What Marietta's numbers say about electrical

Marietta counts 63,574 residents (2025 estimate), growing at a middle-of-the-pack 4.1% since 2020^[2]. It covers 23.8 square miles (2,673 residents per square mile, the 7th densest), sits entirely in Cobb County, in ZIP codes 30064, 30060, 30062, 30067, 30090^[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.

5 ZIP codes cover Marietta — 30064 (28% of the city's land), 30060 (23% of the city's land), 30062 (17% of the city's land), 30067 (14% of the city's land), 30090 (0% of the city's land)^[5].

The tracked suburbs closest by are Smyrna (6.5 mi S), Kennesaw (6.6 mi NW) and Sandy Springs (10.1 mi E)^[3].

23% of Marietta's housing was built in 1960–1979^[1] — the 4th-highest share of the 15 Atlanta-area suburbs we cover; nearby, Smyrna (18%), Kennesaw (9%), and Sandy Springs (24%). That window includes roughly 1965–1973, when some homes got aluminum branch wiring^[6].

37% of Marietta homes heat with electricity and 61% with gas^[1] — the 7th-highest share of the 15 Atlanta-area suburbs we cover (Smyrna (36%), Kennesaw (30%), and Sandy Springs (46%) nearby). Gas-heated homes often have more panel headroom, but only a load calculation tells.

Within 10 miles of central Marietta: 76 damaging-wind reports and 0 lightning-damage reports in 2016–2025, the latest on Jun 17, 2025^[4].

Ice is the other outage risk: 6 winter-storm, ice or hard-freeze days in 2016–2025^[4] — worth knowing when sizing a generator or asking about whole-home surge protection.

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

Out of the 15 suburbs on this site, Marietta has the fewest lightning-damage reports nearby (0, tied with Newnan)^[4] and the 2nd-lowest share of detached houses (43%)^[1].
