What Are the Legal Grounds for Evicting a Tenant?

You can evict a tenant only for a reason the law recognizes: unpaid rent, a lease violation, illegal activity on the property, serious damage or nuisance, or staying after the tenancy has legally ended. Where a just-cause law applies, such as California's Tenant Protection Act or New York's Good Cause Eviction Law, you also need a listed reason to end a tenancy that has no fixed end, and some no-fault reasons require paying the tenant. Retaliation and discrimination are never legal grounds. Written notice is usually required before you file in court, and a notice with the wrong form, amount, or deadline can get the case dismissed.

What are the legal reasons to evict, and which notice does each need?

Each state sets its own rules for when notice is required. California and Florida show how the notice changes with the reason:

In New York, a nonpayment case requires a 14-day written rent demand first. For a tenancy covered by the Good Cause Eviction Law, a lease violation requires a written notice giving the tenant 10 days to fix it.

The notice must match the ground. In California, a pay-or-quit notice can demand only rent, not late fees, utilities, or damages. Florida treats a repeat of the same violation within 12 months of a written warning as one the tenant gets no chance to cure. Sending a warning notice explains how a warning letter fits before the formal notice.

When do you need just cause, and what counts?

Florida has no statewide just-cause rule: either side can end a month-to-month tenancy with 30 days' written notice without stating a reason. California and New York require a reason in many cases.

California. The Tenant Protection Act requires just cause once a tenant has lived in the unit for 12 months. It covers most apartment buildings with two or more units that are at least 15 years old. An owner-occupied duplex is exempt only if the owner has continuously lived in one unit as their principal residence since the tenancy began. Many single-family homes and condos are exempt only if the tenant receives the required written exemption notice, which must be in the rental agreement for tenancies begun or renewed on or after July 1, 2020. The law lists two kinds of causes:

• At fault: nonpayment, breaking a material lease term, an unauthorized sublet, criminal activity, nuisance or serious damage, refusing lawful entry, or refusing to sign a renewal on similar terms. If the problem can be fixed, you must first give a notice with a chance to fix it; only if the tenant does not fix it can you serve a 3-day notice ending the tenancy, and then file.

• No fault: you or a qualifying family member will move in, you are taking the unit off the rental market, a government order requires the tenant to leave, or you will demolish or substantially remodel. No-fault terminations carry extra conditions, and a notice that does not strictly follow them is void:

• Relocation help. Pay the tenant one month's rent within 15 calendar days of serving the notice, or waive the final month's rent. The notice must state the no-fault reason and which option you chose.

• Owner move-in. The owner or relative must move in within 90 days after the tenant leaves and live there as a primary residence for at least 12 consecutive months. For tenancies started or renewed on or after July 1, 2020, the lease must allow this termination or the tenant must agree in writing, and the ground is unavailable if a similar unit on the property is vacant.

• Substantial remodel. The work must replace or substantially change a structural, electrical, plumbing, or mechanical system under a permit, or remove hazardous materials, and keep the tenant out for at least 30 consecutive days. Cosmetic work does not qualify, and the notice must include a copy of the permits.

Many California cities have stricter local just-cause and relocation rules. California's eviction process covers the state steps in detail.

New York. The Good Cause Eviction Law applies in New York City and in localities that opt in. The Attorney General's list includes Albany, Binghamton, Catskill, Croton-on-Hudson, Fishkill, Hudson, Ithaca, Kingston, Newburgh, New Paltz, Nyack, Poughkeepsie, and Rochester, among others, and more may join, so check with your city or village. In New York City, the law does not apply to a small landlord, one who owns 10 or fewer units in the state, or to an owner-occupied building with 10 or fewer units. Localities that opt in can set their own small-landlord and high-rent exemption limits, so read your local law before relying on those exemptions. The owner-occupied exemption remains 10 or fewer units. Covered grounds include nonpayment (unless caused by an unreasonable rent increase), lease violations, nuisance, illegal use, refusing access for repairs, owner or family move-in (not available against a tenant who is 65 or older or disabled, or when another suitable unit in the building is available), demolition, leaving the rental market, and refusing a reasonable renewal offer.

Which reasons are illegal?

Retaliation. You cannot evict a tenant for exercising a legal right, such as complaining to a code inspector or joining a tenant group. The time window varies by state:

• California: an eviction within 6 months after the tenant used a protected right, such as repair and deduct or a code complaint, is presumed retaliatory if the tenant is not in default on rent. Other retaliation protections can still apply.
• New York: an eviction started within 1 year of a good-faith complaint is presumed retaliatory, and you must prove a non-retaliatory reason.
• Florida: the tenant can raise retaliation as a defense, but it fails if you prove good cause, such as nonpayment or a lease violation.

Discrimination. The federal Fair Housing Act bars making housing unavailable, or setting different terms, because of race, color, religion, sex, familial status, national origin, or disability. Ending a tenancy for one of those reasons is illegal even if the lease would otherwise allow it. State law can add classes; California also protects source of income (including housing vouchers), sexual orientation, marital status, and military or veteran status.

Self-help. Changing the locks, removing belongings, or shutting off utilities to force a tenant out is illegal in California and New York and exposes you to damages. Why you should not evict the tenant yourself covers the penalties.

Why does the notice decide the case?

When required, the termination notice is a condition of the lawsuit. California's court guide warns that a notice with mistakes or missing information can lose the case. Common defects include demanding the wrong amount, counting days incorrectly, leaving out a required just-cause statement, and serving the notice the wrong way. Florida judges must give you a chance to fix a defective notice before dismissing. In California, a case lost on a paperwork error usually means serving a corrected notice and filing again.

Two federal and rent rules can change the notice you serve:

• CARES Act 30-day notice. If the property has a federally backed mortgage (Fannie Mae, Freddie Mac, FHA, or USDA) or the tenant uses a federal housing program such as a Section 8 voucher, federal law requires 30 days' notice to vacate. Most courts have held this still applies to nonpayment evictions, according to a May 2026 Congressional Research Service report, though the Iowa Supreme Court ruled otherwise. California's court guide lists it as a separate notice type.
• Accepting rent. In Florida, accepting rent while knowing of a violation can waive your right to evict for that violation, and accepting partial rent after a 3-day notice requires a receipt with the agreed date, a deposit into the court registry, or a new notice. In California, accepting the full past-due rent after the 3-day period ends waives eviction for that late payment.

If nothing else works, should you file for eviction?

File when the ground is documented, any required notice period has run, and alternatives have failed. Eviction takes court fees and weeks of lost rent; California's court guide estimates 30 to 45 days or more from serving the court papers to move-out, with filing fees of $240 to $450. Before filing, compare that with a negotiated move-out date or a payment for the tenant to leave by a set date, described in making it easy for the tenant to leave voluntarily.

Only a court judgment and a sheriff or marshal can remove a tenant. Expect the tenant to raise defenses, especially retaliation or poor conditions, and gather your lease, ledger, notices, and repair records before you file. The steps for eviction proceedings walk through the case from filing to lockout, and general ways to end a tenancy agreement covers the non-court options.
