Landlord Mold Compliance in NYC – Article 32, Local Law 55 & HPD Violations

The typical Inwood landlord dealing with a mold problem is managing between three and twenty units in a pre-war walk-up built in the 1920s. These buildings have aging plumbing systems, flat roofs with deferred maintenance, basements that took on water during Sandy or Ida, and tenants who have been in the same unit for a decade or more. The mold problem often has a long history by the time a 311 complaint triggers an HPD inspection.

Hiring for it? Our guide to Article 32 for property managers walks through licensing, the assessor-remediator split, what the plan must include and the clearance paperwork HPD expects.

How common is this? In 2025, HPD issued 396 mold violations in Inwood (ZIP 10034), across 128 of the neighborhood’s 368 residential buildings. That’s roughly 1 in 3 buildings in a single year, and 725 mold violations are still open. The full breakdown by class and year is in our Inwood mold data report.

When that HPD inspector shows up, the stakes become concrete: a violation notice with a cure window, fines that escalate if the window is missed, and a legal obligation to use properly licensed parties for the remediation. Landlords who respond quickly with the correct process – Article 32 compliant, documented, with clearance testing – close the violation and move on. Landlords who try to do it cheap or fast, without the licensed assessor and the written scope, create a situation where the violation stays open, fines compound, and a simple job becomes a legal problem.

What Article 32 Requires from Landlords Specifically

For any mold project over 10 square feet in a building with 10 or more units, New York State Article 32 requires:

1. A licensed Mold Assessor to inspect the affected area, identify the extent and likely moisture source, take samples if appropriate, and write a written Mold Remediation Plan. The assessor must be independently licensed – not employed by or financially connected to the remediation contractor.
2. A licensed Mold Remediation Contractor to execute the remediation plan. The same company cannot legally both write the plan and do the remediation. You need two separate licensed entities.
3. A written Mold Remediation Plan in hand before any remediation work begins. Starting work without this document means the work is not Article 32 compliant, and HPD will not accept non-compliant work for a Certification of Correction.
4. Post-remediation clearance testing by an independently licensed assessor, with results from an AIHA-accredited lab. The clearance report is the document that goes into the Certification of Correction package.

Local Law 55 – The Annual Inspection Obligation

NYC Local Law 55 (the Asthma-Free Housing Act, effective 2018) requires landlords of buildings with three or more residential units to proactively inspect every unit annually for mold and pests – not just respond when tenants complain. In buildings with 10 or more units, mold over 10 square feet triggers the full Article 32 process regardless of whether an HPD inspector has issued a violation.

For Inwood’s landlords specifically: the pre-war walk-up stock east of Broadway, with its aging plumbing and basements with Sandy-era legacy moisture, is exactly the building type where Local Law 55 annual inspections are most likely to find mold. Proactive annual inspection – and correction of findings before they escalate to HPD violations – is far less expensive than the violation-and-cure-window process.

The required proactive disclosure: landlords must provide tenants with the DOHMH “Indoor Allergens” fact sheet at lease signing and at each annual renewal. This is a separate obligation from the inspection itself.

What Landlords Must Not Do

The most common mistakes we see from property managers who haven’t navigated this before:

Painting over visible mold without assessment or remediation. This does not close an HPD violation. The mold is still there. The violation stays open. The paint seals moisture in and accelerates the growth behind the surface. HPD has the authority to re-inspect and issue additional violations.

Using a cleaning service rather than a licensed remediation contractor. Bleach and scrubbing does not meet the Article 32 standard for projects over 10 square feet. A cleaning invoice does not satisfy the Certification of Correction documentation requirement.

Using the same company for assessment and remediation. This is not Article 32 compliant and will not produce documentation that HPD accepts for closing a violation.

Starting remediation before the assessor’s written scope is complete. Under Article 32, the written remediation plan must exist before work begins. Starting without it means the work is out of compliance, and the clearance documentation may not be accepted.

How We Work with Landlords and Property Managers

We handle the remediation side. We can connect you with independently licensed assessors who are familiar with the HPD compliance documentation requirements and can prioritize assessments when cure windows are tight. We know what the Certification of Correction package needs to contain, and we produce the remediation documentation in a format that supports it.

For property managers with multiple buildings: a proactive relationship is more efficient than crisis response. We can coordinate annual Local Law 55 inspection support with licensed assessors, help you identify buildings in your portfolio that are at elevated risk based on age and building condition, and establish a remediation protocol that your team can initiate quickly when findings arise.
