The 2021 partial collapse of a parking garage in lower Manhattan accelerated a city-wide mandate to assess every parking structure in New York — before failure, not after.

What Qualifies as a Parking Structure

Under Local Law 126, a "parking structure" means any building or portion of a building used for parking or storing motor vehicles — including open parking garages, enclosed parking garages, and parking areas within mixed-use buildings. The law excludes unenclosed surface lots without a structural deck, one- or two-car garages serving exclusively one- and two-family dwellings, and auto service stations or showrooms. Owners uncertain about applicability may submit a Verification Request through DOB NOW: Safety to confirm whether their structure is subject to the program.

Filing Windows by Community District

Cycle 1 of the PIPS program runs from January 1, 2022 through December 31, 2027, divided into three sub-cycles by community district. A structure's sub-cycle is determined by the community district in which it is located. The QPSI must submit the condition assessment report within 60 days of completing the inspection, and no more than six years from the submission of the preceding report.

Cycle Frequency Change Starting 2028

Beginning January 1, 2028, the inspection cycle shortens from six years to four years. The DOB has not yet released the specific sub-cycle structure for cycles beginning in 2028. Structure owners should monitor DOB communications as 2028 approaches and engage QRWIs accordingly once the new cycle parameters are published.

New Construction — First Report Timing

For newly constructed parking structures, the initial compliance report must be filed six years from the date of the first Temporary Certificate of Occupancy (TCO), Interim Certificate of Occupancy (ICO), or Certificate of Occupancy (CO). If that date falls outside the structure's applicable sub-cycle window, the report must be filed within the next applicable sub-cycle.

The One-Time Initial Observation

In response to concerns that parking structures in Sub-cycles 1B and 1C could go uninspected for years while awaiting their sub-cycle windows, the DOB adopted 1 RCNY §103-16 in October 2023, effective November 2023. This rule required all Sub-cycle 1B and 1C parking structures to undergo a one-time initial observation — in addition to their standard six-year condition assessment — completed and filed by August 1, 2024.

The initial observation deadline of August 1, 2024 has now passed. Sub-cycle 1B structures that filed a complete, acceptable PIPS condition assessment report under 1 RCNY §103-13 before August 1, 2024 were exempt from the separate initial observation requirement. Sub-cycle 1C structures in the Bronx, Queens, and Staten Island were required to complete the initial observation regardless.

Qualified Parking Structure Inspectors (QPSIs)

All parking structure condition assessments under Local Law 126 must be performed by or under the direct supervision of a Qualified Parking Structure Inspector. Only a QPSI can file compliance reports through DOB NOW: Safety. Structure owners cannot self-file, and general inspectors without QPSI designation are not authorized to conduct these assessments.

QPSI Qualification Requirements

A QPSI must be a New York State licensed Professional Engineer in good standing with the New York State Education Department and the NYC Department of Buildings. In addition to the PE license, the QPSI must have a minimum of three years of relevant experience working with parking structures and must complete a formal certification process administered by the NYC DOB. QRPSIs must maintain insurance coverage per 1 RCNY §101-07 and keep records of all inspections and tests for at least six years, available to the DOB upon request.

Scope of the Condition Assessment

The condition assessment must permit a complete physical examination of the parking structure and all its appurtenances. The QPSI must apply a professional standard of care to evaluate all building systems comprising the structure, including structural components, waterproofing systems, fireproofing and fire-stopping systems, and wearing surfaces. Before the inspection, the QPSI must review the most recent compliance report, all annual observation checklists from the prior cycle, available structural design or repair drawings, any open violations, and applicable FISP reports where the structure is part of a larger building.

Physical examinations must be performed on a minimum of 10% of each structural element type — beams, columns, and slabs — with focus on the most deteriorated locations identified by the QPSI's assessment program. The QPSI may employ load tests, optical surveys, non-invasive scanning, and cores as needed to support the condition assessment. When deficiencies are found, the QPSI must ascertain their cause and order any additional probes or tests required.

Annual Observation Checklist

During the first condition assessment, the QPSI develops a unique annual observation checklist containing baseline items to be inspected during annual observations conducted between the six-year condition assessments. These annual observations — required every year between filings — must also be performed or supervised by a QPSI. This ongoing requirement means that structure owners should maintain a relationship with a QPSI throughout the cycle, not only at the six-year assessment point.

What the Condition Assessment Covers

The PIPS condition assessment is a comprehensive structural and systems review of the entire parking facility. The following elements are evaluated as part of the inspection program developed by the QPSI for the specific structure.

• Structural concrete slabs and decks
• Beams, girders, and transfer structures
• Columns and bearing walls
• Foundation elements (where accessible)
• Ramps and level transitions
• Post-tensioning and prestress systems
• Waterproofing membranes and coatings
• Expansion joints and sealants
• Drainage systems and slope conditions
• Wearing surfaces and traffic coatings
• Spalling and delamination of concrete
• Rebar corrosion and section loss
• Chloride infiltration and salt damage
• Cracking — pattern, width, and depth
• Fireproofing and fire-stopping integrity
• Stair towers and elevator structures
• Façade and exterior envelope elements
• Guard rails and barrier systems
• Lighting and overhead clearance structures
• Mechanical, electrical, and life-safety systems

Safe, SREM, and Unsafe

Following the condition assessment, the QPSI assigns one of three ratings to the parking structure. Each classification carries specific compliance obligations and timelines under 1 RCNY §103-13.

The SREM-to-Unsafe Escalation

A critical enforcement mechanism under 1 RCNY §103-13: any condition reported as SREM in a prior compliance report that remains uncorrected at the time of the current inspection must be reclassified as Unsafe — regardless of whether the physical condition has actually worsened. This automatic escalation is the same principle applied in FISP's SWARMP-to-Unsafe mechanism. Structure owners must treat SREM conditions as active compliance obligations with defined deadlines, not deferred items. A $2,000 one-time penalty applies for failure to correct an SREM condition within the QPSI-recommended timeframe.

Compliance Step by Step

The following outlines the standard sequence for meeting the PIPS condition assessment requirement within the applicable sub-cycle filing window.

Penalties for Non-Compliance

The DOB enforces the PIPS program through a structured civil penalty regime. Sub-cycle 1A and 1B filing windows have both closed — owners in those districts who have not filed are actively accruing penalties and should engage a QPSI immediately.

Late filing of an initial or compliance report carries a penalty of $1,000 per month from the missed deadline. Failure to file a report at all results in a $5,000 per year charge. An additional $2,000 one-time penalty applies for failure to correct an SREM condition within the QPSI-recommended timeframe. For Unsafe conditions, failure to install required public protection or complete repairs within the 90-day window exposes owners to further enforcement action, emergency repair orders issued by the city at the owner's expense, and civil liability exposure in the event of injury or property damage.

If Your Sub-Cycle Window Has Closed Without a Filing

Owners of structures in Sub-cycle 1A (Manhattan CDs 1–7) or Sub-cycle 1B (Manhattan CDs 8–12 and Brooklyn) whose filing windows have closed without an acceptable report on file should engage a QPSI and file as soon as possible to stop ongoing penalty accumulation. Filing late — while subject to accrued penalties — is significantly better than continued non-compliance.

Common Conditions in NYC Parking Structures

Parking structures in New York City face a particularly aggressive set of environmental and operational stresses. The combination of heavy repetitive loading, chloride exposure from road salts tracked in by vehicles, moisture infiltration through deck surfaces and expansion joints, and the freeze-thaw cycling characteristic of the regional climate creates a deterioration pattern that can progress quickly — especially in structures that have not received regular maintenance.

Chloride-Induced Rebar Corrosion

The leading cause of structural deterioration in urban parking structures is corrosion of the embedded steel reinforcement triggered by chloride penetration — primarily from deicing salts. Once chlorides reach the rebar, corrosion begins, producing iron oxides that expand within the concrete section. This expansion generates internal tensile stress that cracks and eventually spalls the concrete cover, exposing the rebar further and accelerating the cycle. Spalling concrete directly above or adjacent to occupied areas is an immediate safety concern.

Waterproofing and Drainage Failure

Traffic-bearing decks rely on waterproofing membranes and protective coatings to prevent water and chloride infiltration into the structural slab. When membranes fail — at cracks, expansion joints, drains, or through wear — water penetrates the deck and begins the corrosion cycle. Clogged or damaged drains allow water to pond on deck surfaces, exacerbating infiltration and accelerating deterioration. Drainage maintenance and periodic recoating of deck surfaces are among the most cost-effective preventive measures for parking structures.

Post-Tensioning System Deterioration

Many post-tensioned concrete parking structures built from the 1960s through the 1990s are now experiencing deterioration of their prestressing systems. Corrosion of post-tensioning tendons — particularly in unbonded monostrand systems — can lead to sudden tendon failure, dramatically reducing the structural capacity of the affected span. Post-tensioning condition is a specific focus of PIPS assessments in structures of applicable construction type.

Expansion Joint Failure

Expansion joints accommodate thermal movement in the structure and are critical waterproofing transition points. Failed, compressed, or missing joint sealants are among the most common deficiencies found in parking structure assessments — and among the most important to address, as joint failures channel concentrated water flow directly into the structural system below.
