Additional Regulations for Table 17.13.03:

1. See Sections 17.106.010 and 17.106.020 for exceptions to lot area, width mean and street frontage regulations. In the RH-3 Zone, the minimum average lot width of all lots within a subdivision shall be ninety (90) feet, and the minimum lot width of any individual lot within such subdivision shall be seventy-five (75) feet.

2. In the RH-4 Zone, for Subdivision Maps of four (4) or fewer lots where each lot created has a buildable area slope of less than or equal to twenty percent (20%), the minimum lot size is six thousand five hundred (6,500) square feet. For Subdivision Maps where any one lot buildable area slope is greater than twenty percent (20%) or for Subdivision Maps of five (5) or more lots, the minimum lot size is increased to eight thousand (8,000) square feet.

a. In order to determine buildable area slope of a subdivision, each lot shown on the Subdivision Map shall indicate the buildable area in dashed lines. The buildable area slope is measured at the steepest point between the front and rear setbacks (not included within the side setbacks).

3. See Subsection 16.16.170.F in the Subdivision regulations for additional regulations regarding minimum lot size. In the RH-3 Zone, the minimum average lot area of all lots within a subdivision shall be twelve thousand (12,000) square feet, and the minimum lot area of any individual lot within such subdivision shall be ten thousand (10,000) square feet.

4. See Section 17.103.080 and Chapter 17.88 for development standards applicable to permitted Accessory Dwelling Units. Also applicable are the provisions of Section 17.102.270 with respect to additional kitchens for a dwelling unit, and the provisions of Section 17.102.300 with respect to dwelling units with five (5) or more bedrooms.

5. 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.

6. In the RH-4 Zone, if adjacent lots abutting the side lot lines of the subject lot both contain principle Residential Facilities that have front setbacks with a depth of less than twenty (20) feet, 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 principle Residential Facility on the adjacent lots having the deeper front setback depth, provided such projection is enclosed, has a wall height of at least eight (8) feet, and has a width of at least five (5) feet. In the case of a corner lot or lot that has one or more vacant parcels next to it, this same principle shall apply if the nearest non-vacant lots to each side of the corner lot, or to each side of a lot that has one or more vacant parcels next to it, have less than a twenty (20) foot front setback (see Illustration for Table 17.13.03, [Additional Regulation 6], below). Also, see Section 17.108.130 for allowed projections into setbacks.

Illustration for Table 17.13.03 [Additional Regulation 6] *for illustration purposes only

7. The minimum front setback depth required by the applicable individual zone 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 the edge of the pavement to a garage or carport elevation containing one or more vehicular entries shall be at least eighteen (18) feet (see Illustration for Table 17.13.03, [Additional Regulation 7], below). See Section 17.108.130 for allowed projections into setbacks.

Illustration for Table 17.13.03 [Additional Regulation 7] *for illustration purposes only

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

9. The minimum interior side setback for all lots with a footprint slope that exceeds twenty percent (20%) is the greater of the two (2) listed setbacks - in the RH-1 and RH-2 Zones: either six (6) feet or fifteen percent (15%) of the lot width mean, whichever is greater; in the RH-3 Zone: either six (6) feet or ten percent (10%) of the lot width mean, whichever is greater; and in the RH-4 Zone: either five (5) feet or ten percent (10%) of the lot width mean, whichever is greater. Also, see Section 17.108.130 for allowed projections into setbacks.

10. In all RH Zones, 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 twenty (20) feet of the corner lot, and not be required to exceed five (5) 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 17.13.03. [Additional Regulation 10], below). See also Subsection 17.110.040.C for special controls on location of detached accessory buildings on such corner lots and Section 17.108.130 for allowed projections into setbacks.

Illustration for Table 17.13.03 [Additional Regulation 10] *for illustration purposes only

11. 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 reduced to less than ten (10) feet. Also, see Section 17.108.130 for allowed projections into setbacks.

12. 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 forty (40) feet.

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

14. In all RH Zones, if at least sixty percent (60%) of the buildings in the immediate context are no more than one (1) story in height, the maximum wall height shall be fifteen (15) feet within the front twelve (12)

feet of buildable area. The immediate context shall consist of the five (5) closest lots on each side of the project site plus the ten (10) closest lots on the opposite side of the street; however, the Director of City Planning may make an alternative determination of immediate context based on specific site conditions. Such determination shall be in writing and included as part of any approval of any variance, conditional use permit, design review, determination of exemption from design review, or other special zoning approval or, if no special zoning approval is required, part of any Planning Department approval of a building permit application.

15. See applicable design review criteria for more specific bulk standards.

16. Off-street parking and loading shall be provided as prescribed in the off-street parking and loading requirements in Chapter 17.116. Bicycle parking shall be provided as prescribed in the bicycle parking regulations in Chapter 17.117. Additional parking standards apply within the S-11 Zone, as prescribed in Chapter 17.92.

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

18. A second primary unit may only be granted in the RH-4 Zone upon determination that:

i)

The project is not located within the S-9 Fire Safety Protection Combining Zone; and

ii)

The minimum pavement width along the entire length of the adjoining street is at least twenty-six (26) feet, and all streets connecting the lot to the nearest arterial street (as designated by the City of Oakland General Plan Land Use and Transportation Element) have a minimum pavement width of at least twenty-six (26) feet.
