NIST recommended square footage for forensic laboratories compared with actual facilities: Size matters

Trends in modern forensic laboratory construction reveal a significant increase in square footage per staff member compared to older facilities. This expansion stems from a blend of operational, regulatory, and architectural factors, rather than solely sustainability goals. The growing scientific scope, more rigorous accreditation standards, and the critical need for flexibility and secure evidence handling all contribute to these rising spatial requirements. While high-performance building frameworks like LEED can introduce additional design considerations, particularly for mechanical systems and circulation, sustainability is best understood as one influence among many. This technical note, drawing on Project FORESIGHT benchmarking data and NIST facility planning guidance, outlines the primary drivers of laboratory size in new construction and offers practical recommendations for facility planners aiming to align space allocation with forensic function.
