Hello, I’m having a disagreement with my contractor that I’m hoping you can settle. He’s building a new set of stairs off my deck for which I already poured a concrete pad. He says it’s in the wrong spot but he is taking the rise measurement straight down from the top of the deck and I took my measurement from the stair landing. It’s a full 10inch difference in height. I am a girl and not a contractor but his measurement doesn’t make sense to me. Who is taking the correct measurement here?
