Summary
Digital dynamic-display signs are barred citywide except in Downtown districts, the Transit Oriented Development and Connecticut River overlays, schools, and specific authorized billboards, and always require a special permit under Hartford's zoning code.
A.Permitted Districts. Dynamic displays are permitted only within the DT districts, the Transit Oriented Development Overlay, the Connecticut River Overlay, and lots containing School: Pre-K, Primary, Elementary, Intermediate, or School: High School, or on existing or new billboards expressly authorized in 8.12.3 D.B.Special Permit. An approved Special Permit (refer to 1.3.4) is required for installation of any sign with a dynamic display.
Full Breakdown
Section 8.12.3 confines dynamic (digital) displays to the DT districts, the Transit Oriented Development Overlay, the Connecticut River Overlay, school properties, and billboards separately authorized under 8.12.3 D. Every dynamic display needs an approved special permit regardless of district. Once installed, each message must hold for at least 8 seconds with no animation, video, or special effects, and transitions between messages must take one second or less. Brightness is capped at 5,000 nits by day and 250 nits between a half-hour after sunset and a half-hour before sunrise, enforced with a photocell and manufacturer certification before any sign permit issues.
Violations & Fines
A dynamic display measured above the 5,000/250-nit brightness caps must be adjusted downward or faces further zoning enforcement; a display installed outside the permitted districts or without a special permit is an unauthorized sign under § 8.12.3.
