How to Fix an UNSAFE Building:
Step-by-Step Guide

What UNSAFE Actually Means

If your building has received an UNSAFE classification under the Facade Inspection & Safety Program (FISP), it means a Qualified Exterior Wall Inspector (QEWI) has determined that one or more conditions on the building's exterior pose an immediate risk to public safety.

This is not a minor maintenance issue. UNSAFE means something on the facade could fall and injure someone. The conditions that trigger an UNSAFE classification include:

• Loose or detached bricks, stones, or terra cotta
• Crumbling or spalling concrete with exposed rebar
• Unstable parapets or copings
• Severely deteriorated mortar joints allowing masonry units to shift
• Cracked or bulging wall sections
• Corroded steel lintels causing masonry displacement
• Detached or unstable fire escape connections
• Any condition where falling debris is a genuine possibility

As of 2026, nearly 2,000 buildings across New York City are classified UNSAFE. Manhattan alone has approximately 1,000 of them. Many have been UNSAFE for years, accumulating penalties that now exceed $100,000 or more. The longer a building remains UNSAFE, the more expensive it becomes to resolve.

Immediate Obligations: The Sidewalk Shed

The first thing that must happen when a building is classified UNSAFE is the installation of protective measures for pedestrians. In nearly all cases, this means erecting a sidewalk shed (also called a sidewalk bridge) along the building's street frontage.

A sidewalk shed is a temporary overhead structure that creates a covered walkway beneath the building's facade. It protects people from falling debris while repairs are being planned and executed. The DOB requires that the shed be installed within 24 to 48 hours of an UNSAFE notification for the most severe conditions, and within a few weeks for less immediately critical situations.

Sidewalk Shed Costs

The sidewalk shed permit must be renewed periodically with the DOB, and the building owner must file justification for keeping the shed in place if repairs extend beyond the initial permit period. The shed cannot be removed until the underlying facade condition has been repaired and the building has been reclassified.

Many buildings in NYC have had sidewalk sheds in place for years because the owners have not completed the required repairs. This is not a cost-effective approach. A shed that stays up for 3 years at $10,000 per month costs $360,000 in maintenance alone, not counting the installation cost or the ongoing DOB penalties.

Step 1: Hire a QEWI

If your building does not already have a QEWI on record, the first step is to hire one. A Qualified Exterior Wall Inspector is a registered architect or professional engineer who has been approved by the DOB to conduct FISP inspections.

The QEWI plays a critical role throughout the entire remediation process:

• Initial assessment: The QEWI performs a detailed close-up inspection to document all unsafe conditions, their locations, and their severity.
• Repair specification: Based on the inspection findings, the QEWI develops a scope of work that describes exactly what repairs are needed.
• DOB filings: The QEWI files all required reports with the Department of Buildings, including the initial FISP report, any amendments, and the final report after repairs are completed.
• Construction oversight: During repairs, the QEWI monitors the work to ensure it meets the specifications and DOB requirements.
• Final sign-off: After repairs are completed, the QEWI inspects the finished work and files a report reclassifying the building.

When selecting a QEWI, look for someone with specific experience in FISP work, not just a general architect or engineer. The inspection requires physical access to the facade via scaffolding or rope access, and the reporting must follow DOB's specific format and filing procedures.

Step 2: File a Repair Plan with DOB

Once the QEWI has completed the inspection and documented all conditions, a repair plan must be filed with the DOB. This plan outlines the specific work that will be done to correct the UNSAFE conditions, the methods and materials to be used, and the estimated timeline for completion.

The repair plan filing is typically handled by the QEWI, but it may also require input from the contractor who will perform the work. The DOB reviews the plan and may request additional information or modifications before approving it.

In addition to the repair plan, the building may need to obtain work permits from the DOB before construction can begin. Common permits required for facade repair work include:

• Alteration permit for structural facade repairs
• Sidewalk shed permit (if not already in place)
• Scaffolding or swing stage permit
• Street closure permit (if work requires closing a lane or sidewalk)

The permitting process can take 2 to 6 weeks depending on the scope of work and the DOB's current processing times. A contractor experienced in FISP work will know which permits are needed and how to expedite the process.

Step 3: Complete the Repairs

With permits in hand, the actual repair work can begin. The scope of facade repairs for an UNSAFE building varies enormously depending on the conditions found, but common repair activities include:

Common Facade Repair Work

• Repointing: Removing deteriorated mortar and replacing it with new mortar. This is the most common facade repair and addresses loose masonry joints.
• Brick replacement: Removing damaged or loose bricks and installing new ones that match the existing facade.
• Lintel replacement: Removing corroded steel lintels (the supports above windows) and installing new galvanized or stainless steel lintels.
• Parapet stabilization: Rebuilding or reinforcing unstable parapets at the roofline.
• Concrete repair: Patching spalled concrete, treating exposed rebar, and applying protective coatings.
• Terra cotta restoration: Repairing or replacing damaged terra cotta elements, which are common on older Manhattan buildings.
• Waterproofing: Applying sealants and membranes to prevent water infiltration that causes future deterioration.
• Fire escape repair: Addressing corroded connections, loose bolts, or structural issues with fire escape attachments.

All repair work must be performed by a licensed contractor. The QEWI should be monitoring the work periodically to ensure it meets the specifications outlined in the repair plan. Any deviations from the approved plan must be documented and may require DOB approval.

Step 4: Get Reclassified

After all repairs are completed, the QEWI performs a final inspection to verify that every UNSAFE condition identified in the original report has been properly addressed. This inspection must be close-up and hands-on, just like the initial inspection.

If the QEWI is satisfied that all conditions have been corrected, they file an amended FISP report with the DOB, reclassifying the building as either SAFE (if no further issues remain) or SWARMP (if minor maintenance items were found that do not pose an immediate safety risk).

The DOB reviews the amended report before accepting the reclassification. In some cases, the department may send its own inspector to verify the conditions. The review process typically takes 2 to 4 weeks after the amended report is filed.

Once the building is reclassified, you can apply to have the sidewalk shed removed. The shed removal requires its own DOB filing and typically takes 1 to 2 weeks to schedule and complete.

Timeline Expectations

How long does it take to go from UNSAFE to SAFE? The answer depends on the severity of the conditions, the size of the building, and how quickly you act. Here is a realistic timeline for a typical UNSAFE remediation:

The biggest variable is the repair construction phase. A building that needs minor repointing and a few brick replacements can be done in 2 months. A building that needs extensive lintel replacement, parapet reconstruction, and concrete repair across all four facades could take 6 months or more.

Weather is also a factor. Certain masonry repairs cannot be performed when temperatures are below 40 degrees Fahrenheit, which can extend timelines for projects that span the winter months in New York.

Cost Ranges

The cost of fixing an UNSAFE building varies widely based on the scope of work, building size, and the complexity of the conditions. Here are realistic cost ranges based on typical NYC projects:

Working With a Full-Service Contractor

The process of remediating an UNSAFE building involves coordinating multiple parties: the QEWI, the DOB, the sidewalk shed installer, the scaffolding company, the repair contractor, and often the building's management company and board of directors. Managing all of these moving parts is one of the biggest challenges building owners face.

This is why many building owners choose to work with a full-service facade contractor that handles the entire process from start to finish. A full-service contractor like Avarga Construction Corp provides:

• QEWI coordination and inspection scheduling
• Sidewalk shed installation and maintenance
• DOB permit applications and filings
• Complete facade repair construction
• QEWI final inspection coordination
• DOB reclassification filing
• Sidewalk shed removal

Working with a single contractor who manages the entire process eliminates the coordination burden and typically results in a faster timeline to reclassification. It also reduces the risk of delays caused by miscommunication between separate contractors, inspectors, and filing agents.
