As far as I'm aware, the datasources or data sets is extremely sparse and concentrate to particular geographies, not entirely the US. However, these two websites I came across can assist you in finding out more about your data:

  • I couldn't find any data on these ws. I guess this type of data isn't available yet. What about private land ownership?? where can I retrieve this kind of data for free?? – Isma Il May 30 '17 at 21:29
  • billboardmap.usc.edu/Services/Billboards/Default.aspx has some sparse data, your options are limited unless you do field work (time consuming) to get the data raw. – Mapperz May 31 '17 at 1:25
