building blueprints search

Categories: Plumbing

Hi
I am looking for blueprints that outline the layout of my coop building, specifically the layout of the water heat, and waste pipelines.
Is that a DOB possibility? The building dates from the early 1930s. Management company does not have any. Any leads about where I would go to find out?
Thanks.
