§ 2.4 SF District Regulations.

2.4.1

References.

When the provisions of this zoning ordinance refer to “single-family” or “SF” districts, they are referring to SF-1, SF-2, SF-3, and SF-4 districts.

2.4.2

Lot of Record Prior to Adoption.

The minimum dimensional and intensity standards for the SF districts shall be in accordance with Section 2.4, except for any lot that was an official lot of record before the effective date specified in Section 1.3. See also the nonconforming lot provisions of Section 10.3.2.

2.4.3

Lot and Building Zones.

For the purpose of presenting SF lot and building regulations, lots are divided into a series of smaller segments or “zones,” as described in this subsection and illustrated in Figure 2-1.

Overall Lot.

Some regulations apply to the entire lot. These regulations are referred to as “overall lot” regulations and are presented in Section 2.4.4.

Street-Yard Zone.

Street-yard zone regulations govern the area between any lot line abutting a street right-of-way and the minimum front or street-side setback line (see Section 2.4.5).

Main-House Zone.

The main-house zone accommodates the greatest building mass. The zone extends from the back of the street-yard zone rearward to the mid-lot zone (see Section 2.4.6).

Mid-Lot Zone.

The mid-lot zone lies immediately at the back of the main-house zone and extends rearward to the rear lot zone. Portions of the principal building may be located in this zone, but the regulations are more stringent than in the main-house zone (see Section 2.4.7).

Rear-Lot Zone.

The rear-lot zone covers the rearmost portion of the lot, typically abutting an alley. The rear-lot zone extends from the rear lot line forward for a distance of 40 feet (see Section 2.4.8).

2.4.9

Front Facade Articulation

Purpose and Applicability.

The front facade articulation provisions of this subsection are intended to encourage multiple planes on the front street-facing facade of houses. The provisions apply to houses in SF districts.

Permitted Facade Encroachments.

Up to 60% of the width of a house’s front facade may encroach into (forward of) the required front setback by up to 2 feet if the remaining portion of the house’s front facade is set back at least one foot more than the minimum front setback. One example of this front setback encroachment allowance is illustrated in Figure 2-2.

If a portion of a house’s front facade is set back 3 feet or more beyond the minimum front street setback, the main-house zone is allowed to extend up to 3 feet into the mid-lot zone or the rear-lot zone when no mid-lot zone exists. The width of the house’s main-house extension may not exceed the width of the portion of the front facade that is set back 3 feet or more beyond the minimum front street setback. Permitted rear yard encroachments are illustrated in Figure 2-3.
