Downtown Duncanville DistrictIn the DD district, the Zoning Ordinance (Sec. 4.11.L, Table 4.11.2) sets which sign types are allowed by frontage type and adds its own limits; the Sign Control Board can approve unique sign standards there. Check the lot's frontage type with the city.
Sign Control BoardVariances from Chapter 16A are decided by the Sign Control Board, subject to City Council review (Sec. 16A-6).
Electrical sign contractorsThe city says contractors erecting internally illuminated signs must be registered as Electrical Sign Contractors.
