“Nuisance” is one of the landlord’s favorite eviction tools because it sounds vague enough to fit anything, noise, smell, guests, parties, lifestyle, neighbor disputes. It is also one of the most successfully defended allegations because California law requires SPECIFIC conduct that substantially interferes with other residents’ rights, and the landlord has to prove it with admissible evidence.
For LARSO and AB 1482 covered units, nuisance is a “for-cause” termination ground (LAMC § 151.09(A)(4); CC § 1946.2(b)(1)(C)). For non-covered units, it can support an unlawful detainer under CCP § 1161(4). In every case, the standard is the same: substantial interference, supported by specific evidence, not general complaints.
We only represent tenants. Nuisance cases are highly defensible, most landlord witnesses don’t hold up at trial and most documentation is conclusory.
Quick Answer
Nuisance as an eviction ground requires specific conduct by the tenant that substantially interferes with the comfortable enjoyment of life or property of others (CC § 3479, CCP § 1161(4); LARSO § 151.09(A)(4); AB 1482 CC § 1946.2(b)(1)(C)). Vague complaints, single incidents, lifestyle differences, or generalized “annoyance” do not qualify. The notice must specify the conduct, the case must be proven with admissible evidence (often other tenant testimony).
Key Takeaways
- Civil Code § 3479, nuisance is conduct that interferes substantially with the use and enjoyment of property.
- CCP § 1161(4) — incurable conduct (nuisance) supports a 3-Day Notice to Quit.
- LARSO § 151.09(A)(4) — nuisance is a just cause, cure opportunity may be required for less serious conduct.
- AB 1482 CC § 1946.2(b)(1)(C) — at-fault just cause.
- The notice MUST specify the conduct, vague “you are creating a nuisance” is defective.
- Substantial interference required, minor annoyances, isolated incidents, or lifestyle differences don’t qualify.
- Defense witnesses (other tenants, neighbors who don’t see the issue) carry weight.
- Disability accommodation may apply if the alleged nuisance is related to a disability.
What “nuisance” actually means under California law
CC § 3479 defines nuisance broadly:
“Anything which is injurious to health, including, but not limited to, the illegal sale of controlled substances, or is indecent or offensive to the senses, or an obstruction to the free use of property, so as to interfere with the comfortable enjoyment of life or property, or unlawfully obstructs the free passage or use, in the customary manner, of any navigable lake, or river, bay, stream, canal, or basin, or any public park, square, street, or highway, is a nuisance.”
Key words: “substantially” interferes, affects the “comfortable enjoyment of life or property.” Trivial annoyances don’t qualify. Single incidents usually don’t qualify. The conduct must be ongoing, substantial, and provably connected to the tenant.
What landlords typically allege
- Loud noise (music, parties, yelling, fighting).
- Strong odors (cooking, smoking, marijuana, pets).
- Excessive guests / “rotation” of occupants.
- Verbal altercations with neighbors.
- Hoarding.
- Pets that bark or defecate inappropriately.
- Disturbances at unusual hours.
- Threats to other tenants.
- Drug or alcohol use perceived to affect others.
Why nuisance cases are often winnable
Defective notice
“You are creating a nuisance” is not specific enough. The notice has to describe the conduct: dates, times, what specifically happened. Vague allegations fail under Foster v. Williams (2014) 229 Cal.App.4th Supp. 9.
Single-incident vs. pattern
Isolated incidents rarely qualify. A pattern of multiple, substantial incidents over time is required for the “substantial interference” standard.
Source of disturbance
Landlord must prove the tenant is the source. Noise from a neighboring building, traffic, construction, or other tenants is not the tenant’s nuisance. Witness testimony from neighbors who can’t identify the source, or who identify a different source, defeats the case.
Counter-witnesses
Other tenants who don’t experience the issue (or who can confirm a different source) are powerful defense witnesses. Building manager complaints from one or two specific other tenants are often outweighed by neutral testimony.
Disability accommodation
If the alleged nuisance is related to a disability (e.g., loud TV because of hearing impairment, frequent visitors for caregiving), a reasonable accommodation may be required before termination, and the failure to engage in the interactive process is a defense.
Retaliation
Nuisance allegations frequently emerge after a tenant complains about habitability. Timing matters. CC § 1942.5 presumption may apply.
Cure opportunity
For LARSO covered units, some nuisance grounds require a notice with opportunity to cure before termination. Skipping the cure step is fatal.
What the landlord has to prove
- Specific conduct by the named tenant.
- The conduct was substantial, not trivial.
- The conduct interfered with the use and enjoyment of others.
- If a cure opportunity was required, the landlord gave one.
- If covered by LARSO/AB 1482, the just-cause statement was properly given.
What to do right now
- Save the notice and read it carefully, is the conduct described specifically?
- Document what the conduct actually is, your version of events with dates and times.
- Identify witnesses (other tenants, neighbors, guests) who can confirm or deny.
- If a recurring source of noise exists (neighbors, construction, traffic), document that too.
- If a disability is involved, request a reasonable accommodation in writing.
- Check the retaliation timeline, did the notice come after a complaint or repair request?
