Missouri Renters: Smoke Alarm Laws & Tenant Responsibilities

Missouri renters have the right to a safe home, and that includes reliable smoke alarms. Understanding your responsibilities and what your landlord must provide helps keep your household safe and prevents disputes. This guide explains Missouri's smoke detector laws — and what steps you should take if there are issues.

What Are Missouri’s Smoke Alarm Requirements?

Missouri law requires operational smoke alarms in certain types of rental properties to help prevent fire-related injuries. The rules vary depending on the property’s age and location. Always check your lease or talk to your landlord about the exact responsibilities for your unit.

• Landlords must install and maintain smoke detectors when required by state and local law.
• Most cities (like Kansas City and St. Louis) require smoke alarms in every rental unit, regardless of age.
• Missouri state law (Section 320.083 RSMo.) requires smoke detectors in certain residential dwellings, such as new constructions since 2001 and multi-family buildings.^[1]
• Check with your city or county’s housing department for local ordinances that may require more stringent rules.

Where Must Smoke Alarms Be Placed?

According to most Missouri city codes and Section 320.083 RSMo., smoke detectors should be placed:

• Outside each sleeping area (like hallways near bedrooms)
• On every occupied level of the home
• In the basement (if present)

What Are Tenant Duties for Smoke Alarms?

Renters have a legal duty to keep smoke alarms in working order once installed, unless otherwise agreed in your lease. That means:

• Testing devices periodically
• Replacing batteries (if battery-operated and not hardwired)
• Not disabling or removing smoke alarms
• Promptly telling your landlord or property manager if an alarm is missing, damaged, or isn’t working correctly

What Should You Do If No Alarm Is Installed or It’s Broken?

If your rental unit is missing required smoke detectors or one is not working:

• Notify your landlord promptly, in writing if possible.
• Keep a copy of your request for your records.
• If the landlord does not respond, you can contact your city or county housing inspector.

City or county housing authorities (for example, St. Louis City Housing Conservation or Kansas City Code Enforcement) enforce local housing safety codes, including smoke detector rules.

Official Forms: Housing Code Complaint

Missouri does not have a statewide form for reporting smoke alarm violations. However, most cities provide a form or online system for making a housing code complaint if your landlord will not fix missing or broken detectors. For example:

• Kansas City Housing/Code Complaint Form: Use if your landlord refuses to install or repair smoke alarms in your Kansas City rental.
  Kansas City 311 Housing Code Complaint.
• St. Louis Citizen Service Bureau: To report housing safety violations, including smoke alarms.
  St. Louis File a Housing Complaint.

How it works: Use these complaint forms if your landlord will not respond to your written request about missing or broken smoke alarms. After submitting, a city inspector may schedule a visit and can order the landlord to bring the property up to code.

Which Tribunal Handles Rental Disputes?

In Missouri, residential tenant-landlord disputes are handled in local Circuit Courts. These courts deal with claims about housing conditions and lease violations. For more serious or unresolved code issues, tenants can also contact their city’s housing code enforcement agency.

Missouri rental law is mainly governed by the Missouri Landlord-Tenant Law (Chapter 441 RSMo.).^[2]

Summary

Missouri landlords must provide smoke detectors where legally required, and tenants need to maintain them and report problems. Use local complaint forms if your landlord doesn’t respond. Familiarize yourself with your city’s rules for the most protection.
