The Prescriptive Residential Wood Deck Construction Guide includes maximum joist spans for Southern Pine and other common framing wood species, and allows for optional overhangs as illustrated in several joist span figures.

For simple span, uniformly distributed load applications without overhangs, please refer to SFPA’s span tables for wet-service floor joists; Tables 12, 13 and 14 are available here. For a complete listing of all span tables, refer to the SFPA publication Southern Pine Maximum Spans for Joists and Rafters.

Make sure that spans for visually graded Southern Pine dimension lumber are based on New Design Values effective June 1, 2013.
