Garages

It begins on paper. Detached garages in Calgary and in every surrounding municipality require a development permit and a building permit, and what you are allowed to build is governed by setbacks from the property lines and lane, maximum coverage of the parcel, maximum height, and rules that change on corner lots and on parcels without lane access. The design has to fit those constraints before anything else happens, and that is where we start.

Next comes the pad. A garage slab is a structural element, not a patio — thickness, reinforcement, a proper compacted base and thickened edges or footings below the frost line are what keep a structure from moving through Alberta's freeze-thaw cycle. Cutting the pad is the single most consequential place to save money badly, because everything above it is only as stable as it is.

Then framing and the envelope: walls, headers, trusses or a stick-framed roof, sheathing, and the door and window openings framed to the actual units being installed. From there it is the work we do every day — underlayment and ice-and-water membrane, flashing, shingles, house wrap, siding, soffit, fascia and seamless eavestroughs.

Finally the finishing: overhead door and opener, service door, trim, and the electrical rough-in and finish if the garage is being wired, which is its own permit and its own licensed trade. We coordinate that rather than pretending it is optional.

A single garage runs roughly 14 by 22 feet and holds one vehicle with narrow walking room around it. It suits a tight inner-city lot where the lane and setbacks leave nothing wider, and it is the minimum that will still take a full-size pickup lengthwise.

A double at roughly 20 by 22 is the Calgary default. Two vehicles fit; storage does not, which is the complaint we hear most often afterward. If the budget stretches, going to 24 by 24 buys enough depth for a workbench along the back wall without giving up either parking stall, and it is the single upgrade homeowners tell us they wish they had made.

Oversized and triple builds — 24 by 26 and up — start to be about what the garage is for beyond parking: a shop, a place for a trailer or a sled deck, or a heated space for actual winter work. Those decisions change the framing, the door sizing, the insulation and the electrical, so they belong in the conversation before the design goes to permit rather than after.

Height matters too and gets overlooked. A standard 8-foot wall gives you a 7-foot door and no room for a hoist or an overhead storage rack. Going to 9 or 10 feet is cheap while you are framing and impossible afterward. So is roughing in the wiring for a heater you plan to add in three years.

The rules that most often surprise homeowners are not the obvious ones. Maximum parcel coverage catches people who have already built a deck and a shed. Height is measured in a specific way that is not simply wall height. Lane-access parcels have different setbacks from front-drive ones. Corner lots carry sight-triangle restrictions. And on some parcels a restrictive covenant on title governs what can be built regardless of what the municipality would allow.

Outside Calgary the framework is the same but the numbers differ. Airdrie, Cochrane, Okotoks, Chestermere, Strathmore, Olds and Red Deer each set their own setbacks and coverage limits, and county parcels in Rocky View, Foothills, Mountain View and Red Deer County work to different rules again — often more permissive on size, sometimes stricter on siting relative to a septic field or a well.

We handle the applications as part of the job. That is not just a convenience: a garage built without permits is a problem that surfaces at exactly the wrong moment, when the house sells and a buyer's lawyer asks for the permit history. Unpermitted structures can force a retroactive application, a remediation order or a price reduction. Doing it properly the first time costs less than any of those.

Timelines are the honest caveat. Permit review sits with the municipality, not with us, and it is the least predictable part of any garage project. We start that clock as early as possible and give you the realistic range rather than the optimistic one.

A garage in this climate is not the same building as a garage in a mild one. Snow load has to be carried by the roof structure for months at a time, so truss and rafter specification is not a place to improvise. Wind exposure — especially on acreages and on the west side of the city where chinooks arrive first — drives sheathing, fastening and door selection.

The frost line is the other governing fact. Alberta's is deep, and anything bearing on soil above it will move as the ground heaves and settles through the year. Footings and thickened slab edges have to go below it. A garage on a shallow, unreinforced pad will crack, and the doors will stop closing squarely within a few seasons — which is the actual reason so many older lane garages sit visibly out of level.

The roof gets the same specification we would put on a house: ice-and-water membrane at the eaves and in valleys, synthetic underlayment, proper drip edge and flashing, and shingles nailed to the manufacturer's pattern. It is a small roof, which tempts corner-cutting, but a small roof over a car and everything else you own is not a place to cut corners.

And it needs eavestroughs. Garages are routinely built without them, and the result is a trench of runoff along the base of the wall, a pad edge undermined by erosion, and a lane that ices over every winter where the water runs across it.

Not every garage needs replacing. Plenty of Calgary lane garages are structurally fine and simply need the envelope redone: new shingles, new siding, new soffit and fascia, new eavestroughs. That is a fraction of the cost of a rebuild and, done in matching materials, it changes how the whole back of the property looks.

The economics work best when it rides along with house work. Crews, disposal and material delivery are already mobilized for the house re-roof, so adding the garage roof costs meaningfully less than booking it separately. The same applies to a re-side. If you are doing the house this year and the garage in three years, you will pay twice for the same setup.

Hail claims are the other common route. When a storm damages a house roof, the detached garage is usually damaged too — and it is frequently the thing left off the claim because nobody inspected it. We inspect and document both structures as one property, which is what an adjuster needs in order to approve both.

Where a garage genuinely is past saving — a shifted or cracked pad, rotted bottom plates, a sagging roof structure, framing that was never square — we will say so plainly rather than sell an envelope job over a structure that will not hold it.

Detached garages are the norm across Calgary's older lane-access neighbourhoods — Bowness, Renfrew, Killarney, Inglewood, Mount Pleasant, Bridgeland, Highland Park, Marda Loop — where the original single garage from the 1950s is now too small for a modern vehicle and too far gone to keep. Replacing one is among the highest-return exterior projects on those lots.

In the suburbs and the surrounding towns, detached builds are usually about capacity: a second structure for a truck, a trailer, a boat, or a workshop that the attached garage cannot house. Airdrie, Chestermere, Cochrane, Okotoks, Langdon, Strathmore, Crossfield, Carstairs, Didsbury, Olds, Innisfail and Red Deer all see steady demand for exactly that.

On acreages the brief changes again. Rocky View, Foothills, Mountain View and Red Deer County parcels have room for larger structures and fewer coverage constraints, but siting has to account for the well, the septic field, the approach a concrete truck can actually use, and wind exposure with nothing around to break it. We plan those builds against the site rather than against a standard drawing.
