An open plan starts with a structural question. Before a wall is removed, the apartment, building, licensed professionals, and approval path all need to be understood together.
A useful starting point
01
A partition wall separates rooms without carrying the building’s load. A structural wall may carry floor, roof, or other loads into the structure below. A visual inspection alone cannot establish which condition is present; finishes can hide framing, utilities, and previous alterations.

A structural engineer’s assessment, building drawings or records where available, and the condition of the existing structure help establish what the wall is doing. Structural conclusions require a licensed professional’s analysis, not a contractor’s guess.

Wall removal can trigger DOB filing, and co-ops and condos may also require an alteration agreement and board review. We help coordinate alteration agreement requirements and DOB-related filings through licensed professionals when required. Final approvals remain with the building, board, or applicable agency.

Co-op boards and managing agents commonly ask for drawings, a protection plan, and notice before work begins. The building’s current documents and alteration agreement terms govern what is required.

Depending on the engineer’s design, reinforcement can involve steel beams or headers, reinforced framing, engineered connections, and post-work inspections. The construction scope follows the approved design; it is not selected from a generic rule of thumb.

Feasibility-first planning makes hidden conditions, professional inputs, building review, and sequencing questions visible before demolition. Early discovery can reduce avoidable change orders and help the project team make a more useful scope decision.

Possibly, if a structural engineer approves the design and the wall is properly reinforced, with the required building and agency approvals. Approval is project- and building-dependent; it is not routine.
A licensed professional must assess the structure, available records, and existing conditions. A contractor should not make that structural determination by guesswork.
Possibly, depending on the scope. A licensed design professional determines the applicable filing path, and the building or agency may have additional requirements.
That is building- and board-dependent. The alteration agreement and the building’s review process govern the request.
Planning a structural change?
Share the building, the wall location, and the scope you are considering. A clear first review helps identify which questions belong with the engineer, design team, and building.
