The common landlord and tenant disputes cluster around a short list of problems: unpaid rent, repairs the landlord won’t make, security deposits the landlord won’t return, discrimination, retaliation against a tenant who complained, illegal lockouts, and lease breaks. Each one has its own rules and its own process, and the side with better documentation and the correct paperwork almost always wins. Your lease is the starting point, but federal and state law layer protections on top of whatever the contract says.
Unpaid Rent and Other Lease Violations
Nonpayment of rent is what starts most eviction cases. When rent goes past any grace period the lease or local law provides, the landlord can begin the formal process. Grace periods typically run from three to fourteen days, and some states don’t require one at all. What controls is the lease term or the local ordinance, not the landlord’s patience.
Other violations trigger disputes too. An unauthorized pet, a sublet without permission, or too many people in the unit can all give a landlord grounds to demand compliance or move toward eviction. These feel minor to a tenant and serious to an owner. In most jurisdictions the landlord has to serve a written notice that names the specific violation and gives the tenant a set number of days to cure it before filing anything in court.
Repairs and Habitability
The implied warranty of habitability exists in most states and requires landlords to keep rental units fit to live in. That means working plumbing, adequate heat, a sound roof, and no serious health hazards like mold or pests. You don’t need a specific lease clause for this to apply. If conditions slide into unsafe territory, you have options.
“Repair and deduct” is allowed in roughly half of states in some form. You notify the landlord in writing, give them a reasonable time to fix the problem, and if they don’t, you hire someone, make the repair, and subtract the cost from your next rent payment. Keep every receipt and a copy of your written notice. The remedy is limited to genuine health and safety issues, not cosmetic ones.
Rent withholding is another route in many jurisdictions. Some states let you deposit rent into a court-controlled escrow account until repairs are made. Simply stopping payment and pointing to habitability problems is risky. Courts are far more sympathetic to a tenant who parked the money in escrow than one who just quit paying.
In an extreme case, a tenant may claim constructive eviction, meaning the conditions were bad enough to force them out. To make that stick you generally have to show you notified the landlord, gave reasonable time to fix things, and then actually moved. You can’t claim constructive eviction while still living in the unit.
Security Deposit Disputes
Deposit fights are among the most frequent conflicts, and they show up at the end of a tenancy. Landlords can deduct for damage beyond normal wear and tear, like large holes in walls, broken fixtures, or heavily stained carpets. They cannot deduct for ordinary deterioration such as minor scuff marks, faded paint, or lightly worn carpet.
Every state sets a deadline for returning the deposit, ranging from ten to sixty days, with most falling in the fourteen-to-thirty-day window. The landlord is typically required to include an itemized list of deductions along with any remaining balance. Skipping the itemization or returning the deposit late can expose the landlord to penalties, and some states let the tenant recover double or triple the amount wrongfully withheld.
The best defense against a deposit fight is a thorough move-in and move-out inspection. Walk through together at the start and end of the lease, photograph and video every room, and keep a written checklist. Even where a joint inspection isn’t required by law, doing one is the single most effective way to prevent a dispute.
Fair Housing and Discrimination
The federal Fair Housing Act prohibits landlords from discriminating based on race, color, religion, sex, national origin, familial status, or disability. Discrimination isn’t limited to an outright refusal to rent. It also covers different lease terms, inferior services, steering tenants toward certain units or neighborhoods, and ads that state a preference based on a protected characteristic.1Office of the Law Revision Counsel. 42 USC 3604 – Discrimination in the Sale or Rental of Housing and Other Prohibited Practices Many state and local laws add protected categories such as source of income, sexual orientation, or immigration status.
Disability protections are especially detailed. Landlords must allow tenants with disabilities to make reasonable modifications at their own expense, such as installing grab bars or widening doorways. They must also make reasonable accommodations in rules, policies, and services when necessary to give a person with a disability equal opportunity to use and enjoy their home.1Office of the Law Revision Counsel. 42 USC 3604 – Discrimination in the Sale or Rental of Housing and Other Prohibited Practices
Assistance Animals and Emotional Support Animals
Under HUD guidance, emotional support animals are classified as assistance animals, not pets. A landlord with a no-pet policy must still allow an assistance animal as a reasonable accommodation for a tenant with a disability. The landlord cannot charge pet fees, pet deposits, or additional rent for the animal.2U.S. Department of Housing and Urban Development. Fact Sheet on HUD’s Assistance Animals Notice
If the disability and need for the animal aren’t obvious, the landlord can ask for documentation from a licensed healthcare professional confirming the disability and the therapeutic need. The landlord cannot demand medical records or a specific diagnosis. HUD has warned that certificates purchased from online registries that sell documentation to anyone who pays are generally not considered reliable proof.2U.S. Department of Housing and Urban Development. Fact Sheet on HUD’s Assistance Animals Notice A landlord can deny a request only if the animal poses a direct, documented threat to safety or would cause significant property damage that can’t be reduced through another accommodation.
Filing a Fair Housing Complaint
If you believe a landlord discriminated against you, you can file a complaint with HUD within one year of the last discriminatory act.3Office of the Law Revision Counsel. 42 USC 3610 – Administrative Enforcement; Preliminary Matters HUD must complete its investigation within 100 days where possible and will try to resolve the matter through a voluntary agreement between the parties. If conciliation fails and HUD finds reasonable cause, the case can go to a HUD administrative law judge or be referred to federal court. Remedies include compensation for actual damages, emotional distress, injunctive relief, and civil penalties.4U.S. Department of Housing and Urban Development.

Retaliation After a Complaint
Most states prohibit landlords from retaliating against tenants who exercise legal rights. Protected activities generally include reporting code violations to a government agency, requesting legally required repairs, organizing with other tenants, or testifying in a housing proceeding. If a landlord raises the rent, cuts services, or files for eviction shortly after one of these activities, the law may presume a retaliatory motive.
The presumption kicks in when the landlord acts within a set window after the protected activity, often six months to one year. Once you establish the timing, the burden shifts to the landlord to prove a legitimate, non-retaliatory reason. If they can’t, you may be entitled to stay, recover damages, and in some states collect a penalty equal to several months’ rent plus attorney’s fees.
The defense has limits. It generally won’t help if your rent was already behind before you complained, or if the landlord started the eviction before your protected activity. It also usually can’t be used repeatedly by the same tenant in a short period.
Illegal Lockouts and Utility Shutoffs
Every state requires landlords to use the court process to remove a tenant. A landlord who changes your locks, shuts off your utilities, removes your belongings, or otherwise tries to force you out without a court order is committing an illegal self-help eviction. That’s true even if you owe months of back rent or have clearly broken the lease.
If a landlord locks you out or cuts off water or electricity, contact local law enforcement and seek legal help. Tenants who are illegally locked out can typically recover damages, get a court order restoring access, and in some jurisdictions collect statutory penalties. Landlords who take matters into their own hands frequently end up worse off than if they had filed the eviction properly.
Breaking a Lease Early
When a tenant leaves before the lease ends, what they owe depends heavily on whether the landlord tries to re-rent the unit. A majority of states impose a duty to mitigate damages, meaning the landlord must make a reasonable, good-faith effort to find a replacement tenant instead of leaving the unit empty and billing you for the balance of the term. If the unit is re-rented, your exposure drops to the gap between when you left and when the new tenant’s payments begin, plus any reasonable re-rental costs.
Early termination clauses matter. Some leases include a buyout provision that lets you end the lease by paying a set fee, often one or two months’ rent. If your lease has that language, it typically caps your liability. If it doesn’t, your exposure depends on state law and the landlord’s mitigation efforts.
Military Servicemembers
Federal law gives military servicemembers a specific right to end a residential lease early. Under the Servicemembers Civil Relief Act, you can terminate without penalty if you receive permanent change of station orders, deployment orders for 90 days or more, or certain stop-movement orders. Termination requires delivering written notice along with a copy of your military orders to the landlord. You can deliver notice by hand, mail with return receipt, private carrier, or electronic means.5Office of the Law Revision Counsel. 50 USC 3955 – Termination of Residential or Motor Vehicle Leases Any lease provision that tries to waive this right is unenforceable.
Documenting Your Case
When a dispute heads toward legal action, the side with better records wins far more often than the side with the better story. Start with the signed lease. Every claim about what the other party did wrong needs to trace back to a specific clause or a specific law. If you can’t point to either, your argument weakens.
Financial records are the backbone of rent disputes. Keep copies of every payment, whether through bank statements, checks, electronic transfer confirmations, or receipts. If there’s a fight about how much was paid and when, the party with clear records controls the narrative.
Photographs and video at move-in and move-out are critical for deposit disputes. Capture every room, every appliance, and any existing damage at the start of the tenancy, and repeat the process on the way out. Make sure images have timestamps. A photo showing a stained carpet on the day you moved in is worth more than any amount of later testimony.
Keep a written log of every interaction with the other party. Save emails and text messages. For phone calls and in-person conversations, write a dated note summarizing what was discussed immediately afterward. Courts pay close attention to whether a party made a good-faith effort to resolve the issue before filing, and a communication trail shows exactly that.
Written Notice Before Filing
Almost every jurisdiction requires a written notice before a landlord files an eviction or a tenant pursues certain remedies. The notice must identify the parties by their full legal names as shown on the lease, list the property address including unit number, and describe the exact problem. For unpaid rent, that means the precise amount owed, including any late fees the lease allows. For a lease violation, it means identifying the specific clause that was breached.
The notice must give the other party a deadline to respond or cure. For nonpayment of rent, most states require somewhere between three and fourteen days. For other violations, the cure period is often longer. Getting the timeline wrong can invalidate the notice and force the landlord to start over. The clock runs from proper delivery, not from the date on the letter.
Deliver the notice in a way that creates proof of receipt: certified mail with return receipt, or personal delivery witnessed by a third party. Many courts and housing authorities publish template forms for common notices, and using an official template reduces the risk of missing a required element.
Court, Mediation, and What Comes After
Most landlord-tenant cases end up in small claims court or a specialized housing court. Filing requires paperwork submitted to the clerk of court and a filing fee that varies by jurisdiction and by the amount in dispute. Once a case number is assigned, the other party must be served through a neutral third party such as a process server or sheriff’s deputy, and proof of service goes back to the court. Without that proof, the case cannot move forward.
Many courts now offer or require mediation before trial. A neutral third party helps both sides negotiate a resolution such as a payment plan, a repair schedule, a lease modification, or a structured move-out. The mediator doesn’t impose a decision, so any agreement is one both sides accept. Mediation is faster, less expensive, and confidential, and it allows for creative solutions a judge can’t order. If it fails, the case moves on to trial anyway.
Winning a judgment isn’t the same as collecting. If a court awards a landlord unpaid rent and the tenant doesn’t pay voluntarily, the landlord has to pursue enforcement. Wage garnishment is one common tool. Federal law caps garnishment for ordinary debts at 25% of disposable earnings or the amount by which weekly earnings exceed 30 times the federal minimum wage, whichever produces the smaller figure.6Office of the Law Revision Counsel. 15 USC 1673 – Restriction on Garnishment Bank levies and property liens are other options depending on jurisdiction. If the judgment grants possession and the tenant refuses to leave, the landlord obtains a writ of possession and law enforcement carries out the removal. Even at this stage, the landlord cannot handle it personally.
Eviction Records
An eviction judgment creates a public court record that can follow you for years. Under the Fair Credit Reporting Act, consumer reporting agencies can include civil judgments on credit reports for up to seven years from the date of entry.7Office of the Law Revision Counsel. 15 USC 1681c – Requirements Relating to Information Contained in Consumer Reports Tenant screening companies search court records for eviction filings, and some report cases even when the landlord lost or the case was dismissed. Simply being named in an eviction action, regardless of outcome, can make future renting harder.
Some jurisdictions have started sealing eviction records after a dismissal or a tenant-favorable decision, and a few restrict how far back screening companies can look. Under current federal law, the seven-year window remains the baseline.7Office of the Law Revision Counsel. 15 USC 1681c – Requirements Relating to Information Contained in Consumer Reports For tenants, that’s a reason to fight or settle a weak case before a judgment lands on your record.
Belongings Left Behind
When a tenant moves out or is evicted and leaves belongings behind, the landlord cannot simply throw everything away. Most states require the landlord to notify the former tenant, store the property for a set period, and give the tenant a chance to reclaim it. Storage periods vary, and thirty days is a common benchmark. Perishable items and obvious garbage can usually be discarded, but anything of apparent value has to be kept safe. Landlords who skip these steps risk liability for the value of what they destroyed.
