California Landlord Duties After a Wildfire or Disaster (SB 610)

After the 2025 Los Angeles fires, many tenants were told that smoke and ash cleanup was their problem. SB 610, effective January 1, 2026, settles that question: it's the landlord's. The law also pauses rent during mandatory evacuations. It has already been triggered at least once, by the May 2026 Garden Grove chemical emergency evacuation in Orange County.

Duty 1: Clean Up Disaster Damage (Civil Code §1941.8)

When a disaster damages a rental, the landlord must, within a reasonable time:

• Remove debris caused by the disaster, and
• Mitigate hazards caused by the disaster, including mold, smoke, smoke residue, smoke odor, ash, asbestos, and water damage

"Reasonable time" isn't defined. It depends on the severity of the damage, access restrictions, and contractor availability. Document every delay.

If authorities issue cleanup protocols (such as requiring licensed remediation contractors), follow them.

The Toxic Debris Presumption

This is the biggest shift. Until a local public health agency determines that disaster debris (ash, sludge, runoff) isn't toxic, its presence at the unit is presumed to make the unit uninhabitable. Previously, debris alone didn't automatically mean that. Now the burden is effectively on you to show the unit is safe.

Notify the Tenant When You're Done

Once remediation is complete, if the tenant gave you a mailing or email address, you must notify them in writing that the work is done, and that they can view (and, on request, get copies of) any environmental studies, testing, or reports.

Same Rent When They Return

Tenants who return after the disaster are entitled to the same rent that was in effect before it.

You are not required to rebuild a property that was destroyed, and you keep your existing rights to end tenancies as the law allows. Local ordinances can add more protections.

Duty 2: No Rent During Mandatory Evacuations (Civil Code §1941.9)

During a government-mandated evacuation order tied to a qualifying disaster, the tenant's obligation to pay rent is suspended for the evacuation period.

• Prepaid rent covering the evacuation days must be refunded within 10 calendar days after the order is lifted, or credited against the next month's rent
• If the tenancy ends because the unit was destroyed, or the tenant terminates because of substantial damage, refund prepaid rent covering the period after termination within 21 calendar days
• This applies only to mandatory evacuation orders, not voluntary departures

SB 610 doesn't add new penalties, but tenants can enforce it through existing remedies: rent abatement claims, eviction defenses, and lawsuits for damages.

A Disaster Checklist for Landlords

• Note the exact start and end dates of any evacuation order covering your property
• Prorate rent for those days and refund or credit within 10 days of the order lifting
• Photograph damage before cleanup and keep every contractor invoice and test result
• Don't let tenants back into a unit with untested debris present
• Send the written completion notice and keep a copy
• Call your insurer early about loss-of-rent coverage

Bottom Line for Landlords

1. After a disaster, you must remove debris and mitigate hazards like smoke, ash, mold, and water damage within a reasonable time
2. Debris is presumed toxic, and the unit presumed uninhabitable, until local public health says otherwise
3. Send written notice when remediation is complete and share any test reports on request
4. Returning tenants keep their pre-disaster rent
5. Rent is suspended during mandatory evacuations, so refund or credit prepaid rent within 10 days after the order lifts
