Bring the supporting structure into the first discussion.
Cedar Park publishes deck and patio-cover checklists within its residential permit resources. A composite finish is one part of the project. The supporting frame, height above grade, attachment, stairs and transitions need to be defined before a surface-only price can represent the full scope.
If replacing an existing deck, provide photographs of the framing as well as the boards. Do not assume the old frame is suitable for a new product or layout. For a shared commercial outdoor space, begin with its own review requirements and circulation needs rather than treating a residential checklist as the governing standard.
