Under most commercial leases—and applicable building codes—the landlord is generally responsible for installing and maintaining fire protection, including smoke detector and sprinkler systems.
But commercial tenants are usually responsible for maintaining smoke and carbon monoxide detectors within their leased premises, including testing the devices regularly and changing the batteries when necessary. Commercial tenants also generally have a responsibility not to obstruct or hinder fire escape routes or to create or maintain fire hazards within the leased premises.
In Wisconsin, commercial landlords are typically responsible for the installation and maintenance of fire protection systems, such as smoke detectors and sprinkler systems, in accordance with commercial leases and applicable building codes. On the other hand, commercial tenants have the duty to maintain smoke and carbon monoxide detectors within their leased spaces. This includes regular testing and battery replacement. Tenants are also responsible for ensuring that fire escape routes are not obstructed and that they do not create or maintain any fire hazards within their leased premises. Compliance with these responsibilities is crucial for both parties to ensure safety and to adhere to legal obligations under Wisconsin's safety regulations and the specific terms of their lease agreements.
