29 CFR 1926.850

29 CFR 1926.850 requires preparatory steps before any demolition begins: a competent person must make an engineering survey of the structure to determine the condition of the framing, floors, and walls and the possibility of unplanned collapse, utilities must be shut off or controlled, and the survey must be documented in writing.

The #1 confusion: The engineering survey must be done and documented BEFORE demolition starts

What 29 CFR 1926.850 requires (plain English)

29 CFR 1926.850 governs the preparatory operations that must be completed before any demolition begins. Demolition is inherently hazardous, it deliberately compromises a structure's integrity, so the standard front-loads the safety work into an assessment done before the first element is removed.

Its central requirement is that, prior to permitting employees to start demolition, a competent person make an engineering survey of the structure to determine the condition of the framing, floors, and walls and the possibility of unplanned collapse of any portion, with adjacent structures where workers may be exposed similarly checked; the employer must have written evidence that the survey was performed. The standard also requires that all utilities (electric, gas, water, steam, and others) be located and shut off, capped, or controlled before demolition, and that hazardous materials and residual chemicals be identified and addressed.

1926.850 opens Part 1926 Subpart T (demolition) and works with the excavation, hazardous-materials, and asbestos standards, since demolition often disturbs asbestos, lead, and other hazards. It ensures that the people tearing a structure down first understand how it stands up.

The regulatory text

“Prior to permitting employees to start demolition operations, an engineering survey shall be made, by a competent person, of the structure to determine the condition of the framing, floors, and walls, and possibility of unplanned collapse of any portion of the structure.”

Common Demolition Prep violations

Deficiencies OSHA cites under 29 CFR 1926.850 include the ones below, in no particular order. Distinct deficiencies can be cited as separate items, and each serious item carries up to $16,550 (2026). Broader per-instance stacking exists but is a discretionary, case-by-case OSHA enforcement policy, not an automatic multiplier.

No engineering survey by a competent person before demolition (1926.850(a)).
No written evidence that the survey was performed (1926.850(a)).
Utilities not located and shut off, capped, or controlled before demolition (1926.850(b)).
Adjacent exposed structures not checked (1926.850(a)).
Hazardous materials not identified before demolition (1926.850).

The engineering survey comes first, before any demolition, and in writing

The most common and dangerous shortcut is starting demolition and assessing hazards as the crew goes. 1926.850(a) requires the opposite: prior to permitting employees to start demolition, a competent person must survey the structure for its condition and the possibility of unplanned collapse, and the employer must have written evidence the survey was done. Demolition deliberately removes load paths, so without first understanding how the structure carries its loads, a crew can trigger a collapse. The survey, plus locating and shutting off utilities and identifying hazardous materials, is preparatory by design, and doing it after the work begins defeats the purpose.

What OSHA inspectors look for

A compliance officer asks for the written engineering survey done by a competent person before demolition started, checks that utilities (gas, electric, water, steam) were located and shut off or controlled, and that hazardous materials were identified. Starting demolition with no documented survey is the classic finding.

Example: how a violation is cited

A crew begins demolishing a building with no engineering survey; a compromised floor gives way under equipment and workers, and an unlocated gas line is struck. OSHA cites 1926.850(a) because a competent person must survey the structure and document it before demolition, with willful classifications reaching $165,514.

Demolition Prep compliance checklist

Use this to evaluate your compliance with 29 CFR 1926.850. Each item is a key requirement OSHA may verify during an inspection.

Have a competent person make an engineering survey of the structure before any demolition.
Determine the condition of framing, floors, and walls and the possibility of unplanned collapse.
Check adjacent structures where workers could be exposed.
Keep written evidence that the survey was performed.
Locate and shut off, cap, or control all utilities before demolition begins.
Identify and address hazardous materials such as asbestos and residual chemicals.

2026 penalties for 29 CFR 1926.850

Maximums set by 29 CFR 1903.15(d). 2026 amounts unchanged from 2025 (no CPI adjustment; OMB M-26-11). Not an increase. The 2025 OSHA penalty levels remain in effect for 2026; OSHA made no inflation adjustment for 2026. 29 CFR 1903.15 identifies January 15, 2025 as the effective reference for these amounts, while OSHA's public penalties page currently references penalties assessed after Jan. 15, 2026.

Violation type	Minimum	Maximum	When it applies
Serious	$1,085	$16,550	Substantial probability of death or serious physical harm.
Other-Than-Serious	$0	$16,550	Relates to safety/health but unlikely to cause death or serious harm.
Willful	$11,823	$165,514	Intentional, knowing, or voluntary disregard of the requirement.
Repeated	$4,256	$165,514	A substantially similar violation cited within the last 5 years.
Failure to Abate	None	$16,550/day	up to $16,550 per day; total capped at 30x the daily amount (FOM Ch.6)

Demolition citations follow collapses and utility strikes and are high-gravity. Serious violations reach $16,550 and willful or repeat violations $165,514; a missing engineering survey is a frequent finding.

Maximums and the willful minimum are set by 29 CFR 1903.15(d); the serious and repeated minimums are OSHA policy floors from its annual penalty adjustment memo. OSHA applies gravity-based and size, good-faith and history reductions (FOM CPL 02-00-164 Ch.6). Estimates only, not legal advice.

The business case for Demolition Prep compliance

Demolition removes the structure that holds a building up, so an unplanned collapse can bury a crew, and an unlocated gas or electrical line can cause an explosion or electrocution. The engineering survey forces someone competent to understand the structure and its hazards before the first wall comes down, which is the difference between a controlled demolition and a disaster.

Frequently asked questions about 29 CFR 1926.850

What must be done before demolition starts?

Under 1926.850(a), before employees start demolition a competent person must make an engineering survey of the structure to determine the condition of the framing, floors, and walls and the possibility of unplanned collapse, and adjacent exposed structures must be similarly checked. The employer must have written evidence the survey was performed, and utilities must be located and shut off or controlled first.

Does the demolition engineering survey have to be in writing?

Yes. 1926.850(a) requires the employer to have in writing evidence that the engineering survey by a competent person was performed. This documentation confirms the structure's condition and collapse potential were assessed before demolition began, and it is one of the first things OSHA asks for after a demolition collapse.

What has to happen to utilities before demolition?

Under 1926.850(b), before demolition begins all electric, gas, water, steam, sewer, and other service lines must be located, then shut off, capped, or otherwise controlled outside the building line. If maintaining any utility is necessary during demolition, it must be temporarily relocated and protected. An unlocated live gas or electrical line struck during demolition can cause an explosion or electrocution.

Does demolition trigger asbestos and hazmat requirements?

Often, yes. Older buildings frequently contain asbestos, lead paint, PCBs, and residual chemicals, and demolition disturbs them. So 1926.850's preparatory identification of hazardous materials connects to the asbestos standard (1926.1101), the lead standard (1926.62), and hazardous-waste requirements. Identifying these before demolition lets the employer plan abatement and worker protection rather than exposing the crew unexpectedly.

Regulatory history of 29 CFR 1926.850

1926.850 opens Part 1926 Subpart T (demolition) and has required a pre-demolition engineering survey by a competent person since OSHA's early construction standards. The requirement reflects that demolition's greatest hazard, unplanned collapse, is best prevented by understanding the structure before removing any of it.
