Area figures describe 765 buildings holding 27,289 apartments, so check the specific address before you sign: one building's record can sit far from its neighborhood's average. Building age and condition change access, scope and timing for mold remediation work.

The median Boerum Hill apartment building went up in 1908, 23% of apartments sit in buildings from before 1940 (citywide 45.8%), and 14.8% are in buildings of five floors or fewer (citywide 37.1%). Older stock leaves more gaps and moisture paths for pests to use between apartments.

Local Law 55 (the Asthma-Free Housing Act) is one of the strongest tenant protections against mold in the country. For buildings with 3 or more units, landlords are required to proactively inspect for and remediate indoor allergen hazards including mold, pest infestations, and excessive moisture. For buildings with 10 or more units, the requirements are even stricter: any mold-affected area exceeding 10 square feet must be remediated by NYS-licensed mold professionals — not by the building super painting over it. Landlords must also address the underlying moisture source (leaking pipes, roof damage, condensation from poor ventilation) that caused the mold in the first place. If your landlord paints over mold without fixing the moisture source, that is a violation of Local Law 55 and you can file an HPD complaint to trigger an inspection.

Under New York State Labor Law Article 32, the same contractor is legally prohibited from performing both the mold assessment (testing) and the mold remediation (removal) on the same project. This anti-fraud law was enacted specifically to prevent unscrupulous companies from using scare-tactic test results to upsell unnecessary remediation work. In practice, this means you hire one NYS-licensed mold assessor to test, identify the type and extent of mold, and write a remediation plan. You then hire a separate NYS-licensed mold remediation company to perform the actual removal according to that plan. After remediation is complete, the original assessor (or another independent assessor) returns to perform clearance testing confirming the mold has been successfully removed. This two-company structure protects you from being overcharged and ensures objective results.

Mold that significantly impacts your health or makes the apartment uninhabitable can constitute a breach of the Warranty of Habitability, which may give you grounds to break your lease. However, the legal process requires specific steps: first, notify your landlord in writing (email with photos is ideal) describing the mold condition in detail. Give the landlord a “reasonable” time to cure — typically 21 to 30 days for mold remediation. If the landlord fails to act within that period, you may pursue a constructive eviction claim or a rent abatement (a reduction in rent proportional to the loss of use of the affected space). Document everything: photos with timestamps, a professional mold assessment report, copies of all written communication with the landlord, and any medical records if you have developed respiratory symptoms. Consult a tenant rights attorney before vacating — leaving without following the proper legal process can expose you to liability for the remaining lease term.
