1. What is the primary purpose of the International Existing Building Code
(IEBC)?
A. To require every existing building to be reconstructed entirely under
newconstruction requirements
B. To regulate only newly constructed commercial buildings
C. To provide requirements for the repair, alteration, addition, relocation,
and change of occupancy of existing buildings while allowing
appropriate flexibility
D. To replace all local zoning ordinances
,Rationale: The IEBC is specifically intended to facilitate the safe reuse and
rehabilitation of existing buildings. It permits controlled alternatives to full
new-construction compliance while maintaining appropriate levels of
structural, fire, life-safety, and accessibility protection.
2. Which project is most directly within the scope of the IEBC?
A. Construction of a new subdivision on undeveloped land
B. Construction of a new detached house with no existing structure
C. Alteration of an existing commercial building
D. Manufacture of construction equipment
Rationale: The IEBC addresses existing buildings undergoing repair,
alteration, addition, relocation, or change of occupancy. New construction
is generally governed by the applicable new-building codes rather than the
IEBC.
3. What is an important reason the IEBC does not generally require every
existing building undergoing rehabilitation to comply fully with all
new-construction requirements?
A. Existing buildings are exempt from all safety requirements
B. Existing buildings cannot legally be inspected
,C. Requiring complete new-construction compliance for every existing
building could make reasonable rehabilitation prohibitively difficult or
costly
D. Existing buildings are presumed structurally perfect
Rationale: The IEBC recognizes that many existing buildings were legally
constructed under earlier requirements. Its approach seeks to encourage
reuse while requiring reasonable upgrades and maintaining basic safety
levels rather than automatically imposing every new-construction
requirement.
4. Which three primary compliance methods are provided for alterations,
additions, and changes of occupancy under the IEBC?
A. Structural, electrical, and plumbing methods
B. Residential, commercial, and industrial methods
C. Prescriptive, Work Area, and Performance compliance methods
D. Historic, seismic, and flood methods
Rationale: The IEBC provides three principal compliance approaches: the
Prescriptive Compliance Method, the Work Area Compliance Method, and
the Performance Compliance Method. The applicant selects the applicable
method subject to the code and jurisdictional requirements.
, 5. Which IEBC chapter governs repairs?
A. Chapter 5
B. Chapter 8
C. Chapter 4
D. Chapter 12
Rationale: Chapter 4 addresses repairs to existing buildings. It operates
independently of the three principal compliance methods and establishes
requirements for repairing existing components and conditions.
6. Under the IEBC, which compliance method is associated with Chapter
5?
A. Performance Compliance Method
B. Prescriptive Compliance Method
C. Historic Building Method
D. Relocated Building Method
Rationale: Chapter 5 contains the Prescriptive Compliance Method. It is
one of the principal methods available for qualifying alterations, additions,
and changes of occupancy.
