, Q1. A property owner receives a notice of violation for an unpermitted addition. The
owner argues that the structure is 'grandfathered' because it has existed for 15 years
without complaint. Which principle most directly governs whether the enforcement
action can proceed?
A. Statute of limitations for building code violations
B. Doctrine of laches
C. Continuing violation doctrine
D. Equitable estoppel
Correct Answer: C. Continuing violation doctrine
Rationale: The continuing violation doctrine holds that each day a violation persists
constitutes a new offense, so the passage of time does not bar enforcement. Laches and
equitable estoppel require detrimental reliance and prejudice, which are not automatically
established by mere passage of time. Statutes of limitation typically do not apply to
ongoing code violations.
Why Wrong:
A - Statutes of limitation rarely apply to ongoing building code violations, as each day
is a new violation.
B - Laches requires unreasonable delay causing prejudice, not just existence for 15
years.
D - Equitable estoppel requires affirmative misconduct by the enforcing agency, not
mere inaction.

Enforcement, Ch. 3
Q2. During a rental housing inspection, an officer observes a furnace vent connector
that is corroded and disconnected at the draft hood. The tenant reports intermittent
headaches and nausea. Which immediate action is most appropriate?
A. Issue a notice of violation with 30-day compliance period
B. Post an 'unsafe structure' notice and order immediate disconnect of the furnace
C. Take no action until a licensed HVAC contractor confirms the hazard
D. Refer the matter to the health department only
Correct Answer: B. Post an 'unsafe structure' notice and order immediate disconnect
of the furnace
Rationale: The disconnected vent can cause carbon monoxide (CO) accumulation, which
is an immediate life-safety hazard. Code enforcement officers are authorized to declare the
system unsafe and require immediate disconnection to prevent CO poisoning. Waiting 30
days or referring only to health department would leave the hazard unmitigated.
Why Wrong:
A - A 30-day compliance period is inappropriate for an imminent life-safety hazard.
