State guide
Indiana
Indiana has statewide plumbing and sanitary-sewer construction rules, but private lateral ownership is mostly set by the local utility. Current official Indiana sources show mixed local practice: Citizens Energy Group generally makes the owner responsible to the main connection, while Evansville materials place off-property or easement portions with the utility.
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
- Usually local in Indiana: Citizens Energy Group places owner responsibility from the home to the main connection, while Evansville materials say the utility maintains sewer main and off-property or easement portions of the service line.
- State agency
- Indiana Department of Homeland Security; Indiana Department of Environmental Management
- Permits for repair or replacement
- Indiana’s plumbing code is statewide, and Citizens says most lateral alterations or repairs need a sanitary sewer lateral permit before work begins.
- Inspection at sale
- Not published by an official source we could verify. Ask the office.
- Assistance programs
- Current official help found is program-specific rather than statewide: Citizens’ STEP septic-to-sewer projects include a three-year warranty, and Citizens is responsible for items within the right-of-way in those low-pressure systems.

- In Indianapolis or Westfield, have your contractor pull the sanitary sewer lateral permit before any repair, lining, cleanout installation, or replacement work.
- If you are being connected through a STEP project area, ask whether your system is still inside the three-year warranty period.
