4. See Section 17.103.080 and Chapter 17.88 for development standards applicable to permitted Accessory Dwelling Units.

5. In the RD Zone, proposals requiring Regular Design Review approval may only be granted upon determination that the proposal conforms to the Regular Design Review criteria set forth in the design review procedure in Chapter 17.136 and to all of the following additional design review criteria:

a. That the site design and landscaping and the scale, height, length and width, bulk, coverage, and exterior treatment of structures are in harmony with facilities on nearby lots;

b. That the design and site planning of the buildings, open areas, parking and service areas, and other facilities provide a convenient, attractive, and functional living environment; and that paths, stairways, accessways, and corridors are designed to ensure privacy.

6. If adjacent lots abutting the side lot lines of the subject lot both contain principal Residential Facilities that have front setbacks with a depth of less than the minimum required in this Chapter, the minimum front setback shall be reduced for buildings and other structures on the subject lot up to a line parallel to the front lot line and extended from the most forward projection of the principal Residential Facility on the adjacent lots having the deeper front setback depth. In the case of a corner lot, or lot that has one or more vacant parcels next to it, this same principal shall apply if the nearest non-vacant lots to each side of a corner lot, or to each side of a lot that has one or more vacant parcels next to it, have less than the minimum required front setback in this Chapter (see Illustration for Table 17.15.03 [Additional Regulation 6], below).

Illustration for Table 17.15.03 [Additional Regulation 6]
*for illustration purposes only

7. In the RD Zone, the minimum front setback depth otherwise required by the applicable individual zone regulations shall be reduced to five (5) feet on any lot with a street-to-setback gradient that exceeds twenty percent (20%), provided, however, that the distance from garage or carport elevation containing one or more vehicular entries to the edge of the street or sidewalk pavement, whichever is closer, shall be at least eighteen (18) feet (see Illustration for Table 17.15.03 [Additional Regulation 7], below. See Section 17.108.130 for allowed projections into setbacks.

Illustration for Table 17.15.03 [Additional Regulation 7]
*for illustration purposes only

8. On lots with only Residential Facilities, paved surfaces within required street-fronting yards, and any unimproved rights-of-way of adjacent streets, shall be limited to fifty percent (50%) on interior lots and thirty percent (30%) on corner lots. Exceptions: The maximum percentages of paved surfaces specified in this additional regulation may be exceeded within unimproved rights-of-way in the following cases upon issuance of a private construction of public improvements (P-job) permit or if undertaken directly by the City or by a private contractor under contract to the City:

a. Roadway construction or widening;

b. Sidewalk construction or widening; and

c. Any work pursuant to an approved final map, parcel map or final development plan pursuant to a Planned Unit Development (PUD) permit.

For purposes of this additional regulation, an unimproved right-of-way is the portion of a street or alley right-of-way that is not paved.

9. See Table 17.15.04 for reduced setbacks for smaller lots. See Section 17.108.130 for allowed projections into setbacks.

10. See Section 17.108.080 for the required interior side and rear setback on a lot containing two (2) or more living units and opposite a legally-required living room window.

11. In the RD Zone, on every corner lot which abuts to the rear a key lot which is in a Residential Zone, there shall be provided on the street side of such corner lot a side setback with a minimum width equal to one-half (½) of the minimum front setback depth required on the key lot and no less than the minimum side setback width required along an interior side lot line of the corner lot. However, such side setback shall only apply to the rear ten (10) feet of the corner lot, and not be required to exceed four (4) feet in width if it would reduce to less than twenty-five (25) feet the buildable width of any corner lot. Such setback shall be provided unobstructed except for the accessory structures or the other facilities allowed therein by Section 17.108.130 (see Illustration for Table 17.15.03 [Additional Regulation 12], below). See also Subsection 17.110.040.C for special controls on location of detached accessory buildings on such corner lots.

Illustration for Table 17.15.03 [Additional Regulation 12]
*for illustration purposes only

12. 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 depth 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.

13. In the RD Zone, for lots which abut an adjoining rear setback, the minimum rear setback depth shall be increased by an additional one-half (½) foot of rear setback depth for each additional one (1) foot of lot depth over one hundred (100) feet, up to a maximum rear setback depth of twenty (20) feet.

14. See Section 17.108.030 for allowed projections above height limits and Section 17.108.020 for increased height limits in certain situations.

17. Usable open space is only required on lots with two (2) or more primary living 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.

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

19. Maximum Lot Coverage and maximum Floor Area Ratio (FAR) only apply to lots with one to two dwelling units, excluding any permitted Accessory Dwelling Units. See Table 17.15.05 for applicable regulations.

a. New principal buildings that include ground floor Commercial Facilities; and

b. New Commercial Facilities located to the front of a Potential Designated Historic Property (PDHP) or Designated Historic Property (DHP), but only if the height of the new Commercial Facility in the area between the front property line and the front building elevation of the existing historic structure does not exceed fifteen (15) feet.

No front or side setback is required for existing Commercial Facilities. Also, no front yard setback is required for new Commercial Facilities if there is an existing context within the adjoining block face of no front yard setback. For the purposes of this limitation, an "existing context" of no front yard setback means that at least fifty percent (50%) of the existing buildings from street corner to street corner on the same side of the street have no front yard setback.

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

B.

Additional Regulations for Table 17.15.05:

1. Maximum Floor Area Ratio (FAR) only applies to lots that have a footprint slope of greater than twenty percent (20%). Lots less than four thousand (4,000) square feet may have a minimum of two thousand (2,000) square feet of floor area, regardless of FAR listed.

2. Lots less than four thousand (4,000) square feet may have a lot coverage of up to two thousand (2,000) square feet regardless of lot coverage percentage (%) listed.

D.

Height. Table 17.15.06 below prescribes height standards associated with different sloped lots. The numbers in the right-hand column refer to the additional regulations listed at the end of the Table. "N/A" designates the regulation is not applicable to the specified footprint slope category.
