The need for a permit in kitchen remodeling depends on the scope of your project. Generally, minor cosmetic changes like painting, replacing cabinet doors, or updating hardware don't require permits. However, major renovations typically do need permits. These include changing the kitchen layout, moving or adding electrical outlets, altering plumbing lines, removing or adding walls, replacing windows or exterior doors, and installing new gas appliances. Permit requirements vary by location, so it's best to check with your local building department. When in doubt, consult a licensed contractor who can guide you through the permit process and help determine if your specific renovation requires official approval.
