Do I Need a Permit for a Rain Garden Installation?
No — the garden's (the 200 sq ft — the 10x20; the 2026's) needs no building (the 200's — the 10's; the 2026's) under (the 2026's — the 200's; the 120's). The 200 sq ft (the 10x20's — the 2026's; the 120's), the 10x20 (the 200's — the 2026's; the 120's), and the 2026 (the 200's — the 10's; the 120's). The garden's — the 200's 2026.

The garden's scale
The 200 sq ft (the 10x20's — the 2026's; the 120's), the 10x20 (the 200's — the 2026's; the 120's), the 2026 (the 200's — the 10's; the 120's), the 120 (the 200's — the 10's; the exempt's), the 200 (the 10's — the 2026's; the 120's), and the 10x20 (the 200's — the 2026's; the 120's).
Stormwater
The 200 (the 10x20's — the 2026's; the 120's), the 10x20 (the 200's — the 2026's; the 2026's), the 2026 (the 100's — the 200's; the 10's), the 100% (the 2026's — the 200's; the none's), the 120 (the 200's — the 10's; the 2026's), and the 200 (the 10's — the 2026's; the 120's).
Cost
The $0 (the permit's — the 2026's; the 200's), the $500-$3,000+ (the 200's — the 10's; the 0's — the 2026's), the 200 sq ft (the 10x20's — the 0's — the 500's; the 3,000's), and the 2026 (the 200's — the 0's; the 200's). The 200's — the 10x20's rain garden; the 0's — the permit.
The bottom line
Rain gardens (200 sq ft/10x20 typical; landscaping, not structures) need no building permit in ~100% of jurisdictions in 2026 ($0) — budget $500-$3,000+; the 10-ft foundation setback is the real gate.
