Mold Monitoring Programs for Commercial Building Owners

Environmental concerns over the last couple of decades have come to play a major role in commercial real estate development and management. Over the last five to ten years greater emphasis has been placed upon mold and indoor air quality (IAQ) than perhaps any other environmental issue. Among IAQ issues, concern about toxic mold has risen to present such a liability and perception concern that forward-thinking real estate property managers routinely have their buildings inspected as part of a Proactive IAQ Monitoring Program. In California, California’s Toxic Mold Prevention Act multiplies building owners’ concerns about this issue, since it formally establishes mold as a substandard condition that should be disclosed during a real estate transaction.

Advantages of a Proactive Program to Property Owners

  • The program professionally documents a record of indoor environmental monitoring in the building. This builds true value into the property that will be realized when the time comes for the property to be sold.
  • California’s “Toxic Mold Protection Act” requires commercial, industrial and residential building owners to disclose the presence of mold during real estate transactions. Proactive IAQ/mold monitoring helps protect owners against this liability. It demonstrates that the owner has done due diligence to assure a healthy building or portfolio of buildings.
  • The program reduces the chances of a “healthy” building from becoming “sick.” Problems or potential problems are quickly identified and corrected at minimal expense.
  • The proactive IAQ/mold report provides critical third party documentation certifying effective maintenance standards and supporting engineering or operation budgets.

    The program enhances the relationship of management and tenants by demonstrating a genuine concern for the tenant’s employees. Less time is devoted to investigating and solving tenant complaints.

    The “Toxic Mold Protection Act” in California

    The Toxic Mold Protection Act (SB 732), was signed in to law by Gray Davis in late 2001. It includes requirements for the California State Department of Health Services to develop standards for levels of bacteria and fungi either in HVAC systems or buildings in general. This is likely to be a very difficult task technically. The bill also requires the Department to provide public education, and for commercial, industrial and residential building owners to disclose in writing the presence of mold to potential buyers or tenants. This last requirement is likely to be dealt with in more detail in the courts, as currently there is no requirement to actually define what is considered unacceptable mold levels.

    In the meantime, building owners need to protect themselves by adopting and documenting a reasonable policy towards addressing mold in their properties. While homeowners could not reasonably be expected to know of the presence of mold in their properties, courts are likely to hold that commercial real estate owners and managers are more sophisticated and should know about the presence of mold. Third party documented mold inspection and monitoring resolves this concern – even if hidden mold is missed there will be evidence of reasonable due diligence.

    Healthy Buildings Approach When Problems are Uncovered

    A question asked by many building owners unfamiliar with Healthy Buildings approach is, “what happens when Healthy Buildings uncovers a major problem in my building? Why should I let a third party open a Pandora’s box of problems where none existed before?”

    This is a very fair question and deserves a full answer. We understand that in fact, no building owner wishes to unknowingly expose his or her tenants to environmental hazards – they would much rather have their tenants work in a safe and comfortable workplace. Moreover, if left untreated, mold can quickly do significant and expensive physical damage to the building’s infrastructure. Should we uncover say, a moldy wall somewhere in a building, most of our clients would much rather that (a) we find it rather then a tenant and (b) the problem be quickly resolved and the solution documented, rather than have the problem fester (or get worse) any longer then necessary.

    Our approach on the rare occasions where we discover significant problems in the buildings we inspect is to work with our clients on devising a solution – have the problem rectified (always by others since we do not sell hardware or remedial services), and document the solution, not just the problem.

    Conclusions

    Building owners adopting Healthy Buildings indoor air quality inspection programs can rest assured that professional, high quality indoor environmental documentation will be on file for their building. Any buyer, litigant or regulator interested in IAQ will find the building management has practiced good due diligence, can comply with current legislation and has practiced a reasonable approach to discovering and rectifying mold just as current legal standards of care indicate.

    Procedures for Dealing with Mold Infestation

    Guidelines from Healthy Buildings for Assessing, Managing and Remediating Mold in your Property.

    We have drawn these guidelines from EPA documents and our experience to assist commercial building managers in dealing with outbreaks of mold. This checklist was designed to highlight key parts of a commercial building remediation and does not list all potential steps or problems.

    Investigate and Evaluate

  • Consider the possibility of mold as you investigate occupant complaints.
  • Once you discover mold, put remediation and the original cause of the mold at the top of your engineering department’s to-do list. This may prevent small problems from becoming large ones.
  • Assess size of moldy area – consider the possibility of hidden mold. Moldy areas less than ten square feet can be remediated with a minimum of professional assistance.
  • Assign someone from your engineering staff to manage medium or large mold problems greater than 10 square feet.
  • Identify source or cause of water associated with mold.
  • Check inside air ducts and air handling unit.

    Communicate with Building Occupants

  • Coordinate with tenant so that they are aware of the problem and that they understand a timely, competent response is underway.

    Plan and Implement Remediation

  1. Ensure you dry wet, non-moldy materials within 48 hours to prevent mold growth.
  2. Select cleanup methods depending on size of problem:

    • Less than 10 square feet of mold, options are: (1) Clean up via wet vacuum (2) Damp wipe (3) High Efficiency vacuum (HEPA) (4) Remove and discard. Minimum of personal protective equipment required (gloves, N-95 respirator, goggles, eye protection).
    • More than 10 square feet of mold; Consider a formal containment area. Professional assistance may be required.

  3. Fix moisture problem and amend maintenance plan to prevent repetition of problem.
  4. Throughout process, consult with your indoor air quality consultant as necessary.
