How to Write a Lease Agreement: A First-Time Landlord's Checklist
A lease is your most important legal document as a landlord. Here's what every first-time landlord needs to include — and the mistakes that will cost you later.
Your lease is the most important document in your landlord business. Not your mortgage. Not your insurance. Your lease. It defines the rules before anyone moves in, protects you when something goes wrong, and - when it’s written well - prevents most disputes from becoming legal problems.
Most first-time landlords underestimate this document. Don’t be one of them.
What you’ll learn:
- Why a generic lease template will get you in trouble
- The 9 things every lease must cover
- What to leave out (and why it matters)
- What to do the day the lease gets signed
Why can’t I just use a free template I found online?
You can use a template as a starting point - but most free generic templates don’t comply with your specific state’s requirements. Landlord-tenant law varies significantly by state. Security deposit limits, required disclosures, notice periods, and eviction procedures are all state-specific. A clause that’s perfectly legal in Texas may violate tenant rights in California.
Use a state-specific template from a reputable source. Avail, TurboTenant, and RocketLawyer all offer state-specific residential lease templates that are worth the small cost. For your first lease, seriously consider having a local real estate attorney review it - a one-time cost of $150-$300 that prevents the kind of mistakes that show up two years later during an eviction.
What does every lease need to include?
1. Who and where
List the full legal name of every adult who will live in the unit. If you put one name on the lease and two people are living there, the unnamed person has zero legal obligation to you. Include your full legal name (or your LLC name if you own through an entity) and the complete address of the rental, including unit number.
2. Lease term
State the exact start and end date for a fixed-term lease. Include what happens when it ends - does it automatically convert to month-to-month, or must the tenant vacate? If it starts as month-to-month, say so explicitly and specify the required notice to terminate (typically 30 days from either party).
3. Rent, due date, and late fees
State the monthly rent amount, the due date (the 1st is standard), any grace period, and the late fee amount and trigger date. Before you write this section, check your state’s rules on late fees - many states cap them at a percentage of monthly rent or a flat dollar amount. A late fee that exceeds the legal cap is unenforceable.
4. Security deposit
State the amount, where it will be held, and the conditions under which you can make deductions. Some states require a separate bank account for security deposits and mandate interest payments. Look this up before you draft the section. Include the return timeline too - state law dictates this (typically 14-45 days), and your lease can’t override it.
5. Utility responsibilities
List every utility and assign it clearly: electricity, gas, water, sewer, trash, internet. “Tenant pays all utilities” is not specific enough. Name each one. Ambiguity here is how you end up arguing over a $200 water bill two years from now.
6. Required legal disclosures
Federal law requires a lead-based paint disclosure for any property built before 1978. That one is non-negotiable. State requirements vary and commonly include mold history, bed bug history, flood zone status, and environmental hazard disclosures. Look up your state’s required landlord disclosures before you finalize anything.
7. Maintenance responsibilities
Put in writing who handles what. Tenants are typically responsible for keeping the unit clean, disposing of trash, reporting issues promptly, and not damaging the property. You’re responsible for maintaining habitable conditions, working heat and hot water, structural repairs, and code compliance. Include your notice requirement before entering - most states mandate 24-48 hours. Put the exact period in the lease.
8. Pets, smoking, and subletting
State your policy on all three, explicitly. For pets: whether they’re allowed, any deposit or monthly pet rent, and any size or number restrictions. Note that emotional support animals are not pets under fair housing law and cannot be refused on the same grounds. For smoking: “no smoking anywhere on the property” is the cleanest and most enforceable policy. For subletting: prohibit it without prior written approval. Otherwise, you may find your unit listed on Airbnb without your knowledge.
9. Termination and notice
For month-to-month tenancies, state the required notice period to terminate (typically 30 days, but verify your state - some require 60). Reference the legal eviction process rather than trying to write your own. State law governs evictions completely. Any lease provision that contradicts it won’t hold up.
What should I leave out of my lease?
Don’t include clauses that waive tenant rights, exceed legal security deposit limits, or shift your legal responsibilities onto the tenant. Those provisions are unenforceable - and in some states, including them can expose you to fines or penalties even if the tenant never challenges them.
Don’t write a lease that reads like a threat list. Clear, neutral, professional language sets a better tone for the relationship and is easier to enforce. You want tenants to understand what they signed, not resent it before they unpack a box.
What do I do after we both sign?
Give every adult tenant a signed copy immediately. Some states legally require this within a certain number of days. Keep a signed original yourself - scanned PDF in cloud storage is fine.
Do a written move-in inspection before handing over the keys. Walk every room with the tenant, note any existing damage, take photos, and have both of you sign it. This document is what stands between you and a “but it was like that when I moved in” dispute at move-out.
A solid lease won’t prevent every problem. But it gives you a clear framework when problems happen - and they will. Get it right before anyone signs.
Frequently Asked Questions
Can I use a free lease template from the internet?
You can use a template as a starting point, but free generic templates rarely comply with your state's specific requirements. At minimum, verify that any template you use includes your state's required disclosures and does not contain any provisions that violate local landlord-tenant law. Services like Avail, TurboTenant, and RocketLawyer offer state-specific lease templates that are more reliable.
Do I need a lawyer to write a lease?
You do not need a lawyer for a straightforward residential lease, but it is worth having one reviewed by a local real estate attorney at least once — especially for your first lease. The cost is typically $150–$300 and can prevent expensive mistakes.
What happens if I forget to include something in the lease?
State law fills most gaps. If your lease is silent on a topic, your state's default landlord-tenant rules apply. This is not ideal — you want the lease to be explicit — but it is not a disaster. The exception is required disclosures: failing to include federally or state-required disclosures can create legal liability.
Can I change the lease after both parties sign it?
Only by written mutual agreement — a lease addendum signed by both the landlord and all tenants. You cannot unilaterally change terms during an active lease.
What is the difference between a lease and a rental agreement?
A lease is typically a fixed-term contract (commonly 12 months) that cannot be changed mid-term by either party. A rental agreement is usually month-to-month, with more flexibility for both parties to give notice and terminate. Both are legally binding.
