for terms under one year (under the Statute of Frauds), written leases should include:
- Parties and property: Full names of landlord and tenant(s), property address, and description of the rental unit
- Term: Start date, end date (or month-to-month designation), and renewal terms
- Rent: Amount, due date, grace period, late fee amount, and acceptable payment methods
- Security deposit: Amount, where it will be held, conditions for deduction, and return timeline
- Maintenance responsibilities: Who handles repairs, lawn care, snow removal, and appliance replacement
- Rules: Pet policies, noise restrictions, guest policies, parking, smoking
- Termination: Notice requirements, early termination fees, and conditions for non-renewal
What Happens When a Lease Ends?
When a fixed-term lease expires, the outcome depends on state law and lease language:
- Automatic renewal: Some leases auto-renew for another full term unless the tenant gives notice (typically 30-60 days before expiration)
- Month-to-month conversion: A holdover tenant (one who stays past lease expiration without a new agreement) may become a month-to-month tenant depending on state law and landlord consent or acceptance of rent
- Lease termination: The tenant vacates, the landlord conducts a move-out inspection, and the security deposit is returned (minus legitimate deductions) within the state-required timeframe
When Can a Tenant Break a Lease?
Legal grounds for breaking a lease without penalty include:
- Uninhabitable conditions: The landlord has failed to maintain the property in habitable condition after proper notice
- Military deployment: The Servicemembers Civil Relief Act (SCRA) allows qualifying servicemembers to terminate covered residential leases by delivering written notice and military orders. For leases with monthly rent, termination generally takes effect 30 days after the next rent-due date following delivery of notice
- Domestic violence: Most states allow victims of domestic violence to break leases with proper documentation
- Landlord harassment or illegal entry: Repeated violations of quiet enjoyment or privacy rights
- Early termination clause: Many leases include a buyout provision (typically 1-2 months' rent penalty)
State-by-state differences
Lease law is primarily state-governed. Key differences include notice requirements, security deposit limits, implied warranty standards, and tenant remedy options.
| State | Key difference |
|---|---|
| California | Security deposit capped at one month's rent for unfurnished units (AB 12, effective 2024). 30-day notice for tenancies under 1 year, 60 days for longer. Rent increase limits under AB 1482 (5% + CPI, max 10%). |
| New York | Security deposit capped at one month's rent statewide (2019 reform). Deposits must be held in interest-bearing accounts in buildings with 6+ units. For non-rent-regulated units, landlords must provide an itemized deposit deduction list within 14 days. |
| Texas | No statutory limit on security deposit amount. Landlord has 30 days to return deposit. Lease terms are broadly enforceable — Texas courts generally enforce lease provisions that other states might void. |
| Oregon | Statewide rent control: rent increases for covered homes are generally capped each year at the lower of 10% or 7% plus CPI. After the first year, landlords generally need a reason based on the tenant's conduct or a qualifying landlord reason to end a month-to-month tenancy. Ending it for a qualifying landlord reason generally requires 90 days' notice and a payment of one month's rent, with exceptions, including no payment requirement for owners of four or fewer units. |
| Illinois | Chicago RLTO (Residential Landlord Tenant Ordinance) provides stronger protections than state law: 2× security deposit penalty for late return, right to withhold rent for habitability violations, required interest on deposits. |
Questions about lease
Can a landlord raise my rent during a lease?
Not during a fixed-term lease — the rent is locked for the lease period unless the lease explicitly allows mid-term increases (rare in residential leases). For month-to-month tenancies, the landlord can raise rent with proper notice (typically 30 days). In rent-controlled jurisdictions, increases are capped for units and tenancies covered by the applicable rent-control law.
What happens if I break my lease early?
You may owe an early termination fee (if specified in the lease) or rent for the remaining lease term. However, most states require the landlord to mitigate damages by making reasonable efforts to re-rent the unit. You are only liable for rent until the unit is re-rented. Some states cap your exposure at 1-2 months.
Can a landlord refuse to renew my lease?
A landlord can generally decline to renew a lease if the nonrenewal complies with anti-discrimination, anti-retaliation, and applicable just-cause or other statutory protections. However, jurisdictions with just-cause eviction laws (New York, New Jersey, parts of California) require landlords to have a valid reason for non-renewal after a certain tenancy duration.
Is an oral lease enforceable?
Yes, for terms of one year or less under most states' Statute of Frauds. An oral month-to-month tenancy is enforceable, and the tenant has the same basic rights as one with a written lease. However, proving the terms of an oral lease in a dispute is much harder.
What if my lease contains illegal provisions?
Illegal lease provisions are generally unenforceable — a court will strike them while enforcing the rest of the lease. Common unenforceable provisions include waiver of habitability, waiver of right to jury trial (in some states), penalties disguised as liquidated damages, and clauses allowing lockouts or utility shutoffs.
