Rule 24.301.142 - MODIFICATIONS TO THE INTERNATIONAL BUILDING CODE APPLICABLE ONLY TO THE DEPARTMENT'S CODE ENFORCEMENT PROGRAM
Current through Register Vol. 6, March 22, 2024
(1) The following modifications to the International Building Code are applicable only to the department's building code enforcement program. The referenced sections remain without amendment for local government building code enforcement programs.
(2) The department will use 50-60-109 and 50-60-110, MCA, in cases requiring prosecution in lieu of Section 114 of the IBC. When a person fails to submit required plans, obtain a permit, correct plans, or comply with an order of the department, the department, as authorized by 50-60-109, MCA, may bring civil action to enjoin the person from constructing or using the building.
(3) No plumbing, mechanical, or electrical permit will be issued for a building or structure under the jurisdiction of the department, until:
(4) An owner seeking to do work that the owner believes is not subject to a building code requirement shall provide to the department in writing, either electronically or via the U.S. mail, if in the state's jurisdiction, any documentation or information that it may reasonably require so that the department may determine whether the work is subject to the building code requirement. The documentation or information provided may be required to be in the form of an affidavit or affirmation.
(5) Subsection 107.1 of the IBC is amended to read as follows: "Submittal documents consisting of construction documents, statement of special inspections, geotechnical report, and other data shall be submitted electronically or on paper no larger than 11 by 17 inches. The construction documents shall be prepared by a registered design professional as required by specific provisions throughout the International Building Code (IBC) as adopted by the department in ARM 24.301.131. The department is authorized to waive the submission of construction documents and other data not required to be prepared by a registered design professional if it is found that the nature of the work applied for is such that review of construction documents is not necessary to obtain compliance with the IBC as adopted by the department."
(6) Subsection 111.1 of the IBC is amended with the addition of the following: "On a case-by-case basis, the building official or his agent may grant the owner permission to occupy and use a building or portions thereof prior to completion of the project when the building official or his agent finds the building or structure to be in substantial compliance with the intent of the International Building Code."
(7) Subsection 111.2 of the IBC is amended to read:
(8) The department will use the applicable provisions of the Montana Administrative Procedure Act in all cases of appeal in lieu of Section 113 of the IBC.
(9) Subsection 1809.5 of the IBC requires that footings and foundations shall extend below the frost line. In all areas of the state outside of certified local government jurisdictions, the minimum depth from finished grade to the bottom of footings shall be three feet for single story wood or metal frame buildings, and four feet for multistory or masonry buildings. Buildings located on highly expansive or unstable soils may need engineered footings and foundation walls that extend below the minimum depths indicated above. At the discretion of the building official, the above minimum depths may not be required for properly designed so-called monolithic slabs for single story storage and similar use buildings. The building official may require monolithic slabs to be designed and stamped or certified by a Montana registered engineer who practices structural design. The design and stamp of a Montana licensed architect may be accepted in lieu of an engineer's stamp when the monolithic slab design is an incidental part of an architectural building design, as allowed by 37-67-103, MCA.
