Detector Installation & Replacement Services

Alta Property Services installs, replaces, and tests smoke detectors and carbon monoxide detectors in homes, rental units, and commercial buildings across the Chicagoland area.

Smoke Detector Installation

New installation of ionization or photoelectric smoke detectors in every required location per Illinois residential code — bedrooms, hallways, and each floor level.

Carbon Monoxide Detector Installation

CO detectors installed near sleeping areas and fuel-burning appliances (furnace, water heater, attached garage) per Illinois Carbon Monoxide Alarm Detector Act requirements.

Combination Smoke / CO Units

Single-unit combination detectors that monitor both smoke and carbon monoxide — ideal for minimizing device count while maintaining full protection in each zone.

Hardwired & Interconnected Systems

Hardwired detector systems with battery backup, fully interconnected so when one alarm triggers, all units in the home sound — required in new construction and major renovations.

Detector Replacement & Upgrade

Smoke and CO detectors expire after 7–10 years. We remove outdated units and install new code-compliant replacements — including upgrading battery-only units to hardwired where required.

Rental Property & HOA Compliance

Detector inspection and installation packages for landlords, property managers, and HOA communities — with written confirmation of code compliance for your records.

Illinois Code Requirements

What Illinois Law Requires for Your Property

Illinois law mandates specific detector placement in all residential properties. Alta installs to meet or exceed these requirements.

1

Detector Per Floor Level

Illinois requires at minimum one smoke detector on every level of the home, including the basement.

10 ft

From Every Sleeping Area

Smoke detectors must be installed within 10 feet of every bedroom door per NFPA 72 and Illinois residential code.

CO

Near Fuel-Burning Appliances

Carbon monoxide detectors are required within 15 feet of sleeping rooms if any fuel-burning appliance or attached garage is present.

10 yr

Maximum Detector Lifespan

Smoke detectors must be replaced after 10 years (manufacturer date on back of unit). CO sensors expire at 5–7 years.

Why Choose Alta

Properly Installed Detectors — Not Just Plugged In

There's a difference between putting a detector on a shelf and a code-compliant, tested installation. Our licensed electricians ensure every unit is correctly positioned, powered, and verified before we leave.

  • Licensed Electricians — Not Handymen

    Hardwired detector systems must be installed by a licensed electrician under Illinois law. Our team carries the proper licensing and insurance.

  • Full Property Assessment

    We walk the entire property and identify every location requiring coverage — not just the obvious spots. You get a compliant layout, not guesswork.

  • Same-Week Scheduling Available

    Real estate closings, rental inspections, and HOA compliance deadlines don't wait. We offer prompt scheduling throughout DuPage, Cook, and Will counties.

  • Documentation for Property Records

Our Process

How the Installation Works

A straightforward process from your first call to a fully verified, code-compliant detector system.

Schedule & Quote

Call or submit the form. We'll confirm the scope — property type, number of floors, existing detectors — and provide an upfront quote with no hidden fees.

On-Site Assessment

Our electrician walks the property, identifies all required detector locations per Illinois code, and notes any hardwiring access points or panel considerations.

Installation

Detectors are installed, wired (where applicable), and interconnected. All work is clean, tidy, and performed with minimal disruption to your property.

Test & Verify

Every detector is tested before we leave. Interconnected systems are verified to confirm all units respond when one alarm triggers. You receive written confirmation.

What Chicagoland Homeowners Say About Alta

Frequently Asked Questions

Smoke & CO Detector Questions

How many smoke detectors does my home need in Illinois?
Illinois law requires at least one smoke detector on every level of the home, including the basement, and within 10 feet of every sleeping area. Many homes require 4–8 units depending on layout. Our electrician will assess your specific floor plan and provide a compliant placement plan.
Do I need carbon monoxide detectors if I have an all-electric home?
If your home has no fuel-burning appliances (no gas furnace, gas stove, gas water heater) and no attached garage, Illinois law may not require CO detectors. However, we strongly recommend them if you have an attached garage, as vehicle exhaust can be a source of carbon monoxide exposure. Our team can advise based on your specific setup.
When do smoke detectors need to be replaced?
Smoke detectors have a 10-year lifespan from the manufacture date printed on the back of the unit. Carbon monoxide sensors typically expire after 5–7 years. If your detectors are chirping despite fresh batteries, or if the manufacture date has passed, it's time for replacement. Alta can assess and replace all expired units in a single visit.
What's the difference between hardwired and battery-only detectors?
Battery-only detectors are self-contained and operate independently of your home's electrical system. Hardwired detectors connect to your home's wiring and include a battery backup. Hardwired, interconnected systems are required in new construction in Illinois and are strongly recommended for all homes — when one alarm sounds, all units in the home sound simultaneously. Alta installs both types, and can upgrade battery units to hardwired where code requires it.
Do you serve rental properties and multi-unit buildings?
Yes. We work with landlords, property managers, and HOA communities across Chicagoland. We can install detectors in multiple units, provide documentation for your lease records, and schedule at times that minimize disruption to tenants. Call us to discuss volume pricing for multi-unit properties.
How long does a smoke and CO detector installation take?
A standard single-family home installation (battery or plug-in units) typically takes 1–2 hours. Hardwired installations that require running wire or accessing the electrical panel take longer depending on the home's layout. We'll give you an accurate time estimate when you schedule.
What areas does Alta serve for detector installation?
Alta Property Services is based in Addison, IL and serves communities throughout DuPage, Cook, Will, and Lake counties — including Arlington Heights, Naperville, Schaumburg, Bolingbrook, Evanston, Palatine, Glenview, Northbrook, and many more. Contact us to confirm coverage in your area.
