All states have laws (statutes) that require landlords to install and maintain smoke detectors in leased residential premises (apartments, homes).

Some states such as Iowa, Maine, Massachusetts, Ohio, and Vermont require photoelectric or ionization sensors—at least in new construction. And Oregon requires smoke detectors with a HUSH mechanism that allows the alarm to be silenced or temporarily desensitized for 7 minutes while a known condition such as cooking is causing the alarm to activate.

Most states also require landlords to install and maintain carbon monoxide detectors in leased residential premises. Smoke and carbon monoxide detectors are widely available in the same device.

In Ohio, state statutes require landlords to install and maintain smoke detectors in leased residential premises. Ohio law specifically mandates the use of either photoelectric or ionization sensors in smoke detectors, particularly in new constructions. This requirement is in place to ensure that the smoke detectors are effective in detecting different types of fires. Additionally, Ohio law also requires the installation and maintenance of carbon monoxide detectors in residential rental properties. These regulations are designed to enhance the safety of residents by ensuring early detection of smoke and carbon monoxide, which can be life-threatening. It is the responsibility of the landlord to comply with these regulations and ensure that all detectors are in working order for the safety of their tenants.
