Unpermitted Work
Unpermitted work means any changes to a home or building that were done without getting the required permit from the NYC Department of Buildings (DOB). This includes many common projects, such as renovations, additions, or system upgrades.
Why It Matters
Unpermitted work can create safety risks, such as faulty wiring that may cause fires, or structural changes that weaken the building. It can also cause problems when you try to sell or refinance the property, because lenders, buyers, or their attorneys may require proof that work was done with permits.
Unpermitted work might seem fine at first, but it can lead to safety risks, like faulty wiring causing fires, or structural issues that endanger your family. The DOB can issue violations, stop-work orders, or fines—starting at $600 for one- or two-family homes, up to $10,000 or more depending on the job.
Common Examples of unpermitted work
How to check and fix unpermitted work
- Check your property’s DOB records online using BIS or DOB NOW, or call 311 for help.
- If you find unpermitted work, speak with a licensed design professional or contractor about filing for a retroactive permit.
- Be prepared to pay civil penalties and inspection fees and to correct any unsafe conditions found by DOB.
