Summary
Lehi allows zero new billboards anywhere in the City: Section 23.110.C bans permits for new construction outright. Existing off-premises signs can convert to electronic displays only inside the Off-Premises Electronic Display Sign Overlay Zone, capped at 675 square feet, and only with a conditional-use permit from the Planning Commission.

A nonconforming off-premises sign or billboard may be replaced at the same location with a new sign structure or may be converted to include an electronic display sign pursuant to the provisions of this chapter, provided that the new sign, sign structure, or EDS does not exceed the square footage of the sign face or sign structure being replaced., unless otherwise allowed by that Utah Code Annotated. c.

Full Breakdown
Lehi's Development Code treats billboards as a closed category. C states flatly that no new permits shall be issued for the construction of billboards, leaving every billboard standing in the City classified as a nonconforming use. The only path to a digital billboard is converting one of those existing, legally nonconforming structures. 030, and only if the converted structure keeps the same height and footprint as the sign it replaces; the electronic face itself is capped at 675 square feet of total signage area no matter how large the original structure was.
A converted billboard's message can change no more than once every eight seconds, and the transition itself must complete in a quarter-second or less; the copy must otherwise stay static and complete within itself. Spacing rules keep converted EDS billboards at least 1,000 feet apart along the same side of Interstate 15, shrinking to 750 feet if the owner tears down two square feet of old billboard for every square foot of new electronic sign. Every conversion still requires a conditional use permit reviewed under Chapter 9 of the Development Code, plus a decorative base concealing the support poles and registration in an emergency alert program capable of displaying AMBER Alerts.
Violations & Fines
Any billboard erected without the required conditional use permit, or any conversion that exceeds the 675-square-foot cap or sits outside the mapped Overlay Zone, is an illegal sign under Chapter 23. Any Development Code violation is also a class C misdemeanor under Section 34.010.D, with each ten-day period of continued noncompliance charged as a separate offense, and approvals can be reconsidered or revoked under Section 34.040.
