Grocery store construction in Calgary is refrigeration construction with a store around it. The coolers, freezers and walk-ins, the compressor rack that runs them and the piping between them are usually the largest single part of the budget and the hardest to change once the floor is poured. Then come the prep rooms that need a food premises approval, the receiving dock and the floor drains. The sales floor, the part customers see, is the simplest part of the job.
Refrigeration racks and piping
Most grocery stores run their cases and walk-ins from a central refrigeration rack, a set of compressors in a machine room or on the roof, connected to every case by insulated refrigerant lines. The rack location, the pipe routes and the condenser on the roof are decided early, because they affect the roof structure, the electrical service and where the cases can go.
Refrigerant choices are changing as older refrigerants are phased down, and newer systems using CO2 or other low-impact refrigerants work at different pressures and need contractors who know them. We bring the refrigeration contractor into design at the start, so the case layout, the rack and the building are designed together.
The other early question is the floor. Cases often need drains, and some freezer areas need an insulated, heated slab so the ground below does not freeze and heave. In an existing building, cutting trenches for case drains and refrigeration lines is common and should be in the budget from day one.
Prep rooms and the AHS approval
A store that cuts meat, prepares food, runs a bakery or sells hot food needs those areas approved by Alberta Health Services as a food establishment. That means submitting the plans and the equipment list for review before construction, then passing an inspection before opening. Prep rooms need washable finishes, hand sinks, separate sinks for food and equipment, proper floor drains and, for cooking, an exhaust hood.
Our restaurant construction page explains the AHS plan review and the City's drawing checklist in more detail. A grocer's deli or hot food counter goes through the same process.
Receiving and loading
Groceries arrive every day, often by large truck. The store needs a receiving door with a dock leveler or a grade-level door, a back-of-house path that keeps deliveries off the sales floor, and enough room behind the store for trucks to back in. In a retail plaza, the landlord's rules may limit delivery hours and truck sizes.
Power and backup
A grocery store draws a lot of power for refrigeration, lighting and prep equipment. Check the building's electrical service before signing a lease, because a service upgrade can take months to arrange with the utility. Many grocers also want backup power or at least a plan for a power outage, since a few hours without refrigeration can cost the entire stock of perishables.
New store or existing building?
Many grocers in Calgary move into existing buildings: a former big-box store, a retail plaza anchor unit or a converted warehouse. That can be faster than building new, but the existing slab, roof and power need checking. Roofs have to carry the condensers and rooftop units. Slabs get cut for drains and piping. A change of use from another retail use to a grocery store usually does not need a development permit, but adding food preparation brings in AHS, and any change of use should be checked with the City before the lease is signed.
What a grocery store costs
| Project | Planning range (as of 2026, varies by scope) |
|---|---|
| New grocery store | $170–275 per sq ft |
The range moves mostly with refrigeration: how many cases and walk-ins, and the type of system. The prep rooms, the bakery and hot food areas, the receiving area and the condition of an existing building account for most of the rest. Fixtures and some equipment may be supplied by the grocer.

Energy use
Grocery stores use far more energy per square foot than most retail, mostly for refrigeration. Glass doors on reach-in cases, efficient compressors with variable-speed drives, heat reclaim from the refrigeration system to heat the store or the water, and LED case lighting all reduce the bill. Heat reclaim makes particular sense in Calgary, where the store needs heat for much of the year and the refrigeration system is rejecting heat all year.
Ask your refrigeration designer to compare the upfront cost of the efficient options with the yearly savings. Several of them pay back quickly in a store that runs every day.
Floors and finishes
Grocery floors take carts, pallet jacks, spills and constant cleaning. Polished concrete is popular for its durability and low maintenance, while vinyl or tile is common in prep and produce areas. Back-of-house floors need to be sealed and sloped to drains in wet areas. Walls in prep rooms need washable, impact-resistant finishes, and corner guards and wall protection save repairs where carts and pallets travel.
How long a grocery store takes
The schedule is usually set by the refrigeration equipment and the electrical service. Racks, cases and walk-ins are ordered early and installed in a set sequence: the rack and piping first, then the cases, then charging and testing the system before product arrives. The AHS review of the prep areas runs alongside the building permit, with an inspection before opening.
A conversion of an existing building can open sooner than a new build, provided the roof, slab and power are suitable. We check those three items before you commit, because each one can add months if it needs major work.
What grocers ask us
Do I need AHS approval for a grocery store?
If you prepare, cut or cook food on site, yes. The plans and equipment list go to Alberta Health Services for review before construction, and the store is inspected before opening. A store selling only packaged food has much less to do.
Can I put a grocery store in a former retail unit?
Often. Check the electrical service, the roof's capacity for refrigeration equipment, and whether the slab can be trenched for drains and piping.
Why does refrigeration cost so much?
It is a complete mechanical system of compressors, piping, cases and controls, designed and installed by specialists. In most grocery builds it is the largest single line item.
How long does it take to build a grocery store?
The refrigeration equipment, the electrical service and the AHS review usually set the schedule. We plan around those lead times from the start.
