What plumbing code applies to bathroom renovations?

Ontario Building Code (OBC) and the Ontario Plumbing Code are the primary regulations governing bathroom renovations in Ottawa, along with local City of Ottawa bylaws and requirements.

The Ontario Plumbing Code specifically covers all plumbing installations, including fixture placement, pipe sizing, venting requirements, and water supply systems. For bathroom renovations, this means proper spacing around toilets (minimum 15 inches from center to any wall), adequate venting for all fixtures, and proper slope requirements for drain lines. The code also mandates specific materials - for example, supply lines must use approved materials like copper or PEX, and all joints must be accessible or properly sealed.

Electrical work in bathrooms falls under the Ontario Electrical Safety Code, which requires GFCI protection for all outlets, proper spacing from water sources, and dedicated circuits for high-draw items like heated floors or exhaust fans. Any electrical work beyond simple fixture replacement requires a licensed electrician and electrical permit.

City of Ottawa requirements add another layer, particularly for permit applications and inspections. Most bathroom renovations involving plumbing changes, electrical work, or structural modifications require building permits. New basement bathrooms always require both plumbing and building permits, as they involve new rough-in work and potential structural considerations for drainage.

Licensed contractors like Ottawa Bathrooms handle all permit applications and ensure work meets code requirements. We coordinate inspections at required stages - typically rough-in inspection before covering walls, and final inspection before occupancy. This protects homeowners from costly mistakes and ensures proper insurance coverage.
