Code: Wall (Interior or exterior building part)
Description: (Wall) is a vertical building part that encloses a space, separates rooms, or supports parts of a building. It may be an exterior wall, an interior partition, or a temporary wall intended for later removal.
Practical Meaning: Before adding, removing, or changing a wall, ask a registered architect or professional engineer whether the work needs DOB approval and permits. Calling a wall “temporary,” “removable,” or “pressurized” does not automatically make it exempt from permit requirements.
Where You May See It: On floor plans, renovation drawings, contractor proposals, DOB permit applications, inspection reports, or apartment listings that advertise a “flex” layout. DOB uses “flex” to describe an apartment layout that may be divided using pressurized walls.
Why It Matters: Wall changes can affect safe access to exits and whether an apartment layout is legal. Installing a temporary or permanent wall without required permits can lead to DOB enforcement; a removable wall does not automatically create a legal bedroom or apartment.
