Clear-span space for vehicles, storage, and projects
Custom Garages
Custom pole barn garages give you flexibility that standard garage kits can't match—taller doors for lifted trucks, wider bays for multiple vehicles, and clear-span interiors that stay open for storage or workspace. This guide covers planning, sizing, and what to expect when building a detached garage in Western Washington.

What to consider before you build
Planning Factors
Size and Layout
Start with what you need to store and how you'll use the space. A single-car garage may work for one vehicle, but consider whether you'll want room for a workbench, storage shelves, or a second vehicle in the future. Width matters—standard garage doors are 8-9 feet wide, but taller trucks or wider vehicles may need 10-foot doors or higher clearance.
Site Access
Consider how vehicles will access the building. Is there room to back a trailer in or turn around? Will the driveway need to be extended or improved? Site access affects both day-to-day use and construction logistics.
Permits and Regulations
Detached garages require permits in most Western Washington jurisdictions. Setback distances from property lines, height restrictions, and coverage limits all affect what can be built. Local jurisdictions may also have specific requirements for garage placement, driveway access, and impervious surface limits.
Intended Use
How the building will be used influences design decisions. Pure vehicle storage has different requirements than a workshop with power tools, or a space that might later be finished for other uses. Be realistic about current needs and likely future uses.
What fits in different sizes
Common Garage Dimensions
Single-Car Garages
Typically 12-14 feet wide by 20-24 feet deep. Fits one vehicle with room to walk around, or one vehicle plus storage along the walls. Minimum door height is 7 feet, but 8 feet is more practical for trucks and SUVs.
Two-Car Garages
Typically 22-26 feet wide by 22-24 feet deep. Accommodates two standard vehicles side-by-side with room to open doors. Larger versions (28+ feet wide) provide extra storage or work space.
Oversized Vehicle Garages
For lifted trucks, large SUVs, or vehicles with accessories: 14-16 feet minimum width per bay, with 9-10 foot doors. Height requirements vary based on vehicle clearance needs.
Depth Considerations
22-24 feet is standard for passenger vehicles. Longer vehicles (trucks with extended cabs, large SUVs) benefit from 26-28 feet of depth. Extra depth allows for workbenches or storage at the back without blocking vehicle access.
Height Considerations
Standard garage door height is 7 feet. Taller doors (8-10 feet) accommodate trucks, SUVs, and roof racks. Lift installations or overhead storage may require 12+ foot ceiling height.
Understanding the scope of your building project
What's Included
Structure and Shell
ProBuilt provides the complete post-frame structure including engineered trusses, pressure-treated columns, steel siding and roofing, overhead doors, and basic ventilation. The building is weather-tight and ready for use as vehicle storage or unfinished workspace.
Separate Considerations
Concrete work, electrical service, plumbing, insulation, and interior finishing are typically separate from the base building contract. Some property owners handle these items themselves, others coordinate them as separate phases. We can help you understand what's included and what should be planned separately.
Site Preparation
Site clearing, grading, and driveway improvements are property owner responsibilities. We can provide guidance on what's needed for construction access and long-term building performance.
