I BUILT MY DAD A GARAGE | Building your own detached garage.

Introduction

This tutorial outlines the step-by-step process of building a detached garage, inspired by a recent project where a father and son team constructed a 24x22-foot garage. You will learn how to frame walls, install windows, and finish the garage while managing costs effectively.

Step 1: Lay Out the Foundation

• Measure and Mark: Start by measuring the area where the garage will stand. Use the diagonal method to ensure the layout is perfectly square.
• Chalk Lines: Snap chalk lines to outline the footprint of the garage on the ground.
• Prepare Materials: Gather all necessary materials, including wood for framing, OSB sheets, and tools like a circular saw and level.

Step 2: Frame the Walls

• Top and Bottom Plates: Lay out the top and bottom plates of your wall and mark the stud locations at 16 inches on center.
• Assemble Wall Sections: Construct the wall sections on the ground by placing studs between the top and bottom plates.
• Install Window Frames: Cut out a rough opening for the window, following the package specifications. Use a header made of two 2x6s with a strip of OSB in between.

Step 3: Raise the Walls

• Stand the Walls: Use a front-loader tractor to lift the framed walls into position. Ensure they are squared and secure them to the base.
• Repeat for Remaining Walls: Frame and lift the remaining walls using the same method. Ensure all walls are aligned correctly.

Step 4: Frame the Roof

• Cut Ridge Beam Supports: Create supports for the ridge beam that will hold the roof structure.
• Mark Rafters: Measure and mark locations for rafters on the ridge beam, maintaining the 16-inch spacing.
• Cut Rafters: Use a rafter calculator or app for precise measurements. Cut the rafters from 2x6 lumber.

Step 5: Install the Rafters

• Hang Rafters: Secure the rafters to the top wall plates. Use rafter ties to ensure they are stable and aligned.
• Check for Plumb: Use a string line to check that the walls remain plumb as you install the rafters.

Step 6: Install OSB Sheathing

• Sheet the Roof and Walls: Install 4x8 OSB sheets horizontally on the walls and roof, nailing every 6-8 inches along the studs.
• Cut Openings: Once the sheathing is in place, cut out openings for windows and doors as needed.

Step 7: Hire Out Additional Trades

• Identify Trades Needed: Hire professionals for roofing, siding, and window installation to complete the project efficiently.
• Cost Management: Source materials yourself to save on costs. For example, using Hardy plank for siding can enhance durability.

Conclusion

Building a detached garage can be a rewarding DIY project that significantly lowers costs. By framing the structure yourself, you can save considerable money while learning valuable skills. The total investment for the entire garage build in this project was approximately $12,700, encompassing materials and labor.
