The documents provided discuss fall protection requirements in construction, particularly concerning walking/working surfaces, leading edges, and roofing work 2, 4. Fall protection is generally required for employees working 6 feet (1.8 m) or more above a lower level [1]. Acceptable methods include guardrail systems, safety net systems, or personal fall arrest systems [1]. For roofing work on low-slope roofs, a combination of warning line systems and other methods like guardrail or safety monitoring systems may be used [2].

However, the documents do not specifically address whether the Division of State Architect (DSA) requires fall protection to be installed on new buildings at the roof. Therefore, I cannot provide a definitive answer to your question based on the provided documents.
