Many home improvement projects in New York City require permits. Repair projects and major changes, such as structural, electrical, heating, and plumbing work, are projects that will require a permit with certainty. Simple repairs usually don't require a permit, but for major changes, you should check with your local construction department for a permit. Even if you find a cheap New York apartment in affordable New York City neighborhoods, permission for major changes and renovation projects is a must.

You don't need to get a permit, but you must have a licensed home improvement contractor to do so.
