New cabinets in the same layout: no city we checked asks for a building permit. Move the sink, take down a wall or add a circuit, and the paperwork changes. Here is what twelve GTA municipalities, the ESA and Ontario’s gas rules actually say — quoted, with links.
Your neighbour says nobody gets a permit for a kitchen. Your contractor says it depends. A forum thread says you will be fined. All three are describing the same rule from different ends: in Ontario, swapping cabinets in the same layout is something no city we checked asks a permit for — and moving the sink, taking down a wall or adding a circuit is a different job, with different paperwork, even though it happens in the same week.
We read the official building-permit pages of twelve GTA municipalities, from Toronto and Mississauga to Aurora and Georgina. Every one that addresses kitchens lists replacing cabinets or cupboards as work that does not need a building permit, and most add replacing a plumbing fixture in the same spot. The things that turn a kitchen into permit work are just as consistent:
Two more tracks run alongside the building permit and are easy to miss. Electrical work is reported to the Electrical Safety Authority, not the city — a city saying “no building permit for electrical” does not mean no paperwork. And gas work is licensed work, full stop. Both are in section 04.
What they search at midnight “do i need a permit to renovate my kitchen in ontario” — typed the night before demolition, which is about four weeks too late for the answer to be convenient.
The Building Code Act, 1992 is short on this point: “No person shall construct or demolish a building or cause a building to be constructed or demolished unless a permit has been issued therefor by the chief building official.” Two definitions do the work. To construct includes “material alteration or repair of a building”, and a building includes “all plumbing, works, fixtures and service systems appurtenant thereto.” That is why moving a drain is permit work even when no wall moves.
Permits are issued by your municipality, not the province — “building permit applications are submitted to your municipality, not to the provincial government,” as Ontario’s own guide puts it — which is why the lists below differ in their details. The province is also clear about whose job the permit is: “It’s your responsibility to get building permits and meet any legal requirements you’ll need to renovate. If you want the contractor to get permits on your behalf, make sure it’s spelled out in the contract and don’t allow construction to begin until you’ve seen them.”
In a condo there is a fourth layer, the corporation’s own approval, which is separate from all of this. Renovating a condo kitchen in Toronto.
| The work | Building permit? | Also needed |
|---|---|---|
| New cabinets in the same layout | No, on every GTA list we read | Condo approval, if you are in one |
| New countertop, same place | Aurora lists “Installation of counters” as no-permit; most cities do not mention counters at all | If the sink moves with it, see the next rows |
| New sink, tap or dishwasher in the same spot | Usually no — “Repairing and replacing plumbing fixtures” (Toronto) | Some cities, Markham and King among them, treat repairs to the drain piping itself as permit work |
| Moving the sink, adding a fixture, new drains | Yes — new or relocated plumbing is on every list that mentions plumbing | Ask whether you or a licensed plumber may do it |
| Removing or adding a wall | Yes — structural work everywhere; in Markham, even a non-loadbearing partition | Someone to confirm whether it carries load |
| New circuits, outlets moved, new lighting | Usually not a building permit | An ESA notification, filed before work starts |
| Moving or connecting a gas range | A separate, licensed track | A certified gas technician; no homeowner exception |
| A range hood ducted outside | Ask — Mississauga and Oakville list “Kitchen exhaust” among permit items, without saying whether that includes a home hood | A route through the wall; in a condo, the building’s say |
This table summarises the official lists; it is not a ruling on your project. Toronto’s page adds that its list “is not exhaustive and judgment should be used.” When in doubt, the building department answers the question for free.
Quoted from each city’s own building-permit page, checked October 2026. Each one also takes applications online through the portal linked from that page.
| Municipality | Listed as not needing a permit | Listed as needing one |
|---|---|---|
| Toronto | “Installation of cabinetry and millwork”; “Repairing and replacing plumbing fixtures” | “adding or removing walls”; “Install or modify heating and or plumbing systems” |
| Mississauga | “Cabinetry or cupboards”; fixture replacement “in the same location” | “Interior alterations”; a fixture “added, removed or relocated”; “Plumbing drainage – install, replace or repair” |
| Brampton | “install kitchen or bathroom cupboards without changes to the existing plumbing” | See the city’s homeowner permit packages, including minor interior alterations and plumbing |
| Oakville | “Permits typically are not required for replacing existing cabinetry, sinks, faucets, toilets and cosmetic changes to surfaces.” | “wall removals … adding new or relocating plumbing fixtures” |
| Markham | “Kitchen or bathroom cupboards”; “Replacing plumbing fixtures or water heaters” | Structural walls; “a non-loadbearing partition”; “Installing any new plumbing piping” |
| Richmond Hill | “Installing kitchen or bathroom cupboards” | “Altering the interior of a building”; “Altering or remodelling a plumbing and/or HVAC system” |
| Aurora | “Replacement of kitchen and bathroom cupboards without plumbing work”; “Installation of counters, millwork and floor finishing” | Plumbing changes may need “a separate plumbing permit” — ask |
| Newmarket | Cabinets not mentioned; “Floor and ceiling finishes” and “Painting or decorating” typically need none | “Walls – adding or removing”; “Mechanical alterations (HVAC/plumbing)” |
| Whitchurch-Stouffville | “Kitchen cabinetry replacement, as long as any plumbing is not relocated or replaced” | Construction, demolition or renovation generally; replacing a load-bearing wall with a beam |
| King | “Kitchen or bathroom cupboards”; “Replacement plumbing fixtures” | “Install new plumbing”; “Add or remove a structural wall”; altering or repairing the plumbing system |
| East Gwillimbury | Cupboards “where no plumbing alterations are proposed”; “Repair or replacement of a plumbing fixture” | “most construction, renovation, or demolition projects” |
| Georgina | “Replace kitchen and bathroom cupboards without plumbing work”; fixture replacement where plumbing is not altered | “Changing adding or removing plumbing from a kitchen or bathroom” |
Two patterns are worth noticing. Several towns tie the cabinet exemption to the plumbing — “without plumbing work”, “without changes to the existing plumbing” — so a kitchen where the sink moves is a permit job even if nothing else changes. And a few, Markham, King, Mississauga and Oakville among them, count repairs to drain piping as permit work, which is stricter than Toronto’s list. Vaughan, Pickering, Ajax and the other GTA municipalities publish their own lists; look up your own before you plan.
What the permit buys you is mostly timing. The inspection happens while the walls are open, which is the one moment anyone can see the work. Where the inspection sits in the order of a renovation.
The building department can only answer the question you actually ask. “I’m redoing my kitchen” gets “it depends”. “The cabinets stay on the same walls, the sink moves 30″ to the left on the same wall, the wall between the kitchen and dining room comes out, and we’re adding two counter circuits” gets a straight answer — and tells you which parts are permit work and which are not.
Most of that list is answered by a plan. Draw the room as it is in our free planner, place the cabinets where they are going, and the drawing shows at a glance whether the sink has moved and which walls carry new work. ⬇ Export builds a PDF with the top view, the countertop dimension drawing, a 3D view and the elevations — the same set you will hand the contractor, the countertop shop and, in a condo, the management office. It runs in a browser and you can start without an account.
Quotes are taken from official pages, checked October 2026. Municipal pages change, and each says its list is not exhaustive; your building department has the final word.
Not if the layout and the plumbing stay the same, according to every GTA municipality we checked. Toronto lists “Installation of cabinetry and millwork” as work that does not need a building permit, and Mississauga, Markham, Richmond Hill, Aurora, King, Georgina and others say the same about kitchen cupboards. Several attach a condition: no plumbing work. Permits are issued by your municipality, so check its page if you are outside the cities we list.
Usually yes. Moving a sink means new or relocated drain and supply piping, and the Building Code Act counts plumbing as part of the building. Mississauga lists a fixture that is “added, removed or relocated” as permit work, Markham lists “Installing any new plumbing piping”, and Toronto lists work to “Install or modify heating and or plumbing systems.” Replacing a sink or tap in the same spot generally does not need one.
Yes. Every GTA list we read treats adding or removing walls, and anything structural, as permit work. Markham goes further and includes altering a non-loadbearing partition. Before anything comes down, someone qualified has to confirm whether the wall carries load.
Usually not a building permit, but almost always an Electrical Safety Authority notification. ESA says the electrical code “requires almost all electrical work be reported” and that “Having a building permit isn’t the same as filing an electrical notification. You may need both.” The notification is filed before the work starts.
In your own home, yes, if you file a notification with ESA first. ESA puts it as “Only you can do electrical work in your home, but you must file a notification with ESA,” and adds that friends, family members or neighbours cannot do it for you. Anyone you hire must be a Licensed Electrical Contractor. A condo’s own rules may require a licensed electrician regardless.
No. Ontario’s gaseous fuels regulation says no person shall install, alter, repair or remove a gas appliance unless they hold a certificate for that purpose, and there is no homeowner exception. Use a TSSA-registered contractor with a certified gas technician.
A countertop replaced in the same place is not on any permit list we read, and Aurora lists “Installation of counters, millwork and floor finishing” as work that needs no permit. Most cities simply do not mention counters. If the sink moves with the new countertop, the plumbing rules apply to that part.
Ontario puts the responsibility on the owner: “It’s your responsibility to get building permits and meet any legal requirements you’ll need to renovate.” If you want the contractor to pull them, the province advises writing that into the contract and not letting construction begin until you have seen the permits.
Yes, the same building and electrical rules apply inside a condo suite, and the condo corporation’s approval is a separate requirement on top. Many buildings also set their own rules on plumbing, electrical trades, work hours and elevator use.
Draw the kitchen you have and the one you want, and the permit question mostly answers itself: which walls move, where the sink goes, what is new. Free, in a browser.
