A kitchen renovation in Markham usually starts with a wish for more light, better flow, and a layout that matches how your family cooks and gathers. Whether you live in Unionville, Cornell, Markham Village, Wismer, Berczy, or Angus Glen, many homes here were built from the 1970s through the 2010s with a closed kitchen, a breakfast nook, and a family room just past a wall. Opening that up, adding an island, or moving appliances can transform how the house works, but it also brings structure, City of Markham permits, and trade coordination into the picture. This guide covers what to plan first, based on about 20 years of hands-on construction and roughly 15 years as a home inspector in Ontario.

Key Takeaways

  • Decide on the layout before choosing cabinets or finishes. Layout drives structure, plumbing, electrical, and venting.
  • Removing or changing a load-bearing wall needs an engineered beam design and a City of Markham building permit.
  • New circuits and panel work need an ESA notification filed by a Licensed Electrical Contractor.
  • Moving a gas range requires a TSSA-registered gas contractor and a properly sized, properly vented range hood.
  • An inspection-minded walkthrough before demolition finds old leaks, weak subfloors, and wiring issues early.

What should you decide first in a Markham kitchen renovation?

Start with how you use the room. Count how many people cook at once, where kids do homework, how much pantry storage you need, and whether you want seating at an island. Then sketch the work zones: sink, cooktop, fridge, prep space, and landing space beside each appliance. Once the layout is settled, the rest of the decisions follow. Picking cabinets first and forcing the layout around them is one of the most common causes of change orders.

Keep the sink near its current drain if you can. Moving it a few feet along the same wall is usually simple; moving it to an island means a new drain and vent across the floor framing, which needs planning and often a permit.

Can you remove the wall between the kitchen and family room?

Often yes, but it depends on what the wall carries. In many two-storey Markham homes from the 1970s through the 2010s, that wall supports floor joists or a bearing point from above. Removing it means a properly sized beam with posts down to the foundation, an engineered design, and a City of Markham building permit.

Walls can also hide ductwork, plumbing stacks, gas lines, or wiring. We check what is inside before promising an open concept, so the plan you approve is the plan that gets built.

Which kitchen work needs a permit in Markham?

Work City permit? Other approvals
New cabinets and counters in the same layout Usually no None in most cases
Removing or altering a load-bearing wall Yes Engineered beam design
Moving the sink or adding an island sink Usually yes Drain and vent design to code
New circuits, lighting, or panel upgrade Not a building permit item ESA notification by a Licensed Electrical Contractor
Moving or adding a gas line Check with the city TSSA-registered gas contractor
New exterior vent or window change Often yes Check clearances to windows and doors

Permit rules can change, so confirm your exact scope with the City of Markham Building Standards department before work starts. We help prepare the information the city asks for.

What electrical upgrades does a modern kitchen need?

Modern kitchens draw a lot of power. Induction cooktops, wall ovens, dishwashers, and fridge drawers often need dedicated circuits. Counter receptacles must meet Ontario Electrical Safety Code spacing and protection rules. Older panels in 1970s and 1980s Markham homes may not have room, so a panel review is part of planning. A licensed electrician does the work and files the ESA notification before starting.

How should a range hood be vented?

Vent to the outside, not back into the room. Size the hood to the cooktop, use smooth metal duct with few elbows, and terminate at a proper exterior cap. Large hoods can pull air out of a tight house and affect fuel-burning appliances, so review make-up air with the furnace and water heater venting. Home inspection experience helps here: we look at the whole house, not just the kitchen.

What hidden problems show up when Markham kitchens are opened up?

Common finds include soft subfloors from slow sink or dishwasher leaks, old flexible supply lines, overloaded circuits, missing dishwasher air gaps or high loops, and ductwork in walls planned for removal. Because Nehan Construction also does home inspections, we look for these before demolition so they are priced and scheduled, not discovered mid-job.

Markham Kitchen Renovation Checklist

  • List how you cook, eat, store, and gather in the kitchen.
  • Settle the layout and work zones before choosing cabinets.
  • Confirm whether any wall to be removed is load-bearing.
  • Get an engineered beam design and a City of Markham permit if needed.
  • Review panel capacity and plan dedicated appliance circuits.
  • Plan range hood size, duct route, and exterior termination.
  • Use a TSSA-registered gas contractor for any gas changes.
  • Order cabinets and long-lead items early.
  • Set up a temporary kitchen elsewhere in the house.
  • Get a clear written scope and schedule before demolition.

How long does a kitchen renovation in Markham take?

A same-layout refresh moves faster than a project that opens walls or moves plumbing. Permit review, engineering, and cabinet lead times usually set the start date. We give you a realistic written schedule after a site visit, once we know the scope and what is behind the walls.

Why work with a licensed contractor on your Markham kitchen?

Nehan Construction is led by a licensed contractor with about 20 years of hands-on construction experience and construction engineering training from George Brown College (Building Renovations). He also brings roughly 15 years of home inspection experience and is among the top inspectors in Ontario. We are fully insured with WSIB coverage, use licensed electrical, plumbing, and HVAC subcontractors, and build to the Ontario Building Code. Low overhead keeps pricing fair.

Frequently Asked Questions

Do I need a permit for a kitchen renovation in Markham?

Not for a like-for-like cabinet and counter replacement in most cases. Removing a load-bearing wall, moving plumbing, or some exterior changes usually need a City of Markham building permit. Electrical work needs an ESA notification.

Can I add an island with a sink?

Usually, yes. It needs a new drain and a code-compliant vent solution run through the floor, so it should be planned early and may need a permit.

Is the wall between my kitchen and family room load-bearing?

It often is in two-storey homes. A site visit, and an engineer where needed, confirms what the wall carries and what beam is required.

Should my range hood vent outside?

Yes. An exterior-vented hood removes moisture, grease, and cooking fumes. Large hoods should be reviewed for make-up air.
