Deck Building Stairs in Medford, OR — Done Right the First Time

Proper deck building stairs are one of the most code-sensitive parts of any deck project — and one of the most commonly done wrong by DIYers and unlicensed contractors. At Medford Deck Building Pros, we design and build stairs that meet Oregon Residential Specialty Code, pass inspection, and hold up to years of use. Call (541) 500-0416 for a free estimate.

We build stairs for new deck installations and as standalone additions to existing decks throughout Medford and the Rogue Valley. Whether you need a simple two-step drop to the yard or a sweeping multi-flight staircase on a hillside property, we've built it.

Why Deck Stairs Fail — and How We Prevent It

Most stair failures come down to a few recurring problems:

Undersized or improperly set footings. Stair stringers need solid footings that go below the frost line — in Medford, that's typically 12–18 inches. Footings poured too shallow heave in winter and shift in spring, making stairs uneven and unsafe.

Inconsistent rise and run. Oregon code requires consistent riser height (max 7¾ inches) and tread depth (min 10 inches) throughout a stair run. Even a ¼-inch variation can cause a trip hazard. We measure and cut every stringer to spec.

Wrong material for the exposure. Stair treads take more wear and moisture than deck boards. We spec the right material — composite, pressure-treated, or hardwood — for the exposure level and traffic the stairs will see.

No handrail or non-compliant handrail. Oregon code requires a graspable handrail on any stair with four or more risers. We include compliant handrail systems in every stair build.

Types of Deck Stairs We Build

Straight-run stairs — The most common configuration, clean and efficient
L-shaped and switchback stairs — For elevated decks where a straight run would land in an awkward spot
Floating or open-riser stairs — Modern aesthetic, great for composite and hardwood treads
Wide ceremonial stairs — Full-width entry stairs that make a statement
Accessibility ramps — Low-slope ramp alternatives for ADA-friendly access, integrated into the deck design

Stair Materials

We match stair materials to the rest of the deck:

Composite treads (Trex, TimberTech) — Low maintenance, splinter-free, holds up to Southern Oregon's wet winters
Pressure-treated pine — Solid budget option, needs periodic sealing
Cedar — Natural look, naturally rot-resistant
Hardwood (Ipe, Tigerwood) — Premium option, extremely durable, beautiful grain

Permits and Inspections

Deck stairs in Medford are part of the deck building permit — they're inspected along with the framing and footings. We handle the permit application and schedule all required inspections. You don't have to deal with the City of Medford Building Department.

For standalone stair additions to existing permitted decks, we assess whether a separate permit is required and handle it if so.

Stair Pricing

Standalone deck stair projects in the Rogue Valley typically run $1,500–$5,000 depending on the number of flights, materials, and footing requirements. Stairs built as part of a new deck are included in the overall project estimate. Call (541) 500-0416 for a free on-site estimate.
