Short Term Rentals in Saint Charles, Missouri: Noise Monitors, STR Inspections, and Licenses after June 15, 2024

A Guide for Property Managers

For residentially zoned properties, no new STR applications have been accepted since June 17, 2023, due to a moratorium that is ending on June 15, 2024. To operate an STR citywide, a Conditional-Use-Permit-2.pdfConditional Use Permit is required, which involves public hearings and City Council approval. Additionally, STR properties must be at least 500 feet apart within residential zones and the total number of STRs is capped at 0.5% of the city’s housing units, approximately 150 units.

The City of St. Charles, Missouri, has implemented Ordinance 22-104, establishing comprehensive regulations for operating Short Term Rentals (STRs). If you are a property manager or owner looking to venture into the short term rental market in St. Charles, Missouri, this guide will help you navigate the requirements to obtain and maintain your STR license, ensuring compliance with all local regulations.

Understanding Short Term Rental Regulations in St. Charles, Missouri

To legally operate a Short Term Rental in St. Charles, you must adhere to the following key requirements:

  1. Short Term Rental Permit: Every STR property must have an approved permit before commencing operations. This permit must be renewed annually and includes a mandatory safety inspection. The city staff will schedule this inspection.

2. Occupancy: STRs are only permitted within the primary structure of the property.

3. Parking: Off-street parking is mandatory, with one parking space required for each bedroom used as an STR.

4. Noise Regulations: No amplified or reproduced sound is allowed outside or audible from the property line between 10:00 PM and 10:00 AM. A noise monitoring device, such as Alertify, must be installed to alert the host of any unreasonable noise levels.

5. Guest Conduct: Property owners or operators must ensure that guests do not create unreasonable noise or disturbances, engage in disorderly conduct, or violate any applicable laws.

Annual Short Term Rental Inspections

To ensure your STR is safe and compliant, an annual inspection is required. Here are some common items inspectors will check:

  1. Smoke Alarms: Must be installed within and outside every bedroom and on every level of the property.
  2. Carbon Monoxide Alarms: Required if there are gas appliances or an attached garage, installed outside all bedrooms.
  3. GFCI Outlets: Bathrooms, kitchen counters, laundry areas, and outdoor outlets must be GFCI protected.
  4. Egress Windows: Necessary for any area converted to a bedroom, meeting specific size requirements.
  5. Noise Monitoring Device: Must be installed and operational. Order here.
  6. Handrails: Required for all steps (indoor and outdoor) with four or more steps.
  7. Permits for Changes: Any undocumented work, such as new bedrooms or kitchen updates, may require a building permit.
  8. Occupancy Limits: Determined based on bedroom size, with a maximum of 10 occupants per property unless additional safety measures are in place. Consider a noise monitor that detects occupancy as well.
  9. Historic Districts: Exterior changes in these areas may need Landmarks Board review.
