Andrew Mitchell works in building restoration at Local Law 11 Brooklyn. He covers facade repair planning, masonry restoration and construction requirements associated with FISP findings.

A lot of people are confused about responsibilities that can cost a building owner time, money and unnecessary stress. I have seen why it matters to know who is inspecting the exterior, who is preparing the repair plan and who is actually carrying out the work.

These responsibilities are connected, but they are not interchangeable. If you are preparing for a facade inspection or planning repairs, here is how I would approach it. In this guide, you'll learn everything you need to know about this topic.

Quick answer: Only a DOB-approved QEWI can perform and file the required facade inspection report. A contractor carries out the physical repairs. An engineer or architect may develop the repair scope and oversee the work, depending on the project's needs and their qualifications.

The QEWI

Who They Are

A Qualified Exterior Wall Inspector, commonly called a QEWI, is a New York State-licensed professional engineer (PE) or registered architect (RA) who meets the New York City Department of Buildings (DOB) requirements for facade inspections and report filing.

Having a professional licence alone does not automatically mean someone is authorised to file these reports. Before engaging anyone, I recommend checking the DOB's current list of approved professionals and confirming their eligibility.

What They Do

The inspection specialist is responsible for evaluating the building's exterior under the applicable inspection requirements. Their work generally includes:

  • Performing the critical examination: Assessing accessible exterior wall areas and identifying deterioration, damage or potentially hazardous conditions.
  • Classifying the facade: Determining the appropriate condition classification based on the findings and applicable DOB requirements.
  • Filing the report: Submitting the required inspection report through DOB NOW: Safety.
  • Updating the record: Filing an amended report when required after relevant conditions have been corrected or the filing needs to be updated.

The inspection is more than a visual check from the pavement. The professional must evaluate the building using appropriate inspection methods and access arrangements for its conditions. One point I always stress is that the findings should guide the next decision.

Repair Design And Oversight

Once inspection findings are available, the building may need a design professional to turn them into a workable construction plan. Depending on the project, this person may prepare a detailed scope of work, specify suitable repair methods, review proposals, answer technical questions and monitor progress.

I recommend having the scope clearly documented before requesting prices. For example, if the building needs masonry repairs and lintel replacement, each bidder should receive consistent information about the affected areas, materials, access requirements and expected deliverables.

Sometimes, the same licensed professional also holds the required DOB approval to carry out the facade inspection. In other cases, the owner engages separate professionals. The right arrangement depends on the building, the scope and the qualifications required for each responsibility.

The Contractor

What We Do

Our role on the construction side is to carry out the agreed repairs safely and in line with the approved scope, applicable requirements and project documents. Depending on the building's needs, this work may include:

  • Masonry repairs and repointing
  • Lintel repair or replacement
  • Parapet repairs
  • Stone restoration
  • Fire escape repair and painting
  • Scaffolding, sidewalk sheds and other access systems

Before work begins, I want the scope, access arrangements, schedule and responsibilities to be clear. That gives the owner and building team a shared understanding of what is included.

During construction, concealed deterioration can sometimes appear after damaged material is removed. When that happens, I recommend documenting the condition, informing the relevant professionals and obtaining approval for any required scope or price change.

Who Does What

Here is a breakdown of the main responsibilities.

Task Inspection specialist Design professional Repair team
Examine and classify the exterior Yes, if DOB-approved Only if also approved No
File required inspection reports Yes, if DOB-approved Only if also approved No
Prepare the repair scope May contribute Often May provide construction input
Carry out physical repairs No No Yes
Document completed work Reviews relevant evidence May review progress Records its work
Address technical questions Within inspection role Within design role Explains construction methods and findings

The precise division of work depends on the building and contract. The key is to establish responsibilities in writing rather than assume that one party will automatically handle everything.

How to Choose

I would approach the selection process in four steps.

1

Confirm the required approval

Check the DOB's current approved list before hiring someone to perform and file the inspection. Ask for clarification if the person's status is unclear.

2

Ask about comparable buildings

Experience with properties of a similar age, height, construction type and condition can be useful. Ask for relevant project references rather than relying on general claims.

3

Review insurance and documentation

Request the appropriate insurance certificates, a written proposal, a defined scope and an explanation of what is excluded. Confirm that the arrangement meets the building's requirements.

4

Consider independent oversight

Some owners prefer separate inspection, design and construction arrangements. This can provide clearer separation of responsibilities, although the best setup depends on the project. Discuss potential conflicts and contractual arrangements with the building's attorney and advisers.

In Brooklyn

Building conditions and access can vary considerably across Brooklyn. Landmark requirements can add another layer of coordination where proposed work requires review. Narrow sidewalks, neighbouring properties, resident access and the placement of protective equipment can also affect planning.

I recommend discussing these conditions before the schedule is finalised. The inspection findings, repair scope, access arrangements and required approvals should all inform the construction plan.

A well-coordinated project starts with clear responsibilities. When the owner, inspection professional, design team and repair crew understand their respective roles, it becomes easier to address problems, document decisions and keep the work moving.

Frequently Asked Questions

Can a construction company perform a Local Law 11 inspection?

Not simply because it carries out facade repairs. The required inspection and filing must be handled by a professional who meets the applicable licensing and DOB approval requirements.

What qualifications should the inspection professional have?

The individual must be a New York State-licensed PE or registered RA in good standing and meet DOB requirements for the filing. Verify current approval before engagement.

Do I need separate people for inspection and design?

Not always. One qualified professional may handle both responsibilities when appropriately licensed and approved. Other projects may benefit from separate specialists.

Who files the amended report?

The DOB-approved inspection professional is responsible for filing the amended report when required. The construction team should provide relevant repair records and supporting documentation.

Can the inspection professional recommend a repair firm?

You can ask for suggestions, but I recommend comparing proposals against the same written scope. Review experience, insurance, exclusions, schedule and pricing before making a decision.

Where can I find an approved inspection professional?

Consult the NYC Department of Buildings' official list of approved QEWIs and verify the individual's current status before signing an agreement.

Need Help Planning Exterior Repairs?

After more than a decade in building restoration, my advice remains simple: establish who is responsible for the inspection, who will define the work and who will carry it out before the project begins.
