LACC Exhibit Structure and Building Permit Information
Effective January 1, 2009
Please refer to the following criteria for designing and building temporary exhibit structures
at the Los Angeles Convention Center (LACC).
All structures and related sub-assemblies must be designed, assembled, and configured so
that the entire exhibit project, and all related components, are “structurally sound” and
“seismically stable”. Furthermore, all said structures must be designed and built as per all
applicable Federal, State, and local building and fire codes, regulations, and policies. In the
Uniform Building Code (UBC), Los Angeles is listed in seismic zone #4.
Exhibitors are responsible for assuring that their exhibits are designed and built in
accordance with the general requirements mentioned above. With this in mind, exhibits
may, or may not, be inspected depending on a number of variables. When inspections are
performed, they are usually brief focusing only on “general” structural integrity and stability.
Structures Requiring Permits
Structures that meet the following criteria require an on site structural/seismic inspection by
the Department of Building and Safety, and the issuance of a building permit. The
inspection/permitting fee for Category I or II exhibits is $145.00 payable to the LACC. For
questions regarding payment, please contact the LACC Exhibitor Services Division at
(213) 741-1151 ext 5470.
Exhibit Structure Categories
When exhibit structures meet certain criteria, additional information must be sent to the
LACC Building Superintendent/Show Operations, to determine if the design meets minimum
building standards. For this purpose, exhibit structures are separated into two (2) categories
as shown below.
.. Standard structures that exceed 12 feet in height.
.. Stairs/steps over 30 inches tall, but not exceeding 48 inches tall.
.. 2-story structures
.. Platforms and stages exceeding 30 inches in height above the floor intended to carry
live load, or stair/steps exceeding 48 inches in height above the floor intended to carry
.. Expansive 1-story structures that contain: overhead beams; signage; truss; cantilevers;
etc., of considerable weight and/or span
.. Video Wall structures
For Category I structures, sending structural information is optional. Exhibitors that would
like to have their plans reviewed can fax or E-mail drawings and related specifications to the
LACC Building Superintendent/Show Operations at the number/address provided at the end
of this document. If sending e-mail, please send renderings and/or drawings in a .pdf or
.jpeg Image format. Do NOT send drawings electronically in .dwg format.
For Category II structures, exhibitors must send two (2) sets of engineered drawings and
related specifications to LACC Building Superintendent/Show Operations at the address
shown below. The Superintendent will forward one (1) set to the Fire Inspector for review.
Drawings must be in a scale that is “clear and legible” and state all relative dimensions
addressed below in inches and feet (do not send metric.) 11-inch by 17-inch drawings are
preferable “IF” information is clearly ascertainable. Further, drawings must be “recently”
reviewed, approved, and stamped by a licensed Structural or Civil Engineer registered in the
United States. Drawings must have the engineer’s original “wet stamp”, signature, and
current date of license expiration. Old drawings and/or copies not containing an original
“wet stamp” are not acceptable and will not be approved. Drawings must be current and
must refer to the specific event (Show) name for which they are being submitted.
Furthermore, drawings must be accurate as to the design and configuration of the
respective display(s). Please include perspective/isometric drawings as well to better define
the project. Sending “preliminary” renderings or drawing via e-mail is acceptable provided
they are sent in a .pdf or .jpeg Image format, however; final engineer approved “wet-
stamped” drawings must be mailed or delivered.
In addition to standard engineering details, Category II drawings must contain the following
1. Live load rating of the stage, platform, or 2nd story deck. The code requires a
minimum rating of 125 lbs. per sq. ft.
2. Stair detail showing the rise and tread depth of each stairway. The code requires the
maximum rise (measurement from the top of one step to the top of the next step) to
be 7 inches. The code requires the minimum tread depth (measurement of tread
from front to back, or heel to toe), to be 11 inches along any portion of the step(s).
Spiral stairways are not allowed at the LACC.
3. Width of stairways. Minimum width (clearance) for stairways is 36 inches.
Handrails that protrude into the stairway must be considered when determining
clearance. The clearance must be measured from the edge of the handrail to the
opposing handrail/guard rail.
4. Guard railing detail showing height of railing and the internal make up (construction)
of the railing. The code requires the guard railing to be a minimum 42 inches high
on platforms, decks, stairways, and stair landings. The internal construction and
make up of the guard railing must be such that a 4 inches sphere cannot pass
through any portion of the guard railing, and engineered to withstand the force of
person(s) falling into said railing, thereby protecting them from falling through.
5. Detail showing the placement and height of the handrails. The code requires all
stairs taller than 30 inches to have a handrail installed at a height of 34 to 38 inches
above the step(s).
Towers and Narrow Walls: For proper seismic stability, the height to base ratio in each
direction (width and depth) should be a maximum of 3 to 1 respectively. If a wall or tower is
15 feet high, the base dimensions should be at least 5 feet wide and 5 feet deep. Towers or
walls designed to have a greater ratio than 3 to 1 can be seismically secured by installing
seismic support cables from the top of the structure to rigging points in the ceiling (where
available), or by possibly adding weight to the base.
Covered Structures: Exhibits containing structures that are covered with fabric or solid
materials exceeding an accumulated total of 750 sq. ft. may require the installation of an
automatic fire sprinkler system. The allowable amount of covered area in LACC meeting
rooms may be substantially less than 750 sq. ft. Please refer to the “LACC Information
Regarding Covered Areas” guide for more information.
Door Handles: All door handles must be a lever type handle to accommodate those with
disabilities. The old cylindrical type of handle (door knob) is no longer approved.
Maximum Occupancy – Exhibit Floor Level: Rooms and/or spaces created within an
exhibit that have only one exit path from the room or space are limited to a maximum
occupancy of 49 persons. All spaces designed for occupancy greater than 49 persons must
have at least two (2) exits located at opposite ends of the room/space.
Maximum Occupancy – Elevated Decks: Two (2) story structures that have only one (1)
stairway accessing the 2nd level are limited to a maximum occupancy of nine (9) persons.
To achieve a greater occupancy than nine (9) persons, two (2) “separate” stairways that
access the 2nd level from two (2) opposing sides must be provided. The concept here is to
create another form of exiting from the 2nd level in the event one (1) exit becomes blocked.
Corridors: The maximum length for any corridor or series of corridors allowing only one
way in and out (dead-end) is 20 feet. To further clarify, the distance a person must travel
from the end of a corridor or narrow pathway (dead-end) to an open space containing an
exit cannot exceed 20 feet. Corridors longer that 20 feet must be open on both ends to
allow exiting. Conference rooms or exhibit spaces that extend beyond a 20 foot corridor
may require a 2nd exit within the room/space. Exhibitors planning the use of corridors are
urged to send renderings and drawings of their proposed plan while in the concept design
phase to assure that said design will be approved.
Exit Plan: Exhibits that are 400 sq. ft. or larger must submit an “exit plan” for the Fire
Inspector’s review and approval. Drawings shall be represented in “plan view” and shall
contain arrows that denote all of the paths in & out of the booth space or LACC meeting
room space. The exit plan shall also show the respective dimensions (clearances) of doors,
corridors, and other pathway structures that limit the exit path. Dimensions must be in feet
Recessed Exit Doors: Exit doors must swing open in the direction of traffic exiting the
exhibit. Exit doors shall remain unlocked during all show hours, and during all times in
which people are in the respective booth. Exit doors cannot swing open (protrude) into any
egress aisle designated by the Fire Department. Exit doors that must lead to the egress
aisles must be recessed so that exiting into the aisle is accomplished while preventing the
door from physically swinging into the fire aisle.
Stair and Turntable Delineation: The front edge of the first and last step in a series of
stairs must be delineated with a contrasting color to indicate the beginning and end of each
respective stairway. Where landings are used, the stairway on each side of the landing
(above & below) must be delineated. Regarding turntables or other approved moving floor
structures, the entire surface of any moving turntable must be in contrast to the finish of the
surrounding (stationary) floor to clearly delineate the moving element. Delineation may be
done by means of color, texture, material, etc., as long as an acceptable contrast and
delineation is accomplished.
Fire Alarm & Suppression Devices: Exhibitors with booth spaces containing any LACC
fire related alarm or suppression device(s) such as: pull alarms; fire bells; fire hose cabinets
or reels; fire extinguishers; sprinkler heads; fire sprinkler shut-off valves; etc., must design
their exhibit in such a manner that does not impede or limit the operation, and/or access to
said devices. Further, all signage associated with said devices and/or any of the building’s
permanent “EXIT” signs must be visible to the public from various vantage points as
intended. Exhibitors can seek approval, via written request, to cover exiting signs with
temporary supplemental signage that accomplish the intended purpose of the original
sign(s). Request must include renderings/drawings and related details of the proposed
project. Exhibitors are responsible for creating and installing all approved temporary
Plan Review, Approvals, and Field Inspection: Exhibit plan/design approvals are
tentative and are merely an acknowledgement that information sent in by the exhibitor was
reviewed, and no issues were found at the time of review. Approvals are based on the
information supplied by the exhibitor and are subject to on-site inspection. The LACC and
the LAFD are not responsible for items missed in the review process. Exhibitors are
responsible for designing and building exhibit structures that comply with all exhibit related
policies, regulations, and codes, including all of the requirements listed within this document.
If during site inspection it is determined that the exhibit violates a building or fire code,
thereby requiring correction, the exhibitor shall be solely responsible for making the
Show Management Rules & Regulations: Exhibitors must always check with Show
Management for specific show rules, regulations, and levels of review and approvals for
each respective event. Conditions that may be allowed at one show, may not be allowed in
