What Lake St. Louis's numbers say about electrical

Lake St. Louis is one of the fastest-growing St. Louis–metro suburbs tracked here: 19,129 people (2025 estimate), up 14.4% since 2020[2]. It covers 8.6 square miles (2,233 residents per square mile, the 10th densest), sits entirely in St. Charles County, in ZIP code 63367[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.

The entire city sits in ZIP code 63367[5].

The tracked suburbs closest by are O'Fallon (3.4 mi E), Wentzville (5.2 mi NW) and St. Peters (9.8 mi E)[3].

19% of Lake St. Louis's housing was built in 1960–1979[1] — the 6th-lowest share of the 15 St. Louis–area suburbs we cover; nearby, O'Fallon (6%), Wentzville (4%), and St. Peters (23%). That window includes roughly 1965–1973, when some homes got aluminum branch wiring[6].

35% of Lake St. Louis homes heat with electricity and 63% with gas[1] — the 2nd-highest share of the 15 St. Louis–area suburbs we cover (O'Fallon (27%), Wentzville (34%), and St. Peters (29%) nearby). Gas-heated homes often have more panel headroom, but only a load calculation tells.

Within 10 miles of central Lake St. Louis: 49 damaging-wind reports and 0 lightning-damage reports in 2016–2025, the latest on Jul 6, 2025[4].

Ice is the other outage risk: 12 winter-storm, ice or hard-freeze days in 2016–2025[4] — worth knowing when sizing a generator or asking about whole-home surge protection.

10% of Lake St. Louis's housing is from 2020 or later[1] — new enough that builder warranties still apply to many electrical defects.

Measured against the 15 suburbs on this site, Lake St. Louis records the fewest lightning-damage reports nearby (0, tied with 6 other suburbs)[4].
