Lock Changing Rules for New Hampshire Tenants

Feeling secure in your rental is essential, especially if you're worried about lock changes or emergency protections. As a renter in New Hampshire, understanding your rights about locks, notification requirements, and landlord obligations helps you take control of your personal safety—without risking your tenancy or violating the law.

When Can Tenants Change Locks in New Hampshire?

In New Hampshire, the law does not directly prohibit tenants from changing locks, but it outlines specific expectations and rights for both renters and landlords. The key is to maintain open communication and abide by your lease agreement and state regulations.

Your Right to Privacy and Security

Under NH RSA 540-A:3, tenants have a right to privacy in their rental home. Landlords may only enter the property for specific reasons (like repairs or emergencies) and must usually provide advance notice. As a tenant, you also have the right to feel secure in your unit, but that does not always mean you can change locks unilaterally.

Common Scenarios for Lock Changes

  • After a break-in or domestic violence incident: You may want to change the locks for personal safety. Always inform your landlord or property manager immediately.
  • Ongoing harassment or threats: In these cases, contacting law enforcement and notifying your landlord is crucial.
  • Routine maintenance or lost keys: Some landlords may agree to a lock change but may require you to provide them a new key.

Always review your lease, as many include clauses regarding permission for changing locks. Without explicit permission, changing locks without landlord consent could violate your rental agreement.

Does the Landlord Have to Approve?

While New Hampshire law does not specifically address lock changes by tenants, general legal guidance and standard lease agreements require:

  • Written permission from your landlord before making any alterations, including lock changes
  • Promptly providing a copy of the new key to the landlord for emergency access

Without landlord consent, changing locks could be considered a violation of your lease, potentially resulting in eviction proceedings. To avoid issues, always get written approval and keep a record of your communications.

Protective Orders and Emergency Situations

Victims of domestic violence may have special rights regarding lock changes. If you have an active protective order, you can request lock changes as part of your court order.

If you need a lock change due to domestic violence, speak to your local District Court about including it in your protective order. Share any court documentation with your landlord.

For information, see the New Hampshire Circuit Court, District Division.

No standard statewide form exists for tenant-requested lock changes unrelated to protective orders. Always get landlord consent in writing for your records.

How to Address Lock Change Requests

  • Review your lease for terms about security hardware changes
  • Explain your reason to your landlord in writing (email or letter)
  • If permitted, coordinate a professional lock change, provide the landlord with a new key, and keep receipts
  • If denied and you feel unsafe, seek advice from local resources or court assistance, especially in emergency scenarios

Summary: Most lock changes in New Hampshire require landlord approval, except when ordered by a court. Open communication and documentation protect you from future disputes.
