What Is a QEWI? The Qualified Exterior Wall Inspector, Explained

A QEWI— Qualified Exterior Wall Inspector — is the licensed professional responsible for inspecting building facades under NYC Local Law 11 / FISPand filing the resulting report with the Department of Buildings. The QEWI’s professional stamp is on every filing. Their judgment determines whether a condition is classified as Unsafe, SWARMP, or Maintenance— and those classifications carry legal weight.

Who Qualifies as a QEWI

A QEWI must hold one of two professional licenses issued by the New York State Education Department (NYSED):

• Professional Engineer (PE) licensed in the State of New York, or
• Registered Architect (RA) licensed in the State of New York.

There is no separate “QEWI license.” The qualification comes from holding a valid PE or RA license and performing facade inspections under FISP. The DOB does not maintain a separate registry of QEWIs — any licensed PE or RA can perform the work, though in practice most specialize.

What a QEWI Does

The QEWI’s scope covers the full inspection-to-filing lifecycle:

1. Physical inspection. A close-up examination of all exterior walls and appurtenances (cornices, fire escapes, window guards, balconies, and other projecting elements). This typically involves a combination of ground-level observation, scaffolding or swing-stage access, and increasingly, drone photography.
2. Defect identification and classification. Every observed condition is documented and classified as Unsafe, SWARMP, or Maintenance. This is where professional judgment matters most.
3. Photo documentation. Each defect must be photographed and its location recorded relative to the facade. For a 20-story building, this can mean 200 or more individual frames.
4. Report preparation.The QEWI assembles the findings into a FISP-compliant report — building identification, facade elevations, defect inventory with severity classifications, photo evidence, and repair recommendations.
5. DOB filing.The report is submitted through DOB Now with the QEWI’s professional certification. See How to File an LL11 Report.
6. Unsafe notification.If any condition is classified as Unsafe, the QEWI must notify the DOB immediately — not at the time of filing, but at the time of observation.

How QEWIs Charge

Pricing varies significantly by building size, facade complexity, access method, and the QEWI’s practice. Typical ranges:

• Small buildings (6–10 stories, simple facade): A few thousand dollars for the full inspection and filing.
• Mid-size buildings (10–20 stories): Several thousand dollars, depending on facade material, number of elevations, and access requirements.
• Large or complex buildings (20+ stories, landmarked, curtain wall, extensive ornament): Can run into five figures for the inspection alone, before scaffolding or swing-stage costs.

Most QEWIs bill on a per-building basis, not hourly. The total cost to the building owner includes the inspection, report preparation, and filing. Access costs (scaffolding, swing stage, drone operator) are typically billed separately.

The Bottleneck: Photo Review

Experienced QEWIs often describe the physical inspection as the straightforward part. A practiced inspector can examine a building’s facade in a day. The bottleneck is what follows: reviewing the photographic documentation frame by frame, classifying every defect, mapping defect locations to the facade, cross-referencing against the prior cycle’s report, and assembling the filing.

For a working QEWI running 30 to 100 buildings per cycle, this review and documentation step is the constraint on throughput. Each building can take most of a week of office time. That’s the math that makes facade inspection a capacity-limited business — and it’s the specific step where technology can compress the timeline without replacing the professional judgment.

How Many QEWIs Are Active in NYC

There is no public count of QEWIs. Any PE or RA licensed in New York State can perform facade inspections, but in practice the number who do so regularly is small. Qualitative estimates from industry participants suggest roughly 300 to 400 engineers and architects actively file FISP reports in a given cycle, inspecting the city’s roughly 14,000 facade-obligated buildings.

This concentration means the average active QEWI handles 35 to 50 buildings per cycle. High-volume firms may run 100 or more. The economics of the profession are driven by throughput: more buildings per cycle means more revenue, but only if quality and documentation standards hold.

For Building Owners: How to Find a QEWI

If you own or manage a building that is six or more stories tall, you are required to hire a QEWI for your Cycle 9 filing. There is no central DOB directory of QEWIs, but you can find one through:

• Professional associations. The American Society of Civil Engineers (ASCE) NYC Metropolitan Section, AIA New York, and the New York State Society of Professional Engineers (NYSSPE) can provide referrals.
• Your property manager or management company. Most management companies maintain relationships with QEWIs and can recommend one.
• Prior cycle reports.If your building had a FISP report filed in a prior cycle, the QEWI who filed it is named on the report. Continuity can be valuable — they already know your building.
• Referrals from facade restoration contractors. Contractors who perform facade repairs work with QEWIs daily and can recommend inspectors they trust.

What to Look For

• Active PE or RA license in New York State (verify on the NYSED website).
• Experience with your building type (prewar masonry, curtain wall, terra cotta, etc.).
• Familiarity with the DOB Now filing system.
• Clear pricing — per building, with access costs itemized separately.
• Willingness to explain their findings in plain language, not just hand you a filing.
