Choose the use before the dimensions
List the vehicles, tools, storage, and work activities the space should accommodate. Consider door opening, circulation, shelving, and the route from parked vehicles to the home. Storage needs can be more important than adding another nominal parking bay.
If future plumbing, conditioned space, or a room above is contemplated, disclose it early. Such uses can change the structure, systems, and approval questions. A garage should not be described as living space unless that use is appropriately designed and approved.
Compare attached and detached options
An attached garage needs coordination with the existing building, roof, access, and separation requirements. A detached structure still needs a workable driveway, utility route, drainage plan, and site placement. Compare both options against the property and intended use, not just their exterior appearance.
Discuss any proposed grading and the relationship to septic, well, and repair areas. Confirm jurisdiction and applicable approvals before finalizing the footprint.
Make the scope visible
An estimate should distinguish site work, foundations, structure, roof, siding, doors, electrical work, interior finish, and connection repairs. Clarify whether driveway changes, drainage work, and disposal are included. Product choices for garage doors should be coordinated with openings, headroom, and operating equipment.

Common project questions
- Can a future room above the garage be planned later?
- Some choices are costly to change after construction. Discuss the intended future use during design so structure, access, systems, and approvals can be evaluated.
- Is driveway work automatically included?
- No. Ask whether access changes, paving, drainage, and finish restoration are part of the written estimate.
