Why Choose Alternating Tread Stairs?
Traditional stairs aren’t always practical—especially in homes or spaces where every square foot counts. That’s where alternating tread stairs shine.
Unlike bulky staircases or steep ship ladders, alternating tread stairs:
- Provide greater tread depth per footstep for comfortable climbing
- Maintain a compact footprint, perfect for tight or awkward layouts
- Offer a forward-facing descent, unlike ladders that require backward navigation
- Comply with building codes for many residential and commercial applications
- Enhance access to lofts, attics, mezzanines, or secondary stories without expensive renovations

These stairs solve a major homeowner pain point: how to get full access to upper levels or storage areas without needing extensive remodeling or sacrificing usable floor space.
Who Benefits Most from Alternating Tread Stairs?
Alternating tread stairs are ideal for homeowners and property managers with limited floor space, but the advantages go far beyond just dimensions.
This solution is perfect for:
- Homeowners adding lofts, attics, or split-level storage
- Urban dwellings in Brooklyn or Queens with narrow footprints
- Contractors seeking code-compliant, space-saving designs
- Apartment buildings or duplexes needing compact egress options
- DIYers or renovators working on basement or mechanical access
If you’ve ever felt restricted by your current staircase—or wished you had a better way to access that bonus space—alternating tread stairs could be exactly what your home needs.
What Is the Point of Alternating Tread Stairs?
Alternating tread stairs are all about making the most of small spaces. The “alternating” design removes half the tread on each step in a staggered pattern, giving each foot its own extra-deep platform. This allows users to:
- Climb more naturally than a ladder
- Maintain balance and comfort despite a steep angle
- Reduce the staircase’s overall footprint
For properties where every inch matters, alternating tread stairs are the perfect balance of form and function—especially when installed by a team like Gibraltar with 40+ years of trusted remodeling experience.
Are Alternating Tread Stairs Up to Code?
Yes, alternating tread stairs are legal and up to code—when used in the correct applications and installed properly.
According to OSHA section 1910.25, alternating tread stairs are acceptable for areas where space constraints make traditional stairs impractical. At Gibraltar Home Improvements, we ensure your installation meets all local and state regulations in New York, including Nassau County and NYC-specific codes.
We do the legwork so you don’t have to worry about compliance.
Alternating Tread Stairs vs. Ship Ladders: What’s the Difference?
While both alternating tread stairs and ship ladders are space-saving stair solutions, the differences are crucial when it comes to safety and ease of use:
- Alternating Tread Stairs: Designed for face-forward descent, with alternating steps providing solid footing on both ascent and descent. More comfortable and safer for everyday use.
- Ship Ladders: Steeper with shallow treads—require users to descend backward like on a traditional ladder. Best for infrequent access or utility spaces.

For homeowners who want daily access to tight upper floors without the awkwardness of a ladder,
alternating tread stairs are the superior choice.
Long-Term Benefits of Installing Alternating Tread Stairs
Investing in alternating tread stairs gives you more than just a functional solution today — it pays off in convenience and usability for years to come.
After installation, you’ll enjoy:
- Improved access to areas that were previously hard to reach
- Enhanced safety for both kids and adults (with proper railings and code-compliance)
- Increased usable space for home offices, storage, or sleeping lofts
- Better resale value by showcasing smart design improvements

And with Gibraltar’s proven craftsmanship, you can trust that your new staircase will stand the test of time.

FAQs About Alternating Tread Stairs
1. Are alternating tread stairs comfortable to use?
Yes! Despite their compact design, alternating tread stairs are engineered for comfort and safety. Each foot has its own step, and the deeper treads make climbing or descending feel much more natural than a traditional ladder or ship stair.
2. Can alternating tread stairs be used in residential homes?
Absolutely. In fact, alternating tread stairs are becoming increasingly popular in urban homes, lofts, tiny houses, and remodeled attics. They’re especially useful in homes across Queens and Brooklyn where floor space is at a premium.
3. How much space do I need for alternating tread stairs?
One of the biggest benefits of alternating tread stairs is their minimal footprint. They generally require half the horizontal space of a traditional staircase, making them ideal for tight hallways, attic accesses, and utility areas.
4. How long does it take to install alternating tread stairs?
Most installations can be completed within a single day, depending on the materials and site conditions. Gibraltar’s expert team ensures a smooth process, from consultation to cleanup.
5. Can I customize the look of my alternating tread stairs?
Yes, Gibraltar offers multiple customization options including wood species, stain or paint colors, railing styles, and tread finishes. We ensure your stairs not only fit your space, but also enhance your home’s aesthetic.
