3116.1.2 Scope. Unless otherwise specifically stated in this section, all prefabricated construction and materials used therein shall conform to all the requirements of this code.
3116.1.3 Definitions.
Prefabricated assembly is a structural unit, the integral parts of which have been built or assembled prior to incorporation in the building.
Prefabricated structures are structures, the parts of which are fabricated and assembled in a central assembly point, where on-site building, electrical, plumbing, and mechanical rough-in inspections occur at the assembly location.
3116.2 Tests of materials. Every approval of a material not specifically mentioned in this code shall incorporate as a proviso the kind and number of nationally recognized tests to be made.
3116.3 Tests of assemblies. The building official may require special tests to be made on assemblies to determine their durability and weather resistance.
3116.4 Connections. Every device used to connect prefabricated assemblies shall be designed as required by this code and shall be capable of developing the strength of the members connected, except in the case of members forming part of a structural frame as specified in Chapter 16. Connections shall be capable of withstanding uplift forces as specified in this code and in Chapter 16.
3116.5 Pipes and conduits. In structural design, due allowance shall be made for any material to be removed for the installation of pipes, conduit, and other equipment.
3116.6 Permits, materials, plans, fees, certificate, and inspections.
3116.6.1 Materials. Materials and the assembly thereof shall be inspected to determine compliance with this code. Every material shall be graded, marked, or labeled as required elsewhere in this code.
3116.6.2 Plans. One complete set of plans and specifications shall be submitted to the building inspection division of planning and development services for approval prior to issuing a building permit for a prefabricated structure. Plans shall be of sufficient detail and clarity to indicate compliance with all applicable codes (electrical, plumbing, building, mechanical, and zoning).
3116.6.3 Permits and fees. Permit fees shall be as follows:
1. The fee for a building permit shall conform to Tables 1-A and 1-B, and the plan review fee, if applicable, shall be in accordance with Table 1-C.

3116.6.4 Certificate. A certificate of approval shall be furnished with every prefabricated assembly and prefabricated structure, except where the assembly is readily accessible to inspection at the site. The certificate of approval shall certify that the assembly in question has been inspected and meets all the requirements of this code. When mechanical equipment is installed so that it cannot be inspected at the site, the certificate of approval shall certify that such equipment complies with the laws applying thereto.
3116.6.5 Certifying agency. To be acceptable under this code, every certificate of approval shall be made by the approved agency.
3116.6.6 Field erection. The building official shall inspect placement of prefabricated assemblies at the building site to determine compliance with this code. Installation and finishing work at the building site must be performed by locally licensed contractors where required. Final inspections are to be made after the installation and finishing work has been completed and the building is ready for occupancy.
3116.6.7 Continuous inspection. If continuous inspection is required for certain materials where construction takes place on the site, it shall also be required where the same materials are used in prefabricated construction.
Exception: Continuous inspection will not be required during prefabrication if the approved agency certifies to the construction and furnishes evidence of compliance.
3116.6.8 Moving permits. A moving permit shall be obtained for each prefabricated structure being moved within the city in accordance with Section 3404 Moved Buildings. No person except a building mover licensed pursuant to subsection 3404.2 of Section 150.017 of the Code of Ordinances of Sioux Falls shall move a prefabricated structure or part thereof across, along, or over public property.

The applicant shall secure insurance covering any possible liability that could incur during demolition.
3303.6 Utility connections. Service utility connections shall be discontinued and capped in accordance with the approved rules and the requirements of the applicable governing authority.
