What the local data means for water damage in Cornelius
Cornelius is one of the fastest-growing Charlotte-metro suburbs tracked here: 35,094 people (2025 estimate), up 11.7% since 2020[3]. The city spans 12.7 square miles at 2,765 residents per square mile (the 1st densest) and sits entirely in Mecklenburg County, served by ZIP code 28031[4].
Cornelius mixes 23% of homes built since 2010 and 8% before 1980[2]: new supply lines and water heaters in one house, aging pipe and original valves in the next — so where a leak starts depends a lot on the address.
One ZIP code covers the whole city: 28031[6].
Nearest of the other suburbs we track: Huntersville (4.6 mi S), Mooresville (8.2 mi N) and Kannapolis (13.2 mi E)[4].
21 flood-insurance claims have come from Cornelius-area ZIP codes (28031) since 1989, and $177,780 has been paid on them (about $16,162 per paid claim)[1]. 2013 was the worst year, with 3 claims. That is the 4th-fewest of the 14 Charlotte-area suburbs we cover; for comparison, Huntersville (19), Mooresville (10), and Kannapolis (64). Most jobs here start inside the house. Of the 21 claims rated in a flood zone, 7 were in FEMA's high-risk areas (zones A or V) and 14 outside them (zones B, C or X)[1][7] — flooding here is not only a high-risk-zone problem.

Before you call: what a restoration crew does first
Shared walls and ceilings: Cornelius homes by building type
39%[2] of Cornelius's homes share walls, floors or ceilings with a neighbour (multi-unit buildings alone: 30%, the 3rd-highest multi-unit share of the 14 Charlotte-area suburbs we cover). Water crosses those lines: in an attached or stacked unit, tell the neighbour and the association or landlord right away, and check whose policy covers which part of the damage.
After detached houses, the biggest group is 10–19 units: 1,388 of 14,956 housing units[2].
