How long does an NYC building permit take to issue?

A realistic timeline for general contractors and owners working in New York City · Updated April 2026

The short answer: between two weeks and two years, depending on the job. A standard alteration permit on a small commercial space typically issues in three to six weeks. A new ground-up building can sit in plan examination for six months or more. A landmark or zoning variance pushes that further. And these numbers assume nothing goes wrong — most NYC permits go through at least one round of objections, which adds two to four weeks each.

If you're a contractor watching for the right moment to bid, or an owner trying to schedule a project, knowing the realistic timeline matters more than knowing the average. Averages hide the cases where you can move early and the cases where you should expect to wait.

The timeline by job type

Permit Pipeline tracks every new filing in NYC's Department of Buildings system. From DOB NOW Build job filings (Socrata dataset w9ak-ipjd) and the related permit issuance feed (rbx6-tga4), the typical durations look like this:

These are observed medians from the past year of filings. The mean is much higher because of long-tail outliers — projects that get stuck in litigation, environmental review, or design change. If you're underwriting a schedule, plan from the median and budget contingency for the long tail.

What's actually happening between filing and issuance

The clock has four stages. Each stage has its own typical wait.

1. Initial intake (1–3 business days). The filing is logged, fees calculated, and assigned to a plan examiner queue. This is fast — usually within a week.
2. Plan examination (1–8 weeks). A DOB plan examiner reviews the drawings against the building code. They issue objections in writing. Almost no first submission passes clean.
3. Objection response (1–4 weeks per round). The applicant — usually the architect or expediter — responds to objections. The reviewer comes back with another round. This can repeat two or three times on a complex job.
4. Permit issuance (3–10 business days after final approval). Once all objections clear, the permit issues automatically as long as fees are paid and required signoffs (FDNY, DEP, Landmarks if applicable) are in.

Plan examination — the leg that varies most

Plan examination is the single biggest source of variance. A simple alteration in a building with no special characteristics might pass in two weeks. The same scope of work in a landmark district, an SRO, a hospital, or a scaffold-permit-heavy block can sit for two months waiting for a senior examiner to weigh in.

What slows plan exam:

• Building has prior open violations. DOB will not issue a new permit until the open violations are resolved or the new work specifically corrects them.
• Landmark Preservation Commission (LPC) referral. Anything in a designated district or on an individually landmarked building has to clear LPC first. This adds 4–12 weeks before DOB even starts the building-code review.
• Zoning Resolution interpretation needed. If the project requires a zoning interpretation (ZRD-1) or a Board of Standards and Appeals variance (BSA), expect months, not weeks.
• Use Group 9 or higher (assembly, healthcare, dorms, hotels). These trigger additional review by the FDNY Bureau of Fire Prevention and sometimes by the Department of Health.
• Site is in the 100-year floodplain. Triggers DOB Flood Resistant Construction review.

What's already happening before the permit issues

This is the part most contractors miss: by the time the filing is in the public record, the owner has often already started planning. The architect is usually engaged. The general contractor may be on the short list. The MEP subs are sometimes already in conversations.

The implication: the public filing is your last chance to introduce yourself. Wait until permit issuance and the bid list is closed. Reach out at filing and you have a real shot — especially on jobs where the owner doesn't have a long-standing GC relationship.

Using timing data to bid smarter

Once you know the typical wait by job type, you can be strategic about which filings to chase first. Three quick rules:

• Alteration Type 1 filings are your sweet spot. Long enough wait (4–10 weeks) that you have time to reach the owner. Short enough that the project is real and likely to break ground.
• New Building filings need patience. A new-building filing might be 6–9 months from groundbreaking. Build the relationship now, but don't expect a quick close. Earlier is better — see why.
• Skip Alteration Type 2. The wait is so short and the scope so small that by the time you reach the owner, the work is often done. The exception: AT2 filings on commercial spaces that signal a tenant move-in — those can be GC opportunities of a different kind.

A practical timeline a contractor can use

Here's how a realistic NYC alteration job actually unfolds, with the dates you can reach the owner at each step:

1. Day 0: Owner files job application. Filing appears in DOB NOW within 24 hours.
2. Days 0–14: Plan examiner queue. Owner is finalizing scope, often still picking GC.
3. Days 14–28: First round of objections. Architect responds. This is the warmest window for outreach.
4. Days 28–56: Objection response and re-review. GC is usually being chosen or already chosen.
5. Day 56–70: Permit issued. Work can begin. Bid list closed.

If you reach out in the days 14–28 window with a credible specific message, you're often the only contractor the owner has heard from. By day 56, you're competing with five others.

Why most contractors are too late

Most GCs check DOB after permits issue — that's the data that's easy to find and easy to filter. By then the bid list is set. The contractors who consistently win mid-market NYC work are the ones who've built a habit around the filing-to-issuance window. They're not waiting for the project to be advertised. They're treating the filing itself as the lead.

That's the workflow Permit Pipeline is built around. Filings are scored, deduped, and emailed out the morning after they hit the public record — so your first chance to reach the owner doesn't disappear into a 100-row CSV. See what today's filings look like in our feed.
