Building your own deck stairs might seem complicated, merely it doesn't accept to be! First, have conscientious measurements then you know exactly how many stairs you lot'll need to build. Then, frame out your deck and either purchase or build stringers, which are the function of the stairs that the treads and risers volition attach to. Finally, add the risers, then the treads—then just sit back and savour your outdoor space!

1. 1

   Bank check your local building codes regarding deck stairs. Before you begin purchasing materials and building your deck stairs, y'all need to become online, call your local regime, or contact a edifice inspector to brand certain yous're post-obit your local building codes. Edifice codes can vary, so you need to exist certain y'all're following your local codes or you lot could face a fine and exist forced to remove your deck stairs.^[one]

   • Many local governments list their building codes online.
   • Note that "riser acme" is defined equally the height from the top of i tread to the top of the next.
   • Stairs with more than ane step will probably also be required to include a handrail on both sides of the stairs. Open stairs, and the deck they serve, rising over thirty inches may besides demand guards on any open sides above the signal thirty inches loftier.^[2]

   Common Building Codes for Deck Stairs

   Stair treads: 36 inches (91 cm) broad and x inches (25 cm) deep
   Stair risers: seven.75 inches (19.seven cm) or less in acme
   Stringers: No notches (saw-toothed or stair-shaped cuts) deeper than half the width of the board, or the stringer volition be too weak

2. 2

   Cheque if you lot tin use pre-cutting stringers. Handyman suggests "stopping by a home centre or builders' supply store, which both sell pre-cutting stringers that are cut to standard dimensions. Using these is the best option unless you need the stairway to be steeper because there is non plenty space on the ground."

   • Measure the approximate height of the stairway you will build and the maximum infinite you can employ on the footing.
   • Check the pre-cutting stringers at the shop and measure their height and length. If they are longer than y'all need, you can cut them to size.
   • To cut a stringer to size, cut it so the bottom step is not equally high as the others. It can be much less loftier.

   Imagine a 40-degree gradient to find the landing zone of your stairs. The first thing you need to practice is notice where your stairs volition end, or where the landing spot will be. Movie a line running from the edge of your deck downward to the ground at a xl-degree angle. Place a tape mensurate on the basis where you recollect the stairs will end. It does not have to be measured precisely.^[three]

   • The twoscore-degree slope should kickoff the lesser of the support axle of the deck because this is where the stringers volition be fastened.

4. four

   Rest a straight board on the deck and make it level over the landing spot. Handyman Walter Brant advises "laying a long, directly lath on the deck, extending to directly higher up where the lesser of the stairs will exist (the landing spot). So, set a large level on the board to bank check that it is level." Brant also suggests to "level the board with shims if it slopes upwardly toward the landing spot. If the lath slopes downward, still level it with shims simply also measure from the ground to the board to come across how much this raised the end in a higher place the landing spot."

   • Write downwardly the measurements and so you can calculate the materials later.

5. five

   Split up the total ascent past 7 to find the number of 7 in (xviii cm) steps. Take the measurement y'all fabricated of the total rise, divide information technology by 7, and round the number to find the total number of stairs you'll need for your deck. Round this number up or down to the closest whole number to find the number of steps.^[four]

   • For case, if your total ascension was threescore inches (150 cm), then split up that number past seven to become eight.57. Circular that number up to get ix, and utilize 9 steps.
   • Write down this number to use in your calculations.

6. 6

   Find the rise of each pace by dividing the total ascent by the number of steps. The rise, or height, of each step tin exist calculated by dividing the total rise by the guess number of stairs—this will tell you how alpine each pace volition be.^[5] Co-ordinate to handyman Walter Brant, "Typical building codes require that stair risers should be no taller than 7.75 inches (19.7 cm). This is the top of each notch in the riser."

   • For example, if your total rise is 60 inches (150 cm) and your approximate number of steps is 9, divide 60 inches (150 cm) by ix to get 6.67 inches (16.nine cm) per stride.

7. seven

   Use tread boards that are at least 10 inches (25 cm) wide (deep). The treads boards create the office of the stair that you step on. According to many building codes, the stair treads should be at to the lowest degree 36 inches (91 cm) long (width of stairs) x inches (25 cm) deep.^[6]

   • The number of steps you calculated is the number of treads that you'll demand.

8. 8

   Find the length of the staircase by calculating the length of the stringers. Stringers are boards that have sawtoothed or stair-shaped notches cut into them and run diagonally along the length of the stairs to support them. To detect their length, add the foursquare of the run, or tread, and the foursquare of the ascent. So take that number, find the square root, and multiply information technology by the number of steps to find the actual length of the stringers you'll need.

   • For example, if your tread is 10 inches (25 cm), foursquare 10 past multiplying the number by itself, which gives you 100. If your rise is 7 inches (18 cm), foursquare that number by multiplying information technology by itself to get 49. Add 100 to 49 to become 149, then find the square root of 149, which is 12.206. Multiply that past the number of steps that you lot have to detect the total length of your stringers.

1. 1

   Cut custom stringers out of 2 in (5.ane cm) by 12 in (30 cm) boards. The stringers are what y'all'll attach your treads and risers to, and it's often difficult or impossible to notice pre-fabricated stringers that will fit your deck stairs. Yous'll need to cutting your own.^[7]

   • Most building codes stipulate that the stair stringers tin't have notches (saw-toothed or stair-shaped cuts) that are deeper than half the width of the board, or the stringer will be too weak.

2. 2

   Use a framing square to mark a sawtoothed blueprint as cutting guidelines. Set your framing square to the tiptop of the riser and width of the stair tread and employ a carpenter'south pencil to trace forth the edges of the framing square to class a sawtooth pattern of steps onto a 2 in (v.1 cm) by 12 in (30 cm) board. Lay the foursquare on the board and mark the lines, and so slide the square downward and marshal it with the previous mark before calculation the next ones.^[8]

   • Draw all of your cuttings lines onto the wood commencement, then check and recheck your measurements before you make whatsoever cuts.^[9]
   • The sawtooth or stair-shaped pattern should match the rise and tread measurements.

3. 3

   Cut the notches into the board using a circular saw. Let the bract come to full speed before yous cut the woods and cut the saw-molar notches out by post-obit the guidelines you lot marked. Don't cut all the style through the guidelines.^[10]

   • Be careful when operating a round saw. Habiliment safe goggles to foreclose sawdust from entering your eyes.

4. 4

   Finish the notch cuts with a handsaw. The circular saw volition cut most of the notch out, only y'all'll need to apply a handsaw to finish up the cuts without sawing beyond the cut lines. Fit the handsaw into the cut lines and use a back and forth motion to finish the cuts.^[11]

   • Accept care not to cut past the guidelines you lot marked or it could weaken the stringers.

5. 5

   Repeat the process to cut some other stringer. You lot demand at least two stringers to support your deck stairs, then use the same measurements and marking a 2 in (5.1 cm) by 12 in (30 cm) board to be cut. Use the circular saw to cut the notches and cease the cuts with a hand saw to separate another stringer from the board. It should be the verbal same measurements and cuts equally your first stringer.^[12]

   • Use the start stringer you cut equally a template for the side by side two.^[13]
   • If you're edifice the stairs on a surface that isn't level, your stringers may all iii need to exist slightly different lengths. Offset by cut the shortest one, so make the other two slightly longer on the bottom. Avoid using shims to adjust the stringers—they could fall out.^[xiv]
   • Measure, mark and cut with precision; the limit for differences between tread depths or riser heights is 3/16 per stair and 3/8 total for a flight of stairs.^[fifteen]

1. 1

   Screw each stringer to the bottom of the deck frame with a drill. Utilise Fifty-brackets and 3 in (vii.six cm) deck screws to attach the stringers to your deck. Place the height of the stringer against the bottom of the frame of the deck and screw an L-subclass on each side of the stringer to connect it to the deck.^[sixteen]

   • After you lot've attached the commencement stringer, connect the second stringer to the deck by following the same procedure.
   • Use 6 in (15 cm)-long corner braces on the two inside corners—wait for the ones labeled "braces for stringers," equally they're heavier steel than well-nigh braces.
   • For actress forcefulness, spiral several three ¹⁄_two  in (eight.9 cm) framing and decking screws diagonally through the stinger into the deck.^[17]

2. 2

   Cut the risers to the length of the top of the stringer. Set up a riser confronting the edges of the stringers facing out and use a ruler and pencil to mark cut guidelines where the riser needs to be trimmed to fit. Use a circular saw to trim the riser, cutting forth the guidelines until you cut through the whole board. Repeat the process until all of the risers have been cut to size.^[xviii]

   • Apply the kickoff riser that you cut to make your guidelines on the rest of the boards so you lot take a compatible length.

3. 3

   Adhere the risers with iii in (7.six cm) deck screws. Identify the risers against the edges of the stringers facing out from the staircase. Use a drill to bulldoze the 3 in (seven.six cm) deck screws through the risers and into the edge of stringers where they connect until all of the spiral is in the woods.^[19]

   • Use at least two deck screws to firmly secure the riser to the stringer.
   • Don't drill too far into the wood or it could fissure.

4. iv

   Trim the treads and drill them onto the stringers. Once you've fastened the risers, take your 1.five in (three.8 cm) by 10 in (25 cm) tread boards and cutting them to 36 inches (91 cm) in length. Then, lay them across the stringers facing up. Use iii in (7.6 cm) deck screws to attach the treads to the stringers by drilling through the tread boards and into the edges of the stringers where they connect.^[twenty]

   • Use at least 2 deck screws to adhere the tread boards.

   Alert: Make certain none of the screws are sticking out of the wood or someone could pace on information technology.

5. 5

   Add whatsoever necessary handrails and guards and call the local officials for any necessary inspection of your completed stairs.

Article Summary X

To build deck stairs, you'll need a framing square, drill, deck screws, a circular saw, and wooden boards. Earlier you lot buy your materials, you'll need to measure the superlative of your deck, then divide this past the height you desire each stair riser to exist. Check your local edifice codes, which will often tell you how loftier each step needs to be. To fasten your stair treads and risers together, you lot'll need to make a stringer for each side. You tin can use the framing square and circular saw to cut right-angled triangles in a sawtoothed pattern in each stringer. When you spiral the stringers to your deck, you can easily spiral the treads and risers into each prepare of right-angle triangles. For more than tips, including how to work out how much wood you need for your deck stairs, read on!
