VERIFIED ANSWERS
Question 1
The purpose of this code is to establish
_________ requirements to safeguard
the public safety, health and general
welfare.
Correct Answer
minimum
Rationale:
The word "minimum" is chosen because it implies the lowest possible standard necessary to ensure public safety, health, and welfare, thereby
preventing harm or risk. In regulatory or safety contexts, "minimum" requirements are often the bare essentials required to prevent adverse
outcomes, making it a fitting choice to safeguard the public.
Question 2
Where, in any specific case, different
sections of this code specify different
materials, methods of construction or
other requirements, the most _________
shall govern.
Correct Answer
restrictive
Rationale:
The word "restrictive" is used in this context because it refers to a provision that imposes limitations or restrictions on what can be done,
making it the most limiting or restrictive option among the alternatives. In this specific case, the "most restrictive" option would govern,
ensuring that, if different sections of the code specify different requirements, the most limiting one would take precedence.

,Question 3
Where a referenced code or standard
includes subject matter that is within
the scope of the IRC, the provisions of
the _________ shall take precedence.
Correct Answer
IRC
Rationale:
The IRC (International Residential Code) is the correct answer because it is a model code that takes precedence over referenced codes or
standards when the subject matter falls within its scope, as specified in the code itself. This precedence is based on the code's hierarchical
structure, where the IRC serves as the overarching authority, superseding other referenced codes or standards when applicable.
Question 4
An alternative material or method shall
be approved where the proposed
design is _________ and complies with
the _________ of the code.
Correct Answer
satisfactory
intent
Rationale:
The word "satisfactory" is correct because it implies that the proposed design meets the minimum requirements or standards set by the code,
indicating that it is sufficient or acceptable. This term is often used in code compliance to denote that a design or method meets the essential
criteria, making it a suitable choice in this context.
Question 5
Compliance with the specific _________
-based provisions of the International
Codes in lieu of specific requirements
of the IRC shall be permitted as an
alternative.
Correct Answer
performance
Rationale:
This sentence is referring to the specific performance-based provisions of the International Codes, which means it's discussing the standards
and criteria used to measure the effectiveness or quality of a building or system. The reason "performance" is the correct answer is that
performance-based provisions focus on the desired outcome or result of a building or system, rather than specific details or requirements,
allowing for flexibility and innovation in design and construction.

,Question 6
A permit is not required for one-story
detached accessory structures,
provided that the floor area does not
exceed _________ square feet.
Correct Answer
200
Rationale:
The key concept here is that a permit is required for accessory structures that exceed a certain threshold, implying a maximum size limit. By
stating "does not exceed," the regulation is establishing a cap on the floor area, meaning that any structure up to a certain size does not
require a permit.
Question 7
Fences that are _________ feet or less in
height do not require permits.
Correct Answer
7
Rationale:
The correct answer is "7" because many jurisdictions have established a height limit of 7 feet or less for fences that do not require permits,
allowing for more flexibility in residential areas while still maintaining property boundaries. This standard height limit is often set to balance the
need for property owners to have control over their property with the need for local authorities to regulate and enforce building codes and
zoning regulations.
Question 8
A permit is not required for the
replacement of branch circuit
overcurrent devices (breakers) of the
required capacity in the same location
(within a panel).
Correct Answer
True
Rationale:
The question hinges on the National Electrical Code (NEC) article 210.8(A), which allows replacement of branch circuit overcurrent devices in
the same location without requiring a permit. This exemption is based on the assumption that the replacement does not alter the electrical
system's overall configuration or safety, thus eliminating the need for a permit.

, Question 9
Unattached decks not exceeding
_________ square feet in area, that are
not more than _________ inches above
grade, do not require a permit.
Correct Answer
200
30
Provided the decks do not serve the exit door required by Section R311.4.
Rationale:
The given answer is correct because it directly corresponds to the specific exemption criteria outlined in the building code, where unattached
decks that satisfy certain conditions are exempt from permit requirements. This exemption is based on the deck's area and height relative to
grade, which are key factors in determining the need for a permit, and the provided values align with this criteria.
Question 10
Where equipment replacements and
repairs must be performed in an
emergency situation, the permit
application shall be submitted within
the _________ _________ business day.
Correct Answer
next working
...to the building official.
Rationale:
The correct answer is "next working day" because it refers to the next calendar day that is not a weekend or holiday, when business operations
typically resume. This ensures that the permit application is submitted in a timely manner, while also allowing for realistic expectations in
emergency situations.
Question 11
An application for a permit for any
proposed work shall be deemed to have
been abandoned _________ days after
the date of filing.
Correct Answer
180
180 days also applies to extensions.
Rationale:
The correct answer is based on the assumption that "180 days also applies to extensions" implies that any additional time granted for filing due
to extensions should still be subject to the 180-day initial timeframe. This assumption is likely derived from the principle that extensions should
not indefinitely postpone the abandonment deadline, thereby maintaining the original 180-day timeframe as the overall limit.
