TheCaliforniaBuildingStandardsCodeappliesto all occupancies throughout the State of California as annotated.

A city, county, or city and countymay establish more restrictive building standards reasonably necessary because of local climatic,geological, or topographical conditions. Findings of the local condition(s) and the adopted local building standard(s) must be filedwith the California Building Standards Commission to become effective and may not be effective sooner than the effective date ofthis edition of theCaliforniaBuilding StandardsCode. Local building standards adopted to be applicable to previous editions of theCalifornia Building Standards Code do not apply to this edition without appropriate adoption and the required filing.

GROUP I. ADMINISTRATIVE REGULATIONS

Group I regulations apply to existing and new elevator installations.

Article 7-1. Application

Application.7-3000.(a)WhereApplicable.The Elevator SafetyOrders are applica-

ble to elevators in the state of California except:

1. Elevators under the jurisdiction of the United States govern-ment.

2. Elevators located in a single-unit private home and not ac-cessible to the public.

3. Elevators located in a multi-unit residential building servingno more than two dwelling units and not accessible to the public.

NOTE: Unless otherwise designated in this subchapter, the termdivision refers to the current Division of Occupational Safety andHealth or any of its predecessors including the former Division of In-dustrial Safety or the Division of Occupational Safety and Health Ad-ministration. Reference to the former Division of Industrial Safety orDivision of Occupational Safety and Health Administration in theseorders is meant to refer to their successor, the Division of OccupationalSafety and Health, or any subsequent successor agency.

(b) Use and Precedence of Orders.

1. When ASME A17.1-1996 is cited or incorporated by refer-ence in these Orders, it shall mean the 1996 edition of ASMEA17.1, unless otherwise indicated.

2. The Elevator Safety Orders shall apply if any difference ex-ists between the Elevator Safety Orders and ASME A17.1-1996;or any other code, document or standard referenced in ASMEA17.1-1996. Where a specific provision varies from a generalprovision, the specific provision shall apply.

3. If a section in the Elevator Safety Orders makes a cross-reference to a section, rule or table in ASME A17.1-1996, suchcross-referencing shall be that which is shown in ASMEA17.1-1996 unless the referenced section, rule or table has beenamended in the Elevator Safety Orders.

4. If a section, rule or table in ASME A17.1-1996 makes across-reference to another section, rule or table in ASMEA17.1-1996, such cross-referencing shall be that which is shownin ASME A17.l-1996, unless the referenced section, rule or tablehas been amended in the Elevator Safety Orders.

(c) Devices Included. The devices covered by the regulationsof the Elevator Safety Orders are included under the term eleva-tor as used in the Labor Code. These orders apply to the follow-ing:

That portion of a floor, balcony, or

platform used to receive and discharge passengers or freight. Al-though the vertical level is normally fixed, there are instanceswhere the landing is arranged to vary vertically to satisfy givenconditions.Landing, Bottom Terminal. The lowest landing served by the

elevator which is equipped with a hoistway door and hoistwaydoor locking device which permits egress from the hoistway side.Landing, TopTerminal.The highest landing served by the ele-

vator which is equipped with a hoistway door and hoistway doorlocking device which permits egress from the hoistway side.Landing, Unenclosed. A landing which is open to the atmo-
