Whether you’re planning a remodel or repairing a leaky pipe, understanding Tacoma plumbing codes is essential. These regulations are designed to protect your home, your health, and your wallet—but if you’re not a licensed professional, it’s easy to make mistakes that can cost you big.

  • Washington State Plumbing Code (WSPC) – Based on the 2018 Uniform Plumbing Code (UPC)
  • City of Tacoma Building and Development Codes – Includes local amendments and permit procedures
