What Does NYC Require for Construction Site Fire Safety?
General guidance, not a code determination for any project. Confirm the adopted code and local amendments with the authority having jurisdiction.
New York City (NYC) requires every construction, alteration and demolition site to follow Chapter 33 of both the 2022 NYC Fire Code (FC) and the 2022 NYC Building Code (BC): baseline rules on smoking, waste, hot work, heaters, water and access, plus a certified fire safety manager on major buildings, a standpipe ready once the topmost working deck reaches 75 ft, and a certified watchperson whenever work stops on footprints of 5,000 sq ft or more. The Fire Department of the City of New York (FDNY) issues the certificates and enforces the Fire Code chapter, and the Department of Buildings (DOB) enforces the Building Code chapter through the work permit and the site safety plan.
This article is for owners, general contractors and design teams working in the five boroughs. It sets out what each Chapter 33 requires, where NYC departs from the model International Fire Code (IFC), which agency reviews and enforces each item, and the plans and certified personnel a site needs.
At a Glance: NYC Construction Site Fire Safety
- Jurisdiction: New York City (all five boroughs).
- Local code and edition: 2022 NYC Fire Code Chapter 33 (the Fire Code as amended by Local Law 47 of 2022, in effect since April 15, 2022) and 2022 NYC Building Code Chapter 33, as of November 2026; National Fire Protection Association (NFPA) 241 applies to matters the Fire Code chapter does not address (FC 3301.2).
- Agency (authority having jurisdiction, AHJ): FDNY for Fire Code Chapter 33, certificates of fitness, hot work permits and site inspections; DOB for Building Code Chapter 33, work permits, site safety plans and the site safety manager, coordinator and construction superintendent roles.
- Filing or permit name: a site safety plan that DOB approves before the permit for major building work (BC 3310.3), or one kept on site for jobs with a construction superintendent (BC 3301.13.1); an approved pre-fire plan kept by the fire safety manager (FC 3308.2); FDNY certificates of fitness such as S-56 (Construction Site Fire Safety Manager) and S-60 (Watchperson at Construction Site); FDNY hot work permits under FC 105.6.
- Key difference from the model code: the 2024 IFC has the owner name a site safety director and requires a fire watch in nonworking hours once new construction passes 40 ft; NYC fills both roles with FDNY-certified staff on the sites its thresholds reach, and starts the construction standpipe at a 75 ft topmost working deck instead of 40 ft, with an air-pressurized alarm on any dry riser.
- Review time range (as of November 2026): the general clocks apply. DOB must approve complete, compliant construction documents within 40 calendar days of submission, extendable once by 20 calendar days for good cause (NYC Administrative Code Section 28-104.2.7), and FDNY has 40 calendar days from submission, extendable by 40 (FC 105.2.4).
What Does Chapter 33 Require on a NYC Construction Site?
The Fire Code chapter governs fire safety measures during construction, alteration and demolition (FC 3301.1), and NFPA 241 fills any gap the chapter leaves (FC 3301.2). BC 3301.1.2 requires construction and demolition operations to conform to the Fire Code as well, so the two chapters work as one set: the Fire Code mostly governs how the site operates, and the Building Code sets the site safety program and the physical safeguards.
The Fire Code’s precautions apply to every site. Smoking is banned throughout, including site trailers, with signs at gates, entrances and each floor’s stair and elevator access points (FC 3304.1); combustible waste goes out at least once a day (FC 3304.2); and cutting and welding follow FC Chapter 35 (FC 3304.6). Portable fueled space heaters are barred except for curing and drying under FC 3303, with a certificate of fitness holder personally supervising their use and an FDNY permit (FC 3301.4, 3303.6, 105.6). FDNY can require a fire watch by fire guards at demolition and other unusually hazardous sites (FC 3304.5), and roofing work using a torch or other hot work equipment on roofs of combustible construction is prohibited (FC 3317.4).
Access and water are required from the start. Apparatus access must reach the site and come within 100 ft of each temporary or permanent fire department connection (FDC) (FC 3310.1), and an approved water supply must be available before combustible or hazardous materials arrive (FC 3312.1). The site also keeps portable fire extinguishers, a telephone or approved alternative with the site address and the FDNY emergency number posted beside it, and a first responder box, opened with a citywide standard key, holding the site and hoist keys, the pre-fire plan, permits and logbooks (FC 3315.1, 3309.1, 3319.1).
Fire protection systems stay available to FDNY throughout the work. Standpipes and sprinklers required at construction sites must be provided, maintained and kept available for FDNY use under the Fire Code and construction codes (FC 3313.1, 3314.1), and an existing standpipe stays in service through demolition (FC 3313.2). Only authorized personnel operate sprinkler control valves, under the fire safety manager where one is required, and no portion of a building may be occupied until its required sprinkler system has been tested and approved (FC 3314.2, 3314.3).
Building Code Section 3303 sets the hardware. Once the topmost working deck of a building that requires a standpipe reaches 75 ft above ground, a permanent or temporary standpipe meeting BC Section 905 must be ready for FDNY at all times, serving every floor up to 4 stories or 40 ft below that deck, whichever is less (BC 3303.8, Item 1). Any dry standpipe used during the work carries an air-pressurized alarm system, with the standpipe held at no more than 25 pounds per square inch gauge (psig) (BC 3303.8.1), and once the deck exceeds 75 ft an elevator with Phase I and Phase II recall, or a hoist, must be available to FDNY (BC 3303.12.2). The permanent standpipe is a separate design question, covered in DGA’s guide to NYC’s standpipe requirements under BC 905 and FC 912.
Existing systems get their own rules. In a building under alteration, existing sprinklers are maintained under BC 3303.9, which allows fire protection systems out of service only as the Fire Code permits; during demolition they are kept as nonautomatic systems with risers capped just below the floor being demolished (BC 3303.7.4). Substantially enclosed buildings with footprints of 100,000 sq ft or more need hydrants within 50 ft of the main entrance and at least one per 250 ft of perimeter (BC 3303.7.1.1), and Type IV construction adds measures such as standpipes in the interior exit stairs (BC 3303.7.7).
How Does NYC Differ From the Model IFC Chapter 33?
The 2024 IFC, the model edition under the 2025 New York State Uniform Code, builds its Chapter 33 around a site safety plan approved before the building permit and a site safety director named by the owner (2024 IFC Sections 3303.1, 3303.2). The NYC Fire Code numbers its chapter differently, with the fire safety manager in FC 3308, standpipes in FC 3313 and sprinklers in FC 3314. The table compares the provisions a NYC project team meets most often.
Figure 1: Model Code vs NYC: Fire Safety on a Construction Site
| Topic | 2024 IFC Chapter 33 (model) | 2022 NYC Fire Code and Building Code |
|---|---|---|
| Person in charge of fire safety | Site safety director named by the owner; training and qualifications shown to the fire code official on request (3303.2, 3303.4) | Construction site fire safety manager holding FDNY certificate of fitness S-56 wherever the Building Code requires a site safety manager or coordinator; a separate fire safety manager at 20 or more stories, more than 250 ft or 200,000 sq ft or more of lot coverage (FC 3308.1) |
| Written plan | Site safety plan approved before the building permit is issued, covering access, fire protection equipment, hot work, heating and waste (3303.1, 3303.1.1) | Site safety plan approved by DOB before the permit for major building work (BC 3310.3); pre-fire plan approved and kept on site for FDNY by the fire safety manager (FC 3308.2) |
| Daily inspection | Daily fire safety inspection by the site safety director, with records kept on site until the certificate of occupancy (CO) (3303.3) | Daily inspection by the fire safety manager, recorded in a bound log or approved system (FC 3308.1.1) |
| When work stops | Fire watch in nonworking hours for new construction more than 40 ft above the lowest adjacent grade, or new multistory construction over 50,000 sq ft per story (3303.5.1) | Watchperson with an FDNY certificate whenever work is not underway, from the foundation pour to the CO, on footprints of 5,000 sq ft or more (BC 3303.3) |
| Construction standpipe | In service before construction exceeds 40 ft above the lowest level of fire department vehicle access, extended to within one floor of the highest secured deck (3307.5) | Ready once the topmost working deck reaches 75 ft, serving floors up to 4 stories or 40 ft below that deck, whichever is less; air-pressurized alarm on any dry standpipe (BC 3303.8, 3303.8.1) |
| Water supply | 500 gallons per minute (gpm) with a hydrant within 500 ft once combustible materials arrive; 500 gpm for the standpipe from a hydrant within 100 ft of the FDC (3307.2.1, 3307.4) | Approved water supply before combustible or hazardous materials arrive (FC 3312.1); hydrants within 50 ft of the main entrance and at least one per 250 ft of perimeter on enclosed footprints of 100,000 sq ft or more (BC 3303.7.1.1) |
| Hot work | Chapter 35, with a hot work permit plan in the site safety plan (3303.1.1) | FC Chapter 35, with hot work authorizations supervised by the fire safety manager (FC 3304.6, 3308.5) and FDNY hot work permits under FC 105.6 |
| Fire department access | Vehicle access within 100 ft of every FDC (3307.1) | The same 100 ft rule (FC 3310.1), plus a first responder box holding keys, the pre-fire plan, permits and logbooks (FC 3319.1) |
Two differences change how a NYC site is staffed and built. The first is people: NYC ties fire safety roles to FDNY certificates of fitness, from the S-56 fire safety manager and S-60 watchperson to torch operators, their fire guards and heater supervisors. The second is the standpipe: NYC’s trigger comes later and lets the top outlet trail the deck by up to 4 stories or 40 ft, but its alarm on dry risers stops the site when it sounds (BC 3303.8.1). The model rule and how its 40 ft is measured are explained in DGA’s article on when the IFC requires a standpipe during construction.

Who Enforces NYC Construction Site Fire Safety: FDNY or DOB?
Both agencies enforce, each its own code. FDNY covers the fire safety manager, pre-fire plan, hot work, heaters, fuel gases, fire guards and site access, and issues the certificates of fitness and FC 105.6 permits that go with them. Its hot work permit covers torch work using flammable gas with oxygen and, at any construction site that needs a DOB work permit, flammable gas torches without oxygen and electric arc equipment (FC 105.6).
DOB enforces the Building Code chapter through the work permit. It approves the site safety plan before issuing a permit for major building work (BC 3310.3), certifies site safety managers and coordinators, and applies the standpipe, sprinkler, hydrant, elevator and watchperson rules of BC 3303.
Some Building Code rules need both agencies. Using a standpipe for construction water or compressed air needs FDNY approval, with at least one riser kept for firefighting (BC 3303.8.3); removing a damaged sprinkler system needs a filed application, a professional report and FDNY concurrence (BC 3303.7.4.3); and running a wet standpipe dry in an unoccupied building under alteration needs both commissioners’ approval and an air-pressurized alarm (BC 3303.8, Item 4). The same split carries into the finished building, as DGA’s guide to which NYC approvals belong to DOB and which to FDNY explains.
Which Plans and Certified Personnel Does a NYC Site Need?
Two plans anchor a NYC site. DOB issues no permit for major building work until it approves the site safety plan (BC 3310.3); on other jobs that need a construction superintendent, a plan meeting Article 110 of Title 28 of the Administrative Code stays on site, and the permit holder confirms it to DOB before work starts (BC 3301.13.1). The approved FDNY pre-fire plan is kept on site by the fire safety manager, and FDNY must be told when site changes materially affect it (FC 3308.2).
A dry standpipe adds its own filing. A registered design professional files the alarm system, a licensed master plumber or master fire suppression piping contractor holds the permit, and the plans show the risers, fire department connections, air release, supervisory pressure and pressurization procedures (BC 3303.8.1, Items 3 and 4.11).
The major building definition decides which sites carry the heaviest staffing. Under Local Law 147 of 2021, a major building is 7 or more stories or 75 ft or more, or any building with a footprint of 100,000 sq ft or more, for initial permits issued or requested on or after December 11, 2024, down from 10 stories or 125 ft (DOB service notice, July 8, 2024). Major building work needs a DOB-certified site safety manager, or a site safety coordinator where the Building Code allows one instead (BC 3310).
FDNY’s staffing rule rides on DOB’s. Wherever the Building Code requires a site safety manager or coordinator, the owner must designate a construction site fire safety manager holding FDNY’s certificate of fitness, S-56 on FDNY’s list; the site safety manager may serve, but a separate fire safety manager is required once the building reaches 20 or more stories, more than 250 ft or 200,000 sq ft of lot coverage, counting stories below grade (FC 3308.1). The fire safety manager inspects the site at least daily and logs it in a bound book or approved system, supervises fire guards and hot work authorizations, and handles system impairments under FC 901 (FC 3308.1.1, 3308.5, 3308.6). FC 3308.1 excepts alteration work limited to a facade with no hot work.
Figure 2: Who Runs Fire Safety on a NYC Site, by Building Size
- 320 or more stories, more than 250 ft or 200,000 sq ft of lot coverageA separate S-56 construction site fire safety manager, not the site safety manager (FC 3308.1)
- 2Major building: 7 or more stories, 75 ft or more, or a 100,000 sq ft footprintSite safety manager or coordinator (BC 3310) plus an S-56 fire safety manager, who may be the site safety manager (FC 3308.1)
- 1New buildings, full demolitions, enlargements and other jobs listed in BC 3301.13.3A construction superintendent and a site safety plan kept on site (BC 3301.13.1); FC 3308.1 applies only where a site safety manager or coordinator is required
Other site roles carry FDNY certificates as well. The table lists the certified roles a NYC construction site most often needs and where the rules for each sit.
| Role | Credential | When the site needs one | Where the rules sit |
|---|---|---|---|
| Construction site fire safety manager | FDNY certificate of fitness S-56 | Wherever the Building Code requires a site safety manager or coordinator | FC 3308.1 |
| Site safety manager or coordinator | DOB certificate | Major building work; the Building Code sets when a coordinator may serve in place of a manager | BC 3310 |
| Watchperson | FDNY watchperson certificate (S-60), New York State security guard registration and a construction safety course of at least 10 hours approved by the Occupational Safety and Health Administration (OSHA) | Whenever work is not underway, from the foundation pour to the CO, on footprints of 5,000 sq ft or more | BC 3303.3 |
| Torch operator | FDNY certificate of fitness G-60 (Torch Use of Flammable Gas) | Torch cutting, welding and other torch work with flammable gas | FC Chapter 35, through FC 3304.6 |
| Fire guard for torch operations | FDNY certificate of fitness F-60 | Fire guard duty at torch work | FC Chapter 35; fire guards supervised by the fire safety manager (FC 3308.1.1) |
| Heater supervisor | FDNY certificate of fitness S-92 | Portable fueled space heaters in use for curing and drying | FC 3303.6 |
How Are NYC Construction Sites Inspected and Cited?
FDNY inspects construction sites under the Fire Code’s general right of entry and inspection (FC 104.3, 106.1), and Chapter 33 keeps the key records on site: the approved pre-fire plan, the fire safety manager’s daily log and the first responder box (FC 3308.1.1, 3308.2, 3319.1). FDNY issues notices, orders and violations under Title 15 of the Administrative Code (FC 104.5), may order work discontinued (FC 111) and may revoke permits and certificates of fitness (FC 105.5, 113.9). DGA’s guide to responding to an FDNY summons or violation order covers what each document asks of the owner.
The Building Code adds stop rules through the dry standpipe alarm. When the alarm sounds, FDNY is notified and all work stops until the system is repaired and pressure restored, unless FDNY authorizes otherwise; a concrete pour under way may continue to an orderly shutdown to avoid a cold joint (BC 3303.8.1, Items 4.2 and 4.2.1). A planned shutdown must be back in readiness with the alarm on within 2 hours, or all work stops unless FDNY approves otherwise, and every activation, inspection and repair goes in the site safety manager’s or coordinator’s log where one is required (BC 3303.8.1, Item 5).
Two dates set the current scope. The 2022 Fire Code has applied since April 15, 2022, and the 7-story, 75 ft major building line since December 11, 2024, which brings new buildings of 7 to 9 stories under the site safety manager or coordinator requirement and, through FC 3308.1, the fire safety manager requirement. Facade work keeps its own site safety trigger at buildings more than 14 stories or 200 ft tall (DOB service notice, July 8, 2024).
Figure 3: When Each Fire Safety Duty Starts on a NYC Major Building
Key Takeaway: NYC construction site fire safety runs on two Chapter 33s. The 2022 Fire Code, enforced by FDNY, requires an S-56 construction site fire safety manager wherever DOB requires a site safety manager or coordinator, as a separate person at 20 or more stories, more than 250 ft or 200,000 sq ft of lot coverage, and an approved pre-fire plan on site (FC 3308). The 2022 Building Code, enforced by DOB, requires an approved site safety plan before a major building permit, a standpipe ready from the 75 ft topmost working deck and an FDNY-certified watchperson whenever work stops on footprints of 5,000 sq ft or more (BC 3303.3, 3303.8, 3310.3).
Frequently Asked Questions
When must the standpipe be in service during construction in NYC?
Once the topmost working deck reaches 75 ft above ground in a building that requires a standpipe. From then on, BC 3303.8 requires a permanent or temporary standpipe kept ready for FDNY at all times, serving every floor up to 4 stories or 40 ft below the topmost working deck, whichever is less, and BC 3303.8.1 requires an air-pressurized alarm on any dry standpipe used during the work. The 2024 IFC triggers earlier, before construction passes 40 ft (Section 3307.5).
Who is the construction site fire safety manager?
The person the owner designates under FC 3308.1 to run fire safety on any NYC site where the Building Code requires a site safety manager or coordinator, holding FDNY’s construction site fire safety manager certificate of fitness (S-56). The site safety manager may fill the role, but a separate fire safety manager is required once the building reaches 20 or more stories, more than 250 ft or 200,000 sq ft of lot coverage. The fire safety manager inspects the site at least daily, keeps the log, supervises fire guards and hot work authorizations, and keeps the approved pre-fire plan on site.
Does FDNY inspect construction sites?
Yes. The 2022 NYC Fire Code gives FDNY the right to enter and inspect premises (FC 104.3, 106.1), and Chapter 33 keeps the records FDNY reviews on site: the approved pre-fire plan (FC 3308.2), the fire safety manager’s daily log (FC 3308.1.1) and a first responder box with keys, permits and logbooks (FC 3319.1). FDNY may also order work discontinued under FC 111.
Does a NYC construction site need a watchperson?
Conditional: BC 3303.3 requires a competent watchperson on duty whenever work is not underway, from the foundation pour until the work is complete and a CO or temporary CO is issued, where the building footprint is 5,000 sq ft or more, with one more watchperson for each additional 40,000 sq ft or fraction above 40,000 sq ft. The watchperson needs an FDNY watchperson certificate, a New York State security guard registration and an OSHA-approved construction safety course of at least 10 hours. No watchperson is needed where the building is actively monitored under an FDNY-approved fire safety and evacuation plan.
