Daily Code Talk #15 - IMC Section 115Stop Work Order

Authority (115.1): If work is unsafe or not per code/approved plans, the code official can issue a Stop Work Order (SWO).

This article explains the 2024 IMC model-code path. Before project use, confirm the adopted code edition, local amendments, controlling administrative provisions, permit-application date, and current AHJ procedures. The locally adopted requirements control.

Authority (115.1): If work is unsafe or not per code/approved plans, the code official can issue a Stop Work Order (SWO).

Issuance (115.2): The SWO is written and given to the owner/agent/installer. All cited work stops immediately. The notice explains why and what must be done to resume.

Emergencies (115.3): In an emergency, the official can halt work without prior written notice.

Failure to comply (115.4): Working past an SWO (other than work to remove a hazard/violation) can trigger AHJ (Authority Having Jurisdiction) fines and further enforcement. (MI = manufacturer's installation instructions.)

On Plans: Why It Matters in Design & Construction

Most SWOs stem from three patterns:

1. Deviating from the stamped set - installing something different than what was approved without a permit revision.

2. Ignoring MI/listing limits - clearances, venting requirements, support spacing, or accessory requirements not met in the field.

3. Concealing work before inspection - burying, covering, or backfilling without the required sign-off.

To restart after an SWO: treat it like closing a deficiency. Correct to code and MI, document the fix (photos, marked sheets, listing/MI pages), pass reinspection, and obtain a written lift of the SWO before remobilizing trades. A verbal lift from an inspector is not sufficient - get it in writing.

Code Path: What to Show

M-001: Annotate inspection holds directly on affected sheets - concealed work is the number one stop-work trigger.

For SWO restart: document the correction with photos, code citations, marked sheets, and listing IDs.

Note the AHJ contact and inspection request procedure on the set for the GC and field crew.

Check: After a Stop Work Order

Confirm the abatement plan is documented and submitted to the AHJ before resuming any work.

Verify the SWO release is in writing - verbal clearance is not sufficient.

Confirm the correction covers all systems cited in the SWO - partial fixes will fail reinspection.

Review Risk:

Don't resume work after a Stop Work Order without written AHJ clearance - working past an SWO can trigger legal action.

Don't address only the visible issue - inspectors look for root causes, not just the cited item.

Don't request reinspection before all cited violations are corrected and documented.

Field Tip:

Run this 4-step restart path when an SWO lands:

1. Stabilize: Stop affected work; post shutoffs; secure the area.

2. Diagnose: Photo the issue; pull the approved detail, relevant MI pages, and listing IDs.

3. Abatement plan: Email a one-page correction plan (code cites, fix method, timeline) and request a reinspection window.

4. Resume only after clearance: Keep work visible; pass inspection; get the SWO release in writing.

Masterbuild QA Lens

Most stop-work orders are preventable with a pre-mobilization inspection sequence review. Before first tool touches, confirm with the GC: which stages of work require a hold before cover, which inspections need 48-hour notice, and who calls in the inspection request. If the sequence is not posted on the drawings and communicated to trades, cover-before-approval happens - and an SWO follows.

Drawing / Submittal Check

The permit set should annotate inspection holds directly on the affected sheets - not just on M-001. On slab plans: note underground inspection hold before pour. On framing or coordination drawings: note rough-in hold before wall or ceiling close. On equipment pads: note equipment inspection hold before utilities connect. Holds on the drawings become field awareness; holds only on M-001 get missed.

Common Review Risk

The most common stop-work triggers are: (1) concealed work - ductwork, piping, or equipment covered before inspection; (2) deviating from the approved set without a permit revision; (3) utilities connected before written AHJ authorization. All three are preventable with a pre-mobilization meeting that puts inspection holds on the construction sequence and verifies authorization status before energization.

When To Escalate

Escalate when a Stop Work Order cannot be resolved within 24 hours at the field level, when it affects multiple active trades or occupied-building operations, or when the corrective path requires a PE-sealed revised submittal before work can resume.
