Wood-Frame Soft-Story Structures
The city of Burbank has established a voluntary program for the retrofit of existing wood frame residential buildings with soft, weak, or open front walls. The Burbank Municipal Code Title 9, Chapter 1, Article 7, Division 4 requires that Chapter A4 of the 2012 International Existing Building Code (IEBC) be followed as part of this voluntary effort.
Burbank’s voluntary wood-frame soft-story program applies to existing buildings that have the following characteristics:
- Wood-frame construction
- Two or more stories
- Occupants are transient in nature (IEBC, R-1) or contain more than two dwelling units for more permanent occupants (IEBC, R-2)
- Ground floor contains parking or similar open space containing soft, weak or open-front wall lines; or the walls of any story or basement are laterally braced with nonconforming structural material and a soft or weak wall line exists
The city of Burbank established this ordinance with compliance on a voluntary basis. Therefore, there are no deadlines for conformance. However, it is recommended that the provisions outlined in the municipal code be followed on a timely basis to promote public welfare and safety by reducing earthquake-related damage of buildings of wood-frame soft-story construction.
