Auto Repair Shop Construction in Calgary

An auto repair shop looks like a simple industrial bay until you plan where the lifts go. Then the slab, the drains, the power, the air and the exhaust all have to line up with them. We build new mechanic shops and fit out industrial bays for auto repair in Calgary, and we start every project from the lift layout, because almost everything else follows from it.

The slab and the lifts

Vehicle lifts concentrate heavy loads on small anchor points. Plan on a reinforced slab at least 6 inches thick for most lifts, with the exact thickness and reinforcement set by the lift manufacturer and a structural engineer. Heavy-duty or in-ground lifts may need their own footings or pits.

On an existing bay, this is the first thing we check. Many older industrial slabs are thinner than a lift needs, or have cracks and joints in exactly the wrong places. Cutting out and re-pouring a section of slab under each lift is a common, and commonly forgotten, line item. If lift locations matter, we test the slab before you sign the lease.

Plan the lift positions before you sign the lease, not after. The slab decides more of the budget than the lifts do.

Floor drains and oil/water separators

Shop floors collect oil, coolant, washwater and Calgary road slush. Floor drains in a repair shop have to run through an oil/water separator before they reach the sewer, so contaminants are captured instead of discharged. As of 2026, plan on about $15,000 to $35,000 for an oil/water separator serving roughly eight bays, depending on size and site conditions.

The drain layout needs as much care as the lifts. Trench drains in front of each bay catch meltwater coming off vehicles in winter, and the floor needs to slope to them. Floor drains and separators require plumbing permits, and the separator needs regular maintenance once the shop is open.

Power, air and exhaust

A modern shop runs on power and compressed air:

• Electrical service: many shops need a 3-phase, 400-amp service for lifts, compressors, welders, tire equipment and EV charging. Upgrading the service is often the biggest single electrical cost, and the utility's lead time can set the schedule.
• Compressed air: a compressor room, with air lines and drops at every bay, sized for the tools you run at the same time.
• Vehicle exhaust extraction: hose reels or rails that capture exhaust at the tailpipe while engines run indoors.
• Ventilation and heating: general ventilation for fumes, and heating that recovers quickly after the doors open, usually radiant tube heaters in Calgary shops.

Overhead doors and the building envelope

Insulated overhead doors are a must in Calgary. Every time a door opens in January the bay loses heat, so door size, insulation, seals and fast operators all affect your heating bill and your technicians' comfort. Size the doors for the largest vehicles you service, including lifted trucks and vans with roof racks.

Fire separations, ventilation and flammable storage

A repair garage is treated differently under the building code from a warehouse or an office. Expect fire separations between the shop and the customer area or offices, ventilation to control vehicle exhaust and fuel vapour, and limits on storing flammable liquids such as waste oil and solvents. In a multi-tenant building, separations from the neighbouring units matter too.

When a repair shop moves into an industrial unit approved for another use, a Change of Use development permit is usually needed before the building permit. We confirm the land use and the approved use before you sign.

What we check on a site walk for a repair shop

Before you sign a lease on an industrial bay for auto repair, these are the things we look at, because each one can change the budget more than the finishes ever will.

• The slab: thickness, reinforcement, cracks and joint locations where the lifts will go. If we cannot confirm the slab from drawings, we recommend coring it.
• The drains: whether the bay has floor drains at all, where they discharge, and whether there is room for an oil/water separator with access for the pump truck.
• The electrical service: the panel size and voltage. A single-phase service sized for a warehouse tenant is a common, expensive surprise.
• The doors: height, width and condition of the overhead doors, and whether the opening can be made bigger without structural work.
• The ceiling height: enough clearance for a vehicle at full lift height, plus lights and heaters above it.
• The neighbours: air tools and compressors are loud. A shared wall with an office tenant often needs sound control, and many landlords set quiet hours.
• The approved use: whether the unit is already approved for vehicle repair, or whether a Change of Use is needed.

The most common mistake we see is a shop that plans the lift positions after the lease is signed and finds the slab will not take them. It is also worth planning for growth. Adding a lift or an alignment bay later is far cheaper if the slab, the conduit and the air lines were sized for it from the start.

What does it cost to build an auto repair shop in Calgary?

As of 2026, a complete eight-bay auto repair shop of about 6,000 square feet plans at roughly $900,000 to $1.5 million to build. Lifts, drains and power decide where in that range a shop lands.

A fit-out of an existing industrial bay costs less than a new building, but the slab, the service size and the drains decide how much less.
