What the local data means for electrical in Baytown

Baytown counts 86,561 residents (2025 estimate), growing at a middle-of-the-pack 1.2% since 2020^[2]. On the map that's 40.0 square miles holding 2,164 residents per square mile, the 6th densest of the suburbs here; it spans Harris County and Chambers County, with ZIP codes 77521, 77520, 77523^[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.

Baytown is split across 3 ZIP codes: 77521 (47% of the city's land), 77520 (38% of the city's land), 77523 (15% of the city's land)^[5].

Nearest of the other suburbs we track: La Porte (8.3 mi SW), Pasadena (13.4 mi SW) and League City (20.8 mi SW)^[3].

28% of Baytown's housing was built in 1960–1979^[1] — the 7th-highest share of the 15 Houston-area suburbs we cover; nearby, La Porte (33%), Pasadena (33%), and League City (12%). That window includes roughly 1965–1973, when some homes got aluminum branch wiring^[6].

60% of Baytown homes heat with electricity and 38% with gas^[1] — the 3rd-highest share of the 15 Houston-area suburbs we cover (La Porte (47%), Pasadena (50%), and League City (41%) nearby). All-electric panels carry the heaviest loads, so EV chargers here usually start with a load calculation.

Within 10 miles of central Baytown: 17 damaging-wind reports and 1 lightning-damage report in 2016–2025, the latest on Mar 24, 2025^[4].

Ice is the other outage risk: 4 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 Baytown'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, Baytown has the fewest lightning-damage reports nearby (1, tied with Galveston and Texas City)^[4] and the lowest median home value ($197,300)^[1].
