What is the ideal garage size for a 2-car garage in a Moncton NB subdivision?

The ideal size for a two-car garage in a Moncton subdivision is 24 feet wide by 24 feet deep at minimum, with 24 by 28 or 24 by 30 being the preferred dimensions if your lot and setback requirements allow. This gives you enough room to park two vehicles comfortably while leaving space to open doors, walk between cars, and store basic garage essentials along the back or side walls.

A 24x24 garage provides 576 square feet of floor area and is the most common size built in Moncton-area subdivisions like Royal Oaks, Mapleton, and Riverview developments. At this size, you can park two mid-size cars or SUVs side by side with about 2 to 3 feet of clearance between them and roughly 30 inches of clearance on each side wall. However, if either vehicle is a full-size pickup truck — which is extremely common in New Brunswick — a 24x24 starts to feel tight, particularly for depth. Modern full-size trucks like the Ford F-150 or RAM 1500 are 20 to 22 feet long, leaving only 2 to 4 feet of clearance front and back in a 24-foot-deep garage. You will find yourself pulling in carefully every time and having minimal room for a workbench, shelving, or seasonal storage at the back.

This is why many experienced NB garage builders recommend stepping up to 24x28 or 24x30 if your lot allows it. The extra 4 to 6 feet of depth adds meaningful storage and work space at the back of the garage without significantly increasing the footprint's impact on your yard. In terms of cost, going from 24x24 to 24x30 adds roughly $5,000 to $10,000 to the total project in the Moncton market — a modest premium that pays dividends in daily usability for decades.

Width considerations are equally important. A 24-foot-wide garage accommodates a standard 16-foot double garage door with 4 feet of wall framing on each side. If you prefer two separate single doors — which many NB homeowners choose for aesthetic reasons and because single doors seal better against winter wind — you will need those 24 feet to fit two 9-foot doors with a centre post and side clearances. If you want to fit wider vehicles or open truck doors fully, consider going to 26 or 28 feet wide, though this requires confirming with the City of Moncton's planning department that you meet side-yard setback requirements, which are typically 5 feet minimum in residential zones.

Ceiling height in a standard Moncton subdivision garage is 8 to 9 feet to the bottom of the trusses, which is sufficient for most vehicles. If you plan to install overhead storage racks, a garage door opener with high-lift track, or if you want clearance for a roof-top cargo box on an SUV, specify 9-foot walls with your builder. The cost difference between 8-foot and 9-foot walls is typically only $500 to $1,000 in additional framing lumber and siding.

For Moncton's climate, keep in mind that your garage foundation must reach below the frost line of approximately 4 feet (1.2 metres). This applies whether you build a full perimeter frost wall or a thickened-edge slab — check with the City of Moncton's building inspection department for the approved foundation types in your specific subdivision. Many newer Moncton developments have specific architectural controls that dictate whether the garage must be attached, the maximum footprint size, and acceptable exterior materials, so review your subdivision's covenants before finalizing plans.

Budget-wise, a standard 24x24 two-car detached garage in Moncton runs $40,000 to $65,000 with foundation, framing, roofing, vinyl siding, a 16-foot insulated overhead door, service door, basic electrical, and a concrete slab. A 24x30 version falls in the $48,000 to $72,000 range.
