How often should smoke detectors be replaced in a rental property?

Smoke detectors are crucial for fire safety, and their reliability can diminish over time. The National Fire Protection Association (NFPA) and many building codes recommend that smoke detectors be replaced every 10 years. This is because the sensors within the smoke detectors can degrade, leading to decreased sensitivity and potential failure to detect smoke effectively.

Replacing smoke detectors every 10 years ensures that they remain functional and provide an optimal level of safety for tenants. Additionally, regular maintenance includes testing the devices monthly and replacing batteries as needed, but these practices do not negate the need for replacing the entire unit after the recommended time frame. It's important for property owners and managers to stay informed about best practices to enhance safety in rental properties.
