Building Codes in New York

Building permit requirements in New York are enforced at the local level, each city and county building department sets its own rules, fees, and timelines. Most cities in New York follow the 2024 IRC, though 4 cities are still on the 2020 edition.

We cover 33 cities in New York with 3,308 specific permit rules. That's real, locally researched data, not generic advice. Each city page shows exactly what triggers a permit, what's exempt, estimated fees, and how to apply.

The bottom line: don't assume your city follows the same rules as the one next door. A fence that's exempt in one town might need a full permit two miles away. Always check your specific city.

Contractor Licensing in New York

If you're hiring a contractor in New York, make sure they're properly licensed. You can verify credentials through the New York DOS – Home Improvement.

Two rules of thumb: never pay a contractor in full upfront, a third down is standard. And if a contractor tells you "we don't need a permit for this," that's a red flag. Use PermitMint to verify before you sign anything.
