Before any construction begins in New York City, every project must go through the Department of Buildings (DOB) for review and approval. This ensures safety, compliance, and proper documentation for all work performed. Yet, one of the most common points of confusion among commercial property owners and developers is the difference between filing and permitting. These terms are often used interchangeably, but they refer to two distinct stages in the construction process.
Understanding how filing and permitting differ, and who is responsible for each, can help project owners avoid delays, compliance issues, and unnecessary costs. It also ensures that each step is handled by the right professional, whether it’s an architect preparing drawings or a contractor ready to pull permits and begin construction.
What is Filing?
Filing is the first official step in getting city approval for a commercial construction project. It involves submitting detailed plans, drawings, and documentation to the NYC Department of Buildings (DOB) for review. The goal of filing is to show that the proposed work complies with building codes, zoning regulations, and safety standards before any construction begins.
The architect or engineer of record is responsible for handling the filing. They prepare and submit the necessary documents, communicate with DOB plan examiners, and make revisions if the city requests changes. Filing happens early in the project timeline, well before the contractor begins any on-site work.
Common filing requirements include:
- Architectural drawings and specifications
- Engineering reports or calculations
- Site plans and zoning analyses
- Energy code compliance forms
- Owner and contractor information
Once the DOB reviews and approves the filing, the project receives a job number and work approval. This approval is what allows the contractor to move forward with pulling the necessary permits that authorize physical construction.
What is Permitting?
Permitting is the stage that follows filing and approval from the Department of Buildings. Once the DOB has reviewed and accepted the filed plans, the contractor pulls the permits needed to begin construction. These permits grant legal authorization to perform the specific types of work described in the approved plans.
The purpose of permitting is to ensure that only licensed, insured professionals carry out the work, and that each aspect of the project complies with building and safety codes during construction, not just on paper.
The contractor is responsible for obtaining the necessary permits, though the architect or engineer may assist with documentation or coordination. This step occurs right before construction begins, once drawings have received DOB approval.
Common permitting requirements include:
- Approved DOB job number and plans
- Valid contractor and subcontractor licenses
- Proof of insurance and bonding
- Payment of permit fees (paid by the owner)
- Work site safety plans or special inspections, when applicable
When permits are issued, the project moves from planning to execution. The contractor can then schedule inspections, coordinate trades, and begin construction under the scope of the approved work.
Filing vs. Permitting: Key Differences
Filing and permitting are closely connected, but they serve different purposes and are handled by different professionals. The filing phase is about getting the city’s approval on the design and technical aspects of a project. The permitting phase is about receiving authorization to start the physical work once those plans are approved.
Understanding where one ends and the other begins helps prevent costly delays and compliance issues later on.
Together, filing and permitting create the checks and balances that keep NYC construction projects compliant and ready to build.
Risks of Starting a Construction Project Without the Right Permits in NYC
Starting construction without the proper permits can have serious consequences in New York City. The Department of Buildings enforces strict compliance standards, and unauthorized work can trigger stop-work orders, fines, or even legal action. These issues can delay projects, increase costs, and damage a company’s reputation.
Key risks include:
- Stop-work orders that halt all construction until permits are obtained
- Costly fines and penalties from the Department of Buildings
- Cost overruns and delays in project completion due to additional inspections or required rework
- Voided insurance coverage if unpermitted work leads to damage or injury
- Difficulty obtaining future permits or approvals for the same property
- Legal exposure for property owners and contractors
- Potential safety hazards from unverified or noncompliant work
For commercial property owners and developers, even minor permitting oversights can snowball into expensive, time-consuming setbacks. Ensuring that all filings are approved and permits properly issued before construction begins protects the project, the property, and everyone involved.
Common Permits for Commercial Projects in NYC
Commercial construction projects in New York City usually require multiple permits, depending on the type, size, and scope of work. Each permit ensures the project meets the city’s building, zoning, and safety requirements before and during construction.
The most common permits include:
- General construction permit: Covers the overall scope of work for architectural or interior construction. Structural permits are separate from this.
- Plumbing permit: Required for installation, alteration, or repair of plumbing systems.
- Electrical permit: Needed for new wiring, lighting, or other electrical system modifications.
- HVAC / mechanical permit: Covers installation or changes to heating, ventilation, and air conditioning systems.
- Sprinkler permit: Ensures fire suppression systems meet DOB and FDNY standards.
- Standpipe permit: Required for vertical water systems used for firefighting.
- Sign permit: Needed for exterior or illuminated signage on commercial properties.
- Sidewalk shed/scaffold permit: Authorizes temporary protective structures around construction zones.
- After-hours variance permit: Allows construction to occur outside standard DOB working hours.
- Specialty permits: May include authorizations for elevators, curb cuts, or landmarks approvals, depending on the building’s characteristics or location.
Additional permits may also apply based on project conditions, such as:
- Crane or derrick permits for heavy lifting or hoisting equipment
- Asbestos abatement or environmental permits for renovation work involving hazardous materials
- Temporary equipment permits for items such as fences, chutes, or construction platforms
- Fire Department (FDNY) permits for hot work, storage of flammable materials, or compressed gases
- Special inspections and certificates of occupancy for projects requiring post-construction approval or a change of use
While not every commercial remodel in NYC will require all of these permits, ensuring the correct ones are in place helps prevent compliance issues, safety violations, and costly delays.
