The reason it counts
In Ontario, the Building Code Act and the Ontario Building Code govern plumbing work in houses, and municipalities issue the permits and carry out inspections. In Newmarket that is the Town's building services department. A permit means an inspector checks drains, vents and supply lines before they are covered, which catches mistakes while they are still easy to fix.
Unpermitted work can cause trouble later. Insurers may question a claim involving work that was never inspected, and buyers' lawyers and home inspectors increasingly ask about permits during a sale. Correcting work after walls are finished is far more disruptive than having it inspected at the right time.
Jobs that typically need a permit
- Adding a new bathroom, kitchen or laundry with new drains.
- Relocating fixtures, or changing how drains and vents run.
- Fitting a backwater valve to the main drain.
- Replacing the water service or building sewer.
- Major repiping of supply or drain systems.
Jobs that often do not
- Replacing a faucet, toilet or sink in the same spot with the same connections.
- Clearing a blocked drain.
- Repairing a leak on existing pipe.
- Swapping a water heater for a similar unit, though gas and venting rules still apply and a licensed gas fitter may be required.
Bench note
Always confirm with the town. This is general guidance only. Rules, forms and fees change, and the Town of Newmarket's building department is the authority on what your particular project requires. Neighbouring municipalities such as Aurora and East Gwillimbury have their own departments.
Steps, in order
- Describe the project clearly. Note which fixtures are being added, moved or replaced.
- Contact building services. Ask whether a permit is needed and what drawings they expect.
- Prepare drawings. Simple projects may need only a floor plan and plumbing layout; larger work may need more.
- Book inspections at the right stages. Typically there is an inspection of underground or rough-in piping before it is covered, and a final inspection.
- Keep the records. File the permit and inspection results with your house documents for insurers and future buyers.
Who pulls the permit
Homeowners can often apply themselves, though many hire the contractor to do it. Either way, make sure someone takes responsibility, and that the person doing the work is properly qualified. For a sense of how a basement project unfolds, read our circular on renovation plumbing planning. Kitchen projects bring their own drain concerns, discussed in grease and kitchen drains.

Phoned-in questions
Can I do my own plumbing with a permit in Newmarket?
Homeowners can often do work on their own house with a permit, subject to the town's requirements. Ask building services before starting.
Does swapping a toilet require a permit?
Swapping one toilet for another on the same flange generally needs none, but moving it or altering the drain typically does.
