Professional New Construction Plumbing in Orange County
Commercial new construction plumbing requires careful planning and coordination with the plans, permits, and inspections. 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.
Commercial systems may need to handle higher usage, meet requirements that differ from residential work, and coordinate with grease management and specialized equipment, depending on the building. KCB is licensed, insured, and bonded (Lic #604044) and confirms the plumbing scope against the plans before work begins.
Permit and inspection requirements vary by city, so we confirm what applies when we define the scope, and we coordinate our phases with the general contractor's schedule and the other trades.

Common Questions
New Construction Plumbing FAQ
What types of commercial buildings do you plumb?
We work with contractors, property managers, and HOAs on retail spaces, restaurants, offices, multi-unit residential, and mixed-use projects. Call with the project details so KCB can confirm the scope.
Do you handle grease interceptors for restaurants?
Interceptor requirements are set by the sewer agency serving the address under the facility's permit. Call with the plans and the agency's requirements so KCB can confirm whether the installation is within its scope. KCB does not pump interceptors; a permitted grease hauler handles that.
Can you work with our general contractor's schedule?
Yes. Share the schedule, phases, and access constraints during estimating so KCB can confirm what is practical for each phase.
What sets commercial plumbing apart from residential?
Commercial work often involves larger pipe sizes, higher flow demands, commercial-grade fixtures, backflow prevention, and accessibility requirements, depending on the building. It usually needs closer coordination with other trades and the permit process.
Customer Reviews
What Customers Say
“The owner Kevin Blue has done plumbing work for me before. He is very helpful and knowledgeable. He always arrives as promised and the work is always satisfactorily completed.”
“Keevin was extremely personable, patient (big plus!), and knowledgeable. He explained the issues that we had in our new home and answered all of our questions, and most importantly, understood that we were on a budget considering there were so many things that we needed to take care of. My husband is probably one of the most suspicious persons on earth but even he found Keevin to be very trustworthy and straightforward with his suggestions and advice.”
