New Construction Plumbing
Ground-up plumbing installation for commercial buildings, multi-unit developments, and mixed-use projects. Code-compliant systems designed for performance and longevity.
Professional New Construction Plumbing in Orange County
Commercial new construction plumbing requires precision planning, expert execution, and strict code compliance. KCB Plumbing works with general contractors, developers, and project managers across Orange County to deliver plumbing systems for commercial buildings, multi-unit developments, retail spaces, restaurants, and mixed-use projects.
Unlike residential plumbing, commercial systems must handle higher usage demands, meet stricter code requirements, and integrate with fire suppression, grease management, and specialized equipment. Our team has the experience and licensing to handle these complexities, delivering systems that perform reliably under heavy commercial use.
We're involved from pre-construction through final inspection, working within your project timeline and coordinating with other trades. Our experience with Orange County building departments means we know the local code amendments, inspection processes, and permit requirements that keep your project on schedule.

Common Questions
New Construction Plumbing FAQ
What types of commercial buildings do you plumb?
We work on retail spaces, restaurants, offices, medical and dental offices, multi-unit residential, mixed-use developments, warehouses with restroom facilities, churches, and schools. Our license covers both residential and commercial plumbing.
Do you handle grease trap installation for restaurants?
Yes, restaurant plumbing is one of our specialties. We install grease interceptors sized for your operation, connect commercial dishwashers and prep sinks, and ensure compliance with Orange County grease management requirements.
Can you work with our general contractor's schedule?
Absolutely. We're experienced at coordinating with GCs and understand that staying on schedule is critical for commercial projects. We provide detailed scheduling for each phase and have the crew capacity to meet tight timelines.
What sets commercial plumbing apart from residential?
Commercial plumbing involves larger pipe sizes, higher flow demands, commercial-grade fixtures, backflow prevention, ADA compliance, and more stringent code requirements. It also requires closer coordination with other trades and more complex permit processes.
