Plumbing Permits in Aurora

Jobs that need permits

Under the Ontario Building Code, many plumbing projects need a building permit. The exact list depends on the scope, and the Town of Aurora building division has the final say. As a general guide, permits are typically needed when you:

• Add new fixtures, such as a bathroom in the basement.
• Relocate or extend drains, waste and vent piping.
• Install a backwater valve.
• Replace large portions of the drainage or water distribution system.
• Make changes connected to a renovation that also needs a building permit.

Like-for-like repairs, such as replacing a faucet, a toilet in the same spot, or fixing a leak on existing piping, usually do not need a permit. When in doubt, ask before starting.

Inspections

Once a permit is issued, the work is inspected at set stages. For plumbing, that usually means:

1. Underground or rough-in inspection before pipes are covered by concrete, insulation or drywall. Drains may be tested with water or air to show they hold.
2. Final inspection after fixtures are connected and working.

Someone must book each inspection and be available to give access. Do not close up walls or pour concrete before the rough-in passes. An inspector who cannot see the pipes may ask for them to be exposed.

Selling your home

Unpermitted work can surface at sale time. Buyers' inspectors and lawyers increasingly ask about permits for basement apartments, added bathrooms and major renovations. An open permit that never received final inspection can also come up in a title search. Missing permits do not automatically sink a sale, but they can delay it, lead to price negotiations, or create insurance questions.

Keep permit documents, inspection reports and contractor invoices together with your house records. If you are buying, ask the seller for them; see checks before buying an older home.

Checking with the Town

Before booking a project, gather a short description of the work, a simple drawing showing fixtures and drain routes, and your property address. The building division can tell you whether a permit is required, which drawings are needed, and roughly how long review takes. Fees and processing times change, so get current figures directly.

Licensed plumbers in Ontario work under provincial trade rules, and a contractor who suggests skipping a required permit is a red flag. Our guide to choosing a plumber has more questions to ask.
