Secondary suite plumbing & gas fitting in Kelowna
Adding a suite? The plumbing and gas go in early and are the hardest to change later. We plan the kitchen, bathroom, laundry, hot water and gas so the suite works for both households and is ready for inspection.

Quick answer
For secondary suite plumbing in Kelowna, call Anderson Plumbing and Gas Fitting at (250) 859-3548. We rough in the suite kitchen, bathroom and laundry, plan hot water for two households and run gas lines, under permit, alongside your contractor.
A suite is a second household under the same roof. That means a second kitchen and bathroom tied into the existing drains, enough hot water for two households, shut-offs so one unit can be worked on without cutting water to the other, and any new gas appliances sized against the whole house. Customers' Google reviews include a basement suite renovation, and we plumb garden suites too; a detached garden suite or carriage house has its own rules, so your designer should confirm which apply.
How the job runs: we start from your layout, where the suite kitchen, bathroom and laundry go and where they can tie into the existing drains. You get a fair, upfront price for the plumbing and gas. We pull the gas permit, rough in and test before the walls close, then come back at the end to set the fixtures and test everything again.
What moves the price: how far the new fixtures are from the existing drains, whether the slab or floor has to be opened for drain lines, the hot water plan (one larger heater or a second one for the suite), how many gas appliances the suite adds and whether the gas line or meter needs upgrading, and whether we supply the fixtures or you do.

City of Kelowna suite bulletin
Bulletin 26-01 (updated April 14, 2026) says suite heating must be locally controlled, and a furnace shared by both units needs separate thermostats and zone control dampers. Hardwired, interconnected CO alarms are required where there is a fuel-burning appliance or an attached garage, and owners are told to contact their water district and FortisBC before construction.
Source: kelowna.caWhat to decide before rough-in
- Where the suite kitchen, bathroom and laundry will go
- One water heater for both units, or a second one for the suite
- Which gas appliances the suite will have, if any
- How the suite will be heated and controlled
- Separate shut-offs for each unit
- Whether you are supplying the fixtures or we are
Planning the suite plumbing
The decisions that are cheap on paper and expensive once the walls are closed.
Drain locations
Suite fixtures have to slope to the existing drains. The further they are from those lines, the more floor gets opened, so keep wet areas close together where you can.
Hot water
Count the showers that could run at once across both units. That decides whether one larger heater will keep up or the suite needs its own.
Gas load
A suite range, dryer or fireplace adds load to the same meter and line. We total it before quoting; if the meter needs upgrading, we arrange it with FortisBC, which owns the meter.
Heating control
The City requires suite heating to be locally controlled. Settle the heating plan with your designer early; we handle the gas side of it.
Shut-offs
Separate shut-offs let either unit be worked on without cutting water to the other household.
Permits
The suite needs a building permit. We pull the gas permit for the gas work. Inside Kelowna, the City of Kelowna issues most natural gas permits. Propane work, and all gas work in West Kelowna, Lake Country, Vernon, Peachland and Oyama, is permitted through Technical Safety BC.

Questions, answered
Does a suite need its own hot water tank?
Not always. It depends on the size of both households, the layout and how you want to split utilities. We size the hot water so neither unit runs out, whether that means one larger unit or a second one for the suite.
Can the suite share the main house furnace?
The City's suite bulletin requires suite heating to be locally controlled. For a shared furnace that means separate thermostats and zone control dampers, and the bulletin has more detail your designer will need. We handle the gas side of whichever plan you choose.
Who pulls the permits?
We pull the gas permit for the gas work. The building permit for the suite, which covers the plumbing, goes through you, your designer or your contractor, and we tell you what our part needs. Inside Kelowna, the City of Kelowna issues most natural gas permits. Propane work, and all gas work in West Kelowna, Lake Country, Vernon, Peachland and Oyama, is permitted through Technical Safety BC.
When should I bring you in?
At the layout stage, before framing is done. Moving a suite bathroom a few feet closer to the existing drains on paper costs nothing; moving it after the floor is cut does.
Will you work with my contractor?
Yes. We take the plumbing and gas portion and work to the contractor's schedule, or work directly for you if you are managing the project yourself.
