R3-2015 R3 Residential Plansiner The R3-2015 credential focuses exclusively on residential plan review and code compliance—a narrower scope than general construction inspector certifications. While ICC B1 inspectors handle multiple building systems, R3 specialists develop deep expertise in residential framing, MEP coordination, and local amendments. This focused track appeals to reviewers who want mastery without broader construction administration responsibilities.
