Key Takeaways
St. Charles Airbnb income potential: Market-wide average daily rate is $216.50 with 61% occupancy across 321 active listings — earning an average of $30,100 per year in gross revenue per listing (AirDNA, May 2026). The market scores 98/100 on AirDNA’s Market Score, making it one of the strongest suburban STR markets in the Midwest. A well-managed 2–3 bedroom property can realistically net $17,500–$35,000 annually after operating costs; a 4+ bedroom or premium historic-district property can clear $35,000–$63,000+, but only if you can secure one of the limited permitted addresses or operate in a commercially-zoned location.
St. Charles sits at a rare intersection for short-term rental investors: strong and growing demand, meaningfully constrained supply, and a Main Street historic district that commands ADR premiums 20–25% above the surrounding suburbs. But the numbers alone do not tell the full story — St. Charles also has one of the tightest regulatory environments in the St. Louis metro, with a hard 48-unit residential STR cap that is already full.
This guide breaks down real market data for the St. Charles metro — St. Charles City, St. Peters, O’Fallon, Lake Saint Louis, and Wentzville — covering what properties actually earn, how income varies by property type and season, what your operating costs will look like, and what the regulatory landscape means for new operators in 2026.
We manage short-term rental properties across the St. Charles metro and publish this data because transparent market information helps owners make better decisions — whether they work with us or manage on their own.
Current St. Charles Airbnb Market Data
Market Overview
AirDNA’s MarketMinder tracks 321 active short-term rental listings in St. Charles City as of May 2026, with performance metrics that place the market well above both the broader St. Louis metro and national suburban averages:
- Average daily rate (ADR): $216.50 (+3% year over year)
- Occupancy: 61% (+4% year over year)
- Annual revenue per listing: $30,100
- RevPAR: $120.60 (+6% year over year)
- AirDNA Market Score: 98/100 (“Great”) — Investability 91, Rental Demand 88, Revenue Growth 84, Seasonality 79, Regulation 70
The listing mix is predominantly entire-home rentals (89%), with 56% of properties listed on both Airbnb and Vrbo, 42% on Airbnb only, and 2% on Vrbo only. The bedroom distribution skews toward the middle: 1-bedroom units account for 27% of listings, 2-bedroom 31%, 3-bedroom 21%, 4-bedroom 16%, and 5+ bedroom 5%.
How the Five Submarkets Compare
The St. Charles metro is not a single market — it is five distinct jurisdictions with meaningfully different performance profiles. St. Charles City’s historic Main Street corridor carries a clear ADR premium, while the surrounding suburbs trade lower rates for stronger midweek corporate demand.
| Submarket | Active Listings | ADR | Occupancy | Annual Revenue/Listing | RevPAR |
|---|---|---|---|---|---|
| St. Charles City | 321 | $216.50 | 61% | $30,100 | $120.60 |
| St. Peters | 55 | $177.50 | 65% | $25,500 | $116.70 |
| O’Fallon | 63 | $178.40 | 56% | $23,300 | $101.00 |
| Wentzville | 40 | $171.80 | 58% | $20,700 | $92.60 |
| Lake Saint Louis | — | — | — | — | — |
Lake Saint Louis does not have a standalone AirDNA market page; listings there are absorbed into the Wentzville or O’Fallon data sets. If you own property in Lake Saint Louis, the Wentzville/O’Fallon figures above are the best available proxy.
What drives the St. Charles City premium: the walkable historic Main Street corridor — 10 blocks, 100+ shops and restaurants, multiple wedding venues — plus the Ameristar Casino Resort Spa (which draws over 5.5 million visitors annually) create concentrated demand that the suburbs do not replicate. St. Peters’ higher occupancy rate (65% vs. 61%) reflects stronger midweek corporate bookings from nearby employers like Citi and Mastercard, but the lower ADR means net annual revenue still trails St. Charles City.
Estimated Annual Income by Property Type
Using AirDNA’s $30,100 market average as the anchor and cross-referencing publicly visible Airbnb listings across the metro, here are realistic annual income expectations by property type:
| Property Type | Typical Nightly Rate | Expected Occupancy | Est. Gross Revenue | Est. Net (after ~30% costs) |
|---|---|---|---|---|
| Studio / 1BR | $90–$140 | 55–62% | $18,000–$25,000 | $12,600–$17,500 |
| 2BR | $130–$200 | 58–65% | $25,000–$38,000 | $17,500–$26,600 |
| 3BR | $180–$260 | 58–65% | $35,000–$50,000 | $24,500–$35,000 |
| 4+BR / luxury historic | $260–$450+ | 55–65% | $50,000–$90,000+ | $35,000–$63,000+ |
Important context: these estimates use a 30% operating cost haircut covering cleaning, utilities, supplies, maintenance, platform fees, and insurance — but not management fees. If you use a professional manager (15–25% of gross revenue), adjust your net downward accordingly. The vacation rental management cost guide breaks this math down in detail.
Suburban discount: properties in St. Peters, O’Fallon, and Wentzville should underwrite to 10–30% below the St. Charles City figures above, consistent with the submarket ADR and occupancy differentials in the table. A 3-bedroom in O’Fallon earning $35,000 gross is a reasonable expectation; a 3-bedroom on Main Street St. Charles earning $50,000 is equally reasonable.
Breaking Down Operating Costs
Understanding where revenue goes is critical to calculating true Airbnb income. Here is what St. Charles operators typically face:
Cleaning and turnover: $80–$200 per turnover for a 2-bedroom, $150–$300 for a 3–4 bedroom. Most managers pass cleaning costs through to guests as a separate line item on the listing. Cleaning represents roughly 8–12% of gross revenue.
Utilities: Missouri’s temperature extremes — humid summers above 90°F, sub-freezing winters — push both AC and heating bills. Plan $200–$450/month all-in (Ameren MO electric, Spire gas, water, internet, streaming) for a typical 2–4 bedroom STR. This represents roughly 4–6% of gross revenue.
Insurance: Standard landlord insurance in Missouri averages approximately $1,220/year. STR-specific insurance — which you need, because a standard homeowner’s policy will not cover short-term rental activity — averages $2,000–$3,500/year with $1M+ commercial general liability. Budget $1,500–$3,500 depending on property value and coverage level.
Platform fees: Airbnb’s host-only fee is 3% per booking. Vrbo charges 5% host commission plus a guest service fee. If you list on both platforms (56% of St. Charles hosts do), plan for a blended 3–5% in platform fees.
Property management: Full-service STR management fees in the St. Louis metro range from 15% to 30% of gross booking revenue. We published our own fee structure on our pricing page because most operators in this market do not disclose their rates publicly. At 20–25% management plus 30% operating costs, managed properties retain roughly 45–55% of gross revenue as net cash flow to the owner.
Taxes: The St. Charles STR tax stack is material. In St. Charles City, most residential STR hosts pay approximately 12.95% in combined state, county, and city taxes on each booking — comprising the Missouri state sales tax (4.225%), St. Charles County general sales tax (1.725%), the county sleeping room tax (5%), and city sales tax (~2.0%). Properties that fall under City Code Chapter 620 (generally hotels with more than 8 rooms, not most residential STRs) pay additional city lodging taxes pushing the total to ~14.70%. Airbnb collects the state sales tax and the county sleeping room tax on the host’s behalf; the city taxes must be remitted separately. Vrbo does not collect the county sleeping room tax — Vrbo hosts must remit it themselves.
Typical expense breakdown as a percentage of gross revenue:
- Cleaning and turnover: 8–12%
- Utilities: 4–6%
- Maintenance and repairs: 4–8%
- Supplies (linens, toiletries, etc.): 2–3%
- Platform fees: 3–5%
- Insurance: 2–4%
- Property management (if applicable): 15–25%
Seasonal Income Patterns in St. Charles
AirDNA gives St. Charles a Seasonality score of 79 out of 100 — meaningful month-over-month variation, but better diversified than pure-leisure markets like Branson (which collapses 40+ occupancy points in January–February). Three overlapping demand streams prevent a deep winter trough: corporate travel, Ameristar Casino traffic, and the city’s signature Christmas Traditions event series.
Spring (March–May)
- Wedding season launches at Katy Trail wineries and Main Street venues (Old Stone Chapel, LaBelle Coeur)
- Lewis & Clark Heritage Days draws weekend visitors
- Corporate and relocation travel picks up with the spring hiring cycle
- Occupancy: 60–68%
- Expected monthly revenue: $2,400–$3,500 (2BR)
Summer (June–August)
- Peak family tourism season
- Festival of the Little Hills draws 300,000–350,000 visitors over three days in August — the single largest annual event in the metro
- Ameristar Casino summer concert series
- Katy Trail cycling and Augusta AVA wine-country tourism at peak
- Occupancy: 63–72%
- Expected monthly revenue: $2,800–$4,000 (2BR)
Fall (September–November)
- Oktoberfest at Frontier Park and Legends & Lanterns drive October bookings
- Fall foliage along the Katy Trail and wine-country harvest events
- Cardinals postseason can spike short-notice demand from out-of-town fans (St. Charles is 23 miles from downtown St. Louis)
- Occupancy: 60–70%
- Expected monthly revenue: $2,500–$3,600 (2BR)
Winter (December–February)
- Christmas Traditions on Main Street runs every Friday, Saturday, and Sunday from the day after Thanksgiving through Christmas Eve — the city’s signature differentiator versus every other St. Louis suburb
- Ameristar Casino provides year-round baseline traffic
- Corporate travel slows but does not stop — GM Wentzville, Citi, and Mastercard maintain operations through winter
- January–February is the trough, but occupancy holds above pure-leisure-market collapse
- Occupancy: 48–58%
- Expected monthly revenue: $1,800–$2,600 (2BR)
Annual variation: unlike Branson, where the post-New Year valley can cut revenue to single-digit occupancy, St. Charles maintains a floor driven by corporate demand and year-round casino traffic. Budget conservatively for January–February, but expect the trough to be shallower than in seasonal-dependent markets.
What Drives Airbnb Income in St. Charles
Not all properties in the metro perform equally. These factors separate the top quartile from the average:
Location Within the Metro
- Main Street walking distance: properties within a 5-minute walk of Main Street St. Charles command the 20–25% ADR premium reflected in the submarket table. This is the single strongest pricing lever in the market.
- Ameristar proximity: the casino resort draws 5.5 million visitors annually. Properties that can position themselves as the “Main Street alternative” to the Ameristar hotel capture overflow and groups who want a full kitchen and more space.
- Wine-country adjacency: properties near the Augusta AVA (America’s first officially designated wine region, predating Napa Valley by 8 months) benefit from April–October weekend demand, especially from bachelorette and anniversary-trip bookings.
- Corporate corridor: St. Peters and O’Fallon properties near Citi, Mastercard, and the I-70/I-64 interchange capture midweek corporate stays that offset lower weekend demand.
Property Features
- Full kitchen and living space: entire-home rentals (89% of the St. Charles market) significantly outperform private rooms
- Modern finishes with historic character: renovated Main Street properties that combine period architecture with updated interiors command the highest ADRs
- Outdoor space: patios, decks, and fire pits perform well in the extended Missouri warm season (April–October)
- Workspace: a dedicated desk and strong WiFi appeal to the corporate-travel segment, particularly in the St. Peters and O’Fallon submarkets
Management Quality
- Dynamic pricing: adjusting nightly rates to match demand events — Festival of the Little Hills, Christmas Traditions weekends, Cardinals home games, Ameristar concert weekends — can increase annual revenue 8–15% over flat pricing
- Review velocity: properties with 4.9+ ratings and recent reviews see measurably higher booking rates on both Airbnb and Vrbo
- Multi-platform distribution: 56% of St. Charles hosts list on both Airbnb and Vrbo. Listing on a single platform leaves demand on the table.
- Response speed: the St. Charles market has strong competition for guest attention. Quick communication — ideally under 1 hour — drives conversion from inquiry to booking
How Professional Management Affects Income
The management-fee question matters more in a supply-constrained market like St. Charles because the opportunity cost of underperformance is higher. If your property is one of only 48 permitted residential STRs in the city, every percentage point of lost occupancy or missed ADR optimization represents unrealized value from a scarce asset.
Self-Management Income
- Gross revenue: 100%
- Your time investment: 10–20 hours/week (guest communication, scheduling, cleaning coordination, maintenance)
- Operating costs: 15–20% of revenue
- Net income: roughly 80–85% of revenue
Self-management works well for owners who live in the metro, have flexible schedules, and enjoy the hospitality side of the business. The risk is underpricing — most self-managers leave 8–15% of potential revenue on the table through flat pricing and suboptimal listing optimization.
Professional Management Income
- Gross revenue: 100%
- Management fee: 15–25% of revenue (varies by operator; see our pricing page for published rates)
- Your time investment: 2–4 hours/month
- Operating costs included: cleaning, maintenance, and guest services coordinated by the manager
- Net income: roughly 55–65% of revenue after management fees and operating costs
The math works when professional management recovers more revenue (through dynamic pricing, multi-platform distribution, and optimized listings) than the fee costs. In a market with St. Charles’s seasonality profile, the management fee earns its keep primarily during the high-demand weekends — Christmas Traditions, Festival of the Little Hills, and Ameristar event weekends — when each incremental $20–$40 per night is being applied to the year’s highest occupancy base.

The Regulatory Factor: Why Supply Constraint Matters for Income
St. Charles is not a market where supply and demand reach equilibrium naturally. The regulatory environment deliberately constrains new STR supply, which has direct implications for existing operators’ income stability.
City of St. Charles: 48-unit residential cap. Ordinance 22-104 (as amended April 15, 2025) limits residential-zone short-term rentals to 0.15% of total housing units — which works out to 48 permitted properties. As of May 2026, the City is at the cap and is not accepting new applications for residentially zoned STRs. Commercially zoned properties in the Extended Historic Preservation District are exempt from the cap and may still apply.
St. Charles County Bill 5490. Introduced May 11, 2026, this bill would regulate STRs in unincorporated St. Charles County — primarily affecting wine-country and rural properties outside municipal limits. Provisions include a 600-foot buffer between STRs, occupancy caps tied to bedrooms, vehicle parking limits, and licensing with fines up to $500 for unlicensed operation. The bill was scheduled for final passage on May 26, 2026; check sccmo.org/AgendaCenter for the latest status.
Adjacent municipalities. St. Peters, O’Fallon, Lake Saint Louis, and Wentzville do not currently have STR-specific ordinances. Properties in these cities operate under standard rental-occupancy permits, general business licenses, and zoning. This regulatory openness represents both opportunity (easier market entry) and risk (no cap means new supply can enter freely).
For the full jurisdiction-by-jurisdiction regulatory breakdown — including the Missouri state tax stack, county sleeping room tax, city license taxes, and HOA-layer considerations — see our St. Charles MO short-term rental regulations guide.
What this means for income: in a capped market, existing permit holders enjoy a structural moat. New demand flows into a fixed supply pool, supporting ADR and occupancy growth. The 3–5% year-over-year improvement in ADR and occupancy documented above is partly a consequence of this supply constraint — and it means income projections for current operators are more durable than in open-supply markets.

Comparing St. Charles to Other Markets
How does St. Charles stack up against the other metros where we manage properties?
| Metric | St. Charles, MO | Bentonville, AR | Branson, MO |
|---|---|---|---|
| Average ADR | $216.50 | $203 | $252 |
| Average occupancy | 61% | 57% | 47% |
| Annual revenue/listing | $30,100 | ~$28,000 | ~$30,500 |
| RevPAR | $120.60 | ~$105 | ~$108 |
| Primary demand driver | Historic district + casino + corporate | Walmart corporate + Crystal Bridges | Tourism + shows + outdoor |
| Seasonality risk | Moderate (79/100) | Moderate | High (winter collapse) |
| Supply constraint | Hard cap (48 units) | None | None |
St. Charles’s combination of strong ADR, solid occupancy, moderate seasonality, and supply constraint makes it arguably the most favorable risk-adjusted STR market of the three. Branson has higher peak-season upside but carries significantly more winter risk; Bentonville has strong corporate-driven consistency but faces open-supply competition.
