▸ COMMERCIAL — DESIGN TO C.O.
We deal with
the building department.
Design, construction, permits, and your final Certificate of Occupancy — one crew, one contract, no hand-offs. You run your business; we get the space legal and built.
▸ DRAFTING
Design and drawings that anticipate the plan examiner, not just the client.
▸ PERMITS
We file, we chase, we answer objections. You never stand in line at the building department.
▸ FRAMING
The build itself, sequenced and supervised by the people who priced it.
▸ FINISHES
The part your customers will actually see, held to the drawings.
▸ C.O. ISSUED
The Certificate of Occupancy in your hand. The project is not done until this is.
ONE CONTRACT — DESIGN THROUGH CERTIFICATE OF OCCUPANCY
What we build
Spaces that open on time.
Office Build-outs
Renovations and fit-outs that get your team working in the space, with the inspections behind you instead of hanging over you.
Retail Setups
Storefronts and retail interiors where every week before opening day is rent paid for nothing — so the schedule is the design constraint, not an afterthought.
Design & Planning
Layouts and drawings done with buildability and the code in mind from the first sketch — because we're the ones who have to build them and get them signed off.
Why us
Before Westchester, our founder spent decades in NYC commercial construction — the most demanding permitting environment in the country.
That's where "turnkey" stops being a marketing word and becomes a survival skill. Guy DiNapoli built Essential Builders with his sons in 2020 to bring that skill to local businesses: 65+ years of combined experience, and a family name on every job.

Address and what you want it to become — that's enough to start. We'll walk it with you.
