Building Signal Check · 60 seconds

Is your building subject to ERCES annual testing?

A guided check across IFC §510 trigger conditions and your local Authority Having Jurisdiction. Probabilistic — not a code determination.

Step 1 of 3 · Address

What's the building address?

Enter the full street address. We use it to look up the local AHJ and code adoption status — we don't share or sell it.

If autocomplete isn't available, type the full address and we'll do our best to identify the jurisdiction.

Step 2 of 3 · Building info

Tell us about the building.

Best estimates are fine — we'll calibrate. Need to look anything up? Most owners use their county appraisal site: Dallas CAD · Tarrant CAD · Collin CAD · Denton CAD · Rockwall CAD.

Step 3 of 3 · Your contact

Where should we send your report?

We'll generate your report instantly, send a copy to your email, and route a flag to our team if your building looks likely to be in scope.

This information is logged with your request. Zion provides building information only to verified owners, agents, design professionals, or AHJ representatives.

By submitting you agree to our Terms of Service and Privacy Notice. You'll see your verdict immediately. The full report is reviewed by a Zion BDA/ERCES technician and emailed to you within one business day.

How this tool works. Zion provides this Building Signal Check as a free educational service. Results are estimates based on the information you provide and our curated database of Texas AHJ code adoption — they do not constitute a code determination, legal opinion, or guarantee of compliance. Final determination is made solely by your local Authority Having Jurisdiction (AHJ).
