Set by local rules
Do you need a permit for Window Replacement in Hamilton County?
In New York, there is no single statewide rule for a Window Replacement; whether you need a permit is decided locally in Hamilton County.
New York adopts the 2018 energy code statewide, so replacement windows must meet its U-factor and SHGC; a replaced bedroom window may keep the existing opening if it provides equal or greater escape area (IRC R319). Whether a like-for-like replacement needs a permit is set by your local jurisdiction, and resizing or adding an opening always requires one. Because New York leaves this to local jurisdictions, the reliable answer comes from Hamilton Building Permits. Zoning setbacks apply either way.
