A recurring leak, damp wall, or patch of suspected mold can leave a tenant uncertain about what to report and a property owner uncertain about the response required. In Washington, D.C., written notice matters. So do the inspection date, the work performed, and whether the underlying moisture problem has been addressed.

The District also changed its complaint process in 2026. Tenants and property owners should use current agency guidance rather than assume that older online instructions still apply.

Send a clear written notice

D.C. Code § 8-241.04 addresses notice of indoor mold or suspected indoor mold in a tenant’s dwelling unit or a common area. A tenant does not need to describe the condition with scientific certainty to report a concern under this provision.

Send the property owner a dated email, text message, or letter. Identify the location, describe what you observed, and explain when you first noticed it. Mention associated leaks or recurring moisture. Attach photographs if you can take them safely, and retain the original message and attachments. Follow any applicable lease notice instructions as well.

Keep the description factual. “Dark spots appeared on the bedroom wall after the ceiling leak” is more useful than guessing the type of mold or making an unsupported claim about its cause. Ask how the owner plans to arrange an inspection and communicate about repairs.

Understand the inspection and remediation deadlines

Under D.C. Code § 8-241.04, a residential property owner who receives written or electronic notice from a tenant must inspect within seven days. The statute calls for remediation within 30 days of the inspection, unless a court or the Mayor orders a shorter timeframe.

Those are separate periods. The 30-day period runs from the inspection under the statutory text; it is not described as 30 days from the tenant’s first notice. The inspection obligation itself remains time-sensitive.

Property owners should record when notice arrived, arrange access, document the inspection, and identify the work needed. Tenants should retain messages about offered inspection dates and access arrangements. A clear record helps explain what occurred if the parties later disagree.

Arrange appropriate assessment and remediation

Mold assessment and remediation are distinct activities, and DOEE licenses professionals in both areas. Ask any proposed provider what license the individual holds, whether it is current, and whether it covers the work being proposed. DOEE’s mold professional licensing information is a useful starting point.

Current DOEE tenant guidance states that when indoor mold growth covers 10 square feet or more, assessment and remediation must be performed or supervised by a DOEE-licensed mold professional. For smaller areas, applicable rules and guidelines may permit remediation by a non-licensed person, but the property owner still must address the reported condition and its moisture source. When the extent or required response is uncertain, consult DOEE or a licensed mold professional.

Where professional remediation is not required, § 8-241.04 still requires the owner to clean and remove indoor mold in accordance with the applicable agency guidelines. A small visible patch should not be treated as a reason to ignore a reported condition.

Ask how the moisture source will be addressed and how completion will be documented. Avoid disturbing suspected mold or opening walls simply to gather evidence. Whether an area can be safely assessed, occupied, or worked on calls for appropriate professional judgment. Questions about symptoms or medical care should be directed to a healthcare professional.

Use the current housing complaint route

According to DOEE’s June 12, 2026 memorandum, DOEE stopped conducting residential mold complaint inspections and deactivated its mold complaint link. The Department of Buildings now handles housing-code enforcement, including mold violations. DOEE continues licensing and regulating mold professionals.

For a housing inspection, use DOB’s current inspection page and select the housing-inspection option. Keep the request confirmation, inspection report, and any notices you receive. An agency report can be an important part of the record, but it should not be treated as a substitute for advice about court proceedings or other deadlines.

DOEE’s tenant guidance also identifies the Office of the Tenant Advocate and the Superior Court’s Housing Conditions Court as possible resources. The appropriate next step depends on the condition, the response, and the relief being sought.

Keep a record of the problem and the response

Save the lease, notices, photographs, inspection results, work orders, contractor communications, and receipts. Record dates when the condition changes or returns. If emergency work is needed, safety comes first; document the condition when it is safe and practical to do so.

If a professional assessment is obtained, retain the full report and proof of when it was sent to the owner. D.C. Code § 8-241.05 gives qualifying professional mold assessments a specific role in certain tenant claims or defenses, subject to the statute’s notice requirements. A report does not automatically establish every element of a claim or guarantee compensation.
