What we do
Additions we build
Every addition is custom to the lot and the house. These are the projects homeowners call us about most.
-
01
Rear & side additions
New rooms off the back or side of the house, tied into the existing foundation, roof line and floor levels.
-
02
Bump-outs
A few extra feet for a kitchen, bathroom or mudroom when a full addition is more than you need.
-
03
Second stories & add-a-levels
Building up when the lot leaves no room to build out — a common answer on tight Hudson County lots.
-
04
Primary suites
Bedroom, bathroom and closet planned together so plumbing, venting and HVAC are laid out once.
-
05
Kitchen & family-room extensions
More room where the household actually gathers, with the electric and plumbing to support it.
-
06
Garages & detached builds
Garage builds and conversions, detached studios and shops — framing, siding, roofing and bathrooms inside.
-
Free ballpark

Why Hoboken GC
One contractor, one schedule, one written scope
- The trades are ours. Plumbing, electric and HVAC run under the same schedule as framing and finishes. We have a Licensed Master HVACR (NJ Lic. #19HC00894700) and a licensed master plumber (NJ Lic. #36BI00667500) on staff.
- We pull the permits and meet the inspectors. Building, electrical and plumbing permits under New Jersey’s Uniform Construction Code are filed by us as your licensed contractor.
- We tell you what moves the price before it moves. Foundation and soil conditions, panel upgrades and matching the existing roof, siding and windows are called out in writing, not discovered on a change order.
- We build next to people who live there. Floor protection, dust walls, material access and daily cleanup are planned before demo — including on narrow Hoboken and Jersey City blocks with shared walls.
- You can check us. NJ HIC #13VH13409900, fully insured, certificates of insurance on request. See license & insurance.

Straight answers
Questions homeowners ask us
Can you give me a price from my plans?
Yes — a ballpark range. Upload your plans or photos and we reply within 48 hours with a range, the assumptions behind it and what it excludes, or with the questions we need answered first. The price you sign is set in a written estimate after we walk the property.
Do you pull the permits for an addition?
Yes. As your licensed contractor we file the building, electrical and plumbing permits the addition needs under New Jersey’s Uniform Construction Code, schedule the inspections and meet the inspectors.
What if my addition needs zoning approval?
Setbacks, lot coverage and height decide what can be built on your lot. If a plan pushes past what the zone allows, it may need a variance before any building permit is issued. We flag that early so you do not spend money on finishes for a plan the town will not approve.
Can we live in the house during the addition?
Often, yes. We plan protection, dust control and material access before demo starts. If a kitchen or bathroom has to go offline, we tell you when and for how long, in writing, before work starts.
How long does a home addition take?
It depends on the size, the zoning and permit path, and the season — approvals and inspections often drive the schedule more than the labor does. You get a realistic timeline in writing with the estimate, and we tell you the day something slips.
Do you build additions outside Hoboken?
Yes. Hoboken GC LLC serves all of North Jersey, including Jersey City, Weehawken, Union City, West New York, North Bergen, Secaucus, Hackensack and Parsippany-Troy Hills.
