What the local data means for electrical in Katy

Katy is one of the fastest-growing Houston-metro suburbs tracked here: 28,373 people (2025 estimate), up 29.7% since 2020^[2]. It covers 15.3 square miles (1,856 residents per square mile, the 9th densest), spans Harris County and Fort Bend County and Waller County, in ZIP codes 77493, 77494^[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.

Katy is split across 2 ZIP codes: 77493 (52% of the city's land), 77494 (47% of the city's land)^[5].

Nearest of the other suburbs we track: Rosenberg (16.7 mi S), Sugar Land (18.5 mi SE) and Missouri City (24.1 mi SE)^[3].

16% of Katy's housing was built in 1960–1979^[1] — the 6th-lowest share of the 15 Houston-area suburbs we cover; nearby, Rosenberg (18%), Sugar Land (11%), and Missouri City (25%). That window includes roughly 1965–1973, when some homes got aluminum branch wiring^[6].

35% of Katy homes heat with electricity and 63% with gas^[1] — the 3rd-lowest share of the 15 Houston-area suburbs we cover (Rosenberg (56%), Sugar Land (29%), and Missouri City (39%) nearby). Gas-heated homes often have more panel headroom, but only a load calculation tells.

Within 10 miles of central Katy: 17 damaging-wind reports and 2 lightning-damage reports in 2016–2025, the latest on May 16, 2024^[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.

11% of Katy's housing is from 2020 or later^[1] — new enough that builder warranties still apply to many electrical defects.

Among the 15 suburbs tracked here, Katy stands out for the 3rd-highest share of detached houses (85%)^[1] and the 3rd-highest median home value ($401,700)^[1].
