Live St. Charles listings updated daily from the MLS — plus what local buyers should know before making a move.
New construction in St. Charles is scarce by design — the town is largely built out — which makes the active projects worth knowing precisely. D.R. Horton’s Charlestowne Lakes is delivering three-story townhomes on the east side from $360,990 to $506,990. Pulte’s Ninth Street Commons townhomes are in pre-sale near downtown. Keim Corp’s Corron Estates is coming to the far west side. And Airhart’s Munhall Glen — 50 detached homes with HOA-maintained lawns — is down to its final home. When supply is this thin, builder relationships and timing decide who gets what.

Active listings pulled directly from the MLS.
Charlestowne Lakes townhomes run 1,651+ square feet with 2–3 bedrooms across three stories, with attached garages, near the Von Maur corridor. Ninth Street Commons will add Pulte townhome collections at 315 9th Street with pricing to be announced. Corron Estates positions custom-scale homes in the Corron Farm area of the west side. Expect 2026 buyers to weigh new-build pricing against near-new resales — a comparison we run constantly.
The east side is where new construction actually delivers in 2026, and the Charlestowne corridor is its center of gravity. The former mall site nearby is being marketed for redevelopment, which makes this the part of town most likely to look different in five years — relevant to both upside and construction-period realities. On the west side, Corron Estates extends the estate-lot tradition; expect a different buyer, price point, and timeline entirely.
Builder contracts are not resale contracts: earnest money structures, escalation clauses, and included-versus-upgrade specs all deserve representation, and the builder’s sales office works for the builder. Our buyer representation costs you nothing and typically returns multiples in negotiated incentives — rate buydowns, closing costs, design credits. Register us as your agent on your first visit; builders require it.
With Munhall Glen effectively sold out and Ninth Street Commons not yet priced, today’s decisions are really about Charlestowne Lakes inventory homes versus to-be-built units versus resale alternatives. Quick-move-in homes carry the best negotiating leverage, especially at quarter-end. We track D.R. Horton’s inventory and incentive calendar continuously.
