OUR STORY
About Yok Mei Construction Corp.
15 Years of Building Trust in Markham and York Region
Yok Mei Construction Corp. started with a simple belief: homeowners deserve a general contractor in Markham who shows up, communicates clearly, and finishes the job right. That belief has guided every project we have taken on since day one. From our first kitchen renovation in Unionville to our most recent basement suite conversion in Cornell, we have built our reputation one project at a time.
We are not a franchise. We are not a sales operation that subs out every trade to the lowest bidder. We are a family-run construction company based at 91 Cottsmore Crescent in Markham, and we treat every home we enter like it is our own. Our crew lives in the communities we serve. Our kids go to the same schools as our clients kids. We have a vested interest in doing work that makes this city better.
Over the past 15 years, we have completed hundreds of projects across Markham and York Region. We have worked on heritage homes in Unionville where every detail had to be approved by the heritage conservation district, and we have built modern open-concept kitchens in Cornell where speed and efficiency were the priorities. We have finished basements in Milliken that now generate rental income for young families, and we have added second floors to bungalows in Berczy Village that gave growing families the space they needed without leaving the neighbourhood they loved.
Our process has been refined through every project. We know that the best renovations start with honest conversations — about budget, timeline, and what is actually possible within the constraints of your home and the local building code. We do not oversell. We do not cut corners. And we do not disappear when problems arise. That is why our clients come back to us for second projects, and why they recommend us to their friends and family.
If you are looking for a Markham general contractor who treats your home with the same care they would give their own, we would love to talk. Start with a free estimate and see why homeowners across the city keep recommending us to their neighbours.

Smart Decisions
Should You Hire a General Contractor or DIY Your Renovation?
Why DIY Renovations Often Cost More in the Long Run
DIY projects seem cheaper on paper, but they come with hidden risks that can cost you far more than hiring a general contractor in Markham. When you manage your own renovation, you're responsible for sourcing materials, scheduling trades, pulling permits through the city's ePLAN system, and coordinating inspections with York Region Building Standards. One missed inspection or incorrect permit can delay your project by weeks.
We've been called in to fix DIY projects gone wrong — improperly installed load-bearing walls, electrical work that failed inspection, and basement waterproofing that led to mold. These fixes always cost more than doing it right the first time.
01
Permit knowledge: A general contractor knows which projects need permits and how to navigate the ePLAN portal efficiently.
02
Trade coordination: We schedule electricians, plumbers, and HVAC techs so no one is waiting around.
03
Code compliance: Every project meets Ontario Building Code, protecting your home's value and your family's safety.
04
Insurance coverage: If something goes wrong on a DIY project, your homeowner's insurance may not cover it. Our $2M liability policy protects you.
05
Time savings: What takes a homeowner 6 months of weekends takes our crew 4–6 weeks of focused work.
If your project involves structural changes, electrical work, plumbing, or basement finishing, hiring a licensed general contractor isn't just recommended — it's the smart financial decision.
Local Expertise
Markham Building Permits & Regulations
When Do You Need a Permit for Your Renovation?
The City of Markham requires permits for most structural, electrical, plumbing, and HVAC work. If you're removing a load-bearing wall, finishing a basement, adding a bathroom, or extending your home, you need a permit. Even replacing windows in some heritage areas of Unionville requires approval.We handle the entire permit process through the city's ePLAN online portal. This includes preparing architectural drawings, submitting applications, paying fees, and scheduling inspections with York Region Building Standards. Most homeowners find the ePLAN system confusing — we've submitted hundreds of applications and know exactly what documentation inspectors want to see.
Common Permit Requirements in Markham
→
Basement renovations: Egress windows must meet minimum size requirements (0.35m² clear opening), ceiling height must be at least 1.95m, and fire separation between units is mandatory for legal secondary suites.
→
Kitchen renovations: Electrical upgrades require ESA inspection. Gas line modifications need a TSSA-licensed technician.
→
Bathroom renovations: Waterproofing must extend 150mm above showerheads. Drainage slopes must meet Ontario Building Code minimums.
→
Home additions: Setback requirements vary by zoning. Unionville heritage districts have additional design guidelines.
→
Condo renovations: Most buildings require alteration agreements, insurance certificates, and designated work hours.
If your project involves structural changes, electrical work, plumbing, or basement finishing, hiring a licensed general contractor isn't just recommended — it's the smart financial decision.
2026 Insights
Markham Home Renovation Trends for 2026
Legal Basement Suites Are in High Demand
With rental rates climbing across York Region, more homeowners are converting unused basements into legal secondary suites. The City of Markham has streamlined the permit process for compliant basement apartments, making this one of the highest-ROI projects you can undertake. A properly finished basement with a separate entrance, kitchenette, and full bathroom can generate $1,500–$2,200 per month in rental income. We handle the egress window installation, fire separation, and ceiling height compliance so your suite passes inspection on the first try.
Open-Concept Kitchens Remain the Top Request
Kitchen renovations continue to dominate our project list. Homeowners in Cornell, Berczy Village, and Angus Glen are removing walls between kitchens and living rooms to create open, flowing spaces. Quartz countertops in white and grey tones remain the most popular choice, paired with custom shaker-style cabinetry and large kitchen islands with waterfall edges. Smart appliances and under-cabinet LED lighting are also trending features that add functionality without breaking the budget.
Spa-Style Bathrooms With Heated Floors
Walk-in showers with frameless glass enclosures, freestanding soaker tubs, and heated tile floors are no longer luxury items — they're standard requests in master bathroom renovations. Homeowners in Milliken and Unionville are upgrading en-suite bathrooms to create private retreats. Heated floors are especially popular given Ontario's cold winters, and they're more affordable than most people expect.
Energy-Efficient Upgrades for Long-Term Savings
With energy costs rising, more homeowners are incorporating efficiency into their renovation plans. This includes upgrading insulation during basement finishing, installing energy-efficient windows during home additions, and switching to LED lighting throughout the house. These upgrades reduce utility bills and increase resale value — a win-win that pays for itself over time.
Home Offices and Multi-Functional Spaces
The shift to remote and hybrid work has permanently changed how people use their homes. Basement renovations now regularly include dedicated home offices, soundproofed Zoom rooms, and multi-functional guest suites. A well-designed home office adds value whether you work from home full-time or just need a quiet space for focused work.
Outdoor Living Spaces Are Expanding
Homeowners in Angus Glen and Cachet are increasingly investing in outdoor kitchens, covered patios, and landscaped entertainment areas. These spaces extend the usable square footage of a home and create year-round gathering areas for family and friends. We design outdoor living spaces that complement the architecture of your home and withstand Ontario variable climate — from hot summers to freezing winters.
Aging-in-Place Modifications
As more families choose to stay in their homes long-term, accessibility features are becoming standard in renovation plans. Walk-in showers with grab bars, wider doorways, main-floor bedrooms, and lever-style handles are practical upgrades that add value for every stage of life. We incorporate these features seamlessly into bathroom and whole-home renovations without making them feel clinical or institutional.
The Big Question
Should You Renovate Your Home or Move to a New One?
When Renovating Makes More Sense Than Moving
Moving in today's market means paying land transfer taxes, real estate commissions, moving costs, and potentially higher mortgage rates. For many homeowners in Markham, renovating the home you already love is the smarter financial move. A well-planned kitchen renovation can return 75–85% of its cost at resale. A finished basement with a legal rental suite can generate $1,500–$2,200 per month in rental income.If you love your neighbourhood, your commute, your schools, and your neighbours, staying put and improving your space often delivers better value than starting over somewhere new. We've helped dozens of families in Berczy Village, Cornell, and Angus Glen add the space they need without giving up the community they've built.
Signs It's Time to Renovate
01
Your layout doesn't work anymore. Growing families in Milliken bungalows often need an extra bedroom or a more functional kitchen. A home addition or main-floor reconfiguration solves this without relocating.
02
Your home is outdated but structurally sound. If the bones are good, a whole-home renovation can transform a 1980s house into a modern, energy-efficient home for less than the cost of buying new.
03
You need rental income. With housing costs rising, legal basement suites are one of the best investments you can make. We specialize in secondary suite conversions that meet all Ontario Building Code requirements.
04
You're planning to sell in 3–5 years. Strategic updates — kitchen refreshes, bathroom upgrades, and curb appeal improvements — can significantly increase your sale price when the time comes.
When Moving Might Be the Better Option
If your home has structural issues, foundation problems, or is in a flood zone, moving might be the wiser choice. But for most homeowners in established neighbourhoods like Unionville and Thornhill, the homes are well-built and the locations are desirable. A conversation with our general contractor team can help you understand what's possible within your budget — sometimes the right renovation changes everything.
