Article 5: Development Standards Section 5.9. Building Configuration and Design 5.9.7. Single-Family Attached, Detached and Duplex Design Guidelines

(B) For the purposes of this section, “distinctly different” shall mean that a dwelling must differ from other adjacent and opposing dwellings in at least six of the following ways:

(i) Color variation (not a slight variation of a similar hue, such as beige or pastel);

(ii) Variation in materials;

(iii) Use of distinct variations in roof forms (e.g. gable, hip, shed, mansard, gambrel, flat, or other);

(iv) Variations in the number of building stories by at least one story;

(v) Variation in the amount of habitable space (a minimum distinction of 400 square feet or more);

(vi) A change in the depth of the front setback by 15 feet or more;

(vii) The type and color of roofing material on structures with pitched roofs;

(viii) The orientation of the longest building axis (either parallel, perpendicular; or canted to the street the dwelling faces); or (ix) The primary roof ridgeline orientation (either parallel, perpendicular, canted to the street the dwelling faces).

(2) Single-family Attached Structures

(A) Single-family attached development shall maintain architectural variability from building to building within a development and from unit to unit within a single building. A continuous row of identical or near identical buildings or units within a building along a block shall be prohibited. Each building shall include “distinctly different” front facade elevations within any single phase of the development such that: (i) Each in-line unit in a row of attached single-family dwellings located within a single building includes a front facade comprised of different exterior materials, colors, or architectural features; (ii) Each individual building (comprised of several in-line units in a row) shall be configured such that the overall front facade of one building differs from the overall front facade of each adjacent building (See Figure 5.9.7.B.3.f(2): Architectural Variability.); and (iii) No individual building directly across the street from another building shall have the same overall front facade. (B) For the purposes of this section, “distinctly different” shall mean that a building comprised of multiple in-line units must differ from other adjacent and opposing buildings containing multiple in-line units in at least five of the following ways:

(i) Variation in structure height of at least one story or more;

(ii) Variation in primary roof form (e.g., gabled, hip, flat, or a combination of multiple distinct roof slopes or planes);

(iii) Variation in building footprint by at least 1,000 square feet or more;

(iv) The presence or absence of attached garages;

(v) One-car versus two-car garage;

(vi) Variation in garage orientation;

(vii) Variation in exterior cladding material over at least 75 percent of the building’s area; or
