NYC Elevator Inspection Requirements: CAT1, CAT5, and the Independence Rule

If your Brooklyn building has an elevator, it carries a compliance obligation with more moving parts than most owners expect: an annual inspection, an annual test, a heavier test every five years, a rule about who is allowed to perform them, and a filing requirement attached to each.

Most of the buildings we manage are walk-ups, where none of this applies. But our portfolio runs up to roughly sixty units, and at the larger end elevators are standard — and elevator compliance is unforgiving in a way that reflects what the equipment is. This is life-safety machinery, and the city treats it accordingly.

The three recurring obligations

Each produces a report that must be filed with the Department of Buildings. This bears repeating because it's where owners lose ground on every one of these systems: the test happening is not the same as the test being filed. A vendor who performed the work and never filed the report leaves you exactly as non-compliant as if nothing had been done, and the penalty lands on the owner, not the vendor.

The independence rule

Here is the requirement that catches otherwise diligent owners.

The periodic inspection must be performed by an agency independent of the company that maintains the elevator. Your maintenance contractor cannot inspect their own work.

The reasoning is obvious once stated. A maintenance company that finds no defects in equipment it maintains is grading its own homework, and the incentive runs exactly the wrong way. The city closes that loop by requiring separation.

In practice, owners violate this by accident and for understandable reasons. One vendor is simpler. One vendor is often cheaper. One vendor already knows the building. So the elevator company that has serviced the device for fifteen years handles "everything," and nobody examines whether "everything" is permitted to include the inspection.

If you own an elevator building, verify that your inspection agency and your maintenance contractor are genuinely separate entities. Not different departments of the same company — separate.

Budgeting for the CAT5

The annual CAT1 is a routine line item. The five-year CAT5 is not, and it surprises owners with predictable regularity.

A CAT5 involves full-load testing of the safety systems, which means more time, more labor, longer device downtime, and a materially higher cost than the annual test. It's also far more likely to surface conditions that require repair — the whole point of a heavier examination is to find what a lighter one misses. So the realistic budget for a CAT5 year is the test plus a contingency for whatever it turns up.

Because the interval is five years, this is exactly the kind of expense that falls out of institutional memory. Buildings change hands. Managing agents change. Nobody on the current team was there for the last one. Then the test comes due, the device needs work, and there's no reserve set aside for it.

We track CAT5 dates as capital planning items for precisely this reason, alongside boiler age and roof condition — the predictable large expenses that only feel like emergencies when nobody was watching the calendar.

Closing out defects

When an inspection or test identifies defects, two things have to happen: the defect gets corrected, and the correction gets affirmed to DOB, typically via an Affirmation of Correction filed within the window the city sets.

Owners consistently complete the first and skip the second. The elevator gets fixed, the invoice gets paid, everyone moves on — and the building's DOB record still shows an open condition, accruing exposure, waiting to surface during a refinance or a sale.

Correction and affirmation deadlines are set by the Department of Buildings and do change, so confirm the current windows that apply to your filing rather than working from a remembered number.

Where this goes wrong in real buildings

The failure patterns we see most:

The management transition. A building changes hands or changes agents, the maintenance contract transfers, and the filing history doesn't. Nobody knows when the last CAT5 was. Any competent handover package includes the device's filing record, not just the vendor contract.

The one-vendor arrangement. Covered above. Simple, comfortable, and non-compliant.

Deferred repairs on an aging device. Elevators in older Brooklyn buildings can limp along for years with conditions that get noted, patched, and re-noted. Each individual deferral is defensible. The accumulation isn't, and it eventually shows up as a modernization project the owner never budgeted for.

The filed-in-an-inbox report. The vendor emails the report. It's read, it's fine, it's forgotten. Nothing goes to DOB.

What a manager should be doing

For elevator buildings, the coordination work is straightforward and entirely delegable: schedule the independent periodic inspection and the annual CAT1 on a fixed calendar, keep the maintenance contractor genuinely accountable to their contract rather than to their own inspection, confirm every report is filed with DOB and not merely received, turn defect lists into scoped and priced repairs promptly, file the affirmation once the work is done, and flag the CAT5 far enough ahead that it can be budgeted rather than absorbed.

What no manager can do is perform the inspection. That has to come from the licensed independent agency — and if a managing agent ever suggests otherwise, that's a serious signal about how they handle the rest of the building's compliance.

If you own an elevator building in Brooklyn and you're not confident the filings are current, schedule a property consultation and we'll review the device's compliance record with you.
