Fire Sprinkler System Cost Factors
When installing a home fire sprinkler system, you’ll consider factors like the size of your home and the system you install. You should weigh these lifetime costs against the ongoing protection unlocked by installing a fire sprinkler system.
Square Footage
You’ll pay more to install a home sprinkler system if you have a larger home because you’ll need more materials, and the installer will spend more time setting them up.
New Home vs. Add-On
It’s more difficult to retroactively add a home sprinkler system than it is to add one during the construction of a new home. With that in mind, new home sprinkler systems cost less per square foot than those in existing homes.
For new construction, you’ll pay between $0.50 and $3 per square foot for residential fire sprinkler system costs, whereas prices start at $2 and may go up to $7 per square foot for existing residences. Installing sprinkler systems in high rises will end up costing around $4 per square foot.
| Type of Home | Average Cost (Per Square Foot) |
|---|---|
| New home | $0.50–$3 |
| Existing home | $2–$7 |
| High-rise building | $4 |
Pipe Material
Installers use three main types of sprinkler pipes: nonmetallic, copper, and a mix of metallic and nonmetallic materials. Nonmetallic options include CPVC (chlorinated polyvinyl chloride) and PEX (cross-linked polyethylene). Your fire sprinkler company can help you choose the best pipe material for your system.
| Pipe Material | Average Cost (Per Square Foot) |
|---|---|
| CPVC or PEX | $1–$2 |
| Mixture | $1–$2 |
| Copper | $3–$4 |
Smoke Detectors
According to the National Fire Protection Association (NFPA), a working smoke alarm more than doubles your chance of surviving a house fire. Check the batteries every three months and replace your smoke detector every 10 years. New batteries cost about $10 to $25, and replacement smoke detectors run from $15 to $65 on average.
Carbon Monoxide Alarms
Carbon monoxide can cause illness or even death in high doses. However, it's invisible, odorless, and colorless, so you need a detector to know it’s there. Newer models will last up to seven years and range from $15 to $150 on average.
Heat Sensors
Heat sensors detect significant temperature spikes in addition to smoke. The sensors run anywhere from $60 to $100 per sensor.
Chimney Cap Spark Arrestor
This essential part of the chimney cap keeps sparks and flying embers from landing on your roof or its surrounding area, preventing fire hazards. The metal meshing also helps keep small critters from crawling into your chimney. A chimney cap costs about $300 to install.
Permits and Inspections
Home sprinkler system installers must have permits and have their work inspected before the job is done. Permitting and inspections cost extra, and installers pass those fees along to their clients. Expect the total cost to range between $50 and $350. However, your cost may be significantly higher, depending on where you live. Your local building department can give you an estimate for your home.
Water Source
If your home is connected to a public water utility, you won’t need to include this fee. But if you use well water or another source, your residential fire sprinkler system will likely need a booster pump and tank so it has the water it needs to function. This is a large expense in most cases and can add 20% to 25% of the system's cost to your overall budget.
Backflow Preventers
Backflow preventers keep fire sprinkler water from flowing back into the municipal water supply. While not every location requires backflow preventers, it’s a smart idea to include them in your system, especially if doing so keeps antifreeze or other chemicals out of the water. To add a backflow preventer to your home sprinkler system, plan for a cost of $75 to $350.
Additional Costs to Consider
If you’re focused on fire safety, there are a few additional costs to consider to increase your preparedness level in the event of a fire.
| Additional Items | Average Cost |
|---|---|
| Fire extinguishers | $100–$500 |
| Fire blankets | $10–$100 |
| Private fire hydrants | $3,000–$7,000 |
Maintenance Costs
Most residential fire sprinklers don’t need much maintenance, but you’ll want to have a professional inspect yours every year. This costs an average of $300 to $500, and any repairs or replacement parts will add to the estimate.
Fire Extinguishers
New fire extinguishers cost between $100 and $500 and are available at most home improvement stores. The NFPA recommends inspecting and maintaining your fire extinguisher annually, which costs an additional $30 to $100 per year. The best location for an extinguisher is in an accessible and visible area for quick and easy access. Make sure you have the right kind of fire extinguisher for your needs.
Fire Blankets
Fire blankets cost $10 to $100 on average. Most non-flammable blankets are designed for up to 900 degrees and can put out small fires with ease. One blanket will last around seven years.
Private Fire Hydrants
Private fire hydrants cost between $3,000 and $9,100 and are built on someone’s personal property. The price varies based on the hydrant’s classification, which depends on how many gallons per minute it can handle.

Cost to Install a Fire Sprinkler System Yourself vs. Hiring a Pro
Installing a home fire sprinkler system is not a good DIY project because it involves intricate wiring and piping. You also need contracting, plumbing, and electrical experience for this job. If you don’t have that experience and try to DIY this project, it could lead to flooding and water damage. A local fire sprinkler company will help ensure your indoor fire system works when needed.
Ways to Reduce Residential Fire Sprinkler System Costs
While there may not be a way to reduce the up-front cost of a fire sprinkler system other than getting quotes from multiple companies, other financial incentives may help offset the cost. When pricing out the project, contact your insurance company to see if they can reduce the premiums for a home with a fire sprinkler system. You can also contact your local government to see if they offer incentives or funding for fire sprinkler system installation.

Frequently Asked Questions
A home fire sprinkler system reduces heat, flames, and smoke within seconds. Fire sprinkler systems hide in walls with sprinkler heads running along the piping throughout your home.
When the air surrounding a sprinkler reaches a specific temperature, the heads closest to the fire activate and release anywhere from 10 to 25 gallons of water per minute.
The NFPA model codes and International Residential Code (IRC) mandate that all new one- and two-family homes have fire sprinkler systems. However, all municipalities are different. The best way to determine if your municipality requires fire sprinklers is to contact your state fire marshal’s office. One reason to install a fire sprinkler system is that it’s the first line of defense in putting out a fire and alerting your family of emergencies.
Residential fire sprinkler systems have a couple of drawbacks, including the cost to install, particularly for high-rise buildings or existing buildings, and the potential for water damage if the sprinklers go off. You will also need to keep up with annual inspections to make sure the system will work as intended during an emergency.
But keep in mind that sprinklers can save lives, and the cost to repair water damage (about $400 to $4,700) is less than the average cost of fire damage restoration (about $3,200 to $51,600).
While adding fire sprinklers to your home, you may want to consider other fire prevention and protective measures. Get your smoke alarms and CO alarms inspected and replaced, if needed. Add fire doors to vulnerable areas of your home. Inspect or purchase fire extinguishers. For exterior protection, consider fire-smart landscaping practices.
Fire sprinkler systems give your home’s value a boost. Potential home buyers are looking for a safe place to settle, and a well-maintained sprinkler system can provide peace of mind. Plus, some homeowners insurance policies offer discounted rates for homes with this type of built-in system, thanks to the decreased risk of fire.
