A new build lets the mechanical room, gas line, and venting be planned from scratch, opening up more genuine tank vs. tankless choice.

Quick answer
A new build in Maple Ridge gives homeowners a real, open choice between a natural-gas storage tank and a tankless unit, since the mechanical room, gas line, and vent path can all be designed around whichever option is chosen rather than retrofitted into existing constraints. The decision usually comes down to household size, expected simultaneous hot water use, and available mechanical space on the plans. Getting this decided before the mechanical rough-in avoids costly changes later in the build.

Most water heater conversations CANRO has in Maple Ridge involve replacing an existing unit within whatever space and venting the original installer chose years ago. A new build removes that constraint entirely: the mechanical room can be sized, the vent path planned, and the gas line run specifically for whichever water heater configuration the homeowner actually wants, rather than working around what is already there.
This is the point in a build where the tank-versus-tankless decision should genuinely be made, since it affects the mechanical room's dimensions and the framing around it.
Both a traditional gas storage tank and a tankless unit are viable in a new build, and the right one depends more on household size and habits than on either being universally better.
| Factor | Storage Tank | Tankless |
|---|---|---|
| Footprint | Larger, needs dedicated floor space | Compact, wall-mounted |
| Simultaneous use | Limited by tank volume once drained | Continuous while within its rated flow |
| Best fit | Larger households, multiple bathrooms at once | Space-constrained mechanical rooms, steady demand |
| Mechanical room impact | More square footage allocated | Frees floor space for other use |
Neither choice is a mistake in a new build; it is a matter of matching the unit to how the household will actually use hot water.
New builds sometimes include more bathrooms, larger soaker tubs, or multiple-head showers than older homes were typically built with, which increases peak hot water demand. Sizing the water heater against the home's actual fixture list, including any high-flow features, matters more here than guessing based on square footage alone.
Because Maple Ridge new-build lots range from flatter areas to sloped lots near the foothills, the mechanical room's location relative to an exterior wall affects how straightforward the vent run will be. Planning this alongside the rest of the mechanical drawings, rather than after framing is complete, keeps the vent path short and avoids routing it through multiple floors or tight framing cavities.
A condensing tankless or high-efficiency tank also needs a condensate drain, which should be planned into the plumbing rough-in rather than added as a workaround later.
On most new builds, the general contractor coordinates the mechanical trades, but the homeowner still benefits from confirming directly that the water heater configuration matches what was actually discussed, since standard builder specs do not always reflect a homeowner's specific preference for tank versus tankless. Raising this early, ideally at the mechanical design stage, is far easier than requesting a change once the gas line and venting are roughed in.
Whoever performs the gas fitting work needs to be a Technical Safety BC licensed gas fitter, and the permit is handled through the City of Maple Ridge as part of the overall construction permit package.
Safety note
Gas water heater installation in a new build must be performed by a Technical Safety BC licensed gas fitter, with venting and gas line sizing confirmed against the home's actual fixture count. If you ever smell gas near the mechanical room, leave the home and call FortisBC at 1-800-663-9911 from outside.
Yes, and a new build is actually the easiest scenario to make that choice, since the mechanical room and venting can be designed around whichever option you prefer rather than retrofitted later.
Not automatically; it depends on the number of bathrooms, fixture types, and household size on the actual plans, not just the fact that the home is new construction.
Before the mechanical rough-in, ideally at the design stage, since the decision affects the mechanical room's dimensions and the plumbing and gas line routing planned into the walls.
Not necessarily; standard specs are often a default rather than tailored to your preferences. It is worth confirming directly with the builder or mechanical designer rather than assuming it matches your expectations.
If it is a high-efficiency condensing unit, yes, and this should be planned into the plumbing rough-in during construction rather than added as a workaround after the home is finished.
This is typically coordinated by the general contractor as part of the overall construction permit package through the City of Maple Ridge, but the actual gas fitting work must be done by a Technical Safety BC licensed gas fitter.
