If a request is properly made, the Authority Having Jurisdiction shall not be required to perform the inspection on the requested date, but shall make reasonable efforts to perform the requested inspection on the requested date or as soon thereafter as is practicable under the circumstances.
It shall be the duty of the person requesting inspections, in accordance with this code, to provide access to and means for inspection of such work. After inspection, the Authority Having Jurisdiction shall approve the inspected work if it complies with the requirements of this code and the approved plans for the building permit issued for the work.
As part of any inspection made under this code, the Authority Having Jurisdiction may require verification that the work being inspected was performed by a plumbing journey worker and/or contractor currently licensed in the State of Hawaii. The failure to verify that work under inspection was performed by an appropriately licensed professional will be adequate grounds for the Authority Having Jurisdiction to determine that the work fails inspection.
In addition to any fees payable under ROH Chapter 18, a person requesting an inspection will be required to pay an inspection fee. A person that requests an inspection to occur during normal business hours shall pay the city a fee of $50 per hour for each hour that is used to perform the inspection, which includes time used to travel to and from the inspection location. A person may also request an inspection to occur outside of normal business hours. A request for an inspection to be conducted outside of normal business hours may be approved or denied at the discretion of the Authority
Having Jurisdiction, based on the nature of the work to be inspected and the availability of personnel to perform the inspection. The fee for an inspection to be conducted outside of normal business hours is $75 for each hour that is used to perform the inspection, including time used to travel to and from the inspection location. For the purposes of this section, normal business hours are 8:00 a.m. to 4:00 p.m. on a day on which the city is open for business.
In calculating inspection fees due under this section, the person requesting the inspection will be billed for one hour of time for inspections that take up to one hour and half the hourly rate for each additional half hour or portion thereof used to perform the inspection.

(16) Amending Section 105.2.6. Section 105.2.6 is amended to read:
105.2.6 Reinspections. If an inspection is made by the Authority Having Jurisdiction and additional inspections are necessary because less than all of the work requiring inspection is approved, the Authority Having Jurisdiction may require a reinspection of the work that has not been approved. When a reinspection is required, a reinspection fee will be assessed.
Reinspections may be requested in the same manner as requests for initial inspections under Section 105.2.3 and will be billed in the same manner described therein.
Reinspections will not be provided until all outstanding inspection fees and the fee for reinspection have been paid.
(17) Adding Section 105.2.7. Section 105.2.7 is added to read:
105.2.7 Plumbing Special Inspection. The Authority Having Jurisdiction may require work governed by this code to be subject to a plumbing special inspection when deemed necessary based on the nature of the work or resources of the Authority Having Jurisdiction. Plumbing special inspections must be performed by appropriately Registered Design Professionals currently licensed in the State of Hawaii that are not involved in performing the work that will be inspected.
Plumbing special inspectors are to be hired and paid by the applicant and may be required to provide the Authority Having Jurisdiction with proof of their qualifications to perform the required inspections.
Plumbing special inspectors shall review the approved construction documents prior to the commencement of work and document the performance of work in compliance with the approved construction documents and the requirements of this code in reports that will be provided to the Authority Having Jurisdiction, the applicant, and the Registered Design Professional engineer of record, on request.
When work that is subject to a plumbing special inspection is complete, the plumbing special inspector shall submit a final signed report stating that the inspected work was completed in compliance with the approved construction documents and the requirements of this code.
Plumbing special inspectors will provide written documentation to the Authority Having Jurisdiction demonstrating the plumbing special inspectors’ competence and relevant experience or training in each type of inspection they will perform. Inspector personnel will not be allowed to perform inspections without these qualifications unless directly supervised by the qualified, responsible plumbing special inspector.
(18) Amending Section 106.2. Section 106.2 is amended to read:

In addition to the information required for a notice of violation under Section 106.2, a stop work order must contain a concise description of the work that is prohibited by the stop work order.
