San Francisco Slope & Seismic Hazard Zone Protection Act
The San Francisco Department of Building Inspection’s Slope and Seismic Hazard Zone Protection Act ("SPA", last update 2025) requires that geotechnical reports for certain hillside projects that fall within certain mapped hazard areas be prepared by a licensed engineer and licensed geologist, and are subject to third party peer review. Murray Engineers, Inc. staff includes both licensed engineers and geologists with experience performing investigations, preparing reports, and with the peer review process for such properties. For greater understanding of Slope and Seismic Hazard Zone Protection Act criteria and requirements, we have included the information below available through SFDBI. We note that the determination of whether a project is subject to Slope Protection Act requirements is ultimately the purview of the plan checker at SFDBI.
