This step by step diy project is about 12×16 lean to patio cover plans. This lean to has a 2:12 pitch and it can be both used as a carport or as a patio cover. If you like a simplistic design, this project will help you get the job done and save tons of money. Premium Plans also available in the Shop. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.
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.

Building an attached carport – 12×16 DIY Plans
Laying-out
The first step of the project is to set the posts for the wooden attached carport. Use batter boards and string to layout the posts for the lean to attached patio cover.
Anchoring the posts of the anchor
You can set the posts in concrete or you can pour 3′ deep footings and use posts anchors. Considering this is a light outdoor project, you can set the posts to anchors. That is why, these plans are designed having that assumption in mind (concrete anchors).
Dig the holes and set the 14″ tube forms. Fill the tubes with concrete and set the post anchors. Make sure you let the concrete to dry out for a few day, before installing the posts into place. Use temporarily braces to secure the posts until you attach the plates.
Use a laser level / water level to make sure the top of the posts are at the same level.
Fitting-the-ledger-board
Next, we need to attach the ledger to the house. Make sure you set the 2×8 ledger directly into the framing structure with 4 1/2″ lag screws with washers (or longer, depending to the house structure). Use a spirit level to check if the ledger is horizontal. Drill pilot holes and insert the screws to lock it into place tightly (see your local codes for more info on how to secure the ledger).
Top-support-beam
We need 6×6 lumber for the support beam. Mark the cut lines to the beams and make parallels cuts inside the area. Remove the excess with a chisel and clean the edges.
Fitting-the-top-beam
Continue the project by attaching the support beam to the top of the posts. See the 12″ overhangs on the sides. Plumb the posts and make sure the beams are horizontal. Drill pilot holes through the beams and insert 8″ screws into the posts. Insert 2 screws for each joint.
Fitting-the-braces
Use 6×6 lumber for the braces. Make 45 degree cuts at both ends of the braces and then secure them into place with 5 1/2″ screws (at least 2 screws for joint).
Building the lean to roof
Rafters
Use 2×8 lumber for the rafters. Make a 10 degree cut to one end of the rafters. Mark the cut lines on the beams and then get the job done with a circular saw. Smooth the edges with sandpaper.
Fitting-the-rafters—lean-to-cover
Fit the rafters to the attached carport, every 24″ on center. Fit the rafters to the top of the ledgers using rafter hangers and 1 1/2″ structural screws. Use rafter ties and 1 1/2″ structural screws to lock the rafters to the support beams.
Fitting-the-roofing-sheets
Use 3/4″ plywood for the roof sheeting. Lay the sheets and align the edges flush. Leave no gaps between the sheets. Insert 1 5/8″ screws to lock the sheets into place tightly, every 8″ along the framing.
Front-roof-trims—front
Use 1×6 lumber for the roof trims. Align the edges flush and insert 2″ nails to lock them into place.
Side-roof-trims
Cut and fit the trims to the sides of the carport. See the 10 degree cut to one end.
Fitting-the-roofing
Cover the roof with tar paper, making sure the strips overlap at least 2″. Then install the asphalt shingles starting with the bottom of the roof. Read the manufacturer’s instructions, so you can install the roofing properly.
Install drip edges to the front and side edges. In addition, install a flashing at the intersection of the roof to the wall.
12×16 patio cover
Fill the holes with wood putty and let them dry out for a few hours. Smooth the surface with 100-220 grit sandpaper and remove the residues with a damp cloth.

You should take a look over my 24×24 garage plans and 16×24 garage plans, because you can easily add this carport to them. In this manner, you will have a garage with a side carport and shelter mare than one car.

This project can be built in less than one week and it can also be used as a patio cover. I recommend you to read the local building codes before starting the project, so you make sure you comply with the local building codes. See all my Premium Plans in the Shop.
If you build this carport attached to the double garage, you will have a nice shaded area that will be perfect for a car or for woodworking outside. If you want to get the Premium Plans, see the GET PDF PLANS button bellow.
