NYC DOB Permit Engineering for Floating Stairs

At New York Floating Stairs , permit coordination is not an afterthought. It's built into every floating stair project from day one. The NYC DOB requires stamped engineering drawings, connection schedules, and load calculations for any structural stair system — and producing that documentation takes real engineering expertise, not just a general contractor filling out forms.

We prepare the full permit package in-house. That means our structural engineer reviews existing wall conditions, calculates cantilever loads and anchor forces, and produces drawings that satisfy DOB plan examiners without repeated revision cycles.

Pre-war buildings add complexity. Masonry bearing walls, old timber framing, and irregular structural bays don't match the assumptions in modern engineering templates. We field-verify conditions before drawing anything, then design to what's actually there.

For co-op and condo board submissions, we provide engineering summaries and plan sets formatted for review committees that don't have engineering backgrounds. Clear documentation speeds up board approval and protects you from unnecessary delays.

Our permit workflow integrates directly with our fabrication schedule. Once DOB approval comes through, parts are ready to build. You're not waiting for an outside engineer to finish drawings while your timeline slips.
