I'm planning on building a 45' long retaining wall. My local Home Depot tells me that as long as the wall is under three feet, I can build it without a permit. The stone that I want to use is Anchor Windsor Stone=AE but both the website and the brochure indicate that I can only make this wall 24" high--not three feet. So who's right? Bottom line is that I need to make it as high as I can without a permit but 24" is too low for my project.
Thanks.
