A quality shed adds storage, workspace, and property value to Ottawa homes. Whether you need a garden tool storage shed, a workshop, a home office outbuilding, or a she-shed/man-cave retreat, the options range from basic pre-fab units to fully finished custom buildings. Ottawa's zoning bylaws allow accessory structures (sheds) in most residential zones, but there are important rules about size, placement, and height that determine whether you need a building permit. Understanding these rules be...

Foundation: Never place a shed directly on grass or soil in Ottawa — moisture and frost will destroy it. Options include: compacted gravel pad (cheapest, $200–$500), concrete piers or deck blocks ($300–$600), and poured concrete slab ($1,000–$2,500). For sheds larger than 10x12, concrete piers or slab is recommended. Roofing: Match your shed's shingles to your house for a cohesive look. Use the same brand and colour. Architectural shingles ($40–$60 per bundle) last longer and look better than 3...
Pre-fab metal sheds start at $800. Pre-fab wood kits cost $2,000–$4,000. Custom-built wood sheds cost $4,000–$8,000. Workshop sheds cost $8,000–$15,000. Finished office/studio sheds cost $15,000–$35,000.
Sheds 108 sq ft or smaller with no electrical or plumbing do not require a permit but must comply with setback requirements. Sheds over 108 sq ft or with utilities require a City of Ottawa building permit.
In most Ottawa residential zones, sheds must be at least 1 metre from side and rear property lines. Corner lots have additional setback requirements. Check your specific zoning before building.
A compacted gravel pad works for smaller sheds (under 10x10). Concrete piers or deck blocks are recommended for 10x12 and larger. Poured concrete slabs are the premium option, especially for workshop or finished sheds.
