Code: PW1C (DOB heating and fuel equipment schedule form)
Description: (Schedule C – Heating and Combustion Equipment) is a DOB schedule attached to the main PW1 form that gives detailed information about boilers, burners, fuel tanks and other heating or combustion equipment in a project. This is filled out by a licensed professional to show fuel type, equipment size and fuel storage details so DOB can review fire safety and code compliance.
Practical Meaning: For a homeowner, this means that if your project adds or replaces a boiler, furnace, burner or fuel storage (for example, an oil tank), your design professional will usually need to file PW1C together with PW1 so the city can approve the heating system.
Where You May See It: You may see PW1C mentioned on DOB job documents, in DOB NOW: Build uploads, in city rule sections that list “PW‑1 with PW‑1C” as required documentation, and in emails or requests from your architect, engineer or boiler contractor.
Why It Matters: PW1C helps DOB and fire‑safety officials check that your heating and fuel systems are installed safely, with the right fuel type, tank size and venting, reducing the risk of fires, explosions or carbon monoxide problems. If this information is not filed or is wrong, you can face serious delays, extra costs to fix non‑compliant equipment, and possible enforcement if unsafe systems are found in your building.
