A sewer system has two parts that matter here: the public main, usually under the street, and the private lateral that connects each building to it. Cities generally maintain the main. Responsibility for the lateral, including the stretch under the parkway, sidewalk or street, depends on local rules.

In many Orange County cities the property owner is responsible for the lateral all the way to the main. That can surprise owners when a break turns out to be near the curb. Rather than assume, ask the City of Placentia where your responsibility ends before you approve work or pay for anything beyond your property line.

Questions to ask the city

  1. Where does owner responsibility for the sewer lateral end at my address?
  2. What permits are needed for repair or replacement on private property?
  3. What permits or approvals are needed for work in the parkway, sidewalk or street?
  4. Is a city inspection required before the trench is backfilled?
  5. Who do I contact if I suspect a blockage in the public main?

Paperwork to keep after a repair

  • The written estimate and final invoice describing the work

  • The before and after camera footage
  • The contractor's name and CSLB license number, checked at cslb.ca.gov
  • Notes on pipe material, length replaced and where the work was done

An illustrative example

Illustrative example. Not a real job or customer.

A camera shows the lateral is broken under the sidewalk near the curb, and the homeowner is unsure whether it is their pipe or the city's.

  1. The homeowner keeps the footage and the distance to the break.
  2. They contact the City of Placentia to ask where owner responsibility ends at their address.
  3. Once confirmed, they ask the contractor to include the needed permits and any street or sidewalk work in the written scope.

The owner knows who is responsible before work starts and the permit question is settled in writing.

Common questions

If the problem is in the public main, do I pay for it?

Generally, public main issues are handled by the city or its sewer agency. Report suspected main problems to the city and ask what happens next.

Can I do my own sewer lateral repair?

Rules vary for owner work and permits. Check with the city first, and remember that excavation near utilities carries real risk.

Does the contractor need a license?

In California, contractors generally need a CSLB license for this kind of work. Ask for the number and look it up at cslb.ca.gov.
