Step 6 · Add Railings (Optional but Recommended)
If installing railings, you'll need to attach railing posts securely to the stringers or the porch frame. Posts should be at least 4x4 lumber and securely bolted. Then, attach the top rail and any intermediate rails, ensuring they are at a safe height (check local codes, typically 36-42 inches from the tread surface). Balusters or pickets are then installed between the rails, spaced according to code (usually no more than 4 inches apart).
