DISCUSSION
Construction codes are constantly changing with the development of new products materials and methods,
and research performed in the building construction industry Updates to existing codes are reviewed and
voted on nationally on an annual basis Every three years new sets of codes are published with the
cumulative annual changes incorporated The 2003 set of International Codes and 2002 National Electrical
Code are the newly published set under review by the Development and Fire Departments

Usage of Non-Metallic (NM) cable in high-rise apartment buildings has been proposed by the Building
Official Current amendments to the Electrical Code have expanded the allowable usage of NM cable to
include up to five story apartments. Staff has proposed an amendment, already approved by the
Construction and Fire Prevention Board to allow up to five story apartments with wood studs and up to four
story apartments with metal studs
However staff has also proposed an amendment, not approved by the Board by a 5-2 vote to allow NM
cable in metal stud apartments above the four story level (which gets up into high-rise apartments) if
installed after the apartment breaker box. Hence the phrase (NM) cable in high-rise apartment buildings
Data has already been presented by staff showing that:
1 There is no documented extra fire hazard with the usage of NM cable over any other wiring method
2 There will not be an increase in insurance. rates and
3 There will not be any increase hazard to fire fighters, .and
4 While others try to refer to this as Residential Wiring" there is no such reference in the National
Electrical Code NM cable is an approved wiring method in commercial and residential uses including
apartments.
During April 6 2004 Pre-Council Worksession staff was directed to study the safety issues related to the
NM wiring within the staffs recommended amendments to the 2002 NEC For this reason consideration of
the adoption of the electrical code and related local amendments is being deferred to a date on or before
May 4 2004
Approval of the attached ordinances will establish an effective date of April 18 2004
