Overview of Permitting Requirements

The City of Chicago requires permits for most new permanent signs, major repairs, and changes to sign faces that affect structure or electrical work. Requirements vary by zoning district, sign type (wall, projecting, canopy, freestanding), and whether electrical connections are involved. Typical requirements include scaled drawings, structural calculations for anchored signs, and proof of property authorization.

Always verify zoning allowances before buying or fabricating a sign.
