• 8 kept records list an extinguisher branch licence.

What stands out here

Two kinds of state record make up this list. 40 firms show as Licensed and 32 as Registered, so 44 percent of the sample sits in the second group.

Alarm contractors sit on a separate state list, and 122 alarm firms from these counties are kept off the count. That alarm list alone is larger than this whole sample of 72.

Extinguisher and hood work is the bigger trade at 47 firms; 35 hold a sprinkler licence and 10 hold both. Davidson County accounts for 34 of the 72, and Nashville addresses for 24.

The list thins fast beyond Davidson County. Rutherford County, next in line, has only 9 firms and Williamson County has 7, while 5 counties inside the area have no licensed fire firm at all. Murfreesboro leads the towns beyond Nashville with 7, and 10 of the 22 towns named have just one firm. It took 1,020 state records to arrive at these 72.

From 1,020 raw names to 72 companies

1,020 licence records read, 14 folded as a second licence of one firm, 934 set aside as expired, personal or outside the 14 counties.

What counts as a firm here

A firm counts here if it holds a current state firm licence for fire extinguishers and kitchen hood systems, or for fire sprinkler systems, with an address in one of the 14 counties of the Nashville metro area, Tennessee. Individual technicians and expired licences are left out, and a branch licence folds into its firm.

Alarm contractors are left out: 122 active alarm companies sit in these counties, but their licence does not say whether they install fire alarms or burglar alarms.

How to read this

• One amber square per firm: Davidson has the longest row at 34, Cheatham the shortest at 1.
• All 72 are marked owner not yet identified on November 10, 2026. Unknown does not mean independent.

What has not been done yet

• No ownership research on the 72 firms, no website read, no revenue or owner age.
• No street address on the records, so 14 duplicate licences were folded by firm name.
