17.65.010 Title, purpose, and applicability.

The provisions of this chapter shall be known as the Housing and Business Mix Commercial Zones Regulations. This chapter establishes land use regulations for the HBX-1, HBX-2 and HBX-3 zones. The purposes of the Housing and Business Mix zones are to:
Allow for mixed use districts that recognize both residential and business activities.
Establish development standards that allow residential and business activities to compatibly co-exist.
Provide a transition between industrial areas and residential neighborhoods.
Encourage development that respects environmental quality and historic patterns of development.
Foster a variety of small, entrepreneurial, and flexible home-based businesses.
Housing and Business Mix 1 (HBX-1) Zone. The HBX-l zone is intended to provide development standards that provide for the compatible coexistence of industrial and heavy commercial activities and medium density residential development. This zone recognizes the equal importance of housing and business.
Housing and Business Mix 2 (HBX-2) Zone. The HBX-2 zone is intended to provide development standards for areas that have a mix of industrial, certain commercial and medium to high density resi-dential development. This zone recognizes the equal importance of housing and business.
Housing and Business Mix 3 (HBX-3) Zone. The HBX-2 zone is intended to provide development standards for areas that have a mix of industrial, heavy commercial and higher density residential development. This zone is intended to promote housing with a strong presence of commercial and industrial activities. (Ord. 12872 § 4 (part), 2008; Ord. 12772 § 1 (part), 2006)

17.65.020 Required design review process.

A. Except for projects that are exempt from design review as set forth in Section 17.136.025, no Building Facility, Telecommunications Facility, Sign, or other associated structure shall be constructed, established, or altered in exterior appearance, unless plans for the proposal have been approved pursuant to the design review procedure in Chapter 17.136, and when applicable, the Telecommunications regulations in Chapter 17.128, or the Sign regulations in Chapter 17.104.
B. Conformance to the “HBX Design Guidelines Manual” is required for any change to the exterior of a building that requires a building permit in the HBX-1, HBX-2 and HBX-3 zones.
C. Where there is a conflict between the design review criteria contained in Section 17.136.070 and the design objectives contained in the “HBX Design Guidelines Manual”* the design objectives in the “HBX Design Guidelines Manual” shall prevail. (Ord. 12776 § 3, Exh. A (part), 2006: Ord. 12772 § 1 (part), 2006)

* Editor’s Note.-- The “HBX Design Guidelines Manual,” referred to in this chapter, is incorporated by reference as if fully set forth herein by Section 2 of Ordinance 12772. A copy of this manual is kept on file in the Oakland City Hall.

3. A conditional use permit for an FAR of 3.0 in the HBX-3 zone may only be granted upon determination that the proposal conforms to the general use permit criteria set forth in the conditional use permit procedure in Chapter 17.134 and to the following additional use permit criteria:
A. That the scale of buildings is reduced through the articulation and massing of street facing façades into a series
of smaller forms.
B. That the additional floor area ratio does not significantly decrease the solar access of existing adjacent single
family homes or duplexes to a degree greater than would be created if the facility were built according to the
base FAR.

Projects on through lots require this minimum fifty (50) percent on only the longest lot frontage to qualify as a mixed use project for this section.
B. For projects described in subsection A, the maximum number of units permitted on a lot shall not be affected by the nonresidential floor area provided on the same lot. Conversely, for these projects the maximum floor area allowed on a lot shall not be affected by the number of living units provided on the same lot. For projects described in subsection A, this subsection supercedes the requirements in Section 17.106.030.
C. Section 17.106.030 describes how to calculate density and floor area ratio for mixed use projects not included in subsection A. (Ord. 12772 § 1 (part), 2006)
