Check My Building

Tell us about your building.

There is no charge. In less than 72 hours you get a free DAS Necessity Score: an emergency-radio result and a general result for cell phones. If we need more information first, we say what is missing.

The building

Where it is, where the project stands and what needs to work inside.

An early project without a street address is fine.

Project stage Required

What needs to work inside? Required

Phones and emergency radios are evaluated separately. If the fire code requires emergency-radio coverage, that still applies if you only ask about phones.

What the radio test checks

Run the test on a sample floor.

The emergency-radio test splits each floor into 20 areas and checks each one. Tap an area to test it. Then apply the changes and test again. During design, we predict how each floor of your building would do on this test.

Tap an area to test it

Illustrative · not a prediction

In this sample, an area passes when at least half of it reads Fair or better. The required test checks one spot near the center of each area. Under the International Fire Code, a floor passes when at least 19 of its 20 areas pass (95%), with 99% in critical areas such as exit stairs and elevator lobbies. Local amendments can differ. Phones have no code test; the same grid is shown for comparison.
