New Home Impact Fee Amendments

HB 570 changes how Utah local governments and private entities calculate impact fees for new single-family homes. It requires using the number of plumbing fixtures (like sinks and toilets) shown in building plans - instead of construction costs or other factors - to determine the fee amount. This directly affects new home builders and local governments that collect these fees for infrastructure projects. The bill amends Utah Code Section 11-36a-305 to standardize this calculation method for single-family residential developments, effective May 2026.
