Common Questions

Yes, a permit is required if the deck is attached to the house or if any part of the walking surface is more than 24 inches (600 mm) above the ground. In 2026, Hamilton permit fees for residential decks typically range from $200 to $400.

Pressure-treated wood starts at approximately $25 per sq ft installed. Mid-to-high-end composite (like Trex or TimberTech) ranges from $45 to $85 per sq ft. For a standard 250 sq ft deck, this is a price gap of roughly $6,250 vs $15,000+.

Labor rates for 2026 in the Hamilton area are currently between $12 and $28 per sq ft, depending on the complexity of the design and the material being handled (composite requires more specialized tools and time).

Homeowners should budget an extra $1,000 to $3,000 for 'hidden' items such as helical pile footings (often required for Hamilton's clay soil to prevent frost heave), railing upgrades ($40-$80 per linear ft), and landscape restoration.
