TO: Mayor and City council
FROM: City staff
SUBJECT: Recommendation to Adopt an Emergency Ordinance to Amend
the Potentially Hazardous Buildings Ordinance in Order to
Extend the Time Period for Submission of Engineering
Reports
:J;NTRODUCTION
This staff report recommends that the city Council adopt an
amendment to Ordinance #1748 (CCS) related to the repair and
retrofitting of potentially hazardous structures in order to extend
the deadline on the requirement for owners of damaged sOft-story
structures to submit engineering reports.
BACKGROUND
On June 21, 1994, the city Council adopted an emergency ordinance
relating to the repair and retrofitting of potentially hazardous
structures, lncluding soft-story structures.
The ordinance
requires that within 120 days of the effective date of the
ordinance, or by October 21, 1994, owners of soft-story buildings
damaged by the
earthquake
submit
an
engineering report
demonstrating whether the building complies with the Earthquake
Design Standards contained in the Uniform Building Code.

Due to the fact that it has taken longer than anticipated to
identify the soft-story buildings damaged by the January 17
Northridge Earthquake and prepare the notice, staff is recommending
that the deadline be changed to February 1, 1995. This extension
will give property owners a reasonable time period in which to
obtain the required engineering report.
~UDGET/FINANCIAL IMPACT
This recommendation will have no budgetary or financial impacts.
RECOMMENDATION
It is recommended that the city council adopt an amendment to
Section 4 of Ordinance #1748 as reflected in Attachment "A" to
extend the deadline for the submission of engineering reports on
damaged soft-story structures.
Attachment "A": Amended ordinance #1748

January 17, 1994 Northrldge earthquake and its aftershocks; and

especlally
susceptlble to damage ln the event of major earthquakes and pose a
substantial risk to publlC health, safety, and welfare; and
WHEREAS, for the reasons set forth above, and for the
protection of the public health, safety and welfare, on June 21,
