Casper, WY Business License Guide

Casper city licenses and permits

What the city calls the local requirement

The city uses the term “Business Licenses” on its official page. It also has pages for health licenses, liquor licenses, liquor permits, itinerant merchant and unsolicited salesman permits, mobile vendor parking permits, and special event permits. The City Clerk’s Office is the city office named for reviewing and processing many of these items.

The Business Licenses page says applicants should create an account for the business and apply through the city self-service page. The city’s current posted Business License categories, fees, and terms are:

If one business performs more than one listed activity, the city says a license is generally required for each fee classification. Posted fees are not prorated and are not transferable unless the City Council approves an application. Confirm the current amount and documents in the city portal before paying.

Do not call every local step a “business license.” Zoning approval, a sign review, building permit, fire inspection, health license, contractor license, mobile vendor parking permit, liquor permit, and food license can be separate.

Who should check with the city early

Check the city before opening if your business involves alcohol, mobile vending, door-to-door sales, taxis or vehicles for hire, pawnbroking, secondhand goods, junk dealing, food service, lodging, events, construction, commercial tree work, signs, customer visits, or a physical location.

City health licenses are a separate layer

Casper says a business affecting public health must begin with the Casper-Natrona County Health Department for inspection before the city issues its health license. Massage-therapy licenses and permits are the stated exception to the county-inspection step. The city currently posts these health-license fees:

These city fees do not replace the health department’s plan review, inspection, or other food-safety steps. If several fee classes fit, ask whether each applies.

Mobile vendors, events, and alcohol

For public parking spaces in the Downtown/Old Yellowstone District, Casper requires sponsorship from a brick-and-mortar business within 30 feet of the requested space. The posted cost is $25 per space per day, with a limit of two parallel or three vertical spaces. For the seven food-truck spaces in the OYD parking lot, the city also limits a permit to three consecutive days. Electricity is available at spaces 2, 4, and 6 for $15 per day plus a $300 damage deposit. Apply through self-service and confirm availability before planning your service day.

If you sell at a fair, market, festival, or event, check city event rules, health department temporary food rules, state sales tax rules, and the host’s vendor packet.

Alcohol is separate. Casper has pages for Liquor Licenses and Liquor Permits. The city says liquor license applications go through review before City Council approval. Also check Wyoming Liquor Division licensing.

Zoning, home businesses, signs, and building work

Zoning comes before opening

Casper says zoning should be verified before opening a business, home occupation, or structure. Use the city Planning and Zoning pages, zoning map tools, and the Casper Municipal Code. Some planning applications have deadlines, so do not build an opening date around a guess.

Home occupations

Casper’s Home Occupations page says a home occupation is a business or commercial use conducted mainly within a dwelling unit and is a permitted use in residential zoning districts when the rules are followed. Only people who live on the premises may work there, the activity must remain secondary to the residence, and it may not occupy more than 25% of the dwelling space, including accessory buildings. The city also bars outside merchandise storage or display and exterior changes tied to the business. Its allowed identification sign must be attached flat to the dwelling, unlit, and no larger than one square foot. Parking, equipment, noise, traffic, and prohibited-use rules still matter.

If you work from home, read BLG’s home occupation permit guide and then check Casper’s exact rules for your address.

Building permits, signs, and contractors

Casper’s permit information page says permits must be obtained before construction of a new building or addition, or remodel, alteration, or repair of an existing structure in the city. Commercial projects often need life-safety plans, engineered drawings, site plans, and Planning/Zoning approval. Permit fees are based on the value of labor and materials, and an issued permit is valid for 180 days. Even when a building permit exception applies, another city approval may still be required.

Contractors should check Casper’s contractor licensing section. The city lists general, subcontractor, plumbing, mechanical, individual, electrical, and reciprocal contractor license types.

Casper’s signage page says commercial sign rules depend on sign type, zone, size, and location. A sign permit is required for commercial signs except qualifying small, private on-site directional signs with no commercial message. Ask before you order, alter, or install a sign.

County, state, and federal steps

Natrona County

If the business address is inside Casper, city zoning is usually the first local land-use check. Natrona County can still matter for health licensing, county records, property issues, or a location outside city limits.

The Natrona County Planning Department says it enforces zoning regulations and issues related planning permits. The county zoning page says zoning regulates the location, construction, alteration, use, and occupancy of structures and land in unincorporated areas. The current county page links to the 2022 Zoning Resolution amended in May 2026. The applications and forms page includes site plans, conditional use permits, zoning certificates, variances, and zone changes.

The Casper-Natrona County Health Department says its Environmental Health Division handles licensing and inspection for food service establishments, mobile units, temporary food events, commercial lodging, campgrounds, daycares, pools, spas, aquatic facilities, and tattoo/body establishments. For temporary food service, the department says applications must be completed in person two weeks before the event; the permit covers one event at one location for no more than 14 days. Establishments preparing potentially hazardous/time-temperature-control-for-safety food must also have a certified manager. Start with the department’s licensing page before buying equipment or promising an opening date.

Wyoming Secretary of State

Many Casper businesses form an LLC, corporation, nonprofit, or limited partnership with the Wyoming Secretary of State. Start with Start a Business or the Secretary of State Business Center. An entity filing is not the same as every license you need. See BLG’s business license vs LLC vs DBA vs seller’s permit guide if the terms are getting mixed together.

The Secretary of State’s fee schedule effective July 1, 2026 lists $100 for domestic LLC Articles of Organization and domestic for-profit corporation Articles of Incorporation, and $150 for a foreign LLC or for-profit corporation Certificate of Authority. For those entities, the annual report license tax is at least $60, or $0.0002 per dollar of Wyoming assets if that amount is higher. Entity type and filing method can change the fee, so use the official schedule rather than a third-party price.

Wyoming uses “trade name” for a DBA-style name. The official trade name application says the trade name must be in use before registration. If the applicant is a business entity, it must be registered and in good standing with the Secretary of State before applying.

The July 2026 state fee schedule lists $100 for a trade-name registration and $50 for renewal. A trade name does not create an LLC or replace a city, tax, health, or professional license.

Wyoming tax, employer, food, and professional rules

If you sell taxable goods, taxable services, lodging, or make certain temporary sales, check the Wyoming Department of Revenue Excise Tax Division. Its sales/use/lodging registration page links to regular vendor, direct pay, occasional sales, and voluntary disclosure applications. The WYIFS page explains the online filing system for sales, use, lodging, and tobacco tax.

Online sellers should not assume marketplace collection solves every issue. Use BLG’s online business license guide for the wider decision path, then confirm Wyoming and Casper rules.

If your business performs work in Wyoming or hires a Wyoming resident, the Wyoming Department of Workforce Services says the business must register so DWS can determine workers’ compensation and unemployment insurance requirements. DWS directs new businesses to complete the joint registration through WYUI and save the registration summary. Register before work begins when required; do not decide for yourself that coverage is optional.

Some occupations need a state professional license. Check Wyoming professional licensing boards and the state licensed occupations directory before advertising regulated work.

The Wyoming Department of Agriculture Consumer Health Services division oversees food safety in Wyoming. Its food safety page says Consumer Health Services inspects licensed food establishments. For a business-type overview, see BLG’s food truck license guide, then verify Casper-specific steps.

Federal steps

Many businesses need an Employer Identification Number. The IRS says you can get an EIN for free directly from the IRS. Start with the official IRS EIN page.

The SBA says federal licenses and permits may apply when a business activity is regulated by a federal agency. Use the SBA licenses and permits page as a starting point.

For beneficial ownership reporting, check the current FinCEN page before relying on old advice. FinCEN issued a final rule on August 11, 2026, effective August 14, that exempts U.S. companies from BOI reporting. Only certain companies formed under foreign law and registered to do business in the United States remain reporting companies; those companies do not report information for U.S. person beneficial owners or company applicants. Use FinCEN’s current BOI page if foreign formation may apply to you.

Costs you can plan for

Do not budget from guesses. Fees can depend on license type, activity, plan review, inspections, and whether you need more than one approval.

Also plan for drawings, inspections, lease changes, grease trap work, fire safety items, signs, insurance, bonds, or professional help when needed.

Real-world examples

A compact compliance checklist

• Write down your business name, owner name, address, website, and exact activity.
• Confirm whether the address is inside Casper city limits or outside in Natrona County.
• Check zoning before signing a lease or buying equipment.
• Compare your activity with Casper’s nine posted Business License categories and its separate health, liquor, mobile-vendor, event, arborist, and contractor pages.
• Create a Casper Citizen Self Service account if the city filing path requires it.
• Ask whether building, fire, occupancy, sign, or inspection steps apply.
• For food, lodging, daycare, pools, tattoo, or body art, check the health department before applying for the city health license.
• For temporary food service, plan for the health department’s stated two-week advance application window.
• Set up Wyoming entity, trade name, tax, employer, and professional license steps that apply.
• Get an EIN directly from the IRS if needed.
• Save approvals, emails, receipts, inspection reports, and renewal reminders.

What to do if this does not work

If you cannot get a clear answer, ask the agency to confirm three things in writing: whether your exact activity is allowed at your exact location, which license or permit name applies, and which office has the next step.

If the city portal does not show your license type, contact the City Clerk or the department named on the license page. If zoning is unclear, ask Planning or Code Enforcement. If food or health rules are unclear, start with the health department and ask whether Wyoming Agriculture issues the license. For hard cases, consider a qualified local attorney, CPA, architect, engineer, insurance agent, or licensing professional.
