Glendale FAQ
Can I convert my static billboard to digital in unincorporated Maricopa?
Possibly. You need ADOT permit amendment plus county zoning approval. Many city jurisdictions limit conversions to one new digital per several static faces removed under cap-and-trade billboard policies.
How fast can the message rotate on an Arizona digital billboard?
Each message must hold static at least 8 seconds with the transition under 1 second per ADOT rules and ARS 28-7732. Faster animation is treated as moving signage, which is prohibited.
Phoenix FAQ
Can I put a digital billboard on my Phoenix commercial property?
Only in designated overlay corridors and only by converting an existing legal billboard elsewhere under the takedown ratio. New off-premise billboards are not allowed in most of Phoenix.
What about digital signs on my own business?
On-premise digital signs face separate rules in Section 36-49 with size, brightness, and dwell-time limits but are allowed in commercial and industrial zones. Residential zones generally prohibit them.
