A Vancouver renovation is the right time to plan the gas water heater's size, venting, and location properly, before walls close and decisions get locked in.

Quick answer
Renovations are the ideal window to reassess your gas water heater instead of just leaving it where it is, since sizing, venting routes, and clearances are far easier to change while walls and floors are already open. Coordinate this early with your contractor and CANRO so the water heater plan doesn't get finalized as an afterthought once other trades have already committed the space.

Once drywall goes up and flooring is finished, moving a water heater or changing its venting becomes a much bigger, messier job than doing it while the space is already open. If your renovation touches the kitchen, a bathroom addition, a basement suite conversion, or general mechanical upgrades, it's worth bringing a licensed gas contractor into the planning conversation early rather than treating the water heater as something to deal with after the design is locked.
A renovation often changes hot water demand -- an added bathroom, a second kitchen sink, a new laundry setup, or a basement suite all add draw that the existing water heater may not have been sized for. Rather than assuming the current unit will keep up, we look at the post-renovation fixture count and typical simultaneous use to size correctly, whether that means a larger storage tank or a tankless unit suited to the added demand.
We work directly with your general contractor or the trades coordinating the renovation, aligning our scheduling with framing, rough-in, and inspection stages so the water heater installation fits the overall project timeline rather than becoming a bottleneck. If your renovation is subject to BC Energy Step Code requirements for the jurisdiction, we're aware of how mechanical equipment choices factor into that and can discuss it in general terms with your contractor or designer as part of the planning.
A lot of Vancouver renovation work happens in older character homes and Vancouver Specials where the original mechanical room wasn't designed with today's fixture counts or appliance loads in mind, so a renovation is often the first real chance to correct undersized venting or a cramped equipment location. The City of Vancouver requires a permit for water heater installation or relocation as part of the renovation permit package, and coordinating that alongside your general building permit avoids a late-stage scramble. Vancouver's water supply is comparatively soft, coming through the regional Metro Vancouver system, which is a small but genuine factor in long-term tank performance worth mentioning if you're deciding between tank and tankless.
Even with good planning, renovations sometimes turn up something unexpected once walls or flooring are opened -- an older gas line that doesn't meet current sizing standards, venting that was never properly clearanced in the first place, or a water heater location that turns out to conflict with a new structural post or beam. When that happens, we'd rather flag it early and walk you through the options than quietly work around it, since a mechanical shortcut discovered later during final inspection can delay your whole project far more than addressing it head-on partway through.
If your renovation is being permitted in phases, or if the water heater work is happening ahead of other trades for scheduling reasons, tell us that timeline up front. We can sequence our part of the project, including any Technical Safety BC permit application, around what your general contractor needs rather than assuming a standard rough-in-to-finish schedule that may not match how your specific renovation is unfolding.
Safety note
During renovation work, if you ever smell gas near a water heater or a disconnected line, leave the area and call FortisBC's emergency line at 1-800-663-9911 from a safe location before anyone continues working nearby.
As early as the design or rough-in planning stage, ideally before walls close, so venting and gas line routing can be finalized alongside the other trades rather than retrofitted afterward.
Possibly -- it depends on total fixture count and expected simultaneous use across the renovated home, which is exactly what a sizing assessment during planning determines.
Often yes, but a renovation is a good opportunity to reassess whether the current location still makes sense given the new layout, venting requirements, and clearances.
Water heater work generally needs its own gas permit through Technical Safety BC alongside your City of Vancouver building permit -- we coordinate that as part of the project.
It's worth considering if space is tight or hot water demand is increasing, but it depends on gas line capacity and venting options in the new layout -- something we assess rather than assume.
Coordinate it with your contractor's rough-in and inspection schedule; we work around your project timeline rather than needing a fixed lead time on our own.
