For SI: 1 inch = 25.4 mm, 1 pound per square foot = 0.0479 kPa, 1 square inch = 645 mm2, 1 pound = 4.45N.
   a.   Elevated garage floors shall be capable of supporting the uniformly distributed live load or a 2,000-pound concentrated load applied on an area of 4 1/2 inches by 4 1/2 inches, whichever produces the greater stresses.
   b.   Uninhabitable attics without storage are those where the clear height between joists and rafters is not more than 42 inches, or where there are not two or more adjacent trusses with web configurations capable of accommodating an assumed rectangle 42 inches in height by 24 inches in width, or greater, within the plane of the trusses. This live load need not be assumed to act concurrently with any other live load requirements.
   c.   Individual stair treads shall be capable of supporting the uniformly distributed live load or a 300-pound concentrated load applied on an area of 2 inches by 2 inches, whichever produces the greater stresses.
   d.   A single concentrated load applied in any direction at any point along the top. For a guard not required to serve as a handrail, the load need not be applied to the top element of the guard in a direction parallel to such element.
   e.   See Section R507.1 for decks attached to exterior walls.
   f.   Guard in-fill components (all those except the handrail), balusters, and panel fillers shall be designed to withstand a horizontally applied normal load of 50 pounds on an area equal to 1 square foot. This load need not be assumed to act concurrently with any other live load requirement.
   g.   Uninhabitable attics with limited storage are those where the clear height between joists and rafters is 42 inches or greater, or where there are two or more adjacent trusses with web configurations capable of accommodating an assumed rectangle 42 inches in height by 24 inches in width, or greater, within the plane of the trusses. The live load need only be applied to those portions of the joists or truss bottom chords where all of the following conditions are met:
      1.   The attic area is accessed from an opening not less than 20 inches in width by 30 inches in length that is located where the clear height in the attic is not less than 30 inches.
      2.   The slopes of the joists or truss bottom chords are no greater than 2 inches vertical in 12 units horizontal.
      3.   Required insulation depth is less than the joist or truss bottom chord member depth.
      The remaining portions of the joists or truss bottom chords shall be designed for a uniformly distributed concurrent live load of not less than 10 pounds per square foot.
   h.   Glazing used in handrail assemblies and guards shall be designed with a load adjustment factor of 4. The load adjustment factor shall be applied to each of the concentrated loads applied to the top of the rail, and to the load on the in-fill components. These loads shall be determined independent of one another, and loads are assumed not to occur with any other live load.
   i.   Where the top of a guard system is not required to serve as a handrail, the single concentrated load shall be applied at any point along the top in the vertical downward direction and in the horizontal direction away from the walking surface. Where the top of a guard is also serving as the handrail, a single concentrated load shall be applied in any direction at any point along the top. Concentrated loads shall not be applied concurrently.

   3116.1.1 Purpose. The purpose of this section is to regulate materials and establish methods of safe construction where any structure or portion thereof is wholly or partially prefabricated.
   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.

   3116.6.2 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.

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.
