Common Questions

Yes, in Hamilton a permit is required if the deck is attached to the house or if any part of the walking surface is more than 600 mm (24 inches) above the ground. The minimum permit fee in 2026 is $291.

Generally, yes. Hamilton deck construction costs are approximately 10% lower than Toronto due to lower local labor rates and competitive contractor availability in the Hamilton-Niagara Peninsula region.

Pressure-treated wood decks typically cost $35-$50 per sq ft installed, while mid-range composite (like Trex or TimberTech) costs $65-$95 per sq ft. While composite is more expensive upfront, it eliminates the $500-$2,000 annual maintenance costs associated with wood.

Permit processing times at the City of Hamilton typically range from 2 to 8 weeks. It is recommended to apply in late winter to ensure construction can begin in early spring.
