What does a auto repair shop need in New Castle County that other businesses do not?
2 of the 2 permits particular to a auto repair shop here apply to no other business type we cover in New Castle County: Auto Body Shop Air Quality Permit and Auto Repair Shop License — Delaware position (general business license applies).
Auto Body Shop Air Quality Permit
This permit reaches only auto body and collision shops that do spray-coating or painting — not general mechanical repair, which needs no equivalent state environmental permit. A shop generating hazardous waste such as used oil or solvents has separate hazardous waste compliance obligations under the same environmental agency, addressed through guidance rather than a standalone license fee.
Auto Repair Shop License — Delaware position (general business license applies)
The Division of Revenue's detailed list of licenses and tax rates contains no distinct auto repair classification, so a shop doing general mechanical work licenses under a general classification such as General Services and pays the same $75 business license as any other service business; no separate state repair license fee is shown here. Delaware Business First Steps lists a separate air quality permit for auto body shops that use spray coatings above certain levels, recorded here as its own item because it applies only to that narrower category of work.
The other 2 local permits in the tables apply to every type of business in New Castle County, DE; what each one involves is set out on the New Castle County permits page. The 6 state-level registrations apply to every type of business across DE and are covered on the DE state page.
