Since 1999, Pennsylvania's construction code has been automatically updated to include modifications by the International Code Council, which develops standards for building safety.
The Senate amendment would require the state Uniform Construction Code Advisory Council within the Department of Labor and Industry to choose to adopt code changes.
The sprinkler requirement, which took effect Jan. 1, came about because the advisory council took no action.
Advocates for the sprinkler requirement say that it would save the lives not only of homeowners, but also of firefighters.
The House bill was introduced in January by Rep. Garth Everett (R., Lycoming), who said that the cost of new sprinkler systems ranged from $5,000 to $20,000 in his district.
"When you live out here where I am, in rural Pennsylvania, when you're on a well [water] system, it becomes much more expensive," Everett said in a phone interview.
"I introduced this legislation on behalf of my rural constituents, not the Pennsylvania Builders Association or the Realtors or anyone else," Everett said.
He said that adding a sprinkler system should be optional for a new home buyer, and not a government mandate.
He noted that the repeal would only apply to single-family homes and duplexes, not to apartments, townhouses, or dormitories.
