DOB NOW: Build represents the technological backbone of the New York City Department of Buildings (DOB), serving as the mandatory online portal for submitting building project applications, obtaining permits, and managing construction-related filings. This platform is the cornerstone of the city’s initiative to digitize the complex landscape of urban development, replacing the legacy Buildings Information System (BIS) with a more transparent, efficient, and accessible digital environment.

For property owners, architects, and contractors operating in the five boroughs, mastering this system is no longer optional; it is the only pathway to legal construction. The platform handles everything from minor residential renovations to the construction of soaring skyscrapers, centralizing financial transactions, plan examinations, and project tracking in a single interface.

Understanding the Transition from BIS to DOB NOW Build

The migration from the legacy Buildings Information System (BIS) to DOB NOW: Build has been a multi-phase process. It is crucial to understand that while BIS remains a repository for historical records and certain ongoing older filings, almost all new applications must be initiated through the Build portal.

Specifically, new building (NB) applications, major alterations (Alt-CO), and a wide array of specialized trade filings—including electrical, plumbing, mechanical, and elevator work—are now exclusively housed within DOB NOW. Users attempting to research a project must often check both systems: BIS for historical context and property profiles, and DOB NOW for active, contemporary filings. Projects initiated in the Build portal will not appear in the BIS database, marking a clear technical boundary between the past and the present of NYC permitting.

Who Are the Authorized Users of the Portal

The system is designed with specific roles and permissions to ensure that only qualified professionals and verified stakeholders can submit documents that impact public safety.

  • Design Professionals: Registered Architects (RA) and Professional Engineers (PE) are the primary users who initiate job filings. They are responsible for certifying plans and ensuring compliance with the NYC Building Code and Zoning Resolution.
  • Licensees and Registrants: This group includes Master Plumbers, Licensed Electricians, General Contractors, and High-Pressure Boiler Operating Engineers. They use the portal to "pull" permits after a job filing has been approved.
  • Property Owners: Owners must have an account to electronically sign applications and authorize professionals to act on their behalf. The system ensures that owners are notified of every major milestone in the project lifecycle.
  • Filing Representatives: Often referred to as expeditors, these professionals manage the administrative aspects of the filing, coordinating between the design team and the DOB plan examiners.
  • Special and Progress Inspectors: These users document the inspections required throughout the construction process to verify that the work matches the approved plans.

The Foundation of Access: Registering for an NYC.ID

Accessing the portal requires a centralized digital identity known as an NYC.ID. This is a single sign-on account used across various New York City government services. It is distinct from IDNYC, which is a physical government-issued photo identification card.

The Registration Logic

Starting in June 2024, the security protocols for accessing the portal were tightened. New users must go to the official registration page to create an NYC.ID using a valid email address. For professionals who previously used the old eFiling system, it is vital to use the same email address associated with those legacy records. Failure to do so will result in a "split" profile, where the user cannot see their historical filings on the new dashboard.

Troubleshooting Email Conflicts

A common issue encountered by users is the "email already in use" error. This typically occurs because the user has already registered for an NYC.ID for another city service, such as the Landmarks Preservation Commission’s portal or a COVID-19 related service. In such cases, the user should not create a new account but instead use the "forgot password" feature to regain access to the existing NYC.ID and then link it to their DOB profile.

A Deep Dive into Permit and Filing Types

Understanding which category a project falls under is the most critical step in the filing process. Choosing the wrong type can lead to months of delays and wasted filing fees.

New Building (NB)

This is for the construction of an entirely new structure from the ground up. These filings are the most document-intensive, requiring exhaustive zoning analysis, energy compliance reports, and structural calculations. Every NB filing eventually leads to the issuance of a new Certificate of Occupancy (CO).

Alteration Type 1 (Alt-1)

An Alt-1 permit is required when the scope of work is significant enough to change the building’s use, egress, or occupancy classification. For example, converting a single-family home into a two-family dwelling or transforming a commercial warehouse into residential lofts requires an Alt-1. Like the NB filing, this results in a new or amended Certificate of Occupancy.

Alteration Type 2 (Alt-2)

The Alt-2 is the most common filing for standard commercial tenant improvements and residential renovations. It covers work that does not change the building's occupancy or use. If an office needs a new layout, or an apartment requires a complete kitchen and bath renovation, an Alt-2 is the appropriate vehicle. These jobs conclude with a Letter of Completion (LOC) rather than a new CO.

Alteration Type 3 (Alt-3)

These are for minor, single-trade alterations that do not involve complex structural changes. Examples include installing a construction fence, a sidewalk shed, or a simple curb cut. In some limited cases, these may be filed by owners, though professional guidance is usually recommended to ensure code compliance.

The Lifecycle of a Job Filing in DOB NOW Build

The process of moving from a concept to a legal permit follows a structured workflow within the portal.

1. The Pre-Filing Stage (PW1)

The process begins with the Plan Work Application (PW1). The design professional enters the scope of work, property details, and applicant information. At this stage, the system calculates the initial filing fees based on the project's estimated cost or square footage.

2. Document Uploads and Electronic Signatures

Once the PW1 is saved, the portal generates a list of "Required Documents." This may include architectural drawings, site safety plans, and technical reports (TR1, TR8). All stakeholders, including the owner, must log in to provide their electronic signatures.

3. Plan Examination and Objections

For projects that are not "Professionally Certified," a DOB plan examiner will review the submission. If the examiner finds code or zoning violations, they will issue "Objections." The portal allows professionals to view these objections in real-time and schedule virtual meetings with the examiner to resolve the issues.

4. Approval and Permit Issuance (PW2)

Once the plans are approved, the designated contractor must log in to the portal to submit the Work Permit Application (PW2). The contractor must ensure their insurance and license are up to date within the DOB system. After the PW2 is processed, the work permit can be printed directly from the portal and must be posted at the construction site.

5. Post-Approval Amendments (PAA)

Construction rarely goes exactly according to the initial plan. If changes are made to the scope of work after the permit has been issued, the design professional must file a Post-Approval Amendment (PAA). This ensures that the final built state of the building matches the official city records.

Technical Specifics for Specialized Work Types

The portal manages different construction disciplines through specialized modules. The rules for these modules can be highly specific.

Foundation (FO) and Earthwork (EA)

Foundation work (FO) encompasses deep foundations, retaining walls, shallow foundations, tie-backs, and anchors. Earthwork (EA) involves excavation and fill operations. While these are often related, the portal treats them as separate work types. If a project involves "underpinning" (digging beneath the foundation of an adjacent building), it must be filed under the FO category. The system does not allow underpinning to be combined with other subcategories in the same filing due to the high-risk nature of the work.

Support of Excavation (SOE)

SOE filings involve the structures built to hold back the earth during deep excavations. Because these filings require review by a special technical team within the DOB, they cannot be combined with general construction (GC) or foundation filings. They must be submitted as standalone applications to ensure a dedicated safety review.

Mechanical and Plumbing Systems

Separate filings are required for plumbing (PL), sprinkler (SP), and standpipe (SD) systems. Each of these must be filed by a licensed Master Plumber or Fire Suppression Contractor. The portal tracks the progress of these trade-specific filings independently, even if they are part of a larger alteration project.

The 2025 Financial Landscape: Fees and Payments

Effective December 21, 2025, under Local Law 128 of 2024, the DOB implemented a new fee structure and payment schedule. These changes are designed to reflect the administrative costs of managing New York’s densifying built environment.

Minimum Fees and Sliding Scales

The minimum permit fee has been raised to $130. For new buildings, the fees are calculated per square foot. For example, a new building with 7 or more stories or exceeding 100,000 square feet now carries a rate of $0.45 per square foot, with a minimum fee of $290. Alterations are typically charged based on the estimated construction cost, utilizing a sliding scale that increases with the project's complexity.

Staggered Payment Rules

A significant change in the 2025 regulations is the timing of payments. For non-electrical work that results in a new or amended Certificate of Occupancy (such as NB or Alt-1 jobs), 50% of the total fee is due at the time of filing, and the remaining 50% must be paid before the permit is issued. For renovations that do not change the occupancy (Alt-2), the full 100% of the fee is now due at the initial time of filing. Electrical permits also follow a 50/50 split, with the second half due before the final inspection.

Tracking Project Milestones and Public Transparency

One of the primary benefits of the digital portal is the increased transparency for the public and industry professionals.

  • Public Portal Search: Any individual can search the public portal without an account to view the status of filings, search for permits by address, and see if there are any active stop-work orders on a property.
  • Automated Notifications: The system sends automated emails to the owner and the applicant of record whenever a project reaches a milestone, such as plan approval, permit issuance, or the signing off on a Letter of Completion.
  • Open Data Integration: The data from these filings is exported daily to the NYC Open Data portal. This allows researchers and developers to analyze construction trends across the five boroughs, including permit volumes and geographic hotspots of development.

Strategic Tips for a Smooth Filing Experience

Navigating the portal effectively requires more than just technical knowledge; it requires strategic planning.

  • Verify Licenses Early: Before starting a filing, ensure that all participating contractors have active licenses and updated insurance certificates on file with the DOB. An expired insurance policy can halt a permit issuance for weeks.
  • Browser Compatibility: The portal is optimized for specific browsers. Enabling pop-ups is essential, as many of the payment windows and document viewers open in secondary windows.
  • Consistent Data Entry: Ensure that the address and Borough-Block-Lot (BBL) information exactly match the records in the Department of Finance (DOF) database. Discrepancies here can trigger administrative objections that are tedious to resolve.
  • Use the Help Desk: The DOB NOW help desk is the primary channel for resolving technical glitches, such as buttons not appearing or documents failing to upload. When contacting them, always provide the specific Job Filing Number for faster resolution.

Conclusion

DOB NOW: Build has fundamentally changed how construction is regulated in New York City. While the transition from paper-based legacy systems to a comprehensive digital portal has introduced new complexities, the result is a system that offers greater accountability and transparency. By understanding the nuances of NYC.ID registration, the specific requirements of different alteration types, and the updated 2025 fee structures, industry professionals can minimize delays and ensure their projects move from the drawing board to the construction site with greater predictability. As the city continues to update the portal with new modules, such as those for green roofs and solar energy storage, staying informed on the latest system updates remains a critical component of professional practice in NYC.

Frequently Asked Questions

What is the difference between NYC.ID and IDNYC?

NYC.ID is a digital account used to log into city websites and services like DOB NOW. IDNYC is a physical identification card for New York City residents. You need an NYC.ID to use the portal, not an IDNYC card.

Can I file a foundation and earthwork application together?

While they are related, they are separate work types in the portal. However, they can sometimes be combined if they are part of a General Construction (GC) filing. If the project involves underpinning, it must be filed strictly under the Foundation (FO) work type.

What should I do if my email is already in use for NYC.ID?

Do not create a new account. Use the "forgot password" option to gain access to the existing account associated with that email. You can then use those credentials to log into the DOB portal.

Are fees refundable if a project is canceled?

Generally, filing fees are non-refundable once the application has been processed or reviewed by a plan examiner. Under the new 2025 rules, the initial 50% payment for major projects is considered a processing fee for the plan examination phase.

How do I see my old projects that were filed in BIS?

Projects filed in the legacy BIS system will not appear on your DOB NOW dashboard. You must continue to use the BIS property search tool to view the history and status of those older applications.
