San Francisco Enterprise Addressing System

3 Years of Enterprise Address System (EAS) at the City and County of San Francisco

It’s been over three years since, with Farallon’s help, San Francisco’s Department of Technology (SFDT) went live with their implementation of the Enterprise Address System (EAS) in February of 2012. EAS was originally built by a team of developers from SFDT and Farallon Geographics between 2010 and 2012 to be an open source, purpose-built enterprise system for maintenance and storage of address data particularly targeting local and regional governments.

In the following years, the team has continued to develop and improve the product in response to customer feedback and evolving technologies. The result has been a product that has managed to serve the SF enterprise in a variety of departments as well as one that has been redeployed for a number of other neighboring municipalities such as the City of Walnut Creek EAS and Tulare County EAS.

At the City and County of San Francisco, the EAS software and data have been used by a variety of departments to help get business done:

  • Department of Technology uses EAS data to supplement their existing city-wide GIS
  • Department of Building Inspection use the EAS software to update and maintain address data so that they can do the job of managing building permits across the city more quickly and easily
  • Department of Public Works use EAS data to supplement their internal data resources
  • Treasurer & Tax Collector use EAS data to supplement their property tax resources
  • Department of Public Health uses EAS data and services to validate their address data for complaint response and enforcement
  • San Francisco Fire Department use EAS data and services to enhance internal web-based applications and services

In addition, SF EAS has data published nightly to the SF OpenData website which is freely available to the public for general use. The EAS code base is open source, and can be found on BitBucket.
