Sign Code

Sign Code

The sign code regulates sign displays to maintain community aesthetic values, ensure individual rights to commercial and noncommercial expression, and minimize effects on traffic safety.

The sign code requires that signs on any building have a City of Boulder sign permit. A licensed sign contractor must obtain a permit and install the sign.
