Most buildings over 12,000 sq ft, all high-rises (>75 ft), and many multi-story commercial, hospitality, healthcare, and multi-family properties now require periodic professional grid testing under Florida Statute §633.202(18) and the Florida Fire Prevention Code.
Local AHJs (Orlando Fire Dept, Osceola County Fire Rescue, Seminole County) are actively enforcing it.
1. Legal Foundation (Simple Version)
Florida law requires minimum radio signal strength for first responders in all new and existing buildings unless specifically exempted.
- Professional grid test (BDA/ERRCS/DAS survey)
- Installation of BDA or DAS if coverage fails
- Ongoing testing once a system is installed
2. Quick Comparison: Exempt vs. Likely Requires Testing
| Category | Examples | Likely Requires Grid Test? | Notes / Frequency Cap |
|---|---|---|---|
| High-Rise Buildings | Condos, apartments, offices, hotels >75 ft | Yes | Every 3 years max |
| Large Buildings | Any building >12,000 sq ft gross | Yes (especially with underground areas) | Every 3 years max |
| Multi-Story Multi-Family | 4+ story apartments/condos | Usually Yes | Check size + construction |
| Hospitality | Hotels, resorts, extended-stay (multi-story or large) | Usually Yes | High priority for chains & independents |
| Healthcare & Senior Living | Hospitals, medical office buildings, assisted living (large facilities) | Usually Yes | Critical areas require extra attention |
| New Construction / Major Reno | Any project needing Certificate of Occupancy | Yes | AHJ Accepted Testing required |
| Small / Low-Rise Exempt | 1–2 family homes, townhouses, <12k sq ft with no underground areas | No | Generally exempt |
3. Buildings That Typically Need Testing
4. Testing Frequency
| Building Type | Grid Assessment Frequency (Max) | Installed System Testing |
|---|---|---|
| High-Rise + Buildings >12,000 sq ft | Every 3 years | Annual recertification |
| Other existing buildings | Every 5 years | Annual (if system installed) |
| New Construction | AHJ Accepted Testing (one-time) | Annual after install |
| Any building with installed BDA/DAS | Per 3-year cycle | Annual required |
5. What Counts as a Passing or Failing Score?
AHJs score in-building radio coverage with Delivered Audio Quality (DAQ). Here is what those numbers mean in plain language.
Speech is generally intelligible with little to no effort. Messages are understood on the first try.
Speech is distorted or incomplete. Responders have to repeat themselves or ask for clarification.
Recommended Next Steps for Building Owners & Managers
- 1. Confirm whether your building size, height, or use type typically triggers testing under Florida fire code.
- 2. Download the free Central Florida ERRCS Compliance Checklist to see what AHJs usually look for.
- 3. Schedule a professional grid test before an inspection or CO deadline, not after a failed notice.
- 4. If a BDA/DAS is already installed, plan for required annual recertification so coverage stays documented.
