Commercial Construction NYC — Office, Retail & Restaurant Build-Outs
Licensed commercial contractors serving Brooklyn, Manhattan, and Queens since 2004. Office build-outs, retail fit-outs, restaurant construction — DOB permits, expediting, and Certificate of Occupancy handled in-house, under one fixed-price contract.
A Commercial Contractor Built for NYC Business Timelines
Dream Build Construction has delivered commercial construction across Brooklyn, Manhattan, and Queens since 2004 — office build-outs, retail fit-outs, restaurant construction, and full tenant improvements. As a licensed general contractor, we manage every trade under a single fixed-price contract: demolition, framing, mechanical, electrical, plumbing, sprinkler, and finish work, with one project manager accountable for the entire schedule.
Commercial work in New York City is a different discipline from residential renovation. Landlord work letters, building rules, DOB filings, expediting, ADA upgrades, fire alarm sign-offs, and Certificate of Occupancy timelines all determine when you can actually open your doors — and every week of delay is rent paid on a space that isn't earning. Our team maps the full approval path before demolition starts, so the schedule you sign is the schedule we build to.
Whether you're a retailer fitting out a Williamsburg storefront, a restaurant group building a code-compliant commercial kitchen, or a medical practice opening an office in Manhattan, we deliver move-in-ready space — on budget, fully inspected, and legal to occupy from day one.

How Our Commercial Build-Out Process Works
Walkthrough & Fixed-Price Proposal
We survey your space, review the landlord work letter and lease requirements, and deliver a detailed line-item proposal — so you know the real number before you commit.
DOB Permits & Expediting
Our team prepares plans, files all NYC DOB permits, and coordinates professional expediters to compress approval timelines — mechanical, plumbing, electrical, and sprinkler included.
Construction & Compliance
Daily supervision across all trades, with sprinkler, fire alarm, and ADA compliance built into the schedule from day one — not discovered at inspection.
Inspections & Certificate of Occupancy
We close out every city inspection and secure your Certificate of Occupancy or Letter of Completion, handing over a space that's legal to occupy and ready for business.
NYC Permits, Expediting & Sign-Offs — Handled In-House
Most commercial project delays in NYC aren't caused by construction — they're caused by approvals. We manage the entire regulatory path in-house so your opening date doesn't depend on a stalled application sitting in a city queue.
DOB Filings & Expediting
Plan preparation, NYC Department of Buildings filings, and professional expediters who walk applications through the system instead of waiting in the queue.
Sprinkler & Fire Systems
Sprinkler modifications, fire alarm tie-ins, and FDNY-related sign-offs coordinated with licensed engineers from the first design meeting — never as an afterthought.
ADA Compliance
Accessible entrances, restrooms, counters, and path-of-travel upgrades engineered into the design — required for nearly every commercial space in New York City.
Certificate of Occupancy
Final inspections, agency sign-offs, and the Certificate of Occupancy or Letter of Completion that lets you legally open your doors for business.

Frequently Asked Questions About Commercial Construction in NYC
Commercial construction in NYC typically runs $100–$200 per square foot for standard office build-outs, $150–$300 per square foot for retail fit-outs, and $250–$450+ per square foot for restaurants and commercial kitchens due to ventilation, plumbing, and gas requirements.

A standard office build-out of 2,000–5,000 sq ft typically takes 8–12 weeks of construction after permits are issued. Retail fit-outs run 6–10 weeks, while restaurant construction takes 12–20 weeks because of kitchen equipment, ventilation, and health department requirements. NYC DOB permitting adds 4–8 weeks up front — we file early and use professional expediters to compress the overall schedule.
Yes. Dream Build Construction manages the entire NYC approval process in-house — DOB permit filings, architectural plans, expediting, sprinkler and fire alarm sign-offs, ADA compliance documentation, and every required inspection through the final Certificate of Occupancy or Letter of Completion. You never have to chase city agencies yourself.
