New Construction & Remodeling in the South Bay
Send plans or a room list — underground through fixture set — and we’ll follow up about an estimate.
New construction and remodeling plumbing is sequenced: underground, rough-in, and finish. Skipping that order is how showers end up without blocking, or an ADU shares a sewer tap that cannot handle the extra bathrooms. Schulze Plumbing Inc. builds complete plumbing systems and the remodel pieces of kitchens, baths, and additions in the South Bay.
ADUs behind existing houses are common from Torrance through the beach cities. They need water service, sewer connection, gas when specified, and fixtures that match the plans — not a garden hose tee off the laundry. Multi-unit residential and commercial build-outs add stack coordination and inspection phasing.
Use residential plumbing if you need a single fixture repaired in an occupied house. Use this category when walls are (or will be) open, a GC is running a schedule, or you are building new. Gas, water service, and sewer connections are listed here and also live in their specialty categories.
Who this is for
- Homeowners and GCs building new or opening walls for a remodel
- ADU projects that need a complete plumbing system
- Multi-unit residential rough and finish
- Commercial build-outs that follow construction phasing
Common symptoms
- Plans that show new baths, a kitchen, or an ADU with no plumber engaged yet
- An inspection that failed on rough plumbing
- A remodel that bought fixtures before anyone checked supply and drain locations
- A build-out that needs underground before the slab is poured
What this work involves
- Reviewing layout, fixture counts, and utility connections
- Underground, rough, and finish as separate phases when the schedule requires it
- Installing fixtures at finish, including trims and trim-out
- Coordinating gas, water service, and sewer with the rest of the job

Process
- Share whether this is new construction, ADU, or remodel, and if plans or a fixture schedule exist, plus your ZIP code so we can confirm South Bay coverage.
- We follow up to confirm access, scope, and whether permits or other trades may be involved.
- You receive an estimate for the work you approve. We do not publish prices on this page.
- After you approve, we schedule the job.
FAQ
- Can you plumb from underground through fixture installation?
- Yes. Complete systems are listed as their own service. Phased jobs can also be estimated per stage.
- Do you plumb ADUs?
- Yes. ADU plumbing usually needs its own water, drain/sewer, and often gas or tankless planning. Share the ADU plans, not only the primary house layout.
- What if I only need finish plumbing?
- Finish plumbing is listed separately. We still need to know whether the rough was ours or another contractor’s before we set fixtures.
