How do I handle a noisy tenant?

Document the complaints. Issue a written warning citing the nuisance/quiet enjoyment lease clause. If the conduct continues, 3-day cure or quit. Sustained severe nuisance can rise to incurable, supporting a 3-day unconditional quit.

What documentation do I need?

Written third-party complaints (other tenants, neighbors), police reports if any, dates and times of incidents, your own contemporaneous observations. The case at UD trial turns on whether the pattern was severe and ongoing.

When does noise rise to incurable?

Ongoing severe disruption after warnings, escalating conduct, threats to other tenants, conduct so disruptive that other tenants begin leaving. The line is severity plus continuing pattern. One loud party is curable; weekly disturbance over months may be incurable.

Can other tenants force me to act?

Other tenants have a right to quiet enjoyment. If a landlord knows about ongoing disruption and doesn't act, complaining tenants can pursue rent abatement or constructive eviction claims. The landlord's duty isn't only to the noisy tenant — it's to the building.

What about loud arguments or domestic conflict?

Walk carefully. Domestic violence protections (Civil Code §1946.7, §1941.5) can limit landlord action where the noise stems from DV. The tenant who is the victim can't be evicted for the violence; the perpetrator can. Document carefully and consult counsel.

Nuisance · Quiet enjoyment

Tenant is the building's noise problem. Document, warn, escalate.

Three steps: written third-party complaints + landlord warning + cure or quit. Severe sustained patterns can rise to incurable. Other tenants have rent-abatement rights if the landlord doesn't act.

TL;DR

Document third-party complaints, police reports, dates/times. Written warning citing nuisance/quiet enjoyment clause. Cure or quit if continues. Severe ongoing pattern can rise to incurable nuisance (3-day unconditional quit). Watch DV context — different rules apply.
