Common Questions

In 2026, the City of Windsor charges a minimum permit fee of $250.00 plus a non-refundable $70.00 Zoning Certificate fee for small residential projects like decks, totaling at least $320.00.

For 2026, composite decking (such as Trex or TimberTech) typically costs between $65 and $95 per square foot installed, compared to $45 to $65 for pressure-treated wood.

A building permit is generally required if the deck is more than 24 inches (600 mm) above the adjacent grade. However, even for decks under this height, a $70.00 zoning certificate is often required to ensure compliance with property setbacks.

Professional deck contractors in the Windsor-Essex region typically charge between $25 and $50 per square foot for labor, while the average hourly rate for a construction laborer is approximately $35.00 CAD.
