Checklist for preparing to buy a prefabricated garage

In addition to selecting a suitable garage type, usage, structural requirements, legal conditions, and costs must be considered at an early stage. This structured checklist helps you to systematically review all aspects relevant to your decision and avoid planning errors.

Define the intended use and requirements

First, you should determine what the garage will be used for. Possible usage scenarios include:

• Storage for one or more vehicles
• Additional storage space for bicycles, tools, or garden equipment
• Combination of parking and storage space

Depending on your needs, a single garage may be sufficient, or a larger solution—for example, with additional depth or width—may be more appropriate. Future changes such as a change of vehicle, electric mobility, or increasing space requirements should also be taken into account in the planning.

In addition, the guide section offers further information on usage concepts.

Check dimensions, interior dimensions, and access

For everyday usability, it is not only the exterior dimensions that are decisive, but above all the usable interior dimensions. Wall thicknesses, supports, or fixtures reduce the available space. The following should also be checked:

• Door width and door height
• Sufficient maneuvering space in front of the garage
• Access width and slope on the property

A realistic measurement check prevents later restrictions when driving in and out.

Clarify the building site and foundation at an early stage

A stable foundation is a prerequisite for the long-term stability of a prefabricated garage. Depending on the soil conditions and garage type, different foundation solutions are possible, such as point, strip, or slab foundations. It is important to clarify at an early stage:

• which type of foundation is required
• whether the foundation will be constructed on site
• or is part of the manufacturer's scope of services

Check building regulations and permits

Whether a building permit is required depends on state building regulations, garage size, and location. Even garages that do not require a permit are often subject to regulations regarding:

• Clearance areas
• Boundary construction
• Maximum floor space or height

Early consultation with the relevant building authority prevents delays in the project.

Select the roof shape and features

The roof shape not only affects the appearance, but also drainage, space utilization, and building regulations. Common variants are:

• Flat roof
• Gable roof
• Monopitch roof

Additional features such as side doors, windows, ventilation systems, or electric gates increase user comfort.

Prepare for delivery and assembly

Prefabricated garages are usually delivered by truck and placed on the foundation with a crane. To ensure that everything runs smoothly, the following should be checked in advance:

• Access for transport vehicles
• Necessary maneuvering and crane areas
• Possible obstacles such as trees, pipes, or narrow access roads

Early coordination with the supplier reduces installation delays.

Calculate costs realistically

In addition to the pure garage price, all project-related costs should be taken into account, including:

• Foundation and earthworks
• Permit fees
• Special equipment and accessories

Very low offers should be critically examined, as savings often come at the expense of quality, equipment, or service. A transparent cost comparison increases planning reliability.

Systematic preparation is the basis for a prefabricated garage that is suitable and functional in the long term. A structured review of usage, technology, legal aspects, and costs facilitates the decision-making process and reduces risks during the course of the project.
