Permit rules for garage door replacement vary by city and county in Washington, and the answer isn't the same everywhere — which is exactly why it's worth checking before assuming either way.
The general pattern
Most Washington jurisdictions do not require a permit for a straightforward like-for-like replacement — same size opening, same basic door type, no structural changes. Many building departments treat this as routine maintenance rather than construction.
When a permit is more likely to be required
- You're changing the size of the opening (widening, heightening, or converting two singles to one double)
- You're adding significant structural changes to the framing or header
- New electrical work is involved (a dedicated circuit for a smart opener, for example)
- Your home is in a jurisdiction with stricter rules than the state baseline — city and county requirements differ
- You're in an HOA-governed community, which may require design approval separate from any city permit
Who's responsible for pulling the permit
On a standard replacement where a permit is required, the installing company typically handles the permit application as part of the job — worth confirming this explicitly before work starts, so it isn't assumed to be your responsibility after the fact.
