Deck permits

Check whether you need a permit

A building permit is required in Milton if your deck is:

• a freestanding deck greater than 10 m² (≈ 108 sq ft) in area
• attached to a building or structure

Check the zoning regulations

Before building your deck, review the Zoning By-law to ensure your project complies with all applicable requirements. This includes regulations related to:

• Deck height
• Privacy screening
• Deck location and setbacks
• Stairs
• Meeting zoning requirements before applying can help prevent delays during the permit review process.
