What Local Law 55 asks owners to do

NYC HPD says owners of buildings with three or more apartments must keep tenant apartments free of mold and pests. The responsibilities include annual inspections for indoor allergen hazards and responding to complaints or inspection findings. Correcting mold means addressing the condition that allowed it to develop, not simply covering the visible mark. Check HPD’s current instructions for notices, safe work practices and violation certification.

When the licensed-contractor requirement matters

HPD states that residential properties with 10 or more units must use a New York State licensed mold assessor and remediator when there is more than 10 square feet of mold. These contractors must be completely independent. Do not turn that threshold into permission to ignore a smaller problem. Other owner duties, safe work practices and New York State requirements may still apply.

Where DEP comes into the job

Local Law 61 covers buildings with 10 or more dwelling units and buildings on zoning lots containing 25,000 or more square feet of non-residential floor area. For covered mold projects, DEP requires online work-plan notification and work-plan filings from the remediation licensee, followed by post-remediation assessment and certification filings from the assessment licensee. Confirm applicability before scheduling work, rather than discovering the filing step at closeout.

Build a usable project file

Keep the complaint or inspection record, leak-repair history, assessment, remediation work plan, contractor information, photographs and final reports together. If HPD issued a violation, follow the actual notice and its certification requirements. A contractor invoice or a passed clearance report is not a substitute for completing every agency step.

A sensible next conversation

Tell the contractor the unit count, approximate affected area, location of the growth and whether a violation is open. Have the owner or managing agent identify who authorizes access, plumbing repairs and reconstruction. This guide is general information, not a determination of legal compliance for a particular property.

Your next-step checklist

  • Confirm unit count and zoning-lot floor area.
  • Identify open HPD notices and deadlines.
  • Separate the assessor and remediation contractor.
  • Confirm required DEP filings and retain receipts.
