Failure to remove contaminated materials and to reduce moisture and humidity after a flood can present serious long-term health risks. Standing water and wet materials are a breeding ground for microorganisms, such as viruses, bacteria and mold. They can cause disease, trigger allergic reactions and continue to damage materials long after the flood.

Property Manager & Landlord Requirements

Landlords are required to fulfill certain legal requirements (Warranty of Habitability, CRS 38-12-503) that make a rental property fit for human habitation. Buildings that have been flooded must be thoroughly dried and evaluations must be conducted during and after remediation. Property managers should conduct a visual inspection and document remediation efforts to ensure properties have been properly remediated to prevent mold health problems.

Documentation of Mold Remediation Efforts

Environmental Sampling

Environmental sampling for mold can help to determine the extent of the problem, the location of mold, and the quality of the remediation. However, sampling for mold cannot be used to determine if a building is “safe” because there are no quantitative, health-based guidelines that describe “safe” levels for microbial exposure to mold. Instead, property owners and managers should conduct a visual inspection and document remediation efforts to ensure appropriate steps have been taken to prevent mold health problems.
