Why Does Mold Remediation Become an HOA Responsibility?

The HOA's responsibility for repairs, including mold cleanup, is determined by the property lines in your governing documents. Common areas, like clubhouses and exterior building walls, are owned and maintained collectively. Limited common elements, such as a balcony or a roof over your unit, are designated for one homeowner's use but are often an HOA maintenance duty.

If a plumbing leak starts in a pipe inside your wall, that is typically your responsibility. However, if that pipe serves multiple units or is part of the main building stack, it may be a common element. The exact division is specified in your HOA's Declaration of Covenants, Conditions, and Restrictions (CC&Rs).

Your HOA's CC&Rs and bylaws act as the rulebook for maintenance duties. These documents contain detailed exhibits, often called "maintenance charts," that list every building component. They explicitly state whether the HOA or the individual owner is responsible for its repair, replacement, and insurance. This chart is the primary document for resolving disputes over mold remediation costs.

If the documents state the HOA maintains "all exterior surfaces," then mold inside a wall cavity caused by failed exterior sealant is their duty. Conversely, if you are responsible for "everything within the interior surfaces of the walls," then interior pipe leaks fall to you. Always review these documents carefully when a water issue arises.

Once responsibility is established, the responsible party files an insurance claim. If the HOA is liable, they file a claim under the HOA's master policy for the common property damage. If you are responsible, you file with your own homeowner's (HO-6) policy. Policies vary, and your insurer decides what is covered. Mold coverage often has specific limits.

Professional mold remediation is not a DIY task. It requires containment, safe removal of affected materials, and structural drying to prevent recurrence. The process often concludes with post-remediation clearance testing by an independent mold assessor to verify the air is safe. This final step provides documentation that the job was completed properly.
