Factors to consider when designing your 3-car garage

Now that you know the minimum dimensions for a 3-car garage, there are a few things you need to consider before finalizing your plans.

  • Types of Vehicles: Before building a 3-car garage, you must know the vehicles you will be storing in. Since the 3 car garages are spacious, you can choose to store SUVs, RVs, trucks, or even motorbikes.
  • Additional Storage: Do you need some extra storage around your 3-car garage? This is important because some families may need extra storage, especially for storing tools.
  • Activities: Many people also use their ample garage space for conducting various activities. Therefore, if you plan to learn some new techniques or have a small workshop for yourself, you may increase the space.
  • Building Codes and Regulations: According to the International Building Codes and Regulations 2018, the carports and garages will belong to “Group U”. As per this rule; the private garages shouldn’t be more than 1000 square feet. A building can have multiple private garages, each of which may be separated by a barrier as per Section 711. If you do not follow the rules, you will be subjected to paying double of your permit fee as the penalty fee. Therefore, you must know how big is a 3 car garage size and build one accordingly. Since there are no specific laws for three car garages in the US, the general laws for International Building Codes and Building Codes are to be followed.

Other Considerations for 3 Car Garage Size

There are a few other things to consider when determining the size of your 3-wheels garage.

The first thing you need to consider is how many cars you want to be able to park in your garage.

If you only have two, you can get away with a smaller garage, but if you have three or more, you’ll need a more oversized garage.

If you or someone in your family uses a wheelchair, you will need a larger garage to load or unload the wheelchair quickly.

You might also want to consider adding a ramp to your garage, so it’s easier to get the wheelchair in and out.

If you’re looking to add storage shelves to your garage, there are a few things to consider.

First, think about where you would like to place them. Second, decide what kind of shelving you would like. Would built-in shelving be a better option, or would free-standing shelves work better for your needs?

Finally, think about what items you’ll keep on the shelves. If you’re planning on storing heavy objects, choose sturdy shelving that can support the weight.

If you frequently make trips to the grocery store, you might want to consider adding an extra freezer or refrigerator to your garage.

This will allow you to keep extra food on hand, so you don’t have to make as many trips to the shop. To have a refrigerator in your garage, you need extra power outlets and insulation.

The average garage is not insulated, so you’ll need to add insulation to keep the refrigerator from working overtime and driving up your energy bill.

Also, you need more space for the refrigerator, so make sure to factor that into your overall garage size.

If you enjoy working on projects around the house, you might want to add a workbench to your garage.

A workbench will give you a place to store your tools and work on projects. You can either buy a pre-made workbench or build one yourself.

When deciding the size of your workbench, think about how much space you’ll need to store your tools and how much workspace you’ll need.

If you’re planning on working on large projects, you might want a larger workbench, so you have plenty of room to spread out.

So these are other things to consider when deciding on the size of your 3-car garage.

If you own an SUV or truck, you’ll need a 3-wheels garage at least 22′ deep so that you can open the doors fully without hitting the wall.

Most people have a pickup truck, full-size SUV, or minivan and prefer a 3-car garage that is 30′ deep so they can quickly move around inside.
