How cheap do sprinklers have to be before they’re considered cost-effective?

Money house (2).pngThe cost of residential fire sprinkler systems has been a major point raised by builders in the residential fire sprinkler battle. They often cite unknown studies pointing to how many people will not be able to afford a home if the residential (one and two-family) code requirement is adopted.

Some time ago I sat next to an actuary during one of my many flights and engaged in conversation as I often do with my seat mates. Of course, the conversation turned to residential fire sprinklers. He had not even thought of this technology when making a home purchase decision.

The very first question he asked was, you guessed it; how much does it cost? A recent study revealed the average cost is $1.35 a square sprinklered foot. Immediately his mathematical mind went to work and within seconds he said; "That would only translate into approximately $5.00 extra mortgage payment a month."

During one of the hearings I attended someone provided testimony begging the question posed by the title of this blog. I bring it to you here in its entirety and urge you to make similar analogies - if given the chance - when addressing the cost of residential sprinkler systems.

The testimony follows:

"To really look at the issue of the cost impact on homes and whether sprinklers will impact the cost of affordable housing, there is a basic question that has to be asked; What drives the price of a new home? In many, if not most, markets, the answer to this question is not construction costs, but instead, what the market will bear, with sales prices rising and falling based on what buyers are willing to pay. In such markets, costs associated with mandatory sprinklers are absorbed into the price by adjusting other costs or features or builder markup.

Even if there is an increase in the cost of a home based on sprinklers, the impact on a monthly mortgage payment is negligible in an average home.

Consider a hypothetical $3,000 sprinkler system in a $300,000 home with a 6.5% mortgage, a 5% credit on a $2,000/year insurance bill, and a combined Federal/State income tax rate of 33%; the net cost of fire sprinklers, after mortgage related tax deductions, would be $4.37 per month. This represents a 0.23% increase in the monthly payment and roughly equates to the cost of a premium beverage at your local coffee shop”

So, I pose the question to everyone today: just how cheap do sprinklers have to become before they’re considered cost-effective?
