What an ECC-Rater Must Do at Your Home: Be There, Measure, Photograph
The rater must be on site and take part in every test, measuring rather than estimating. Helpers may assist only under the rater's direct supervision, and only the rater who did or supervised a test may sign its certificate. Photographs with a time and location stamp are stored by the provider and shared with the Commission on request.

Present and measuring
Section 10-103.3(e)2E says raters shall be present and personally participate in any field verification or test. If they rely on employees, designees or trainees, they must be able to directly monitor and verify that each measurement was done properly. Numbers based on assumptions or averages are presumed untrue unless the Executive Director has given written permission.
Helpers and the signature
A technician who is not a certified rater may test only while directly supervised in person on the project site. No one except the rater who performed, or directly supervised, a test may sign its certificate of verification.
Why the camera comes out
Photographs kept as evidence must show the specific equipment tested or measure verified, include enough background to identify the site, and carry a time and location stamp. They are stored by the provider, made available to the Commission on request, and not issued with the registered certificate. A photo of your furnace data plate is kept as evidence, not issued as part of your paperwork.
What a rater may not do on your site
A rater or rater company may not perform construction work on a project where they are expected to test. Financial ties to the builder are covered in rater independence.
How raters are checked afterwards
- Each rater gets at least one onsite audit a year, less often for those with the Exemplary designation, performed after the rater has left and without telling them.
- A desk audit compares a job with at least 20 of the same rater’s earlier results to catch copied numbers.
- An onsite audit is mandatory when a homeowner complains.
If the visit did not go this way, how to complain about an ECC-Rater sets out the route. Installers can read how to prepare for the ECC-Rater, and the role itself is on what an ECC-Rater does. For the city’s side, see the city inspector page. Our residential reports list the tests a rater will perform.
