,Q1. During a full lead-based paint risk assessment in a pre-1978 DC row house, an
XRF analyzer shows 5.0 mg/cm² lead on a window sill in a bedroom occupied by a
pregnant tenant. The tenant states the sill paint is intact. Which action is most
appropriate under the DC Lead Hazard Prevention and Elimination Act?
A. Classify as a lead-contaminated dust lead hazard and require immediate soil
remediation
B. Document as a lead-based paint hazard and order abatement within 30 days
C. No violation exists because paint is intact; recommend voluntary dust wipe
sampling
D. Treat as a lead-based paint hazard only if the paint is peeling or damaged
Correct Answer: B. Document as a lead-based paint hazard and order abatement
within 30 days
Rationale: Under DC law, any lead-based paint on a friction surface in a dwelling unit
occupied by a pregnant person or child under 6 is a defined hazard regardless of
condition. Option B correctly identifies the regulatory trigger. Option A confuses dust and
paint hazards. Option C is incorrect because intact paint on a friction surface is still a
hazard. Option D applies a condition-based standard that is preempted by DC's stricter
law.
Why Wrong:
A - The scenario involves paint on a surface, not dust; soil remediation is not
indicated.
C - Intact paint on a friction surface in a unit with a pregnant occupant meets the DC
definition of a lead-based paint hazard.
D - DC law does not require the paint to be damaged to constitute a hazard for friction
surfaces in sensitive occupancy.
Reference: Title 14 DCMR Ch. 8 (Lead Hazard Prevention); DC Code § 8-231.01 et seq.
Q2. During an inspection of a four-story multifamily building, you observe the
following violations: (1) a missing smoke detector in a second-floor hallway, (2) a
cracked window pane in a third-floor apartment, (3) a leaking toilet with standing
water on the bathroom floor, and (4) an improperly secured handrail on the main
stairway. According to DC housing code severity classifications, which violation
requires the most immediate corrective action?
A. Missing smoke detector
B. Cracked window pane
C. Leaking toilet with standing water
D. Improperly secured handrail
Correct Answer: A. Missing smoke detector
Page 3
, Rationale: Missing smoke detectors are considered a critical life-safety violation under 14
DCMR 701 because they directly threaten occupant survival in a fire. While the other
violations are serious, the handrail and leaking toilet are classified as serious or
moderate, and the cracked pane is minor. Immediate abatement orders are typically issued
for critical violations.
Why Wrong:
B - A cracked window pane is a minor violation and does not pose an imminent life
safety risk.
C - A leaking toilet with standing water is a serious health/sanitation issue but not as
time-critical as fire safety.
D - An improperly secured handrail is a serious violation but considered less urgent
than a missing smoke detector in terms of immediate life threat.

Q3. In a 1920s row house, you find ungrounded two-wire receptacles (Type A)
throughout the dwelling. The owner recently installed GFCI-protected receptacles in
the kitchen and bathroom but left other rooms unchanged. There is no evidence of a
grounding conductor in any receptacle box. Which statement accurately reflects the
required corrective action under the DC Electrical Code (2017 NEC as amended)?
A. All non-GFCI receptacles must be replaced with GFCI-protected receptacles or a
GFCI breaker must be installed
B. No action required because GFCI protection in wet locations provides adequate
safety
C. A grounding conductor must be run to all ungrounded receptacles within two years
D. Only receptacles within 6 feet of a sink require GFCI protection; other receptacles
are compliant as original
Correct Answer: A. All non-GFCI receptacles must be replaced with GFCI-protected
receptacles or a GFCI breaker must be installed
Rationale: The DC Electrical Code requires replacement receptacles in non-grounded,
non-conducting enclosures to be GFCI-protected or replaced with a GFCI receptacle. The
exception for two-wire systems mandates GFCI protection for any new or replacement
outlet. Option B incorrectly assumes that local GFCI suffices; all outlets must be upgraded
to reduce shock risk. Options C and D are not compliant with code.
Why Wrong:
B - GFCI protection in wet locations does not protect other outlets; the entire branch
lacks grounding and must be GFCI-protected at the first outlet or via breaker.
C - Running a grounding conductor is not the required method; GFCI protection is the
approved alternative.
D - The scope of GFCI requirements is broader for replacement outlets in ungrounded
systems.
