Ordinances No. 163836 and No. 165319 (High-Rise Retrofit Ordinances), effective August 21, 1988 and November, 1989 require all existing high-rise buildings*, for which a building permit was issued prior to July 1, 1974, except Group R Division 1 occupancies, to comply with the requirements of LAMC Section 91.8604. These ordinances establish building, electrical, and fire protection code requirements. In order to insure consistent application of these ordinances, to clarify the requirements and to provide interpretations for the most commonly asked questions, the following information is provided:

•  Building Requirements and Information
• Electrical Requirements and Information
• Fire Protection Requirements and Information

The Department of Building and Safety has been granting extensions of time to obtain all necessary permits to petitioners who demonstrate a considerable effort and progress in complying with LAMC Section 91.8604. Definition: * A high—rise building is a building of any type of construction having floors (as measured from the top of the floor surface) used for human occupancy located more than 75 feet above the lowest floor level having building access. BUILDING REQUIREMENTS AND INFORMATION 1. All buildings affected by these Ordinances are required to be in compliance with LAMC Section 91.8604 and Title 24, Part 2 Section 2-1733 thru 2-1747. 2. Three sets of building plans, indicating compliance with the ordinance, must be submitted to the Building Plan Check Section. These plans shall be approved prior to obtaining a building permit and starting of construction. The building plan shall state that separate plans for electrical and fire sprinkler designs will be submitted to the Fire Safety Division in compliance with the requirements of LAMC Section 91.8604(f).  The building permit and plan check fees shall be based on the total value of all construction or work for which the permit is issued, including lobby enclosures, replacing fire proofing, patching penetrations in fire rated walls, electrical work, emergency standby electrical power, fire protective signaling systems, emergency exit lighting, fire pumps, automatic fire sprinkler systems, standpipe systems installation and any other permanent equipment installations. (LAMC Sections 91.0102, 91.0103, 9l.0304(b)&(c)) 3. Elevator Lobbies All elevators on all levels shall open into elevator lobbies which are separated from the remainder of the building, including corridors and other exits, by walls having a fire-resistive rating of not less than one-hour. All lobby openings other than those for elevator doors, stairway enclosures, and ducts shall be protected with threefourths-hour automatic-closing fire assemblies with magnetic hold-open devices for door closure actuated by combustion products-type smoke detectors located in the elevator lobbies. All ducts serving the lobbies shall have one-hour fire dampers at penetrations of one-hour fire resistive separations. EXCEPTION: The main entrance level elevator lobby. 4. Each required stairshaft that extends to the roof or the highest floor of the building shall be provided with a minimum ventilation opening of 20 square feet at the roof level. The 20 square foot opening shall be accessible from the roof and from the inside of the stairshaft. In addition, the opening must be capable of being resealed to permit the Fire Department to pressurize the stairshaft after ventilation is completed.

a. The stairshaft ventilation opening shall be identified by a sign posted on the upper landing in the stairshaft. b. The following methods, subject to Fire Department approval, are acceptable for providing stairshaft ventilation:

1. Roof access door 3’0” X 6’8” 2. 20 square foot roof hatch 3. 20 square foot skylight

5. The building plans are to reflect the location of the water storage tank, emergency generator room, fire pump room, elevator lobbies, access for the physically handicapped if required, and the effect on parking, if any. In order to provide floor space for a water storage tank and/or fire pump(s), existing parking areas may require restriping (use of compact stalls) in accordance with Section 12.21 of the Zoning Code. A reduction of required parking spaces may be allowed as part of the plan review process of the Department of Building and Safety 6. Sections 2-110(b)11A5, 2-110(b)11B4 of Part 2 of Title 24 of the California Administrative Code specifies the requirements for access by the physically disabled when any alterations, structural repairs or additions are made to existing buildings-see MGD #80, Disabled Access Policy No. 24, for Access Requirements triggered by these ordinances. 7. LAMC Section 91.0303(e) limits the Department in issuing permits to alter historical buildings or structures. Buildings that are listed on the City of Los Angeles’ “List of Historic Monuments” must get approval from the Cultural Affairs Department prior to the issuance of any permit. Buildings included in the “National Register of Historic Places” or that have been designated as an Historic Building by the State of California must be reviewed by the Cultural Affairs Department prior to the issuance of any permit. Such review may require an environmental impact report. ELECTRICAL REQUIREMENTS AND INFORMATION 1. ELEVATOR SYSTEM

a. Smoke Detectors Each elevator lobby, except main entrance level lobby, shall be provided with an approved smoke detector located on the lobby ceiling. All lobby doors shall close on actuation of any fire alarm initiating devices on that floor, only.  The elevator controls shall be designed so that the activation of a lobby smoke detector will cause all elevators serving that lobby to return nonstop to the main entrance level and then be under manual control only. Smoke detectors for elevator lobbies shall be annunciated at the main alarm panel on a per-floor basis.

2. FIRE-PROTECTIVE SIGNALING SYSTEM

a. When a sprinkler system is installed in an existing high-rise building, the fire alarm system must monitor the sprinkler water flow and valve tampering on a floor-by-floor basis. These functions shall be annunciated at the main fire alarm annunciator panel. Existing fire alarm control and annunciator panels in many buildings do not have the capacity to handle additional zones and circuits; currently either underpowered or at maximum power capacity due to tenant improvements over the years. The annunciation of elevator lobby smoke detectors, sprinkler water flow, and floor control valve tamper on an existing fire alarm annunciator panel will be accepted, provided the panel has adequate space and capacity. If an auxiliary interface panel is intended to be installed, the panel must be fully compatible with the existing fire warning system and must be listed by the California State Fire Marshal and a City recognized electrical testing laboratory for combined use with the existing specific listed unit and model as an auxiliary fire alarm control and annunciator panel. Existing fire warning systems are acceptable provided all wiring and alarm initiating devices are supervised. The existing system shall have the capability of receiving subsequent alarm initiation after each silencing.  New fire warning control and annunciator panels may be installed provided they are fully compatible with the existing system and all of the aforementioned functions shall be demonstrated in a Fire Department Regulation No. 4 test. If the building signaling system needs to be replaced, it shall conform to the requirements of the Los Angeles City Fire Code, Division 118 and 122, and Section 1807 of Title 24, California Code of Regulations for new high rise buildings, and the Los Angeles City Electrical Code. Existing fire warning systems and initiating devices (i.e. smoke detectors and manual pull stations) shall not be taken out of service prior to inspection and final approval of the new system by the Department of Building and Safety and the Fire Department. (LAMC Section 57.907.1.3) The Fire Department shall be notified immediately whenever the fire warning system becomes inoperative. A Fire Watch shall be established using approved Fire Safety officers whenever the fire warning system is inoperative or out of service. Down time shall be limited to non-business hours and a Fire Watch log shall be maintained. (LAMC Section 57.915.2) Alarm devices shall give the same distinct and uniform audible sound on all floors (bells and speakers shall not be installed in the same system). (LAMC Section 57.907.5.2) When a new fire warning system and panels are being installed, initiating devices on all floors shall be tied into the new panel within a time period approved by the Fire Department. This will eliminate having a dual system within the building. b. Manual pull stations shall be located in the corridor on each building level adjacent to stair shafts, fire escapes and ground floor exits. Sounding devices shall be clearly audible on the floor of actuation with the capability of sounding a general alarm throughout the building by manual means from the building control station, or fire alarm panel location.

(1) Audibility Level Alarm indicating devices of a fire alarm system intended to alert all occupants shall be so located as to cause a level of audibility of not less than 10 db above ambient noise levels measured four feet above the floor. (2) Existing Systems Existing fire protective signaling systems complying with Los Angeles Fire Code will be allowed to remain. Installation, alteration or repair of Fire-protective signaling systems shall be performed under permit issued by the Fire Safety Division of the Department of Building & Safety. If Plan Check is required, plans are to be approved prior to the issuance of the permit. The actuation of any fire alarm initiating device shall cause all audible devices to sound throughout the floor of actuation.
