About 15 months ago, I purchased a home from a builder (spec. home). Overall, the quality of his work and follow-up were quite poor. In fact, he has not completed the escrow work or warranty work. This past weekend, I was at a trade show, and the builder had an exhibit. The exhibit featured a number of photos taken of my house. I was quite surprised to see these photos which clearly he had taken in the past week. Is this legal without my permission? Thank you for your advice.What is the name of your state (only U.S. law)?
