Rhode Island Building Code
Structural calculations in Rhode Island must comply with locally adopted IRC/IBC standards. Span tables, load ratings, and deflection limits vary by species, grade, and spacing — and local amendments in jurisdictions like Providence may impose additional requirements. FieldLab’s span lookup tables match the IRC/IBC reference tables used by code officials.
