Every driveway bridge and portion thereof for vehicular access to private garages or private parking shall be designed and constructed as a minimum in accordance with the general requirements of this Code as amended by this Section.

This Section provides design loading for driveway bridges, driveway approach decks, garage floors, and carport floors. Secondly, this division provides for minimum prescriptive requirements for alterations or repairs of varying scope to existing driveway bridges. This Section considers the possibility of temporary heavy loads on unroofed vehicle approach decks due to construction equipment, moving vans, and heavy emergency or other vehicles using the deck. On these bases, the appropriate design loads have been determined.

In all cases lateral loads for wind or seismic shall be considered and provided for. Repairs and alterations of existing decks shall conform to the criteria pursuant to this chapter.

Section 1602B - Design Loads

Section 1602B.1 Case I.

Design loads for driveway bridges serving private residential parking garages/carports with restricted headroom and no repair or refueling. Design loads shall be pursuant to Chapter 16 of the California Building Code for concentrated load and uniform live load (Private or pleasure-type motor vehicle storage). Reduction of live load may be determined pursuant to Chapter 16 of the California Building Code. Design load summary as follows:

Wheel load:

Two (2) 2,000 lb. loads spaced five (5) feet apart.

Each concentrated load is to be placed upon any space a maximum of two and a half (2 ½) feet square pursuant to Chapter 16 of the California Building Code.

Uniform load:

One hundred (100) PSF with no allowable stress increase for duration of load. Live load reduction may be pursuant to Chapter 16 of the California Building Code.

Section 1602B.2 Case II.

Design loads for private vehicle access bridges serving a single family dwelling on a single lot fronting unimproved streets where the length of the building access path crossing the driveway bridge is fifty (50) feet or less. The following loads apply to the portion of such vehicle access bridges in the public right-of-way as well as the portion on private property. Pursuant to Chapter 16 of the California Building Code, this Section considers the gross weight of the maximum vehicle served to be twenty thousand (20,000) pounds for this condition (AASHTO H10 loading). The length of the access path is measured from the edge of pavement of the unimproved street to the building/garage/carport entry point. This concentrated load may be distributed in accordance with the provisions Chapter 16 of the California Building Code or, alternatively, the concentrated loads may be distributed in accordance with the Standard Specifications For Highway Bridges, 14th ed., 1989, or latest edition, as adopted by the American Association of State Highway and Transportation Officials, 444 North Capital street, N.W., Suite 225, Washington, D.C. 20001. Allowable stress increases for a load duration of seven (7) days may be used for this concentrated load.

A minimum uniform live load of one hundred (100) PSF, (Garages—General storage and/or repair of the California Building Code), shall be used. Reduction of live loads may be determined pursuant to Chapter 16 of the California Building Code. The condition of concentrated or uniform live load producing the greater stresses shall govern. The summary of these loads are as follows:

Wheel load:

Two (2) 8,000 lb. loads spaced five (5) feet apart.

Each concentrated load is to be placed upon any space a maximum of two and a half (2 ½) feet square.

May alternatively use AASHTO load distribution.

Uniform load:

One hundred (100) PSF with no allowable stress increase for duration of load. Live load reduction pursuant to Chapter 16 of the California Building Code.

Section 1602B.3 Case III.

Same As Case II, except building entry access path crossing the driveway bridge is more than fifty (50) feet. Same as for Case II, except the gross vehicle weight considered shall be thirty thousand (30,000) pounds (AASHTO H15).

Wheel load:

Two (2) 12,000 lb. loads spaced five (5) feet apart.

Each concentrated load is to be placed upon any space a maximum of two and a half (2 ½) feet square.

May alternatively use AASHTO load distribution.

Uniform load:

One hundred (100) PSF with no allowable stress increase for duration of load. Live load reduction pursuant to Chapter 16 of the California Building Code.

Section 1602B.4 Case IV.

Design Load for Private Residential Access Bridge Serving More than One Dwelling Unit or More than a Single Lot Fronting an Unimproved Street.

Design loads shall be the same as for Case III in this chapter.

Section 1603B—Alterations or Repairs to Existing Driveway Bridges.

Section 1603B.1 Case V.

Existing driveway bridges may need repairs as their structural system or moisture barrier system is often inadequate. Plans with the permit submittal, including concrete deck removal to install new deck waterproofing, for driveway bridge repairs should show the existing structural system for the driveway bridge so its adequacy to the design criteria of this Section may be checked.

A structural evaluation by an architect or engineer of the structure based on the design load criteria of this chapter, as appropriate, shall be provided for any driveway bridge repair for a bridge that does not have documented structural calculations.

Requirements for Joint Living and Work Quarters

Group F — Division 7 and 8

Group R — Division 7, 7.1, and 8

SECTION 3B.1 — General.

Section 3B.1.1 Purpose.

The purpose of this division is to provide alternative building standards and minimum standards of safety for commercially/industrially-oriented and residentially-oriented Joint Living and Work Quarters (JLWQ) purposes pursuant to California State Health and Safety Code (SCHSC) Section 17958.11. For clarification purposes, portions of Health and Safety Code Section 17958.11 is repeated as follows:

"(a) Any city or county may adopt alternative building regulations for the conversion of commercial or industrial buildings, or portions thereof, to joint living and work quarters. As used in this section, "joint living and work quarters" means residential occupancy by a family maintaining a common household, or by not more than four unrelated persons, of one or more rooms or floors in a building originally designed for industrial or commercial occupancy which include: (1) cooking space and sanitary facilities in conformance with local building standards adopted pursuant to CSHSC Section 17958 or 17958.5 and (2) adequate working space reserved for, and regularly used by, one or more persons residing therein...

It is the intent of the (California) Legislature that local governments have discretion to define geographic areas which may be utilized for joint living and work quarters and to establish standards for such occupancy, consistent with the needs and conditions peculiar to the local environment. The Legislature recognizes that building code regulations applicable to residential housing may have to be relaxed to provide joint living and work quarters in buildings previously used for commercial or industrial purposes."

Section 3B.1.2 Scope.

The provisions of this division shall apply to and may be used only for buildings or portions thereof originally designed for commercial or industrial purposes that have received City Planning approval for use as Joint Living and Work Quarters (JLWQ). City Planning approval shall be pursuant to Section 17.102.190 of the Oakland Planning Code or other City Planning approval indicating that the proposed use is consistent with California State Health and Safety Code Section 17958.11.

Section 3B.1.3 Applicability of City Planning and other Criteria for Joint Living and Work Quarters.

As provided in California Health and Safety Code Section 17958.11 and the Oakland Planning Code, the residential occupancy of joint living and work quarters is an accessory use to its primary use as a place of work. Accordingly, the provisions of this division shall apply only to buildings or portions of buildings that meet the following criteria:

1. The minimum floor area of an individual JLWQ shall be 660 square feet.

2. A minimum of 67% of the floor area of an individual JLWQ shall be designated as work area and the remainder shall be designated as residential area pursuant to paragraph 3 below. Up to 25% of the designated work area may be used for dual purposes such as telephoning, drawing, accounting, reading, planning, development of work projects, and sanitary facilities.

3. The areas of an individual JLWQ used for living, sleeping, eating, and cooking (habitable space) shall be designated as residential area. The residential area shall be secondary to the work area and shall not exceed 33% of the floor area of the individual JLWQ.

4. In an individual JLWQ, a designated residential area of up to 300 square feet may provide residence for no more than two persons. An additional resident can be accommodated for each additional 150 square feet of designated residential area. No individual JLWQ shall accommodate more than 10 persons regardless of the size of the designated residential area.

EXCEPTION: Residentially-Oriented Live-Work in the Urban Core may be in compliance with Planning Approval pursuant to interim measures adopted by the City Council or other City Planning approval as applicable.

Section 3B.1.4 Applicability of other Provisions.

Except as specified within this division, JLWQ that are commercially/industrially-oriented shall meet all applicable provisions of this code as for an F-1 Occupancy and JLWQ that are residentially-oriented shall meet all applicable provisions of this code as for an R-2 Occupancy apartment residential dwelling unit.

These additional measures shall be presented to the owner for consideration as part of the rehabilitation or restoration.

Section 3B.5.3 Lateral Load Regulations for R-7.1 Occupancy.

Section 3B.5.3.1 Lateral Loads.

The forces used to evaluate the structure for resistance to wind and seismic loads need not exceed 0.75 times the seismic forces prescribed by the current edition of the California Building Code (CBC). The seismic forces may be computed based on the R values tabulated in the CBC for similar lateral force-resisting systems. All deviations of the detailing provisions of the lateral-force-resisting systems shall be evaluated for stability and the ability to maintain load-carrying capacity at increased lateral loads. Unreinforced masonry bearing wall buildings shall comply with California Existing Building Code, Title 24, Part 10, Appendix Chapter 1, and as modified by this code. Reasonably equivalent standards may be used on a case-by-case basis when approved by the authority having jurisdiction.

Section 3B.5.3.2 Existing Building Performance.

The seismic resistance may be based upon the ultimate capacity of the structure to perform, giving due consideration to ductility and reserve strength of the lateral-force-resisting system and materials while maintaining a reasonable factor of safety. Professional engineering judgment may be exercised regarding the strength and performance of materials not recognized by regular code requirements. (California Historical Building Code, Title 24, Part 8)

Section 3B.5.3.3.

All structural materials or members that do not comply with detailing and proportioning requirements of the regular code shall be evaluated for potential seismic performance and the consequence of noncompliance. All members which might fail and lead to possible collapse, or threaten life safety, shall be judged unacceptable and appropriate structural strengthening shall be developed. The building should be evaluated as a system to ensure against progressive collapse.

Section 3B.5.3.4 Load Path.

A complete and continuous load path, including connections, from every part or portion of the structure to the ground shall be provided for the required forces. It shall be verified that the structure is adequately tied together to perform as a coherent system when subjected to earthquake forces.

Section 3B.5.3.5 Parapets.

Parapets and exterior decoration shall be investigated for conformance to the regular code requirements for anchorage and ability to resist prescribed seismic forces. An exception to regular code requirements shall be permitted for those parapets and decorations which are judged not to be a hazard to life safety.

Section 3B.5.3.6 Historical Records.

Historical records of the structure or similar structures may be used in the evaluation, including the effects of subsequent alterations.

Section 3B.5.3.7 Nonstructural Features.

Nonstructural features of a structure converted to R-7.1 use, such as exterior veneer, cornices and decorations, which might fail and create a life-safety hazard in an earthquake, shall be investigated. Their ability to resist seismic forces shall be verified, or the feature shall be strengthened.

Section 3B.5.3.8.

Partitions and ceilings of corridors and stairways serving an occupant load of 30 or more or located above the first story shall be investigated to determine their ability to remain in place when the building is subjected to earthquake forces.

SECTION 3B.6 — Minimum Facilities and Shell Construction.
