Can i build a floating deck under 2 feet off the ground in Riverview without getting a building permit?

Yes, you can likely build a floating deck under 2 feet high in Riverview without a building permit, but you'll want to confirm the specific height threshold with the Town of Riverview first.

Most New Brunswick municipalities follow the National Building Code exemption for decks under 24 inches (2 feet) in height, and floating decks (not attached to the house) are generally treated more leniently than attached structures. However, each municipality can set their own thresholds in their building bylaws.

What qualifies as permit-exempt typically includes decks that are:

• Under 24 inches above grade at any point


• Not attached to the house structure


• Under a certain square footage (often 108 sq ft or 10m²)


• Not over a basement or crawl space

The Town of Riverview's Development Services department can give you the definitive answer on their specific requirements. Even if a permit isn't required, your deck still needs to meet setback requirements from property lines — typically 3-6 feet depending on your lot size and zoning. These setback rules are found in Riverview's zoning bylaw and can result in fines if violated.

Consider these practical factors for your floating deck project: Riverview's clay soils and high water table mean proper drainage is crucial. Use concrete deck blocks or treated lumber footings on a gravel base to prevent settling. With New Brunswick's freeze-thaw cycles, ensure your footings extend below the frost line (about 4 feet) if you're using permanent concrete piers, or use adjustable deck blocks that can accommodate seasonal movement.

Your next step: Call Riverview's Development Services to confirm their exact deck permit thresholds and setback requirements for your specific property. Even a quick 5-minute call can save you potential headaches down the road.
