How Does an HOA Handle Mold in Common Areas?

Last updated October 26, 2026

The short answer

Who Is Responsible

In most planned communities, the HOA owns and maintains common areas such as hallways, lobbies, stairwells, and shared utility rooms. Mold in those spaces is generally the HOA's responsibility, not yours. The board must address the moisture source and the damage it causes.

Your own unit, including interior walls and personal belongings, falls under your responsibility. If mold starts in a common area and spreads into your unit, the HOA may need to fix the source, but you handle the cleanup inside your walls. Check your governing documents for the exact boundary.

What the HOA Usually Does

When mold appears in a common area, the board typically starts with a professional inspection to find the moisture source. That could be a leaking pipe, poor ventilation, or groundwater seepage. Once the source is fixed, the HOA arranges for water damage pros to dry the area and remove moldy materials.

The process often involves removing wet drywall or carpet, cleaning surfaces with appropriate antimicrobial treatments, and then rebuilding the space. The HOA may also improve ventilation or drainage to prevent a repeat. You may see notices about the work, but you usually do not need to leave your unit.

What You Should Do

If you spot mold in a common area, report it to the HOA board in writing. Include the location and a photo if you can. Keep a copy of your report. The board should respond with a plan and a timeline, but you can follow up if you hear nothing.

Do not try to clean large areas of mold yourself, especially if the mold covers more than a few square feet or is near HVAC systems. Breathing mold spores can irritate your lungs. See a doctor if you feel unwell after exposure.

When You Need Your Own Help

If the mold in your unit is separate from the common area issue, you may need to hire the pros on your own. They can inspect the extent, dry the space, and remove affected materials. This is especially true if the mold came from a leak inside your walls or under your sink.

The cost of your unit's cleanup depends on the size of the affected area, the materials involved, and the extent of the damage. In many cases, your homeowners insurance may help, but policies vary, and your insurer decides what is covered. Check your policy and talk to your agent.

Preventing Mold in Shared Spaces

You can help prevent mold in common areas by keeping shared spaces dry. Wipe up spills in laundry rooms or gyms, and report leaks or damp smells to the board quickly. Good ventilation is key, so do not block vents in common hallways or storage areas.

In a mild coastal climate with wet winters and dry summers, moisture can build up slowly. Regular checks of pipes and roof areas can catch problems early. If you live in a rainy region, keep an eye on shared entryways and basements during the wet season.

Frequently asked questions

Can the HOA charge me for mold cleanup in common areas?

Usually not for the common area itself, but if the mold came from your unit, such as a leaky pipe, the HOA may charge you for repairs to shared spaces. Check your governing documents and your insurance policy.

How long does the HOA have to fix mold in common areas?

There is no set legal deadline, but the board should act reasonably quickly to prevent further damage. If the mold spreads or causes health issues, you can document the delay and contact your local health department for guidance.

What if the HOA ignores my mold report?

Send a follow-up written notice and keep records of all communication. If the mold worsens and affects your health or property, you may need to consult a local housing authority or an attorney. Your insurance company may also offer advice.
