NYC Plan Examination: Professional Certification vs. Standard Review, Turnaround Times, and Tips

How NYC plan examination works: the difference between professional certification and standard review, current DOB turnaround times, audit risk, and tips to speed approval.
Plan Examination Pathways and Tips
What is the DOB plan examination process?
Plan examination is DOB's review of submitted construction plans for compliance with the NYC Building Code, Zoning Resolution, and other applicable laws. When you submit plans for a standard (non-self-certified) job, DOB assigns a plan examiner who reviews the drawings and documents. The examiner either approves the plans (permitting the permit to be issued) or issues objections that must be resolved. Plan examination can involve one or multiple reviewers from different disciplines (architectural, structural, MEP).
What is the difference between "professional certification" and "standard" plan review?
In standard review, DOB's plan examiners review the plans before the permit is issued. In professional certification (Pro-Cert), the licensed PE or RA self-certifies that the plans comply with all applicable codes, and DOB issues the permit without prior review — but reserves the right to conduct an audit of the certified plans after the fact. Pro-Cert is faster (permits often in days vs. weeks or months for standard review) but carries audit risk.
What is a Pro-Cert audit and what happens if the plans have violations?
DOB randomly audits approximately 20-25% of professionally certified jobs. During an audit, a DOB examiner reviews the plans just as they would in standard review. If the examiner finds code violations in the certified plans, DOB can: revoke the permit, require plan amendments before construction can continue, issue violations against the certifying design professional, and potentially refer egregious cases to DOB's enforcement unit. The certifying professional faces professional discipline risk if they certified non-compliant plans.
What types of projects are not eligible for professional certification?
Certain project types are excluded from professional certification: high-risk occupancies (large places of assembly), buildings with significant structural work, certain job types that DOB has determined require direct review, and any project where a prior approval is required from another agency (these agencies perform their own review). Check DOB's current eligibility rules — they change periodically. An expediter familiar with the current rules can advise on which path is available for a specific project.
What are current DOB plan examination turnaround times?
Turnaround times fluctuate based on DOB staffing and filing volume. For standard review, first-round review for an Alt-2 currently takes approximately 4-12 weeks depending on the borough and job complexity. Subsequent review rounds (after objection responses) add additional time. Alt-1 and New Building applications with full structural review take considerably longer — 3-6+ months is not unusual. Pro-Cert permits can be issued within 1-5 business days of submission (no review before issuance). Check with borough office staff for current wait times.
What tips speed up DOB plan approval?
Tips to speed plan examination: (1) Submit complete, well-organized plans from the start — incomplete submissions get rejected or require multiple correction rounds; (2) Include all required elements on first submission (code compliance schedules, accessibility analysis, energy compliance, egress plans); (3) Use Pro-Cert for eligible projects where speed is critical and the design professional is confident in compliance; (4) Meet with DOB pre-filing for complex or unusual projects — some borough offices offer pre-filing conferences; (5) Respond to objections promptly and completely; (6) Consider a Pre-Application Statement from DCP for zoning-heavy projects.
What is a Pre-Application Statement (PAS) from DCP?
A Pre-Application Statement is a process offered by NYC Department of City Planning for complex zoning matters where an applicant can get DCP's preliminary input on a project's zoning compliance before filing with DOB. Getting DCP's blessing on the zoning analysis can prevent zoning objections from DOB examiners, saving time in plan examination. PAS is most useful for unusual sites, complex FAR calculations, or projects that push the limits of applicable zoning regulations.
Does DOB plan examination cover structural engineering review?
For most Alt-2 projects, DOB's plan examination focuses primarily on code compliance — egress, fire ratings, accessibility, zoning — rather than detailed structural engineering review. For new buildings and major structural alterations, DOB does conduct structural review. However, even where DOB reviews structural plans, the design engineer of record bears professional responsibility for the structural design. Special inspections during construction provide an additional layer of quality assurance for structural systems.
