At New York Floating Stairs , every custom floating stair engagement starts with a structural site assessment — not a catalog selection. We evaluate the existing wall assembly, floor-to-floor height, and load-bearing capacity before any design decisions are made.

NYC has specific requirements that don't apply elsewhere. DOB permit submissions for structural stair systems require stamped engineering drawings, connection details, and load calculations prepared by a licensed engineer. We handle that in-house. You don't need a separate structural engineer.

Pre-war buildings need special attention. Older masonry walls and timber framing have different load-bearing characteristics than modern construction. We identify what's actually behind the wall before we design an anchor strategy — not after installation reveals a problem.

Our fabrication is matched to field measurements. Steel stringers, tread brackets, and railing components are built to the actual dimensions of your space — not to standard sizes adjusted with shims. That precision shows in the finished product.

We work in Manhattan, Brooklyn, Queens, the Bronx, and into New Jersey. Whether you're renovating a West Village townhouse, converting a Dumbo loft, or upgrading a Jersey City condo, the structural standard doesn't change.

What's included in a custom floating stair project

A full-scope installation with our firm includes structural assessment, engineering documentation for DOB, design coordination, material selection guidance, fabrication, installation, and final inspection support. One contract. One point of contact. No subcontracted engineering.

How We Deliver a Custom NYC Floating Stair

Floating stair installation process in a New York City property
01
Site Assessment
We visit your property, inspect wall conditions, and measure floor-to-floor heights. For pre-war buildings, we verify framing and masonry before committing to an anchor strategy.
02
Structural Engineering & DOB Docs
Our engineer calculates load paths and prepares the stamped drawings and connection details required for NYC DOB submission.
03
Design & Material Selection
We review tread materials, finish options, and railing configurations. Wood species, glass, steel — all coordinated with your interior.
04
Precision Fabrication
Components are built to your field measurements. Steel stringers and tread assemblies are fabricated for exact fit-up — no shimming.
05
Installation & Inspection
Our team anchors, aligns, and finishes the system. We coordinate DOB inspection scheduling and resolve punch-list items before handoff.
Common questions

Frequently Asked Questions

Do floating stairs in NYC require a DOB permit? +
Yes. Any structural stair installation or replacement requires a permit from the NYC Department of Buildings. We handle the engineering documentation, plan coordination, and inspection scheduling as part of our standard scope.
Can floating stairs work in a pre-war building? +
Yes, but the approach is different. Pre-war masonry walls and older framing need to be evaluated before anchor design is finalized. We assess existing conditions in the field, then specify only the reinforcement required for a safe installation.
How long does a typical NYC floating stair project take? +
After the site assessment, DOB permit review typically takes a few weeks. Once approved, fabrication and installation usually runs one to two weeks depending on scope. We provide a milestone schedule before fabrication begins.
What tread materials do you install? +
White oak, walnut, maple, and other hardwoods are the most common choices. We also build glass tread systems and can coordinate composite or stone treads for the right application. We match material selection to your interior and building type.
Will my co-op board need to approve the project? +
Most co-op and condo buildings require board approval for structural work. We provide the engineering summaries, plan sets, and documentation packages boards typically request. We've done this before and can help you navigate the process.
