What Liberty Hill's numbers say about electrical
Liberty Hill is one of the fastest-growing Austin-metro suburbs tracked here: 13,317 people (2025 estimate), up 276.6% since 2020[2]. It covers 4.6 square miles (2,874 residents per square mile, the 4th densest), sits entirely in Williamson County, in ZIP code 78642[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.
One ZIP code covers the whole city: 78642[5].
Nearest of the other suburbs we track: Leander (6.7 mi SE), Cedar Park (11.8 mi SE) and Georgetown (12.3 mi E)[3].
Only 2% of Liberty Hill's housing dates from 1960–1979[1] (the 3rd-lowest share of the 15 Austin-area suburbs we cover; nearby, Leander (2%), Cedar Park (5%), and Georgetown (6%)), so aluminum-era wiring[6] is a minor issue; capacity — panel space, circuits, EV chargers — is the bigger one.
74% of Liberty Hill homes heat with electricity and 20% with gas[1] — the 3rd-highest share of the 15 Austin-area suburbs we cover (Leander (41%), Cedar Park (43%), and Georgetown (49%) nearby). All-electric panels carry the heaviest loads, so EV chargers here usually start with a load calculation.
Within 10 miles of central Liberty Hill: 12 damaging-wind reports and 3 lightning-damage reports in 2016–2025, the latest on Mar 21, 2022[4].
Ice is the other outage risk: 23 winter-storm, ice or hard-freeze days in 2016–2025[4] — worth knowing when sizing a generator or asking about whole-home surge protection.
34% of Liberty Hill'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, Liberty Hill stands out for the 3rd-lowest share of homes built 1960–79 (2%)[1].
