What the local data means for plumbing in Lawrenceville

Lawrenceville is one of the fastest-growing Atlanta-metro suburbs tracked here: 32,822 people (2025 estimate), up 7.1% since 2020[2]. It covers 13.8 square miles (2,379 residents per square mile, the 10th densest), sits entirely in Gwinnett County, in ZIP code 30046[3].

With 12% of homes built since 2010 and 30% before 1980[1], Lawrenceville's plumbing runs from brand-new supply lines and fixtures to aging pipe, original valves and water heaters past their rated life.

The entire city sits in ZIP code 30046[6].

Nearest of the other suburbs we track: Duluth (9.7 mi W), Johns Creek (13.3 mi NW) and Alpharetta (18.0 mi NW)[3].

30% of Lawrenceville's 11,161 housing units predate 1980 and 12% went up in 2010 or later[1] — the 3rd-highest pre-1980 share of the 15 Atlanta-area suburbs we cover; nearby, Duluth (12%), Johns Creek (4%), and Alpharetta (8%) predate 1980. Houses that old can still have galvanized supply pipe or cast-iron drains — especially the 5% built before 1960.

The biggest single slice — 24% — was built 1980 to 1989, and the median home dates to 1988[1]. Neighbours from the same era tend to hit the same plumbing problems at the same time.

Water from the sky is plumbing work too: 8 flood or flash-flood reports within 10 miles over 2016–2025[4], and FEMA logged 11 flood-insurance claims across Lawrenceville's ZIPs[5]. Homes that take water need working drainage, sump pumps and backflow prevention.

53% of homes heat with utility gas, and 53% of households rent[1]. Tenants: report plumbing failures to the landlord in writing.

Out of the 15 suburbs on this site, Lawrenceville has the highest renter share (53%)[1], the 3rd-highest pre-1980 housing share (30%)[1], the 3rd-oldest housing (by median year built) (1988)[1], and the 3rd-fewest flood reports nearby (8, tied with Peachtree City and Kennesaw)[4].
