Twin Falls County, ID: Auto Repair on Residential Property (2026)

Twin Falls County treats a home-based auto repair operation as a home occupation under Title 8, Chapter 10, but flags it for extra scrutiny. Section 8-10-1 lets the Zoning Administrator approve most home occupations administratively, but specifically calls out gun shops, daycare, and auto repair or parts as sensitive-nature businesses that may instead be scheduled for a public hearing before the Planning and Zoning Commission or Board. If approved, the operation still has to meet every general home occupation standard in section 8-10-3: no external alterations or construction features that are not customary in a dwelling, no external sign of the business apart from a permitted sign, and the use cannot change the character of the dwelling or affect neighboring uses.

For an auto repair use specifically, subsection G caps the work at no more than three vehicles being worked upon at any time, and requires adequate disposal of waste and salvage materials, meaning no unsanitary accumulation of any kind and no visible evidence of collected waste or salvage parts. The operation also needs adequate off-street parking, cannot create excessive traffic noise or odors, and, if it uses an accessory building or enclosure, that structure cannot exceed one thousand six hundred square feet. Because the code requires articles worked on to stay out of sight within a structure or enclosure, an at-home auto repair operation in the unincorporated county cannot run as an open-air driveway business; it has to be enclosed, parking- and noise-conscious, and capped at three cars at a time, or the Zoning Administrator can revoke the approval.
