What Is the Difference Between NYC DOB And NYC DEP?

NYC DOB is the Department of Buildings.


NYC DEP is the Department of Environmental Protection.


For backflow-prevention devices, the NYC DEP drawings have an entirely different set of requirements from the drawings filed with the NYC DOB.  The DOB drawings merely indicate location of the device but do not provide the specific components, selections, sizes, and access requirements from the DEP.
