Fire Sprinkler Permitting
Every fire sprinkler system in Washington state needs a permit before installation can start. Each city has its own building department, its own application process, and its own plan review timeline. We handle all of it.
Rain City Fire Protection prepares complete permit packages and submits them directly to your local building department. We track the review, respond to comments, and keep your project on schedule.

How the Permit Process Works
1. Design Completion
Once the sprinkler design is finalized (either by us or a third-party engineer), we compile the complete permit package — drawings, calculations, specifications, and application forms.
2. Submission
We submit the package to the appropriate building department. For Seattle projects, that’s SDCI. For Eastside projects, it’s the city where the home is being built. Most jurisdictions accept electronic submissions.
3. Plan Review
The building department reviews the drawings for code compliance. If they have comments or requests for changes, we handle the revisions and resubmit. You don’t need to be involved in this back-and-forth.
4. Permit Issued
Once approved, we pick up the permit and coordinate with your builder to schedule installation. The approved drawings become the field installation guide.
Frequently Asked Questions
Permit fees vary by jurisdiction. Seattle (SDCI) fees are typically higher than Eastside cities. Fees are usually based on project valuation or a flat rate for residential sprinkler systems. We'll let you know the exact fee for your jurisdiction before we submit.
Seattle (SDCI) typically takes 2 to 3 weeks for plan review. Most Eastside cities — Bellevue, Kirkland, Redmond, Issaquah — run 1 to 2 weeks. These timelines can shift during busy seasons. We track your application and follow up with the building department if there are delays.
We do. We prepare the complete permit package — drawings, calculations, application forms — and submit it to the building department on your behalf. You don't need to visit any city offices or fill out paperwork.
Plan review comments are normal. If the building department requests changes, we revise the drawings and resubmit at no additional charge. Most revision cycles add only a few days to the timeline.
Yes. If you have an existing NFPA 13D design from another engineer, we can review it and submit the permit package. We'll flag anything that might cause issues during plan review before we submit.
