Your building got an ERRCS notice. Here is what it means.

ERRCS stands for Emergency Responder Radio Coverage System. Strip away the letters and it means one thing: when firefighters are inside your building, their radios have to work.

Concrete, steel, coated glass and below-ground floors can block radio signals. Most buildings never notice, because residents use cell phones. Firefighters use their own public safety radios, and those can drop out in stairwells, garages and elevator areas.

The fire code says a building needs approved radio coverage inside, measured against the signal outside (IFC 2021 510.1). If the signal inside is already good enough, nothing is installed. If it is not, the building adds equipment, usually called a BDA system (a radio amplifier plus antennas), to carry the signal in (IFC 2021 510.4.2.1).

You may also see ERCES, ERCC or "public safety DAS" in letters and quotes. They describe the same requirement. Our page on the different names maps them.

This is a firefighter-safety rule. During a fire, crews spread out through the building and talk to each other and to the commander outside by radio. A dead spot in a stairwell or garage is a place where a firefighter cannot be heard.

The model code sets the bar at coverage in 95 percent of all areas and 99 percent of critical areas on each floor (IFC 2021 510.4.1). Critical areas are named locally. Miami-Dade's list, for example, includes stair enclosures, elevator lobbies, fire pump rooms and fire command centers (Miami-Dade BDA guidelines).

Ordinary building work can change the signal. In Fort Lauderdale, a city commissioner described a building that failed after it installed high-impact windows (Sun Sentinel via Firehouse, November 2025). Many Florida condos have done exactly that kind of upgrade.

In Florida, the dates come from state law, F.S. 633.202(18). Most of them have already passed.

The date on your notice controls. If you have one, write it down today and count the months.

Some buildings are exempt. Florida exempts (F.S. 633.202(18)(h)):

• one- and two-family homes and townhouses;
• buildings under 12,000 square feet with no underground areas;
• low-rise apartments under three stories with direct exterior exits;
• some wood-frame apartment buildings.

The statute says "apartments"; condominium buildings are normally classed as apartment occupancies. Confirm with your fire marshal. And if the fire marshal finds the public safety signal weak even outside the building, no system or assessment is required (F.S. 633.202(18)(e)).

Not in Florida? Rules and dates are local. Find yours on the requirements pages.

There is no public price list, and nobody can price your building over the phone. The figures we can source come from one news report on Fort Lauderdale high-rises (Sun Sentinel via Firehouse, November 2025):

Those are high-rise numbers from one city. Your building may cost far less, or more. Fire department fees are on top: Miami-Dade, for example, charges $281.48 per inspector per hour for the signal verification and acceptance test (Implementing Order 04-123, effective 10/01/2025). After installation, the system must be tested every year (IFC 2021 510.6.1), so budget for that too.

The only way to a real number is a signal test and written bids on the same scope. Our sister site keeps the full cost breakdown with published fees.

Nothing here has to be decided tonight. Here is a calm order of work for the next few weeks.

1. Find the paper. Collect the notice, any fire marshal letters, old test reports and permits. Deadlines and scope are usually written there.
2. Name one contact. Pick one person, a manager or a board member, to speak for the building. Fire departments, installers and the radio licensee all need one point of contact.
3. Check for an exemption. Run the building checker. It applies Florida's published exemptions and cites each one.
4. Get a signal test. A test shows whether you need a system at all, and how big. Ask for a written report with a floor-by-floor grid.
5. Ask the fire department for its technical criteria. The fire code official keeps a document with frequencies and design requirements (IFC 2021 510.4.2.2).
6. Get written bids on the same scope. Comparable bids are easier to judge. You can request up to 3 quotes.
7. Check credentials. The designer and lead installer need an FCC general radio operator license and in-building system training at minimum (IFC 2021 510.5.3).
8. Get the radio licensee's consent. The agency that owns the radio channels must consent before a booster operates, kept in writing (47 CFR 90.219(b)(1)(i); F.S. 633.202(18)(d) in Florida).
9. Permit, install, pass the acceptance test. A permit is required, and the system is tested floor by floor when it goes in (IFC 2021 510.3 and 510.5.4).
10. Put the yearly test on the calendar and in the budget. The code requires a test every year and after structural changes (IFC 2021 510.6.1). Our sister site sends free test reminders.

How the cost is shared between the association and owners is a legal question for your association's attorney.

• The acceptance test report and the amplifier gain values. The model code says if those records are lost, the owner must rerun the acceptance test (IFC 2021 510.5.4 item 6).
• Every annual test report. San Diego, for example, requires the acceptance report, the annual report from the last 12 months and the city's Authorization to Operate to be available for inspection (SDFD ERRCS guideline, Appendix C).
• The radio licensee's written consent (47 CFR 90.219(b)(1)(i)).
• Permits, as-built drawings and the service contract.

Boards decide better with one page in front of them. The Board Brief prints a single sheet with the rule and its citation, the dates above, the sourced cost figures, the steps in order, and six questions to ask every installer. It stores nothing about you.

When the board is ready for prices, request up to 3 quotes. Your request goes to up to 3 vetted installers who serve your area, so the board can compare bids side by side. We send no texts and make no cold calls. Owners never pay us; installers do.
