109.1

General. Construction or work for which a permit is required shall be subject to inspection by the code official pursuant to the provisions of this section and Section 104.6. It shall be the duty of the permit holder to cause the construction or work to remain accessible and exposed for inspection purposes until approved. The permit holder shall be liable for any expenses entailed in the removal or replacement of any material required to allow inspection. Approval as a result of an inspection shall not be construed to be an approval of a violation of the provisions of the Construction Codes or of other laws or regulations of the District of Columbia. Regardless of whether the code official inspects the construction or work, it is the responsibility of the permit holder and the individual or entity doing the work to comply with all applicable provisions of the Construction Codes.

109.1.1

Preliminary Inspection. Before issuing a permit, the code official is authorized to examine or cause to be examined all premises for which a permit application has been filed.

109.1.2

Termination of an Inspection. The code official is authorized to terminate an inspection where interference with an inspection occurs or where the code official determines that the work is not sufficiently accessible and exposed for inspection.

109.1.3

Identification of General Contractor or Construction Manager. No inspection by the code official will be scheduled unless and until the applicant has complied with the requirements of Section 105.3.2(8).

109.1.4

Master Tradesperson to be Onsite During Inspections. The master tradesperson to whom a trade permit is issued, or the District of Columbia licensed representative of the master tradesperson, shall be present after the second consecutive rejection of the inspection for the specific scope of work performed under the trade permit. At the discretion of the inspector, the master tradesperson or his licensed representative shall be present during the next or subsequent inspections. Nothing shall limit the code official's authority to require the master tradesperson or his licensed representative to be present for an inspection.

109.2

Required Inspections and Testing. The permit holder shall be responsible for notifying the code official when the stages of construction are reached that require any inspection under Section 109 and for other critical items as directed by the code official. Upon notification, the code official shall make the inspections specified in this Section 109 and such other inspections as necessary, and shall either approve that portion of the construction or shall notify the permit holder of any violations that shall be corrected. The code official shall not be responsible for conducting inspections unless appropriately notified. The code official shall respond to inspection requests without unreasonable delay. It shall be the duty of the person requesting any inspections required by the Construction Codes to provide access to and means for inspection of such work.

Inspection Record. Work requiring a permit shall not be commenced until the permit holder or an agent of the permit holder maintains on the job site an inspection record card or other approved documentation issued by the code official. Such inspection record document shall be made available by the permit holder on the job site until final inspection approval has been granted by the code official. Only an inspector authorized by the Department shall document inspections conducted. Any entry on the inspection record document made by a person other than an authorized inspector shall be grounds for revocation of the permit per Section 111.

109.2.2

Approval Required. Work shall not be done beyond the point indicated in each successive inspection without first obtaining the approval of the code official. The code official shall approve the work or portion thereof that is satisfactory as completed, and, where applicable, shall notify the permit holder or an agent of the permit holder that the work or any portion thereof fails to comply with the Construction Codes. Any portions that do not comply shall be corrected and such portions shall not be covered or concealed until authorized by the code official.
