Not in the county I live in. People here cannot build anything on their property without a permit. I bet if you built a doghouse, it would have to be less than a specific amount of square feet, or you would need a permit...lol... I think it is a state decision and each state has their own guidelines. Even putting up a fence around your property needs a permit in some areas of our county, and then there are specifications on how the "fence" looks and what it is made out of before you can put one up.
