Summary:
NYC DOB Demolition Permit Requirements and Application Process
Before you start swinging that wrecking ball, you need the necessary demolition permits from the NYC Department of Buildings (DOB) to ensure safety and compliance with regulations. Full Demolition Permits are required for complete removal of a building or structure, while Partial Demolition Permits are necessary for removing only a portion of a building or structure.
The permit type depends on your project scope. A demolition permit issued by the NYC DOB is legal authorization required for the partial or complete dismantling or removal of structures within the city. Whether it’s to clear space for new construction, remove unsafe buildings, or conduct renovations, obtaining a demolition permit is critical for ensuring demolition activities are conducted safely and in compliance with applicable regulations.
To get a building permit in New York City, a licensed Professional Engineer (PE) or Registered Architect (RA) must submit an application to the Department of Buildings. You can submit your permit application via the DOB NOW platform.
Required Documentation and Supporting Materials for DOB Approval
To get a demolition permit, you’ll have to present various documents such as an application form filled out, a report on asbestos investigation, safety plan for the site and copies of utility disconnection letters. Signed-off pre-demolition inspection reports are also required. Don’t forget pest control certification and evidence of worker training in accordance with OSHA standards.
Applications for full demolition permits must include utility certifications by the respective utility companies that all gas, electric, water, steam and other service lines have been disconnected, proof of notice to adjoining owners, and certification that the building has been treated effectively for rodent extermination.
The documentation process is extensive but necessary. All full demolition applications require a site safety plan (SSP). If the building to be demolished is a major building, the SSP is subject to DOB review and approval prior to issuance of the DM permit. Missing any required document can delay your permit approval for weeks.
Professional engineers and registered architects must prepare and seal these documents. ALT-1s and ALT-2s must be filed by a PE (Professional Engineer) or an RA (Registered Architect). In some instances some ALT3s don’t require detailed plans and these can be filed by a non-professional. The complexity of your project determines the level of professional involvement required.
Understanding Major Building Classifications and Site Safety Requirements
On Dec. 11, the definition of a major building in the city’s building code changed from 10 stories to seven, or 75 feet, incorporating thousands of additional projects. This means that any major new build, full demolition or interior demolition with mechanical equipment that is seven stories or more will require a site safety coordinator and approved site safety plan.
This change significantly impacts project requirements and costs. Reducing the height requirement for major buildings significantly increases the number of projects subject to site safety requirements. These projects require the development of a site safety plan and daily site monitoring, which increases overall construction costs.
All full demolition (DM) applications require a site safety plan (SSP). If the building to be demolished is a major building, the SSP is subject to DOB review and approval prior to issuance of the DM permit. All other full demolitions must maintain a SSP on site and available to DOB personnel upon request.
The site safety plan isn’t just paperwork—it’s your blueprint for protecting workers and the public. Contractors who have historically built low-rise buildings up to nine stories need to hire a safety consultant to provide full-time safety professionals and obtain approvals for site safety plans and tenant protection plans. Delays in obtaining approvals for a site safety plan prevent contractors from pulling permits.
Don’t underestimate the timeline impact. Job start dates can be pushed back two to three months because contractors failed to obtain an approved site safety plan. Planning ahead for these requirements is essential for keeping your project on schedule.
Asbestos Abatement and Environmental Compliance Requirements
A project may involve the removal or disturbance of Asbestos Containing Material (ACM). Pre-1987 buildings may have plumbing piping and equipment insulated with asbestos, or may contain walls, floors, ceiling tiles, roofing, etc. made with an ACM. These buildings, prior to permit, require an asbestos assessment to determine whether the site is asbestos-free, has a minimally acceptable amount of ACM to not be an Asbestos Project, or requires asbestos abatement per NYC Department of Environmental Protection (DEP) rules and regulations.
The asbestos compliance process is non-negotiable for demolition projects. Full demolition applications require an ACP-5 form with only item 8(d) Entire Building is free of Asbestos Containing Material (ACM) checked, for DOB to proceed with the demolition permit process, with the exception of ATRU permitted simultaneous demo/abatement projects which may be permitted with a V5 variance.
Testing and documentation requirements are strict. In New York City, you’ll need asbestos testing before performing construction works such as tearing down a wall. The process involves certified professionals and specific forms that must be filed correctly.
ACP-5 and ACP-7 Forms: When and How to File
Where the scope of the abatement work is not an Asbestos Project, an Asbestos Assessment Report form ACP-5 shall be submitted to the DEP, and verified by DOB to proceed with obtaining a DOB permit. Where the scope of work does constitute an Asbestos Project, an ACP-7 shall be submitted to the DEP. Upon completion of the asbestos work, DEP issues combination of Asbestos Project Completion forms ACP-21, and/or Asbestos Project Conditional Completion forms ACP-20, which must be submitted to DOB to proceed with the permit process.
The investigator will then file the ACP5 form electronically with the New York City Department of Environmental Protection (DEP) and DOB for you to get a permit for the demolition or remodeling. This electronic filing system streamlines the process but requires proper completion of all fields.
Understanding project classifications is crucial. A large asbestos project involves the disturbance of 260 linear feet or more of ACM or 160 square feet or more of ACM. A small asbestos project involves between 26 and 259 linear feet or 11 to 159 square feet of ACM. A minor asbestos project involves 25 linear feet or less or 10 square feet or less of ACM.
If the samples from your home have friable asbestos, you must file an ACP-7 form with the NYC DEP to declare you have a friable asbestos project. Anyone can submit this form, not just the surveyor, and you don’t have to file it with the DOB once you submit it to the DEP, unlike the ACP-5. After filing, you can begin an asbestos abatement project to eliminate affected materials before the planned renovation or construction works.
The timing of these filings is critical. These regulations include the requirement that the New York City Department of Environmental Protection (DEP) be formally notified at least seven days before abatement activities take place. Plan accordingly to avoid delays.
Professional Requirements and Certified Contractors
Whenever any renovation, repair, modification, or demolition is to occur, the building owner must have a licensed asbestos inspector conduct a survey to determine if asbestos is present. This survey may include “bulk” sampling of pieces of building material.
Workers or contractors who abate (encapsulate, encase, or remove) or disturb ACM in any way are required by NYS law to be licensed. There are nine types of licenses – asbestos handler, restricted asbestos handler, air sampling technician, inspector, management planner, operations and maintenance, supervisor/contractor, project monitor and project designer. To be certified, asbestos workers or supervisors must complete training courses approved by the NYS Department of Health.
Only a licensed contractor should remove and dispose of the asbestos since they have the appropriate tools, such as an asbestos air monitor. This device ensures the asbestos fibers in the air remain below the permitted limit. Once the licensed contractor removes asbestos-containing materials, the surveyor will revisit your home to confirm the asbestos removal and submit the ACP-5. You can then apply for a permit with the Department of Buildings (DOB).
Working with unqualified contractors isn’t just risky—it’s illegal and expensive. The licensing requirements exist to protect public health and ensure proper handling of hazardous materials. Professional contractors understand the complex regulations and can navigate the permitting process efficiently, saving you time and potential violations.
Sidewalk Sheds, Traffic Control, and DOT Permit Coordination
Sidewalk sheds may not be built without the Department’s prior approval and work permits. However, when there’s an immediate threat to safety, owners may build a shed and file a permit application within 24 hours. Other City agencies may need to authorize a shed before the Department of Buildings approves the work permit. For example, the Office of Construction Mitigation and Coordination at the NYC Department of Transportation (DOT) requires a Building Operation Permit for sidewalk sheds that must extend into the street.
The coordination between DOB and DOT is essential for street-facing projects. After receiving DOB Approval for Sidewalk Shed application, applicants must submit all required documents to the Department of Transportation (DOT) Office of Permit Management to obtain a sidewalk shed permit if such shed extends into the public right of way.
Understanding when sidewalk sheds are required prevents costly surprises. A sidewalk shed shall be installed in conjunction with any new building that exceeds 40 feet in height, if the distance between the building’s exterior wall and the public sidewalk is less than or equal to half the height of the structure. A sidewalk shed shall be erected for any vertical or horizontal building enlargement or façade construction occurring at a level in excess of 40 feet above grade. Sidewalk shed is to be installed when any full or partial exterior demolition of a building is occurring at a level exceeding 25 feet.
