Do New York jurisdictions agree?
Every row below is a measurement at least two New York jurisdictions publish, compared against each other. This is the question a statewide answer cannot settle, because the number that governs your project is the one your own city or county publishes.
| Project | Published threshold | Jurisdictions | Agreement |
|---|---|---|---|
| Fence | 2 to 6 feet | 3 | 3 different numbers |
| Deck | 8 to 18 inches | 2 | 2 different numbers |
| Shed | 120 to 144 sq ft | 4 | 2 different numbers |
| Pool | 24 inches | 2 | Same number in all 2 |
1 of 4 comparable measurements are uniform across New York; 3 are not. Latest verification 2026-08-15.

Building without a permit in New York
New York runs two entirely separate systems and the dividing line is the New York City boundary. Outside New York City the state Uniform Fire Prevention and Building Code applies and Executive Law 382(2) is the penalty provision: a person served with an order to remedy who fails to comply within the time fixed, and any owner, builder, architect, tenant, contractor, subcontractor or construction superintendent who knowingly violates the uniform code or a lawful order made under it, is punishable by a fine of not more than $1,000 per day of violation, or imprisonment not exceeding one year, or both, for the first 180 days.
