16×24 Lean to Patio Cover Plans

by Ovidiu


This step by step diy project is about 16×24 lean to patio cover plans. This lean to has a 1.5:12 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 – 16×24 DIY Plans



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 carport.

Anchoring the posts of the anchor

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.



Next, we need to attach the ledger to the house. Make sure you set the 2×10 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).



Continue the project by attaching the support beams 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.



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



Use 2×10 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.



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.



Fit the 1×4 purlins to the top of the patio cover. Place the purlins every 24″ on center and secure them to the rafters with 2 1/2″ screws. We need these purlins so we can install the metal roofing sheets.



Use 1×6 lumber for the roof trims. Align the edges flush and insert 2″ nails to lock them into place.



Cut and fit the trims to the sides of the carport. See the 7 degree cut to one end.



Cover the roof with metal roof sheets.

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.  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.

I need to know the measurement from the floor to the top portion of the house roof for the patio cover. I originally bought a 16×20 patio cover, but I now realize that I need a 16×24 patio cover instead.
