New York permit questions
Do you need a permit for home renovations in New York?
New York enforces a statewide code (New York State Uniform Fire Prevention and Building Code), so permit requirements are broadly consistent across the state, but the permit itself is issued by your city or county. Structural, electrical, plumbing, mechanical and envelope work almost always require one.
Can a homeowner pull their own permit in New York?
Homeowner permits allowed upstate; New York City is far more restrictive. Owner-builder status usually makes you responsible for code compliance and for any unlicensed work performed on the property, and many jurisdictions restrict resale within a year of the permit.
