Smoke and carbon monoxide alarms are among the most important safety devices in any home—but during inspections across Medford, Grants Pass, Ashland, and throughout Southern Oregon, I often find they are either improperly installed or past their service life.
Understanding both proper placement and replacement timelines—based on IRC (International Residential Code) guidelines—is essential for protecting your home and family.
Where Smoke Alarms Should Be Installed:
Smoke alarms should be located:
• Inside every bedroom.
• Outside each sleeping area (hallways).
• On every level of the home, including basements and habitable attics.
Modern standards recommend interconnected alarms, so when one sounds, they all sound—providing early warning throughout the home.
Carbon Monoxide Alarm Requirements:
Carbon monoxide (CO) alarms are required:
• Outside sleeping areas.
• In homes with fuel-burning appliances.
• In homes with an attached garage.
Because CO is colorless and odorless, proper placement is critical.
Proper Placement & Clearance:
Correct installation helps prevent nuisance alarms and ensures proper function:
• Keep smoke alarms at least 3 feet from bathroom doors with showers/tubs.
• Avoid placing alarms too close to kitchens.
• Follow manufacturer guidelines for ceiling/wall placement.
• Keep clear of vents, fans, and drafty areas.
When Should Alarms Be Replaced?
Even if alarms appear to work, they don’t last forever.
General guidelines:
• Smoke alarms: Replace every 10 years.
• Carbon monoxide alarms: Replace every 5–7 years (or per manufacturer).
• Batteries: Test monthly and replace at least once per year.
Many newer alarms have a manufacture date printed on the back—this is the easiest way to determine age.
Why This Matters in Southern Oregon.
Homes in Jackson and Josephine Counties, especially older properties, often have outdated or improperly installed alarms. This is a simple, low-cost improvement that significantly increases safety.
