How the sewer lateral process works
A sewer lateral is the private pipe that carries wastewater from the house to the public sewer main. Many California cities and sanitary districts make sellers prove it does not leak before title can transfer.
- Check whether a valid certificate is already on file for the address. If it is, you may be done.
- Hire a licensed plumber or sewer contractor to video (CCTV) the lateral and, where required, run an air or water pressure test.
- If the lateral fails, the contractor pulls a permit and repairs or replaces it. Many agencies send their own inspector to witness the final test.
- The city or district issues the compliance certificate, and escrow can close.
- If you run out of time, ask about a time extension. These usually require a refundable deposit and a firm deadline after closing.
| Item | Typical range |
|---|---|
| Video inspection or pressure test | $250 to $750 |
| Spot repair | $1,500 to $10,000 |
| Full lateral replacement | $8,000 to $25,000 or more |
