Sewer lateral repair in Los Angeles and the LASAN rebate
Updated · Editorial team; not yet technically reviewed
Short answer
In Los Angeles, the property owner is responsible for maintaining and repairing the whole sewer lateral, both the upper lateral to the property line and the lower lateral out to the main in the street or alley. LA Sanitation (LASAN) offers a rebate of up to $2,500 toward lateral repairs, first come, first served, and it requires the city inspector's signed final permit.
What's different in Los Angeles
A sewer lateral carries wastewater from a building to the mainline sewer; the upper lateral runs from the building to the property line and the lower lateral from the property line to the main, usually in the street, alley or an easement. [1]
Property owners are responsible for maintaining and repairing their sewer lateral. [1]
LASAN's sewer lateral rebate reimburses up to $2,500 to qualifying property owners who pay the sewer service charge, first come, first served until the year's funds run out. [1]
A copy of the final permit signed by a City of Los Angeles inspector is required to apply for the rebate. [1]
Upper lateral, lower lateral
The lower lateral is the part owners forget: it runs under the sidewalk and street to the main, and in Los Angeles it's still yours. Repairs there involve street work, traffic control and city permits, which is why lower-lateral jobs cost far more than a yard repair. A camera inspection tells you which side of the property line the problem is on before you get quotes.
