Code: NBBE (New building with existing elements)
Description: NBBE (New Building with existing elements to remain) is a DOB job type label used when a project is filed as a new building but some parts of the existing structure will remain. It sits under the broader New Building (NB) job family and follows similar rules, but it flags that the filing includes existing elements instead of a completely empty site.
Practical Meaning: If your project is classified as NBBE, DOB is treating it as a new building filing even though some existing structural or building elements will stay in place. For a homeowner, this means you may have new‑building‑level review and requirements while also dealing with the risks and constraints of tying new work into an existing structure.
Where You May See It: You may see NBBE in DOB NOW job‑type tables, on filing summaries from your architect or expediter, and in DOB documentation that compares BIS job types to DOB NOW: Build job types. It can also appear in internal project spreadsheets and reports that break out NB jobs where existing elements remain.
Why It Matters: NBBE projects can be more complex than a simple NB or a straight alteration, because they must satisfy both new‑construction rules and all safety and structural requirements for the existing pieces that remain. Misunderstanding this category or filing under the wrong job type can lead to redesigns, extra reviews, and delays before DOB will issue permits or a Certificate of Occupancy.
