SWARMP, Unsafe, and Maintenance: How FISP Severity Categories Work

Every condition observed during a Local Law 11 / FISPinspection must be classified into one of three severity categories. These categories are not suggestions — they are regulatory classifications defined by the NYC Department of Buildings that determine what happens next: how fast repairs must happen, whether the DOB gets involved immediately, and whether the building needs a protective sidewalk shed.

The three categories, in descending order of severity, are Unsafe, SWARMP, and Maintenance.

The Three Categories at a Glance

Unsafe

An Unsafe classification means the QEWI has observed a condition where facade material is at risk of falling onto a public area. This is the most serious classification and triggers immediate regulatory consequences.

What Triggers an Unsafe Classification

• Loose or detached masonry. Bricks, stones, or terra cotta units that have separated from the substrate and could fall.
• Severe spalling with exposed reinforcement. Concrete that has deteriorated to the point where rebar is visible and the remaining material is unstable.
• Displaced lintels or sills. Structural elements above windows or doors that have shifted, cracked, or are no longer properly supported.
• Hanging or detached facade elements. Cornices, fire escapes, window guards, or other appurtenances that are partially detached.
• Active water infiltration causing structural damage. Where water penetration has weakened the facade to the point of material instability.

What Happens After an Unsafe Finding

The QEWI is required to notify the DOB immediately — not at the time of report filing, but at the time of observation. The building owner must:

1. Install protective measures (sidewalk shed, netting, or barriers) to protect pedestrians.
2. Engage a contractor for emergency repairs.
3. Complete repairs within the timeframe specified by the DOB.

An Unsafe finding does not mean the building is condemned. It means one or more specific conditions require immediate attention. The rest of the facade may be in good condition.

SWARMP — Safe With a Repair and Maintenance Program

SWARMP is the middle category and the one most frequently misunderstood. The name is the classification: the facade is currently safe, but only if the building owner implements a repair and maintenance program to address the observed conditions before they deteriorate further.

What Triggers a SWARMP Classification

• Cracking that is not yet structurally critical. Hairline cracks, pattern cracking, or cracks that have not yet caused material displacement.
• Early-stage spalling. Concrete surface deterioration where the substrate is still sound and no reinforcement is exposed.
• Efflorescence. White salt deposits on masonry surfaces, indicating water is moving through the facade but has not yet caused structural damage.
• Deteriorated mortar joints. Mortar that is recessed, crumbling, or missing in localized areas, but the masonry units are still secure.
• Sealant failure at joints. Failed caulking or waterproofing at expansion joints, window perimeters, or through-wall penetrations.
• Corrosion staining. Rust staining from embedded metals (lintels, shelf angles, anchors) that indicates active corrosion but no displacement yet.

The SWARMP Obligation

A SWARMP classification means the building owner must repair the conditions within the current inspection cycle. Unlike Unsafe, there is no emergency notification to the DOB. But the obligation is real: if the conditions deteriorate to Unsafe before they are repaired, the building owner bears the liability.

The QEWI’s report should document the specific repair and maintenance program recommended for each SWARMP condition.

Maintenance

Maintenance is the lowest severity category. It covers conditions that are cosmetic or require routine upkeep but do not present a safety concern and are not expected to deteriorate into a safety concern within the cycle.

What Triggers a Maintenance Classification

• Surface staining. Dirt, pollution deposits, or biological growth (moss, algae) that affect appearance but not integrity.
• Minor paint or coating deterioration. Peeling paint on non-structural elements.
• Cosmetic cracks. Hairline cracks in stucco or parging that do not extend into the structural substrate.
• Normal weathering.Patina, surface erosion, or minor roughening consistent with the material’s age and exposure.

Maintenance conditions do not require DOB notification or a formal repair program. They are documented in the FISP report as part of the overall facade assessment.

How QEWIs Decide Between Categories

Classification is a professional judgment call, not a mechanical process. Two experienced QEWIs looking at the same crack may reasonably disagree on whether it is SWARMP or Maintenance. The DOB expects the QEWI to exercise their professional judgment based on:

• Proximity to failure. How close is this condition to causing material to detach or fall?
• Location. A crack on the 20th floor above a busy sidewalk warrants more conservative classification than the same crack at the second floor above a private courtyard.
• Material type. Terra cotta and prewar ornamental elements may warrant more conservative classification than poured concrete, because they fail differently.
• Rate of deterioration. A condition that has been stable across two cycles is different from one that appeared since the last inspection.
• Context of adjacent conditions. A single crack in isolation is different from the same crack surrounded by efflorescence, corrosion staining, and displaced mortar joints.

The QEWI’s professional license is on every classification they make. Conservative classification (erring toward higher severity) is standard practice — it protects the public and the professional.

Consequences of Misclassification

Under-classifying a defect — calling something Maintenance when it should be SWARMP, or SWARMP when it should be Unsafe — creates real liability:

• If material falls and injures someone, and the FISP report classified the condition below its actual severity, the QEWI’s professional judgment (and license) is exposed.
• The DOB reviews filed reports and can challenge classifications. A pattern of under-classification can trigger an audit of the QEWI’s other filings.
• Building owners who rely on a low classification to defer repairs inherit the liability if the condition worsens.

Over-classifying (calling something Unsafe when SWARMP would be accurate) costs the building owner money — emergency repairs and sidewalk sheds are expensive — but does not create the same professional or public safety risk.

How This Relates to the FISP Report

Every defect in a FISP reportcarries a severity classification. The report must include photo documentation of each defect, its location on the facade, and the QEWI’s assigned severity. The DOB uses these classifications to prioritize enforcement and track the city’s overall facade safety posture.
