I will design staircase structural plans stringer framing landing and stair details
About this Gig
Designing a safe, code-compliant staircase requires precise structural load calculations, exact stringer sizing, and compliant riser-tread geometry. Incorrect stringer cuts, undersized landings, or improper post supports cause structural bounce, code violations, or instant permit rejection.
As a civil and structural engineer, I design robust, permit-ready staircase structural plans for residential and commercial spacescovering straight, L-shaped, U-shaped, spiral, and floating staircases in wood, steel, or concrete.
What You Get
- Stringer & Tread Design: LVL, dimensional lumber, or steel channel stringers sized for live loads and deflection limits.
- Landing & Post Sizing: Frame sizing, column supports, and load path verification to existing foundations.
- Code Geometry Verification: IRC/IBC compliant rise, run, headroom clearance, and tread depth calculations.
- Permit CAD Drawings: Complete framing layouts, stringer cut details, handrail/guardrail anchorage, and connection hardware.
- Engineering Report: Formatted calculation PDF ready for city permit approval and builders.

FAQ
Q: What information do I need to provide to get started?
A: Total floor-to-floor height, available horizontal run space, stair type (straight, L-shape, U-shape), material preference (wood, steel, concrete), and photos or architectural plans of the opening.
Q: Will these drawings pass local building permit inspections?
A: Yes. Plans adhere to International Residential Code (IRC) and International Building Code (IBC) standards for riser height, tread depth, headroom clearance, and structural framing.
Q: Do you design both wood and steel stringers?
A: Yes. I design traditional cut/solid wood stringers, engineered lumber (LVL), steel channel C-shapes, mono-stringers, and floating steel stair systems.
Q: Can you include intermediate landing framing details?
A: Absolutely. Landings are calculated for live load transfers and include joist sizing, post callouts, and attachment hardware details.
