My stairs will come straight off my house, with no deck. Can the upper rail be attached straight to the house with the bracket that is supplied?

Hello jcbil, thank you for reaching out to us. We would usually recommend the rail to start and stop on a post. The screw we provide to attach the rails at a post are wood screws, wood screws may not work for attaching directly to your house. In this situation, we would suggest reaching out to a code official on how to make this work for attachment at the house instead of a post. Kindly, - Trex Customer Care Team
