Quick answer
Standard 2 car garage dimensions are 20 to 24 feet wide by 20 to 24 feet deep, with 22 by 22 feet the most common single-bay layout. A 16-foot-wide by 7-foot-tall door is typical. Minimum usable size is about 20 by 20 feet; add depth for trucks, storage or a workshop.
- 22 x 22 ft is the most common 2 car garage footprint, giving about 484 square feet.
- A 16 ft x 7 ft door fits two cars; 18 ft x 8 ft suits trucks and SUVs.
- Minimum depth is 20 ft, but 24 ft is needed for full-size pickups with room to walk around.
- Slab thickness is typically 4 in for cars, 5 to 6 in where heavy vehicles park.
Standard 2 Car Garage Dimensions: The Core Numbers
A standard two-car garage is typically 20 to 24 feet wide by 20 to 24 feet deep. In new U.S. homes, the 22x22 and 24x24 footprints are the most common because they balance cost, lot coverage and daily usability. Those numbers describe the exterior footprint, so the interior clear dimensions you actually park in are smaller.
Width is driven by door count and depth by vehicle length plus circulation. Two single doors or one double door set the minimum wall length, while depth has to hold the longest vehicle plus room to walk around it. A full-size pickup is roughly 19 feet long, so a 20-foot depth leaves almost no space at the front or rear bumper. That is why so many owners who park trucks or SUVs end up wishing they had built 24 feet deep.
For scale, a single-car garage usually runs 12x20 to 14x22. Doubling the width adds a second bay and a center column or pier between doors, which is why 2 car garage dimensions in feet rarely land at exactly twice a single bay.
Interior clear dimensions matter, not exterior. Subtract roughly 8 inches per side for wall framing, sheathing and drywall when converting exterior to interior. A 24-foot exterior width can yield about 22 feet 8 inches of clear space, and that difference decides whether two doors open fully.
Ceiling height baseline is 8 feet minimum, with 9 to 10 feet common when storage, lifts or tall vehicles are planned. If you are pricing a garage build or remodel, garage estimating services can turn these dimensions into a bid-ready takeoff.
Measure clear interior space, not the slab edge. Framing, sheathing and drywall can eat 16 inches of width across a two-car garage.
Minimum 2 Car Garage Dimensions You Can Actually Use
The practical floor for a 2 car garage size is 20 feet wide by 20 feet deep. That fits two compact or mid-size cars parked side by side, but door swing and walking space get tight fast. If either car is a crossover or SUV, you will feel the squeeze every morning.
The 3-foot rule is the one most owners underestimate. You want at least 2.5 to 3 feet between cars and between a car and the wall to open doors and carry groceries. Two 6-foot-wide cars plus three 3-foot gaps plus wall thickness pushes you past 21 feet of clear width, which is why 20 feet is a hard floor rather than a comfortable target.
For two full-size vehicles, minimum 2 car garage dimensions jump to 24 feet wide by 24 feet deep. You can drop to 22 feet wide if you accept narrower door-opening clearance and park both vehicles straight. Anything tighter than that turns a daily routine into a parking puzzle.
Code and lender minimums differ from comfort minimums. Some jurisdictions require a minimum parking stall of 9x18 feet or 10x20 feet, and two stalls plus circulation pushes past 20 feet wide. Check your local zoning and building department before you finalize a footprint, because a legal garage can still be an uncomfortable one.
HOA and appraisal implications matter too. An undersized garage can hurt resale even when it is legal, because buyers compare it against the 22x22 and 24x24 garages down the street. If you are weighing a tight plan against a slightly larger one, the extra two feet of width is usually the cheaper decision over the life of the house.
A 20x20 garage is a legal minimum in many places and a comfort minimum almost nowhere. If you park two full-size vehicles, plan on 24x24.
2 Car Garage Size Comparison Table
The table below compares common footprints using exterior dimensions. Interior 2 car garage square footage is lower once you deduct wall assembly, so treat the area column as a planning figure, not a clear-floor measurement. Door width scales with bay width: single 8 to 9 foot doors work for 20 to 22 foot garages, while a 16-foot double door suits 24 feet and wider.
| Footprint (W x D) | Interior area | Best for | Door width | Typical ceiling | Notes |
|---|---|---|---|---|---|
| 20 x 20 | ~400 sq ft | Two compact or mid-size cars | Two 8 ft singles or one 16 ft double | 8 ft | Minimum practical size; tight door swing |
| 22 x 22 | ~484 sq ft | Two mid-size cars, some storage | Two 9 ft singles or one 16 ft double | 8–9 ft | Most common production-home footprint |
| 24 x 24 | ~576 sq ft | Two full-size vehicles, workbench | One 16 ft double or two 9 ft singles | 9 ft | Comfortable daily use; room to walk around |
| 24 x 30 | ~720 sq ft | Two cars plus shop or storage bay | One 16 ft double plus man door | 9–10 ft | Extra depth for truck, bench and cabinets |
| 26 x 30 | ~780 sq ft | Two large vehicles plus equipment | Two 9 ft singles or one 18 ft double | 10 ft | Good for lifts, tall vehicles and storage |
| 30 x 40 | ~1,200 sq ft | Tandem parking or workshop | Two 10 ft singles or one 18 ft double | 10–12 ft | Shop-style layout; verify zoning and height |
2 car garage dimensions in feet drive the door and header sizes, so lock the footprint before you order a garage door. A 24-foot-wide garage with a single 16-foot door leaves about 4 feet of wall on each side, which is enough for trim and a man door but not much else. If you need the door and clearance numbers in detail, a takeoff of the opening schedule will catch conflicts before framing starts.
The area column uses exterior dimensions. Deduct roughly 8 inches per side for wall assembly before you compare it to a clear-floor measurement.
2 Car Garage Square Footage and Volume Math
Square footage is the first number most people calculate, and it is simple: multiply interior length by interior width. A 22 x 22 garage gives 484 square feet of floor area. A 24 x 24 gives 576 square feet, and a 24 x 30 gives 720 square feet. Those are interior dimensions, measured face-to-face of the finished walls.
Square footage alone misleads because it ignores height. A 24 x 24 garage with a 10-foot ceiling holds 5,760 cubic feet of volume (24 x 24 x 10). That volume drives heating and cooling load, ventilation strategy, and how much you can stack on wall shelves or a loft. Two garages with the same 2 car garage square footage can behave very differently once ceiling height changes.
For storage planning, subtract the vehicle footprint plus circulation. A typical car occupies roughly 40 to 60 square feet of floor area, and each bay needs about 20 to 30 square feet of circulation for doors and walking space. A 24 x 24 garage with two vehicles therefore has about 576 minus (2 x 50) minus (2 x 25) = 426 square feet of usable leftover area, though that space is distributed around the cars rather than in one block.
Exterior footprint runs larger than interior square footage, typically 10 to 15 percent more once wall thickness and any bump-outs are counted. A 24 x 24 interior is closer to a 25 x 25 exterior footprint. That difference matters because concrete, framing, drywall, insulation, and roofing quantities all come from exterior dimensions and linear feet, not the interior number. If you want the quantities checked, a quantity takeoff service converts these dimensions into material counts and cubic yards.
Always confirm whether a quoted garage size is interior or exterior. Mixing the two throws off concrete and drywall quantities by 10 percent or more.
Worked Example: 2 Car Garage Concrete Slab Dimensions
Example only. Assume a 24 x 24 exterior footprint, 8-inch stem walls, and a 4-inch slab. These numbers are illustrative; your plan governs.
Slab area: 24 x 24 = 576 square feet.
Slab volume: 576 x (4 ÷ 12) = 192 cubic feet. Convert to cubic yards: 192 ÷ 27 = 7.11 cubic yards. Add 10 percent waste: 7.11 x 1.10 = 7.82, so order about 7.8 cubic yards.
Perimeter for footing and stem wall: 24 x 4 = 96 linear feet. That perimeter drives formwork, footing concrete, anchor bolts, and sill plate material.
Rebar: at 16 inches on center each way, spacing in feet is 1.33. One direction: 24 ÷ 1.33 = 18 bars. The other direction: 18 bars. Total 36 bars. At 24 feet each: 36 x 24 = 864 linear feet, plus laps and dowels. Typical lap is 40 bar diameters, so add roughly 5 to 10 percent for laps depending on bar size and layout.
Vapor barrier: cover the full slab area plus 6-inch laps and turn-up at the stem wall, so order at least 576 square feet plus overlap, commonly a 15 x 100 foot roll for a garage this size.
Floor drain: if the slab slopes to a drain, allow for the drain body, trap primer, and pipe below slab before the pour. A 1/8 inch per foot slope toward the drain or door is common. Concrete takeoff and foundation takeoff are separate scopes; if you need both priced, a concrete estimating service and a foundation estimating service will each carry their own line items.
Order concrete in whole or half yards and confirm the plant's minimum. A short load charge can cost more than the extra half yard.
2 Car Garage Door Dimensions and Clearances
Garage door size drives the header, the wall layout, and how comfortably you park. Single doors are commonly 8, 9, or 10 feet wide by 7 or 8 feet tall. A double door is commonly 16 feet wide by 7 or 8 feet tall. Two 9-foot singles are a common choice when you want separate openings and less header span.
Headroom is the clearance above the opening. A standard sectional overhead door needs about 12 inches above the opening for tracks and springs. Low-headroom kits exist but limit door height and often require torsion springs mounted differently, so verify before framing. The header itself must be sized by the structural plan; a wider opening means a deeper header and less room for the door track.
Side room matters too. Allow at least 3.5 to 4.5 inches on each side of the opening for jamb and vertical track, and more if torsion springs or a jackshaft operator sit beside the opening. If you plan a 16-foot door in a 24-foot wall, you have 4 feet on each side, which is comfortable. A 16-foot door in a 20-foot wall leaves only 2 feet per side, which is tight for springs and trim.
An 8-foot-tall door is common when trucks, lifts, or tall SUVs are stored, because a 7-foot door can be too low for a lifted vehicle or a roof rack. Finally, keep the door width at least 1 foot narrower than the bay so cars can angle in without scraping. A 9-foot door in a 10-foot-wide bay is workable; a 9-foot door in a 9-foot bay is not.
Confirm door headroom and side room on the shop drawing before you frame. Moving a header after the wall is up is expensive.

2 Car Garage Framing Dimensions and Structure
The 2 car garage framing dimensions start with the walls. Exterior walls are typically framed with 2x4 or 2x6 studs at 16 or 24 inches on center. In colder climates, 2x6 studs are more common because they provide a deeper cavity for insulation. A 24-inch on-center layout uses fewer studs, but it can limit certain exterior finishes and requires closer attention to sheathing spans.
The header over the garage door is the most critical structural element. A 16-foot opening usually needs a built-up header sized by a structural engineer. Do not guess the size from a rule of thumb; the header must carry the roof and wall loads above the opening. For a 16-foot span, a doubled or tripled 2x12 may work in some conditions, but engineered lumber or a steel beam is often required.
The roof structure is usually prefabricated trusses at 24 inches on center or stick-framed rafters. Roof pitch typically ranges from 4:12 to 8:12 to match the house. A steeper pitch sheds water and snow better and may allow more attic space. When you estimate framing, list trusses by count and span, and include bracing and sheathing.
Sheathing is commonly 7/16-inch OSB or plywood on walls. On an attached garage, the wall shared with the dwelling needs 5/8-inch drywall for fire separation. That drywall is part of the framing and drywall takeoff, not a finish item. For accurate quantities, use a framing takeoff service and a lumber takeoff to convert linear feet of walls, headers, and trusses into board feet and piece counts.
Ceiling height and truss design determine whether attic storage is usable. Standard trusses with a low bottom chord may leave only a shallow space. If you want storage, specify attic trusses with a raised bottom chord and a steeper pitch. That decision affects the header, wall height, and roof framing, so it must be made before you order materials. For electrical rough-in, plan for a circuit breaker panel and led lighting fixtures to meet code and efficiency goals.
Never size a garage door header from a chart alone. Span, roof load, and snow load vary by location, so have an engineer confirm the member and connection details.
2 Car Garage Layout Ideas That Fit Real Vehicles
The side-by-side layout is the most common 2 car garage layout idea. Two bays share a 16-foot door or have two 9-foot doors. This layout works well for daily drivers because each car has its own path in and out. A typical 2 car garage size for this layout is 20 to 24 feet wide by 20 to 24 feet deep. The 2 car garage dimensions you choose must leave clearance for doors to open and for people to walk between vehicles.
A tandem layout places two cars nose-to-tail. The garage is narrow but deep, often 12 to 14 feet wide by 30 to 40 feet deep. This fits narrow lots and long driveways. The trade-off is that the rear car must be moved to access the front car. Tandem garages also need careful lighting and ventilation because the rear bay is far from the door.
The shop-plus-parking layout dedicates one bay to a car and one bay to a workbench and tools. A 24x30 garage or larger gives room for a bench along the back wall and storage on the side. In this layout, keep the parking stall at least 10 feet wide and 20 feet deep. The work area should not block the path from the car to the house door.
Storage strategies matter as much as bay size. Wall-mounted cabinets above hood height keep the floor clear. Ceiling racks hold seasonal items but must not hang so low that they block the garage door swing. A bump-out for trash or lawn equipment adds floor area without widening the whole garage. For a full quantity takeoff of these options, a residential estimating service can price each layout.
Circulation is the final check. Keep a 3-foot clear path from the car door to the house door. Avoid parking under overhead storage that blocks the door swing. If you cannot walk around the car with the doors closed, the layout is too tight.
Measure your actual vehicles, including mirrors folded and doors open, before you lock a layout. Published vehicle dimensions rarely match real-world clearance needs.
Site Planning: Apron, Driveway and Turn Radius
The apron is the paved area directly in front of the garage door. It is typically 10 to 20 feet deep and at least as wide as the door plus 2 feet on each side. A 16-foot door needs an apron at least 20 feet wide. The apron must slope away from the building so water does not run under the door.
Driveway width for two cars is commonly 16 to 24 feet, with 20 feet a comfortable standard. A 16-foot driveway feels tight when both cars are parked and doors are open. A 20-foot driveway gives room to walk between vehicles. The driveway connects the apron to the street or parking area and must match the apron width at the transition.
Turn radius and back-up space depend on the vehicle. A 20-foot-wide driveway with a 25-foot apron handles most passenger vehicles. Larger trucks and SUVs need more. If the driveway meets a street at a sharp angle, drivers may need to make a multi-point turn. Check the turning radius of the largest vehicle that will use the garage.
Slope is critical. A 1 to 2 percent slope away from the garage door sheds water. Steeper aprons can scrape low bumpers and make it hard to push a trash bin. The slope should continue along the driveway to a drainage point. For asphalt or concrete quantities, measure the apron and driveway in square feet and convert to cubic yards of concrete or tons of asphalt. A sitework estimating service and an asphalt paving estimator can convert those areas into material volumes and costs.
Keep the apron and driveway square footage in your takeoff separate from the garage slab. They use different subbase, thickness, and reinforcement. Mixing them into one line item hides cost and creates errors in the bid.
Verify the driveway slope and apron depth against the local code and the vehicle's approach angle. A steep apron can make a finished garage unusable for low-clearance cars.
Electrical, Lighting and EV Charger Planning
Plan at least one GFCI-protected electrical outlet per bay, plus one near the garage door opener and one near the workbench. Garages are damp, dusty and often unheated, so the National Electrical Code requires 120-volt receptacles in garages to have GFCI protection. A single GFCI device can protect downstream outlets on the same circuit, which keeps the device count and cost down.
Lighting is where most owners underbuild. For a working garage, aim for 50 to 80 lumens per square foot; a parking-only garage can get by with 20 to 30 lumens per square foot. A 24-foot by 24-foot garage is 576 square feet, so a working layout needs roughly 28,800 to 46,080 lumens total. LED shop lights rated at 4,000 to 5,000 lumens each mean six to twelve fixtures, split across two or three switched rows so you are not lighting the whole shop to grab a tool.
EV charger planning starts at the panel. A Level 2 charger needs a 240-volt circuit, commonly 40 to 60 amps, run from the main panel or a garage subpanel. Wire size and conduit depend on the amperage and the run length, so a 60-amp circuit 80 feet from the panel is a different wire size than the same circuit 15 feet away. If you are weighing a charger against rooftop solar, our solar and EV charging estimating services cover both sides of that decision.
A subpanel in the garage simplifies future circuits for lifts, welders, heaters or a second EV charger. Size the feeder for the loads you expect plus spare capacity, and leave breaker spaces open. If the garage is detached, the subpanel also gives you a local disconnect. For circuit-by-circuit takeoff, our electrical estimating services price panels, feeders and devices from the plans.
Put the EV charger circuit on the side of the garage closest to where the car nose parks. A charger on the wrong wall can force a longer, more expensive conduit run later.
2 Car Garage Dimensions for Contractors: What to Verify
- Confirm interior clear dimensions, not exterior. Door tracks, lifts and storage racks fit to the inside face of the walls, so verify clear width and depth before ordering anything.
- Check the door opening width and height on the plans. A nominal 16-foot door needs a rough opening wider than 16 feet, and the headroom above the opening must clear the tracks and opener.
- Verify header size and ceiling height together. A deep header eats headroom, and a low ceiling limits both lift height and opener options.
- Confirm slab thickness and stem wall height above slab. These two numbers set your clear height at the door and your anchor bolt elevations.
- Walk the foundation details. Footing depth, rebar spacing, vapor barrier and anchor bolt layout belong on your 2 car garage dimensions for contractors checklist before concrete is placed.
- Reconcile the 2 car garage framing dimensions with the footprint. A 24x24 exterior footprint with 2x6 walls yields roughly 23 feet by 23 feet 8 inches interior, which is what actually governs door and lift fit.
- Run a clash check. Takeoff software and BIM models catch conflicts between door tracks, lights and storage racks before they become field changes.
Use blueprint takeoff and estimating to pull these dimensions from the drawings, and BIM estimating services when the model needs coordination across trades. A 24x24 exterior footprint with 2x6 walls yields roughly 23 feet by 23 feet 8 inches interior once you account for the wall thickness. That roughly 23-foot clear width is the number a two-post lift and a 16-foot door have to share.
Measure the interior clear dimensions on site after framing, not just from the plans. Framing tolerances and furring can shave inches off the width you designed for.
Common Mistakes in 2 Car Garage Planning
- Sizing by car width only. Two cars at 6 feet wide each fit in 12 feet, but door swing and walking space need more. Leave at least 2 to 3 feet between cars and 2 to 3 feet to each wall.
- Forgetting garage door headroom and side room. The overhead door needs vertical track space above the opening and horizontal track space along the ceiling. If the ceiling is too low or a beam crosses the track path, the opener or tracks will not fit.
- Skipping the vapor barrier under the slab. Without a vapor barrier, moisture migrates up through the concrete and fails floor coatings, adhesives and stored goods. Specify it and inspect it before the pour.
- Undersizing the electrical panel. Adding an EV charger, heater or welder to a full panel means a service upgrade. Plan the subpanel and spare breaker spaces before the drywall goes up.
- Ignoring roof pitch and truss design for attic storage. A low roof pitch or a truss with a low bottom chord leaves attic space you cannot stand in or load. Check the truss design before you plan storage up there.
- Not checking local code. Minimum parking stall size and fire separation between the garage and house are set locally. Confirm both before you finalize the layout.
If you want a second set of eyes on your dimensions and scope, an estimate review and second-opinion audit will catch these issues before they hit the field.
Most of these mistakes are cheap to fix on paper and expensive to fix in concrete. Resolve them at the drawing stage.
2 Car Garage Cost Calculator: What Drives the Number
A 2 car garage cost calculator is a rough tool. It gives you a starting point, but the real number depends on your region, site conditions, foundation type, finishes, and whether the garage is attached or detached. Treat any online calculator as a budget check, not a bid.
Typical U.S. cost ranges for a basic detached 2 car garage often fall between $25,000 and $60,000, or roughly $50 to $100 per square foot. These ranges vary widely by region, scope, and date. An attached garage may cost less per square foot because it shares walls and roof with the house, but it also triggers different code requirements for fire separation and structural connection.
To understand what drives the number, break the project into cost buckets. Each bucket has its own quantities and unit costs:
- Sitework and excavation: Clearing, grading, and digging for footings. Includes haul-off of spoils.
- Concrete slab and footings: The slab, thickened edges, and any perimeter footing. Measured in cubic yards of concrete and linear feet of rebar.
- Framing and trusses: Wall studs, plates, headers, sheathing, and roof trusses. Measured in board feet or linear feet of lumber and sheets of sheathing.
- Roofing: Underlayment, drip edge, and shingles or metal panels. Measured in squares (100 square feet).
- Siding and exterior trim: Siding material, house wrap, and trim. Measured in square feet of wall area.
- Garage door and opener: The overhead door, tracks, springs, and opener. Priced per unit, including installation.
- Electrical: Outlets, lights, switches, and wiring. May include a subpanel and a dedicated circuit breaker if detached. Consider led lighting for energy efficiency.
- Finishes: Drywall, paint, and floor coating if you finish the interior.
An attached garage shares walls and roof with the house, which changes cost allocation. You may save on siding and roofing, but you will pay for fire-rated wall assemblies and structural connections. Code requirements for attached garages often include a fire separation wall and self-closing door between the garage and living space.
A professional takeoff turns the calculator estimate into a bid-ready number. It gives you exact quantities for concrete, lumber, rebar, and finishes, so you can price the job accurately. For a deeper look at how cost estimating works, see our construction cost estimating services page. If you need a budget number for planning, our budget estimating services can help.
Online calculators rarely include sitework, permits, or utility connections. Always add 10–20% contingency for unknowns like poor soil or high water table.
When to Get a Professional Estimate or Takeoff
You should get a professional estimate when you are bidding, financing, or comparing multiple garage designs. A detailed takeoff gives you exact quantities: cubic yards of concrete, linear feet of rebar, sheets of sheathing, and squares of roofing. These numbers let you price the job with confidence and avoid underbidding.
For contractors, a third-party takeoff reduces bid risk and speeds up bid day. Instead of spending hours measuring and counting, you get a ready-to-use quantity list. That frees your team to focus on pricing and subcontractor quotes. If you are a contractor, our garage estimating services are built for this. For the concrete scope, see our concrete estimating services page.
Scope Precision Estimate offers same-day quotes and bid-ready takeoffs in 48 hours, with 20 percent off for new clients. We work from your plans to deliver clear, organized quantities. Whether you need a full takeoff or just a second opinion, our construction takeoff services can help you win more work with accurate numbers.
A takeoff is not a price. It gives you quantities; you apply your own labor and material rates to get a bid.
Frequently asked questions
What is the most common 2 car garage size?
The most common 2 car garage size in U.S. residential construction is 22 feet wide by 22 feet deep, roughly 484 square feet. This fits two mid-size vehicles with door swing clearance and a walkway between them. Production builders often use 20 by 20 feet to save lot area, while custom homes commonly go to 24 by 24 feet or larger for storage, a workbench or a third bay.
How wide is a 2 car garage in feet?
A 2 car garage is typically 20 to 24 feet wide, measured inside face to inside face of the finished walls. Twenty feet is the practical minimum for two cars side by side; 22 feet is comfortable; 24 feet allows shelving or a workbench along one wall. If you need to park two full-size trucks, plan on 24 feet minimum and confirm mirror-to-mirror width, which can exceed 8 feet.
What is the minimum depth for a 2 car garage?
The minimum depth for a 2 car garage is 20 feet inside, but 22 to 24 feet is far more usable. A full-size pickup is roughly 19 feet long, so a 20-foot-deep garage leaves almost no room to walk in front of it. Add 2 to 3 feet of depth for a workbench, and check local code for any required clearance in front of an entry door.
How much square footage is a 2 car garage?
A 2 car garage is typically 400 to 576 square feet of interior floor area. A 20 by 20 foot garage is 400 square feet; 22 by 22 is 484; 24 by 24 is 576. Multiply interior width by interior depth, not the exterior footprint, and deduct any thickened piers or mechanical platforms. For slab and framing quantities, see our garage estimating services.
What size garage door do I need for two cars?
For two cars, a single 16-foot-wide by 7-foot-tall door is standard, and an 18-foot-wide by 8-foot-tall door is common for trucks and SUVs. Two 9-foot-wide single doors are an alternative that reduces header span. Leave at least 12 to 18 inches between the door edge and the side wall, and confirm headroom for the door tracks and opener.
How thick should a 2 car garage concrete slab be?
A 2 car garage slab is typically 4 inches thick over a compacted granular base, with 6x6-W1.4xW1.4 welded wire mesh or macro fibers. Use 5 to 6 inches where full-size trucks, trailers or lifts will park, and thicken the slab to 12 inches at the perimeter footing. Slopes run about 1/8 inch per foot toward the door for drainage.
Do I need a subpanel in my garage for an EV charger?
Often yes. A Level 2 EV charger draws 32 to 48 amps continuously, which is usually too much for an existing 15 or 20 amp garage circuit. A 60 to 100 amp subpanel fed from the main service gives you capacity for the charger plus lighting, outlets and a future shop tool. Confirm available service capacity and conduit size with a licensed electrician before rough-in.
How much does it cost to build a 2 car garage?
A detached 2 car garage typically costs $45 to $90 per square foot for a basic unfinished build, and $90 to $150 per square foot with finished interior, insulation, HVAC and upgraded doors. Regional labor rates, foundation type, roof pitch and site access move the number significantly. Get a line-item takeoff before you commit to a budget.
