What is different about septic system replacement in New York
New York City operates its own construction codes and DOB filing process; a project that is a one-form permit upstate can require a licensed filing representative in the five boroughs.
Owner-builder: Homeowner permits allowed upstate; New York City is far more restrictive. Septic System Replacement generally requires a licensed contractor to pull the permit, even where owner-builder status is available.
