Markham’s Fence By-law 2004-203 sets the base rules: 2 m rear/side, 0.9 m front (1.5 m for 50%+ open). What makes Markham unique is the Heritage Conservation District (HCD) that covers much of Main Street Unionville — if your property falls within the HCD, you need a Heritage Permit before any fence work begins, and certain materials and styles may be restricted to maintain streetscape character. We handle the Heritage Permit application as part of scope when applicable.
Markham’s subdivisions each have their own architectural vocabulary. Cornell (neo-traditional, rear-garage urban planning) favours traditional picket. Cathedraltown has gone strongly toward horizontal modern. Box Grove and Berczy (90s–00s suburban) mix composite and cedar depending on the block.
The Rouge National Urban Park runs along Markham’s eastern edge — properties backing onto or adjacent to the park may have TRCA regulated-area overlays. We verify before quoting.
Markham soil is predominantly clay till with frequent fieldstone, similar to Vaughan. Expect 10% of post holes to hit rock that requires extra work. We quote for this — no surprise change orders.
