Code: Letter of No Objection (DOB confirmation letter)
Description: (Letter of No Objection) is an official DOB letter that confirms the legal use of a building when there is no Certificate of Occupancy, usually because the building was constructed before 1938.
Practical Meaning: For a NYC owner of a pre‑1938 building without a Certificate of Occupancy, this letter is the main document that shows banks, buyers, or other agencies that DOB accepts the existing or proposed use as legal.
Where You May See It: You may see this term on NYC 311, DOB information pages, real estate closing checklists, lender or title company document requests, and in emails from your architect, expediter, or attorney when they ask you to visit the local DOB Borough Office.
Why It Matters: Field 10 — Why It Matters: Without this letter, it can be hard to prove that the current use of a pre‑1938 building is legal, which can delay refinancing, sales, new leases, or other approvals.
