Sign Plan & Submission Notes for Algonquin
- Common Signage Plan (definition provided in Section 29.02) is required in the Randall Road Corridor District for zoning lots with multiple uses or multiple users; it must: limit freestanding signs to one per street frontage, provide shared/common use of the main freestanding sign, be included in any PUD plan or other official plans required by the Village, and no sign may be erected except in conformance with the approved plan (Section 29.14-D).
- In the Old Town District, where multiple principal establishments in a building seek projecting signs, a common signage plan is strongly encouraged (Section 29.13-F-1.viii).
- Planned Unit Developments (PUD): The Village may permit additional or different signage, or require different signage standards, as part of final PUD approval (Section 29.05-D; see also Section 29.14-C for special areas of control).
- Special Areas of Control: The Village Board may designate geographic areas with unique characteristics as special areas of control with distinct sign standards, administered via mapped areas and dedicated code sections (Section 29.05-C; e.g., Old Town District Section 29.13 and Randall Road Corridor Section 29.14).
- Permits: Unless exempt, all signs require a sign permit; illuminated signs also require an electrical permit (Section 29.16-A.1 and A.4). Erecting, altering, or relocating a sign without a required permit results in doubled permit fees and does not waive penalties (Section 29.16-D.3).
- Variations: If code standards preclude a proposed sign, an applicant may request a variation; this requires a public meeting before the Village Board (following Committee of the Whole recommendations), payment of a Variation Review Fee, and the Board may impose conditions; the variation becomes void if not acted upon within 6 months by issuance of a valid sign permit (Section 29.18-A). Appeals of interpretations are heard by the Planning and Zoning Commission (Section 29.18-B).
