What renovations require a permit?

What renovations require a permit? I’m considering some home improvements, and I want to know which projects will need official approval.

Permits needed for major changes like additions, plumbing, and electric.

Many renovations need a permit, like structural changes, electrical work, plumbing upgrades, and major additions. Also, roofing, new windows, and fences over a certain height might require one. Always check with your local building department to ensure compliance and avoid fines. Better safe than sorry!
