A government office building in downtown West Palm Beach, Florida, has been dealing with persistent mold growth for over a year—and the situation is raising important questions for homeowners across the Sunshine State about the hidden risks lurking in their own walls.
The building on Third Street, which houses the Palm Beach County State Attorney's and Public Defender's offices, has shown signs of mold contamination since summer 2025. Employees have documented water stains, visible spores, and black mold growing around stairways and elevators. One worker took matters into their own hands and had samples tested, which revealed multiple potentially toxic forms of mold. At least one employee has received a doctor's note recommending they be relocated due to health concerns.
Palm Beach County officials have scheduled a third-party mold assessment for September 21, 2026. They attribute the ongoing problem to the building's original 1990 design combined with Florida's intense heat and humidity in recent months.

Florida's subtropical climate creates ideal conditions for mold growth. High humidity, frequent rain, and warm temperatures year-round mean that moisture can accumulate in walls, ceilings, and other hidden areas. When buildings—whether commercial or residential—have design flaws or aging infrastructure, the problem gets worse.
The Palm Beach County building situation shows how quickly mold can take hold when water intrusion goes unchecked. The 1990 construction date means the building is over 35 years old, and older structures often have ventilation systems and materials that struggle to keep up with Florida's demanding climate.
According to MycoTest's state-by-state environmental hazard map, Florida shows elevated risk for humidity-driven mold, hurricane water damage, and issues related to aging housing stock. Homeowners in the state face these same challenges that are affecting the West Palm Beach office building.
Warning Signs Every Homeowner Should Know
The employees at the Palm Beach County building noticed several telltale signs that homeowners should watch for in their own properties:
- Water stains on ceilings, walls, or around windows
- Visible spores or dark patches in corners, near pipes, or around HVAC vents
- Musty odors that persist even after cleaning
- Peeling paint or bubbling wallpaper that suggests moisture behind surfaces
- Health symptoms that improve when you leave the building
Mold often grows in places you cannot easily see—inside walls, under flooring, or in attic spaces. By the time it becomes visible around stairways or elevators like in the West Palm Beach case, the infestation may already be widespread.
What Florida Homeowners Can Do Now
Unlike a large government building that requires third-party assessments and bureaucratic scheduling, homeowners can take action immediately. The key is not to wait until mold becomes visible or until someone in your household starts experiencing symptoms.
Proactive testing is especially important in Florida, where the combination of humidity, older homes, and frequent storms creates ongoing risk. If your home was built before 2000, has ever experienced water damage from a leak or flood, or if you notice any of the warning signs listed above, testing should be a priority.
Surface sampling can detect mold spores that have settled on materials in your home. This type of testing identifies what types of mold are present so you can make informed decisions about remediation if needed.
Frequently Asked Questions
How do I know if my Florida home has hidden mold?
Look for water stains, musty smells, peeling paint, or condensation on windows. Because Florida's humidity can cause mold to grow inside walls and other hidden areas, surface testing can help detect spores even when you cannot see visible growth.
Can mold from water damage spread through a building?
Yes. Once mold establishes itself in one area, spores can travel through air ducts and settle on surfaces throughout the building. This is why the Palm Beach County situation showed mold around both stairways and elevators—areas connected to the building's ventilation.
Should I test for mold after a Florida hurricane or heavy rain?
Absolutely. Any water intrusion—from a hurricane, tropical storm, roof leak, or plumbing issue—can create conditions for mold growth within 24 to 48 hours. Testing after water damage gives you peace of mind and helps you catch problems early.
The situation in West Palm Beach serves as a reminder that mold does not discriminate between government buildings and private homes. Florida homeowners should take the warning seriously. With the state's year-round humidity and aging housing stock, the risk is real—and so is the solution. The MycoTest DIY Mold Test Kit lets you collect surface samples at home and send them to an accredited lab for certified results, all for $45 with no need to schedule an inspector.
