2 #SJGEQI0A0D3KMAv2
WHEREAS, California Health and Safety Code Section 17958.7 requires the City Council to make express findings of the necessity for modifications to the building standards contained in the 2025 California Building Standards Code; and
WHEREAS, in support of these modifications and changes, the City Council of the City of Pasadena hereby expressly finds that the amendments and modifications to building standards contained in the 2025 California Building Standards Code as adopted by the City are reasonably necessary due to the following local climatic, geological or topographical conditions.
Now, Therefore, the City Council of the City of Pasadena finds local justifications as follows:
Justification: Climatic. The presence of the San Gabriel Mountains along the foothills of the City allows winds patterns during certain climatic conditions and certain periods of the year. Further, intermittent Santa Ana wind conditions occur from September to March allowing conditions that create the potential for high velocity winds with high temperature.
In addition, the region is within a climate system capable of producing major winds, fire and rain related disasters, including but limited to, those caused by the Santa Ana winds and El Nino (or La Nina) subtropical-like weather.
Justification: Climatic. The City of Pasadena is located within the San Gabriel Valley region of Southern California which has extreme arid conditions and periods of severe drought. These conditions can cause extremely dry brush and fauna in the Wildland Urban Interface of the San Gabriel Mountains which has been identified as Fire Hazard Severity Zones by the Office of the State Fire Marshal.
Justification: Geological. The Safety Element of the General Plan identifies earthquake fault risk in the City due to faults located within and nearby the City boundaries such as the Sierra Madre Fault, the Santa Monica- Hollywood-Raymond Fault and the San Andreas Fault. The close proximity of these and other faults are capable of producing earthquakes, foreshocks and aftershocks of significant magnitude and intensity that require a higher order to seismic resilience in building design and construction.
Justification: Geological. The County of Los Angeles region has a vast and complex network of earthquake faults. Some of these faults, like the previously unknown Northridge Fault are blind thrust faults that earth scientists believe are capable of intense ground shaking similar or greater in size than the January 17, 1994 Northridge Earthquake. The random possible location of these blind thrust faults increase the local seismic risk and poses an increasing threat to public safety.
3 #SJGEQI0A0D3KMAv2
Justification: Geological. Areas within the City of Pasadena may have liquefiable soils that have the potential of allowing greater damage to building structures in an earthquake.
Liquefaction is a very destructive secondary effect of strong seismic shaking where a loss of bearing strength occurs along with ground oscillations in the supporting soils.
Just
ification: Topographic. Several existing buildings are located on parcels in the City of Pasadena on hilly terrain with slopes that create grading, drainage, foundation, infrastructure, utility and emergency access challenges.
Just
ification: Climatic and Geological. The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the 1994 Northridge Earthquake. In addition, the region is within a climate system capable of producing major winds, fire and rain related disasters, including but not limited to those caused by the Santa Ana winds and El Nino (or La Nina) subtropical -like weather. This region is especially susceptible to more active termite and wood attacking insects and microorganisms. P rohibition of the use of wood, timber, and deep timber foundation systems, and wood in retaining and crib walls, as well as limit ing prescriptive design provisions in an effort to mitigate potential problems or deficiencies due to the proliferation of wood d estroying organisms and therefore needs to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Building Code and California Residential Code.
Just
ification: Climatic and Geological (Intermodal Shipping Containers). The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The region is further impacted by construction of buildings and structures utilizing tradition construction materials that impact the amount of energy, air quality, greenhouse gas emission and construction waste in the area. The proposed amendment addresses structural designs specific to intermodal shipping containers, reduce environmental impact of unused and unrecycled intermodal shipping containers, and increase sustainability by reducing consumption of traditional construction materials. The proposed modification needs to be incorporated into the code to assure that new buildings and additions to existing buildings utilizing intermodal shipping containers are designed and constructed in accordance with the scope and objectives of the California Building Code and California Green Building Standards Code.
Just
ification: Topographic and Geological. The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast 4 #SJGEQI0A0D3KMAv2
array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. Additionally, the topography within the Los Angeles region includes significant hillsides with narrow and winding access that makes timely response by fire suppression vehicles challenging and difficult. Pr oposed modifications based on Topographic and Geological conditions establishes design parameters to better mitigate and limit property damage that are the results of increased seismic forces which are imparted upon hillside buildings and structures and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Building Code, California Residential Code, and California Fire Code.

17 #SJGEQI0A0D3KMAv2
that it is visible from the street. The permit, construction documents, and plans shall remain readily available on site until final approval has been granted by the building official.

J. Reinspections: A reinspection fee may be assessed for each inspection or reinspection when such portion of work for which inspection is called is not complete or when corrections called for are not made. This section is not to be interpreted as requiring reinspection fees the first time a job is rejected for failure to comply with the requirements of this code, but as controlling the practice of calling for inspections before the job is ready for such inspection or reinspection.
Reinspection fees may be assessed when the inspection record card is not posted or otherwise available on the work site, the approved plans are not readily available to the inspector, for failure to provide access on the date for which inspection is requested, or for deviating from plans requiring the approval of the building official. To obtain a reinspection, the applicant shall file an application therefor in writing upon a form furnished for that purpose, and pay the reinspection fee in accordance with the fee schedule adopted by this jurisdiction. In instances where reinspection fees have been assessed, additional inspection of the work will not be performed until the required fees have been paid.

BASE LEVEL DIAPHRAGM is the floor at, or closest to, the top of the highest level of the foundation.
DIAPHRAGM ANCHORS are assemblies that connect a diaphragm to the adjacent foundation at the uphill diaphragm edge.
DOWNHILL DIRECTION is the descending direction of the slope approximately perpendicular to the slope contours.
FOUNDATION is concrete or masonry which supports a building, including footings, stem walls, retaining walls, and grade beams.
FOUNDATION EXTENDING IN THE DOWNHILL DIRECTION is a foundation running downhill and approximately perpendicular to the uphill foundation.
HILLSIDE BUILDING is any building or portion thereof constructed on or into a slope steeper than one unit vertical in three units horizontal (33.3%). If only a portion of the building is supported on or into the slope, these regulations apply to the entire building.
PRIMARY ANCHORS are diaphragm anchors designed for and providing a direct connection as described in Sections 1613.6.5 and 1613.6.7.3 between the diaphragm and the uphill foundation.
