Accessory structures are a growing outdoor renovation category in the GTA. This thread covers 2026 permit requirements and costs for sheds, pergolas, and gazebos.

**Shed Permit Requirements**  
City of Toronto: sheds under 10 sq m (108 sq ft) with no plumbing or electrical - no permit required. Over 10 sq m: permit required. Setback requirements (typically 1.2-1.8m from lot lines) apply regardless. Most GTA municipalities follow similar thresholds.

**Pergola and Gazebo Permits**  
Freestanding pergola under 10 sq m: typically no permit. Attached pergola (attached to house): treated as addition, permit required. Gazebo with roofing: permit required in most GTA municipalities. Verify with local building department before construction.

**Costs**  
Prefab storage shed (10x12, installed): $3,000-$8,000. Custom-built shed: $6,000-$18,000. Cedar pergola (12x16 ft, freestanding): $4,000-$10,000. Aluminum pergola with adjustable louvres: $8,000-$20,000.
