Business licenses and permits in Twin Falls County, Idaho
Twin Falls County, Idaho, seat Twin Falls; population 96,509 (U.S. Census Bureau 2024 estimate). The Board of County Commissioners, through the County Clerk, issues annual county beer, wine and liquor-by-the-drink licenses and handles alcohol beverage catering permits for events outside city limits; under Idaho Code 23-1016(1) a city may not license a beer retailer until the retailer holds the county license, so the county beer license applies to premises inside the cities as well. Community Development Services runs the Building Department and Planning & Zoning; County Code 8-1-4 makes the county zoning code "effective within the unincorporated portions of Twin Falls County". The Sheriff issues the county peddler, solicitor and transient merchant license under County Code Title 3, Chapter 2. South Central Public Health District handles septic permits for construction in the county. The county's 2025 tax levy sheet lists city levies for eight incorporated cities: Twin Falls, Buhl, Filer, Kimberly, Hansen, Murtaugh, Castleford and Hollister. Each city's own business license, building and zoning rules for premises inside its limits stack on the county and state records.

- Retail storesRetail is the lightest common permit load, but the sales tax permit and the certificate of occupancy are non-negotiable in every jurisdiction.See the full permit list
- Salons and barbersPersonal care is licensed at state board level as well as locally, so the shop license and the practitioner licenses are separate obligations.See the full permit list
- Food trucksMobile food is the one category with no certificate of occupancy — but it gains a commissary agreement, and the unit itself is inspected rather than the premises.See the full permit list
- Fitness studiosPrepaid memberships trigger state registration and often a surety bond, which catches operators who budgeted only for the fit-out.See the full permit list
- Childcare centresThe heaviest permit load of any small business: state agency licensing, per-person background checks, and a stricter fire standard than ordinary commercial use.See the full permit list
- Contractors and tradesLicensed at state board level rather than locally, and the only common category with no premises permits at all — the bond is usually the long pole.See the full permit list
- Auto repair shopsOrdinary commercial permitting plus an environmental layer: waste oil, solvents and stormwater are each registered separately.See the full permit list
- Veterinary clinicsA state facility permit, controlled substances registration at both state and federal level, and a medical waste manifest — none of which a general business license covers.See the full permit list

What do these permits involve in Twin Falls County?
Building and Occupancy Permit (unincorporated Twin Falls County)
The county's Commercial Building Permit Information brochure (Revised 07-2026) states that "A building permit is required any time a building or structure is erected, constructed, remodeled", sets out when an occupancy permit is needed, including a change in the type of use of a building, and states: "All permits expire after 180 days from the date of permit issuance or the date of last inspection." It also states: "The minimum penalty for work started without a permit is an amount equal to the building permit fee." The county's Commercial Building Permit Application (Updated 7/2026) states: "Plan Review Fee of 65% of permit fee or $200 (whichever is greater) due when submitting completed application. Building Permit Fee will be collected when the permit is Issued." The same form asks for a septic permit or comment letter from South Central Public Health District and a site plan stamped by the district. The Board of County Commissioners' August 2025 minutes record the adoption on 14 August 2025 of Resolution No. 2025-035, which adopted a Building Valuation Table (Exhibit A), Zoning Permit Fees (Exhibit B) and Misc. Building Permit Fees (Exhibit C); the minutes do not reproduce those exhibits. The Building Department issues these permits for the unincorporated county, as listed on the Community Development Services page. Twin Falls County offices are at 630 Addison Ave W, Twin Falls, ID 83301; the county's main line is 208-736-4000.
Zoning Approvals: Home Occupation, Conditional Use and Temporary Use (unincorporated Twin Falls County)
County Code 8-1-4 (Ord. 286, 8-19-2024) states: "This zoning code is effective within the unincorporated portions of Twin Falls County". The Planning & Zoning applications page offers Home Occupation, Conditional Use, Temporary Use, Floodplain Development, Variance and Rezone applications among others. A home-based salon, contractor's office, small childcare or fitness business in the unincorporated county uses the Home Occupation application; a business whose use needs a conditional use permit in its zone applies through a public hearing. The Community Development Services page cites Twin Falls County Code 8-6(A-F) and Idaho Code 67-6521 for conditional uses and states: "Uses that are not listed in the ordinance will not be approved." It also states that the Planning & Zoning Commission meets on the second Thursday of each month at 6:30 p.m., and that when more than eight applications arrive in a month a request can move to the following month. Zoning fees are those of Exhibit B to Resolution No. 2025-035, adopted by the Board of County Commissioners on 14 August 2025 as recorded in its August 2025 minutes. Contact Twin Falls County Planning & Zoning, 630 Addison Ave W, Suite 1100, Twin Falls, ID 83301, pandz@tfco.org, or the county's main line, 208-736-4000.
Septic (Subsurface Sewage) Permit or Comment Letter (South Central Public Health District)
The county's Commercial Building Permit Application (Updated 7/2026) lists among the documents required from the South Central District Health Department, 1020 Washington N. (CSI Campus): "Septic Permit or comment letter for any proposed construction", and it requires a site plan "Stamped by South Central Health District". A business building on a site in Twin Falls County that is served by a septic system therefore obtains the district's septic permit, or its comment letter, before the county building permit. The district's Septic Permit Application (SCPHD 7.2026) lists "Non-Residential (commercial/industrial)" among its proposed usages and has a box for the fee paid; the amount is set by the district. South Central Public Health District's office is at 1020 Washington St N, Twin Falls, ID 83301.
