The short answer

Start with Your HOA Documents

Your HOA's declaration, bylaws, and rules spell out who maintains what. Look for sections on maintenance, repair, and responsibility for common areas versus individual units. Often, the HOA covers exterior and structural elements, while you handle interior surfaces and fixtures.

If the mold stems from a leak in a shared pipe or a roof, the HOA may be responsible for fixing the source and the resulting damage. If the leak comes from a fixture inside your unit, like a sink or bathtub, you likely own the remediation. Read your documents carefully before you approach the board.

Identify the Moisture Source

Mold needs moisture to grow. The source of that moisture often decides responsibility. A leak from a common roof, a shared wall, or a main water line points to the HOA. A leak from your own plumbing, a window you failed to seal, or high humidity from your daily activities points to you.

Document the source as well as you can. Take photos, note the date you first saw the mold, and keep any maintenance records. If the source is unclear, a water damage inspection can help pinpoint where the moisture enters. The pros can use moisture mapping to trace the path.

  • Check your CC&Rs for a maintenance matrix
  • Photograph the mold and any visible water stains
  • Note the date and any prior leaks or repairs
  • Ask your HOA for their maintenance records
  • Look for signs of a roof, pipe, or window leak
  • Keep a log of all communication with the board

Talk to Your HOA Board

Once you have a clear picture, contact your HOA board in writing. Explain what you found, where it is, and what you believe caused it. Ask them to inspect the area and determine their responsibility. A written request creates a paper trail that helps if the dispute escalates.

The board may have their own inspectors or may ask you to get a water damage inspection. If the mold is in a common area, the HOA should handle remediation. If it's in your unit, you might need to coordinate with the board to ensure the source is fixed, especially if it's a shared wall or pipe.

Handle the Remediation Safely

Mold remediation is not a simple cleanup. Small patches on non-porous surfaces can be wiped with soap and water, but larger areas, especially on drywall or insulation, need professional removal. The pros can contain the area, remove contaminated materials, and dry the structure to prevent regrowth.

If you are responsible, consider hiring local water damage pros for structural drying and dehumidification after the mold is removed. They can also perform post-remediation clearance testing to confirm the mold is gone and the air is safe. Always wear protective gear and avoid disturbing mold spores.

Resolve the Dispute

If the HOA disagrees about responsibility, you have options. Review your state's laws on HOA obligations and common area maintenance. Some disputes go to mediation or arbitration as outlined in your governing documents. A qualified attorney can help you understand your rights.

Keep your own records and communicate in writing. If the HOA is responsible and delays, you may need to escalate. In the meantime, address any health concerns: see a doctor if you feel unwell. For the mold itself, you can hire a mold professional to assess the situation and provide a remediation plan.

  • Review your state's HOA laws
  • Consider mediation before legal action
  • Keep copies of all emails and letters
  • Ask a qualified attorney if you are unsure
  • Do not ignore the mold, it can spread
  • Protect your health with masks and gloves

Frequently asked questions

What if the mold is in a wall that I share with my neighbor?

Shared walls are often considered common property, so the HOA may be responsible. Check your CC&Rs and ask the board. If the leak originates from one unit's plumbing, that owner may be liable. Document the situation and seek a professional inspection.

Can I withhold my HOA dues to pay for mold cleanup?

Withholding dues is risky. Most HOAs have rules against it, and you could face penalties or liens. Instead, file a claim with your insurance if you have coverage, and pursue a dispute resolution process. Consult a qualified attorney before taking such a step.

Does my insurance cover mold damage in a condo or townhome?

Policies vary, and your insurer decides what is covered. Your HOA's master policy may cover common areas, while your own policy covers your unit's interior. Check both policies and ask your insurance company for a clear explanation. If the mold stems from a covered water loss, you may have limited coverage.
