Maryland real estate guidance
A practical overview for Baltimore-area owners, landlords, agents, and buyers addressing mold and moisture concerns during property decisions.
A new mold regulation law comes into effect on June 1, 2027. Sounds great
The Maryland General Assembly is about to enact strict regulations on mold in both commercial and residential properties. Sounds great, but Maryland will not be using any scientifically established or legally defined standards; there are no legally defined standards in the United States.
Before remediation
New for June 1, 2927 If you own, manage, or flip real estate in Maryland, the legal landscape surrounding property environmental health has changed. Under the Maryland Tenant Mold Protection Act, the clock is officially ticking on how mold and moisture must be legally handled. While basic timeline requirements are already active, June 1, 2027, marks the ultimate shift. By this date, the Maryland Department of the Environment (MDE) will formally enforce strict, uniform statewide standards for mold identification, air sampling, and professional remediation. Whether you manage long-term rentals, clear out bank-owned REO foreclosures, or flip homes, here is what this means for your business—and how to insulate yourself from massive liability. Landlords will be required to perform a mold assessment within 15 days of written notification from a tenant or enforcement agency. Standards for assessment include air sample analysis, analysis of surface Mold remediation must occur within 45 days or a reasonable time frame. Remediation will follow industry guidelines and best practices per Landlords must ensure proper ventilation, maintain low indoor relative humidity, and comply with applicable building and housing codes. This information should be recorded along with procedures followed. Either create a pamphlet for tenants or continue using the EPA's existing “Brief Guide to Mold, Moisture, and Your Home.” https://www.epa.gov/mold
I'm Not An Attorney, But?
Perform preventative moisture checks, install smart humidity trackers, and distribute mandatory MDE mold educational booklets upon lease signing to clearly outline tenant care responsibilities. How do you settle this legally
Watch out for In-housing conflicts, this could cause conflict of interest. When testing is done use caution. Companies doing initial testing and remediation on the same property may create an inherent conflict of interest. Firms may manipulate air samples to increase scope and cost How do you settle this legally
Make certain you get professional company, recieve itemized lists detailing square footage, equipment usage and clear scopes of work.
Practical next steps
Photograph affected areas and note where moisture, odors, stains, or visible growth appear. Keep records of temperature and humidity levels before a legal battle begins. Avoid the legal gaugmire before it starts. Contact a mold specialist before hand to collect records, and conditions.
Often times finding the sources of mold are easy, but not always. Look beyond the surface for leaks, drainage issues, humidity, plumbing concerns, or building-envelope failures. Contact an experienced mold specialist to locate the sources and eliminate them before complaints begin.
Match cleanup and repairs to the condition, the materials involved, and the property's intended use.
Save inspection notes, photos, estimates, invoices, records of climate and humidity,and any reports that explain the work completed.
Real estate and housing obligations can depend on the property, lease, contract, condition, and current Maryland requirements. This page is for general education; speak with a qualified Maryland attorney or the appropriate local authority for advice about a specific situation.
