Garage Additions
Single, double, and three-car attached or detached garages — foundation, framing, garage doors, electrical, optional EV-charging circuit, and finished or unfinished interior. Optional living space, office, or storage above.
Attached & Detached Garage Additions
Bergen County homeowners add garages for vehicles, storage, workshop space, or to support living space above. We coordinate setbacks, footings, slab, framing, garage doors, electrical (including EV charger circuits), and any second-story accessory dwelling work.
- Single, double, and three-car configurations
- Attached or detached construction
- Concrete slab with proper drainage
- Insulated, weather-sealed garage doors
- Dedicated electrical with EV-charger capacity
- Optional bonus space, office, or ADU above
Serving Bergen County homeowners across Englewood, Tenafly, Fort Lee, Ridgewood, Paramus, Teaneck, Hackensack, Closter, Fair Lawn, and Bergenfield — plus every town in between.
Garage Addition Guides
Decisions that determine whether the project lasts and feels right.
Slab & Footings
- The slab gets pitched to the door with control joints, over compacted base and vapor barrier — flat enough to work on, sloped enough to drain.
- Frost-protected footings carry the walls; garages heave and crack without the same foundation respect a house gets.
- Wire mesh or fiber reinforcement in the slab handles vehicle point loads and the lift, compressor, or toolbox that arrives later.
- Apron and driveway tie-in get graded with the slab — water runs away from the door line, not under it.
- Floor drains where permitted, or center-pitch slabs, handle snowmelt off parked cars.

Garage Door Selection
- Insulated steel doors are the value standard; carriage-style wood and glass-panel aluminum carry the design tiers.
- The door dominates the addition’s curb face — its style gets chosen against the house, not from the catalog page.
- A quiet belt-drive opener with battery backup and smart control finishes the system; the door is the house’s biggest moving part.
- R-value matters on attached and conditioned garages — an uninsulated door undoes the insulated walls around it.
- Wind-load ratings apply to doors this size — the spec sheet item that matters in nor'easter country.

Heating & Insulation
- Insulated walls and ceiling turn the garage from thermal buffer to usable space and protect everything stored in it.
- A mini-split or gas unit heater makes winter projects realistic; sizing follows the insulation level, not the square footage alone.
- Gas appliances in garages follow ignition-height and protection rules; heater installs run through licensed trades.
- Attached garages get air-sealed at the house wall — fumes and conditioned air shouldn't trade places.
- Slab-edge insulation keeps a heated garage's floor workable in January.

Power & EV Charging
- GFCI outlets, overhead lighting, and task circuits are baseline; open-wall wiring is cheap insurance during the build.
- EV charger capacity is checked against the service panel; conduit to the parking stall is stubbed even if the charger comes later.
- Licensed electricians size feeders for tools, freezers, and chargers so the new garage does not trip the house main.
- A subpanel in the garage ends extension-cord engineering — circuits for door, charger, compressor, and bench.
- Conduit stubs to the yard and future shed run cheap while the trench is open.

Built-In Storage Systems
- Wall systems (slatwall, rail-and-hook) move storage up off the floor where the cars are supposed to be.
- Ceiling racks over the hood zones swallow the seasonal bins that otherwise claim a parking spot.
- A workbench run with dedicated outlets and task lighting turns the garage’s leftover wall into its most used square footage.
- Mezzanine storage over the hood zone exploits the tall framing attached garages usually get.
- Outlet strips at bench height every four feet — garages consume outlets faster than any room in the house.

Cost & Timeline Guide
- 1-car additions $40k–$80k; 2-car $65k–$140k; living space above is a different project at $150k–$320k+.
- Foundation, driveway rework, electrical service, and roof tie-in to the house are the big variables beyond wall square footage.
- Engineering and building permits set the clock; 14–24 weeks including inspections is a realistic full-cycle window.
- Attached vs detached changes the code package (fire separation, house-wall sealing) and the budget with it.
- Driveway rework is the quiet line item — approach angle and apron replacement ride most garage projects.

Your Garage Addition Process
Consultation
We walk the property, review setbacks, lot coverage, drainage, driveway access, and any town-specific garage rules.
Scope & materials
Architect produces drawings if needed; permits filed; door selections finalized; electrical scope set.
Build
Crew executes excavation, slab, framing, doors, electrical, finish.
Final walkthrough
Final walkthrough, garage door commissioning, punch-list closeout.
Garage Additions Are Site & Structure Jobs
Adding a garage means foundation, driveway grades, roof tie-in, and electrical service capacity — not only walls and a door. Setbacks and coverage rules in your Bergen municipality lock the footprint early.
We plan EV-ready conduit, lighting, and door openers during framing so you are not cutting finished walls later. Living space above a garage is a different, heavier scope with fire separation and HVAC implications.
Related: home additions, garage doors, carports. Request an estimate with lot survey notes if you have them and whether the garage is attached or freestanding.
Frequently Asked Questions
For 2026, single-car attached garages run $35,000-$75,000. Two-car attached garages run $55,000-$120,000. Three-car or finished garages with bonus space above run $100,000-$280,000+. Pricing and timelines are planning ranges.
Attached is more cost-effective and convenient. Detached allows different setbacks in some towns and gives a workshop or ADU more separation. We confirm what your town allows.
Yes. Bonus rooms, home offices, gyms, or accessory dwelling units (where allowed) all work above garages. Stairs and access design are part of the plan.
Yes. Building, electrical, and trade permits all apply. Garage doors, slab, and any framing changes require inspections.
Yes. Bergen Restoration is a registered New Jersey Home Improvement Contractor (NJHIC# 13VH08865500) with commercial general liability and workers' compensation coverage. Documentation is available on request, and homeowners should verify credentials before hiring any contractor.
The roof marriage decides whether the addition reads original — matched pitch, aligned eaves, and shingles woven or fully replaced. It's the design detail neighbors notice without knowing why.
Frost-depth footings with a slab pitched to the door, and in Bergen County soils, drainage thought at the apron so meltwater doesn't sheet in. The slab spec carries cars for decades.
Yes — a subpanel-ready run costs little during the build and answers EV charging, a shop circuit, and future projects. Conduit now beats trenching later.
Everything structural: deeper footings, engineered floor, stairs, egress, and insulation to living standard — a two-story project wearing a garage name. Priced honestly from day one.
Side- and rear-yard limits plus lot coverage decide the envelope — attached vs detached often gets decided by the survey, not the preference. We check before drawing.
They should be — the approach, apron pitch, and any drainage channel belong to the garage's function. A great garage behind a broken approach is half a project.
