Q1. What defines a "Major Building" according to A-1001.1 of
the Philadelphia Administrative Code?
A) Buildings taller than 5 stories
B) Buildings with a total area of more than 20,000 square feet
C) Buildings that are more than 3 stories high, more than 40 feet
tall, or cover 10,000 square feet or more
D) All buildings in the commercial district

Rationale: A Major Building is specifically defined by the
Philadelphia Code as exceeding 3 stories, 40 feet in height, OR
10,000 square feet of lot space. Meeting any one of these
,Page 2 of 137
thresholds classifies the structure as Major, which generally
requires a Class A license .
Q2. What is the maximum height for a building to be considered
for Class B demolition if it is not designated as a Major Building?
A) 30 feet
B) 40 feet
C) 50 feet
D) 60 feet
Answer: B
Rationale: Buildings not designated as Major Buildings and
intended for Class B demolition must be no more than 40 feet in
height. The 40-foot demarcation is a key threshold between
Class B and Class A licensing .
Q3. A client requests a bid to demolish a single-story warehouse
that is 35 feet tall and covers 9,500 square feet of lot space. Is
this within the scope of a Class B Demolition Contractor license?
,Page 3 of 137
A) No, because it is a commercial building
B) Yes, because it is under 40 feet tall and under 10,000 square
feet
C) No, because it exceeds 5,000 square feet
D) Yes, because it is only one story
Answer: B
Rationale: Class B demolition covers buildings that are NOT
"Major Buildings." Since this warehouse is under the 40-foot
height limit (35 ft) and under the 10,000 sq ft threshold (9,500
sq ft), it qualifies for Class B scope .
Q4. For a building to be classified under Class B demolition,
what is the maximum lot space it may cover?
A) 5,000 square feet
B) 7,500 square feet
C) Less than 10,000 square feet
D) 12,000 square feet
, Page 4 of 137
Answer: C
Rationale: The Major Building threshold is 10,000 square feet or
more. Therefore, for Class B eligibility, the building must cover
less than 10,000 square feet of lot space. If it covers 10,000 sq
ft or more, it is a Major Building requiring Class A oversight .
Q5. The Department of Licenses and Inspections (L&I) issues the
Demolition Class B contractor license. What is their primary role?
A) Issuing building permits only
B) Enforcing the Philadelphia Code and issuing demolition
licenses
C) Managing citywide traffic control
D) Overseeing environmental remediation
Answer: B
Rationale: The Department of Licenses and Inspections (L&I) is
responsible for issuing demolition contractor licenses and
enforcing the Philadelphia Code .
