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). Separate triggers apply to scaffolds (more than 10 feet, 1926.451(g)(1)) and steel erection (more than 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 or more, and construction under 29 CFR 1926.501 triggers at 6 feet or more. 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. Connectors and employees in a controlled decking zone are protected under 1926.760(b) and (c) instead.

Short answer

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, which are 4 feet or more for general industry (1910.28), more than 10 feet for scaffolds (1926.451), and more than 15 feet for steel erection (1926.760). The compliant options depend on the standard that applies, and guardrail systems, safety net systems, and personal fall arrest systems are the most common options. Steel erection adds positioning device systems and fall restraint systems and allows a controlled decking zone for initial metal decking work, and scaffold options depend on the scaffold type.

Key takeaways

In construction, fall protection is generally required at 6 feet or more above a lower level under 29 CFR 1926.501(b)(13) and 1926.501(b)(1).
General industry uses a lower trigger of 4 feet or more under 29 CFR 1910.28(b)(1)(i).
Scaffolds trigger at more than 10 feet (1926.451(g)(1)) and steel erection at more than 15 feet (1926.760(a)(1)), and both have their own trigger instead of 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 depend on the standard that applies. Guardrail, safety net, and personal fall arrest systems are the most common options, steel erection adds positioning device and fall restraint systems, and scaffold options depend on the scaffold type.

At what height is fall protection required?

There is no single OSHA fall-protection height, because the trigger depends on the standard that governs the work. The schedule below lists each controlling threshold with its exact CFR section, and construction defaults to 6 feet or more. The scaffold and steel erection triggers (more than 10 and more than 15 feet) 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 or more
1926.501(b)(1)	Unprotected sides and edges (general construction)	6 feet or more
1910.28(b)(1)(i)	General industry walking-working surfaces	4 feet or more
1926.451(g)(1)	Scaffolds (construction)	More than 10 feet
1926.760(a)(1)	Steel erection	More than 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, which is that an employer must protect employees from falls of 6 feet or more. Two provisions are the most-cited construction standards. The general unprotected-edges rule, 1926.501(b)(1), governs any walking/working surface, and 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 another provision in paragraph (b) of this section provides for an alternative fall protection measure."

29 CFR 1926.501(b)(13), osha.gov

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

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, the three standards 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 4 feet or more, which is lower than the construction trigger.

"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, such as personal fall arrest, travel restraint, or positioning 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 AND R

Scaffolds and steel erection carry their own triggers that replace the 6-foot default, with scaffolds governed by Subpart L and steel erection governed 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, and 1926.451(g)(1) carries 26,601 citations. Steel erection also recognizes two additional compliant methods that 1926.501(b)(1) does not list, which are positioning-device and fall-restraint systems. Scaffold fall protection is set by scaffold type in 1926.451(g)(1)(i) through (vii), and safety nets are not among the listed options.
