Site Safety Services
Site Safety
New York City's site safety requirements are among the most detailed in the country. Chapter 33 of the NYC Building Code and Local Law 196 of 2017 together establish a layered framework of safety personnel, training, plan documentation, and on-site compliance obligations that apply to most permitted construction and demolition projects. Post & Lintel supports owners, developers, and contractors in meeting these requirements from permit application through project close-out.
Site safety in New York City is not a single requirement — it is a coordinated system of personnel, plans, training, and ongoing documentation that must be in place before construction begins and maintained throughout.
Chapter 33 of the NYC Building Code governs all safety measures required during construction and demolition — covering pedestrian protection, public safety, worker safety, fall protection, hoisting operations, excavation safeguards, and fire prevention. Chapter 33 applies to all permitted construction work in New York City, with additional requirements triggered as project scale and complexity increase.
Local Law 196 of 2017 added mandatory Site Safety Training (SST) requirements for construction workers and supervisors at sites requiring a Site Safety Plan — establishing minimum training hours, SST card requirements, and documentation standards that apply to all workers on covered projects regardless of their trade or employer.
The December 2024 Threshold Change
Effective December 11, 2024, the NYC DOB revised the definition of a "major building" under the NYC Building Code — reducing the height threshold from 10 stories to 7 stories. This change brought thousands of additional projects into the major building framework, triggering Site Safety Manager and Site Safety Coordinator requirements on projects that previously fell below the threshold. Owners and contractors planning projects on buildings between 7 and 10 stories that previously did not require a Site Safety Manager should verify their current requirements under the revised definition.
Construction Superintendent, Site Safety Coordinator, and Site Safety Manager
NYC Building Code Chapter 33, Section 3310 establishes three tiers of required site safety personnel, each applicable at different project scales. The trigger is whichever threshold is crossed first — height in feet or number of stories above grade. Alteration scope and DOB designation can also independently trigger requirements regardless of building height.
Construction Superintendent
Required for demolition and new construction on buildings up to six stories under the post-December 2024 definition, and for covered alteration work. Must be designated on the permit in DOB NOW before construction begins. As of January 2, 2024, a Construction Superintendent may be designated on no more than three active permits simultaneously — reducing to one active permit at a time for major buildings by January 1, 2026. Must hold a 62-hour SST Supervisor card.
Site Safety Coordinator
Required for new construction and major demolition on buildings between 7 and 14 stories or between 100 and 199 feet in height — whichever threshold is crossed first. The SSC must be on site whenever active construction is occurring. Must hold a DOB license as a Site Safety Coordinator and a 62-hour SST Supervisor card. The December 2024 threshold change brought buildings between 7 and 9 stories into this category that previously only required a Construction Superintendent.
Site Safety Manager
Required for new construction and major demolition on buildings 15 stories or taller, or 200 feet or more in height — whichever threshold is crossed first. The SSM must be on site whenever active construction is occurring. Must hold a DOB license as a Site Safety Manager and a 62-hour SST Supervisor card. The SSM walks the site daily, maintains a logbook, signs off on major operations including concrete pours, hoist erection, crane picks, scaffold builds, and demolition phases, and coordinates directly with DOB inspectors.
Project Threshold Summary
| Building Scale | Required Personnel | Site Safety Plan | SST Requirement |
|---|---|---|---|
| Up to 6 stories (post Dec. 2024) | Construction Superintendent | Required (per LL81) | 62-hr SST Supervisor card for CS; 40-hr SST Worker card for all site workers |
| 7–14 stories or 100–199 ft | Site Safety Coordinator + Construction Superintendent | Required | 62-hr SST Supervisor card for SSC and CS; 40-hr for all workers |
| 15+ stories or 200+ ft | Site Safety Manager + Construction Superintendent | Required | 62-hr SST Supervisor card for SSM and CS; 40-hr for all workers |
| Structural concrete operations (any scale) | Concrete Safety Manager (CSM) in addition to above | Required | DOB-approved 30-hour concrete safety course for CSM |
Superintendent Designation Limits
Beginning January 2, 2024, a Construction Superintendent may not be designated on more than three active permits simultaneously. This limit tightens further to one active permit at a time for major buildings by January 1, 2026 under legislation passed by the City Council. The tightening availability of licensed Construction Superintendents is a significant project planning consideration — particularly for smaller projects that may not have previously needed to plan superintendent engagement in advance. Designations must be made in DOB NOW before work can begin, and permits cannot be issued if the designated superintendent is already at the limit.
Site Safety Plans Under Local Law 81 and Chapter 33
Site Safety Plans (SSPs) are mandatory on all jobs requiring a registered Construction Superintendent, as established by Local Law 81 of 2017. The SSP documents how the construction or demolition work will be completed safely — covering pedestrian protection measures, equipment use, fall protection, fire safety, and emergency procedures specific to the project site.
What a Site Safety Plan Must Cover
Under NYC Administrative Code Title 28, Article 110 and Building Code Chapter 33, a Site Safety Plan must be site-specific and address: the sequence of major construction or demolition operations; pedestrian protection including sidewalk sheds, scaffolding, and barriers; fall protection measures for workers and materials; excavation and shoring safeguards; hoisting equipment locations and swing radii; protection of adjacent buildings and properties; fire prevention procedures; emergency procedures and evacuation routes; and contractor coordination where multiple trades are working simultaneously on site.
SSP Approval and DOB Filing
Site Safety Plans must be approved by the DOB before permits are issued for covered projects. Plans are submitted through DOB NOW: Build as part of the permit application package. The DOB reviews for completeness and compliance with Chapter 33 requirements. Common reasons for SSP rejections include missing site-specific elements, incorrect project addresses, formatting issues, or failure to address specific Chapter 33 safeguard requirements. A rejected SSP delays permit issuance for the entire project, making the quality of the initial submission critical to project timeline.
Post-Approval Amendments and Site Safety Releases
When the scope of work changes after SSP approval — changes to demolition sequence, new hoisting equipment, or modified pedestrian protection — an amended SSP must be submitted and approved before the change is implemented. At project completion, removal of required site safety personnel and equipment — including sidewalk sheds and scaffolding — requires a Site Safety Release request through DOB NOW, which is granted after a DOB inspection confirms all work is complete and the site is safe.
Site Safety Training (SST) for Workers and Supervisors
Local Law 196 of 2017 — fully in effect since March 1, 2021 — requires all construction and demolition workers at sites requiring a Site Safety Plan to hold a valid SST card from a DOB-approved training provider. Workers without a current SST card may not enter the jobsite. Employers whose workers are found on site without valid cards face steep fines.
SST Worker Card
Required for all construction and demolition workers at sites with a Site Safety Plan. Must include OSHA 10 training within the previous five years. All 40 hours must be completed through a DOB-approved training provider. Online training is accepted only when actively proctored.
SST Supervisor Card
Required for Construction Superintendents, Site Safety Managers, Site Safety Coordinators, Concrete Safety Managers, and Competent Persons designated by a superintendent. Includes a 30-hour OSHA course plus 32 additional SST training credits approved by the DOB. The SSM credential does not substitute for this card — both must be held independently.
Concrete Safety Manager (CSM)
Required for projects involving structural concrete operations. The CSM must complete a DOB-approved 30-hour concrete safety course. Required in addition to — not instead of — the SST Supervisor card and Construction Superintendent or SSM designation.
Temporary SST Card
Available to new entrants to the NYC construction workforce who have completed an OSHA 10-hour course. Valid for six months from issuance — not a permanent credential. The worker must complete the full 40-hour SST requirement before the temporary card expires to continue working on covered projects.
Verification and Enforcement
SST cards are issued by Certus Holdco Inc. (the DOB's designated card administrator) and verified by DOB field inspectors during site visits. As of February 1, 2023, only NYC DOB Training Connect SST Cards are accepted at construction sites — cards from other systems are not valid. The DOB maintains a Site Safety Construction Map that identifies all sites currently requiring SST compliance; workers can check whether SST applies to a specific address before reporting to the site.
Public and Worker Protections During Construction
Chapter 33 of the NYC Building Code establishes the safeguard requirements that apply to all permitted construction and demolition operations — protecting workers, the public, and adjacent properties. These requirements apply regardless of project size, though additional obligations are triggered as project scale increases.
Pedestrian and Public Protection
Construction work adjacent to public sidewalks, streets, and rights-of-way must be protected with approved measures to prevent injury to the public and damage to property. Required protections include sidewalk sheds (also called scaffolding sheds or covered walkways) for buildings where falling material risk exists, construction fencing at the site perimeter, overhead protection for workers below excavation or overhead work, and flagging or traffic control when construction affects vehicle or pedestrian flow. Each type of protection requires its own DOB and, in most cases, DOT permit before installation.
Fall Protection
Chapter 33 requires fall protection for workers exposed to fall hazards at heights of six feet or more on construction sites — including guardrails, safety nets, and personal fall arrest systems. Specific fall protection requirements apply to floor openings, leading edges, roofing operations, scaffold erection and dismantling, and work on the faces of buildings. Fall protection plans must be developed by a qualified person and be available on site for DOB review.
Hoisting and Crane Operations
Crane and hoisting operations on NYC construction sites are subject to detailed permit, inspection, and safety requirements administered jointly by the DOB and the DOB's Cranes and Derricks unit. Crane permits must be in place before any crane is erected or operated. The SSM or SSC must sign off on crane picks and hoist erection as part of their daily site safety responsibilities. In 2021, Local Law 92 established new requirements for tower crane inspections and ground crew certification.
Excavation and Adjacent Structure Protection
Excavation work within the influence zone of adjacent buildings must be designed and monitored to prevent settlement, movement, or damage to neighboring structures. Chapter 33 requirements for excavation include pre-construction surveys of adjacent buildings, implementation of support of excavation (SOE) systems where required, and monitoring of settlement and vibration during excavation operations. These requirements interact with Special Inspection obligations for soil and foundation work under Chapter 17.
Fire Prevention and Hot Work
Chapter 33 requires fire prevention measures throughout the construction and demolition process — including fire suppression systems on site, fire watch personnel during and after hot work (welding, cutting, and grinding), and coordination with FDNY for high-rise construction sites. On sites requiring an SSM, the SSM coordinates with FDNY for hot-work, gas, and welding operations, and is responsible for ensuring that fire watch requirements are met. High-rise construction sites also require an FDNY Fire Safety Manager (F-89 license) in addition to the DOB-licensed SSM.
Incident Reporting
Under Local Law 78 of 2017, property owners and other responsible parties are required to report construction site incidents to the DOB within three business days using the Injury/Fatality Incident Information Form. Incidents include construction accidents, injuries, fatalities, and structural failures. The SSM or SSC is typically the first point of contact for incident documentation and reporting. Failure to report a covered incident is itself a violation.

Frequently Asked Questions
What changed with the December 2024 "major building" definition?
Effective December 11, 2024, the DOB reduced the major building height threshold from 10 stories to 7 stories. Buildings that are 7 to 9 stories tall — previously requiring only a Construction Superintendent — now require a Site Safety Coordinator. Buildings 15 stories or 200 feet or taller continue to require a Site Safety Manager. This change significantly expanded the number of projects subject to SSC and SSM requirements.
Can the same person serve as both Construction Superintendent and Site Safety Manager?
Not typically. The Construction Superintendent and Site Safety Manager are distinct roles with separate DOB license requirements. On major building projects, both a Construction Superintendent and an SSM (or SSC) must be designated. The SSM credential does not replace the Construction Superintendent designation, and the CS designation does not replace the SSM. Both must be separately designated in DOB NOW.
What does an SSM actually do on site every day?
The licensed SSM walks the site daily and documents conditions in the SSM logbook. They sign off on the start of major operations including concrete pours, hoist erection, crane picks, scaffold builds, and demolition phases. They inspect sidewalk sheds, scaffolding, hoists, netting, and fall protection. They coordinate with DOB inspectors during scheduled and unannounced visits, and with FDNY for hot-work, gas, and welding operations. They have authority to stop unsafe work — including trades not under the general contractor.
What happens if a worker on site doesn't have an SST card?
Workers without a valid SST card may not enter the jobsite. DOB field inspectors verify SST cards during site visits — unannounced inspections are common on covered projects. Employers whose workers are found on site without valid cards face DOB violations and fines. The Construction Superintendent, SSC, or SSM is responsible for ensuring that all workers on site hold valid cards before they begin work.
Is a Site Safety Plan required for alteration projects?
Yes, if the alteration requires a Construction Superintendent under the NYC Building Code. Local Law 81 of 2017 made Site Safety Plans mandatory on all jobs requiring a registered Construction Superintendent — which includes most ALT-1 and major ALT-2 projects, as well as all demolition work. The SSP must be filed and approved through DOB NOW before the DOB will issue the permit.
What is the Construction Superintendent permit designation limit?
Beginning January 2, 2024, a Construction Superintendent may be designated on no more than three active permits simultaneously. This limit reduces to one active permit at a time for major buildings by January 1, 2026. The tightening superintendent availability is a significant project planning constraint — particularly for projects in the 7-to-9-story range newly captured by the December 2024 threshold change. Permit applications designating an over-limit superintendent are rejected by DOB NOW.
When is a Concrete Safety Manager required?
A Concrete Safety Manager (CSM) is required for projects involving structural concrete operations — including cast-in-place concrete slabs, columns, beams, and walls — on projects otherwise requiring a Construction Superintendent, SSC, or SSM. The CSM must complete a DOB-approved 30-hour concrete safety course and hold that credential in addition to the required SST Supervisor card. The CSM is required on any qualifying project that crosses into major building territory under §3310.10.
How is a sidewalk shed released at project completion?
Sidewalk shed removal requires a Site Safety Release request submitted through DOB NOW under +Requests → Site Safety Release and Sidewalk Shed Removal. The release is granted after the DOB conducts an inspection confirming that all required work is complete and the site is safe. Until the release is granted, the shed must remain in place and the associated permit must remain active. DOT permits for the shed must also be closed separately.
