Permit activity in New York City
Igni counted 94,969 permits issued in New York City over the last 12 months (Oct 2025 – Sep 2026) — roughly flat (−0.3%) on the 95,246 in the 12 months before. The forecast expects about 44,382 over the next 6 months.
The source's volume stepped up around September 2021 (×1.5) — likely a change in what the city publishes, so we don't compare year over year across it.
Forecast: seasonal naive, typical error ±6% in backtests one to six months ahead. How we forecast
| Permit type | Last 12 months | Year over year | Forecast, next 6 months |
|---|---|---|---|
| All permits | 94,969 | Flat (−0.3%) | ≈ 44,382 |
| Residential building | 6,304 | Up 10.1% | ≈ 3,141 |
| Commercial building | 3,507 | Up 10.1% | ≈ 1,723 |
| Trade (electrical, plumbing, mechanical) | 57,840 | Down 4.8% | ≈ 26,093 |
| ADU | 147 | —* | — |
* No year-over-year figure: the source's volume for this permit type stepped up within the last two years — likely a change in what the city publishes — so the two 12-month windows are not comparable.

Counts are permits issued per calendar month as New York City publishes them to its open-data feed — not a complete census; a change in what the city publishes moves them too. The current month is left out, and the most recent months are provisional. A forecast is a statistical estimate with a range, not a prediction for any project. Informational only.
How long do permits take in New York City?
Based on 247,551 New York City permits applied for between Nov 2023 and Aug 2026, the typical (median) permit was issued 10 days after application, and the middle half of permits took 2–50 days. One in ten took longer than 156 days.
| Permit type | Median | Typical range | Permits |
|---|---|---|---|
| All permits | 10 days | 2–50 days | 247,551 |
| Residential building | 24 days | 7–78 days | 15,050 |
| Commercial building | 13 days | 5–40 days | 8,848 |
| Trade (electrical, plumbing, mechanical) | 7 days | 1–38 days | 156,857 |
| ADU | 40 days | 15–95 days | 101 |
Typical, not guaranteed: individual permits vary with project scope, application completeness and plan-review workload. Days are calendar days from application to issuance; applications still pending are counted as not-yet-issued rather than dropped. Informational only, not legal advice. How we calculate approval times.
Housing law — New York
Statewide ADU mandates have not passed in New York; the action is in New York City, which legalized ADUs across much of the city and opened basement/ADU filings through DOB NOW.
NYC's 'City of Yes for Housing Opportunity' (adopted December 2024) legalized ADUs, cut parking mandates near transit, and enabled office-to-residential and transit-oriented development.
New York City ADU rules
New York City legalized accessory dwelling units through 'City of Yes for Housing Opportunity,' the citywide zoning overhaul the City Council adopted on December 5, 2024 — the most sweeping change to residential zoning in a generation. The reform allows ADUs (the city also calls them ancillary dwelling units) such as backyard cottages, garage conversions, and basement or attic apartments.
ADUs are permitted only on lots with one- or two-family homes — not rowhouses, townhomes, or attached buildings — and are generally capped at 800 square feet. The property owner must live in either the main home or the ADU. Units are not allowed in historic districts or in the lowest-density contextual zones (R1A, R2A, R3A) unless the lot sits in the Greater Transit Zone. Siting rules require an ADU within 100 feet of the street with a five-foot access path and at least five feet from lot lines; cellar units add egress and sprinkler requirements and are barred in high-flood-risk areas.
Implementation is phased: the Department of Buildings began accepting ADU applications through its DOB NOW: Build portal on September 30, 2025, under Local Laws 126 and 127. A separate path lets some pre-existing basement units — in operation before April 20, 2024, in designated program areas — pursue legalization. New York State has no statewide ADU mandate, so these city rules govern.
This is an informational summary — verify current rules with the city's planning/permitting department; not legal advice.
