Many in the residential construction industry believe that fall protection for workers adds unacceptable costs to the job. Some suggest providing fall protection could cost $5,000 or more per structure, but this is an arbitrary number that the authors’ research and real-world experience could not reconcile. Another prevailing idea is that fall protection always requires modifying and reinforcing structures prior to use, which requires the services of an engineer who must also validate and certify the fall protection system. Others have voiced concerns that there is not enough ground clearance on typical single-family structures for workers to use fall arrest systems
