Example Pricing Benchmarks
| Scenario | Planning Range | Project Notes |
|---|---|---|
| 1-car detached garage | $2,000-$6,000 | Lowest range when the garage is wood-framed, empty, and close to driveway access. |
| 2-car detached garage | $4,000-$12,000 | Roofing, siding, framing, and debris volume usually double the removal scope. |
| Attached garage plus slab | $6,000-$18,000+ | Separation work, concrete breaking, utility checks, and protection raise the budget. |
Permit and risk checks
Many cities treat detached accessory structures differently from attached garages. Verify permit rules before disconnecting utilities or removing a shared wall.

Frequently Asked Questions
Is a detached garage cheaper to demolish than an attached garage?
Usually yes. Attached garages require more protection, utility checks, and careful separation from the house.
Should slab removal be included in the garage demolition bid?
Only if you need the concrete removed. Keep slab removal as a separate line item so bids are easy to compare.
