A heated garage build in Calgary relies on proper insulation, air sealing, and a heating system such as an overhead radiant tube or in-floor hydronic heat, so the space stays usable through Alberta's coldest months. Getting the insulation and ventilation right is what separates a garage that holds heat from one that wastes it.

Heated Garages in Calgary: The Complete Guide

In a city where January mornings hit -30°C, a heated garage isn’t a luxury — it’s genuinely life-changing. Here’s everything you need to know.

Heating System Options

1. In-Floor Radiant Heating (Best Option)

PEX tubing embedded in the concrete slab, heated by a boiler or electric system.

Pros: Most comfortable, even heat, melts snow off vehicles, quiet
Cons: Highest upfront cost, slow to respond to temperature changes
Cost: $12,000 – $20,000 for a typical 2-car garage

2. Forced Air Heater

Natural gas unit heater mounted near the ceiling.

Pros: Heats quickly, moderate cost, proven technology
Cons: Noisy, heats air (not floor), uneven temperature
Cost: $3,000 – $6,000 installed

3. Radiant Tube Heater

Long overhead tube that radiates heat downward.

Pros: Efficient, good for workshops
Cons: Hot spots, overhead clearance required
Cost: $2,500 – $5,000

4. Electric Baseboard

Simple electric heaters along walls.

Pros: Low upfront cost, easy install
Cons: High operating cost, limited output
Cost: $800 – $2,000

Insulation Requirements

A heated garage needs proper insulation or you’re just heating the atmosphere:

Walls: R-20 minimum (spray foam or batt + vapour barrier)
Ceiling: R-40 minimum
Slab: R-10 under the slab for in-floor heat
Garage door: R-16 minimum insulated door with good seals

Total Cost: Heated vs Unheated Garage

Item	Unheated	Heated
Base garage structure	$28,000 – $48,000	$28,000 – $48,000
Insulation (walls/ceiling)	Minimal	$6,000 – $12,000
Heating system	$0	$3,000 – $20,000
Insulated overhead door	Standard	+$500 – $1,500
Drywall & finishing	Optional	$4,000 – $8,000
Total	$28K – $48K	$42K – $90K

Frequently asked questions

How much does a heated garage build cost in Calgary?

It depends on size, insulation level, and the heating system you choose. Your fixed-price quote will vary based on your selections and square footage.

What is the best heating system for a Calgary garage?

Overhead radiant tube heaters and in-floor hydronic heat are both popular choices for Alberta winters, each with trade-offs in cost and comfort. We help you pick the system that fits how you use the space.

Do I need a permit for a heated garage in Calgary?

Yes, adding heating, gas, or electrical to a garage requires permits and inspection in Calgary. We manage that as part of the build.

Yes, without proper insulation and air sealing a heater will run constantly and still lose heat. We design the insulation and heating together so the garage is efficient and comfortable.
