Summary
Portsmouth allows digital signs with automatic changeable copy in any zoning district except on property used for household or group living. Each message must hold for at least eight seconds, switch in 0.25 seconds or less, and stay under 1,500 nits by day and 150 nits at other times. Full outdoor advertising billboards are confined to IL and IN districts and need a City Council Use Permit.
The luminance of a sign shall not exceed 1,500 nits during daylight hours and 150 nits at all other times. Signs incorporating displays that use light emitting diodes (LEDs), charge coupling devices (CCDs), plasma, or functionally equivalent technologies shall be equipped with automatic dimming technology and certified by the manufacturer or a qualified professional to be compliant with the maximum luminance standards in this subsection (5)(c). ... Signs incorporating automatic changeable copy shall comply with the following standards: (i) The display or copy shall remain static prior to each change for a period of not less than eight seconds. (ii) Each change of the display or copy shall be accomplished within 0.25 seconds or less if the change is affected by digital means, or two seconds if the change is effected by mechanical means. (iii) Each change of the display or copy shall be accomplished without the use of animation, scrolling, or simulated movement. (iv) The device that automatically changes the display or copy shall be designed and equipped to maintain a static display if a malfunction occurs.

Full Breakdown
Section 40.2-307 of the Portsmouth zoning ordinance treats an electronic message display as "automatic changeable copy," defined as the capacity to display words, symbols, figures, or images that can be electronically changed by remote or automatic means. Under subsection (I)(6)(b), these signs are permitted in any zoning district, but not on any property containing a use listed under the Household Living or Group Living subcategories of the Residential Use category in the Use Table (Table 40.2-216). A digital sign on a house, apartment complex, or group home lot is therefore out, while a shop, church, or industrial lot elsewhere in the city can have one.\n\nThe operating standards in (I)(6)(c) are exact.
The display must stay static for no less than eight seconds before each change. A digital change must finish within 0.25 seconds, and a mechanical change within two seconds. No change may use animation, scrolling, or simulated movement, which also matches the citywide ban in (E)(7) on signs that include movement or animation. The device must be built to freeze on a static display if it malfunctions.\n\nBrightness is capped separately in (I)(5)(c): 1,500 nits during daylight hours and 150 nits at all other times. LED, charge coupling device, plasma, or equivalent displays must carry automatic dimming technology, and the manufacturer or a qualified professional must certify that the sign meets those luminance limits.
Illumination also must avoid glare on adjoining properties and any glare that interferes with traffic safety.\n\nA true billboard is a separate category. Portsmouth defines an outdoor advertising sign as a structure with display space for general advertising, and says these signs may carry LED displays that comply with state and federal law. Under (J)(3)(e) they are permitted only in the IL and IN districts after City Council approves a Use Permit under Sec. 40.2-533. Under (H)(2), a new sign, a replacement, or converting an existing billboard to an LED or automatic changeable copy display each requires that Use Permit. Changing sign faces on an existing sign is exempt from the Zoning Permit under (G)(1).
Violations & Fines
Section 40.2-307 prints no separate fine, so a violation is a failure to comply with the zoning ordinance. A sign that changes faster than eight seconds, scrolls, exceeds the nit limits, lacks certified dimming, or sits on a household or group living property does not conform. Converting a billboard to LED without the required City Council Use Permit is an unpermitted modification under (H)(2)(c). Digital signs along interstate or federal aid primary highways also need Virginia Department of Transportation approvals.
