HPD mold violations: what landlords need to do

An HPD mold violation has a deadline, size thresholds and paperwork. Here's how it works in plain English, and how a licensed assessor helps you clear it properly the first time.

How to clear an HPD mold violation

Fix the moisture source, have the mold assessed and removed by the right licensed professionals for your building, get a post-remediation clearance, then certify the correction to HPD before the deadline on the notice, with the supporting documents. HPD may reinspect to confirm.

  1. Read the notice. Mold violations are HPD order number 550. The notice gives the class, the apartment and room, and the date to certify by.
  2. Find and fix the moisture. A leak, a roof or facade problem, or poor bathroom ventilation. Cleaning without fixing the source is the most common reason mold comes back.
  3. Get an assessment. A licensed mold assessor measures the affected area, finds the likely source and writes a remediation work plan.
  4. Remediate. A licensed remediator does the work to the plan, filing with DEP first where Local Law 61 applies.
  5. Clearance. The assessor checks the work and, for covered buildings, files the post-remediation assessment with DEP within 7 days.
  6. Certify to HPD. Submit the certification of correction with the supporting documents. For Class B and C mold violations in buildings with 10 or more apartments, that includes affidavits from the licensed assessor and the licensed remediator.

Certifying a violation as corrected when it isn't can lead to penalties for false certification, so the documents need to match what was really done.

Violation classes and deadlines

HPD classes mold violations in an apartment by the size of the growth:

ClassMold in the apartmentTime to correct
Class AUnder 10 sq ft in a room90 days
Class B10 to 29 sq ft in a room30 days
Class C30 sq ft or more in a room21 days

Deadlines run from the date the violation is served. A violation that isn't corrected and certified in time can be upgraded to a higher class. Always go by the dates on your own notice.

Which rules apply to your building

3 or more apartments: Local Law 55
Inspect each occupied apartment and all common areas for mold and pests at least once a year, fix the moisture behind it using safe work practices, and respond to complaints. More on Local Law 55
10 or more apartments: Local Law 61
For mold of 10 square feet or more, use a licensed mold assessor and a licensed mold remediator. Owners and their own staff can't do this work themselves.
Before the work: DEP notice
The remediator files the work plan notice with DEP at least two business days before remediation starts.
After the work: DEP notice
The assessor files the post-remediation assessment notice with DEP within 7 days.

Local Law 61 also covers buildings on zoning lots with 25,000 square feet or more of floor area.

How SBG helps

  • Before the visit, we check the building's HPD violation history on NYC Open Data, so no open mold violation gets missed.
  • Mold removal: we do the work to the assessor's plan, file the DEP work plan notice and sign the remediator's affidavit.
  • Assessment and clearance: we inspect, measure, find the source, write the work plan, check the finished work, file with DEP and sign the assessor's affidavit.
  • In writing: every report lists the areas, readings, sources and photos, so your certification is backed by facts.

Questions

How do I clear an HPD mold violation?

Fix the moisture source, have the mold removed by the right licensed professionals for your building, then certify the correction to HPD before the deadline on your notice, with the supporting documents.

HPD mold violations, step by step

When does mold work need licensed professionals in NYC?

Under New York State law, mold assessment and remediation work on projects larger than 10 square feet must be done by companies licensed by the NYS Department of Labor. In New York City, Local Law 61 of 2018 adds that owners of buildings with 10 or more apartments must use a licensed mold assessor and a licensed mold remediator for mold of 10 square feet or more, and file with the Department of Environmental Protection.

Rules for NYC landlords

My apartment has mold. Is my landlord responsible?

In buildings with three or more apartments, NYC Local Law 55 requires the owner to investigate and fix mold and the moisture that causes it, using safe work practices. If your landlord doesn't act, you can report it to 311, and HPD may inspect and issue a violation. A report from a licensed assessor gives you a written record of what's there.

What does Local Law 55 require from landlords?

Owners of buildings with three or more apartments must inspect each occupied apartment and all common areas for mold and pests at least once a year and when tenants complain, fix the underlying moisture using safe work practices, clean vacant apartments before new tenants move in, and give tenants a notice about indoor allergens with the lease.
