Codes & Standards Flashcards

What is the primary reference standard for accessible design requirements in ICC codes?

Answer: ANSI A117.1

ICC A117.1, 'Accessible and Usable Buildings and Facilities,' is the technical accessibility standard referenced by the IBC for accessible design.

Under the IBC, what distinguishes a 'high-rise building' and what additional requirements apply?

Answer: Buildings over 75 ft in height above the lowest level of fire department access

The IBC defines high-rise buildings as those with an occupied floor more than 75 feet above the lowest level of fire department vehicle access, triggering additional fire and life safety requirements.

Which ICC code governs the installation of plumbing systems, including water supply and drainage?

Answer: International Plumbing Code (IPC)

The IPC covers the design and installation of plumbing systems, including potable water supply, sanitary drainage, and fixtures.

What is the purpose of the 'International Green Construction Code' (IgCC)?

Answer: To provide a comprehensive framework for sustainable site, water, energy, and indoor environmental quality beyond the IECC

The IgCC is a whole-building sustainability code that addresses site impacts, water conservation, energy efficiency, and indoor air quality beyond minimum energy code requirements.

How does the IBC treat buildings with mixed occupancies under the 'separated occupancies' approach?

Answer: Each occupancy area is separated by fire-resistance-rated construction and each portion independently meets its own occupancy requirements

Under the separated occupancies approach, fire-resistance-rated separations allow each portion to be independently regulated by its own occupancy requirements.

What is a 'variance' in the context of building codes?

Answer: A formal permission granted by the authority having jurisdiction to deviate from a specific code requirement

A variance is an official relief from a specific code provision granted by the AHJ when strict compliance creates an undue hardship without compromising safety.

Under the ICC framework, what body holds the 'Authority Having Jurisdiction' (AHJ) over code enforcement?

Answer: The local or state government official or agency designated by law to enforce the code

The AHJ is the organization, office, or individual legally responsible for enforcing the code requirements, typically the local building official or fire marshal.
