Code: BDM (Boiler code variant)
Description: (Boiler Violation Code – BDM Variant) is a DOB internal boiler code label that appears in some violation lists as a re-ordered form of the BMD boiler code. It refers to the same boiler violation category as BMD and does not change the meaning, penalty, or type of problem noted on the violation.
Practical Meaning: For a homeowner, seeing BDM instead of BMD on a DOB document still means there is a boiler-related violation and you must treat it as a boiler problem that needs correction and, if required, a hearing. You should focus on the actual violation description and boiler condition, not on the letter order inside the boiler code.
Where You May See It: DOB violation code lists, PDF summaries of DOB violation codes, internal or historic BIS reports, data exports or audit tools that reproduce the city’s boiler code table.
Why It Matters: Understanding that BDM and BMD both mean “Boiler” helps you avoid confusion when you compare different DOB records, spreadsheets, or open-data tables and see both labels used for the same boiler code category. This reduces the risk of thinking you have multiple different violations when in fact they are the same boiler violation family and should be handled together with your boiler contractor and any required DOB filings.
