Full Breakdown
Indio's Unified Development Code sets a separate standard for freeway-oriented signs facing Interstate 10 in the Regional Commercial and Industrial zones. On parcels of 20 acres or more, a freestanding sign may reach 500 square feet and 55 feet in height (25 feet above freeway grade), spaced at least 500 feet from any other freeway-oriented sign and set back 25 feet from the I-10 right-of-way. Parcels smaller than 20 acres are capped at 300 square feet and 40 feet, with 400 feet of spacing. Only one freeway-oriented sign is allowed per freeway frontage, and a line-of-sight study is required to justify the requested height.
Violations & Fines
Signs exceeding the area, height, or spacing limits, or erected without City sign permit review and the required line-of-sight study, are non-conforming and subject to code enforcement and removal.
