Code: LNO (DOB document confirming legal use)
Description: (Letter Of No Objection) is a DOB document that confirms the current legal use of a building or space when no Certificate of Occupancy exists for that property, often in older buildings built or converted before 1938. It does not approve new work or close a permit; it only states that DOB has no objection to the existing use described in the request based on available records.
Practical Meaning: For a NYC homeowner, you may need an LNO when a buyer, bank, or city agency asks for proof that your building’s current use is legal, especially for older pre‑1938 homes or mixed‑use buildings that have no modern Certificate of Occupancy. It does not fix violations or change your legal use; it only confirms what DOB records show about the existing use of space.
Where You May See It: You may see “LNO” in emails or letters from a mortgage lender, title company, or real estate attorney during the sale or refinancing of an older property, or from a city agency that needs to confirm legal use before issuing another permit or license; you can apply for it through the DOB NOW: Build portal or at a DOB Borough Office.
Why It Matters: Without this letter, a sale or refinancing of an older building can stall because lenders and title companies need written proof from DOB that the current use is legally recognized. If DOB records show illegal use or a conflict, this letter may not be issued and you may need additional legal or permitting steps before you can close a transaction.
