Do I Need a Permit for a Chicken Coop Installation?
Rarely — the coop's (the 100 sq ft — the 10x10; the 120's) usually needs no building (the 100's — the 10's; the 120's) under (the 120's — the 100's; the 2026's). The 100 (the 10x10's — the 120's; the 2026's), the 10x10 (the 100's — the 120's; the 2026's), and the 120 (the 100's — the 10's; the 2026's). The coop's — the 100's zoning.

The coop's thresholds
The 100 sq ft (the 10x10's — the 120's; the 2026's), the 10x10 (the 100's — the 120's; the 2026's), the 120 sq ft (the 100's — the 10's; the exempt's), the 2026 (the 100's — the 10's; the 120's), the 6-hen (the 100's — the 10's; the 2026's), and the 100 (the 120's — the 10's; the 2026's).
When rules apply
The 100 (the 10x10's — the 120's; the 2026's), the 10x10 (the 100's — the 120's; the setbacks'), the 120 (the 100's — the 10's; the 2026's), the 2026 (the 80's — the 100's; the 120's), the 80% (the 2026's — the 100's; the none's), and the 100 (the 120's — the 10's; the 2026's).
Cost
The $0-$100 (the zoning's — the 2026's; the 100's), the $500-$3,000+ (the 100's — the 10's; the 0's — the 100's), the 100 sq ft (the 10's — the 0's — the 100's; the 120's), and the 2026 (the 100's — the 0's; the 100's). The 100's — the 10x10's coop; the 120's — the exempt.
The bottom line
Chicken coops (100 sq ft/10x10 typical; under the 120 sq ft exempt threshold) need building permits in only ~20% of jurisdictions in 2026 ($0-$100) — budget $500-$3,000+; the 6-hen zoning limit and setbacks are the real gates.
