Learning how to write a lease agreement is one of the first real tests of being a landlord. A weak lease leaves gaps that turn into arguments over rent, repairs, or move-out dates. This guide walks through every clause you need, in the order you need it, so your lease term stays clear from day one. By the end, you will have a document that protects your property and holds up if a dispute ever reaches a judge.
Can You Write Your Own Lease Agreement?
Yes, you can write your own lease agreement. No federal law requires that a residential lease agreement be drafted by an attorney, and many landlords start with a lease agreement template and adjust it to their property and state.
A sample lease agreement template gives you a ready-made structure, and a sample lease agreement for a rental listing shows how other landlords phrase common clauses. Free examples of rental agreements are easy to find online, but treat them as a starting point, since state rules vary. A handwritten lease is legal in most states if it names both parties, states the rent and term, and is signed by everyone.
Accuracy is the real tradeoff. A rental contract agreement only protects you if it matches your state's landlord-tenant rules on notice, deposits, and disclosures. The distinction between a rental agreement and a lease mostly comes down to wording, since the terms are used interchangeably in everyday conversation, though a lease usually locks in a fixed term while a rental agreement can run month-to-month.
Start from a residential lease agreement template built for your state, then edit it line by line.
How to Write a Lease Agreement Step by Step
The format of a lease agreement follows a simple order: parties, property, term, rent, and rules. Before you write, separate what you want from how you say it. A provision is the outcome you want, like no smoking in the unit. A clause is the legal wording that makes it enforceable. List your provisions first, then turn each one into a clear clause, since a vague clause won't hold up. That's why vague language causes most disputes.
Here's the order we recommend, so nothing gets left out.
1. Identify the Landlord and All Tenants
Open the lease with the full legal names of every adult who will live in the unit, plus your own name or your property management entity. List a guarantor or cosigner here, too, if one applicant needs income backup. Naming every adult tenant, not just the applicant who signed the application, keeps you from chasing rent from a roommate who was never on paper.
If you're renting to more than one adult, be specific about who is legally responsible for what. This single detail prevents a huge share of the disputes we see later in a tenancy.
2. Describe the Rental Property
Write the full street address, unit number, and a short property description: square footage, bedroom and bathroom count, parking spot, and any storage space included. Note what's furnished, if anything, and which appliances stay with the unit.
A precise property description also sets occupancy limits for the address, so there's no confusion later about how many people can legally live there. Skip vague phrases like "the apartment" and write the address exactly as it appears on the deed or lease record.
3. Choose the Lease Type and Set the Rental Term
Decide between a fixed-term lease and a month-to-month lease. The lease term (fixed-term vs month-to-month) decision shapes almost everything else in the document, from renewal language to how much notice either side owes before moving out.
A fixed-term lease, usually 12 months, gives you predictable income and a locked-in tenant. A month-to-month lease gives you flexibility but less stability. Whichever you pick, state the start date and end date in plain numbers, not “one year from move-in."
4. Set the Rent and Payment Terms
Spell out the monthly rent amount, the rent due date, accepted payment methods, and where payment should go. Then write your late fee policy: the flat fee or percentage charged, and the exact day it kicks in.
Include a grace period if your state requires one, or offer one as a courtesy. A three or five-day period is common, but check your local law first, since some states cap the amount.
If you plan to raise the rent later, check your state's notice rules first, often 30 to 90 days depending on the increase, and confirm whether local rent control caps what you can charge.
5. Define the Security Deposit Terms
Your security deposit terms should cover the dollar amount, where the funds are held, and the conditions under which you can deduct from it. Many states cap the deposit at one or two months' rent, so confirm your local limit before you write the figure.
Explain how and when you will return the deposit after move-out, and reference your move-out deposit process so the tenant knows what documentation to expect. Clear deposit language prevents most of the small claims disputes landlords face after a tenant leaves.
6. Assign Utilities, Maintenance, and Repair Responsibilities
State which utilities the landlord covers and which the tenant pays directly. List who handles lawn care, snow removal, pest control, and minor repairs like a clogged drain versus major repairs like a broken furnace.
Being specific here avoids the common argument over "who was supposed to call the plumber." A short table or bullet list works well for this section since tenants scan it quickly when something breaks.
7. Add Property Rules and Restrictions
Cover smoking, noise, guest limits, and whether pets are allowed. If you allow pets, attach a pet addendum that spells out breed or weight limits, pet deposits, and cleanup expectations.
These rules also reinforce the occupancy limits you set in the property description section, so the whole document stays consistent instead of contradicting itself in different places.
8. Explain Landlord Entry and Access
Most states set a notice period before a landlord can enter an occupied unit for repairs or inspections. Write your standard notice period in the lease, along with the exceptions for emergencies. Twenty-four hours' written notice is common practice nationwide.
Naming an exact notice period protects the tenant's right to quiet enjoyment while providing you with a documented process for scheduling repairs or showings.
9. Set Renewal, Termination, and Move-Out Terms
Add a renewal clause stating whether the lease auto-renews, converts to month-to-month, or ends on the term date. Explain the notice that either party must give to end the tenancy, and describe move-out expectations, such as cleaning and key return.
If a tenant breaks the lease early or you need to end a tenancy for cause, a documented lease termination letter keeps the process defensible. Clear termination language, written before anyone signs, saves both sides from having to guess later.
10. Add Required Disclosures and Lease Addenda
Federal and state law require certain disclosures in every lease. The Fair Housing Act protects tenants against discrimination based on race, color, religion, sex, national origin, familial status, and disability, so your lease and application process need to reflect that consistently.
Check your state's landlord-tenant law for required disclosures, such as lead paint notices for older buildings or mold disclosures in certain states. Landlord disclosures vary widely by state, so this is not a section to copy from a generic template. Attach any lease addendum you need for pets, parking, or special property rules rather than cramming extra terms into the main body.
11. Review the Lease for Clarity and Legal Compliance
Read the full document out loud before you send it, and rewrite any clause that could be read two different ways. A basic lease usually doesn't need a lawyer, but bring in a real estate lawyer for a long-term lease, several tenants, or complex state landlord-tenant law. If you add a custom clause outside a standard template, have a lawyer confirm it's enforceable first.
Lease Agreement Checklist Before Signing
12. Sign the Lease and Give Each Party a Copy
Once all clauses are confirmed, proceed to the lease signing process. Every adult tenant and the landlord (or an authorized agent) should sign and date the document, and each party should walk away with a copy, whether printed or digital.
We recommend electronic signature tools for this step. They timestamp the signature, store the document securely, and eliminate the back-and-forth of printing and scanning.
Making a lease legally binding takes three things: clear terms, a signature from every named party, and compliance with your state's disclosure rules.
What Should a Lease Agreement Include?
At a minimum, five things should be included in a lease: the parties, the property, the rent, the term, and the rules. Knowing what to include in a lease comes down to a short list of essential clauses. Use this as a quick reference while you draft.
Common Lease Agreement Clauses Landlords Should Understand
A few clauses cause more confusion than the rest of the document combined. Here's what each one actually does.
Joint and Several Liability
When multiple tenants sign a lease, joint and several liability means each tenant is responsible for the full rent, not just their share. If one roommate stops paying, you can pursue any or all of the remaining tenants for the balance.
Early Termination
An early termination clause states the penalty or process for a tenant who needs to leave before the lease ends, such as forfeiting the deposit or paying a set number of months' rent. Without this clause, the state's default rules determine the outcome, and they don't always favor the landlord.
Subletting and Assignment
This clause states whether a tenant can bring in a new occupant to take over the lease and whether you must approve that person first. Most landlords require written approval to screen any replacement tenant the same way they screened the original tenant.
Property Damage and Alterations
Spell out what counts as normal wear and tear versus damage the tenant pays for, and whether tenants can paint or make changes to the unit. This clause is what your deposit deduction process leans on if a dispute goes to small claims court.
Lease Renewal and Holdover
A lease renewal clause states what happens when the term ends: automatic renewal, conversion to a month-to-month, or a required new agreement. A holdover clause covers what happens if a tenant stays past the end date without signing a renewal, which usually triggers a higher rent rate or month-to-month terms by default.
Governing Law clause
A governing law clause names the state whose law applies to the lease, meaning which state's rules a court uses to interpret it. That's almost always where the property sits, not where the landlord lives, a common point of confusion. Disputes go to that state's courts. Any clause that conflicts with state law won't hold up, even if signed.
Common Lease Agreement Mistakes to Avoid
The most common mistakes come from copying a simple lease agreement template without adjusting it for your state or property. A few specific errors show up again and again:
- Using a generic template that skips required state disclosures
- Leaving the late fee or grace period undefined, which some states won't enforce without specifics
- Forgetting to name every adult occupant, which weakens your ability to collect rent from all of them
- Skipping the pet addendum, then trying to enforce pet rules that were never written down
- Reusing an old lease for a new property without updating the address and terms
Any one of these gaps can turn a routine tenancy into a legal headache. A quick pass through the checklist above catches most of them before you ever send the lease.
Conclusion
Writing a lease agreement means covering every clause in order and matching it to your state's rules. A state-specific lease agreement, built from a lease agreement checklist, protects your rent income and keeps you compliant with the Fair Housing Act and local landlord-tenant law. LeaseRunner is built around this process, so landlords can create, sign, and store a lease without hunting for the right clause
FAQs
What are the most important things to include in a lease?
Names of every tenant, the property description, rent and due date, security deposit terms, maintenance duties, entry notice, and any state-required disclosures. Leaving out any one of these is where most disputes start.
Can I change a lease agreement after it is signed?
Only if both parties agree in writing. A signed lease is a binding contract, so changes require a written amendment or addendum signed by the landlord and every tenant, not a verbal agreement or a text message.
What are red flags in a lease agreement?
Watch for vague late-fee language, no stated notice period for entry, missing security-deposit return terms, or a lease that skips required state disclosures entirely. Any of these should be fixed before either party signs.
