Stair Building Handbook

Every staircase carries an invisible contract: that whoever built it got the math right, cut the stringers true, and followed code closely enough that no one climbing it will ever think twice about their footing.

Most builders piece together stair knowledge in fragments - a technique from a mentor, a code number memorized from an inspector, a workaround found the hard way on a jobsite. Stair Building Handbook brings those fragments together into one comprehensive, code-aware reference for the full arc of the trade, from your first stringer layout to the winder calculation you'll need to double-check years from now.
Inside, you'll learn how to:

• Build the vocabulary and code framework (IRC and IBC) behind every stair decision
• Calculate rise, run, and stringer length, then lay out cut, housed, or mono stringers step by step
• Frame and build every configuration you'll meet on the job - straight runs, L- and U-shaped turns with landings or winders, spiral and curved staircases
• Install code-compliant handrails, guardrails, balusters, and newel posts that pass inspection the first time
• Handle exterior and deck stairs, from footings and drainage to weather-resistant materials
• Diagnose and repair common stair problems, and bring older staircases up to current code

Every calculation, code reference, and technique is explained from first principles, so you follow the logic instead of memorizing a formula - no prior stair-specific experience assumed, just basic carpentry know-how.
It's written for carpenters and contractors building stairs as part of broader framing work, finish carpenters formalizing their skills, apprentices in a notoriously math-intensive trade, remodelers working on stairs that no longer meet code, and serious do-it-yourself builders planning a custom staircase of their own. Where older stairbuilding references predate composite decking and current code cycles, this handbook reflects how stairs are actually designed, built, and inspected today.

Pick it up for your first stringer layout. Keep it on the shelf for the day, years from now, when you need to double-check a winder calculation.
