Neighbor Harassment Laws in California: Restraining Orders

Neighbor harassment laws in California give you several routes, and the right one depends on what your neighbor is actually doing. The main tool is a civil harassment restraining order under Code of Civil Procedure Section 527.6, which can order a neighbor to stop contacting you and stay away from your home for up to five years.¹ Separately, you can bring a nuisance claim for ongoing disturbances, call police when conduct crosses into assault, threats, or stalking, and file a federal fair housing complaint if the harassment targets you because of race, religion, disability, or another protected characteristic.

What Counts as Harassment Under California Law

Not every difficult neighbor is a harassing one in the eyes of the court. California defines civil harassment as one of three things: unlawful violence, a credible threat of violence, or a knowing and deliberate course of conduct directed at a specific person that seriously alarms or distresses them and serves no legitimate purpose.¹ The conduct has to be severe enough that a reasonable person would suffer substantial emotional distress, and you must actually experience that distress.

Unlawful violence covers physical acts like assault or battery. A credible threat is a statement or gesture that would make a reasonable person genuinely fear for their own safety or their family’s, where the person appears able to carry it out. A course of conduct is a series of acts over any period of time showing a continuing purpose, such as following you, repeated unwanted contact, or harassing messages sent by any means.¹

One boundary matters here: constitutionally protected activity is explicitly excluded. If a neighbor puts up political signs you find offensive or speaks at council meetings about your property, that is protected speech and will not support a harassment claim. A one-time argument, a dog that sometimes barks, or music you dislike are frustrations, not statutory harassment. The law requires a pattern or a genuine threat.

Nuisance Claims for Ongoing Disturbances

Some neighbor problems cause real harm without targeting you personally. Persistent loud noise, foul odors, smoke, or anything that interferes with the comfortable use of your property may qualify as a nuisance under California Civil Code Section 3479, which defines a nuisance as anything injurious to health, offensive to the senses, or obstructing the free use of property.²

A nuisance case is a civil lawsuit seeking an injunction to stop the behavior, monetary damages, or both. This route fits better when the problem is a condition rather than personal targeting. Constant noise and fumes from a backyard operation that make your patio unusable are classic nuisance territory, even if the neighbor bears you no grudge.

Documenting the Harassment

Whatever route you pursue, evidence decides the outcome. Judges rule on what you can show, not on how upset you are. Start a written log now if you haven’t already.

For each incident, record the date, time, and location, and write a factual description of what happened, including any specific words used. Keep it clinical. “Neighbor stood on my driveway at 7:15 a.m. and shouted, ‘I’m going to make your life hell'” is useful. “Neighbor was being threatening again” is not.

Collect physical evidence when you can: photographs or video of property damage, screenshots of threatening texts or social media messages, and audio recordings where legally permissible. California requires all-party consent for audio, but video of your own property is generally fine. Keep a list of witnesses with contact information.

Before going to court, consider sending a written cease-and-desist letter telling the neighbor the behavior must stop. It isn’t required, but if the conduct continues after the letter arrives, that continuation helps show the behavior is knowing and deliberate, which is exactly what the statute requires. For situations that haven’t escalated to threats or violence, county-level dispute resolution programs offer mediation with a trained mediator, and the state’s Department of Consumer Affairs maintains a directory.³ Once threats or violence enter the picture, skip mediation and go to the restraining order process or the police.

Filing for a Civil Harassment Restraining Order

When documentation and informal steps haven’t worked, you can petition the superior court in the county where you or the neighbor lives. Three forms start the case:

Form CH-100, the petition itself, where you describe the harassment using your incident log.
Form CH-109, the notice of court hearing.
Form CLETS-001, confidential information provided to law enforcement so they can enforce the order.⁴

If your petition alleges that the neighbor inflicted or threatened violence, stalked you, or placed you in reasonable fear of violence, there is no filing fee, and the waiver also covers related subpoenas and the other party’s response.¹ Petitions that don’t involve violence or threats carry a standard filing fee, and a fee waiver based on income is available.

The Temporary Restraining Order

After you file, a judge reviews the petition and may issue a Temporary Restraining Order without notifying the neighbor. The court must grant or deny the TRO request the same day you file, or the next business day if you filed too late in the afternoon.¹ To get one, you need reasonable proof of harassment and a showing that you’ll suffer serious or irreparable harm without the order.

A TRO typically bars the neighbor from harassing you, requires them to stay a set distance from you, your home, and your workplace, and prohibits all contact. It lasts up to 21 days, or 25 if the court extends it for good cause, and stays in effect until the full hearing.¹

Serving the Neighbor

Your neighbor has to be formally served with the petition and the TRO before the hearing. You cannot deliver the papers yourself. Service must be done by someone at least 18 years old who is not involved in the case, typically a professional process server or the county sheriff.⁵ If your order is based on stalking, violence, or a credible threat of violence, the sheriff or marshal serves the papers for free. After delivery, the server signs Form CH-200 (Proof of Personal Service), which must be filed with the court before the hearing. Without it, the judge cannot proceed.

The Hearing

The hearing takes place within 21 days of the TRO, or 25 with a good-cause extension.¹ Both sides present evidence and testimony. Bring your log, physical evidence, and any witnesses. Stay factual with the judge.

The judge must find harassment by clear and convincing evidence, a higher bar than the usual civil “more likely than not” standard. Vague complaints about attitude will not clear it. Specific, dated incidents with supporting evidence will. If the judge finds enough evidence, they issue an Order After Hearing that can last up to five years; if the order has no expiration date on its face, it defaults to three years. As the order nears expiration, you can request a renewal for up to five more years, and you do not need to show any new harassment to renew. The renewal must be filed within three months before the order expires.¹

What Happens If the Neighbor Violates the Order

Intentionally violating a civil harassment restraining order is a misdemeanor punishable by up to one year in county jail, a fine of up to $1,000, or both.⁶ Penalties climb when violations involve injury or repeat conduct:

A violation causing physical injury carries fines up to $2,000 and a mandatory minimum of 30 days in jail (up to one year), though a judge can reduce the minimum after at least 48 hours served.⁶
A repeat violation with violence within seven years can be filed as a felony, with potential state prison time.⁶
A repeat violation causing injury within one year carries a mandatory six-month minimum (up to one year), a fine up to $2,000, or state prison.⁶

If a violation happens, call the police right away and tell them there is an active restraining order. Officers can verify it through a law enforcement database. Document the violation the same way you documented the original harassment, since your record will support any criminal charge.

When to Call the Police

A civil restraining order is designed to prevent future harm, but some neighbor conduct is already criminal. If a neighbor physically assaults you, makes a credible threat of violence, or damages your property, call 911. These are emergencies police handle independent of any civil case.

Stalking under Penal Code 646.9 is one of the more serious charges arising from neighbor conduct. Repeatedly following or harassing someone while making credible threats carries up to one year in county jail, a fine up to $1,000, or state prison. If the stalking happens while a restraining order is already in place, the charge becomes a felony punishable by two to four years in state prison.⁷

Whenever police get involved, ask for a copy of the report. It provides an official third-party record that becomes powerful evidence in your civil restraining order case. Criminal and civil tracks run in parallel. A criminal charge does not replace the civil order that keeps the neighbor away from you, and a civil order does not substitute for criminal prosecution of violent acts.

Federal Fair Housing Protections

When harassment is motivated by race, color, religion, sex, national origin, disability, or familial status, federal law adds another layer. The Fair Housing Act makes it unlawful to coerce, intimidate, threaten, or interfere with any person exercising their housing rights, and it reaches neighbor-on-neighbor conduct when the behavior targets a protected characteristic and is severe enough to interfere with the ability to live in the home.⁸

If your neighbor uses racial slurs, tie threats to your religion, or intimidates you to drive you out because of who you are, you can file a complaint with the U.S. Department of Housing and Urban Development, which investigates at no cost. This federal claim runs alongside your state remedies, so a California restraining order and a HUD complaint can move forward at the same time.
