Permits for a kitchen countertop swap in Toronto

The City of Toronto publishes a list of work that does not require a building permit. Its two closest entries for a countertop job are installation of cabinetry and millwork, and repairing and replacing plumbing fixtures. A new slab on existing cabinets, with the sink going back into the same opening, fits that reading. Adept Renovation & Painting, a Toronto renovation contractor, lists replacing cabinets and countertops in the same layout as work that does not need a building permit. Josh Kitchen, a GTA kitchen and cabinet company, reports in its countertop guide that in most GTA municipalities, simply replacing countertops does not require a building permit.

The City adds two qualifications. It says the exempt list is not exhaustive and that judgment should be used depending on the situation. It also says compliance with the Zoning Bylaw is required even where a building permit is not. A sink shifted a few centimetres along the same run to suit a new cut-out is named on neither list, so that case is a question for Toronto Building.

The City's list of work that does require a permit includes structural or material alterations and installing or modifying heating or plumbing systems. A drain moved to the middle of a new island changes the plumbing system, so that job needs a permit. Three nearby changes come up on countertop jobs:

• Adding a dishwasher where there was none: Adept's cost guide lists a plumbing permit as required for moving sinks and adding dishwashers.
• Replacing an existing dishwasher: this sits closer to the City's exempt entry for replacing plumbing fixtures.
• Moving a gas cooktop to a new cut-out: this is gas work, and TSSA, Ontario's fuels safety regulator, says only TSSA-registered fuels contractors can legally do fuels-related work in Ontario.

Keeping fixtures in place also has a budget effect. Adept reports that keeping the sink, stove and plumbing where they are saves $5,000 to $15,000 against relocating them. The kitchen renovation cost guide sets out the rest of that budget, and the countertop installation cost guide covers what a swap alone runs.

The examples below are separate cases, not one bill. A sink move with no other alterations can go on a stand-alone plumbing permit. The City's 2026 fee schedule prices plumbing fixtures at $23.20 each in a single family dwelling and $30.94 each in all other buildings. A minimum fee of $214.79 applies to all work, so a single fixture alone pays the $214.79 minimum.

Buried piping has its own line. For a single family house, the schedule sets a $214.79 flat fee for repairs, replacement and additions of buried plumbing and drainage piping. Ask about that line if the new drain runs under a basement or ground-floor slab.

Work that also alters walls or finishes is an interior alteration, which the schedule lists as partitions and finishings. The City's 2026 rate for a residential building, Group C, is $11.53 per square metre, counted over the total area affected by the proposal. A 12 square metre kitchen alteration calculates to about $138, under the minimum. The City's interior alterations guide asks for any plumbing to be submitted on a Plumbing Data Sheet with that building permit application.

Construction without a permit carries its own charge. The City's schedule sets it at 50% of the permit fee or $214.79, whichever is greater, up to $29,456.99 per permit.

Adept's cost guide prices a City building permit for wall removal, structural beams or layout changes at $400 to $2,500. It puts a plumbing permit at $150 to $400, and the low end of that range is below the City's minimum. For a sink move alone, the City's schedule sets the fee.

Under the Ontario Electrical Safety Code, electrical work must be reported to the Electrical Safety Authority by filing a notification of work before the work starts. ESA says whoever is doing the electrical work must be the one to file it. A kitchen that adds a receptacle for an island needs that notification, even when the countertop itself needs nothing.

ESA names one warning sign for homeowners. It is a red flag if a contractor asks you to file a notification of work in your own name, because the contractor could be unlicensed. Who may do electrical work at all is covered in is countertop installation a licensed trade in Ontario. On a countertop job the question comes up when an outlet is added for an island or a cooktop circuit is altered for a new cut-out.

Adept reports that on a condo kitchen renovation, the board or condo management approval process adds 2 to 4 weeks and often requires proof of insurance and WSIB. Its condo advice is to keep the sink and stove where they are. It names moving a sink through a concrete slab as the single biggest cost driver in a condo kitchen, often $5,000 to $10,000 alone.

Whether a countertop-only swap needs the building's approval depends on the building, so ask the property manager before booking the template. Raise a sink move first, since it can mean cutting through the slab. Elevator booking, deposits, working hours and getting the slab into the building are covered in installing a countertop in a Toronto condo.

For a permit-free swap the calendar is short. Josh Kitchen puts custom fabrication at one to two weeks after measuring. Installation takes one day, and the kitchen is typically unusable for one to two days. The same guide allows one to two extra days if plumbing or electrical work is involved. Teccorp Stone, a Toronto countertop company, says final sink and appliance specifications should be available before templating to reduce the risk of revisions or re-fabrication. If a permit is needed, make sure the templated sink position matches the one in the application. The full sequence is in how long a countertop job takes in the GTA.

For a one- or two-unit house, a plumbing permit is filed with a Plumbing Data Sheet. The City says no plumbing plans are required for those houses unless the project includes a reverse-sloping driveway. All other residential plumbing and drain permit applications must include drawings showing the layout of plumbing and related fixtures on each floor level. An interior alteration permit needs its own drawings, drawn to scale, fully dimensioned, signed and dated. The application is signed by the owner or the owner's authorized agent.

The City's Express Services list includes stand-alone plumbing and drain permits and interior alterations for a Part 9 house with up to two dwelling units and no active building permit for a new residential building or addition. Toronto Building's goal is to review eligible applications within 3 business days after intake, which makes Express the likely route for a sink move in such a house. House projects that do not qualify for Express go to the House Stream, reviewed within 10 business days once complete. The City counts those applications complete only when they include an issued Zoning Applicable Law Certificate.

Permitted work is inspected. The City says inspectors must be able to see the part of the work under inspection. Anything covered before its mandatory inspection will have to be uncovered for inspection and passed. If the moved drain has a mandatory inspection, book it before the new countertop and sink cover it. The order of trades on install day is in who disconnects the plumbing on countertop installation day.

No listing among the 876 in the index records who handles permits, ESA filings, inspections or gas work. Put these questions to the installer:

• Does the sink, a dishwasher or the cooktop move, or does everything go back in place?
• If a City permit is needed, who applies for it?
• Who books the City inspection, and will it happen before the new top goes on?
• If any electrical work is involved, who files the ESA notification of work?
• Who disconnects and reconnects the gas cooktop, and are they TSSA-registered?
• In a condo, does the building need to approve the work?

The fee schedule and review times in this article are the City of Toronto's. North York and Scarborough are inside the City of Toronto. Vaughan, Mississauga and Brampton each sit outside it, so a homeowner there should check with their own municipality's building department before work starts.

The electrical rule does not change at the city line. ESA's notification requirement comes from the Ontario Electrical Safety Code, which applies across Ontario.
