Garage Build Cost Calculator

Estimate the cost of constructing a new US garage by floor area, structure, finish, and site conditions.

How this estimate is calculated

New garage floor area uses an installed construction baseline that already represents normal foundation, walls, roof, and standard garage work. Garage type, specification, and site conditions are explicit per-square-foot adjustments. Electrical, insulation, an additional door, and plumbing remain fixed allowances.

This is a planning estimate, not a contractor quote. Actual contractor quotes vary by location, specification, site conditions, labour, and project requirements.

Useful cost information

Planning assumptions

  • This estimates new garage construction, not conversion of existing garage space.
  • Permits, design, utility relocation, exceptional excavation, and unusual structural engineering are excluded.
  • Actual quotes vary with location, specification, access, and ground conditions.
