Maryland indoor moisture briefing Evidence note 41
Mold Planning for a Commercial Building
Larger buildings need one documented plan for moisture, occupants, operations, HVAC zones, contractors, and completion.
Short answer
Start with evidence you can name
A commercial project adds occupants, operating schedules, multiple HVAC zones, leases, records, safety programs, and business continuity to the building-material problem. EPA’s larger-building guidance emphasizes planning, communication, moisture correction, containment, and professional judgment.
Safety boundary: If there is contaminated water, structural damage, an electrical hazard, unsafe access, suspected HVAC contamination, or a health concern, stop and use the appropriate qualified help. For this topic, first note assessment, remediation, hvac, industrial hygiene, reconstruction, and management roles.
