Code: PW1B (DOB plumbing and sprinkler schedule form)
Description: (Schedule B – Plumbing, Sprinkler, Standpipe) is a DOB schedule attached to the main PW1 form that gives detailed information about plumbing, sprinkler and standpipe work in a project. This is filled out by a licensed professional to show the exact systems, fixtures and piping that will be installed, changed or removed.
Practical Meaning: For a homeowner, this means that if your project includes plumbing changes, new bathrooms or kitchens, sprinkler work or standpipe piping, your design professional will usually need to file PW1B together with the PW1. If PW1B is missing, incomplete or wrong, DOB can delay approval of your job or ask for corrections before you can get permits.
Where You May See It: You may see PW1B listed on DOB job records, in the documents uploaded in DOB NOW: Build, in emails from your architect, engineer or expeditor, and sometimes in a list of required forms for New Building or Alteration jobs that include plumbing or fire‑protection piping.
Why It Matters: PW1B helps DOB check that all plumbing, sprinkler and standpipe work in your building is designed safely and matches NYC code, which can reduce leaks, water damage, and fire‑safety problems. If it is not done correctly, you may face delays, extra design fees, repeat inspections, or violations connected to unapproved or incorrectly described plumbing and fire systems.
