,Q1. A four-story office building with a fire-resistance-rated exterior wall located 15 feet from the
property line has unprotected openings in that wall. The building is not sprinklered. What is the
maximum allowable area of individual unprotected openings per floor, assuming the openings are
not limited by the percentage of wall area?
A. No limit if the building is of Type II construction
B. 25% of the wall area per floor
C. Unprotected openings are not permitted at this distance
D. The area is determined by Table 705.8, based on the fire separation distance and the percentage of
openings allowed
Correct Answer: D. The area is determined by Table 705.8, based on the fire separation distance
and the percentage of openings allowed
Rationale: IBC Table 705.8 (formerly Table 704.8) specifies the maximum area of unprotected openings
based on fire separation distance and the percentage of openings in the wall area. For a 15-foot
separation, the table allows a certain percentage (e.g., 25% for certain distances). Option A is incorrect
because construction type does not override the table. Option B is only correct if the table specifies 25%
at that distance, but the correct answer is the table itself. Option C is false because unprotected openings
are permitted at 15 feet with limitations.
Why Wrong:
A - Construction type does not automatically remove limits; Table 705.8 governs.
B - The exact percentage is not always 25%; it depends on the table.
C - Unprotected openings are permitted at 15 feet with limits per Table 705.8.
Reference: IBC 2024, Section 705.8, Table 705.8
Q2. A mixed-use building contains a Group A-3 assembly occupancy on the first floor and Group
R-2 dwelling units above. The building is fully sprinklered. The assembly occupancy has an
occupant load of 300. What is the minimum required width of the exit access stairway serving the
assembly area if it is a single stairway?
A. 44 inches
B. 56 inches
C. 60 inches
D. The stair width must be calculated based on the occupant load and the stairway's capacity factor
Correct Answer: D. The stair width must be calculated based on the occupant load and the
stairway's capacity factor
Rationale: The required stair width is determined by multiplying the occupant load by the capacity factor
(0.3 inches per occupant for stairs, per IBC Table 1005.5.1). For 300 occupants, 300 × 0.3 = 90 inches.
However, the minimum width per Section 1011.2 is 44 inches, so the required width is 90 inches, not a
fixed dimension. Options A, B, and C are arbitrary numbers that do not reflect the calculation.
Why Wrong:
A - 44 inches is the minimum, but the occupant load requires a greater width.
B - 56 inches is not derived from the standard calculation.
C - 60 inches is not derived from the standard calculation.

, Q3. An existing two-story building is undergoing a change of occupancy from a warehouse (Group
S-1) to a retail store (Group M). The building is of Type IIIB construction and is not sprinklered.
Which of the following is the most significant code requirement that must be addressed?
A. Increase the fire-resistance rating of the exterior walls to 2 hours
B. Provide a fire-resistance-rated separation between the two stories
C. Install an automatic sprinkler system throughout the building
D. Upgrade the means of egress to meet Group M requirements
Correct Answer: C. Install an automatic sprinkler system throughout the building
Rationale: Group M occupancies with an occupant load of 100 or more require sprinklers per IBC
Section 903.2.7. The change of occupancy triggers compliance with current code for fire protection.
Option A is incorrect because exterior wall ratings are based on fire separation distance, not occupancy
alone. Option B is not required for Group M unless the building exceeds certain height/area limits.
Option D is also required, but the most significant and costly is the sprinkler requirement.
Why Wrong:
A - Exterior wall rating depends on fire separation distance, not just occupancy change.
B - Fire separation between stories is not typically required for Group M unless the building is over
3 stories.
D - Egress upgrades are necessary but less impactful than sprinklers in this scenario.
Reference: IBC 2024, Sections 903.2.7, 3405
Q4. A building official is reviewing plans for a new 10-story hotel. The building has a basement level
used for mechanical equipment and storage. Which of the following statements regarding smoke
control systems is correct?
A. A smoke control system is not required because the building is fully sprinklered
B. A smoke control system is required for the basement if the basement exceeds 2,000 square feet
C. A smoke control system is required for the entire building if the floor level of the highest occupied
story is more than 75 feet above the lowest level of fire department vehicle access
D. A smoke control system is only required for atriums, not for basements
Correct Answer: C. A smoke control system is required for the entire building if the floor level of
the highest occupied story is more than 75 feet above the lowest level of fire department vehicle
access
Rationale: IBC Section 909.2 requires a smoke control system for buildings with a floor level of the
highest occupied story more than 75 feet above the lowest level of fire department vehicle access. Option
A is false because sprinklers do not eliminate the requirement. Option B is incorrect; basement smoke
control is not triggered by area alone. Option D is false because smoke control may be required in other
areas.
Why Wrong:
A - Sprinklers do not exempt a building from smoke control requirements.
B - Basement smoke control requirements are based on occupancy and height, not just area.
D - Smoke control may be required for basements, large spaces, and other areas.

property line has unprotected openings in that wall. The building is not sprinklered. What is the
maximum allowable area of individual unprotected openings per floor, assuming the openings are
not limited by the percentage of wall area?
A. No limit if the building is of Type II construction
B. 25% of the wall area per floor
C. Unprotected openings are not permitted at this distance
D. The area is determined by Table 705.8, based on the fire separation distance and the percentage of
openings allowed
Correct Answer: D. The area is determined by Table 705.8, based on the fire separation distance
and the percentage of openings allowed
Rationale: IBC Table 705.8 (formerly Table 704.8) specifies the maximum area of unprotected openings
based on fire separation distance and the percentage of openings in the wall area. For a 15-foot
separation, the table allows a certain percentage (e.g., 25% for certain distances). Option A is incorrect
because construction type does not override the table. Option B is only correct if the table specifies 25%
at that distance, but the correct answer is the table itself. Option C is false because unprotected openings
are permitted at 15 feet with limitations.
Why Wrong:
A - Construction type does not automatically remove limits; Table 705.8 governs.
B - The exact percentage is not always 25%; it depends on the table.
C - Unprotected openings are permitted at 15 feet with limits per Table 705.8.
Reference: IBC 2024, Section 705.8, Table 705.8
Q2. A mixed-use building contains a Group A-3 assembly occupancy on the first floor and Group
R-2 dwelling units above. The building is fully sprinklered. The assembly occupancy has an
occupant load of 300. What is the minimum required width of the exit access stairway serving the
assembly area if it is a single stairway?
A. 44 inches
B. 56 inches
C. 60 inches
D. The stair width must be calculated based on the occupant load and the stairway's capacity factor
Correct Answer: D. The stair width must be calculated based on the occupant load and the
stairway's capacity factor
Rationale: The required stair width is determined by multiplying the occupant load by the capacity factor
(0.3 inches per occupant for stairs, per IBC Table 1005.5.1). For 300 occupants, 300 × 0.3 = 90 inches.
However, the minimum width per Section 1011.2 is 44 inches, so the required width is 90 inches, not a
fixed dimension. Options A, B, and C are arbitrary numbers that do not reflect the calculation.
Why Wrong:
A - 44 inches is the minimum, but the occupant load requires a greater width.
B - 56 inches is not derived from the standard calculation.
C - 60 inches is not derived from the standard calculation.

, Q3. An existing two-story building is undergoing a change of occupancy from a warehouse (Group
S-1) to a retail store (Group M). The building is of Type IIIB construction and is not sprinklered.
Which of the following is the most significant code requirement that must be addressed?
A. Increase the fire-resistance rating of the exterior walls to 2 hours
B. Provide a fire-resistance-rated separation between the two stories
C. Install an automatic sprinkler system throughout the building
D. Upgrade the means of egress to meet Group M requirements
Correct Answer: C. Install an automatic sprinkler system throughout the building
Rationale: Group M occupancies with an occupant load of 100 or more require sprinklers per IBC
Section 903.2.7. The change of occupancy triggers compliance with current code for fire protection.
Option A is incorrect because exterior wall ratings are based on fire separation distance, not occupancy
alone. Option B is not required for Group M unless the building exceeds certain height/area limits.
Option D is also required, but the most significant and costly is the sprinkler requirement.
Why Wrong:
A - Exterior wall rating depends on fire separation distance, not just occupancy change.
B - Fire separation between stories is not typically required for Group M unless the building is over
3 stories.
D - Egress upgrades are necessary but less impactful than sprinklers in this scenario.

Q4. A building official is reviewing plans for a new 10-story hotel. The building has a basement level
used for mechanical equipment and storage. Which of the following statements regarding smoke
control systems is correct?
A. A smoke control system is not required because the building is fully sprinklered
B. A smoke control system is required for the basement if the basement exceeds 2,000 square feet
C. A smoke control system is required for the entire building if the floor level of the highest occupied
story is more than 75 feet above the lowest level of fire department vehicle access
D. A smoke control system is only required for atriums, not for basements
Correct Answer: C. A smoke control system is required for the entire building if the floor level of
the highest occupied story is more than 75 feet above the lowest level of fire department vehicle
access
Rationale: IBC Section 909.2 requires a smoke control system for buildings with a floor level of the
highest occupied story more than 75 feet above the lowest level of fire department vehicle access. Option
A is false because sprinklers do not eliminate the requirement. Option B is incorrect; basement smoke
control is not triggered by area alone. Option D is false because smoke control may be required in other
areas.
Why Wrong:
A - Sprinklers do not exempt a building from smoke control requirements.
B - Basement smoke control requirements are based on occupancy and height, not just area.
D - Smoke control may be required for basements, large spaces, and other areas.
