How may I request a building address change or the addition of a building number to my building?

Please see the answer to Question 14 under PERMIT SERVICES at the Department of Building Inspection's Frequently Asked Questions Web page.

Why is EAS internal to the city and not generally available on the web?

We would love to change this, but EAS is a business critical application. If we need a new create a new address, and EAS is down, we may not be able to support other business critical operations (issue permits etc). If we expose EAS to the entire web, this introduces risks (such as denial of service attacks) that increase the probability of an outage. Until we receive funded support to mitigate these risks, we will not open EAS to the web at large.

What browsers are supported?

We test the application in Internet Explorer 7 and Firefox 3.6. We don't have the resources to test more than these two - but you can probably safely use Chrome8, Firefox, and Chrome. The best experience will be in Chrome, then Firefox, then Internet Explorer 8.

Is there a geocoding service?

There is, but its not formally available for clients other than EAS itself. We expect to make it available but it's not on the front burner.Yes there is, See this page.

Is it possible to get a "data dump"

...

This feature is specifically identified on pages 6 and 7 of the Enterprise (Citywide) Address System: Master Address Database (MAD) and Address Maintenance Application - Functional Requirements, Business Processes, and Logical System Architecture Image Removed (366 KB) document, though it is not yet implemented. When this feature does get implemented, the data product will very likely be available at DataSF, among other data distribution channels.

In December 2009, an early release of the addresses was made available to the Planning Department. This early release has been made available to a larger audience by Mike Wynne of that department.

Warning
titleNo Support Is Available

Because the EAS itself is not yet in production, the following data sets are provided "as is". No other support is available.

These addresses are available in the following formats:

  1. An ESRI point feature class in a compressed personal geodatabase:
  2. An ESRI polygon feature class in a compressed personal geodatabase:
  3. A PostgreSQL 8.4 database dump, including a PostgreSQL installer for Windows:

Yes it is. See this page.

Why can't I see my apartment?

The "seed data set" that was used to initially populate the database for EAS was from the Address Verification System (AVS) at the Department of Building Inspection (DBI). Apartments are not tracked in AVS. While EAS supports apartment addresses (as well as condos and time shares) there is currently no executive level sponsorship for having these data entered into EAS. The business case behind apartment level addresses is resident notification - but without executive sponsorship, maintenance of apartment level addresses will be ad hoc.

Why are there so few apartment addresses?

See above.

Why is the zip code for my address wrong?

A very small fraction of addresses in EAS will have the wrong zip code. These addresses will generally be near the boundary of the zip code area. Zip codes are not critical for us to deliver services so this is not really an operational issue. When we update our zip codes, we use a data product that is derived (and generalized) from the USPS zip code data. It is the generalization that causes these errors.

EAS opens extra windows, sometimes lots of them. Why won't it use tabs?

If you have this problem you are probably using IE8. If it bothers you, you can "disable protected mode" by doing the following. 

Tools > Internet Options > Security > Security For This Zone > Enable Protected Mode (uncheck)
