New Construction, ADUs, and Commercial Plumbing Services
Plumbing a New Building? Get It Right Before the Walls Go Up
5 Star Plumbing, Heating, and Air provides professional new construction plumbing for residential and commercial projects. With more than 25 years of plumbing experience, we understand what it takes to move a project from underground plumbing and rough-in to fixtures, connections, testing, and the final stages of the job.
Whether you are building a custom home, adding an ADU, developing a commercial space, or starting another ground-up project, we can handle the plumbing that makes the finished building actually work.
New Construction Plumbing is More Than Installing Pipes
A new plumbing system needs to deliver enough water to every fixture while safely carrying wastewater away from the building. Hot water needs to reach the places it is needed. Drain and vent systems need to function together. Shutoff valves need to be accessible. Fixtures need to land where the plans say they should.
A mistake early in construction can become a much bigger headache later. Move a drain a few inches after the concrete has been poured, and it is no longer a small adjustment. That is why experienced new construction plumbers are important from the beginning of the project.

Residential New Construction Plumbing
We provide plumbing installation for new homes and can work with the project plans to build the water, drain, waste, vent, gas, and fixture systems the home requires.
Custom Home Plumbing
Custom homes usually involve more plumbing decisions than a standard floor plan. Bathrooms may be larger. Kitchens may have multiple sinks or appliances requiring water connections. There may be wet bars, prep sinks, outdoor kitchens, multiple water heaters, oversized showers, or specialty fixtures.
That is where planning matters. We work through the home’s plumbing requirements so the system supports how the property is being built. Because the worst time to discover that a water line, drain, or gas connection should have gone somewhere else is after the walls and countertops are finished.
Plumbing for ADUs and New Living Spaces
Accessory dwelling units have become an increasingly practical way to add usable living space to a property. But an ADU with a kitchen and bathroom is essentially another small home from a plumbing standpoint.
It may need:
- Hot and cold water lines
- Kitchen plumbing
- Bathroom plumbing
- Toilet and shower connections
- Drain and vent piping
- Sewer connections
- Water heating
- Gas piping where applicable
- Laundry connections
If you are building an ADU, we can handle the plumbing installation!
New Commercial Construction Plumbing
Commercial plumbing has its own set of demands. A retail building is different from an office. A restaurant is different from a warehouse. A medical or professional space can have plumbing requirements that look nothing like either one.
We provide new commercial construction plumbing for projects requiring professionally installed water, waste, vent, sewer, gas, and fixture systems. Depending on the project, that can include restrooms, break rooms, utility sinks, water heaters, floor drains, commercial fixtures, service lines, and other plumbing infrastructure shown in the construction plans.
We understand that commercial construction also runs on coordination. The plumber is not working alone. There may be electricians, HVAC contractors, framers, concrete crews, drywall installers, inspectors, general contractors, and other trades moving through the same project. Good construction plumbing means doing our part correctly and keeping the project moving.
Plumbing Rough-In for New Construction
The rough-in stage is where a lot of the important work happens. It is also the stage most future homeowners will never see. Before walls are closed, we install and position the plumbing lines that will eventually serve sinks, toilets, showers, tubs, appliances, water heaters, and other fixtures.
Imagine standing inside a framed house. There is no drywall. No tile. No bathroom vanity. No kitchen cabinets. But the plumbing already needs to know exactly where those things are going.
A toilet drain cannot be approximately in the right spot. Neither can the shower valve. Accurate plumbing rough-in installation helps prevent conflicts and costly changes as construction progresses.
Underground Plumbing
Some of the most important plumbing work happens before the building looks much like a building at all. Underground plumbing may include portions of the building’s drain, waste, sewer, or water systems that need to be installed before the slab or other construction covers them.
Once concrete goes down, access becomes much more difficult. That makes layout and installation especially important during this phase.
- Measurements matter.
- Slope matters.
- Placement matters.
This is one of those stages where getting it right the first time is considerably easier than correcting it later.
Drain, Waste, and Vent Plumbing
Drain, waste, and vent systems are a major part of new-construction plumbing installations. These systems carry wastewater away while providing the venting necessary for drains to function properly. That is why these systems need to be carefully laid out and installed during construction.
New Sewer Line Installation
New construction may also require installation or connection of the property’s sewer line. The sewer lateral creates the path between the building’s drainage system and the appropriate sewer connection. This is another area where planning ahead matters because much of the work eventually ends up underground and out of sight. Our new sewer line installation services can be coordinated with the plumbing requirements of the overall construction project.
New Gas Line Installation
Building plans may include natural gas service for water heaters, ranges, dryers, fireplaces, outdoor kitchens, or other gas appliances. We provide gas line installation for new construction when it is part of the project’s plumbing scope. Gas piping needs to be properly sized and routed for the appliances it will serve. It is not something to improvise after the rest of the building has already been completed. Planning gas locations during construction can make appliance installation and future use much easier.
Fixture Installation and Plumbing Finish Work
Eventually, the project reaches the stage where it starts looking finished. Walls are painted. Cabinets are installed. Countertops go in. Then the plumbing fixtures begin turning empty rooms into usable spaces.
We can install and connect fixtures such as:
- Toilets
- Faucets
- Bathroom sinks
- Kitchen sinks
- Showers
- Bathtubs
- Garbage disposals
- Dishwashers
- Utility sinks
- Water heaters
This is where months of hidden plumbing work finally becomes something you can see and use.
New Construction Plumbing that Works with the Rest of the Job
Construction is a sequence. One trade affects another. If plumbing is installed in the wrong place, it can interfere with framing. If rough-ins are not ready when they need to be, another crew may have to wait. If something gets overlooked before drywall, somebody may have to open the wall again.
We understand that construction plumbing contractors need to communicate, coordinate, and complete work at the right stages of the build.
We work with builders, general contractors, property owners, developers, and other trades to help keep plumbing work aligned with the project.
Why Experience Matters in New Construction Plumbing
A repair plumber walks into an existing building and figures out what went wrong. A new construction plumber has a different job. We have to think about what could go wrong before the building is finished.
With more than 25 years of plumbing experience, 5 Star Plumbing, Heating, and Air brings practical, real-world plumbing knowledge to residential and commercial new construction projects.

Frequently Asked Questions
How much does plumbing cost for a new construction home?
The cost of new construction plumbing depends on the size and layout of the building, number of bathrooms and fixtures, piping materials, water heater selection, and complexity of the plumbing system. The best way to get an accurate number is to have the plans reviewed and receive a quote based on the actual project.
When does plumbing go into a new construction home?
Plumbing is completed in stages. Underground plumbing may happen early in the build, followed by rough-in plumbing once the structure is framed. After walls, cabinets, countertops, and other finishes are completed, plumbers return for fixture installation and final connections.
What is rough-in plumbing?
Plumbing rough-in is the stage when water lines, drains, vents, and connections for future fixtures are installed before drywall and other finished surfaces go in. It is one of the most important stages because much of this plumbing will eventually be hidden behind walls and beneath floors.
What type of pipe is best for new construction plumbing?
The right piping material depends on where it is being installed and what it will be used for. PEX and copper are common choices for water supply systems, while other materials are typically used for drain, waste, vent, and sewer piping. We can recommend appropriate materials based on the plans and requirements of the project.
When should I hire a plumber for a new construction project?
As early as possible. Getting the plumber involved during the planning stages can help identify potential layout problems before concrete is poured, walls are closed, or cabinets and finishes are installed. It is much easier to get the plumbing right the first time than relocate pipes later.
