How To Build Outdoor Railing For Stairs

Stair rails are important for safety and support, but they can also be a stylish addition for the exterior of your home. If you’re adding new railings to your porch or deck, consider the height and length of the steps in order to determine how much material you’ll need. Then, cut wood posts to size and position them along the stairs according to building code regulations in your area. You can attach these posts directly to the stair stringers by measuring out an appropriate distance between each post and drilling holes through the stringer. After securing these base pieces with screws, add balusters along each riser support post before attaching a handrail along the top of all railing sections. With some simple tools and careful measurement, you can easily build outdoor railing for stairs on your own

Check building code regulations in your area.

When building an exterior stairway railing, be sure to check your local building codes before beginning. Check with the local fire department as well. You don’t want to build a railing that’s not up to code and then get fined when you start using it. You can also check with the local building inspector, who will give you a list of guidelines for what materials are acceptable in your area. They should also be able to tell you whether or not they want you to set up temporary railings while they approve plans for permanent ones.

The next step is talking with your local building authority—this may be separate from other agencies listed above but generally falls under the jurisdiction of city hall or county offices. They’ll guide you through checking about permits and inspections needed before starting construction on new outdoor structures like railings at stairs or decks that require safety measures like handrails in compliance with state laws concerning safety precautions (such as those stated in OSHA’s Construction Standard 1910). All these regulations need careful attention so that no one gets hurt during construction

Measure the width of the stairs, and draw a line on the wall so that you know where to attach the rails.

Measure from side to side across how far apart your railing will be. Draw a line down for each piece of your railing system, making sure that all measurements are even across any changes in height or length.

Use a circular saw to cut the material for the rail posts and baserails to size.

Use a circular saw to cut the material for the rail posts and baserails to size. A circular saw can be used to make straight cuts, but you will need a miter saw if you want angled cuts.

Use a power drill with an appropriate bit to make holes for screws. It is best to start on one end of your post, make all of your holes, then go back and fill them in with wood filler or caulk as needed before moving on to another post until all are completed.

Finally, use a level (if necessary) and clamp it against the side or end face of each piece before making any final adjustments for perfect verticality between each piece when set into place later on in this project!

Assemble one section at a time.

  • Attach the balusters to the riser support posts.
  • Attach the handrail to the stair railing, using lag screws or bolts and washers for strength as well as aesthetics
  • Attach the stair railing using a 2-inch deck screw through each rail slot into each corresponding post (two per post). If you’re using pressure-treated lumber for these supports, we recommend pre-drilling holes for this purpose before driving in any screws—they can split easily if not treated with care

Attach balusters along each riser support post.

Attaching the balusters is an easy step if you plan to use screws. Make sure to drill pilot holes for the screws first, and then use a screwdriver or drill to install them. Be careful not to over-tighten your screws, as this can cause the wood on your deck railings to split.

The easiest way to attach each riser support post is in two steps: First, measure from the top of one baluster down to its bottom end; this distance should be equal with the height of each riser plus 1/2 inch (1.27 cm). Then measure from either side of each baluster down toward its bottom end; these measurements should also equal with the width of each riser plus 1/2 inch (1.27 cm). If they don’t match up correctly, try adjusting them until they do—you may have made a mistake when installing your posts

Finish by attaching the handrails to the stair railing using screws.

You’re almost done! Now it’s time to attach your handrails. You’ll need to do this on both sides of each stair. The process is similar for all four types of railing:

  • Attach the handrail to the top of the top rail using screws and wood glue, as shown in [Figure 3]. Make sure you use long enough screws so that they go through at least 1/2″ in depth into the beam below or into a joist above if there is no beam below. You may have to remove some material from one side of your stairway frame so that your baseboard remains flush with it when installed on stairs that don’t have baserails (like ours).
  • Attach another piece at mid-level, connecting it with metal brackets just as we did with our deck railing posts back when we built our deck patio cover project earlier this year! This piece needs to be secured tightly enough so that little kids don’t pull them down while playing around this area; however, make sure not too tightly because then no one can get through easily either
  • Repeat step 2 again at bottom level – this ensures safety but also aesthetic appeal by providing visual interest in addition 🙂 If there wasn’t much space between posts where we installed our sliding gate door hardware before then now would be good time remove any remaining pieces left over from previous steps until only clean wood surface remains – sounds pretty easy though

Follow these steps to build a staircase railing for an outdoor or indoor stairs.

When you’re building an outdoor or indoor staircase railing, there are a few things to keep in mind. First, check local building codes to find out what the regulations are for railings. Also measure the width of your stairs and make sure that it’s wide enough for you to comfortably walk down with a hand rail on each side (most codes require at least 36 inches). You’ll also want to know how tall your stairs are so that you can plan out where the posts should go.

To figure this out, place one end of a tape measure or yardstick against one stair riser and use it as a straight edge against which you can draw lines across both risers and treads. Then mark off “X” marks where each post will go using pencil (or pen if desired). Make sure that these marks line up perfectly with each other before cutting any wood pieces

With this done, cut all necessary wood pieces using power tools like saws or drills equipped with circular blades/bits that have diameters equal/larger than widths between adjacent steps; this includes two posts per flight plus one additional baserail for every two flights (for example: if there are five flights total then cut six total rails including two end pieces).


These steps will help you build a sturdy and safe rail for your stairs. Make sure to follow building code regulations in your area, and consult with a professional if this project seems difficult or overwhelming. This is especially important if there are children or the elderly in your home.
