1. All setbacks shall be measured at right angles from the designated property line to the building or structure, and the setback line shall be drawn parallel to and at the specified distance from the corresponding front, side, or rear property line (See Figure 3-2, Setback Measurements).

2. Front Setback. A front setback shall be measured at right angles from the nearest point on the public right-of-way at the front of the parcel (or edge of access easement on a private street) to the nearest point of the wall of the structure.

3. Side Setback, Interior. A side setback shall be measured at right angles from the nearest point on the interior side property line of the parcel to the nearest point of the wall of the structure, establishing a setback line parallel to the interior side property line, which extends between the front and rear setbacks.

4. Street Side Setback. A street side setback shall be measured from the nearest point on the side property line coterminous with the street side public right-of-way, establishing a setback line parallel to the public street right-of-way. The street side setback extends between the front setback and the rear property line.

5. Rear Setback. A rear setback shall be measured at right angles from the nearest point on the rear property line of the parcel to the nearest point of the wall of the structure, establishing a setback line parallel to the rear property line.

1. Where a front or street side “build-to-line” requirement is established by the applicable zoning district, a proposed structure shall instead comply with the build-to-line requirement.

A build-to-line specifies the required location of new structures with respect to the street frontages of a site, so that proposed buildings will effectively assist in shaping the public space of streets and enhance the pedestrian experience.

2. Front Setback Averaging. Notwithstanding any of the minimum front yard setbacks required in all of the residential districts, the front yard minimum setback specified in these districts may be reduced where lots comprising forty percent or more of the frontage on one side of a street between intersecting streets are developed with buildings having an average front yard with a variation of not more than ten feet.

In such cases, no building newly erected or structurally altered may project beyond the average front yard line established by the existing buildings. In making this determination, buildings located more than thirty-five feet from the front property line or buildings facing a side street on a corner lot shall not be counted. In no case shall any building or structure be located within any planned future right-of-way.
