Facade Inspection Guide: What Inspectors Look For & Common Findings

What Is a Building Facade?

The facade is the complete exterior envelope of a building — every surface, element, and component that makes up the outer skin. In the context of FISP and NYC Local Law 11, "exterior wall" includes not just the primary cladding (brick, stone, concrete, glass curtain wall) but also all appurtenances: cornices, lintels, parapets, balconies, fire escapes, window surrounds, copings, sills, and any decorative elements attached to the building's exterior.

In NYC's pre-war building stock — predominantly masonry construction dating from the late 1800s through the 1940s — the structural frame and the facade are deeply interdependent. Facade deterioration in these buildings is not merely cosmetic; it is structural.

Elements Examined During FISP

A QEWI conducting a current FISP inspection must evaluate all of the following:

Masonry — Brick, Stone & Terra Cotta

The primary cladding material. Inspectors look for spalled faces, missing or crumbling mortar joints (repointing deficiency), delaminated veneers, bulging of the outer wythe, and deteriorated terra cotta medallions, cornices, or decorative elements. Pre-war terra cotta is particularly vulnerable — anchors corrode, causing entire sections to become loose.

Lintels & Shelf Angles

Lintels are structural steel or stone members spanning above window and door openings, carrying the masonry load above. Shelf angles are steel angles bolted to the building's structural frame at each floor, supporting the weight of the facade above each story. Both are embedded in masonry and prone to corrosion. Corroded lintels and shelf angles cause the classic "stair-step" cracking pattern in masonry above openings.

Parapet

The parapet is the portion of the wall that projects above the roof level. It is exposed to weather on three sides (front, back, and top) and is among the most deteriorated elements in older buildings. Inspectors look for movement, overturning (out-of-plumb), open head joints, deteriorated coping stones, and missing or failed through-wall flashing at the base of the parapet.

Balconies & Fire Escapes

Structural balconies are cantilevered concrete or steel elements — their connection to the building frame is a critical inspection point. Inspectors look for rebar corrosion at the slab edges, cracking at the cantilever root, and deflection. Fire escapes must be inspected for corrosion of brackets, platforms, and bolted connections to the building facade.

Sealant Joints & Expansion Joints

Sealant joints between precast panels, at window perimeters, at building expansion joints, and at transitions between dissimilar materials must be flexible and watertight. Failed sealant allows water infiltration that causes freeze-thaw damage, corrosion of embedded steel, and interior water damage. FISP requires inspection of all sealant joints within arm's reach during close-up inspection.

Curtain Wall Systems

Modern buildings with aluminum and glass curtain wall systems require inspection of mullion anchors, glass bite adequacy, weep hole drainage, and thermal break integrity. Older aluminum curtain walls from the 1960s–1980s are often showing their age with failed structural silicone, corroded anchors, and cracked gaskets.

Common Distress Patterns & What They Indicate

The Sounding Technique

Sounding is one of the oldest and most reliable non-destructive evaluation methods in facade inspection. By tapping the facade surface with a hammer or dragging a chain across masonry, the inspector listens for the characteristic hollow sound that indicates delamination or lost bond. A properly bonded masonry surface produces a dense, solid "thud." A delaminated area produces a higher-pitched, hollow "ring" — immediately detectable by an experienced inspector.

Sounding requires physical contact with the facade surface, which is why close-up access (not just binocular observation from the ground) is mandatory under FISP rules. Drone imagery alone cannot adequately detect delaminated areas — sounding of any identified suspect areas must still be performed manually. When delaminated areas are found, they are marked and documented, and their extent must be mapped to determine whether they constitute an Unsafe condition.

Safe, SWARMP & Unsafe Explained

The three FISP classifications carry specific regulatory and practical implications. Understanding them precisely helps property owners plan their response:

• Safe: No conditions pose a danger to public safety within the current inspection cycle. The inspector may note observations or maintenance recommendations, but no mandatory repair timeline is triggered.
• SWARMP: Conditions exist that require repair but do not pose an immediate hazard. The owner must complete the work and file any required follow-up documentation under the current FISP rules. If the work is not completed and documented on time, the building can face escalated enforcement or reclassification.
• Unsafe: Conditions pose an immediate threat to public safety. The inspector must notify DOB promptly. The owner must put protective measures in place immediately and follow the active repair and reporting requirements without delay. If unsafe conditions are not stabilized and corrected, DOB may escalate enforcement and pursue emergency action at the owner's expense.

After the Inspection: Filing & Repairs

Following the close-up inspection, the QEWI prepares the Technical Report (TR6) and files it electronically through DOB NOW. The report must be filed before the building's current filing window closes. If Unsafe conditions were found, an Unsafe classification is entered immediately — do not wait for the report to be fully drafted before notifying the owner of Unsafe findings.

For SWARMP repairs, the typical sequence is: retain a facade contractor → contractor prepares repair plan → QEWI reviews and approves plan → repair work executed → QEWI performs final inspection → follow-up TR6 filed confirming repair completion.

For Unsafe conditions: erect protection immediately → retain contractor → PE-stamped repair drawings prepared (required for structural repairs) → DOB permit obtained → repair work executed → QEWI final inspection → TR6 update filed.

Typical Repair Cost Drivers

Facade repair pricing in NYC varies widely. The main cost drivers are:

• Access method, sidewalk protection, and staging complexity
• The quantity and severity of masonry, lintel, shelf-angle, parapet, or concrete repairs
• Whether the work can be bundled into a single mobilization or must be phased
• The need for structural repair drawings, permits, mockups, or specialty restoration materials such as terra cotta
• How urgently the work must proceed because of an Unsafe or active enforcement condition
