What Is the Difference Between a Hangar and a Canopy?

Hangars

Hangars are large buildings used for storage, equipment housing, production, and other industrial or agricultural purposes. They may have arched, straight-wall, polygonal, or fabric-covered designs.

Hangars are often constructed using prefabricated components, allowing relatively rapid assembly. Depending on the construction method, they may be framed or frameless.

A framed hangar has a load-bearing structure, usually made of steel, to which the roof and wall cladding are attached. Fabric-covered hangars use a supporting frame with a PVC fabric covering.

Frameless arched hangars commonly use specially profiled metal panels that form the structural shell. Other hangar designs may incorporate different materials, including timber, depending on the project.

Canopies

A canopy is a roofed structure supported by columns, posts, or other structural elements. Depending on its design and purpose, it may also be attached to a building or partially enclosed by walls.

Its main purpose is to provide overhead protection while retaining an open or partly open space.

The Main Difference

Because both structures can have roofs and walls, the distinction may initially seem unclear.

A hangar is generally an enclosed building with walls around its perimeter and one or more large openings or doors for vehicles, machinery, or goods.

A canopy generally has one or more open sides. It may have partial wall enclosure, but its defining feature is the open arrangement rather than a fixed maximum number of walls.

The main practical difference is therefore the degree of enclosure: a hangar provides an enclosed internal space, while a canopy provides overhead shelter with greater exposure to the surrounding environment.

Permanent and Temporary Structures

A canopy should not automatically be classified as a temporary structure simply because it has open sides. Likewise, the name “hangar” does not by itself determine a building’s legal status.

In Ukraine, classification depends on the applicable legislation and the characteristics of the particular structure.

Factors that may need to be assessed include:

• whether the structure can be relocated without significant damage, loss of value, or a change in its intended purpose;
• whether it can be dismantled and reassembled;
• the type of foundations and its connection to the ground;
• connections to permanent utility networks;
• the design, permitting, and property documentation.

These factors must be considered in context rather than treated as a universal checklist.

Ukrainian legislation defines temporary structures used for business activities by specific criteria, including lightweight construction, temporary installation, and the absence of foundations. Whether a particular canopy falls within that category requires an assessment of its actual design and use.

Can a Canopy Be Considered a House?

An open-sided canopy does not ordinarily provide the enclosed living accommodation associated with a residential building. However, its legal classification cannot be determined solely by its name or appearance.

If a structure is enclosed, converted, or adapted for another use, the relevant design, construction, and registration requirements must be assessed separately.

Canopies for Hay Storage

Canopies can be useful for storing hay because the roof provides protection from direct rainfall while the open sides allow ventilation.

However, a canopy does not automatically keep hay dry. Its effectiveness depends on the roof dimensions, exposure to wind-driven rain, ground conditions, drainage, and storage arrangement.
