Our Garage Building Process

Our Garage Building Process

The Garage Building Process (In Detail)

It Starts With a Needs Assessment

We prepare our quotes on-site in order to ensure accuracy. During this visit we will determine

  • The size, shape, restrictions place on your garage by your property
  • Features of the garage, including storage, lighting, etc.

We will also show example styles, finishings, etc. to help you visualize your new garage.

Once we have your approval for the quote, we move on to the next step.

Garage Size, Shape, & Legalities

Allowable size is determined by lot size, existing home size, easements, utility right of ways, property lines and zoning.

Generally 45% lot coverage is allowed and garage must be at least 2’ from rear property line and 2’ from side property lines. The garage can be built right on side property line with maintenance free materials and fire-rated materials.

We ensure your garage meets all codes & requirements.

Garage Planning & Obtaining Permits

We prepare and submit site plan showing proposed garage on your property, elevation, floor plan, electrical plan, and cross section plans.

For garages over 55m2 (592 sq ft) foundations need to be either 4’ deep on footings or engineered stamped foundation design (prepared and planned for by Raintree).

All necessary plans and permits are prepared and obtained by Raintree on your behalf.

Next, We Start Building Your Garage

With all the appropriate permits and materials on hand, we get to work.

Garage Foundation


We excavate and pour footings, dig the electric/gas trenches, form and pour stem walls (backfill when complete), and pour the concrete pad.

Garage Framing


With the foundation in place, we frame the walls and trusses.

Garage Finishing


The roof is installed, electrical/gas lines installed, and finishing materials (siding, soffit, fascia, eavestrough, vapour barrier, insulation, drywall/etc.) are installed.

Completion & Delivery


Once the build is completed, we will perform an inspection with you and then provide you the keys to your new garage!

Garage Foundation

The most important building step in the garage process. Raintree Contracting is an experienced concrete placing/finishing company that prides itself on performing this critical step to high standards. Learn more about us.

Most garages are built on footing and stem walls (walls 1-4 feet tall). Foundation must be square and strong to ensure framing goes well. Walls are formed using a cam-lock wall system. Concrete stem walls ensure wood framing sits above grade and away from snow piles, melting snow, rain water, etc and can also serve as retaining walls for sloped backyards.

Garage Foundation Plans

Foundation Notes

  • Other foundation methods, such as monolithic footings and stub walls, will need to be stamped and engineered as appropriate to meet building needs.
  • The garage pad is planned to sit higher than the grade of the alley to ensure no water enters the garage. A concrete apron links the elevation change from the alley to the pad.

Concrete Pad

For years of service/strength Raintree is very particular about the finish, coatings, and workmanship of concrete flat work.


  1. Base layer of compacted gravel
  2. Concrete is poured with specific mix design, rebar placement, and in-house developed screed techniques which ensure strength and flatness.
  3. Flatwork is never “polished” as it contains entrained air in the mix for frost protection. Rather it is machine leveled and smooth troweled and coated with cure and seal.
  4. Cure and seal: protects concrete during the chemical curing process and provides an easy to clean surface and protection from road salt etc in the future.
  5. Contraction/relief joints are saw-cut the day of the pour or the immediate days following pour to control shrinkage cracking.

Garage Framing

Garages are built using 2×4 or 2×6 spaced on 16”oc or 24”oc based on requirements such as size, height, insulation needs, loads and customer preference.

Max wall height is 9’10” and max overall garage height is 15 feet under a standard garage permit.

Overhead door beam is an engineered LVL beam with specifications that match the individual garage load/structural requirements.

Roof Framing

There are many roof framing designs available. Choosing a roof impacts the aesthetic appearance as well as the functional ability (storage, headroom, etc).

Most versatile option is the gable roof and reverse gable (gable is flipped and eaves are over top the garage door). Main gable truss options are standard trusses, storage trusses, and scissor trusses.

Roof Truss Example Drawing

Choose From Different Types of Available Roof Trusses

Standard pre-manufactured trusses.

Storage trusses have an open box design in the center when coupled with an access door complete with ladder provides attic storage.

Scissor trusses raise the ceiling height to allow for maximum headroom.

Roofing, Siding, & Garage Door

Garage Roofing


The roof is covered in underlayment, aluminum flashing/drip edge is installed, and shingles are installed. Shingles are usually an architectural shingle, 3 tab shingle, or a shingle matching the home (cedar, clay, etc).

Roof vents are installed to ventilate the attic space – they work together with soffit venting.

Garage Siding

Siding, Soffit, & Fascia

Low maintenance aluminum materials, colour matched to your home, are used for soffit/fascia. Soffits are vented except when close to property lines as per code. Siding is typically matched to existing home siding and can be vinyl siding (common), hardie board, acrylic stucco, wood panel.

Tyvek/house wrap helps keep air/water out while letting water vapour escape. The garage is wrapped prior to exterior siding.

Garage Door

Overhead Garage Door

Planned and sized to fit with typical sizing: 16’ for double doors, and 9’ for single door. Most garages have historically been fitted with a 7’ tall door but more common these days is 8’ tall doors to accommodate larger vehicles like trucks/suv’s.

Insulated panels are painted to homeowner’s preference and matching garage man door.

Garage Electrical & Gas Lines

Simple standard electrical involves running a 30A line from the home’s electrical panel and installing lights, receptacles, and low voltage wiring for garage door.

Upgraded or shop use electrical runs a 60A line from the home to a subpanel in the garage. Receptacles, lighting, etc is run off this subpanel. The subpanel has open breakers for adding lines in the future.

Electrical options include overhead fluorescent light fixtures, 220V receptacle, exterior GFI plugs, motion sensor lighting, heater receptacle, higher amp workbench receptacles.

Electrical is roughed in and then finished after garage is complete.

Gas line: a gas line can be run from the home to the garage in the same trench for immediate or later installation of a garage heater.
