Use this online form to provide information about your building and fulfill the requirements of San Francisco’s Concrete and Rigid-Wall-Flexible-Diaphragm (RWFD) Building Screening Program (SF Existing Building Code Chapter 5G).

Property owners are welcome to provide basic information about their building, but a California-licensed design professional is required to submit the structural information.

The information you provide will identify if you have a rigid-wall-flexible-diaphragm (RWFD) building, a concrete building, or neither. It will also enable the City to develop an inventory of buildings to evaluate San Francisco’s earthquake risk and seismic requirements.

You may be asked to provide building information, including:

• Details about the structure and design, including ASCE 41 model building type.
• Information about past seismic retrofits and building uses.
• Information about building permits, construction plans and structural design details.

Property owners with more than one building on a parcel need to submit a screening form for each building included in the Concrete and RWFD Building Screening Program. Contact dbi.concrete@sfgov.org for directions on how to submit additional screening forms for additional buildings on a parcel.
