Who is responsible for AC mold and cleaning costs?« Back to Previous Page

Responsibility for AC mold and cleaning costs typically falls on the landlord if the issue stems from a building or AC system defect, but on the tenant if it's due to a lack of maintenance or occupant habits. In JVC, summer's high humidity and constant AC use create ideal conditions for condensation and mold in poorly ventilated spaces like closets against external walls.

Your first step is to formally notify the landlord or property management company in writing, with photos. They are generally responsible for the structural integrity of the building and the proper functioning of the AC system. If the mold is a result of a leaking pipe, inadequate insulation in the external wall, or a faulty AC drain line, the repair and remediation cost is theirs.

However, if the issue is determined to be from not running the AC sufficiently to control humidity or blocking ventilation grilles, the cost may be yours. For contaminated clothing, liability is less clear; it often depends on the lease agreement and the cause.

Given the visible growth, a professional inspection is advisable to identify the moisture source definitively. This provides an objective report to determine liability. For now, move affected items to a dry, well-ventilated area to prevent further spoilage.
