Do You Need a Permit? A Plain-English Guide for Etobicoke Renovations

The question we get on almost every first call: "Do we really need a permit for this?" The honest answer is sometimes yes, sometimes no, and the line is not always where people expect it.

Etobicoke is part of the City of Toronto, so it is Toronto Building that issues permits here, under the Ontario Building Code. What follows is a practical guide based on the City's own list, not legal advice. When a job is close to the line, call 311 or ask whoever is quoting it.

Things that generally do not need a building permit: painting, new flooring, replacing kitchen cabinets and counters in the same layout, swapping a toilet, sink or tap for a new one in the same spot, re-tiling without moving plumbing, re-shingling a roof, replacing a window or door with one the same size, replacing a furnace, adding insulation, and installing a gas fireplace or a sump pump. Finishing a basement can fall on either side. If there is no new plumbing, no heating changes and nothing structural, it usually does not need one.

Things that generally do need one. Removing or adding walls, or cutting a new opening or making an existing one bigger. Adding or modifying plumbing, like a new bathroom, moving a toilet, adding a laundry room or roughing in a basement shower. Changing the heating system, such as new ductwork runs. Any addition, including a second storey, a sunroom or a porch. Underpinning or lowering a basement. A deck more than 60 cm off the ground. A secondary suite, even if almost no construction is involved. A wood-burning fireplace or a new chimney. And yes, installing a backwater valve needs a plumbing permit.

Electrical is separate. Electrical work in Ontario goes through the Electrical Safety Authority, not the City, and it should be done by a licensed electrical contractor who files the notification. That applies even to a job that needs no building permit at all, like adding circuits in a kitchen refresh.

Zoning is a different question again. A building permit checks that the work is built safely. Zoning decides whether it is allowed at all: how close to the lot line, how tall, how much of the lot it covers. If an addition or a deck does not fit the zoning bylaw, you need a minor variance from the Committee of Adjustment before a permit can be issued. That process takes months, not weeks, so find out early.

How long does a permit take? For a house, the Building Code sets a ten-business-day review target once the application is complete. The key word is complete. Missing drawings, a missing structural engineer's stamp or an unclear site plan stops the clock, and that is where most delays come from.

Who should pull it? Either the homeowner or the contractor acting as agent can apply. We usually handle it, because we are going to be the ones meeting the inspector. Be wary of anyone who suggests skipping it to save time or money, or who asks you to apply in your name for work they are doing. If something goes wrong, the permit is in your name.

What actually happens if you skip it? Sometimes nothing, for a while. Then a neighbour complains, or an inspector notices a dumpster, and you get an order to stop work. You may have to open finished walls so the framing, plumbing and insulation can be inspected. And unpermitted work tends to surface at the worst time: when you sell, when the buyer's home inspector flags it, or when you make an insurance claim and the adjuster asks about the basement apartment.

Our take is simple. If the work changes the structure, the plumbing layout, or what the space is used for, assume it needs a permit until someone tells you otherwise. The permit fee is a small fraction of most renovation budgets, and the inspections are a free second opinion on the work.
