Electricians often charge less per unit when you hire them to install multiple smoke detectors in the same visit.
Hardwired smoke detector installations that require running new electrical wiring or installing new circuit breakers may take longer than average.
Some manufacturers now offer smoke detectors with a sealed 10-year battery so you don't have to worry about replacing the batteries manually every year.
Ionization smoke detectors
Ionization smoke detectors are generally the least expensive option at about $10 to $40 per unit before labor. They use a small amount of radioactive material to ionize the air between two electrically charged plates. When smoke enters the chamber, it disrupts the ionization and triggers the alarm.
These detectors are more responsive to fast-flaming fires but may be slower to detect smoldering fires.
Photoelectric smoke detectors
Photoelectric smoke detectors cost $20 to $70 each and use a light beam and a light sensor in a sensing chamber. When smoke enters the chamber, it scatters the light, which then hits the sensor and triggers the alarm. These detectors are more effective at detecting smoldering fires, which often occur in bedding or upholstery.
Using photoelectric smoke alarms near the kitchen and bathrooms reduces nuisance alarms.
Dual-sensor smoke detectors
Dual-sensor smoke detectors cost $40 to $100+ each on average before installation. Dual-sensor detectors combine ionization and photoelectric technologies in a single unit. This provides comprehensive protection against both fast-flaming and smoldering fires, making them a popular choice for overall fire safety even at their higher price point.
Smart smoke detectors
Smart smoke detectors cost $50 to $150+ per unit before labor. These devices are the most advanced and typically the most expensive option. They can connect to your home's Wi-Fi network, allowing you to receive alerts on your smartphone when the alarm is triggered.
Many smart detectors also offer additional features like voice alerts, self-testing capabilities, and integration with other smart home devices. While pricier, they offer enhanced functionality and convenience.
Carbon monoxide detector cost
Carbon monoxide (CO) detectors are often combined with smoke detectors for comprehensive protection. All-in-one combination smoke and CO detectors cost $40 to $100+ each before installation. Alternatively, you can install a separate CO detector for slightly less. The installation process and cost are about the same for CO detectors as for smoke detectors.
Smoke detector price factors
Several factors can influence the overall cost of smoke alarm installation:
Detector type: Hardwired models typically cost more to install than battery-operated ones due to the need for additional electrical work.
Number of units: Most homes require multiple smoke detectors, which increases the total cost. However, professionals often lower the cost per unit when you're installing several smoke detectors. You can also find discounted bundles of 5+ detectors at major hardware stores like Lowe's or Home Depot.
Accessibility: Installation in hard-to-reach areas or locations requiring special equipment may increase labor costs.
Replacement vs. new installation: If you're replacing hardwired detectors, the presence of existing wiring can reduce installation costs. For new hardwired installations, running electrical wiring costs $0.10 to $4.00 per linear foot before labor.
Local regulations: Some building codes have specific requirements for smoke detector placement and type, potentially affecting costs. For example, some areas require detectors to be on a separate circuit. Installing a new circuit breaker costs about $150 to $300.
Brand & features: Higher-end brands and detectors with advanced features typically cost more.
Warranties: If you have a home warranty, it may cover replacing the smoke detectors. Check your policy terms and conditions to confirm your specific coverage details.
Hardwired smoke detector vs. battery-powered model
Battery-powered smoke detectors are budget-friendly, and many people choose to install them DIY. Hardwired smoke detectors cost more as they typically require the experience and expertise of a licensed electrician. Still, hardwired smoke alarms tend to be more reliable since they offer both electrical power and backup battery power.

Installation Labor
The labor cost to install a smoke detector ranges from $100 to $260+, depending on the complexity of the job and the professional you hire. Hardwired smoke detector installations that involve running new wiring or electrical panel modifications take much longer and cost more than installing simple battery-operated detectors.
Hiring an electrician costs $50 to $130 per hour on average.
Handyperson rates range from $50 to $80 per hour.
Many pros also have a minimum call-out fee for small projects. If you don't have many detectors to install, consider bundling additional services to avoid these extra fees.
Extra features
Modern smoke detectors often come with additional features that increase their cost but also provide enhanced safety and convenience. Common upgraded features include:
Voice alerts
Smart connectivity
Interconnected system
Weather/disaster notifications
Combination smoke and carbon monoxide detection
Flashing lights or other visible notifications (for the hearing impaired)
Security system integration
Many home security systems offer smoke and carbon monoxide detectors as add-on components to create a fully integrated home protection system.
An IQ smoke detector sensor from Brinks Security Systems costs $89.00.
Adding a smoke and CO listener device to a Ring alarm security system costs $34.99 to $39.99.
Battery-powered smoke detectors for an ADT security system cost $39.99 when purchasing a self-setup package. Hardwired smoke and CO detectors cost about the same but require professional ADT installation.
Where to install smoke detectors
Proper placement of smoke detectors is crucial for effective fire protection. For maximum protection, install interconnected smoke detectors so that when one alarm sounds, they all do. The National Fire Protection Association (NFPA) recommends installing smoke detectors:
Inside and outside each bedroom
On every level of the home, including the basement
In the living room or near the stairs leading to an upper level
In the kitchen (at least 10 feet from cooking appliances to minimize false alarms)
For new homes, the International Residential Code (IRC) and NFPA recommend installing a fire sprinkler system as well. Fire sprinkler systems cost $1.50 to $3.00 per square foot to install during new construction. This upgrade can potentially save lives, reduce property loss, and may reduce your homeowners insurance premiums.
Smoke detector FAQs
How many smoke detectors do I need?
The number of smoke detectors you need depends on local building codes and the size and layout of your home. An average two-story, 3-bedroom home typically needs at least 5 smoke detectors. At a minimum, you should have one on each level of the home, one in each bedroom, and one outside each sleeping area.
Do hardwired smoke detectors have batteries?
Yes, most hardwired smoke detectors have backup batteries. These batteries ensure the detector continues to function during power outages. Replace these backup batteries regularly, typically at least once a year, to ensure the alarm functions correctly with or without electricity.
How long do smoke detectors last?
Smoke detectors typically last 8 to 10 years. After this time, the sensing mechanisms can become less effective, even if the alarm still sounds during tests.
The U.S. Fire Administration advises to:
Test smoke alarms every month.
Replace 9-volt smoke alarm batteries at least once a year or sooner if the detector starts beeping or chirping.
Replace smoke alarms 10 years from the manufacture date, if not sooner.
Replace all smoke alarms at the same time.
Do smoke detectors detect carbon monoxide?
Standard smoke detectors do not detect carbon monoxide. However, combination units that detect both smoke and CO are available. If you want protection against both hazards, ensure you purchase a combination detector or install separate CO detectors.
What batteries do smoke detectors use?
