Minn. R. 1300 § 1300.0210

Subpart 1. General.
Construction or work for which a permit is required is subject to inspection by the building official and the construction or work shall remain accessible and exposed for inspection purposes until approved. Approval as a result of an inspection is not approval of a violation of the code or of other ordinances of the jurisdiction. Inspections presuming to give authority to violate or cancel the provisions of the code or of other ordinances of the jurisdiction are not valid. It shall be the duty of the permit applicant to cause the work to remain accessible and exposed for inspection purposes. Neither the building official nor the jurisdiction is liable for expense entailed in the removal or replacement of any material required to allow inspection.

Subp. 2. Preliminary inspection.
Before issuing a permit, the building official may examine, or cause to be examined, buildings, structures, and sites for which an application has been filed.

Subp. 3. Inspection record card.
The building official shall identify which inspections are required for the work requiring a permit. Work requiring a permit shall not be commenced until the permit holder or an agent of the permit holder has posted or otherwise made available an inspection record card that allows the building official to conveniently make all required entries regarding inspection of the work. This card shall be maintained and made available by the permit holder until final approval has been granted by the building official.

Subp. 4. Inspection requests.
The building official shall provide the applicant with policies, procedures, and a timeline for requesting inspections. The person doing the work authorized by a permit shall notify the building official that the work is ready for inspection. The person requesting an inspection required by the code shall provide access to and means for inspection of the work.

Subp. 5. Approval required.
Work shall not be done beyond the point indicated in each successive inspection without first obtaining the approval of the building official. The building official, upon notification, shall make the requested inspections and shall either indicate the portion of the construction that is satisfactory as completed or notify the permit holder or an agent of the permit holder of any failures to comply with the code. Any portion that does not comply shall be corrected and the portion shall not be covered or concealed until authorized by the building official.

Subp. 6. Required inspections.
The building official, upon notification, shall make the inspections in this part. In addition to the inspections identified in this subpart, see applicable rule chapters in part 1300.0050 for specific inspection and testing requirements.
