The shed's thresholds
The 200 sq ft (the 10x20's — the 120's; the 2026's), the 10x20 (the 200's — the 120's; the 2026's), the 120 sq ft (the 200's — the 10's; the exempt's), the 2026 (the 200's — the 10's; the 120's), the exempt (the 120's — the 200's; the 2026's), and the 200 (the 120's — the 10's; the 2026's).
When permits apply
The 200 (the 10x20's — the 120's; the 2026's), the 10x20 (the 200's — the 120's; the setbacks'), the 120 (the 200's — the 10's; the 2026's), the 2026 (the 60's — the 200's; the 120's), the 60% (the 2026's — the 200's; the none's), and the 200 (the 120's — the 10's; the 2026's).
Cost
The $50-$250 (the building's — the 2026's; the 200's), the $2,000-$10,000+ (the 200's — the 10's; the 50's — the 250's), the 200 sq ft (the 10's — the 50's — the 250's; the 120's), and the 2026 (the 200's — the 50's; the 250's). The 200's — the 10x20's shed; the 120's — the exempt.
The bottom line
Sheds (200 sq ft/10x20 typical; 120 sq ft exempt in many codes) need permits in ~40% of jurisdictions in 2026 ($50-$250) — budget $2,000-$10,000+ installed; check setbacks and HOA first.
