Market Overview
Alton is a historic Mississippi River town of about 25,279 people in Madison County, Illinois, roughly 20 miles north of St. Louis and the anchor of the Great Rivers & Routes tourism region. The city actively regulates short-term rentals under City Code Title 4, Chapter 22, splitting permits into Type A (owner-occupied, owner present during stays) and Type B (non-owner-occupied). Type B units, the kind most investors want, require a non-transferable special use permit approved case-by-case by City Council, are capped at roughly 0.2% of the city’s residential housing stock (about 26 properties citywide), and must sit at least 500 feet apart. The council has been actively enforcing that scarcity: a Type B application at 409 E. 3rd Street was rejected 0-6 in July 2026. On the performance side, StaySTRA tracks Alton’s short-term rental data at the Metro East regional level, shared with Caseyville, Edwardsville, and Millstadt, so the following figures describe the Alton area STR market rather than Alton alone. That regional market averaged a $168.40 ADR and 69.5% occupancy in June 2026, the most recent month tracked, producing $117.07 RevPAR and $3,187 in average monthly revenue. Year over year, occupancy in the Alton area is down 5.1% and revenue is down 4.0%, even as ADR rose 2.6%, a pattern consistent with a market absorbing fewer bookings at a slightly higher rate.

Short-Term Rental Regulations
Alton actively permits and regulates short-term rentals under City Code Title 4, Chapter 22, and the regime is restrictive for non-owner-occupied operators. Units split into Type A, owner-occupied with the owner present during guest stays, and Type B, non-owner-occupied, which requires a non-transferable special use permit approved case-by-case by City Council. As of June 2025, Type B units must sit at least 500 feet apart from other short-term rentals, are capped at roughly 0.2% of the city’s residential housing stock (about 26 properties citywide), must install noise-monitoring devices checked at annual safety inspections, and must provide at least one off-street parking space per bedroom. Owners who live more than 25 miles away must name a local point of contact. Maximum occupancy is 8 guests. The council has enforced the cap in practice: a Type B special use permit application at 409 E. 3rd Street was rejected 0-6 in July 2026. Guests pay the city’s 8% hotel room tax, plus, since July 1, 2025, the Illinois state Hotel Operators’ Occupation Tax of 6% of 94% of gross receipts, both collected through booking platforms. Permit fee amounts and any annual night limits are not published in this dataset. Enforcement here is classified as strict; investors should treat the Type B cap, not market demand, as the binding constraint on new supply.
Market Comparison
Nationally, short-term rentals typically run around 55% occupancy and a $220 ADR. The Alton area’s June 2026 figures, 69.5% occupancy and a $168.40 ADR, show occupancy running well above the national benchmark while ADR runs well below it, a pattern consistent with a lower-cost Midwest secondary market that fills at a high rate rather than commanding premium nightly rates. Property manager market share and per-listing-type performance data are not yet published for this area, so a direct comparison to competing operators is not possible here. The more relevant comparison for Alton specifically is regulatory: unlike many markets where the constraint is demand, Alton’s non-owner-occupied supply is capped by City Council policy at roughly 26 permits citywide, so competitive dynamics here are shaped more by permit scarcity than by market saturation.
