Sewer Line Upgrades for ADU Construction in Encinitas: What Homeowners Need to Know

Cardiff ADU Luke Weinbaum July 2, 2025

This mid-century Cardiff, California (Encinitas, California) beach house featured some lovely original cast iron and clay pipes we could not wait to upgrade. You will also find orangeburg pipe along Neptune Avenue in Encinitas and throughout certain homes in San Diego. Orangeburg pipes were an alternative to metal in 1945-1972 and are made of wood pulp layers and sealed with tar pitch. They can be prone to moisture and deterioration over time. If you are buying a home or planning a construction project involving sewer, you may consider getting a sewer scope camera service on your pipes to see if your pipes should be upgraded. Reach out to us for a sewer scope inspection referral.

Upgrading the utility infrastructure, including sewer pipes was a key part of our successful ADU construction strategy and end product. 

Introducing bobcats and backhoes to the ADU project was a major blessing, especially after seeing a shovel wear out. I didn't know that was possible!
