Do I need a permit to pour a concrete pad for a backyard shed in Fredericton?

For most backyard shed pads in Fredericton, you won't need a permit as long as the shed itself is under 108 square feet and meets setback requirements. However, you should confirm with the City of Fredericton building department since regulations can vary based on your specific property zoning and the shed's intended use.

Fredericton's typical shed regulations allow structures under 108 square feet (roughly 10x10 feet) without a building permit, provided they're used for storage only and meet property line setbacks — usually 3-5 feet from side and rear property lines. The concrete pad itself doesn't typically require a separate permit when it's supporting a permitted accessory structure. However, if your shed exceeds 108 square feet, requires electrical service, or will be used as a workshop or living space, both the shed and foundation may require permits.

Even without a permit, your concrete pad must still be built properly for New Brunswick's climate. The pad should be 4-5 inches thick with a proper gravel base, and the concrete must extend below the frost line if it's a structural foundation. For a simple shed pad that sits on grade, you'll want 4-6 inches of compacted gravel base topped with 4 inches of air-entrained concrete. The frost line in Fredericton is 4 feet deep, but most shed pads are designed as floating slabs that can handle minor frost movement.

Property line setbacks are crucial — even if no permit is required, violating setback requirements can force you to relocate or remove the structure later. Check your property survey and measure carefully. Some neighborhoods have additional covenant restrictions beyond city bylaws. If your property backs onto a stream, wetland, or environmentally sensitive area, additional restrictions may apply.

When to contact the city: Call Fredericton's building inspection department at (506) 460-2020 if your shed will exceed 108 square feet, if you're unsure about setback requirements, or if your property has unique zoning. They can confirm whether your specific project requires permits and provide the exact setback requirements for your zone. It's a quick call that can save you from costly mistakes later.

For the concrete work itself, a typical 10x12 foot shed pad runs $800-$1,500 depending on site access and base preparation requirements. The optimal timing for pouring in Fredericton is May through October when temperatures stay consistently above 10°C for proper curing.
