How Much Would It Cost To Build A Detached Garage? (2024)

When considering home improvements or additions, many homeowners contemplate the construction of a separate structure to house their vehicles, provide additional storage, or create a dedicated workspace. The cost of building such a structure can vary significantly based on numerous factors.

This article explores the various elements that influence the expense of constructing a standalone garage and provides insights into budgeting for this project.

Table of Contents

Size and Dimensions

The size of the detached garage is one of the most significant factors affecting its cost. Larger structures naturally require more materials and labor, resulting in higher expenses. A standard single-car detached garage typically measures around 12 feet by 20 feet, while a two-car garage might be approximately 20 feet by 20 feet. Larger dimensions or custom sizes will increase the new garage.

Materials

The choice of materials for the garage construction plays a crucial role in determining the final price. Common options include wood frame construction, concrete blocks, metal structures, and brick or stone exteriors. Each material has its advantages and associated costs. Wood frame construction is often the most economical choice, while brick or stone exteriors tend to be more expensive but offer enhanced durability and aesthetic appeal.

Foundation and Roofing

The foundation is a critical component of any average detached garage. Options range from a simple concrete slab to a crawl space or full basem*nt. A concrete slab is typically the most cost-effective choice, while a full basem*nt provides additional storage or living space but comes with a significantly higher price tag.

Roofing materials and styles impact both the appearance and cost of the garage. Asphalt shingles are generally the most affordable option, while metal roofing offers durability and energy efficiency. Premium materials like tile or slate provide high-end aesthetics but at a considerable cost increase.

Electrical and Plumbing

Installing electrical systems and plumbing can substantially increase the overall expense of building a detached garage. Basic lighting and outlets are often essential, but more advanced electrical systems for power tools or electric vehicle charging can add to the cost.

If plumbing for a sink or bathroom is desired, this will further increase expenses. The complexity of these systems and local building codes will influence the final cost.

Permits and Regulations

Obtaining the necessary permits and adhering to local building codes is essential when constructing a new detached garage. Permit fees and potential modifications to meet regulations should be factored into the budget. The total cost can vary significantly depending on the location and complexity of the project.

Labor Costs

Labor expenses can vary significantly based on location, complexity of the project, and the chosen contractor. Urban areas and regions with higher costs of living typically have higher labor rates. It’s important to obtain multiple quotes from reputable contractors to ensure a fair price for quality workmanship.

Additional Features

Customizations and additional features can quickly increase the cost of a detached garage. Insulation, windows, custom doors, workbenches, storage systems, and heating and cooling systems all add to the functionality and comfort of the space but also impact the overall budget. Homeowners should carefully consider which features are essential and which can be added later if budget constraints are a concern.

Cost Estimates

While it’s challenging to provide an exact figure without specific details, the general cost ranges for building a detached garage can be estimated based on size and features.

A basic single-car detached garage with minimal features might cost between USD$16,000 and USD$25,000. This estimate typically includes simple wood frame construction, a concrete slab foundation, basic electrical wiring, a standard garage door, and asphalt shingle roofing.

For a standard two-car detached garage, costs could range from USD$25,000 to USD$40,000. This usually covers larger dimensions, wood frame or concrete block construction, a concrete slab foundation, a basic electrical system, two standard garage doors, and asphalt shingle roofing.

Those seeking a high-end detached garage with additional features can expect costs to escalate quickly, potentially ranging from USD$40,000 to USD$100,000 or more. This premium option might include larger dimensions, high-quality materials like brick or stone exteriors, enhanced foundation options, premium roofing materials, advanced electrical systems, custom doors and windows, insulation, climate control, plumbing, and built-in storage solutions or workspaces.

Ways to Reduce Costs

For homeowners working with a tighter budget, several strategies can help reduce the overall cost of building a detached garage. Opting for standard sizes and simple designs can significantly lower expenses. Choosing cost-effective materials and limiting customizations and additional features can also keep costs down. Some homeowners may consider a prefabricated garage kit as a more affordable alternative to custom construction.

Conclusion

The decision to build a detached garage should align with the homeowner’s specific needs, budget constraints, and long-term property goals. With careful planning and informed decision-making, a detached garage can become a valuable and functional addition to any home.
