Saint Charles, Missouri

Saint Charles, MO is currently at its short-term rental cap and not accepting new residential STR permit applications. The city caps residential STRs at 0.15% of total housing units, roughly 48 units, a limit cut from 0.5% (about 150 units) on April 15, 2025, and the city reports it is at that cap now. New residentially-zoned STRs are permitted only within the Extended Historic Preservation District overlay; anywhere else requires a Conditional Use Permit with public hearings and a City Council vote. Saint Charles is one of the St. Louis metro’s top heritage-tourism destinations, drawing what the local CVB describes as millions of visitors a year to its roughly 10-block historic Main Street district, a National Historic Register area with more than 100 shops, restaurants, and wineries, plus the First Missouri State Capitol, the Lewis and Clark Boat House and Museum, and the riverfront Ameristar Casino. Saint Charles’s STR performance data in StaySTRA’s dataset is tracked at the St. Louis metro regional level, shared with the city of St. Louis, rather than reported uniquely for Saint Charles, so all performance figures below describe the shared St. Louis metro area STR market rather than Saint Charles in isolation. In the most recent tracked month (June 2026), that shared market shows an average daily rate of $168 and occupancy of 69.5%, with average revenue of $3,185 per listing for the month. Year over year, occupancy is down 5.1 percentage points and revenue is down 4.0%, even as ADR is up 3.4%. Bedroom mix, channel split, listing-type counts, and top property manager rosters are tracked at the same shared regional level rather than uniquely for Saint Charles, so this profile omits those figures rather than present a regional total as the city’s own. Housing data is available specifically for Saint Charles: the typical home value was $353,187 as of June 2026, with 280 homes for sale.
