What Brentwood's numbers say about electrical

Brentwood is one of the most established suburbs tracked here — 45,313 people (2025 estimate), down just 0.1% since 2020[2]. The city spans 42.2 square miles at 1,075 residents per square mile (the 13th densest) and sits entirely in Williamson County, served by ZIP code 37027[3].

New construction arrives with 200-amp panels and room to grow; the older homes nearby are the ones where panels fill up, double-taps appear, and an EV charger triggers a load calculation.

37027 is the city's single ZIP code[5].

The closest tracked neighbours are Nolensville (6.1 mi SE), Franklin (7.2 mi SW) and La Vergne (12.0 mi E)[3].

21% of Brentwood's housing was built in 1960–1979[1] — the 4th-highest share of the 13 Nashville-area suburbs we cover; nearby, Nolensville (6%), Franklin (8%), and La Vergne (13%). That window includes roughly 1965–1973, when some homes got aluminum branch wiring[6].

26% of Brentwood homes heat with electricity and 73% with gas[1] — the lowest share of the 13 Nashville-area suburbs we cover (Nolensville (29%), Franklin (49%), and La Vergne (82%) nearby). Gas-heated homes often have more panel headroom, but only a load calculation tells.

Within 10 miles of central Brentwood: 249 damaging-wind reports and 13 lightning-damage reports in 2016–2025, the latest on Dec 18, 2025[4].

Ice is the other outage risk: 28 winter-storm, ice or hard-freeze days in 2016–2025[4] — worth knowing when sizing a generator or asking about whole-home surge protection.

2% of Brentwood's housing is from 2020 or later[1] — new enough that builder warranties still apply to many electrical defects.

Measured against the 13 suburbs on this site, Brentwood records the highest median home value ($1,031,300)[1], the 2nd-most lightning-damage reports nearby (13)[4], and the 2nd-highest share of detached houses (88%)[1].
