Why Silicon Valley Demands a Regional Sign Shop, Not a City Specialist
Silicon Valley isn't one city — it's a chain of adjacent municipalities each with its own sign code, planning counter, and review timeline. A project that spans Sunnyvale and Santa Clara crosses two permit jurisdictions with different dimensional limits, different illumination rules, and different inspection schedules. A brand rollout across San Jose, Mountain View, and Cupertino requires consistent fabrication delivered to three different code environments. Business signs Silicon Valley companies deploy fail when they're designed for one city and forced onto another. They succeed when the shop reads every code and engineers for each one.
- 10+ separate permit jurisdictions — San Jose, Santa Clara, Sunnyvale, Mountain View, Cupertino, Palo Alto, Los Altos, Campbell, Milpitas, Saratoga — each with its own planning department and sign ordinance
- Campus brand guidelines that exceed municipal code — Fortune 500 headquarters across the Valley enforce corporate design standards for signage appearance, material, and illumination that city permits don't address
- El Camino Real and Stevens Creek corridors — 45-mph commercial strips where

Los Angeles, CAProfessional, communicative, and efficient! Reasonable prices as well. They met a really important deadline with ease, and I'm so appreciative!
I really enjoyed working with them and would do it again in a heartbeat.
Daniel L.
San Francisco, CAWe had great experience with Martin Sign Company and will use them again. We worked with Sam, and he was friendly and responsive. We love our new signs!
Camille S.
San Francisco, CAThis review is a little overdue. I opened my new business on March 18. I transformed my children's shop of almost 10 years into a beauty boutique. I stayed in my location so I wanted new signage to reflect my new look and overall design. I got quotes back from the manager Jesse in a timely manner and my installer was awesome. Very meticulous and friendly. My new sign looks beautiful, very classy!
