1. Why Does NYC Care About Permits?
The Department of Buildings (DOB home page) keeps families safe by checking plans before walls move. No permit can lead to:
- Stop-work orders—workers down tools on the spot.
- Fines—often $6 000 + per offense.
- Insurance claims denied—carriers may refuse payouts.
Story time: The silent ceiling crack
Mark in Bay Ridge removed a load-bearing wall without a permit. A month later a hairline crack stretched across the ceiling. One rainy night the crack popped—water rushed in from an unsealed roof beam. Repairs plus fines cost $22 000. Mark now calls permits “cheap insurance.”

Oops: Missed inspection in Astoria
Rico’s electrician finished rewiring but never booked the final inspection. Six months later a buyer’s lender found the open permit. The sale paused for three weeks while Rico rushed the sign-off. Lesson: always close the loop.
