Summary
Auburn bans billboards outright citywide: the large off-premises advertising signs typically aimed at freeway traffic cannot be erected or placed anywhere in the city under the sign code's list of prohibited signs.
I. Prohibited Signs. From and after the effective date of the ordinance codified in this chapter it shall be unlawful for any person to erect or place within the city, except as otherwise authorized: ... 13. Billboards;

Full Breakdown
020(C) as 'a large outdoor advertising sign containing a message, commercial or otherwise, unrelated to the use or activity on the property on which the sign is located and/or to any use or activity in the immediate area,' customarily leased for commercial purposes, with faces ranging roughly 12 to 14 feet in height and 24 to 48 feet in width, the format most associated with freeway-facing advertising. Because billboards fall under the outright prohibition rather than a district-specific size or height allowance, there is no zone in Auburn, including areas along SR 167 or SR 18, where a new billboard can be permitted through the standard sign permit process.
8). 040(E)(5) allows a narrower category of off-premises signs in the C-2 zone up to 20 feet in height and within 750 feet of the advertised business, which is a distinctly different, smaller instrument than a billboard.
Violations & Fines
Erecting a billboard anywhere in Auburn, or any large freeway-oriented off-premises sign meeting the billboard definition in ACC 18.56.020(C), violates the prohibition in ACC 18.56.030(I)(13); the building official can deny the permit application outright and pursue removal through the city's code compliance process.
