Independent ERRCS reference
Does your building need an emergency responder radio system?
Fire codes require many buildings to carry firefighter radio signals inside. We show you which rules apply to your building, where each rule comes from, and what to do next.
What you can do here
- Check one building. Answer a few questions about size, height, use and basements. The checker tells you what the published rules say for your jurisdiction, with the code section and source behind each line.
- Read your local rules. Each requirements page lists signal levels, test steps, permit steps and deadlines from your fire marshal's own documents, with the date we last verified them.
- Get quotes, if you want them. The quote request goes to up to 3 vetted installers who serve your area. We tell you that up front, and we never text or cold-call you.
How we keep it honest
We read primary sources: statutes, adopted fire codes and fire marshal guidelines. If a jurisdiction has not published a rule, the page says "not published; confirm with the fire marshal" instead of filling the gap with a guess. Every page shows when it was last verified, and every change goes in the public changelog.
Start with Florida
Florida is our first state. The Florida page explains the statewide law, F.S. 633.202(18), including who is exempt and the high-rise deadlines. County pages such as Miami-Dade County add the local signal and permit rules.
Latest changes
We re-check sources on a schedule and log every change.
| Date | Change | What changed | Page |
|---|---|---|---|
| Fix | Checker: Florida apartment exemptions now apply to condominiums F.S. 633.202(18)(h)3 and (18)(h)4 exempt certain low-rise and wood-frame "apartments". Condominium buildings are normally classed as apartment occupancies, so the checker now applies both exemptions to condos, with a note to confirm with the fire marshal. | Check your building against the published ERRCS rules | |
| Fix | Checker: statutory exemptions are no longer overridden on unverified local pages Where a city's own documents are not verified, the checker used to answer "test needed" even for homes and small buildings the statute exempts. A statewide exemption now settles the answer, because F.S. 633.202(18)(i) bars stricter local rules. | Methodology | |
| Fix | Miami-Dade: elevator shaft rule completed Elevator shafts are critical areas in buildings of six stories or more, and also in shorter buildings that lack signal outside the shaft (MDFR General Guidelines (D)). The page had only the first half. | Miami-Dade County | |
| Updated | NFPA 1225 guide: key numbers from the standard itself Added the 2022 edition's coverage, DAQ, secondary power and annual test requirements from NFPA 1225 Chapter 18 and section 20.3.10, as posted by the Georgia Office of Insurance and Safety Fire Commissioner. | NFPA 1225 and in-building radio systems | |
| Verified | Source notes for Florida, Jacksonville, Fort Lauderdale and Los Angeles The proposed 9th edition text now cites the June 15, 2026 draft amendments. Jacksonville's only published copy is noted as third-party hosted and older than the 2020 statute amendments. Fort Lauderdale's Fire Prevention Bureau page was re-read in a browser. Los Angeles values are marked as based on Requirement #105 (2018). All statute links now point to the 2026 Florida Statutes. | Florida |
Questions people ask
Is ERRCSCheck a government website?
No. ERRCSCheck is an independent reference run by WhenLeads, a division of DV8 WEB LLC. We link every rule to the government or code document it came from so you can check it yourself.
Is the building checker free?
Yes. The checker and every requirements page are free for owners, boards and managers. Installers pay us for alerts and quote requests.
What is the difference between ERRCS and a BDA system?
ERRCS is the code term for the whole in-building radio coverage system. A BDA (bi-directional amplifier) is the main piece of equipment in most of them, so people use "BDA system" for the same thing.
