What We Handle

Comprehensive Sign Permitting Services

Different cities in Washington have different rules for sign height, lighting, and placement. We’ve worked across the state — Seattle, Tacoma, Bellevue, Olympia, Everett, Spokane, Vancouver, and Yakima — and we own every step from code research through close-out.

01

Code Research & Compliance

We analyze local sign codes and zoning ordinances for your specific site — ensuring your design meets every requirement before submission.

02

Design Drawings & Specs

Detailed permit-ready drawings with dimensions, materials, illumination type, and mounting details — exactly what the city needs to approve.

03

Engineering Coordination

We coordinate structural and electrical engineering for wind-load calculations, footing specs, and UL-listed electrical connections.

04

Application & Submission

We prepare and submit complete permit packages — reducing back-and-forth with planning departments and avoiding common rejection reasons.

05

City Coordination & Tracking

Direct communication with planning departments throughout the review process, with permit tracking and proactive follow-up.

06

Inspection & Close-Out

We coordinate final inspections with the city after installation — ensuring your sign is fully permitted and compliant from day one.

Local Expertise

We Speak “Sign Code” for Every City in Washington

Each jurisdiction interprets signage differently — and we know the nuances that keep projects moving smoothly. Click any city to see how that department’s review process works.

Our familiarity with local codes prevents costly redesigns and delays — saving you time and money.

Frequently Asked

About Sign Permitting in Washington

How long does a sign permit take in Washington?
It depends on the jurisdiction and the sign type. Straightforward wall signs in cities like Tacoma or Bellevue often clear review in two to four weeks. Seattle SDCI submittals, design-review-overlay districts, freeway-visible signs, and pylon or monument signs with structural footings can run six to twelve weeks. The single biggest schedule risk is rework triggered by an incomplete first submittal — which is exactly what our code-research and pre-submittal review steps are built to prevent.
Do I need a permit for a wall sign in Washington?
In nearly every Washington jurisdiction, yes — permanent exterior wall signs require both a sign permit and, if illuminated, a separate electrical permit. Some cities exempt very small non-illuminated signs (typically under a few square feet) or temporary signage with strict time limits, but exemptions vary by jurisdiction. We handle the code lookup up-front so there’s no surprise after fabrication has started.
What is SDCI?
SDCI is the Seattle Department of Construction & Inspections — the agency that reviews and issues sign permits inside city limits. Seattle is more involved than most Washington cities because sign permits often require an integrated electrical permit, design review for signs in historic districts or shoreline zones, and engineering review for any sign with a structural footing. Plumb Signs maintains an active permitting relationship with SDCI.
Does my sign need a structural engineering stamp?
Free-standing signs — pylons, monuments, multi-tenant cabinets on posts — almost always require a stamped structural engineering package covering wind load, dead load, and footing size. Smaller wall-mounted signs typically don’t, unless they exceed area or projection limits. We produce shop drawings in-house and coordinate the structural stamp with our licensed engineer of record so the permit packet ships complete.
What is the difference between a sign permit and an electrical permit?
A sign permit covers the sign itself — what it looks like, where it sits, and whether it meets the local code for size, height, and placement. An electrical permit covers the wiring, transformer, disconnect, and grounding for any illuminated sign. Some Washington cities (notably Seattle) bundle the two; others issue them separately. Either way, our submittal includes both so nothing gets installed without the right paperwork.
Can Plumb Signs pull permits in cities outside Tacoma?
Yes. Plumb Signs is headquartered in Tacoma and pulls sign permits across Washington — Seattle, Bellevue, Olympia, Everett, Spokane, Vancouver, Yakima, Bremerton, Bellingham, and dozens of smaller jurisdictions. For multi-site rollouts (banks, healthcare systems, retail chains) we coordinate parallel submittals across every city in the program from a single project manager.
What happens if my sign was installed without a permit?
An unpermitted sign typically triggers a stop-work or removal order from code enforcement, and the property owner is on the hook for retroactive permitting fees, fines, and sometimes engineering work to validate the existing installation. We routinely help property owners and tenants get unpermitted signs into compliance — including the as-built drawings, engineering stamp, and city follow-through to close the violation.
How much does sign permitting cost in Washington?
Permitting fees are set by each city and vary with sign type, valuation, and whether structural or electrical review is required. Simple wall-sign permits run a few hundred dollars; complex pylon or freeway-visible programs with structural review can run into the low thousands per jurisdiction. We quote a single program price that covers our code research, drawings, engineering coordination, application prep, follow-through, and final inspection close-out, so there’s no surprise after the city issues its invoice.
