Cost Considerations for Garage Construction

When planning to build a garage, a key aspect to consider is the size, which largely depends on the types of vehicles you own and their dimensions. For instance, a standard passenger car is typically about 14 feet in length, while larger vehicles, such as full-size pickup trucks, SUVs, or minivans, can measure up to 24 feet long.

It’s crucial to factor in not just the size of your vehicles but also any additional features they might have, such as bull bars, wheelchair lifts, or rear-mounted bike carriers. To ensure ease of movement and comfort, it’s recommended to plan for an extra 4 to 5 feet of space around each vehicle, providing ample clearance and accessibility.

Attached vs. Detached Garage Building Costs

Another important consideration is deciding between an attached or detached garage. Building an attached garage is more cost-effective than constructing a detached one. However, the total expenses will vary depending on several factors. These include the level of interior finishing you desire, the necessity for driveway paving, and whether you plan to incorporate a living space above the garage. Each of these elements can significantly influence the overall cost, making it vital to consider your specific needs and preferences when planning your garage project.

WCG-Detached-garage-planview-2-car-garage-How much does it cost to build a two car garage in Portland Oregon?

Comparing Costs: Attached vs. Detached Garages

Cost of Attached Garages When it comes to attached garages, the average cost varies based on size. For a single-car garage, the price range typically falls between $79,579 and $148,500. If you’re looking at a two-car garage, the starting cost is around $106,100. For larger needs, such as a four-car garage, prices can ascend to approximately $225,750. Options for attached garages include a fully enclosed and finished space or a more basic carport-style structure with only a roof and no walls.

Cost of Detached Garages Detached garages, on the other hand, start at about $79,579. Most homeowners spend between $109,100 to $157,870 for these structures. The total cost can be influenced by various factors, including the garage size and additional features. If you opt to include an apartment or living space above the garage, this will necessitate extra costs for plumbing, HVAC, and electrical installations. Additionally, if you need a doorway leading into the house from the garage, this will also impact the overall expenses.

Cost and Return on Investment for a Garage with an Apartment

Constructing a garage with an apartment can be a significant investment, with costs varying depending on the project’s scope. For a garage that spans around 576 square feet and includes a fully finished apartment, the average expense ranges from $167,000 to $235,000This investment can be particularly advantageous if the apartment is designed as a rental unit atop a detached garage, potentially enhancing your return on investment (ROI).

It’s important to note that while the potential for higher ROI is present, the initial costs are also substantially greater. This increase in expenditure is due to the need for additional amenities such as electrical, plumbing, an HVAC system, and a new roof to ensure the space is fully functional and habitable. These elements are crucial in maximizing the comfort and appeal of the apartment, thereby increasing its rental value and long-term financial returns.

Garage Materials Cost Breakdown

Garage Foundation Cost

A garage foundation costs $2,700 to $6,900, depending on the size. A standard 24’ x 24’ (2-car) garage foundation costs about $5,158.

The cost of laying a foundation for a garage can vary significantly based on its size. Generally, you can expect to spend between $2,700 and $6,300 for this foundational aspect of garage construction. For a more specific example, the foundation for a standard-sized 24’ x 24’ two-car garage typically amounts to approximately $8,987.
