San Jose FAQ
Do I need a permit for a paper sale sign in my San Jose store window?
Short-duration paper window signs for promotions are generally exempt from permit requirements if they stay within the percentage cap and are removed after the promotion. Permanent vinyl, neon, or illuminated signs do require a city sign permit.
Can I cover my entire window with vinyl graphics?
No. SJMC Title 23 limits permanent window coverage to roughly 25 percent in most commercial zones to maintain visibility and natural surveillance. Full window-wraps usually require a variance or design review and are often denied in storefront districts.
Are neon Open signs allowed?
Yes, small neon or LED Open signs are allowed but count toward the window coverage cap and the overall tenant sign allowance. Brightness, blinking, and animation are restricted, especially near residential zones and historic districts.
