Denver, CO Business License Guide

Denver business changes: April 1, 2026–October 1, 2026

Colorado expanded the Cottage Foods Act effective June 4, 2026. If you prepare food from a Denver home, recheck the current state cottage-food rules instead of relying on an older list of qualifying foods. The 2026 law broadened the state framework and added requirements for some newly covered foods. Denver zoning and any local license or tax duties still apply separately. See Colorado HB26-1033 and the current state guidance before selling.

Denver city steps

1. Check whether Denver licenses your business type

Denver’s Department of Licensing and Consumer Protection handles many business and professional licenses for the City and County of Denver. It does not mean every business receives one universal license. Start with the current license directory and search by the activity you actually perform.

Regulated activities can have separate paths. If your activity is listed, use that exact Denver page. If it is not, continue with zoning, tax, state, and industry checks rather than guessing a license name.

2. Check Denver tax accounts

Denver Treasury administers local business taxes. Depending on what you do, this can include sales and use tax, lodger’s tax, occupational privilege tax, or another Denver tax. Because Denver is a home-rule jurisdiction, a Colorado tax account does not automatically finish the Denver local tax step.

Use Denver Business Tax, the eBiz Tax Center, and the Business Tax FAQs. Employees, short-term lodging, and taxable purchases can create additional Denver tax questions.

3. Treat zoning as an early business step

Denver’s current business guidance says the business use must have a zoning use permit. An existing valid permit may already establish the same use. Confirm the permit on record and apply for a new or change-of-use permit when it does not cover the proposed activity. Zoning also affects parking, signs, outdoor activity, and structures.

Start with the Denver zoning map. Then use the commercial zoning permit page and e-permits. Check this before you sign a lease, remodel, order a sign, or assume the previous tenant’s use covers your business.

4. If you work from home, use the home-occupation path

Denver’s current home business and home occupation page says that if you intend to do business from home and use the home address as the business address, you must obtain a zoning permit for a home occupation. The exact limits depend on the zoning rules for the property, and some properties are still governed by Former Chapter 59 rather than the Denver Zoning Code.

Food production, child care, customer visits, storage, signs, and other activities can trigger added limits or licensing. Colorado law also says an HOA cannot prohibit a home-based business outright, although reasonable HOA rules on parking, noise, landscaping, architectural control, nuisance, and similar impacts may still apply. City rules still apply. For a plain-English overview, see our home occupation permit guide.

5. Check building, occupancy, signs, and fire rules

A business can need more than zoning even when it is moving into an existing space. Denver’s current commercial zoning instructions warn that a change in use or occupancy can trigger building-code review even when no construction is planned. Building work, remodeling, and new signs can require added permits. Start through e-permits.

Fire permits or inspections depend on the operation, materials, equipment, event, or occupancy. Use Denver Fire permits and licensing for the current route instead of assuming one renewal cycle or fee applies to every fire permit.

Colorado and federal steps for a Denver business

Colorado business filings and trade names

Use the Colorado Secretary of State business page or MyBizColorado if you form an LLC, corporation, nonprofit, or other entity. Colorado uses the term trade name for an assumed business name. The Secretary of State says a for-profit business not using its true name, and an individual not using their legal first and last name to conduct business, generally must file a trade name. Use the Colorado trade name FAQ for the current filing path.

Colorado sales tax and Denver local tax

If you sell, rent, or lease taxable tangible personal property, check whether a Colorado sales tax license applies. Then check Denver separately. Colorado Department of Revenue does not administer Denver’s home-rule sales tax account for you. The state and city steps can exist at the same time.

If you want a plain-English comparison, see our guide to a seller’s permit versus a business license.

Hiring workers: do not stop at one employer account

If you hire, check each employer duty separately: withholding, unemployment, new-hire reporting, FAMLI, workers’ compensation, and Denver occupational privilege tax.

• Use the Colorado Department of Revenue withholding account page for state wage withholding.
• Use CDLE’s MyUI Employer system for unemployment insurance employer functions.
• Colorado’s new-hire program directs employers to report required new hires and rehires through the Colorado State Directory of New Hires.
• Check My FAMLI+ Employer for FAMLI registration and reporting that applies to your business.
• Check Colorado’s workers’ compensation insurance requirements.

Professional and industry licenses

A Denver license does not replace a Colorado professional or industry license. Check the Colorado Division of Professions and Occupations or the regulator for your industry.

Federal items

The IRS says many businesses need an EIN because of their structure, employees, or federal tax duties. Use the IRS EIN page directly. The SBA’s licenses and permits guide can route you to federal regulators for federally controlled activities.

FinCEN finalized the current BOI reporting rule in August 2026. U.S.-created companies and U.S. persons remain exempt from BOI reporting under the current rule, while certain foreign entities registered to do business in the United States may still have reporting duties. The August final rule made permanent a practical exemption that had already been introduced in 2025, so this is not a newly created domestic-company exemption during this review period. Check the current FinCEN BOI page if your company could be affected.

Special Denver permits and business types

Food businesses

Food businesses should not stop at a general business setup. Denver routes food operators through licensing, plan review, inspections, food-safety rules, and zoning as the business type requires. Start with Denver’s food license types.

Temporary food booths and event food sales also need the current Denver temporary retail-food route before operating.

Food trucks, trailers, and carts

Denver still requires a Denver mobile retail food license for food trucks, trailers, and carts operating in the city. But the older idea that a mobile unit can never use licensing from another Colorado health department is no longer correct. Colorado food-truck reciprocity took effect January 1, 2026.

Under Denver’s current reciprocal licensing guidance, a valid mobile food license from a Colorado health department can be submitted to Denver at least 14 days before operating and can replace Denver’s mobile plan-review packet. The Denver mobile food license is still required. Fire requirements can remain separate. Also read the mobile retail food guide. For a broader checklist, see our food truck license guide.

Home-prepared food

Colorado’s Cottage Foods Act changed during this review period. The expansion took effect June 4, 2026. If you want to make food at home, check the current state cottage-food category, training or registration that applies to the product, and Denver’s home-occupation zoning rules. A state cottage-food allowance does not erase Denver zoning or tax duties.

Short-term rentals and residential rentals

Denver requires a short-term rental license for rentals of less than 30 consecutive days, and the licensed short-term rental must be the host’s primary residence. Use Denver’s short-term rental laws and rules before listing the property. Denver also has a separate residential rental property license path for residential rentals of 30 days or more.

Contractors

Denver contractor licensing is separate from ordinary business setup. Denver’s contractor licensing page explains the current license and supervisor-certificate path. State electrical or plumbing credentials can also matter depending on the work.

Alcohol and other regulated activities

For alcohol or another specially regulated activity, use the Denver license directory and the applicable state regulator. One level of approval does not replace the other.

Costs you can plan for

There is no single Denver fee to budget for. Confirm each current application, license, inspection, renewal, zoning, or state charge on the exact official page.

What does this mean for me?

Ask which approvals match your activity and address. Start with zoning use, then Denver licensing and taxes, then the Colorado and federal layers that apply. Check this path before spending money on a lease, build-out, equipment, signs, or advertising.

Real-world examples

What to do if this does not work

If you cannot find your activity, search the Denver license directory with related terms and describe exactly what customers pay you to do. Address and allowed-use questions go to Community Planning and Development; Denver tax questions go to Treasury. If you operate outside Denver, check that local jurisdiction too.

A compact compliance checklist

• Pick the exact business activity and public business name.
• Confirm the physical location is inside the City and County of Denver.
• Check whether you need a Colorado entity filing or trade name.
• Check whether the Denver address already has the right zoning use permit or needs a new/change-of-use permit before spending money.
• If working from home and using the home address as the business address, check the home-occupation zoning permit.
• Check Denver’s license directory for the exact activity.
• Check Denver Treasury and eBiz for city tax accounts.
• Check Colorado Department of Revenue for state sales tax or wage withholding.
• If hiring, check MyUI Employer, new-hire reporting, FAMLI, workers’ compensation, and Denver employer taxes.
• Use the exact local and state path for food, fire, contractors, rentals, tobacco, liquor, marijuana, child care, professional work, or another regulated activity when it fits your business.
• Get an EIN from the IRS if your structure, employees, or federal tax duties require one.
• Save licenses, tax letters, zoning approvals, inspections, renewals, and agency messages.
