If you are asking who installs smoke detectors, start with a licensed electrician for any hardwired units. Many local building codes require hardwiring in new homes, so electrical licensing and code knowledge matter. DIY electrical work risks shocks, electrocution, damage, or accidental fires. For battery-operated detectors, a handyperson or a home security pro can help. When hiring a pro, confirm licensing and familiarity with local codes.

Proper placement and interconnection help detectors alert your household in a fire. An electrician also verifies everything is up to code and working correctly after installation.

Handypeople and home security pros can install battery-operated smoke alarms and place them where they will perform well. Hardwired smoke detector installation should be done by a licensed electrician. If you’re not comfortable with installation or want to ensure everything is done safely, you might want to consider a handyman near you to handle the job efficiently and according to code. A security pro can also add alarms to your broader system for whole-home alerts. In some communities, local fire departments or the American Red Cross may offer free installation and safety education. During visits, ask about maintenance, replacement timing, and indicator lights.
