In Markham, a kitchen renovation typically lands somewhere between $20,000 for a same-layout refresh and $150,000+ for a full custom rebuild — and the gap between those numbers is almost entirely about scope, not the contractor. Here's how the real ranges break down, and what actually pushes a job from one bracket to the next.
What a real job costs, by scope
"Kitchen renovation cost" isn't one number, because a like-for-like cabinet swap and a full layout change with moved plumbing aren't the same project:
- Cosmetic refresh (same layout, new cabinet fronts or stock cabinets, new countertop, backsplash, flooring — no plumbing or electrical moved): typically $20,000–$40,000. This is also the tier that generally doesn't require a building permit, as long as nothing structural, plumbing, or electrical-capacity related changes.
- Mid-range renovation (new semi-custom cabinets, quartz counters, updated plumbing and electrical within the existing footprint, possibly a moved sink or island): typically $40,000–$75,000.
- Full gut / layout change (moved plumbing fixtures, a removed or altered load-bearing wall, upgraded electrical service, custom cabinetry): typically $75,000–$150,000+. This is the tier where permits, a structural engineer, and multiple inspections become part of the timeline, not just the budget.
All of these figures are pre-tax. On a $60,000 project, Ontario's 13% HST adds roughly $7,800 — worth confirming up front whether a quote is showing you the number before or after tax, since that gap gets mistaken for a mid-project price increase more often than it should.
Why Markham sees more wall-removal projects than a newer build
A meaningful share of Markham's housing stock predates the open-concept layouts that are standard in newer construction — kitchens closed off from a formal dining room or living room by a load-bearing wall, sized for a much smaller range of appliances and cabinetry than most homeowners want today. That's the practical reason a Markham kitchen project lands in the full-gut bracket more often than a five-year-old build's would: the wall itself, not the cabinets or counters, is frequently the thing actually driving the budget up.
When Markham actually requires a permit
A straight cosmetic refresh — paint, hardware, a like-for-like cabinet swap, a new countertop or backsplash on the existing footprint — generally does not require a building permit. A permit is required once the work involves relocating plumbing fixtures, altering a load-bearing wall, or increasing electrical service capacity. If a load-bearing wall is involved, the City of Markham requires a structural engineer to design and stamp the change before a permit is issued — that's not optional paperwork, it's a real safety requirement, and it's the single most common permit trigger in an older Markham kitchen specifically.
Markham's building permit fees are assessed per square metre of the area being renovated — on the City's published fee schedule, $4.50 per square metre of renovated gross floor area — so a typical kitchen's permit fee is modest next to the project itself, though larger structural changes add new-floor-area charges on top. Applications are filed and reviewed online through the City's building permit portal (Markham ePLAN), which moved to fully digital submission for residential permit applications in 2025. Ontario's Building Code Act sets a statutory maximum of 10 business days once a complete application is submitted — plan on that lead time before demolition starts, not after. Once work begins, expect scheduled inspections at rough-in stages (plumbing, electrical, framing) before drywall closes the walls back up, plus a final inspection to close out the permit.
The HST rebate most homeowners assume doesn't apply
Ontario has an enhanced new housing rebate for a "substantial renovation" — generally defined as removing or replacing at least 90% of a home's interior. A kitchen renovation on its own, even a full gut, does not meet that bar and does not qualify for the rebate by itself. It only comes into play if the kitchen work is part of a much larger whole-home renovation. Don't let a quote imply otherwise.
What actually moves the number
The fastest way to know which bracket your Markham project actually falls into is to ask directly: is anything structural changing, is any plumbing or electrical being relocated, and is the quote before or after HST. Those three answers explain most of the spread between a $25,000 kitchen and a $100,000 one — far more than which contractor you pick.
