3 car 20×30 gable carport – Free DIY Plans

Ovidiu 0 GapDice RANDOM PLAN

This step by step diy project is about 3 car 20×30 gable carport plans. This is a 3 car shelter with a sturdy truss-based gable roof. This carport is sturdy and it features a roof with a 6:12 pitch. If you need a structure like this on your property, make sure you take a look over my instructions and diagrams. The base of the carport, outside post to outside post, is 20 ft by 30 ft. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.

*Make sure you read the local building codes before starting the project, so you get aware of the legal requirements and make the necessarily adjustments.

When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day. Premium Plans for this project available in the Shop.

Triple Carport Plans

Use 6×6 lumber for the posts. Use circular saw to make the cut-outs to the top of the posts. Set the circular saw to 1 1/2″ depth and make parallel cuts inside the marked areas. Use a hammer to remove the excess material. Smooth the surface with a chisel and sandpaper.

First, layout the posts for the 20×30 carport. Use batter boards and string to determine the location of the posts. Apply the 3-4-5 rule to every corner of the carport, so you make sure they are right angled. Make sure the diagonals are equal. Determining the location for the structure is essential, as you have to comply with the local building codes. Make sure the surface is level and remove the vegetation layer.

Setting the posts in concrete

Setting the posts in concrete

You can set the posts in concrete (about 3′ deep – make sure you read the local building codes for accurate information) or you can pour footing and use posts anchors. If you live in an area affected by hurricanes, it would be better to set the posts in concrete.

Use a post hole digger to make 16″ holes in diameter and 3′ deep. Pour a 2″ layer of concrete on the bottom of the holes so you level them. Fit the tube forms and then the anchors. Align the anchors one with another and make sure all footings are horizontal one to another, otherwise you will need to make adjustments to the height of the posts.

Use 2×12 lumber for the top support beams. Fit the support beams to the top of the posts, inside the notches. If everything was done properly till this step, the beams should be perfectly horizontal. Clamp the beams to the posts and drill pilot holes through both the beams and the posts. Insert 6″ carriage bolts with nuts and washers. Use 2 bolts for each joint.

Use 6×6 lumber for the braces. Make 45 degree cuts to both ends of the braces. Fit the braces to the structure, as shown in the diagram. Drill pilot holes and insert 5 1/2″ screws to lock the braces into place tightly. Use a spirit level to make sure the posts are plumb, before setting the braces with screws.
