If you live in Cornell, Greensborough, Wismer, or Box Grove and you're trying to squeeze a second or third car onto your property — you're not alone. Parking pressure in Markham's packed subdivisions is real. But so is By-Law 2006-96, and the City enforces it. At Cedarwood Development Group Inc., we design and build interlocking driveway extensions that give Markham homeowners the parking they need while staying 100% compliant — so you never have to worry about a by-law officer knocking at your door.

What Is Markham By-Law 2006-96?
By-Law 2006-96 is the City of Markham's primary regulation governing driveway extensions, front-yard hardscaping coverage, and soft landscaping minimums on residential properties. It was introduced to protect neighbourhood aesthetics, manage stormwater runoff, and prevent the complete paving-over of front yards that had become common in high-density subdivisions.
The by-law applies across all of Markham — including every subdivision from Cornell to Greensborough, Wismer to Box Grove, Cathedral to Angus Glen. If you are adding, widening, or extending a driveway or adding interlocking to your front yard, this by-law applies to your project.
Markham By-Law 2006-96 limits driveway extensions to 2 metres beyond the garage width, caps total driveway width at 50% of lot frontage or 6.71 metres (whichever is less), and requires a minimum percentage of the front yard to remain as soft landscaping depending on lot width.
The Key Rules: What By-Law 2006-96 Actually Says
📏
Maximum extension beyond garage
2 metres (6'6")
You can only extend your driveway up to 2m wider than your garage opening — no more.
🚗
Maximum total driveway width
50% of lot frontage or 6.71m
Whichever is less applies. On a standard Markham semi, this is often the binding limit.
🌿
Soft landscaping — narrow lots
25% of front yard
For lots less than 10.1m wide, at least 25% of the front yard must stay as grass, shrubs, or garden beds.
🌳
Soft landscaping — wider lots
40% of front yard
For lots greater than 10.1m wide, 40% of the front yard must remain soft landscaping.
Important: Interlocking stone and concrete pavers are classified as hardscaping in Markham — not soft landscapin
g. They do not count toward your minimum softscape requirement, even though they look like natural stone. Artificial turf is also considered hardscaping under Markham's rules.
Lot Size Scenarios: What You Can Build in Markham Subdivisions
The rules land differently depending on your lot size. Here's how By-Law 2006-96 plays out across the most common Markham subdivision lot types.
Lot type | Lot frontage | Max driveway width | Min soft landscaping | Typical outcome |
Townhouse / freehold town | ~6–8m | 3.0–4.0m (50% rule) | 25% of front yard | Very limited widening possible — design matters most |
Semi-detached | ~8–10m | 4.0–5.0m (50% rule) | 25% of front yard | Single-wide extension possible with proper planning |
Standard detached | ~10–13m | Up to 6.71m (width cap) | 40% of front yard | Double-wide driveway achievable on most lots |
Large detached / estate | ~14m+ | 6.71m maximum | 40% of front yard | Full double driveway with landscaped border possible |
*Always verify your specific lot dimensions with the City of Markham before starting any project. Cedarwood measures every property before designing.
Common Markham Subdivisions and What Homeowners Are Asking
These are the Markham neighbourhoods where we receive the most driveway widening inquiries — and the specific challenges each one presents.
Neighbourhood | Common lot type | Most common challenge |
Cornell | Freehold towns and semis | Narrow frontages make full widening difficult — creative stone border designs help maximize visual width within limits |
Greensborough | Mix of semis and detached | Shared driveways and close lot lines — side extensions require careful measurement |
Wismer Commons | Detached on standard lots | Softscape minimums on wider lots — balancing driveway expansion with required green space |
Box Grove | Larger detached homes | More room to work with — popular for full double driveway with natural stone borders |
Angus Glen / Cathedral | Estate and large detached | Premium finishes expected — natural stone and complex patterns within by-law limits |
Berczy Village | Mix of towns and detached | Heritage design guidelines may apply on some streets — we verify before designing |
What Happens If You Violate By-Law 2006-96?
Markham's by-law enforcement team actively patrols subdivisions and responds to neighbour complaints. Violations are taken seriously. Here's what non-compliance can cost you:
✕ City-issued fines — Markham can issue fines for non-compliant hardscaping. The cost of compliance after the fact almost always exceeds the cost of designing it right from the start.
✕ Mandatory removal orders — The City can order you to remove non-compliant interlocking or hardscaping at your own expense, which means paying twice for the same job.
✕ Issues at resale — Non-compliant driveway work can flag during a home inspection or real estate transaction, potentially delaying or complicating your sale.
✕ Drainage complaints — Excessive hardscaping that diverts stormwater onto neighbouring properties can result in civil complaints and additional City involvement.
How Cedarwood Designs Compliant Driveway Extensions in Markham
The good news is that By-Law 2006-96 does not stop you from adding parking space — it just defines the boundaries you have to work within. Our job is to design the most functional, beautiful interlocking driveway possible within those boundaries.
Our by-law compliant design process
1 Property measurement and lot verification
We measure your lot frontage, current driveway width, garage opening, and front yard dimensions before any design work begins. We calculate exactly how much width you can legally add and how much soft landscaping must remain.
2 Compliant design that maximizes your space
Within your legal limits, we design driveway extensions that feel spacious, look premium, and make the most of every square metre available. Strategic stone patterns and border work can make a compliant driveway look wider than the numbers suggest.
3 Soft landscaping integration
We don't just build the hardscape — we help you plan the required soft landscaping so it looks intentional, not like an afterthought. A well-placed garden bed or shrub border satisfies the by-law and elevates your curb appeal at the same time.
4 Licensed contractor status
The City of Markham requires driveway paving contractors to be licensed by the City. Cedarwood Development Group is a licensed and insured contractor — so your project is protected and by-law compliant from day one.
5 Premium interlocking materials and installation
We install concrete pavers, natural stone, and tumbled stone driveways using proper base preparation, drainage planning, and edge restraints — built to last through Markham's freeze-thaw seasons without shifting or settling.
Interlocking vs. Asphalt for Markham Driveway Widening
Both interlocking and asphalt are permitted under By-Law 2006-96. But for driveway widening projects in Markham subdivisions, interlocking offers significant advantages:
Better drainage — permeable interlocking options reduce stormwater runoff, which matters under Markham's drainage rules
No curing time — interlocking is immediately usable after installation, unlike asphalt which needs days to cure
Easier repairs — individual pavers can be lifted and replaced if underground work is ever needed, without repaving the entire surface
Higher property value — interlocking consistently adds more curb appeal and resale value than asphalt in Markham's market
Design flexibility — patterns, colours, and borders can visually widen a driveway beyond its physical limits

Frequently asked questions: Markham driveway widening and By-Law 2006-96
How wide can I make my driveway in Markham?+
Under By-Law 2006-96, your driveway total width cannot exceed 50% of your lot frontage or 6.71 metres — whichever is less. You also cannot extend more than 2 metres (6'6") beyond the width of your garage opening. On a typical Markham semi-detached home with an 8–9m frontage, that means a maximum driveway of roughly 4.0–4.5m total width.
Do I need a permit to widen my driveway in Markham?+
You do not typically need a building permit for a driveway extension in Markham, but the work must comply with By-Law 2006-96 regardless. The City also requires that driveway paving work be performed by a City of Markham licensed contractor. Cedarwood Development Group holds the required contractor licence. If a curb cut modification is needed, additional City approval is required.
How much of my Markham front yard must stay as grass or landscaping?+
It depends on your lot width. For lots less than 10.1 metres wide, at least 25% of the front yard must remain as soft landscaping — meaning real grass, shrubs, garden beds, or similar plantings. For lots greater than 10.1 metres wide, the minimum is 40%. Interlocking stone, concrete pavers, and artificial turf do not count as soft landscaping under Markham's rules.
Does interlocking count as soft landscaping in Markham?+
No. Interlocking stone is classified as hardscaping under Markham's by-laws, not soft landscaping. It does not count toward your minimum softscape requirement. This is a common misconception that causes homeowners to unknowingly violate By-Law 2006-96 by replacing too much of their front yard grass with interlocking.
What happens if my driveway widening violates Markham's by-law?+
The City of Markham can issue fines and, in more serious cases, mandatory removal orders requiring you to remove non-compliant hardscaping at your own expense. Violations can also create complications when selling your home. This is why Cedarwood measures every property and designs for by-law compliance before any work begins.
Can I add a second parking space in a Cornell or Wismer townhouse?+
Possibly, but it depends on your lot frontage and garage width. Townhouse lots in Cornell and Wismer tend to be narrow (6–8m frontage), which limits total driveway width to 3.0–4.0m under the 50% rule. In some cases, a small side extension is achievable. In others, creative design — like a widened apron or an interlocking landing pad — can improve usability within the legal limits. Cedarwood measures first before making any promises.

We serve all Markham neighbourhoods including Cornell, Greensborough, Wismer, Box Grove, Angus Glen, Berczy Village, Unionville, Cathedral, and Markham Village, as well as Vaughan, Richmond Hill, Ajax, Pickering, Whitby, Toronto, Mississauga, and the entire GTA.
