Adco Outdoor Advertising

ADCO Outdoor is a California billboard company and out-of-home media owner that has operated since 1963. Based in Belmont, California, the company maintains advertising structures across both northern and southern California, with a concentration of inventory in the San Francisco Bay Area and Silicon Valley along with markets reaching toward Sacramento and Lake Tahoe, the Sonoma and Napa wine country, the Gilroy and Monterey corridor, and the Vallejo and Fairfield area. ADCO offers a range of formats, including static outdoor billboards in sizes from smaller panels up to large bulletins exceeding eighteen by forty-eight feet, digital billboards that rotate multiple advertisers, illuminated and non-illuminated displays, and wallscapes.

Its structures are positioned along heavily trafficked routes such as Highway 101, Interstate 80, and the Bayshore Freeway, targeting commuters and travelers, with weekly impression counts that the company says range from the tens of thousands to more than nine hundred thousand depending on location. ADCO markets itself as a full-service provider, supporting advertisers through the design, planning, and launch of outdoor campaigns and offering custom creative design services in addition to media placement. The company serves both local businesses and national brands seeking exposure in California's dense and high-value markets.

With more than six decades of operating history and an owned plant spanning multiple regions of the state, ADCO positions itself as an experienced independent operator able to build multi-market billboard campaigns across California while providing direct, hands-on client service from its Belmont base near the San Francisco Peninsula.
