Section 01
Approach geometry is the first constraint
Lane widths, boulevard trees, apron slope and the swing of the door all determine whether a long vehicle or a trailer can actually be manoeuvred into the building.
Measure the approach before believing a stall count. On mature lots with rear lanes this is frequently the binding limitation.
Section 02
Slab, drainage and floor finish
A garage floor carrying vehicles, lifts or heavy equipment needs adequate thickness and reinforcement, and Edmonton winters deliver a great deal of salted meltwater onto it.
Look for drains, sloped floors, sealed or coated surfaces, and check for cracking or spalling that indicates a slab under-specified for its use.
Section 03
Heating and ventilation determine year-round usability
In-floor hydronic heating, unit heaters and insulated overhead doors are the difference between a workshop and cold storage.
Ventilation matters equally: running engines, welding or finishing work require exhaust provision, and moisture from melting snow needs somewhere to go.
Section 04
Electrical capacity and equipment
Hoists, compressors, welders and EV charging all draw on service capacity. Sub-panel size, circuit provision and the age of the wiring should be documented.
Confirm the electrical work was permitted and inspected, particularly in detached structures added after the original build.
Section 05
Permitted size, use and insurance
Zoning limits accessory building size, height and site coverage, and county rules differ again for acreages. Unpermitted structures create insurance and financing complications.
Commercial or business use of a residential shop is a separate question with zoning and insurance implications; verify it rather than assume it.
