PART I: THE PRIMER
Mastering this elite test bank forges a baseline of absolute regulatory certainty, allowing the
architectural practitioner to navigate the District of Columbia's unique federal-local legislative
matrix flawlessly. By internalizing these rigid statutory constraints, your academic mastery
directly translates to averted liabilities, expedited permit approvals, and high-level professional
competence in one of the world's most heavily regulated jurisdictions.

PART II: THE ELITE TEST BANK
Q1: A commercial building is proposed on a 90-foot-wide business street. Under the Height of
Buildings Act of 1910, what is the MAXIMUM permitted height? A) 90 feet B) 100 feet C) 110
feet D) 130 feet
● The Answer: C (110 feet)
● Distractor Analysis:
○ A is incorrect: Confuses street width with the allowed height formula.
○ B is incorrect: Applies an invalid "+10" metric.
○ D is incorrect: Identifies the absolute commercial cap, ignoring the specific
mathematical formula for a 90-foot street.
The Mentor's Analysis: The Height Act strictly mathematically limits commercial buildings. The
immediate priority is applying the primary formula: street width + 20 feet. Professional/Academic
Intuition: Commercial height always equals street width plus 20 feet, capped at 130 feet.
Q2: A residential flat is designed on a 75-foot-wide residence street. Under the Height Act, what
is the MAXIMUM allowable height to the highest ceiling joists? A) 65 feet B) 75 feet C) 85 feet
D) 95 feet
● The Answer: A (65 feet)
● Distractor Analysis:
○ B is incorrect: Equals the street width without applying the required residential
deduction.
○ C is incorrect: This is the maximum absolute cap for the roof/parapet, not the
formula output.
○ D is incorrect: Applies the commercial formula (+20) to a residential street.
The Mentor's Analysis: Residential streets face harsher federal restrictions to preserve light and
air. The immediate priority is deducting from the street width. Professional/Academic Intuition:
Residential height equals street width minus 10 feet.
Q3: A corner lot building faces a 110-foot-wide business avenue and a 60-foot-wide residential
street. From which point MUST the building's height be measured under the Height Act? A) The
midpoint of the 60-foot street. B) The sidewalk opposite the middle of the 110-foot avenue front.
C) The lowest topological elevation of either sidewalk. D) The highest topological elevation of
the rear alley.
● The Answer: B (The sidewalk opposite the middle of the 110-foot avenue front.)
● Distractor Analysis:
○ A is incorrect: The law allows measurement from the front that permits the greater
height.
○ C is incorrect: Calculates minimum grade, irrelevant to the Height Act's specific
measurement datum.
, ○ D is incorrect: Alleys do not determine Height Act frontages.
The Mentor's Analysis: The Height Act favors the developer on corner lots. The immediate
priority is establishing the widest contiguous street. Professional/Academic Intuition: Always
measure from the sidewalk opposite the middle of the front that permits the greatest
height.
Q4: A historic landmark requires minor, in-kind roof repairs. Which entity FIRST holds the
authority to administratively approve this work? A) The Commission of Fine Arts (CFA) B) The
Historic Preservation Review Board (HPRB) C) The Historic Preservation Office (HPO) D) The
Mayor's Agent
● The Answer: C (The Historic Preservation Office (HPO))
● Distractor Analysis:
○ A is incorrect: The CFA reviews Georgetown projects, not general DC minor
repairs.
○ B is incorrect: The HPRB delegates minor work downward to staff.
○ D is incorrect: The Mayor's Agent acts as an appellate body.
The Mentor's Analysis: Efficiency in preservation requires understanding delegation. The
immediate priority is securing staff-level sign-off. Professional/Academic Intuition: The HPO
staff clears minor, in-kind work administratively without a board hearing.
Q5: A client wishes to demolish a contributing structure in a Historic District. Which body MUST
review this major application? A) The Advisory Neighborhood Commission (ANC) exclusively B)
The Historic Preservation Review Board (HPRB) C) The Department of Buildings (DOB) alone
D) The Board of Zoning Adjustment (BZA)
● The Answer: B (The Historic Preservation Review Board (HPRB))
● Distractor Analysis:
○ A is incorrect: ANCs have "great weight" but no statutory review authority.
○ C is incorrect: DOB cannot issue the permit until preservation review is complete.
○ D is incorrect: BZA handles zoning variances.
The Mentor's Analysis: Demolition of historic fabric triggers maximum scrutiny. The immediate
priority is formal board review. Professional/Academic Intuition: Substantial alterations and
demolitions mandate HPRB review.
Q6: A property is located within the Georgetown Historic District. Which federal entity possesses
statutory design review authority over this project? A) The National Capital Planning
Commission (NCPC) B) The Commission of Fine Arts (CFA) C) The Architect of the Capitol
(AOC) D) The Department of Energy and Environment (DOEE)
● The Answer: B (The Commission of Fine Arts (CFA))
● Distractor Analysis:
○ A is incorrect: NCPC handles federal buildings, not Georgetown private properties.
○ C is incorrect: AOC governs Capitol grounds exclusively.
○ D is incorrect: DOEE governs environmental metrics, not aesthetics.
The Mentor's Analysis: Georgetown is a unique federal carve-out. The immediate priority is
federal aesthetic compliance. Professional/Academic Intuition: Georgetown projects always
require CFA approval before permit issuance.
Q7: Under Title 11 DCMR, a property in an R-3 (Residential) zone is undergoing a substantial
addition. What is the Green Area Ratio (GAR) requirement? A) 0.3 GAR B) 0.4 GAR C) 0.6
GAR D) GAR is not applicable.
● The Answer: D (GAR is not applicable.)
● Distractor Analysis:
○ A is incorrect: 0.3 applies to PDR/Commercial zones.
