Can a tenant change the locks in California?

Most leases require landlord permission and a copy of the new key. A tenant changing locks without permission and without providing a copy is typically a lease violation. The exception: Civil Code §1941.5 gives domestic violence victims the right to change locks at their own expense and provide the landlord a copy.

What is the procedural path?

3-day cure or quit citing the lock-change clause. Cure = provide the landlord a copy of the new key. If the tenant complies, case closed. If not, UD on the lease-violation just cause.

What about the §1941.5 domestic violence exception?

Under §1941.5, a tenant who is a DV victim with a protective order can change locks at their own expense and must provide the landlord a copy within 24 hours. The landlord cannot retaliate. Don't serve a cure-or-quit on a DV-protected lock change.

Does the landlord lose access rights?

No. The landlord still has §1954 access rights with 24-hour notice. The tenant must allow access. Failure to allow noticed entry is itself a separate lease violation.

Can the landlord change locks back?

No. That's wrongful self-help under §789.3 — triple damages, attorney's fees. The procedural path is cure or quit followed by UD if not cured.
