What DFW AHJs require this year
- Adopted code editions — most DFW jurisdictions are on the 2021 or 2024 IFC, referencing NFPA 25 (2020 or 2023), NFPA 72 (2019 or 2022), and NFPA 13 (2019 or 2022). Individual amendments vary; Zion tracks each.
- IFC §510 ERCES trigger — most DFW AHJs have adopted the IFC §510 language pulling new construction and some existing buildings into ERCES scope. Local amendments define the exact triggers.
- Permit portals + acceptance-test scheduling — every AHJ has different submittal and inspection workflows. Our permit team knows each one.
- Local amendments to NFPA 25 — a handful of DFW AHJs add stricter inspection cadence or specific report-format requirements.

DFW FAQ
Which DFW fire marshal has the strictest ERCES requirements?
Frisco, Plano, and Dallas each apply IFC §510 aggressively — full grid surveys required on nearly all new construction over 50,000 sq-ft. Fort Worth and Arlington are similar. Smaller suburbs are catching up quickly. Our Building Signal Check reflects the actual local amendment for each DFW AHJ.
Does Zion permit and inspect in every DFW city?
Yes. Our permit team submits fire-alarm and sprinkler drawings across the full DFW AHJ list. We know each city's portal, submittal package requirements, and inspection scheduling process.
