Is a City of Ottawa permit needed for an interior drain system?

The sump pit and pump in an interior system are protective plumbing devices, and the City of Ottawa says a building permit is required to install them, before the work starts. Whether the drain channel itself counts as "drain tile replacement" on the City's permit list is not stated, so ask the City about that part.

The drain channel connects to a sump pit and the pump discharges somewhere, so there is a plumbing component: ask whether a licensed plumber does or signs off that part.

The sump pit and pump may also qualify for the City's protective plumbing rebate; check ottawa.ca for the current terms, since the City lists the program as under review. The permit fee for plumbing work only is $117 per application under the City's 2026 fee schedule.

A fair quote for this work should set out in writing:

• the length of drain channel being installed and where it runs
• whether existing drain tile is being replaced or left in place, and where the system drains
• the sump pit dimensions (Ontario's Building Code requires at least 750 mm deep and 0.25 m² in area, with a cover that resists removal by children and is airtight)
• whether the pump includes battery backup, and the make and model
• who applies for the building permit and pays the fee

Make sure the written contract names who is responsible for pulling the City permit, because the permit must be in hand before work begins and the City requires an inspection when the work is complete.
