Who pays for the sewer lateral in Riverside, CA

Who is responsible for which part

Riverside is the one city here that divides the lateral by the kind of building rather than by where the pipe runs. For a house, the City maintains the run from the property line to the main. For "nonresidential premises" - which its code defines to include apartments, condominiums and boarding houses - the owner's pipe runs all the way to the connection. Everyone must install and pay for a cleanout at the property line.

Riverside

The lower lateral of a house, and only of a house. Section 14.08.020.B states that "the City shall maintain the sewer lateral of residential premises (excluding nonresidential premises) beginning at the property line or City easement boundary to the point of connection to the City sewerage system". The code's definitions put apartments, condominiums and boarding houses outside that, so the City takes no part of their laterals.

The property owner

Everything up to where the City's duty begins, and for some homes that is everything. A "private residential sewer lateral line" is defined as running from the premises "to the premises property line or City easement", so a house owner keeps the pipe to the property line. A "nonresidential private sewer lateral line" runs from the premises "to the point of connection to the City sewerage system", so an apartment, condominium or boarding house keeps the whole run including the part under the road. Every customer must also keep the line "in good working order and free of defects (which includes the installation of a two-way clean out tee at the property line or City easement boundary of at least four inches in diameter for maintenance) at their own expense".

What decides which applies

Find out which class your home is in before anything else, because it decides who pays for the run under the road, and the answer is not what the words suggest. The City maintains that length for "residential premises" - but its own definitions make apartments, condominiums and boarding houses NONRESIDENTIAL, alongside industrial and commercial premises. So a house gets the City's half and a condominium does not, even though both are somebody's home and both owners own their property. If you are in a condominium here, your lateral runs to the main and it is yours. Separately, and whichever class you are in, the two-way cleanout tee at the property line is your obligation to install at your own expense, at least four inches in diameter - it is not a condition on the City's duty, it is a duty of your own.

What is required

• When you askWork required

  Riverside requires all customers to keep the private sewer lateral "in good working order and free of defects", which the code says "includes the installation of a two-way clean out tee at the property line or City easement boundary of at least four inches in diameter", at the owner's own expense, with the owner "liable for damages which may result from failure to do so". Root infiltration is "presumed to be caused by improper installation and/or maintenance and shall be repaired by the property owner at no cost to the City, unless determined otherwise by a City inspector and/or City contractor". A City inspector or contractor may be admitted at all reasonable hours to check the lateral "either visually, by camera, or any other means".

  What to do: Check you have a two-way cleanout tee at the property line of at least four inches; if not, installing one is your obligation and your cost, and its absence is the kind of defect the section makes you liable for. If roots are found, ask the City inspector or contractor to record the condition of the pipe at the same time - their determination is the only thing that displaces the presumption that the roots are your fault. And establish whether your home counts as "residential premises" under this chapter, because apartments, condominiums and boarding houses do not, and that decides whether these duties cover the run under the road as well.

  Why this matters▸▾

  The presumption is the part that costs money, and nothing else on this site has one. Root intrusion is the commonest cause of a blocked lateral, and the usual dispute is whose tree and whose pipe. Riverside decides it in advance: roots are treated as evidence that the owner installed or maintained the pipe badly, and only a City inspector or City contractor can displace that. So a homeowner arguing that a street tree caused the damage starts from behind. The cleanout is an obligation rather than a condition here - in several other cities a cleanout decides whether the authority helps at all, whereas Riverside helps houses regardless and still requires you to install one, two-way and at least four inches.
