Representative Ward introduced HB 175, Housing Construction Amendments, saying the bill would let quadplexes and similar small multi‑unit buildings that meet residential fire‑safety features be treated as residential structures rather than commercial for building‑code classification. That change removes the automatic requirement to install sprinklers — typically required under the commercial code — where the residential firewall approach (sheetrock firewall) is sufficient.

Ward said the commercial code's sprinkler requirement adds roughly $4,000 to the cost of each unit in affected buildings. "For future individual homebuyers who bought a condo in a quadplex like this, that would save them about 1% on the cost of their new home," Ward said. Supporters including Representative Peterson praised the sponsor for working with interested parties and said restoring this allowance could help affordable housing production.

No floor amendments were recorded. Voting was opened and HB 175 passed the House 71 yes, 1 no and will be sent to the Senate for its consideration.
