What Can I Do If I’m Having a Problem With an Aggressive Neighbor? 

Living in close proximity to others means occasional disagreements are inevitable, but what happens when a neighbor’s behavior becomes threatening or aggressive? Whether it’s verbal harassment, property damage, or physical intimidation, dealing with an aggressive neighbor can feel unsettling. Fortunately, California law and local resources offer ways to address these issues while keeping your rights intact. 

Recognizing the Problem 

Consider Miguel’s story: He moved into a new apartment, excited about his quiet neighborhood. At first, his interactions with his downstairs neighbor seemed normal, but things quickly changed. The neighbor started yelling at him for walking too loudly, banging on the ceiling late at night, and once even blocked Miguel’s car in the parking lot, demanding he “learn how to live respectfully.” Miguel felt threatened and unsure of what to do. 

Aggressive behavior like Miguel’s neighbor’s actions can escalate quickly, making it essential to address the problem early. Aggression may include verbal threats, physical intimidation, destruction of property, or even repeated harassment through noise or other disturbances. 

Steps You Can Take 

If you’re dealing with an aggressive neighbor, the first step is to remain calm. Direct confrontation might feel tempting but could escalate the situation. Instead, try these strategies: 

Document the Incidents: Write down details about each encounter, including dates, times, and what occurred. If possible, gather evidence, such as photos or video recordings. 

Speak to Your Landlord, in Writing: If the neighbor is another tenant, notify your landlord. California landlords are responsible for addressing disruptive behavior that interferes with your “quiet enjoyment” of the property under California Civil Code § 1927 and, potentially, under local city/county law as well.  

Contact Local Authorities: If the behavior becomes dangerous, don’t hesitate to involve the police. Harassment, threats, or property damage may violate California laws, including California Penal Code § 422, which covers criminal threats. 

Finding a Resolution 

In Miguel’s case, he documented his neighbor’s actions and reported them to his landlord, who issued a formal warning to the neighbor. When the behavior persisted, Miguel contacted local authorities, who investigated and encouraged the landlord to take further action. While the situation took time to resolve, Miguel was able to feel safe in his home again. 

If your landlord or local authorities fail to act, consulting a tenant rights attorney can help you explore legal remedies, such as restraining orders or compensation for damages caused by the neighbor’s actions.
