New Construction Plumbing Services

Underground Rough-In

Trenching, underground drain, waste, and vent (DWV) pipe installation, and water supply rough-in before the slab is poured.

In-wall and in-ceiling DWV and supply rough-in after framing — sized and routed to pass city inspection before drywall.

ADU & Room Additions

Full plumbing rough-in for accessory dwelling units and additions, including tie-ins to existing supply and sewer lines.

Trim-Out & Fixture Setting

Final connection of all fixtures — toilets, sinks, tubs, showers, dishwashers, water heaters, and hose bibs — after drywall and tile.

Commercial New Construction

Multi-unit residential, light commercial, and mixed-use new construction plumbing — coordinated with GC schedules and permit timelines.

How New Construction Plumbing Works

1

Plan Review & Permit Pull

We review your architectural and structural plans, submit plumbing drawings to the city, and pull all required permits before breaking ground.

2

Underground & Slab Rough-In

All underground DWV and water supply lines are installed, inspected, and pressure-tested before the concrete slab is poured.

3

Top-Out Rough-In

After framing, we install all in-wall and in-ceiling supply and drain lines, vent through the roof, and schedule the rough-in inspection.

4

Rough-In Inspection

We coordinate directly with the city inspector. Our work passes the first time — no delays to your GC's drywall schedule.

5

Trim-Out & Fixture Setting

After drywall and tile, we return to set all fixtures, connect appliances, and complete the final plumbing installation.

6

Final Inspection & Sign-Off

We schedule and pass the final plumbing inspection, providing all documentation needed for your certificate of occupancy.

Yes. A-Team Plumbing handles all permit applications and coordinates inspections with the City of Los Angeles, LA County, and surrounding municipalities including Burbank, Glendale, and Santa Clarita. We submit plumbing drawings and pull all required permits before work begins.
What is rough-in plumbing?
Rough-in plumbing refers to the installation of all supply, drain, waste, and vent (DWV) pipes inside walls, floors, and ceilings before drywall and finishes are applied. It includes underground slab work, in-wall supply lines, and vent stacks. Rough-in must pass a city inspection before drywall can be installed.
Can you handle plumbing for an ADU or room addition?
Absolutely. We specialize in ADU and room addition plumbing throughout Los Angeles. This includes tying into the existing sewer and water supply, running new supply and DWV lines, and completing all rough-in and trim-out work to pass city inspection.
How long does new construction plumbing take?
Timeline depends on project size. A typical single-family home rough-in takes 3–5 days. ADUs and additions typically take 1–3 days for rough-in. We coordinate with your GC to fit within the project schedule and minimize delays.
Do you work on commercial new construction?
Yes. We handle light commercial and multi-unit residential new construction plumbing, including apartment buildings, mixed-use projects, and retail build-outs. Contact us with your plans for a project estimate.

"Robert did an excellent job communicating throughout the scheduling process and kept us informed every step of the way. Victor arrived right on time, was extremely professional, and communicated clearly throughout the visit. Based on our experience, this company will very likely become our go-to vendor moving forward. Highly recommended!"

"10/10 Highly recommend these guys! They responded quickly to my inquiry that I sent after-hours, and gave me a flat fee quote right then and there. I was able to have a plumber scheduled first thing in the morning and he arrived on time — he was quick, very clean, communicative, and so kind. Thank you A-Team!!"

"A Team Plumbing was recommended to me by a trusted friend and I will heartily recommend them as well. Guilo really knows his stuff. Being able to trust expertise and having the job done right is always more important to me than the lowest price. I'm very happy with my new faucet and will gladly hire A Team again."
