A lease agreement (also called a lease or rental lease) is a legally binding contract between a landlord and a tenant that defines the terms under which the tenant rents a property. It covers everything from the monthly rent and security deposit to lease dates, pets, utilities, and what happens when something goes wrong.
Whether you are renting out a room in your home or signing a year-long lease for an apartment, a written agreement protects both parties. In this guide, we explain what a lease agreement is, what it must include, and how to create one — free and without a lawyer.
What Is a Lease Agreement?
A lease agreement is a written contract that grants a tenant the right to occupy a property for a specific period in exchange for rent. It is governed by the laws of the state where the property is located.
The two parties are:
- Landlord (lessor) — the property owner who grants the right to occupy
- Tenant (lessee) — the person who pays rent to occupy the property
A valid lease agreement typically includes the names of both parties, the property address, the lease term, the rent amount, the security deposit, and the rights and responsibilities of each side.
Lease Agreement vs. Rental Agreement: What's the Difference?
People often use the terms interchangeably, but there is a practical difference:
- Lease agreement — usually a fixed term (e.g., 12 months). Rent and terms are locked for the duration. Neither party can change the terms or terminate early without a penalty or legal cause.
- Rental agreement — usually a month-to-month arrangement that renews automatically each month. Either party can end it with proper notice (typically 30 days in most states).
Which is better for you? A fixed-term lease gives both parties stability; a month-to-month agreement gives flexibility. Many landlords start with a fixed lease and let it roll into a month-to-month arrangement after it expires.
What Must a Lease Agreement Include?
A well-drafted lease agreement should clearly state:
- Parties — full legal names of landlord and tenant, plus contact information
- Premises — the property address and what is included (parking, storage, appliances)
- Lease term — start date, end date, and renewal terms
- Rent — the monthly amount, the due date, the late fee, and accepted payment methods
- Security deposit — the amount, its purpose, and the timeline for its return
- Utilities — which utilities are included in rent and which the tenant pays
- Pets — whether pets are allowed, and any pet fee or deposit
- House rules — noise, guests, smoking, and shared-space rules
- Subletting — whether the tenant may sublet or assign the lease
- Termination — notice requirements and what happens on breach
Missing any of these terms is a common source of disputes. A complete, written agreement prevents most misunderstandings before they start.
Common Types of Lease Agreements
Depending on your situation, you may need one of these:
| Type | Best for |
|---|---|
| Residential lease agreement | Standard apartment or house rental with a fixed term |
| Room rental agreement | Renting a room inside a shared residence |
| Month-to-month lease | Flexible, rolling tenancy with 30-day notice |
| Roommate agreement | Defining responsibilities between roommates sharing a home |
| Sublease agreement | Tenant rents out the property (or part of it) to another person |
Each type has slightly different terms. For example, a room rental agreement focuses on shared spaces and utilities, while a standard lease agreement covers the whole property.
Landlord and Tenant Responsibilities
A good lease agreement defines what each side must do:
Landlord responsibilities:
- Maintain the property in a habitable condition
- Make necessary repairs in a timely manner
- Return the security deposit within the legally required timeframe, less lawful deductions
- Provide proper notice before entering the premises
Tenant responsibilities:
- Pay rent on time
- Keep the property clean and undamaged (normal wear and tear excepted)
- Follow house rules and building regulations
- Give proper notice before moving out
Are Lease Agreements Different by State?
Yes. Rental laws vary significantly by state — and sometimes by city. Examples of state-specific rules include:
- Security deposit limits (e.g., California limits deposits to a certain multiple of rent)
- Required notice periods for terminating a month-to-month lease (typically 30 days, but longer in some states)
- Required disclosures (e.g., lead-based paint for pre-1978 buildings)
- Rent increase notice requirements
Always verify your state's requirements before finalizing an agreement. Our state-specific pages summarize key points for each state.

Frequently Asked Questions
Is a verbal lease agreement legal? In most states, oral leases are valid for terms under one year. However, a written agreement is strongly recommended — it is much easier to enforce and prevents disputes.
Can I write my own lease agreement? Yes. As long as it complies with state law and is signed by both parties, a self-written lease can be legally binding. Using a template generator helps you include all essential terms.
What happens when a fixed-term lease ends? The lease either renews (often converting to month-to-month), or the tenant vacates. Check your lease for the renewal clause.
Is a lease agreement the same as a rental application? No. A rental application collects tenant information for screening. A lease agreement is the actual contract for occupancy.
