Summary

Electronic billboards in Boise must show static frames only, changing no more than once every 8 seconds, with strict brightness caps.

Electronic message displays are allowed with static frame effects that change with no transition - no more frequently than every 8 seconds. Brightness levels shall comply with Section 11-04-012.7.A(5)(b)vi. A change from non-EMD to EMD requires the approval of a sign permit.

Full Breakdown

Boise caps the number of billboards citywide, no new ones except through annexation, and treats electronic message displays on billboards as a Conditional Use Permit matter in the MX-2, MX-3, I-1, and I-2 districts only. Electronic message displays on billboards are allowed only with static frame effects that change with no transition, no more frequently than every 8 seconds, and brightness must comply with the citywide EMD brightness standard. Converting an existing static billboard to an electronic display requires a new sign permit.

Violations & Fines

Planning and Development Services enforces the Development Code; installing or operating an EMD billboard without the required Conditional Use Permit and sign permit, or violating frame-change or brightness limits, is a code violation subject to standard zoning enforcement and potential permit revocation.

Frequently Asked Questions

Can a new digital billboard be built anywhere in Boise?
No. Off-premise billboards are limited to the MX-2, MX-3, I-1, and I-2 zoning districts, need a Conditional Use Permit, and the citywide billboard count cannot increase except through annexation.
Can an existing static billboard be converted to digital?
Yes, but only with a new sign permit, and the display must use static frame effects changing no more than every 8 seconds, per Boise City Code § 11-04-012.
