Do You Need a Permit to Tear Down a Shed or Deck in Kitsap County?

Kitsap County's Department of Community Development publishes a straightforward reference for this exact question, and the thresholds are more specific than most homeowners expect.

Sheds: The 200 Square Foot Line

A one-story detached accessory structure, the kind most backyard sheds fall under, generally doesn't need a building permit if its footprint stays under 200 square feet. Cross that line and a permit typically applies. This matches the pattern in most Washington counties, though the exact number varies by jurisdiction, some cities use 120 square feet instead.

Decks: Height Matters as Much as Size

Decks are a bit more layered. A deck is commonly exempt from a permit when it stays under 200 square feet AND sits no more than 30 inches above grade at any point. A deck that's larger, taller, attached in a way that serves as a required exit, or built onto a shoreline property often needs a permit regardless of size.

Demolition Isn't Automatically Exempt Just Because Building Was

Here's the detail that catches people off guard: even a permit-exempt structure can involve different rules when it's being demolished as part of a larger project, or when the original structure never had proper permitting in the first place. If a deck or shed was previously permitted, or would have required a permit when built, its removal is sometimes treated as its own permit item.

What This Means If You're Just Trying to Get Rid of an Old Structure

For a small, permit-exempt shed or a low deck under the threshold, tear-down and haul-away can usually happen the same way any other demolition job does, no county paperwork involved. For anything larger, or if you're unsure which category yours falls into, a quick call to Kitsap County's Department of Community Development settles it before any work starts.
