You can have a nice car but you need somewhere nice to stick it. That’s where garages come in handy. Whether it’s to shelter the vehicles from the cold or the heat it doesn’t matter, the sun will pick a temperature. Your car wants to come inside after a long day just like you do. If you do not have a garage but have a lot of space, there is a way that you can give your car its new home.

Things to consider

When building a garage, you have to consider the size. There are housing requirements and state codes that you must consider. Be sure to get your plans approved by the city. You could end up losing a lot of money if the city shuts down your garage construction. You have to consider the height, size, and number of structures on your lot.

After you figure out the size and shape of your garage, check to make sure where you can place it. The best option is to receive a survey of your property and then mark it off with your specifications. Once you have your plans together, ask your neighbors (as a courtesy) if they have any problems or concerns with your garage. If your plans have trouble getting approved, you can apply for variances. This way if any other inspectors come by, you can show the paperwork saying that you are approved to be out of regulation.

  1. The first step in building is planning your layout. Lumber is expensive so do not try to build as you go. Use your chalk line to map everything out on the ground. Have everything drawn out so you can be sure of how many 2×4 boards you will need. Also, have extras because accidents happen.
  1. Next step is to install bottom plates. Building garages have to start at the bottom. A strong foundation is key. Use the hammer drill to put holes in your wood and concrete and use the impact driver to drive 3″ Tapcon screw into the holes. Keep this going for every 16 inches until complete.
  1. The top plates depend on which way you are running your bottom plates in relations to the joists above. If perpendicular, the top plates should be placed where the joists intersect. If parallel plates, attach 2″ x 4″ blocking boards between the joists.
  1. When done, go around and mark all your stud placements. They are usually every 16 inches so use your tape measure for exact points. Uneven studs can make for uneven weight distribution and that can be disastrous later.
  1. Once everything has been marked off, you can begin installing your studs. Place your 2×4 in between the top and bottom plates until they are snug. Use your leveler to make sure they are perfectly plumb. If they aren’t plumb, it can have the same problem as uneven spacing.
  1. Finally, install your blocking. Place 2×4 boards between the studs and secure them with more 3” nails. It’s ok if the boards are slightly staggered to keep the nails colliding.

Frequently Asked Questions

  1. What is the cheapest way to finish a garage wall? Metal knee walls are the cheapest way to finish a garage wall. They have high durability and are easy to clean. Once properly installed, they are going to last years. If there is a random case of roughness with the metal knee walls and it suffers damage, you can just unscrew that section and replace it.
  1. What should I line my garage walls with? Lining your garage depends on your intended use for it. Fiberglass insulation will involve some extra steps to prevent wear and tear from weather. Coated foam sheets are easier to install and do not require extra steps due to the way they are manufactured.
