Can you work while our business stays open?

Yes — most of our commercial clients stay operational. We phase the work, schedule noisy or disruptive tasks off-hours, and maintain dust barriers and safe egress throughout.

How fast can you turn over a commercial space?

It depends on scope and permits, but a typical office or retail buildout runs 6 to 12 weeks of construction. We give you a real schedule with milestones, not a guess.

Do you work with property managers on multi-unit buildings?

Yes. We do apartment renovations, unit turnovers, common-area upgrades, and building-envelope work for landlords and management companies across Brooklyn, Manhattan, Queens, and Staten Island.

Commercial Construction in Brooklyn, Manhattan, Queens & Staten Island

Commercial construction runs on a different clock than residential. Every week of delay is lost revenue, and every surprise is a budget problem. M&M GC Contractor Inc has been building out commercial spaces across Brooklyn, Manhattan, Queens, and Staten Island since 2001 — offices, retail stores, restaurants, medical offices, and multi-family common areas and unit renovations.

We self-perform the core trades with our own crews — demolition, framing, drywall, electrical, plumbing, and finishes — which means tighter schedules, fewer coordination failures, and one company accountable for the result.

Buildouts that keep your business moving

We plan commercial work around your operations: phased construction, off-hours and weekend work, dust and noise control, and protection for areas that stay open. For restaurants and retail, we coordinate equipment deliveries and health-department requirements into the schedule. For offices, we handle the full interior package — demising walls, glass fronts, pantry and restroom buildouts, lighting, and data rough-ins coordinated with your IT vendor.

Landlords and property managers use us for unit turnovers and capital improvements too: apartment renovations, lobby and hallway upgrades, and facade and waterproofing work that protects the asset.

Permits, filings, and sign-offs without the runaround

Commercial work in NYC means DOB permits, and often Place of Assembly, sidewalk, or Landmarks filings depending on the space. We prepare and file permit applications, manage inspections, and close out with the certificates and sign-offs your lease or lender requires. We've done this across all three boroughs and know how to keep filings from becoming the critical path.

We also carry the insurance and documentation commercial landlords and building managers require, and we provide it before work starts — not after someone asks twice.

Why homeowners and businesses choose M&M

Licensed & insured general contractor operating in New York City since 2001 — over two decades of finished jobs, not promises.
Big jobs only. We do full renovations, kitchens, bathrooms, brownstones, waterproofing, roofing, commercial and exterior work. We don't do handyman calls, which means your project gets a real crew and real project management.
In-house crews for demolition, framing, drywall, flooring, electrical and plumbing — fewer subcontractors, fewer delays, one accountable team.
NYC building know-how: DOB permits, co-op and condo board packages, Landmarks Preservation Commission approvals, occupied-building logistics — we've done it hundreds of times.
Direct line to the owner. Call (917) 251-9318 and you talk to the people actually running your job.

How your project runs, start to finish

Consultation & site visit. We walk the space, listen to what you want, and flag anything structural, code-related, or permit-related up front.
Detailed scope & estimate. You get a clear written scope and a firm price — no allowances hiding the real number, no surprise change orders later.
Construction. Our in-house crews handle demolition through final finishes. The site stays clean, protected, and on schedule, with one point of contact throughout.
Final walkthrough. We go through every detail together before sign-off. If something isn't right, we fix it. That's the "built on trust since 2001" part.
