Full Breakdown

Honolulu's home-occupation standards flatly prohibit vehicle repair and painting as a home business, with one narrow exception: repairing or painting up to five vehicles owned by a household member in a year does not count as a prohibited activity. Anything beyond that threshold, or work on vehicles not owned by the household, falls outside what a home occupation may do.

Violations & Fines

Running a home auto-repair operation beyond the five-vehicle household exception violates ROH § 21-5.50-3(b)(3)(A) and is enforceable as a Land Use Ordinance violation.

No: vehicle repair and painting is a prohibited home occupation, except for repairing or painting up to five household-owned vehicles per year.
