A lease is a legally binding contract in which one party, the owner (the lessor, or landlord), lets another party (the lessee, or tenant) use property for a set period in exchange for regular payments. The lessee gets the right to occupy or use the asset. Ownership stays with the lessor, who collects payment and gets the property back when the lease ends. If either side fails to meet its obligations, the other can pursue legal remedies.

How a Lease Works

The landlord drafts the lease, and the tenant signs it before moving in, which shows agreement to its terms. Leases can be verbal, but most are written, and a written copy is what both sides rely on when a dispute comes up. Each party should keep a signed copy.

Once signed, the lease binds both parties for its full term. The tenant owes rent on the stated schedule even if their plans change. The landlord cannot raise the rent or change the rules midway unless the lease allows it, and must hand over the property and meet any duties the contract or law assigns, such as making repairs.

What a lease agreement typically contains

Not every lease looks the same, but a residential lease usually covers:

• The property address
• The names of the landlord and tenant
• The rent amount and the date it is due
• The security deposit and the conditions for getting it back
• The lease duration, including start and end dates
• Who handles maintenance, repairs and utilities
• Rules such as pet policies and occupancy limits
• The consequences of breaching the contract

The lease term

The lease term is how long the agreement runs. A fixed-term lease, often 12 months for an apartment, locks in the rent and the occupancy right until a specific end date. A periodic lease, such as month-to-month, renews automatically each period until one side gives the notice the lease or local law requires. At the end of a fixed term, a lease may expire, renew on new terms, or convert to a month-to-month arrangement, depending on what it says.

Types of Leases

Residential leases

Most residential leases are standard forms with the same terms for all tenants in a building. The tenant typically pays rent plus some utilities, and the landlord covers the building’s taxes, insurance and major repairs.

Commercial leases

Commercial leases are usually negotiated with each tenant and typically run from one to 10 years. Larger tenants often sign longer and more complex agreements. Their main difference from residential leases is how property costs are split, and these structures generally put more responsibility on the tenant. The four most common types are:

• Single-net lease: The tenant pays rent plus property taxes.
• Double-net lease: The tenant pays rent, property taxes and insurance.
• Triple-net lease: The tenant pays rent, property taxes, insurance and maintenance costs.
• Gross lease: The tenant pays rent only, and the landlord covers the other property costs.

The headline rent on a triple-net lease can look lower than on a gross lease for the same space, because the tenant carries costs that the landlord would otherwise fold into the rent. Comparing leases means comparing total occupancy cost, not just base rent.

Equipment and vehicle leases

Leasing is not limited to buildings. Businesses lease equipment and individuals lease cars under the same basic arrangement: regular payments for the use of an asset for a set term, with the asset returned at the end unless the contract offers a purchase option. A car lease usually limits mileage and charges for excess wear, because the lessor gets the vehicle back and its value depends on its condition.

Example of a Lease

Hypothetical example for illustration only.

A tenant signs a 12-month lease on an apartment at $1,500 a month, with a $1,500 security deposit and rent due on the first of each month.

• Total rent commitment: 12 × $1,500 = $18,000 over the term.
• Upfront cost at signing: first month’s rent plus deposit = $3,000, assuming no other move-in fees.
• If the tenant leaves after five months without an agreement: seven months remain, so up to 7 × $1,500 = $10,500 of rent could be claimed. The actual amount depends on the lease’s termination terms and state law. In states that require landlords to make reasonable efforts to re-rent, the tenant’s liability may shrink once a new tenant starts paying.
• If the lease has an early termination clause allowing exit with 60 days’ notice and a fee equal to one month’s rent, the cost of leaving is known in advance: the rent for the notice period plus $1,500.

Lease vs. Rent and Other Common Confusions

Lease vs. rent. “Rent” is the payment. “Renting” and “leasing” are often used interchangeably in everyday speech, but landlords commonly use “lease” for a fixed-term contract and “rental agreement” for a short, periodic one such as month-to-month. The fixed-term lease gives the tenant price and occupancy stability; the periodic agreement gives both sides more flexibility to leave or change terms with notice.

Lessor vs. lessee. The lessor owns the property and grants its use. The lessee pays to use it. “Leased” property is property currently under such a contract.

Lease vs. purchase. A lessee builds no ownership in the asset through payments. Any rise in the property’s value belongs to the owner, and lease payments are an expense rather than an addition to net worth, unless the contract includes a purchase option the lessee exercises.

Sublease. A sublease is a second agreement in which the original tenant rents the property to someone else. The original tenant usually stays responsible to the landlord, and many leases require the landlord’s permission first.

Breaking a Lease

A tenant who leaves early without negotiating with the landlord can face a civil lawsuit, a derogatory mark on their credit report, or both. Either can make it harder to rent a new home later. Tenants may be required to pay penalties or the remaining rent on the lease. Landlords who break a lease face consequences too, such as having to provide alternate housing or defending a legal dispute.

The less damaging routes are usually negotiated. Depending on the lease and the landlord, giving a set amount of notice or forfeiting the security deposit may end the lease with no further liability. Some leases include early termination clauses for specific events, such as a job relocation or divorce-related hardship. A tenant may also be able to end the lease if the landlord fails to meet contractual duties, for example by not making timely repairs.

Protections for certain tenants

Some groups have legal rights to end a lease early:

• Servicemembers: Under the federal Servicemembers Civil Relief Act, servicemembers can terminate a lease when they receive active-duty orders requiring relocation for more than 90 days.
• Domestic violence survivors: Many states let victims end a lease without penalty. The abuse generally must be recent, often within the past year, and the tenant usually needs proof such as a protective order or a police report.
• Tenants with serious health conditions: Some states allow renters, especially older adults, to end a lease early when disability, illness or a medical crisis makes the home unlivable. A letter from a doctor, hospital or other medical professional is usually required.

Even under these protections, the tenant generally still has to give the landlord written notice, often 30 days in advance.

Limitations of a Lease

A lease cannot override state or federal law. A clause letting the landlord enter at any time without notice, or one allowing the landlord to recover more through the courts than statutory limits permit, is not enforceable even if the tenant signed it.

The other main limitation is rigidity. The stability that protects both parties also locks them in, so a lease that suited a tenant at signing can become expensive if their circumstances change before the term ends.

The Bottom Line

Renters, business tenants and anyone leasing a car or equipment should read the term, cost split and termination clauses before signing. The lease binds both sides for its full term, so comparing total occupancy cost and knowing the exit options matters more than the headline rent. A tenant who needs to leave early usually does less damage by negotiating with the landlord or using a legal protection than by walking away.
