Quick Answer
Yes, you can deduct a detached garage or studio if it's used exclusively for business and qualifies under IRS rules. Unlike home offices, detached structures don't need to be your principal place of business - they just need exclusive business use. You can deduct 100% of utilities, insurance, and maintenance costs for the detached structure.
