A. General Lot Standards.

1. Subdivisions shall comply with development standards per this chapter, including frontage standards, for all existing and newly created lots abutting public streets, private accessways, and private driveways, with the following caveats:

a. A development may instead utilize the single-family infill development option standards per Section 608.F.6 and Table 614.B, column D (except for the density, which is not restricted) if it meets all three of the following conditions:

(1) The development consists solely of single-family dwelling units and allowable accessory uses;

(2) The development is located within the applicable area for the single-family infill development option or the infill development district as depicted on the map provided in Section 608.F.6; and

(3) The development is located in any transect other than T3.

b. All subdivisions must comply with the requirements of the Subdivision Ordinance (Chapter 32 of the City Code), as may be modified by the Subdivision Committee to further the goals of the Walkable Urban Code.

2. All developments adjacent to single-family zoning districts shall follow the same setback and stepback standards as the single-family infill development option (Table 614.B, column D); with additional requirements as follows:

a. Stepback provision shall not exceed maximum 75-foot setback from rear and side property lines for building height before maximum height allowed.

b. For all development abutting a historic preservation designated property or district, a minimum ten-foot landscape setback shall be provided.

c. No stepback provisions or landscape setbacks are required where the development abuts a permanent open space at least 40 feet in depth, such as a wash, preserve, park, existing golf course, or dedicated open space.

3. The minimum side and rear yard setback requirements in Table 1303.1 shall apply to all structures 48 feet height or greater:

**Table 1303.1 Setback Requirements. Buildings Over 48 Feet.**
BUILDING HEIGHT	Rear and side setbacks, if adjacent to the following: R1-10, R1-8, R1-6, and historic preservation properties and districts.

80 feet and above	Minimum 30-foot building setback from property line plus one-foot setback for each two-foot increase in height, up to 75 feet setback.

4. Modifications per Section 1312.

5. Height Restrictions. In no event can the height exceed the airport height limit in accordance with FAA height restrictions.

6. Frontages. Lot lines abutting a right-of-way, private accessway, or private driveway are designated as primary frontage lines or secondary frontage lines as follows:

a. For lots abutting a right-of-way, private accessway, or private driveway along a single lot line, the abutting lot line is designated the primary frontage.

b. For lots abutting multiple rights-of-way, private accessways, or private driveways, primary frontage is designated by the Planning and Development Department, and all remaining frontages are designated secondary frontages.
