To adequately show that at least 45% of regularly occupied spaces comply with vision requirements, you’ll have to provide documentation showing line of sight for the spaces that are contributing to credit achievement, even if floor plans and cubical configurations vary throughout the building. If this is particularly onerous for your building, consider providing section plans for a representative sample of layouts and explaining the percent of regularly occupied spaces that these samples represent. The key here is to provide clear, accurate documentation for as many spaces as possible to support your claims and show that you’re doing the assessment correctly.
