How to Attach Ledger Board to House
To attach a ledger board to a house for deck installation, follow these steps:
1.
Begin by laying out the position of the ledger board and marking the locations of joists, guardrail posts, stairs, and any other accessories to ensure they do not interfere with each other.
2.
Measure and determine the length of the front rim joist and ledger board.
The front rim joist should be the same length as the installed beam, while the ledger board should be 3 inches shorter than the front rim joist.
3.
Overlap the side rim joists, which are 1 ½ inches wide, onto the ledger board.
Connect them through the joist into the ledger board.
Additionally, connect the side rim joist with the front rim joist by overlapping it.
By following these steps, you can successfully attach a ledger board to your house for deck installation.

Did You Know?
1. The practice of attaching a ledger board to a house, commonly used in deck construction, dates back to ancient Rome, where they were called “plutei.” These were large, ornamental wooden panels used to decorate the exterior of buildings.
2. While ledger boards are typically constructed using wood, some modern construction techniques make use of composite materials like fiberglass-reinforced polymers (FRPs). These materials offer increased durability and resistance to water damage and insect infestation.
3. Back in the 1920s, attaching ledger boards to houses was a much less common practice. Instead, builders often relied on strategically placed columns to support elevated structures like balconies and porches.
4. The attachment of ledger boards to a house can significantly impact its structural integrity. When done incorrectly, it can lead to water infiltration, rot, and even collapse. Proper installation and regular inspection are crucial for long-term safety and maintenance.
5. In recent years, the development of specialized fasteners like ledgerlok screws has revolutionized the process of attaching ledger boards to houses. These screws are designed to provide strong and secure connections, eliminating the need for traditional lag bolts or through-bolts.
Layout Of The Ledger
Before attaching the ledger board to your house for deck installation, it is crucial to plan and layout the ledger properly. Start by marking the positions of the joists, guardrail posts, stairs, and any other accessories on your deck plan. Ensuring that these elements do not interfere with each other is essential for a structurally sound and aesthetically pleasing deck.
Taking the time to carefully plan the layout will help you avoid running into any issues during the construction process. By visually mapping out the various components of your deck, you will have a clear blueprint to follow, allowing for a smoother installation experience.
Determine Length Of Front Rim Joist And Ledger Board
After finalizing the layout, it is time to measure and determine the length of the front rim joist and ledger board. To do this, place the front rim joist against the house where the ledger board will be attached. The length of the front rim joist should match the desired overall length of your deck. This will act as the main support beam for the deck structure.
Next, measure the ledger board ensuring it is 3 inches shorter than the front rim joist. This gap allows for proper drainage and prevents any water accumulation between the board and the house. Accurate measurements at this stage are crucial to ensure the deck is properly aligned and securely attached to the house.

Overlap The Side Rim Joists
To ensure stability and structural integrity for your deck, it is crucial to overlap the side rim joists with the ledger board. These side rim joists, typically 1 ½ inches wide, will connect through the joist into the ledger board. The overlap provides additional support and helps distribute the weight of the deck evenly.
To achieve this, align the side rim joist with the front rim joist and overlap it onto the ledger board. This connection not only strengthens the deck but also creates a smooth and seamless transition between the rim and ledger boards.
Install Beam And Front Rim Joist
Before attaching the ledger board, it is crucial to install the beam and front rim joist. This beam will be the primary support structure for your deck and must be securely fastened to the side rim joists and the ledger board.
Start by placing the front rim joist onto the side rim joists, ensuring a tight joint. Use appropriate structural fasteners, such as structural screws or nails, to secure the front rim joist to the side rim joists, creating a solid connection.
Once the front rim joist is in place, install the beam by attaching it to the front rim joist using joist hangers or metal brackets. Ensure proper spacing and alignment to evenly distribute the weight and provide maximum support for the deck structure.
Attach Ledger Board To House
With the front rim joist, beam, and side rim joists securely in place, it is time to attach the ledger board to the house. This step requires precision and attention to detail, as the ledger board will bear a significant portion of the deck’s weight.
Position the ledger board against the house, making sure it is level and aligned with the marked layout you created earlier. Start by drilling pilot holes into the ledger, ensuring they are properly spaced and aligned with the fastener’s requirements.
Insert appropriate lag screws or structural screws through the pilot holes and into the house’s framing members. This will provide a solid and secure attachment between the ledger board and the house. Make sure to tighten the screws firmly, but not excessively, to avoid damaging the ledger board or the house’s structure.
Secure Side Rim Joists To Ledger Board
To complete the attachment of the ledger board, it is crucial to secure the side rim joists to the ledger board. This step ensures that the entire deck structure is properly connected and stable.
Using joist hangers or metal brackets, attach the side rim joists to the ledger board. This connection will provide additional support and prevent any movement or shifting of the deck structure over time. Ensure proper spacing, alignment, and secure fastening for each side rim joist, creating a robust and reliable attachment to the ledger board.
By following these steps, you can successfully attach a ledger board to your house for deck installation. It is imperative to adhere to local building codes and guidelines, and if necessary, consult with a professional contractor or engineer to ensure the safety and durability of your deck. With proper planning, accurate measurements, and secure fastening techniques, you can create a beautiful and long-lasting deck that enhances your outdoor living space.
Frequently Asked Questions
What screws to attach ledger board to house?
When it comes to attaching a ledger board to a house, the IRC recommends using either hex-head 1/2-inch hot-dipped galvanized bolts or 1/2-inch lag screws with standard cut washers. These fasteners are deemed suitable for securely connecting deck ledgers to the house. The hex-head bolts and lag screws offer reliable strength and durability, ensuring the ledger board remains firmly attached to the house throughout the life of the deck.
How do you attach a ledger to a wall?
To securely attach a ledger to a wall, start by drilling ½” pilot holes through the ledger board using a wood bit. Then, switch to a concrete bit and drill into the concrete wall. Once the holes are ready, carefully position the ledger board against the wall and insert two bolts at each end of the ledger. To ensure stability, hammer the sleeve anchor through the ledger board and into the concrete wall, firmly securing the ledger in place. With this method, you can confidently attach the ledger to the wall, creating a strong and durable structure.
Do you nail or screw a ledger board?
When attaching a ledger board, it is recommended to use screws rather than nails. While nails may bend when exposed to shear force, screws provide a more secure hold. I would suggest using SD screws, specifically 1-1/2″ for the ledger/rim and 2-1/2″ for the diagonal through the joist. This combination will ensure a sturdy and durable attachment for your ledger board.
How much weight can a ledger board hold?
A ledger board that is 10′ long is designed to bear a considerable amount of weight. Specifically, each foot of the ledger must be able to support a minimum load of 200 lbs. Therefore, the total weight that the ledger board can hold is 10 x 200 lbs = 2000 lbs. This sturdy support is crucial for providing stability and structural integrity to the project it is used in.
