Code: LOC – Letter Of Completion (official status)
Description: Letter Of Completion (LOC) is a DOB document that officially closes a permitted construction or alteration project when no new or amended Certificate Of Occupancy is required. DOB issues it after all required sign‑offs, inspections, and final filings are accepted in the system.
Practical Meaning: For a NYC homeowner, this is the final document that tells you and DOB that your permitted project is legally closed and the work is accepted, without changing the building's official use or occupancy. You need all required inspections passed, all outstanding violations or stop‑work orders resolved, and all professional sign‑offs submitted before DOB will issue this letter, so make sure your contractor and filing representative track these steps carefully.
Where You May See It: You will see this document referenced in DOB NOW: Build when checking the status of your job application, on the DOB permit status page for your property, and in closeout instructions from your architect, engineer, or expediter. It also appears in DOB guides about when a CO is required versus when an LOC is enough, and in real estate due diligence reports that check whether all open permits on a property are properly closed.
Why It Matters: A missing, incorrect, or outdated CO is one of the most common and most serious compliance problems for NYC building owners, affecting the ability to rent units legally, collect rent, get financing, or sell the property. Understanding the difference between a CO, an LOC, and a Letter Of No Objection helps you know exactly what document you need in each situation and avoid giving the wrong paperwork to lawyers, banks, or city agencies.
