Why get a Building Permit?

Building permits are required before you build, demolish, repair or alter most buildings, decks, mezzanines, retaining walls, garages, carports, secondary suites, swimming pools, plumbing, sprinklers, furnaces or structures in the City of Port Coquitlam.

It is important to get a Building Permit before starting your project, to:

  • Protect the safety of occupants,
  • Ensure you won’t have to tear your work down and start over with the required permits,
  • Avoid additional permits and fees incurred if you build without a permit,
  • Reassure buyers who avoid purchasing buildings with unauthorized construction,
  • Maintain the value of your home, and
  • Ensure any new buildings and structures comply with all building regulations including the Building and Plumbing Bylaw, the BC Building Code and Zoning Bylaw regulations.
