Seattle SDOT & SDCI Project Signs
Director's Rule 6-2025

Mastering the Large White Notice Sign.

Seattle is the most regulated market in the PNW. If you are building anywhere from Ballard to Rainier Valley, you need to comply with SDCI Director’s Rule 6-2025 (formerly 13-2021). Big Bass Signs is your factory for the mandatory "Large White Project Information Signs."

Seattle Code Essentials

• Land Use Signs: We fabricate the mandatory "Large White Sign" specified in SDCI Director’s Rule 6-2025.  We print the exact "M" (Master Use Permit) or "L" (Land Use) logo, the 3D rendering, and the site map directly onto 4x8 plywood, ensuring full compliance for your specific project number.

• Public Notice Signs: Navigating SDOT requirements? We print the "Street Use Permit" notices and "Sidewalk Closed" signs required for right-of-way impacts. We use high-intensity reflective vinyl on aluminum to ensure these legal notices are visible to drivers and pedestrians alike, day or night.

• Funding Declaration Signs: Seattle projects often involve complex funding stacks. We print the "Seattle Housing Levy," "Move Seattle," or "MFTE" (Multi-Family Tax Exemption) signage. These signs are designed to meet the strict branding standards of the City of Seattle Office of Housing or Seattle Department of Transportation.

• Post-and-Panel Installs: For steep Seattle slopes or busy sidewalks, we provide the heavy-duty 4x4 post kits to ensure your notice signs don't blow over in a winter storm.

High-Density Construction

• High-Rise Highlights: We print hundreds of linear feet of branded fence mesh and solid DiBond panels to secure your site and market the building to passing pedestrians.

These are a few of the services popular for our clients in Seattle, WA, but our whole suite of printing products and installation services are available in Seattle to meet local codes and signage regulations while adding durable and beautiful signs to your site.
