Hardwired & Battery CA Code Compliant $110-$400/unit Same-Day Service

What's Included in Our Smoke Detector Installation

Home Safety Assessment

We inspect every room to determine proper detector placement per California code -- bedrooms, hallways, each level, kitchen proximity, and garage-adjacent areas.

Hardwired Interconnected Systems

When one alarm sounds, every alarm in the home sounds. Hardwired detectors with battery backup provide the highest level of protection for your family.

Sealed 10-Year Battery Units

California-compliant sealed battery detectors with tamper-proof design. No battery replacement needed for the full 10-year life of the unit.

Carbon Monoxide Detectors

CO detectors installed outside every sleeping area as required by California SB-183 for homes with gas appliances, fireplaces, or attached garages.

Smart Detector Options

Wi-Fi connected detectors that send alerts to your phone, self-test, and provide voice alerts identifying the type and location of the hazard.

Compliance Documentation

We provide a complete compliance report documenting detector locations, types, and installation dates -- essential for home sales, insurance, and rental properties.

Signs You Need New Smoke Detectors

Your smoke detectors are over 10 years old. Smoke detector sensors degrade over time. Units older than 10 years may not detect smoke fast enough to provide adequate warning. Check the manufacture date on the back of each unit.
Your detectors chirp despite new batteries. Persistent chirping after battery replacement indicates the unit has reached end of life. California law now requires sealed 10-year battery units for all new battery-only installations.
You are missing detectors in required locations. California requires detectors in every bedroom, outside each sleeping area, and on every level. Many older homes only have detectors in hallways, missing bedrooms entirely.
You have no carbon monoxide detectors. California requires CO detectors in all homes with gas appliances, fireplaces, or attached garages. CO is odorless and kills over 400 Americans annually.
You are selling your home or renting it out. California requires disclosure and compliance with smoke and CO detector requirements at point of sale. Landlords must install and maintain detectors in all rental units.
Your detectors are not interconnected. In a multi-story home, a fire on the first floor may not be heard by someone sleeping on the second floor if the detectors operate independently. Interconnected systems sound all alarms simultaneously.

Smoke Detector Installation FAQs

How much does it cost to install smoke detectors in Murrieta, CA?

Smoke detector installation in Murrieta costs $110 to $400 per unit installed, depending on the type. Battery-operated sealed-battery units cost $70 to $150 installed. Hardwired interconnected smoke detectors cost $150 to $400 per unit including wiring and labor. A typical 3-bedroom home needs 5 to 7 detectors, bringing the total to $550 to $2,800. Power Man Electric offers free estimates for whole-home smoke detector systems.

What are California's smoke detector requirements in 2026?

California requires smoke detectors in every bedroom, outside each sleeping area, and on every level of the home including the basement. Since July 1, 2014, all battery-only smoke detectors sold and installed in California must have a sealed, non-replaceable 10-year battery (per SB-745). Carbon monoxide detectors are required in all homes with fossil fuel appliances or attached garages (per SB-183). New construction and remodels require hardwired, interconnected smoke detectors.

Should I get hardwired or battery-operated smoke detectors?

Hardwired interconnected smoke detectors are the safest option because when one alarm sounds, all alarms in the home sound simultaneously. This is critical for multi-story homes where a fire on one floor needs to alert people sleeping on another. Hardwired units also have battery backup for power outages. Battery-only detectors with sealed 10-year batteries are acceptable under California law and are the more affordable option for existing homes where running new wiring would be impractical.

Do I need carbon monoxide detectors in my California home?

Yes. California's Carbon Monoxide Poisoning Prevention Act (SB-183) requires CO detectors in all dwelling units with fossil fuel burning appliances, fireplaces, or attached garages. CO detectors must be installed outside each sleeping area on every level of the home. Combination smoke/CO detectors are available and can satisfy both requirements in a single unit.

How often should smoke detectors be replaced?

Smoke detectors should be replaced every 10 years regardless of type, as the sensors degrade over time. CO detectors have a shorter lifespan of 5 to 7 years. Check the manufacture date on the back of each unit. California's sealed 10-year battery detectors are designed to be replaced as a complete unit when the battery expires. Power Man Electric can inspect your existing detectors and replace any that are expired or non-compliant.
