The Corridor the Department Approved by Mistake
Eight months ago the department issued a permit for a 9,000-square-foot single-story building of Type IIB, sprinklered construction, containing 6,000 square feet of office (B) and 3,000 square feet of storage (S-1). The approved drawings show a 36-inch-wide exit access corridor serving the office suite, a building occupant load of 60, and two exits. The corridor was framed last week at 36 inches. While reviewing an unrelated project, the plans examiner realizes the approved set she signed shows the corridor at 36 inches, that her comment letter never raised it, and that the corridor serves 60 office occupants, which requires 44 inches. The contractor has already framed, insulated, and closed one side of the corridor and states that the stamped approval means the department cannot require a change. The owner has a tenant scheduled to move in within 30 days and is asking for a temporary certificate of occupancy for the storage portion only.
1. What authority and duty does the building official have now that the department's own approval contained the error?
Read the worked answer
Approval of construction documents authorizes work that complies with the code; it does not convert noncompliant work into compliant work. The building official retains authority to correct errors, to suspend or revoke a permit issued in error, and to issue a stop-work order where work is contrary to the code (IBC §115). Responsibility for code compliance remains with the owner and the design professional; the permit is not a warranty of compliance.
Practically: verify the facts first. Measure the corridor, confirm the occupant load of the space it serves, and check whether any exception applies to the width requirement. Then issue a written correction notice that states the requirement, the measured condition, and the required action. Decide the stop-work scope deliberately: a stop-work order limited to the corridor may be enough to prevent further concealment, while a building-wide stop would be disproportionate and would invite a challenge.
The department should also document internally that the error originated in its own review. That documentation protects the examiner and lets the building official decide the tone of the response to the owner, without changing the technical outcome.
2. How should the department handle the fact that its own review missed the deficiency, and what should it tell the contractor?
Read the worked answer
Tell the truth in writing and keep the technical requirement separate from the fault question. A letter that acknowledges the review error, restates the measured condition and the code requirement, and specifies what will satisfy it is both accurate and defensible. Do not let the field inspector improvise a different standard from the one in the correction notice.
The contractor's argument that a stamped approval bars any change has no basis in the code, but the department should recognize the practical cost. Offer an expedited review of a revised detail: a furred-out wall, a reconfiguration of the suite, or a reduction of the occupant load of the space served if the design genuinely supports it. If the owner seeks a modification, evaluate it on the code criteria for practical difficulty. The cost of correcting a self-created design error is generally weak evidence of practical difficulty, and the request must be assessed on its merits rather than on the origin of the mistake.
Follow up in the file with dates, names, and copies of the correspondence, because this is the type of error that can become a claim.
3. Can a temporary certificate of occupancy be issued for the storage portion while the corridor is corrected?
Read the worked answer
Possibly, but only on findings, not on the schedule. A certificate of occupancy is issued for a building or a portion of a building, and the temporary or partial occupancy provisions let the building official allow occupancy before all work is complete where the portion is safe for its intended use.
Test the storage portion independently: Does it have its own code-compliant exiting that does not rely on the 36-inch corridor? Is the sprinkler system in service and monitored for the occupied area? Is fire department access available? Are the fire-resistance features affecting that portion complete? Is there separation from construction activity, and is the construction itself controlled so occupants are not exposed to hazards? Is any remaining work incapable of jeopardizing the occupants?
If those findings can be made, issue a written temporary certificate with explicit conditions, a defined area, and an expiration date, and require the life-safety systems to remain in service. If the storage area's only path of egress runs through the deficient corridor, the answer is no until the corridor is corrected. When the corridor is corrected and inspected, close out the permit with a final certificate for the whole building.
