State guide
Utah
Utah's statewide plumbing amendments require buildings with plumbing to connect to a public sewer when the sewer is accessible and within 300 feet of the property line. For maintenance responsibility, the official city and district pages I found place the sewer lateral on the property-owner side, with local permitting and inspection rules controlling repair work.
Checked against official sources on October 4, 2026. Rules and links change; confirm with the office listed before you act.
- Who usually owns the sewer lateral
- Utah statewide code does not assign one universal maintenance boundary for municipal laterals in the sources I found; official local pages such as Provo's place maintenance of the sewer lateral on the property owner.
- State agency
- Local public utilities or building department; statewide plumbing amendments are set in Utah Code Title 15A.
- Permits for repair or replacement
- Utah's statewide amendments require sewer connection when accessible within 300 feet of the property line, and the local permit pages found say modifying plumbing requires a permit and that Salt Lake City Public Utilities processes repair permits.

What to do next
- Check both your city utility standards and your building-permit rules before opening a trench, because Utah responsibility and permit handling are local.
- If you are remodeling in Provo, ask whether your existing lateral can be reused; the city standards require size, slope, and condition review.
- In Salt Lake City, confirm whether your work goes through Building Services or Public Utilities Development Services before applying.
