A national poll conducted by Harris Interactive® found that nearly two-thirds (69 percent) of U.S. homeowners say having a fire sprinkler system increases a home’s value.

• 38% of homeowners say they would be more likely to purchase a new home with sprinklers than without them.
• 45% say a sprinklered home is more desirable than an unsprinklered home, most often because of added safety provided by sprinklers (51%).
• 63% of homeowners are aware fire sprinklers are available for home use.

Homebuilders who offer fire sprinklers are seen by homeowners as being “safety concerned” (70%), “innovative” (52%) and “caring” (51%).
