Building a garage can be a significant investment for homeowners, offering both functionality and the potential to increase property value. Understanding the costs involved is essential for making informed decisions. This article will break down the average costs, factors influencing pricing, and tips for managing expenses effectively.
Average Cost to Build a Garage

The national average cost to build a garage is approximately $24,000. However, this figure can vary widely depending on several factors, including size, location, and the materials used. Detached garages generally cost less than attached garages, with basic kits starting around $7,250, while custom models can exceed $50,000.
Garage Cost Per Square Foot
Garage construction costs are typically measured by square footage. On average, building a garage costs between $35 and $70 per square foot. For example, a standard two-car garage could range from $30,000 to $45,000, depending on its size and features.

Single-Car Garage Cost
Single-car garages can vary significantly in price based on dimensions and materials. Here are a couple of examples:
• 12 by 24 feet: Approximately $15,000
• 14 by 28 feet: Around $20,400
These costs reflect basic construction without high-end features or finishes.
Two-Car Garage Cost
The size and design of a two-car garage also influence costs. The most significant factor is the type of parking arrangement:

• 24 by 30 feet (tandem): Around $31,200
The latter option saves space but may have higher costs for customization.

Attached Garage Cost
The average cost for an attached garage is about $26,000. However, prices can vary from $10,000 to $43,000 based on size and amenities. Since attached garages typically connect to existing plumbing and electrical lines, they may save on installation costs.
