What NYC Business Owners Say
About Alliance
"We needed a full office buildout in Midtown on a tight deadline — 10 weeks, no exceptions. Alliance delivered in nine. They knew every DOB inspector by name. Best commercial contractor we've worked with in 20 years in New York."
"Opening a restaurant in Williamsburg is no joke — DOH requirements, exhaust specs, ConEd hookup. Alliance handled every piece of it. Our location passed every inspection first try and opened on time."
"We gutted and rebuilt our medical office in Flushing. The crew was professional, respectful of neighbors, and handled the DOB filing end-to-end. When something came up mid-project, they told us right away. No games."
FAQs
Frequently Asked Questions About
Commercial Construction in NYC
How much does commercial construction cost in New York City?
Commercial construction costs in NYC typically range from $150 to $500+ per square foot. Office fit-outs in Manhattan average $200–$350/sq ft; retail buildouts run $150–$300/sq ft; ground-up commercial builds start around $250–$500+/sq ft. Outer boroughs like Brooklyn, Queens, The Bronx, and Staten Island tend to be more cost-effective for ground-up development. Local Law 97 compliance upgrades, DOB Special Inspection requirements, and union labor considerations all affect the final number. Alliance provides free, detailed itemized estimates for every project.
Do I need a permit for commercial construction in NYC?
Yes — virtually all commercial construction work in NYC requires permits from the NYC Department of Buildings (DOB). This includes new construction, tenant fit-outs, alteration work (Type 1 and Type 2), demolition, and specialty work covering electrical, plumbing, HVAC, and fire suppression systems. Unpermitted work can result in stop-work orders, DOB violations, fines, and serious complications when you sell or re-lease the property. Alliance handles the entire DOB permit process for all of our NYC commercial projects.
How long does commercial construction take in NYC?
Timelines depend on project type. A standard office fit-out in NYC typically takes 8–16 weeks from permit approval. A commercial gut renovation runs 12–20 weeks. Ground-up commercial construction in NYC usually takes 12–24+ months, heavily influenced by DOB plan review times, foundation complexity, and site access. NYC’s urban density adds logistical variables — street closure permits, noise ordinances in residential neighborhoods, limited staging space — that our team plans around proactively on every project.
Are you licensed to do commercial construction in New York City?
Absolutely. Alliance General Construction Corp is fully licensed by the NYC Department of Buildings as a General Contractor, carries comprehensive general liability insurance, and maintains full workers’ compensation coverage as required by New York State law. All licensed trades on our projects — electricians, plumbers, HVAC contractors — carry their own NYC trade licenses. We provide certificates of insurance and licensing before any contract is signed.
What types of commercial construction does Alliance handle in NYC?
We handle a full range: office buildouts and tenant fit-outs, retail storefront construction, restaurant and food service buildouts, medical and dental facility construction, ground-up commercial buildings, commercial gut renovations, mixed-use and multi-family development, warehouse and industrial construction, and hotel and hospitality renovations. All services are available across Manhattan, Brooklyn, Queens, The Bronx, and Staten Island.
Do you work in all five boroughs of New York City?
Yes. Alliance General Construction Corp actively works across all five NYC boroughs — Manhattan, Brooklyn, Queens, The Bronx, and Staten Island. We know the borough-specific DOB offices, local subcontractor networks, neighborhood logistics, and zoning nuances for each area. We also serve adjacent areas including Long Island City, Astoria, and parts of Nassau County.
What is the difference between commercial and residential construction in NYC?
Commercial construction covers buildings used for business purposes — offices, retail stores, restaurants, hotels, medical facilities, warehouses, and mixed-use developments. In NYC specifically, commercial buildings are governed by different sections of the NYC Building Code, require different DOB permits, often mandate more rigorous fire suppression and egress requirements, and may involve FDNY approvals in addition to DOB. Commercial projects typically require larger crews, more complex MEP coordination, and often union labor agreements depending on project size.
How do I choose the right commercial construction company in NYC?
Look for: a valid NYC DOB General Contractor license, verified insurance certificates, a demonstrable portfolio of completed commercial projects specifically in New York City, knowledge of NYC zoning and building codes, transparent itemized pricing, and real references from NYC business owners. Also verify that the contractor has direct experience in your specific project type — office buildouts, restaurant construction, and medical facilities each have unique requirements. At Alliance, we welcome you to review our credentials and speak with past clients before signing anything.
Does Alliance handle Local Law 97 compliance in commercial construction?
Yes. Local Law 97 sets greenhouse gas emission caps for most NYC buildings over 25,000 sq ft. For new commercial construction and major renovations, this means planning around energy-efficient HVAC systems, improved building envelopes, LED lighting, and — increasingly — electrification of mechanical systems. Alliance factors Local Law 97 compliance into the planning stage of every qualifying NYC commercial project so you’re not hit with fines after the fact.

Built For New York
Alliance General Construction Corp —
A Commercial Builder That Knows NYC
New York City is not like anywhere else. The buildings are tighter, the codes are stricter, the timelines are shorter, and the expectations — from landlords, tenants, community boards, the DOB, and the FDNY — are higher than anywhere in the country.
You don’t hire a commercial contractor here the way you would in Phoenix or Charlotte. You hire someone who has built in these streets, dealt with these agencies, and worked with these trades — year after year, project after project, borough after borough.
That’s Alliance General Construction Corp. We’ve done office build-outs in glass towers in Hudson Yards. We’ve renovated restaurants on Court Street in Carroll Gardens and storefronts on Fordham Road in The Bronx. We understand that building in DUMBO has a different rhythm than building in Midtown — and we plan for every variable before it becomes your problem.
When you work with Alliance, you get a team that lives here, works here, and picks up the phone when you call. That’s the Alliance difference — and it’s why New York businesses keep coming back to us.
