Make sure the joist hangers are rated for outdoor exposure and are compatible with pressure-treated lumber. Use hot-dipped galvanized nails or exterior-grade structural screws to assemble the members. Look for this information on a plastic tag stapled to the end of the board. Select your materialsįor the in-ground posts and the framing, use pressure-treated lumber suitable for ground contact. It’s easier to fix mistakes made on paper than it is relocate posts set in concrete. Other considerations include whether to place the posts on the inside or outside or the ramp’s framing, what railing style to, use and how to transition from the ramp to ground level. Tight spaces and/or high decks might require switchbacks (zig-zags) in the ramp and/or a ramp that wraps around the deck (photo). You’ll have to decide whether to build the ramp over the existing stairs or to attach it to the deck elsewhere. ![]() Then see if you can create similar designs that fit the space you have. Search online and in your neighborhood for wheelchair ramp designs that you like. Homeowner associations will likely also have specific requirements and prohibitions. Gather all the information you can from building authorities and your local building code because the requirements will influence your design and material choices. That could require you to present a scaled plan and possibly await a site visit before starting. In most cases, you’ll need a building permit to add a wheelchair ramp to your deck. A ramp longer than 30’ or a change in ramp direction requires a 60” x 60” landing measured from handrail to handrail. Using the ADA-approved 1:12 ratio, the number of inches of rise equals the number of feet of run. This is the vertical distance from the ground where the ramp starts to the deck edge where it ends. To calculate the length of your ramp, measure the rise. In most cases, the existing deck provides plenty of room at the entry, but make sure the transition from the deck to the entry door’s threshold is no more than 3/8”. ADA compliance also requires similar areas at ground level and in front of the entry door. Larger handrails would require a wider ramp deck.ĭepending on your design, 60” x 60” landings may be required along the ramp’s path. In practice, this means the minimum width of the ramp deck will be 42 inches, because each handrail-one on each side 34 to 38 inches above the ramp surface-of 1.5 inches must be at least 1.5 inches away from any surface. Ramps must be at least 36 inches wide at the narrowest point, typically from handrail to handrail. These include the minimum width of the ramp, its maximum slope, and the handrail height. There are important dimensions to be aware of when building a wheelchair ramp that will meet ADA guidelines (link). If you’ve done some DIY building projects, you probably have most of the tools needed to build a wheelchair ramp.īuilding a DIY Wheelchair Ramp Estimate the size of the ramp Anchor bolts (Such as Grip Rite 1/2 in.Standoff post base (Such as Simpson ABA ZMAX or ABU ZMAX ($10 or $20).Use this list of materials as a starting point to create your own. For instance, you may want to match the look of your deck boards and handrails or add lighting to the ramp. The type and quantity of materials required to build a wheelchair ramp depends on the size and design of it. ![]() Required Materials & Tools for Building a Ramp Follow these basic steps to plan and build an ADA-compliant wheelchair ramp that attaches securely to your deck. ![]()
