Denton County, TX Business License Guide: Cities, DBA, and County Rules

The city or municipal layer: Denton, Frisco, Lewisville, and other cities

If the business address is inside a city or town, the city usually controls many day-to-day local business approvals. This can include certificate of occupancy, zoning, home occupation rules, building permits, fire inspections, signs, food permits, contractor registration, waste hauling, alarm permits, mobile vending, short-term rentals, and special event approvals.

Denton County is a fast-growing DFW county with many overlapping city boundaries. A “Denton County” mailing address does not automatically mean Denton County is the local permitting authority.

City of Denton

The City of Denton has a dedicated permits and licenses section for commercial permits, health and food safety, fire permits, short-term rental registration, contractor registration, right-of-way permits, signs, and other local approvals.

The City of Denton says a certificate of occupancy is required for all new businesses, a change in use, a change in business name, or a change in owner for a single space, tenant, or building. The City’s CO requirements may include a site plan, floor plan, letter of intent, sales tax ID if applicable, and health-related information for a new food establishment.

Start with the City of Denton Permits and Licenses page and the City of Denton Certificate of Occupancy page.

City of Frisco

Frisco spans more than one county. If your business is in the Denton County side of Frisco, do not assume Denton County handles the city-level approvals. Frisco’s own pages cover commercial permits, certificates of occupancy, fire permits, food establishment permits, special events, parking lot sales, public works permits, contractor registration, and the eTRAKiT permitting system.

Frisco says commercial permit workflows can include certificate of occupancy, sign permits, commercial building permits, interior finish-outs, new construction, health packets, fire permits, and related inspections. Frisco also says contractors must register with Building Inspections before doing work in Frisco, and the rule can apply in Frisco’s ETJ when applicable.

Start with Frisco Plans and Permits, Frisco commercial permits, and Frisco contractor registration.

City of Lewisville

Lewisville also has its own building, health, and permitting rules. The City of Lewisville says a certificate of occupancy is required for several commercial situations, including change of ownership, change of tenant, business name change, change of use, new construction, and existing buildings that are enlarged or altered.

Lewisville Building Services manages plan review, permitting, and inspection of private construction projects. Lewisville Health Services conducts food-related health inspections of food service establishments, retail food establishments, temporary food service establishments, mobile food units, schools, and childcare facilities located in Lewisville.

Start with the Lewisville Certificate of Occupancy page, Lewisville Building Permits, and Lewisville Inspections and Permitting.

Denton County also includes or overlaps with other cities and towns. Examples include Flower Mound, The Colony, Little Elm, Carrollton, Highland Village, Roanoke, Corinth, Argyle, Aubrey, Krum, Pilot Point, Sanger, Trophy Club, Lake Dallas, Hickory Creek, Shady Shores, and others.

For any of these cities, check the official city website for:

• business license, certificate of occupancy, or commercial occupancy rules;
• zoning and home occupation standards;
• building, sign, right-of-way, and fire permits;
• health or food permits;
• contractor registration;
• short-term rental rules;
• mobile vendor, solicitor, special event, or parking lot sale permits;
• alarm permits or police permits.

DBA, trade name, and assumed name layer in Denton County

Texas commonly uses the term assumed name. Many people call it a DBA, trade name, or “doing business as” name.

A DBA is not a business license. It does not create an LLC. It does not give tax permission. It does not prove zoning approval. It is mainly a public name notice.

When Denton County Clerk may matter

Denton County has an official Assumed Names (DBAs) page through the County Clerk. The county page explains how to search assumed name records and file an assumed name certificate. The County Clerk’s forms page includes an “Assumed Name Records Certificate of Ownership For Unincorporated Business or Profession.”

The Denton County form states that certificates of ownership are valid only for a period not to exceed 10 years from the date filed in the County Clerk’s Office. Always verify the current form, fee, and filing method on the official county page before filing.

When the Texas Secretary of State may matter instead

For many LLCs, corporations, limited partnerships, limited liability partnerships, and other filing entities, the assumed name filing is handled at the Texas Secretary of State. The Secretary of State’s Form 503 instructions say a domestic or foreign filing entity that regularly conducts business in Texas under a name other than its legal name must file an assumed name certificate with the Secretary of State.

The Secretary of State also notes that a legislative change effective September 1, 2019 eliminated the county-level filing requirement for many filing entities that conduct business under an assumed name. Because this distinction matters, do not assume every business files the DBA in the same place.

Start with the Texas Secretary of State Form 503 instructions and the Texas Secretary of State business filings page.

Name filing checklist

• Know your legal business owner: individual, general partnership, LLC, corporation, nonprofit, LP, LLP, or other entity.
• Know the exact assumed name you want to use.
• Check whether you file with Denton County, the Texas Secretary of State, or both only if an official source says both apply.
• Do not treat a DBA as a trademark search.
• Do not treat a DBA as permission to open at a location.
• Keep proof of the filing with your business records.

Texas state registrations and taxes

Texas does not have one general statewide business license for every business. The Texas Governor’s Business Permit Office says the State of Texas does not require a general license, and that business structure filings with the Secretary of State or assumed name certificates through a county clerk can satisfy the kind of “general business license” requirement that exists in some other states.

That does not remove state tax, entity, employer, and professional licensing duties. Many Denton County businesses still need one or more state-level registrations.

Texas entity registration

If you form an LLC, corporation, limited partnership, nonprofit corporation, or another formal entity, use the Texas Secretary of State. Sole proprietors and some general partnerships may not need to form an entity, but they may still need an assumed name filing, tax permit, zoning approval, or industry permit.

Start with the Texas Secretary of State “Let’s Do Business” page.

Texas sales and use tax permit

The Texas Comptroller says a Texas sales and use tax permit is required for an individual, partnership, corporation, or other legal entity engaged in business in Texas that sells tangible personal property in Texas, leases or rents tangible personal property in Texas, sells taxable services in Texas, or meets the state’s rules for certain out-of-state sellers with Texas revenue.

Examples of businesses that should check sales tax rules include retailers, online sellers, makers, boutiques, contractors selling taxable items, some service providers, food sellers, event vendors, and marketplace sellers. The exact tax result depends on what you sell and how you sell it.

Start with the Comptroller’s Sales and Use Tax Permit FAQ and the Texas Online Tax Registration Application.

Texas employer registration

If you hire employees, check the Texas Workforce Commission for unemployment tax registration and employer obligations. Employer rules can depend on wages, employee type, business structure, and other facts.

Start with Texas Workforce Commission Unemployment Tax Registration.

Professional and industry licenses

Some businesses need a professional or industry license before operating. Examples may include electricians, HVAC contractors, certain health occupations, cosmetology, barbering, massage therapy, towing, vehicle storage facilities, mold assessment/remediation, code enforcement, and many other regulated fields.

Start with the Texas Department of Licensing and Regulation and the state’s Texas occupational and professional licenses page. Some professions are regulated by separate boards, not TDLR, so use the official state directory for your field.

Texas business permit guide

The Texas Governor’s Office points business owners to the Texas Business Licenses and Permits Guide for state-level permits by business type. Use it as a state starting point, but still check your city and Denton County layer.

Zoning, home occupation, building, fire, health, food, and industry permits

Business licensing is not only about a “license.” In Denton County, the approval that stops a business from opening is often zoning, certificate of occupancy, building permit, fire inspection, food permit, septic review, or contractor registration.

Zoning and home occupation rules

Zoning controls whether a certain business activity is allowed at a certain location. A landlord’s lease, a prior tenant’s use, a neighbor’s business, or a property listing does not guarantee zoning approval.

Home-based businesses should be extra careful. Many cities allow some home occupations but restrict customer visits, employees, signage, vehicle storage, noise, outdoor storage, deliveries, food preparation, auto work, retail sales, and hazardous materials. Frisco’s official code enforcement information, for example, says home-based businesses in residential communities have ordinance and zoning requirements. Denton’s development FAQ materials also discuss home occupation limits and prohibited examples.

If your home is outside city limits, still check Denton County Development Services, HOA restrictions, deed restrictions, septic limits, fire access, and any special district rules.

Certificate of occupancy

A certificate of occupancy, often called a CO, is one of the most important city-level approvals for storefronts, offices, warehouses, restaurants, salons, gyms, daycare facilities, repair shops, and other physical locations.

Examples:

• The City of Denton says a CO is required for all new businesses, a change in use, a change in business name, or a change in owner for a single space, tenant, or building.
• Lewisville says a CO is required for change of ownership, change of tenant, business name change, change of use, new construction, and certain enlarged or altered buildings.
• Frisco’s commercial permitting process includes certificates of occupancy and related inspections through its online permitting system.

Before leasing a space, ask whether your proposed use can receive a CO at that address.

Building, remodel, sign, and fire permits

If you build, remodel, change electrical, plumbing, mechanical systems, add signs, install equipment, change occupancy, add outdoor storage, or alter a tenant space, you may need building permits, trade permits, inspections, and sometimes fire review.

Inside a city, contact the city building and fire departments. In unincorporated Denton County, contact Denton County Development Services and the Denton County Fire Marshal. County development and fire permits can be separate from state contractor licensing.

Food, mobile food, and temporary event permits

Food businesses often have more than one layer. A restaurant, bakery, mobile food unit, food truck, temporary event booth, caterer, school food operation, retail food store, or roadside vendor may need state or local health approval, a sales tax permit, a certificate of occupancy, fire review, grease interceptor review, commissary paperwork, and event-specific permission.

Inside the City of Denton, the City’s Health and Food Safety office manages food service industry and public health issues, including health permits and public or semi-public pools within the city. Lewisville Health Services conducts food-related health inspections of food service establishments, retail food establishments, temporary food service establishments, mobile food units, schools, and childcare facilities in Lewisville. Frisco has its own health and food safety and food establishment permit resources.

For state-level food permitting, the Texas Department of State Health Services has a Retail Food Establishments permitting page. DSHS rules and local health authority rules can interact, so always ask which agency has jurisdiction for the exact site and business model.

Mobile vendors and food trucks

Mobile does not mean permit-free. A food truck or mobile vendor may need approval in every city where it operates. A permit from one city may not allow vending in another city or at a private event.

Lewisville, for example, has a mobile vendor page that lists required items before issuing a mobile vendor permit and includes operational restrictions. Denton County also has Fire Marshal guidance for mobile food units. Check the city, event organizer, fire marshal, health authority, and property owner before vending.

Short-term rentals

Short-term rental rules are local. Denton’s permits and licenses page includes short-term rental registration. Frisco’s code enforcement information says STR properties must be registered with the city. Lewisville also lists short-term rentals in its city services. Check the city where the property is located before listing on a platform.

Contractors and trades

Contractors may face multiple layers at once:

• Texas state license or registration for the trade, if required;
• city contractor registration before pulling permits;
• building permits for the job;
• insurance or bond documents required by the city;
• right-of-way, sign, fire, irrigation, backflow, or special permits depending on the work.

Frisco and Denton both publish contractor registration information. Lewisville uses its own permitting system for building permits and contractor registration. A contractor working in several Denton County cities should not assume one registration covers all cities.
