Unified Development Ordinance, 25th Supplement, December 2022

CHAPTER 1. ​INTRODUCTORY PROVISIONS | Article 1.5. Measurement, Exceptions & General Rules of Applicability

C. General Requirements 1. On corner lots, building façade fronting each street must be placed within the intersecting build-to range for each street. Amenity area provided in accordance with Section 1.5.6.C.4. may be used to satisfy this requirement. 2. With the exception of parking areas, all structures and uses customarily allowed on the lot are permitted in the build-to area. 3. When any of the items listed below are generally perpendicular to the right of-way and located within the applicable build-to range, lot width shall be reduced by the width of the impediment for the purposes of calculating build-to percentage. To qualify, a perpendicular impediment must reduce the build-to range to less than 10’ as detailed below. For example, a 100’ wide lot with a 20’ wide perpendicular easement would be considered an 80’ wide lot when calculating build-to percentage.

maximum setback range from the edge of the proposed or existing right-of way, whichever is greater. 2. The required percentage specifies the amount of the lot width, site width, or blockface width in the case of townhouses, that must be occupied by front building façade within the build-to range, measured based on the width of the building divided by the width of the site, lot, or townhouse blockface, whichever applies. 3. There are 2 types of build-to -- primary street build-to and side street build to. Through lots are considered to have at least 1 primary street build-to. The designation of the primary street build-to shall follow the rules of Sec. 1.5.4.C. No build-to is required on the non-primary street frontage of a through lot.

B. Intent 1. The build-to is intended to provide a range for building placement that strengthens the street edge along the right-of-way, establishing a sense of enclosure by providing spatial definition adjacent to the street. 2. The building edge can be supplemented by architectural elements and certain tree plantings aligned in a formal rhythm. The harmonious placement of buildings to establish the street edge is a principal means by which the character of an area or district is defined. 3. The build-to range is established to accommodate some flexibility in specific site design while maintaining the established street edge.

When any of the items listed below are generally parallel to the right-of-way, located within the build-to range, and reduce the build-to range to less than 5', then the build-to range shall be reduced by 50% and measured from the edge of the impediment. For example, a lot with a 17’ parallel easement and initial build-to range of 0'/20' shall be considered to have a new build-to range of 17’/27’.
