Every day your commercial space is under construction is a day your business is disrupted. Multi-Construction Co. has been delivering commercial renovations across New York City since 1989 — offices, retail spaces, mixed-use interiors, and tenant buildouts — with a planning-first process specifically designed to protect your timeline, your budget, and your ability to keep operating. Licensed, full-service, and accountable from planning through completion.
"It is more than a passion project. It is more than a creative vision realized. It is Multi."
Every discipline below is managed directly by our team and sequenced around one priority: keeping your project on schedule without compromising the quality or compliance of the result.
01
Commercial layouts are planned around occupancy, circulation, egress, and operational workflow — not aesthetic preference alone. Whether it is an open office, a client-facing retail environment, or a mixed-use space, layout decisions are made with code requirements and daily business function as the primary constraints.
02
Design decisions are developed in parallel with construction planning — not before it. Finishes, materials, and spatial concepts are resolved against structural reality, lead times, and installation requirements so that what is designed can be built on schedule.
03
Commercial environments demand materials specified for durability, maintenance, and performance under high-frequency use. Selections are evaluated against lifecycle cost and maintenance requirements — not residential durability standards applied to a commercial context.
04
Mechanical, electrical, and plumbing systems are coordinated as part of the layout process. Commercial electrical loads, HVAC zoning, plumbing access, and data infrastructure requirements are mapped before walls are built — not resolved around them after the fact.
05
Compliance is not a review step at the end of design. ADA clearances, egress widths, occupancy loads, and sprinkler requirements are integrated into layout and construction planning from the first decision. This is the only approach that prevents compliance-driven redesign during construction.
06
Commercial permit submissions in New York City are more complex than residential filings. Occupancy classification, egress documentation, and engineer of record coordination are managed as part of our standard scope — not subcontracted or deferred to the owner.
07
For leased commercial spaces, renovation scope is developed in alignment with lease obligations, landlord consent requirements, and restoration clauses. Work is planned so it meets the tenant's operational needs without creating liability at the end of the lease term.
08
Commercial lighting is planned for task performance, brand environment, and energy compliance — not as a decorative layer applied after the space is designed. Fixture placement, electrical coordination, and control systems are resolved as part of the construction documents.
The construction process begins after every decision has been finalized.
Before scope, we review how the space needs to function — operationally, not just visually. Occupancy requirements, workflow patterns, lease constraints, and code obligations are identified before a single layout decision is made.
Layout, materials, MEP coordination, and compliance requirements are resolved together — not in sequence. Design is developed to a construction-ready level before execution begins, eliminating the gap between what is designed and what can be built.
Commercial DOB submissions, engineer coordination, and any landlord consent requirements are prepared and submitted before construction is scheduled. Approval timelines are built into the project plan — not treated as parallel processes that might delay construction.
Construction is carried out by the same team that planned it, on a schedule designed around your business operations. Phasing, access management, and noise and dust controls are planned in advance — not improvised on-site.
Thorough walkthrough before the project closes. All outstanding items resolved, permits closed with NYC DOB, and full documentation provided to you.
Commercial renovation in NYC covers an enormous range of space types, use cases, and building contexts. Our experience spans the full range of what New York City businesses occupy.
Single-floor renovations to full tenant improvement buildouts — planned around lease commencement dates, building management requirements, and teams that cannot stop working during construction.
Retail and hospitality generate no revenue while under construction. Opening dates are treated as fixed constraints, not targets. Timeline control is built into the plan from day one.
Work affecting shared MEP infrastructure, common areas, or building egress requires coordination with building management and neighboring tenants — managed before construction begins, not during it.
01
Renovation plans are developed with actual structural and building constraints in mind, which reduces revisions once construction is underway.
02
Planning, coordination, and construction are managed under one accountable team — eliminating the hand-offs that cause miscommunication and delay.
03
Decades of experience with apartments, co-ops, condos, and brownstones informs every decision we make.
04
Finishes are chosen for durability and long-term behavior—not short-term visual appeal.
05
Structured oversight and consistent communication keep every project controlled from start to finish.

We visit your premises, assess what’s actually possible inside your building, and give you a realistic scope, timeline, and cost before you commit to anything.
Have questions? We’ve answered some of the most common ones.
Phasing, access routes, and high-disruption work are scheduled before construction begins — planned around your business hours, not improvised around them.
It depends on scope and occupancy classification. Partition changes, electrical work, plumbing, and egress modifications typically require DOB filings with an architect or engineer of record. We manage this as part of our standard scope.
Most leases require landlord consent for anything beyond cosmetic changes — plan submissions, building management sign-off, and sometimes base building MEP coordination. We identify these obligations early so landlord approval runs in parallel with design, not after it.
Significant modifications can trigger path-of-travel upgrade requirements beyond the immediate renovation area. ADA obligations are identified before layout is finalized — not retrofitted after construction when corrections are most expensive.
