Under California Code of Civil Procedure Section 1161(4), a landlord can end a tenancy when a tenant commits a nuisance, uses the property for an unlawful purpose, causes serious damage, or sublets in violation of the lease. A nuisance eviction under CCP 1161(4) in California is incurable: the tenant does not get a chance to fix the behavior and stay. The landlord must still serve a written three-day notice to quit and, if the tenant doesn’t leave, win an unlawful detainer judgment in court before the sheriff can remove anyone.
What CCP 1161(4) Actually Covers
Subdivision 4 bundles together several serious lease violations that the statute treats as automatically terminating the tenancy. It applies when a tenant commits nuisance, uses the premises for an unlawful purpose, commits waste (significant damage beyond normal wear), or assigns or sublets contrary to the lease.1California Legislative Information. California Code of Civil Procedure CCP 1161 Because the tenant’s own conduct ends the lease, the landlord only has to serve a three-day notice demanding the tenant vacate. No pay-or-quit, no cure-or-quit.
The statute also carves out a “deemed nuisance” category. Certain conduct counts as nuisance per se for eviction purposes: maintaining a property for dogfighting or cockfighting under Civil Code 3482.8, and the offenses described in Civil Code Sections 3485 and 3486, which cover illegal drug activity and unlawful weapons or ammunition offenses.1California Legislative Information. California Code of Civil Procedure CCP 1161 For these, the landlord does not have to independently prove the behavior satisfies the general nuisance definition.
What Counts as Nuisance
CCP 1161(4) does not define nuisance. The definition comes from Civil Code Section 3479: anything harmful to health, including the illegal sale of controlled substances; anything indecent or offensive to the senses; or anything that obstructs the free use of property and interferes with the comfortable enjoyment of life or property.2California Legislative Information. California Civil Code 3479 It’s broad on purpose, and judges have substantial discretion in applying it.
The practical line is between annoyance and substantial interference. A single loud party rarely supports an eviction. Repeated behavior that makes neighboring units unlivable, or that creates real safety risks, is where these cases succeed. Courts look at severity, frequency, and impact.
Conduct landlords commonly pursue under this subdivision includes:
- Drug manufacturing, sale, or storage on the premises. California’s drug abatement statutes designate buildings used for these purposes as a nuisance.1California Legislative Information. California Code of Civil Procedure CCP 1161
- Violence, intimidation, or credible threats aimed at the landlord, property manager, or other tenants.
- Chronic excessive noise that goes well beyond ordinary living sounds and disrupts neighboring residents.
- Intentional destruction of the unit or common areas, which the statute separately labels waste.
- Ongoing criminal use of the rental, such as running an illegal business or harboring stolen property.
Evidence decides these cases. Vague complaints or a single incident often fail at trial. Police reports, dated written complaints from other tenants, photographs, and code enforcement records all strengthen the landlord’s position.
The Three-Day Notice to Quit
Before any lawsuit, the landlord must serve a written three-day notice to quit. For nuisance under CCP 1161(4), the notice demands only that the tenant vacate. There is no option to cure.1California Legislative Information. California Code of Civil Procedure CCP 1161
The notice should include the tenant’s full name, the property address, and a detailed description of the conduct that constitutes the nuisance, with specific dates and facts.3Judicial Branch of California. Types of Eviction Notices Boilerplate language like “you are creating a nuisance,” without supporting facts, is a frequent mistake and can sink the entire case.
How the Notice Must Be Served
CCP Section 1162 recognizes three ways to serve a residential tenant:4California Legislative Information. California Code of Civil Procedure CCP 1162
- Personal delivery to the tenant.
- Substituted service: leaving the notice with another adult at the tenant’s home or workplace, plus mailing a copy to the home.
- Post and mail: posting the notice in a visible place on the property and mailing a copy, used when no one can be found or served in person.
The three-day clock starts the day after service is complete, and courts may add time for mailing when post-and-mail service is used. Improper service is one of the most common tenant defenses, and shortcuts here often get a case dismissed before the merits are even reached.
Just Cause and the Tenant Protection Act
For tenancies covered by the Tenant Protection Act (Civil Code 1946.2), a landlord cannot terminate without “just cause” once the tenant has lived in the unit for at least 12 months. Nuisance under CCP 1161(4) is specifically listed as at-fault just cause, as are waste, criminal activity on the property, and unlawful use of the premises.5California Legislative Information. California Civil Code 1946.2
The practical effect is that the written notice must state the reason for the eviction. Vague notices with reasons added later do not satisfy the statute. The Tenant Protection Act applies to most residential rentals in California, with exceptions for certain single-family homes where the owner is not a corporation and has given proper notice, newer construction, and some owner-occupied duplexes.5California Legislative Information. California Civil Code 1946.2 Some cities layer their own rent stabilization and just cause rules on top of state law, and those can impose additional procedural steps.
Filing the Unlawful Detainer
If the tenant doesn’t move out within three days of proper service, the landlord files an unlawful detainer complaint in the Superior Court for the county where the property sits. Unlawful detainer is a specialized, expedited lawsuit built to resolve possession quickly.
After filing, the summons and complaint must be formally served on the tenant. The tenant then has 10 days, excluding Saturdays, Sundays, and judicial holidays, to file a written response.6Los Angeles County Department of Consumer and Business Affairs. Eviction If no response comes, the landlord can request a default judgment. If the tenant responds, trial is typically set within about 20 days.
Defenses the Tenant Can Raise
A nuisance filing is not an automatic win. Tenants can raise several defenses, and any of them, if supported by evidence, can delay or defeat the eviction:
- Defective notice. If the three-day notice lacked required information, was served improperly, or described the wrong facts, the case can be dismissed. This defense succeeds often, because the notice rules are strict and landlords regularly miss them.7Judicial Branch of California. Eviction Defenses
- Retaliation. If the tenant recently complained to an agency about habitability or exercised other legal rights, the landlord generally cannot evict within 180 days of that complaint.8California Legislative Information. California Civil Code 1942.5
- Discrimination. Fair housing laws prohibit evictions motivated by race, religion, disability, family status, sexual orientation, or other protected characteristics.7Judicial Branch of California. Eviction Defenses
- Domestic violence protections. A tenant who is a victim of domestic violence, sexual assault, stalking, or human trafficking cannot be evicted for incidents related to that abuse if they can document it with something like a police report or restraining order.7Judicial Branch of California. Eviction Defenses
- Habitability. If the landlord ignored serious maintenance problems, the tenant may argue the landlord’s own failures contributed to the conditions being labeled a nuisance.7Judicial Branch of California. Eviction Defenses
After the Court Rules
If the landlord wins, the court issues a judgment and the landlord obtains a Writ of Execution authorizing the sheriff to enforce it. The sheriff posts a Notice to Vacate giving the tenant five days to move out. If the tenant stays, the sheriff returns, removes the tenant, and changes the locks.9Judicial Branch of California. After the Eviction Trial Decision
The judgment can also award unpaid rent and damages, and the same Writ of Execution lets the landlord pursue collection if the tenant doesn’t pay voluntarily.9Judicial Branch of California. After the Eviction Trial Decision
What the Eviction Leaves Behind
A nuisance judgment follows the tenant for years. Screening companies pull eviction records from court databases, and many landlords reject applicants with any eviction on file regardless of the circumstances. Under federal law, eviction records can appear on screening reports for up to seven years, and court records themselves often stay publicly searchable longer than that.
Unpaid rent or damage awards sent to collections can show up on the tenant’s credit file for up to seven years and pull down a credit score. For a tenant facing a nuisance case with weak defenses, negotiating a voluntary move-out in exchange for dismissal before a judgment is entered is often worth exploring.
