A plane hangar is a purpose-built enclosure that protects aircraft from weather, enables maintenance, and satisfies airport authority requirements for based aircraft. Pre-engineered steel is the dominant construction method for plane hangar buildings in Canada because wide clear-span frames eliminate interior columns, giving unobstructed floor space for wings and tail assemblies. This guide covers every major decision a Canadian owner, operator, or FBO faces when planning a new hangar, from structure type and door selection through permits, cost drivers, and the procurement process.
Key takeaways
- Clear-span steel frames are the standard for hangars because they provide column-free interiors wide enough for most general aviation and regional aircraft.
- Door type is the single largest variable in hangar design; it affects structural loading, slab requirements, and operational cost.
- Canadian hangars must meet the National Building Code snow and wind load requirements for their specific climate zone, plus Transport Canada and local airport authority rules.
- Site preparation, foundation, and utility connections are typically the largest cost drivers after the steel package itself.
- Lead times for engineered steel packages can range from several weeks to several months depending on complexity and supply conditions; early engagement with a supplier is advisable.
Definitions & scope
The term “plane hangar” covers a wide range of structures, from a single-bay T-hangar storing one light sport aircraft to a multi-bay executive or commercial facility housing business jets or turboprops. For the purposes of this guide, the focus is on privately owned or FBO-operated general aviation hangars built on Canadian airports, private airstrips, and agricultural properties with grass or gravel strips.
Pre-engineered metal buildings (PEMBs) are factory-fabricated structural steel frames, secondary framing, and cladding systems that are engineered to a specific load set and then bolted together on site. They differ from conventional steel buildings, which are designed and fabricated from raw steel sections on a project-by-project basis. Both approaches are used for hangars, but PEMBs dominate the general aviation segment because of faster delivery, lower erection cost, and predictable engineering documentation for permit submissions.
Key terms used throughout this guide:
- Clear span: A framing system with no interior columns between the exterior walls.
- Eave height: The vertical distance from the finished floor to the point where the roof and wall meet; critical for tail clearance.
- Door rough opening: The framed width and height available for the hangar door system.
- Dead load / live load / snow load: Structural load categories defined in the National Building Code of Canada (NBC).
Why this matters
Canada has one of the largest general aviation fleets in the world relative to population, with aircraft operating across climates that range from the mild Pacific coast to the severe prairie winters and the Atlantic’s high wind and ice-loading environment. An aircraft left outside in a Canadian winter faces accelerated corrosion from road salt aerosols, hydraulic fluid thickening, battery drain, and potential airframe damage from ice accumulation. A properly designed hangar eliminates most of these risks and can meaningfully extend airframe life.
Beyond aircraft protection, hangars serve regulatory and insurance functions. Many airports require based aircraft to be hangared as a condition of tie-down agreements. Insurance underwriters frequently offer lower premiums for hangared aircraft. For commercial operators, Transport Canada’s Canadian Aviation Regulations (CARs) impose maintenance environment requirements that a hangar helps satisfy.
The construction decision is significant because a hangar is a long-lived asset. Steel buildings, when properly maintained, routinely serve 40 to 60 years or more. Choosing the wrong structure type, door system, or eave height at the outset creates operational constraints that are expensive to correct later. Getting the design right before breaking ground is therefore the highest-leverage decision in the entire project.

Your options
Clear-span pre-engineered steel hangar
What it is: A rigid steel frame engineered to span the full width of the building without interior columns. The frame is fabricated in a factory, shipped to site, and bolted together by an erection crew.
How it works: Tapered or straight I-beam rafters carry roof loads to exterior columns. Secondary framing (purlins and girts) supports the steel cladding. The entire package is engineered to the site-specific NBC load requirements for snow, wind, seismic, and dead loads.
Best for: Single-engine piston aircraft up to large turboprops and light business jets; widths from roughly 40 ft to 150 ft or more are achievable. This is the most common hangar type in Canadian general aviation.
Limitations: Very wide clear spans (beyond approximately 150 ft) require heavier frames and deeper rafters, increasing cost. Eave heights must be specified carefully to accommodate the tallest aircraft’s tail height plus door system clearance.
Multi-bay modular hangar
What it is: A series of bays sharing interior columns at regular intervals, creating a row of individual aircraft stalls under one roof.
How it works: Interior columns reduce the span each frame must bridge, allowing lighter steel sections. Individual bays typically have their own door openings.
Best for: Airport operators or municipalities housing multiple small aircraft (typically single-engine piston or light sport) where individual ownership of each bay is the business model. T-hangar configurations are a specific variant of this approach.
Limitations: Interior columns limit flexibility; the building cannot easily be reconfigured for larger aircraft later. Not suitable for aircraft with wide wingspans that exceed the bay width.
Conventional structural steel hangar
What it is: A hangar designed and fabricated from standard or custom steel sections by a structural engineer on a fully bespoke basis, rather than from a pre-engineered system.
How it works: A structural engineer designs the frame from first principles. Steel is procured and fabricated to those drawings. Erection is typically performed by a structural steel contractor.
Best for: Very large commercial or military hangars where spans exceed what a standard PEMB catalogue can accommodate, or where unusual geometry, heavy crane loads, or complex code requirements make a custom approach necessary.
Limitations: Higher design and fabrication cost, longer lead times, and more complex procurement than a PEMB. Generally not cost-effective for general aviation hangars under approximately 20,000 sq ft.
Fabric-clad steel frame hangar
What it is: A steel primary frame covered with a tensioned fabric membrane rather than steel cladding panels.
How it works: The structural frame is similar to a PEMB, but the cladding is a coated fabric (typically PVC or HDPE) that is tensioned over the frame. Natural light transmission through the fabric can reduce daytime lighting costs.
Best for: Temporary or semi-permanent hangars, remote airstrips where shipping heavy steel cladding is costly, or applications where natural light is a priority.
Limitations: Fabric membranes have a shorter service life than steel cladding and require periodic replacement. Thermal performance is generally inferior to insulated steel panels. Not suitable where a permanent, fully insulated structure is required.
Hybrid wood-frame and steel hangar
What it is: A structure combining a wood post-and-beam or engineered wood frame with a steel roof system or steel cladding.
How it works: Wood framing handles wall loads; a steel truss or beam system spans the roof. Common in agricultural settings where a private grass strip is adjacent to a farm.
Best for: Small private hangars on agricultural properties, particularly where local lumber supply is abundant and the owner has construction experience with wood.
Limitations: Wood is susceptible to moisture, rot, and pest damage in hangar environments where aircraft fluids and condensation are present. Clear spans are more limited than steel. Insurance and resale considerations may favour an all-steel structure.

Options compared
| Structure type | Best for | Typical clear span range | Durability / key limitations |
|---|---|---|---|
| Clear-span PEMB | Most GA aircraft; single or small fleet | 40 ft to 150+ ft | 40-60+ year lifespan; eave height must be specified correctly at design stage |
| Multi-bay modular | Airport T-hangar rows; multiple small aircraft | Per bay: 40-60 ft typical | Durable but inflexible; interior columns limit future reconfiguration |
| Conventional structural steel | Large commercial / military hangars | 150 ft to 300+ ft | Very durable; higher cost and longer lead time than PEMB |
| Fabric-clad steel frame | Temporary / remote / agricultural | 40 ft to 100 ft typical | Fabric membrane requires periodic replacement; lower thermal performance |
| Hybrid wood and steel | Small private agricultural hangars | Up to ~60 ft | Moisture and pest risk; limited clear span; may affect insurance terms |
For most Canadian general aviation owners, the clear-span PEMB is the practical default. It delivers the widest column-free floor area for the cost, comes with engineered drawings suitable for permit submission, and has a service life that matches or exceeds the useful life of the aircraft it protects. Multi-bay modular configurations make sense when an airport authority or municipality is developing a row of individual rental stalls. Conventional structural steel and fabric structures serve niche applications where the PEMB envelope does not fit the requirement.
How to choose
The right hangar type follows directly from the aircraft being stored, the site constraints, and the intended use of the building.
Choose a clear-span PEMB if you are storing one or a small number of general aviation aircraft ranging from a light sport to a turboprop or light business jet, you want a permanent insulated structure with a long service life, and you need engineered drawings for a building permit. This covers the majority of private and FBO hangar projects in Canada.
Choose a multi-bay modular configuration if you are an airport operator developing rental T-hangar stalls for multiple tenants, each storing a single-engine piston aircraft, and individual bay ownership or rental is the business model.
Choose conventional structural steel if your aircraft fleet includes wide-body or large turbofan aircraft requiring spans beyond approximately 150 ft, or if the project involves heavy overhead crane systems, complex geometry, or other requirements that exceed a standard PEMB catalogue.
Choose a fabric-clad structure if the hangar is intended to be temporary or semi-permanent, the site is remote and shipping heavy steel cladding is prohibitively expensive, or natural light transmission is a specific operational requirement.
Choose a hybrid wood-and-steel structure only if the aircraft is small (single-engine piston or light sport), the site is an agricultural property, local lumber is the most practical material, and you have confirmed that your insurer accepts the construction type for aircraft storage.
In all cases, confirm the required eave height before finalizing the frame. A common mistake is specifying eave height based on the aircraft fuselage height without accounting for the door system’s header depth, which can consume 12 to 24 inches of the rough opening.
Costs & timelines
No verified current price data has been supplied to this guide. The following describes cost drivers in ranked order; for indicative budget ranges, see the Aircraft Hangar Cost in Canada guide and the Metal Building Prices and Cost in Canada guide.
| Rank | Cost driver | Why it matters |
|---|---|---|
| 1 | Building size (footprint and eave height) | Steel tonnage scales with floor area and frame height; larger buildings cost more in absolute terms but often less per square foot |
| 2 | Door system type and width | Hydraulic bifold and hydraulic bottom-rolling doors carry significant equipment and structural costs; a wide door opening also requires a heavier header beam |
| 3 | Foundation and slab | Hangar slabs must support aircraft loads and often fuel equipment; frost depth varies significantly across Canada, affecting footing depth and cost |
| 4 | Insulation and interior finish | A heated maintenance hangar requires vapour barrier, insulation, and HVAC; an unheated storage hangar does not |
| 5 | Site preparation and access | Grading, drainage, apron paving, and taxiway connections vary widely by site condition |
| 6 | Regional snow and wind load zone | Higher design loads (e.g., Atlantic Canada, northern Ontario, prairie wind zones) require heavier steel sections |
| 7 | Erection labour market | Labour rates and availability differ by province and season; remote sites add mobilization cost |
Timeline drivers include engineering and permit approval duration (which varies by municipality and airport authority), steel fabrication lead time, and erection crew scheduling. Engaging a supplier early in the planning process allows permit drawings to be prepared while fabrication lead times are being confirmed. For a detailed look at erection cost components, see the Steel Building Erection Cost in Canada guide.

Risks & common mistakes
Underspecifying eave height. The most common design error in hangar projects is choosing an eave height based on the aircraft’s published height without accounting for the door system header, the slab thickness above grade, and any overhead equipment such as a hoist or lighting fixtures. A tail that clears the door opening by only a few inches creates daily operational stress and limits the ability to store a taller aircraft in the future.
Choosing the wrong door system for the climate. Hydraulic bifold doors are fast and convenient but contain fluid systems that require winterization and maintenance in cold climates. Sliding doors are mechanically simpler but require clear space along the building face. Selecting a door system without considering the local temperature range, wind exposure, and available apron space is a frequent source of post-construction regret. The Hangar Door Types guide covers this decision in detail.
Ignoring airport authority requirements. Many Canadian airports have design standards for hangars built on leased land, including setback requirements, apron grades, fuel system specifications, and aesthetic guidelines. Failing to engage the airport authority early can result in costly redesigns or permit refusals.
Underestimating foundation cost. Hangar slabs are not standard commercial slabs. They must accommodate point loads from aircraft jacks, fuel trucks, and tow vehicles. In frost-prone regions, the footing depth and perimeter insulation requirements add cost that is sometimes omitted from early budget estimates.
Not accounting for future aircraft. An owner who plans to upgrade from a piston single to a turboprop within five years should size the hangar for the future aircraft, not the current one. Adding width or eave height after construction is significantly more expensive than building correctly the first time.
Skipping the permit process. Some private airstrip owners attempt to build hangars without permits, particularly in rural areas. This creates title encumbrances, insurance complications, and potential enforcement action. For a full overview of the permit process, see the Steel Building Permits in Canada guide.
How the process works
- Define the requirement. Identify the aircraft to be stored (current and anticipated future), the intended use (storage only vs. maintenance), heating requirements, and any airport authority design standards that apply to the site.
- Engage a steel building supplier for preliminary design. Provide the aircraft dimensions, site location (for load zone data), and door preference. The supplier produces a preliminary layout and frame specification. Titan Steel Buildings offers this service for Canadian projects; visit the Aircraft Hangars page for an overview of available configurations.
- Obtain site-specific engineering and permit drawings. The supplier’s engineering team produces stamped drawings to the NBC load requirements for the site’s climate zone. These drawings are submitted to the local building authority and, where applicable, the airport authority.
- Prepare the site and foundation. Grading, drainage, and concrete work are completed by a local contractor. The hangar slab is typically poured and cured before the steel package arrives. Anchor bolt placement must match the engineered drawings exactly; see the Steel Building Anchor Bolts guide for tolerances and common errors.
- Receive and erect the steel package. The fabricated steel package is delivered to site. An experienced erection crew assembles the primary frame, secondary framing, and cladding in sequence. Door systems are typically installed as part of the erection scope or immediately after.
- Complete mechanical, electrical, and interior fit-out. Heating, lighting, electrical panels, floor drains, and any interior finishes are installed. A heated maintenance hangar requires coordination between the mechanical contractor and the building envelope specification.
- Final inspection and occupancy. The local building authority conducts a final inspection. The airport authority (if applicable) may conduct a separate acceptance inspection before the hangar is connected to the taxiway system.

Frequently asked questions
What size hangar do I need for a Cessna 172 or similar single-engine piston aircraft?
A Cessna 172 has a wingspan of approximately 36 ft and a height of approximately 8.9 ft. A single-bay hangar with a 42 to 50 ft clear-span width and an eave height of 12 to 14 ft provides comfortable clearance for the aircraft and the door system. If you plan to store two aircraft side by side or anticipate upgrading to a larger aircraft, sizing up to 60 ft wide is a common recommendation. Always verify the door rough opening height against the aircraft’s tail height plus door header depth.
Do I need a building permit for a private hangar on my own property?
In virtually all Canadian jurisdictions, a building permit is required for a permanent hangar structure regardless of whether it is on airport land or a private agricultural property. The permit process involves submission of engineered drawings stamped by a licensed engineer registered in the province where the building will be constructed. Some rural municipalities have simplified processes for agricultural buildings, but aviation structures are typically treated as commercial or industrial buildings. Confirm requirements with your local building authority before beginning design.
What is the difference between a T-hangar and a box hangar?
A T-hangar is a multi-bay configuration where individual stalls are arranged in a row, each shaped roughly like the letter T when viewed from above, allowing aircraft tails to nest between adjacent bays and reducing the overall building footprint. A box hangar is a single rectangular bay with one large door opening. Box hangars provide more usable floor space per aircraft and are better suited to maintenance work, but they cost more per aircraft stored than a T-hangar row when multiple aircraft are involved.
Can a steel hangar be heated in a Canadian winter?
Yes. A steel hangar can be fully heated and insulated to any required standard. The building envelope specification must include a vapour barrier, batt or spray foam insulation in the walls and roof, and an insulated door system. Radiant tube heaters suspended from the roof structure are a common and efficient choice for hangar heating because they warm the aircraft and floor directly without heating large volumes of air that escape every time the door opens. The insulation specification should be coordinated with the HVAC designer.
How long does it take to build a steel hangar in Canada?
The total timeline from initial design to occupancy depends on permit approval duration, steel fabrication lead time, site preparation complexity, and erection crew scheduling. As a general orientation, permit approval alone can take several weeks to several months depending on the municipality and whether airport authority review is required. Steel fabrication lead times vary with market conditions. Owners who begin the design and permit process well in advance of their target occupancy date are better positioned to manage the schedule. No specific timeline guarantee can be made without a confirmed project scope.
What foundation type is standard for a plane hangar?
Most Canadian hangars are built on a reinforced concrete slab-on-grade with perimeter footings extending below the local frost depth. The slab thickness and reinforcement specification depend on the anticipated aircraft weight, fuel truck loads, and any jack point requirements. In areas with poor bearing soil, a thickened edge or grade beam may be required. Permafrost regions require specialist geotechnical input. For a full overview of foundation options for steel buildings, see the Steel Building Foundation Types guide.
Are there specific Transport Canada requirements for hangar construction?
Transport Canada’s Canadian Aviation Regulations (CARs) address maintenance environment standards for aircraft maintenance organizations (AMOs), which include requirements for hangar facilities used for licensed maintenance work. For private storage hangars not used for licensed maintenance, the primary regulatory framework is the National Building Code of Canada and the applicable provincial building code, plus any airport authority design standards. Owners planning to conduct licensed maintenance should consult the CARs directly and engage Transport Canada early in the design process. This guide does not constitute regulatory advice.
What door type is most common for Canadian general aviation hangars?
Hydraulic bifold doors and hydraulic bottom-rolling doors are popular for their speed and ease of operation, particularly in cold weather where manual sliding doors can freeze or become difficult to move. Bi-fold doors fold upward and are well suited to sites with limited apron space in front of the building. Sliding doors remain common for smaller hangars because of their lower initial cost and mechanical simplicity. The best choice depends on the door opening width, available apron space, climate, and budget. The Hangar Door Types guide provides a detailed comparison of all major systems.
Can I expand a steel hangar after it is built?
Steel hangars can often be expanded longitudinally (adding bays to the end of the building) more easily than they can be widened, because widening typically requires replacing the primary frames. Expansion potential should be discussed with the supplier at the design stage so that the end wall framing and foundation are detailed to accommodate a future addition. Attempting to expand a hangar that was not designed for it is significantly more complex and costly.
How do I get a quote for a plane hangar in Canada?
The most efficient starting point is to prepare a brief that includes the aircraft type and dimensions (wingspan, height, length), the intended use (storage, maintenance, or both), the site location and address, the required eave height, the preferred door type, and whether heating is required. With this information, a steel building supplier can produce a preliminary layout and budget estimate. Titan Steel Buildings works with owners across Canada on hangar projects of all sizes; the request a quote page is the starting point for a project conversation.
