Q: Can I ask my NJ tenant to remove her security system?

A: It’s understandable that you want to regain control over your property, especially after the recent incident during the emergency repair. In New Jersey, tenants are allowed to use portable or personal security devices for their own safety as long as they do not damage the property or interfere with the landlord’s lawful access. However, since you originally gave verbal permission rather than written approval, that permission can be revoked if the system creates problems—such as triggering alarms during maintenance or blocking your legal right to enter the property in emergencies. You are entitled to require reasonable access to your property under state law, and the tenant’s security system cannot prevent that.

To address this, you should provide written notice to your tenant explaining your request that she remove or disable the security system. Be clear that your concern is not with her right to feel safe but with the interference it caused during your emergency entry. If you prefer, you can offer a compromise by allowing her to keep the system as long as it remains disarmed during repairs or inspections. Putting the communication in writing helps protect both of you and shows that you are acting reasonably and within your rights as a landlord.

If the tenant refuses and the system continues to interfere with your access, you can issue a written notice citing a lease violation for obstruction of entry or safety concerns. Make sure any request you make is consistent with your lease and state landlord-tenant laws to avoid disputes. While you cannot enter the home without proper notice except in emergencies, you can require that the property remain accessible when entry is necessary. Taking a calm, documented approach will help resolve the situation while protecting your rights as the property owner.
