Allowing contractors' signs in their yards can save homeowners money - The Denver Post: "Ever wondered how much of a discount your neighbor is getting from his roofer by allowing him to put a sign advertising the company on the front lawn for months on end?
Turns out it can be significant. Then again, sometimes there's nothing in it for the owner except a fight with the homeowners association."
Why yes, of course. The entire neighborhood would turn into Tobacco Road if home owners were allowed to have signs showing who they hired to improve their property.
