Plumbing Company Los Angeles CA | Call Ketterling Construction

Adding an ADU in LA involves specific zoning rules, setback requirements, and utility connections. With 30 years of local experience, Ketterling Construction manages the entire process—from design and securing permits to construction that meets city code—ensuring your new structure is both a valuable investment and a compliant, functional space.

Yes, absolutely. We start with a thorough plumbing inspection to diagnose issues common in LA, like mineral buildup from hard water or older pipe systems.

A major addition requires careful structural planning, design integration with your existing home, and adherence to strict Los Angeles building regulations. We handle everything: engineering assessments, permit acquisition, and seamless construction, ensuring the new space feels like a natural part of your home while enhancing its functionality and value.
