The 2009 International Residential Code called for mandatory fire sprinklers in all new single-family residences, and since then firefighters have been advocating for local codes to follow suit.
Homebuilders, however, have resisted this effort. The latest flare-up over this issue is in Tennessee, where the state Senate earlier this month voted to repeal all local government ordinances that require sprinkler systems in townhomes attached to two or more other townhomes. Builders say adding sprinklers raises the price of a home by $5,000 to $15,000.
