Does Corte Madera Require a Lateral Test?
Yes. If you are selling a house in Corte Madera, California, the private sewer lateral has to be inspected and tested — Sanitary District No. 2's 2018 Private Sewer Lateral Ordinance is triggered by a sale or any other transfer of title. It is not only sales: the same ordinance is triggered by renovations of roughly $50,000 or more over three years, by adding an ADU, by water meter, fire sprinkler or fixture changes, by a sewage overflow or lateral malfunction, by certain road and sewer main projects, and any time the District asks. Avanté Plumbing runs sewer camera inspections and lateral repairs across Marin County under California CSLB licence #841938 (C-36 Plumbing), family-run since 2004. Worth knowing: the ordinance is administered by Sanitary District No. 2, not by the Town on its own and not by Central Marin Sanitation Agency, which is the regional treatment agency.

Local detail
Plumbing in Corte Madera: what's actually different here
Water chemistry, housing age and city rules vary across the North Bay. Everything below is sourced from Corte Madera and Marin County public records.
What triggers a sewer lateral inspection in Corte Madera?
Seven things, not just a sale. Sale or transfer of title; renovations generally totalling $50,000 or more within three years; certain ADU, water meter, fire sprinkler or fixture changes; a request from Sanitary District No. 2; a sewage overflow or lateral malfunction; and specified road or sewer main projects. Because the renovation trigger is cumulative over three years, owners who remodel in stages are caught by it more often than they expect.
Who actually enforces the lateral rule in Corte Madera?
Sanitary District No. 2. This trips people up, because Central Marin Sanitation Agency is the name most Corte Madera residents recognise — but CMSA is the regional wastewater treatment agency, not the body that administers the private lateral ordinance. Compliance paperwork and sign-off go through Sanitary District No. 2, so that is who the inspection has to satisfy.
How hard is Corte Madera's water?
Soft to moderate, depending on the blend. Corte Madera is supplied by Marin Water, whose 2024 Annual Water Quality Report lists total hardness of 58 mg/L (range 49–67) for one reported source and 123 mg/L (range 110–130) for another. Which figure applies depends on the service area and source blend on the day, so the honest answer is that Marin Water is softer than most of Sonoma County but not uniformly soft. Softer water is easier on a water heater than the 109 mg/L supply over in Glen Ellen.

“My septic was over flowing and Karl helped me figure out it was the leach lines that were clogged. He helped me excavate my leach lines and then repaired them quickly so I could use the toilet. He also repaired the baffled T in the septic tank.”
