What does a auto repair shop need in Knox County Tn 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 Knox County Tn: Air Quality Permit-by-Rule — Auto Body Refinishing and Automotive Repair Shop Licensing — Tennessee Position.
Air Quality Permit-by-Rule — Auto Body Refinishing
As published on the Knox County Department of Air Quality Management's Permit-by-Rule page, auto body refinishing operations that do not complete more than 50 jobs per week are eligible for a Permit-by-Rule, and 'Any person submitting a Notice of Intent (NOI) to construct an eligible source must pay a fee of $150', which is not refunded if the Notice of Authorization is denied or the NOI withdrawn; Regulation 25 states the same $150. The NOI is filed at least seven days before construction starts, and the Notice of Authorization then 'acts as both a construction and operating permit and has no expiration date'. Each facility under a Permit-by-Rule also pays an annual emission fee, due September 30 for sources other than gasoline dispensing facilities, under the fee schedule in Regulation Section 25.9; the current dollar amount is not published on the Permit-by-Rule page, so call 865-215-5900 for it. A body shop that grows past 50 jobs a week must apply for a construction permit instead.
Automotive Repair Shop Licensing — Tennessee Position
The Department of Commerce and Insurance publishes the complete list of every programme its regulatory boards division runs — twenty-one of them, accountancy through scrap metals — and that list names no automotive repair programme, so no state repair-shop license fee applies; the Secretary of State's index of every agency holding administrative rules likewise has no chapter for automotive or motor vehicle repair. The only vehicle-trade chapter belongs to the Motor Vehicle Commission, whose fee rule enumerates every category it licenses and includes no repair shop. What does bite is selling or dismantling rather than repairing: a dealer license is $600 for two years, an automotive dismantler and recycler the same, an auction $1,200. Business tax applies to repair services, but that is a tax registration rather than a license.
The other 7 local permits in the tables apply to every type of business in Knox County Tn, TN; what each one involves is set out on the Knox County Tn permits page. The 5 state-level registrations apply to every type of business across TN and are covered on the TN state page.
