Professional Tenant Improvements in Orange County
Tenant improvement (TI) plumbing is all about transforming an existing commercial space to meet the new tenant's needs — whether that's adding restrooms to an office suite, plumbing a commercial kitchen for a restaurant, or reconfiguring a retail space. KCB Plumbing handles TI plumbing throughout Orange County, with the scope confirmed against the plans and the project schedule. For a Santa Ana beverage shop, KCB installed new underground drain piping and water connections for the sinks and beverage equipment.
Every TI project is different. A restaurant build-out may involve floor drains, grease-control requirements set by the sewer agency, and water heating for the kitchen. An office suite may need restroom additions or break room plumbing. Each scope is confirmed against the plans and field conditions.
Share the schedule, phases, and any occupied-space constraints early so the plumbing work can be planned around the other trades.

Common Questions
Tenant Improvements FAQ
How long does plumbing for a tenant improvement take?
It depends on the scope, the plans, inspections, and coordination with other trades. KCB provides a schedule for its phases during estimating.
Can you work around an operating business?
Often, depending on the scope. Shutoffs, work hours, access, and how other tenants are affected are planned with the property team before work begins.
Do TI plumbing projects require separate permits?
Most tenant improvement plumbing work needs a plumbing permit from the local building department. Who pulls the permit and schedules inspections is confirmed in the scope.
What if the existing plumbing infrastructure is insufficient?
We assess the existing main line sizes, water supply capacity, and sewer connections during our initial survey. If upgrades are needed, we include them in our scope and coordinate with the building owner and municipality.
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.”
