Mold Charges and Your Oregon Security Deposit

Mold is typically a landlord's maintenance responsibility in Oregon, not the tenant's fault. Under Or. Rev. Stat. §90.300, landlords cannot charge tenants for conditions that result from the landlord's own failure to maintain the property in habitable condition. Landlords cannot charge for mold remediation when the mold stems from building defects, inadequate ventilation systems, roof leaks, or pre-existing conditions. Tenants may be responsible only in narrow circumstances: if they caused water intrusion (such as leaving windows open during rainstorms repeatedly), failed to report a known leak in a timely way, or created persistent excessive humidity conditions — but even then, the landlord must prove the connection. If mold existed at move-in, your landlord cannot retroactively charge you for it.

Tenant Tip

Landlords must maintain units free from health hazards including mold. If mold existed at move-in (document with photos), or if it resulted from building conditions outside your control, your landlord cannot charge you for its remediation. Report any mold in writing during your tenancy to create a record.
