What Iowa's own rule says
Scaffolding is adopted federal text in Iowa through the construction chapter, which now sits at 481—Chapter 211 rather than 875—Chapter 26. The ten-foot fall-protection trigger, the competent-person duties and the Subpart L appendices are the federal ones. The Iowa chapter carries a rescission date of January 15, 2030 under Iowa Code section 17A.7, which is a scheduled review deadline rather than an expiry of the underlying duties.
29 CFR 1926.451 as adopted by 481—211.1(88)The duty matches the federal text. Only the citation number differs.

How Iowa Enforces 29 CFR 1926.451
Iowa runs an OSHA-approved State Plan administered by Iowa OSHA (IOSH), which covers private-sector construction. Its compliance officers enforce Iowa's own standards, which must be at least as effective as federal OSHA's and may go further. On this subject the rule is 29 CFR 1926.451 as adopted by 481—211.1(88). Iowa OSHA (IOSH) cited 29 CFR 1926.451 24 times in Iowa construction in FY2025 (OSHA Frequently Cited Standards). Iowa applies the federal penalty maximums.
In Iowa, the FY2025 citations under 29 CFR 1926.451 went most often to Masonry Contractors (12) and Residential Remodelers (4). A single inspection can produce several per-instance citations. Recurring self-audits against 29 CFR 1926.451, before an officer arrives, are the most reliable defense.
