HPD lead violation closure — the 21-day workflow.

HPD lead violation classes.

HPD lead-paint violations fall into three classes. Each carries its own correction deadline and exposure to civil penalties:

• Class A — Non-hazardous. 90-day correction window. Typical examples: recordkeeping gaps, minor documentation lapses.
• Class B — Hazardous. 30-day correction window. Typical examples: deteriorated paint without confirmed lead content, missed annual investigation.
• Class C — Immediately hazardous. 21-day correction window. Typical examples: confirmed lead paint hazard in a unit with a child under six, friction-surface lead exposure, missed LL31 inspection where children reside.

Penalties accrue per day after the deadline until certification of correction is filed and accepted. Class C penalties are by far the steepest and can reach into five figures per unit if left open for months.

What an Envirex closure engagement covers.

The full workflow from notice of violation through certification filing:

• Same-week site assessment. An EPA-certified inspector visits the unit, scopes the remediation, confirms the cited hazards, and identifies any additional lead surfaces requiring attention.
• Remediation scope and pricing. Fixed-fee written quote — abatement, encapsulation, friction-surface replacement, or component replacement, depending on the cited hazard. See Lead Abatement.
• Lead-safe remediation. Performed by an EPA Lead-Safe Certified Firm using HEPA negative-air containment where required, with proper tenant protection and protected work practices.
• Independent dust-wipe clearance. Post-remediation dust-wipe clearance by an independent NYS-licensed assessor — not the abatement contractor — to current EPA thresholds (5 / 40 / 100 µg/ft²).
• Certification of correction filing. Envirex prepares and files the certification package with HPD on the owner's behalf, including supporting clearance documentation, photographs and chain-of-custody.
• Document retention. Compliance file delivered to the owner of record for the 10-year retention requirement.

Typical Class C closure timeline.

From the day Envirex is engaged on a Class C violation, the typical timeline is:

• Day 1–2. Intake call, site visit, fixed-fee quote.
• Day 3–7. Remediation mobilization, containment setup, lead-safe work practice execution.
• Day 8–10. Independent dust-wipe clearance sampling, lab turn.
• Day 11–14. Certification of correction package compiled and filed with HPD.
• Day 15+. HPD review and acceptance — civil penalty accrual stops at the certification filing date.

This timeline assumes prompt owner engagement, occupant access, and a single in-scope unit. Multi-unit or whole-building scopes extend proportionally; we run them as coordinated programs with rolling clearance and filing.

Underlying cause — what put the violation there.

Most HPD lead violations trace to one of four root causes:

• Missed annual investigation. See Local Law 1 Compliance.
• Missed LL31 inspection. See Local Law 31.
• Turnover without lead inspection. See Turnover Lead Inspection.
• Deferred maintenance on friction surfaces. Window stools, troughs and door jambs degrade and chalk lead — the highest-risk components in pre-1960 NYC housing.

After closing the immediate violation, Envirex briefs the owner on which of these is driving the issue and scopes the upstream fix so the same violation doesn't recur the following year.
