Maryland’s New Multifamily Mold Remediation Laws: What Property Managers Need to Know

Tri State Restorations is Ready to Help You Stay in Compliance

Effective Oct. 1, 2025, significant updates to Maryland’s landlord-tenant laws — including Senate Bill 856 (2024), titled the Maryland Tenant Mold Protection Act, and corresponding additions to the Maryland Tenant Bill of Rights — established new statewide standards for how landlords and property managers must respond to tenant reports of mold in rental housing.

According to Senate Bill 856, enacted during the 2024 Maryland General Assembly session, property owners must test for mold within 15 days of receiving written notice from a tenant and, if mold is confirmed, complete remediation and correct the underlying cause within 45 days, or within a reasonable period if delays are unavoidable. (Maryland General Assembly, SB0856 (2024))

The state’s Tenant Bill of Rights, published by the Maryland Department of Housing and Community Development, reinforces these provisions and requires landlords to keep tenants informed of test results and remediation progress throughout the process. (Maryland DHCD: Tenant Bill of Rights)

Key Provisions of the New Law

Mold Testing Deadline: Landlords must arrange mold testing or assessment within 15 calendar days after receiving written tenant notice.
Remediation Timeline: If mold is confirmed, remediation and source correction must occur within 45 days.
Tenant Transparency: Landlords must share written results and updates with tenants and maintain documentation of compliance.

These regulations apply to multifamily housing, apartment complexes, and condominium units across Maryland. Property owners who fail to comply could face penalties, tenant claims, or enforcement action under state housing standards.
