10. Wherever a rear lot line abuts an alley, one-half (½) of the right-of-way width of the alley may be counted toward the required minimum rear setback; provided, however, that the portion of the minimum rear setback actually on the lot itself shall not be so reduced to less than ten (10) feet. Also, see Section 17.108.130 for allowed projections into setbacks.

11. When a rear lot line in the RU-4 or RU-5 Zones is adjacent to an RH, RD, or RM Zone, the required rear setback for both Residential and Nonresidential Facilities is ten (10) feet. When a rear lot line of a lot in

these zones is not adjacent to an RH, RD, or RM Zone, the required rear setback is ten (10) feet for Residential Facilities and there is no required setback for Nonresidential Facilities.

12. This height is only required for new principal buildings with ground floor Nonresidential Facilities, and is measured from the sidewalk grade to the second story floor.

13. This regulation only applies to new Residential Facilities and ground floor living space located within fifteen (15) feet of a street frontage.

14. Buildings in the RU Zones shall have a thirty (30) foot maximum height at the setback line associated with any rear or interior side lot line that abut a lot in an RH, RD, or RM Zone; if the principal building on the abutting lot has a height of thirty (30) feet or less, this maximum height shall increase one (1) foot for every foot of distance from this setback line. If the principal building on the abutting lot has a height of greater than thirty (30) feet, the maximum height shall increase two (2) feet for every foot away from the applicable setback line (see Illustration for Table 17.19.03 [Additional Regulation 14], below). Also, see Section 17.108.030 for allowed projections above height limits and Section 17.108.020 for increased height limits in certain situations.

18. For the new construction of principal buildings in the RU-4 and RU-5 Zones, access to parking and loading facilities through driveways, garage doors, or other means shall not be from the principal street when alternative access is feasible from another location such as a secondary frontage or an alley. Where this is not feasible, every reasonable effort shall be made to share means of vehicular access with abutting properties. Open parking areas shall not be located between the sidewalk and a principal building.

19. Usable open space is only required on lots with two (2) or more dwelling units, excluding any permitted Accessory Dwelling Units. Each one (1) square foot of private usable open space equals two (2) square feet towards the total usable open space requirement, except that actual group space shall be provided in the minimum amount specified in the table per dwelling unit, excluding any permitted Accessory Dwelling Units. All usable open space shall meet the standards contained in Chapter 17.126.

20. See Section 17.103.085 for setback and separation requirements for Vehicular Residential Facilities.

21. For developments involving the creation of new units on two (2) or more adjoining parcels under the same ownership, there is no minimum interior side setback required between those new units.

Additional Regulations for Table 17.19.04:

1. The maximum height within ten (10) feet of the front property line is either the height limit on the subject lot shown in the above table or the height maximum for the height area of the parcel directly across the principal street, whatever is less (see Illustration for Table 17.19.04 [Additional Regulation 1], below).

Illustration for Table 17.19.04 [Additional Regulation 1] *for illustration purposes only

2. Buildings in the RU Zones shall have a thirty (30) foot maximum height at the setback line along any rear or interior side lot line that abuts a lot in an RH, RD, or RM Zone; if the principal building on the abutting lot has a height of thirty (30) feet or less, this maximum height may increase one (1) foot for every foot of distance away from this setback line. If the principal building on the abutting lot has a height of greater than thirty (30) feet, the maximum height shall increase two (2) feet for every foot away from the applicable setback line. Also, see Section 17.108.030 for allowed projections above height limits and Section 17.108.020 for increased height limits in certain situations.

3. This minimum height requirement only applies to the new construction of a principal building that is located on parcels adjacent to a street right-of-way that is one hundred (100) feet wide or more. Buildings constructed to accommodate Essential Service, Utility and Vehicular, or Extensive Impact Civic Activities are exempted from the height minimum regulation. The allowed projections into the height limits contained in Section 17.108.030 are not counted towards the height minimum.

4. See Chapter 17.107 for affordable and senior housing incentives. See Section 17.103.080 and Chapter 17.88 for regulations regarding permitted Accessory Dwelling Units.
