New York City permitting, the figures
The key published figures for this jurisdiction — each cited to its official source.
What the data shows
The average time from filing to approval in DOB NOW rose to 20.2 days in FY2024, an 11% increase over the prior year's 18.1 days (NYC Mayor's Management Report, FY2024).
DOB attributes most elapsed time to the applicant rather than the agency, stating time with the applicant is typically three times as long as the time the filing is with the Department for review (NYC Mayor's Management Report, FY2024).
More than 107,000 jobs were professionally self-certified in FY2024 — bypassing full plan examination in exchange for possible post-approval audit (NYC Mayor's Management Report, FY2024).
DOB completed over 92,000 resubmission reviews in FY2024, reflecting how routinely first submissions draw objections that trigger another cycle (NYC Mayor's Management Report, FY2024).
Most delay accumulates before technical review
The data points to the same lever everywhere: most delay accumulates before technical review, in completeness and resubmittal cycles. Permittable's Permit Review Diagnostic checks your plans against applicable codes and common reviewer issues before you submit — so your package is more likely to clear on the first pass.
New York City permitting: FAQ
How long does it take to get a residential building permit approved in NYC?
For jobs filed in DOB NOW, the average time from filing to approval was 20.2 days in FY2024, up 11% from the prior year (NYC Mayor's Management Report, FY2024). That average spans simple alterations to new buildings, and most of the clock is applicant time spent correcting plans, not DOB review time.
Why do permits take longer than the official review time suggests?
DOB's first plan review for a new building averages only about 6.5 days of examiner time (NYC Mayor's Management Report, FY2024). The gap to the ~20-day total is driven by objection-and-resubmission cycles — DOB completed over 92,000 resubmission reviews in FY2024 — because applicants must revise and refile after examiners raise objections.
What is self-certification and how common is it?
Professional Certification lets a licensed architect or engineer certify that plans comply with code, skipping full DOB plan examination in exchange for possible audit (NYC DOB). It is heavily used — over 107,000 jobs were professionally certified in FY2024 — though large new buildings and changes of occupancy are generally not eligible.
Are NYC permit timelines getting better or worse?
They are trending slightly worse: filing-to-approval rose from 18.1 days (FY2023) to 20.2 days (FY2024), and DOB's preliminary FY2025 reporting showed it slipping further alongside higher resubmission volumes (NYC Mayor's Management Report, FY2024–FY2025).

All DOB timeline figures are city-fiscal-year averages from the Mayor's Management Report (July–June) and cover all job types filed in DOB NOW combined, so a specific multifamily new building can take substantially longer than the headline averages; “days to first plan review” measures only DOB examiner time. No official DOB figure for multi-agency high-rise review duration was available, so it is omitted; the ~53,000-units figure is private-sector context, not a DOB metric.
