Reading the Grain Valley data for electrical
Grain Valley is one of the fastest-growing Kansas City–metro suburbs tracked here: 16,908 people (2025 estimate), up 8.3% since 2020[2]. On the map that's 6.2 square miles holding 2,744 residents per square mile, the 4th densest of the suburbs here; it sits entirely in Jackson County, with ZIP code 64029[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.
The entire city sits in ZIP code 64029[5].
Nearest of the other suburbs we track: Blue Springs (2.8 mi W), Independence (8.8 mi NW) and Lee's Summit (11.1 mi SW)[3].
