Hi everyone. I am planning to install new railings going up my stoop steps. My iron guy tells me the posts — the vertical “spindles” perpendicular to the handrail — need to be 4 inches apart. But others tell me that that code doesn’t apply to single family homes. It’s a Landmarked house but the Landmarks Preservation Commission doesn’t know the answer either. I’ve tried to download the DOB code and I am baffled. Can anyone please offer any advice?

  1. It’s called the 4″ ball test. Best to make the spacing e.g., 3 3/4″ apart. Rationale is to prevent a small child from getting his or her head caught.

  2. I am in the process of obtaining LPC permits. We’ve been going back and forth on proposed designs. But they only care about what is historically accurate, not what is up to code. I want to have their approval AND be up to code.
    Thanks.
