What must be included in a residential lease agreement?

A residential lease must include: full legal names of all parties, property address, lease term (start and end dates), monthly rent amount and due date, security deposit amount and terms, late fee policy, utilities responsibility, pet policy, maintenance obligations, entry notice requirements, and renewal/termination terms. Many states require additional disclosures such as lead paint, mold, and flood zone notices.

Can a landlord add any clause to a lease?

No. Lease clauses must comply with state and local law. Clauses that waive a tenant's statutory rights (such as the right to a habitable unit), impose illegal fees, discriminate based on protected characteristics, or violate local ordinances are unenforceable — even if both parties signed the lease.

Is a verbal lease agreement enforceable?

In most states, verbal leases are technically enforceable for tenancies of one year or less, but they create enormous evidentiary problems. Month-to-month verbal agreements are recognized in most jurisdictions, but any dispute about terms becomes a credibility contest with no documentary evidence. Always use a written lease.

Intelligent Landlord – Free Rental Property Intelligence

Your lease is your primary legal protection. It defines the relationship, establishes the rules, and determines what you can enforce and what you cannot. A generic online template downloaded in 2019 may be missing required 2026 disclosures, use clauses that courts have deemed unenforceable, or fail to address situations that end up costing landlords thousands.

This guide covers every essential clause — what it needs to say, why it matters, and the most common mistakes that make clauses unenforceable even after both parties sign.

"Most lease disputes aren't about what's clearly in the lease — they're about what's ambiguous, missing, or legally void. The lease you use determines the disputes you have."

The 18 Essential Clauses

Required in all states

Parties — Full Legal Names of All Tenants

Every adult who will occupy the unit must be named as a tenant on the lease. This is not optional. An unnamed adult occupant is not bound by the lease terms, cannot be held liable for rent, and may complicate the eviction process — you're evicting the named tenant but the unnamed adult has no obligation to leave under your eviction order in many jurisdictions.

Listing one name when two adults will live there. If the unlisted partner stays after the named tenant leaves, you may need a separate eviction proceeding.

Required in all states

Property Address and Description

Full legal address of the rental unit, including unit number. For properties with multiple units, specify which unit clearly. This seems obvious — but vague descriptions create jurisdiction and identification problems if you ever file an eviction complaint.

Required in all states

Lease Term — Exact Start and End Dates

Specify the exact start date and end date. "One year" is insufficient — courts need a fixed date to determine when the tenancy expires, when cure periods run, and whether a holdover has occurred. Also specify what happens at the end of the term: does it auto-convert to month-to-month, or does the tenant need to vacate?

Month-to-month conversion language that's missing or ambiguous. Many landlords discover they've inadvertently created a month-to-month tenancy requiring 30+ days' notice they didn't anticipate.

Required in all states

Rent Amount, Due Date, and Payment Method

Specify the exact monthly rent, the day it's due (typically the 1st), and the grace period if any. Specify acceptable payment methods — check, bank transfer, online portal, money order. Note: if you accept cash, document every payment receipt. If you don't want cash, say so. Many states allow landlords to prohibit cash payments in writing.

Required in all states

Late Fees — Amount, Trigger Date, and Limits

Most states cap late fees — commonly $50–$100 or 5–10% of rent. The lease must specify the exact fee amount, the day it triggers (e.g., after the 5th of the month), and whether it's a flat fee or daily. A late fee clause that exceeds state limits is unenforceable in full in some states — not just the excess portion.

Setting a late fee of $150/day for a $1,500/month unit in a state that caps fees at $50 total. Courts void the clause entirely, leaving you with no late fee protection.

Required in all states

Security Deposit Terms

Amount, how it's held (separate account or commingled — many states require separate), the address of the bank (some states require disclosure), interest (some states require), conditions for deduction, and the return timeline. California's 2024 cap of one month must be reflected if applicable. See our full Security Deposit Guide for state-specific requirements.

Required in all states

Occupancy Limits and Authorized Occupants

Specify who may reside in the unit. Fair Housing law limits how you can set occupancy limits — HUD's general guideline is two people per bedroom as a starting point, but local fire codes, the specific unit size, and other factors matter. Specify that overnight guests staying more than X consecutive days (typically 7–14) constitute unauthorized occupants. This is your mechanism for controlling subletting and Airbnb use.

Required in all states

Utilities — Who Pays What

Explicitly list every utility and specify who is responsible: electric, gas, water, sewer, trash, internet, cable. "Tenant pays all utilities" is ambiguous if the city bills water to the property owner — specify whether you pass through water billing and how. Vague utility clauses create billing disputes that are difficult to resolve.

Required in all states

Maintenance Obligations

State who is responsible for what. The landlord maintains the structure, systems, and appliances. The tenant is responsible for keeping the unit clean, disposing of trash, not causing damage, and promptly reporting maintenance issues. Specify the required notice method for repair requests (text, email, written) and the tenant's obligation to allow access for repairs. A tenant who fails to report a known issue causing further damage may share liability — but only if your lease creates that obligation.

Required in all states

Landlord Entry Rights and Notice Requirements

Most states require 24–48 hours written notice before landlord entry for non-emergency reasons. Your lease must reflect the statutory minimum for your state — you cannot contract around it. Specify: notice period, acceptable notice methods, and emergency entry rights (no notice required for true emergencies). Entering without proper notice is a habitability violation in many states and can trigger rent withholding rights.

Varies by state

Pet Policy

Specify whether pets are allowed, what types (species, breed restrictions), maximum weight, and whether a pet deposit or monthly pet fee applies. Note: emotional support animals (ESAs) and service animals are not "pets" under Fair Housing law — you cannot charge a pet deposit for them or prohibit them via a no-pet clause. Handle ESA requests through the reasonable accommodation process, not the pet clause.

Breed restriction clauses that apply to ESAs or service animals. This is a Fair Housing violation regardless of what your lease says.

Required in most states

Smoking and Drug Policy

Specify whether smoking (tobacco, cannabis, vaping) is permitted inside the unit, on the premises, within a certain distance of the building. Many states now require explicit cannabis policies in leases. A blanket no-smoking clause that doesn't address cannabis may not prohibit cannabis smoking in states where it's legal. Be specific about each substance and location.

Required in most states

Subletting and Airbnb Prohibition

Explicitly prohibit subletting, assignment of the lease, and short-term rental use (Airbnb, VRBO, etc.) without written landlord consent. Without an explicit prohibition, some states default to allowing subletting. Specify that unauthorized subletting or short-term rental is a material lease violation subject to the cure-or-quit notice process.

Federal requirement

Lead Paint Disclosure (Pre-1978 Properties)

Federal law (TSCA Title X / HUD/EPA rule) requires landlords of pre-1978 housing to: disclose known lead paint hazards, provide the EPA's "Protect Your Family" pamphlet, and include a specific disclosure clause in the lease with tenant signature. Failure to comply carries civil penalties up to $19,507 per violation and criminal penalties up to $25,000/day. This is not optional and is often missing from generic templates.

Using a template that lacks the federally required lead paint disclosure addendum. Every pre-1978 property needs this — regardless of whether you've tested for lead.

Recommended for all states

Renter's Insurance Requirement

Require tenants to carry renter's insurance with minimum coverage ($100K liability, $15K–$25K personal property) and name the landlord as an additional interested party. Request proof at move-in and annually. This reduces your liability exposure significantly and the cost to tenants ($15–$30/month) is negligible.

Recommended for all states

Attorney's Fees Clause

In states that allow it, include a mutual attorney's fees clause — the prevailing party in a dispute is entitled to attorney's fees. This deters frivolous claims from both sides and is particularly useful in eviction proceedings where tenant delay is the strategy. Note: some states (California) impose one-sided attorney's fees clauses by statute; check your state's law before adding this.

Recommended for all states

Move-In Condition Checklist Incorporation

Reference and attach a move-in checklist signed by both parties as an exhibit to the lease. This makes the baseline condition documentation part of the contract — establishing the legal standard against which move-out condition is measured. Without this, any repair cost dispute starts from zero.

State-Specific

Required State Disclosures (Varies Widely)

Many states require specific lease addenda: mold disclosure (CA, TX, WA), flood zone disclosure (CA), bed bug disclosure (NY), domestic violence protections (many states), right to repair (CA), utility billing methodology disclosure, and more. Your lease template must include every disclosure required by your state and municipality — generic national templates often miss state-specific requirements entirely.

Using a national template in California without the AB 1482 just-cause eviction addendum, bed bug disclosure, or mold/mildew disclosure — all required.

Clauses Courts Routinely Void

These clauses appear in landlord leases regularly and are routinely unenforceable. Signing doesn't save them.

Clause	Why It's Void	What to Do Instead
"Tenant waives right to habitable unit"	Statutory right — cannot be waived by contract	Maintain habitability; address repairs promptly
"Landlord not liable for any damage"	Overbroad; doesn't eliminate negligence liability	Require renter's insurance; use specific limitation language
"Tenant pays attorney fees regardless of outcome"	Many states require mutual or prohibit one-sided clauses	Use a mutual attorney's fees clause or check state law
"No guests ever"	Courts routinely void absolute guest prohibitions	Limit consecutive overnight stays to 7–14 days
"$200/day late fee"	Exceeds state caps; courts void entire clause	Use state-compliant flat fee within the legal cap
"Tenant responsible for all repairs"	Landlord cannot contract away habitability obligations	Assign routine maintenance; retain structural/system responsibility
"No ESAs or service animals"	Federal Fair Housing violation — cannot enforce	Address ESAs through reasonable accommodation process

State-Specific Addenda You Probably Need

In addition to the core lease, many states require separate addenda. These are the most commonly missed:

California: AB 1482 just-cause addendum, mold/mildew disclosure, flood zone disclosure, bed bug disclosure, utility rate disclosure, move-out notice requirements
New York: Bed bug disclosure, NYC-specific rider (for NYC properties), lead paint (pre-1978), ETPA/HSTPA riders for stabilized units
Texas: Mold disclosure, smoke detector notice, security device notice, lead paint (pre-1978)
Washington: Mold disclosure, lead paint (pre-1978), move-in checklist (required by statute)
Illinois: Chicago RLTO addendum for Chicago properties, radon disclosure (for certain units)
Florida: Radon gas disclosure (required statewide)

Annual review

Lease requirements change as state legislatures update landlord-tenant law. Review your lease template against your state's current statutes at least annually — and any time there's a major legislative session. Statutes from our state law pages are updated regularly for exactly this reason.

The Bottom Line

A well-drafted lease prevents most disputes before they start. Every clause must accurately reflect your state's current law, be specific rather than vague, and avoid provisions courts have established as unenforceable. Review your current lease against this framework — then have a landlord-tenant attorney in your state review the result before you use it.
