How Do HOA Communities Handle Mold in Common Areas?

Last updated October 25, 2026

The short answer

The HOA's Duty to Maintain Common Property

Your homeowners association is legally obligated to maintain common areas like lobbies, hallways, gyms, and laundry rooms. This duty includes addressing health and safety hazards such as mold growth. When mold is found, the HOA board or its property manager must take action to investigate and remediate the problem. They cannot ignore it, as it affects all residents who use the shared space.

The specific steps are usually outlined in the HOA's governing documents, like the Covenants, Conditions, and Restrictions. These documents define what constitutes a common area and set procedures for repairs. The board typically has the authority to hire necessary professionals and approve expenses for this work. Funding comes from the regular HOA fees paid by all homeowners.

Identifying the Source of Moisture

Mold cannot grow without a water source. The first critical step is finding and stopping that moisture. In common areas, leaks often come from plumbing inside walls, roof failures, faulty window seals, or condensation from HVAC systems. A persistent drip from a pipe or a past flood that was not properly dried are common culprits behind hidden mold.

Until the water problem is fixed, any mold cleanup will be temporary. The HOA should engage professionals who specialize in leak detection and moisture mapping. The experts use tools to find hidden moisture behind walls or under floors. Correcting the leak or intrusion is essential before any mold removal can permanently succeed.

  • Roof leaks around vents or flashing.
  • Condensation from air conditioning drip pans or ducts.
  • Leaking pipes for sprinklers, pools, or interior plumbing.
  • Failed seals around windows or sliding doors.
  • Past water damage from appliance overflows or fire sprinklers.
  • Poor ventilation in bathrooms, laundry rooms, or enclosed mechanical rooms.

The Professional Assessment and Remediation Process

For health and liability reasons, HOAs should hire the professionals. The experts determine the mold type and the extent of contamination. They provide a detailed protocol for safe removal, which the HOA can then use to hire a remediation contractor. Often, a separate firm performs the assessment to avoid any potential conflict of interest.

Remediation involves containing the area to prevent spore spread, removing moldy porous materials, and thoroughly cleaning all surfaces. The pros are often needed to dry the structure completely after the leak is fixed. Their work includes structural drying, dehumidification, and repairing the damaged building materials to restore the common area.

Costs, Insurance, and Special Assessments

The cost for mold remediation in common areas is paid from the HOA's operating budget or reserve fund. Expenses can vary widely depending on the mold's extent and the repairs needed. If the cause is a sudden, covered event like a burst pipe, the HOA's master insurance policy may contribute to the cost. Policies vary, and your insurer decides what is covered.

If the repair cost exceeds available funds, the HOA board may levy a special assessment on all homeowners. This is a one-time fee to cover the unexpected expense. The authority to do this is in the HOA's governing documents. Homeowners should review their HOA's financial health and reserve studies to understand how prepared the community is for such repairs.

What Homeowners Can Do and Expect

If you discover suspected mold in a common area, report it in writing to the HOA board or property manager immediately. Keep a copy for your records. You can ask about the planned response and timeline. While you cannot hire your own contractor for common areas, you have a right to expect the HOA to address the issue in a reasonable timeframe.

During remediation, access to the affected common area will likely be restricted for safety. The HOA should communicate these closures and any alternative arrangements. If you or your family members have health concerns related to mold exposure, consult a doctor. For disputes over the HOA's response, review your governing documents and consider mediation as outlined in their rules.

  • Document the mold with photos and a written notice to the board.
  • Understand that the HOA, not individual owners, manages the contractor.
  • Expect communication about project timelines and area closures.
  • Know that special assessments are possible for large, unfunded repairs.
  • Consult a doctor for any respiratory symptoms or health worries.
  • Refer to your CC&Rs for the formal dispute resolution process.

Frequently asked questions

Who pays for mold removal in a condo's hallway?

The HOA's master policy and reserve funds typically pay for mold remediation in common hallways. As a condo owner, you fund this through your monthly HOA dues. If the cause originated from within your unit, you might be responsible for fixing the leak source.

Can I clean the mold in the common laundry room myself?

It is not advisable. The HOA is responsible for maintenance and liability in common areas. DIY cleaning might not address the root moisture problem and could spread spores. The board should hire professionals to ensure safe, complete removal and proper drying.

What if the HOA ignores my report about mold?

Send a formal, written follow-up and keep records. If the board fails to act, it may be breaching its fiduciary duty. Review your HOA's governing documents for the official complaint process. In serious cases, homeowners may need to seek legal advice from a qualified attorney.
