[SML] Bonding seats in California

[Bill Conner]

So the 2015 IBC - which I believe CA adopts with amendments - says:

1029.14 Seat stability. In a building, room or space used for
assembly purposes, the seats shall be securely fastened to the
floor.
Exceptions:
1. In a building, room or space used for assembly purposes
or portions thereof without ramped or tiered
floors for seating and with 200 or fewer seats, the
seats shall not be required to be fastened to the floor.
2. In a building, room or space used for assembly purposes
or portions thereof without ramped or tiered
floors for seating, the seats shall not be required to
be fastened to the floor.
3. In a building, room or space used for assembly purposes
or portions thereof without ramped or tiered
floors for seating and with greater than 200 seats, the
seats shall be fastened together in groups of not less
than three or the seats shall be securely fastened to
the floor.
4. In a building, room or space used for assembly purposes
where flexibility of the seating arrangement is
an integral part of the design and function of the
space and seating is on tiered levels, not more than
200 seats shall not be required to be fastened to the
floor. Plans showing seating, tiers and aisles shall be
submitted for approval.
5. Groups of seats within a building, room or space
used for assembly purposes separated from other
seating by railings, guards, partial height walls or
similar barriers with level floors and having not
more than 14 seats per group shall not be required to
be fastened to the floor.
6. Seats intended for musicians or other performers
and separated by railings, guards, partial height
walls or similar barriers shall not be required to be
fastened to the floor.

Exception 4 may cover you for the IBC.  Do keep in mind codes and
standards are minimums for safety, not a guide for good design.  If
someone is injured when they fall off the portable risers, it is
likely to cost the building owner more than the cost of 200 chairs.
