At what height is fall protection required in construction?

In construction, OSHA generally requires fall protection when an employee works 6 feet or more above a lower level. The residential rule, 29 CFR 1926.501(b)(13), and the unprotected sides-and-edges rule, 1926.501(b)(1), both set the trigger at 6 feet (1.8 m). Lower-trigger exceptions apply to scaffolds (10 feet, 1926.451(g)(1)) and steel erection (15 feet, 1926.760(a)(1)).

Is the OSHA fall-protection height 4 feet or 6 feet?

It depends on the standard that governs the work. General industry under 29 CFR 1910.28(b)(1)(i) triggers at 4 feet. Construction under 29 CFR 1926.501 triggers at 6 feet. The same job site can carry both, so identify whether the activity is construction or general industry before applying a threshold.

What is the most-cited OSHA fall-protection standard?

29 CFR 1926.501(b)(13), the residential-construction fall-protection requirement, is the single most-cited construction standard in OSHA’s enforcement record, with 109,561 citations and roughly $373 million in total assessed penalties. The general unprotected-edges provision, 1926.501(b)(1), is also among the most-cited at 51,382 citations.

What is the fall-protection trigger for steel erection?

29 CFR 1926.760(a)(1) requires fall protection for steel-erection employees on a walking/working surface with an unprotected side or edge "more than 15 feet (4.6 m) above a lower level." Steel erection also recognizes positioning-device and fall-restraint systems alongside guardrails, nets, and personal fall arrest.

Short answer Cleared

In construction, OSHA requires fall protection when an employee works 6 feet (1.8 m) or more above a lower level, under 29 CFR 1926.501(b)(13) and 1926.501(b)(1). Different triggers apply elsewhere: general industry at 4 feet (1910.28), scaffolds at 10 feet (1926.451), and steel erection at 15 feet (1926.760). The compliant options are the same throughout: a guardrail system, a safety net system, or a personal fall arrest system.

Key takeaways

In construction, fall protection is generally required at 6 feet above a lower level under 29 CFR 1926.501(b)(13) and 1926.501(b)(1).
General industry uses a lower 4-foot trigger under 29 CFR 1910.28(b)(1)(i).
Scaffolds trigger at 10 feet (1926.451(g)(1)); steel erection at 15 feet (1926.760(a)(1)). Both are exceptions to the 6-foot construction rule.
1926.501(b)(13) is the single most-cited construction standard in the OSHA record, with 109,561 citations and roughly $373 million in assessed penalties.
The compliant options are the same across triggers: a guardrail system, a safety net system, or a personal fall arrest system.

At what height is fall protection required?

There is no single OSHA fall-protection height: the trigger depends on the standard that governs the work. The schedule below lists each controlling threshold, with the exact CFR section. Construction defaults to 6 feet; the lower-trigger exceptions (scaffolds, steel erection) and the 4-foot general industry rule are quoted and sourced in the sections that follow.

OSHA fall-protection trigger heights by activity and CFR section
CFR section	Work / context	Trigger height
1926.501(b)(13)	Residential construction	6 feet
1926.501(b)(1)	Unprotected sides & edges (general construction)	6 feet
1910.28(b)(1)(i)	General industry walking-working surfaces	4 feet
1926.451(g)(1)	Scaffolds (construction)	10 feet
1926.760(a)(1)	Steel erection	15 feet

Construction: the 6-foot rule under 1926.501

29 CFR 1926.501

29 CFR 1926.501 is titled "Duty to have fall protection." It sets the construction baseline: an employer must protect employees from falls at 6 feet. Two provisions carry most of the enforcement weight. The general unprotected-edges rule, 1926.501(b)(1), governs any walking/working surface; the residential rule, 1926.501(b)(13), is the single most-cited construction standard in OSHA’s record.

"Each employee on a walking/working surface (horizontal and vertical surface) with an unprotected side or edge which is 6 feet (1.8 m) or more above a lower level shall be protected from falling by the use of guardrail systems, safety net systems, or personal fall arrest systems."

29 CFR 1926.501(b)(1) · osha.gov

"Each employee engaged in residential construction activities 6 feet (1.8 m) or more above lower levels shall be protected by guardrail systems, safety net system, or personal fall arrest system unless the employer can demonstrate that it is infeasible or creates a greater hazard to use these systems."

29 CFR 1926.501(b)(13) · osha.gov

The performance criteria for each option, guardrail strength, net clearance, anchorage and arrest forces, live in 29 CFR 1926.502, and the training duty lives in 1926.503. Choosing a method under 1926.501 without meeting the 1926.502 criteria is itself a citable condition.

On record

1926.501(b)(13) carries 109,561 citations and roughly $373 million in assessed penalties, the most of any construction standard in OSHA’s record. The general unprotected-edges rule, 1926.501(b)(1), adds 51,382 citations, and the related ladder rule 1926.1053(b)(1) adds 50,876. Together those three lead the construction citation record.

General industry: the 4-foot rule under 1910.28

29 CFR 1910.28

General industry, meaning manufacturing, warehousing, and most non-construction workplaces, is governed by 29 CFR 1910.28, "Duty to have fall protection and falling object protection." Its trigger is lower than construction: 4 feet.

"Except as provided elsewhere in this section, the employer must ensure that each employee on a walking-working surface with an unprotected side or edge that is 4 feet (1.2 m) or more above a lower level is protected from falling by one or more of the following: Guardrail systems; Safety net systems; or Personal fall protection systems."

29 CFR 1910.28(b)(1)(i) · osha.gov

Because a single site can host both construction and general-industry activity, classify the work first. The trigger height follows from how the activity is classified, regardless of where it happens.

The exceptions: scaffolds (10 ft) and steel erection (15 ft)

SUBPARTS L · R

Two construction activities carry their own triggers that override the 6-foot default. Scaffolds are governed by Subpart L; steel erection by Subpart R.

"Each employee on a scaffold more than 10 feet (3.1 m) above a lower level shall be protected from falling to that lower level."

29 CFR 1926.451(g)(1) · osha.gov

"…each employee engaged in a steel erection activity who is on a walking/working surface with an unprotected side or edge more than 15 feet (4.6 m) above a lower level shall be protected from fall hazards by guardrail systems, safety net systems, personal fall arrest systems, positioning device systems or fall restraint systems."

29 CFR 1926.760(a)(1) · osha.gov

Scaffold fall hazards are heavily cited in their own right: 1926.451(g)(1) carries 26,601 citations. Note that steel erection recognizes two additional compliant methods, positioning-device and fall-restraint systems, that the general 1926.501 rule does not enumerate.
