When you need a Window & Door permit in Dayton
Like-for-like window and door replacement (same rough opening) is commonly exempt from a building permit when the U-factor meets local energy code. Resizing the opening, adding new openings, or replacing egress windows in sleeping rooms (IRC R310) requires a permit. Many jurisdictions still require permits for like-for-like when the windows are impact-rated (coastal zones).
