NYC sign permit at a glance
| Question | Short answer |
|---|---|
| Do I need a permit? | Yes for sign displays and installations (Construction Code §28-105.1), except painted signs or signs smaller than six square feet and not illuminated (when you need one). Other cities compared. |
| What sets my limit? | Your zoning district, and whether the sign is lit: in C1 and C2 a non-illuminated sign may be three times the street frontage up to 150 sq ft, but only up to 50 sq ft when illuminated (allowance by district). Other cities compared. |
| Which permits? | A Sign (SG) permit through DOB NOW: Build, an Alteration (ALT) permit if the sign is attached to a structure, and a separate electrical permit by a licensed electrician (application steps). |
| Who installs? | A licensed Sign Hanger, except for signs under 75 sq ft, ground-supported signs, directional signs and temporary construction signs (installer). Other cities compared. |
| What does it cost? | The building alteration filing fee plus a charge by sign area and type; a wall sign adds $5 for each 100 sq ft, not less than $35, and an illuminated sign carries an annual use fee (fee table). |
| How long does it take? | DOB does not publish a review or processing time for sign permits. Other cities compared. |
| Sidewalk A-frame sign? | The city’s 311 guidance says a sandwich or A-frame sign must not extend more than 3 feet into the sidewalk from the building or be higher than 5 feet (NYC311). Other cities compared. |
| Window signs? | In commercial districts, lit non-flashing window signs other than advertising signs, up to eight square feet in total on the zoning lot and no more than three in any window, are exempt from the sign surface-area limit (ZR §32-64). Other cities compared. |
| Historic district? | A sign that affects the exterior of an individual landmark or a building in a historic district needs a Landmarks Preservation Commission permit, filed through Portico, even if the work needs no Department of Buildings permit (LPC permit types). Other cities compared. |

Why NYC signs get flagged
New York City does not set one sign rule for the whole city. The NYC Zoning Resolution ties your maximum legal sign area to the zoning district your building sits in, and then cuts that allowance sharply the moment your sign is illuminated. A 50-foot-wide storefront in a C1 district can run a 150 sq ft non-illuminated sign — but light it up and the cap collapses to 50 sq ft. Owners who size a bright sign off the non-illuminated number are the ones who get the violation notice.
The Department of Buildings requires a permit for sign displays and installations (Construction Code §28-105.1), except painted signs or signs smaller than six square feet and not illuminated. This tool reads the same zoning rules the city enforces and tells you where your plan stands before you commit to fabrication.
NYC commercial sign allowance by district
Maximum accessory sign area. "Mult" = multiply by your street frontage in feet; the cap is the hard ceiling.
| District | Non-illuminated | Illuminated | Flashing/LED |
|---|---|---|---|
| C1 / C2 | ×3, max 150 | ×3, max 50 | Not allowed |
| C3 | 50 max | Not allowed | Not allowed |
| C4 / C5-4 / C6 / C7 | ×5, max 500 | ×5, max 500 | ×5, max 500 |
| C5-1/2/3/5 | ×3, max 200 | Not listed in §32-643 to §32-645 | Not allowed |
| C6-1A | ×5, max 500 | ×5, max 500 | Not allowed |
| C6-5 / C6-7 | No size limit | No size limit | No size limit |
| C8 | ×6 total, max 750 per sign | ×5 total, max 500 per sign (§32-645) | ×5 total, max 500 per sign (§32-645) |

How to apply for a New York City sign permit — 5 steps
In New York the illumination decision comes before the size decision, because lighting the sign changes the number you are allowed.

Sources & how this page is maintained
Sources and official references: NYC Department of Buildings — Sign Permit Requirements · NYC Zoning Resolution §32-642 — Permitted Surface Area of Signs · §32-643 · §32-644 · §32-645 · §32-652 · §32-655. Measured on 21 August 2026: §32-642 extracts as text and carries every surface-area figure quoted on this page. Correction, 8 September 2026. This page previously said a non-illuminated sign of 6 sq ft or less needs no DOB permit. That threshold is not in the Zoning Resolution sections registered as this page's source: §32-642 through §32-645 were collected in full on 8 September 2026 and contain no six-square-foot figure and no DOB permit threshold. The claim has been removed rather than re-sourced — the permit question belongs to the Building Code, which this page does not cover and has not collected. Height, §32-655 (last amended 12/5/2024). Read from the ordinance on 15 September 2026: no permitted sign may extend above curb level higher than 25 ft in C1, C2, C3, C5-1, C5-2, C5-3 and C5-5; 40 ft in C4, C5-4, C6-1, C6-2, C6-3, C6-4, C6-6, C6-8, C6-9, C6-11, C6-12 and C7; and there is no restriction as to height in C6-5 and C6-7. The section carries no illumination-based exception. The 40 ft ceiling with a 58 ft allowance for non-illuminated or indirectly illuminated signs belongs to C8 alone, under §32-654 (last amended 12/15/1961). This page previously carried the C8 pair as a citywide rule; that is corrected. New source, 29 September 2026. The NYC Department of Buildings “Sign Permit Requirements” page is now registered as a source and read; the reading is stored verbatim. It carries the Construction Code §28-105.1 permit requirement, the SG / ALT / electrical filing routes, the §28-415.1 licensed Sign Hanger requirement with its exemptions, and the annual permit for illuminated signs projecting beyond the building line — all set out in the four sections above. It also carries the permit exemption for signs that are painted or smaller than six square feet and not illuminated, which this page removed on 8 September 2026 for want of a source: it is stated again above, cited to this DOB page rather than to the Zoning Resolution. That page states no permit fee amount and no review or processing time, so the new sections give neither.
How much does an NYC sign permit cost?
New York charges the building alteration filing fee for your job, then adds a per-area charge on top of it by sign type. The add-ons and the minimums are set out in the Administrative Code. We do not print the alteration filing fee itself here because we could not confirm it line by line.
The part that catches people is further down the table. An illuminated sign carries an annual use fee, every year, for as long as the sign is lit.
| Sign type | Added to the filing fee | Renewal |
|---|---|---|
| Ground sign, wall sign, or any sign mounted to a wall or other structure | $5 for each 100 sq ft of surface area, or fraction thereof, not less than $35 | $130 |
| Roof sign with a tight, closed or solid surface | $15 for each 100 sq ft of surface area, or fraction thereof, not less than $70 | $130 |
| Roof sign without a solid surface, not more than 31 ft above roof level | $15 for each 100 sq ft of surface area, or fraction thereof, not less than $130 | $130 |
| Roof sign without a solid surface, over 31 ft above roof level | $25 for each 100 sq ft of area, or fraction thereof, not less than $135 | $130 |
The last row read the same on two of our three readings of the code page, so treat it as the code states it and check the table yourself before you file.
| Illuminated sign, one side | Annual use fee |
|---|---|
| 30 sq ft or less | $45 |
| More than 30 and not more than 50 sq ft | $70 |
| More than 50 sq ft | $0.75 per sq ft or part thereof, annually, not less than $130 |
This is charged every year the sign is illuminated, not once.
