Dallas County, Texas business licensing guide
Accuracy date: May 18, 2026 · Last updated: May 18, 2026 · Next review date: September 18, 2026
Opening a business in Dallas County can be confusing because “Dallas County” is not the same thing as “City of Dallas.” A storefront in Dallas, Garland, Irving, Grand Prairie, Mesquite, Richardson, Carrollton, Farmers Branch, DeSoto, Duncanville, Lancaster, Cedar Hill, University Park, Highland Park, Sachse, Coppell, Rowlett, or another municipality may have city rules that are separate from county and state rules.
This guide explains the county layer in plain English. It does not replace the City of Dallas guide, a suburb’s local rules, or Texas state agency instructions. Use it to decide which office to check before you file, pay, sign a lease, sell food, hire workers, or operate under a trade name.
Bottom line
Dallas County does not appear to issue one countywide general business license for every business. In Texas, there is no statewide general business license either. Most Dallas County businesses need to check a mix of:
- City or town rules, if the business address is inside a municipality.
- Dallas County Clerk assumed name rules, especially for sole proprietors and other non-Secretary-of-State filing businesses using a DBA.
- Dallas County unincorporated-area rules, if the business location is outside city limits.
- Dallas County Health and Human Services rules, especially for mobile food units and certain public health inspections.
- Texas state tax, entity, employer, and professional licensing rules.
- Federal rules, if the business is in a federally regulated industry or needs an EIN.
The most important first step is the address. A business inside the City of Dallas usually deals with City of Dallas zoning, certificate of occupancy, building permits, food permits, short-term rental rules, and certain city licenses. A business inside another Dallas County municipality must check that municipality instead. A business in unincorporated Dallas County must check Dallas County’s Department of Unincorporated Area Services and, when relevant, the Dallas County Fire Marshal and Dallas County Health and Human Services.
Start here: city vs. county address check
Before you ask “Do I need a Dallas County business license?” ask this first:
Is the business location inside a city, or is it in unincorporated Dallas County?
This matters because Dallas County’s own zoning page says Texas cities, not counties, have zoning authority. Dallas County also explains that its unincorporated area is land not located within a city and is less than ten percent of the county. That means many businesses in Dallas County are actually under city rules for zoning, occupancy, building, fire, signs, local licenses, and some health permits.
Practical address-check steps
- Search the exact business address. Use the Dallas Central Appraisal District property tools, the City of Dallas zoning/map tools if the address may be in Dallas, or the relevant suburb’s address tools.
- Look for the city or taxing jurisdiction. A Dallas County mailing address does not always mean City of Dallas. A ZIP code can cross city lines.
- If the address is inside a city, contact that city first. Ask about zoning, certificate of occupancy, business-specific permits, signs, fire inspection, health permits, and home occupation rules.
- If the address is outside city limits, contact Dallas County DUAS. Ask whether the site is in unincorporated Dallas County and whether development, floodplain, fire, septic, outdoor-business, or other county rules apply.
- Then check the state layer. Texas sales tax, entity filings, employer registration, and professional licenses are separate from city and county permissions.
Tip: Do not rely only on a postal city, ZIP code, Google Maps label, or landlord statement. For licensing and permits, the official jurisdiction matters.
Dallas County business license and permit layer
Dallas County’s role is mostly not a universal business license role. The county layer is more specific. It can involve assumed name records, unincorporated-area development permits, fire review, certain outdoor-business rules, mobile food health inspections, property tax records, and other narrow county functions.
Does Dallas County have a general business license?
Based on the official sources reviewed for this guide, Dallas County does not appear to issue a single countywide general business license that every business must get before opening. Texas state sources also say Texas does not require a general business license.
That does not mean you can ignore the county. It means the county item may be called something else, such as an assumed name certificate, development permit, fire permit, mobile food unit inspection, outdoor business regulation, septic approval, or public health permit.
When Dallas County matters
| Issue | Dallas County role | What to check |
|---|---|---|
| DBA / assumed name | County Clerk records certain assumed names, especially for sole proprietors and other non-filing businesses. | Dallas County Clerk assumed name procedures and Texas Secretary of State rules for filing entities. |
| Unincorporated location | County DUAS handles development, floodplain, permits, subdivisions, addressing, outdoor-business rules, and related reviews. | Dallas County Department of Unincorporated Area Services. |
| Zoning | Dallas County says Texas counties do not have authority to adopt zoning ordinances. Cities handle zoning inside city limits. | City zoning office if inside a city; DUAS for county regulations if outside city limits. |
| Building and fire in unincorporated areas | County development review may involve DUAS and the Dallas County Fire Marshal. | DUAS, Fire Marshal, and any applicable road, health, septic, or floodplain review. |
| Mobile food units | Dallas County Health and Human Services handles mobile food unit health and safety inspections, but this does not replace city or unincorporated-area rules. | DCHHS Environmental Health plus each city or unincorporated-area authority where the unit operates. |
| Business personal property | Property tax and appraisal records are not business licenses, but businesses may need to understand appraisal and tax accounts. | Dallas Central Appraisal District and Dallas County Tax Office. |
Unincorporated Dallas County
If your business site is outside city limits, Dallas County’s unincorporated-area rules become important. Dallas County says development activities in unincorporated areas, including residential or non-residential construction, installation, grading, filling, floodplain work, on-site sewerage facility work, sand and gravel operations, and similar development activities, need a permit.
Dallas County also says it regulates issues such as floodplain development, subdivisions, septic tanks, neighborhood nuisance conditions, construction and inspection of certain residential structures, construction of commercial buildings, communication facility structures, and certain outdoor businesses in the unincorporated area.
For a storefront, shop, warehouse, contractor yard, food operation, outdoor storage business, recycling business, salvage yard, or similar use in unincorporated Dallas County, contact DUAS before you lease or buy the site.
Outdoor businesses in unincorporated areas
Dallas County has specific outdoor-business regulations for certain businesses in unincorporated areas. These may include automotive wrecking and salvage yards, demolition businesses that store salvaged building materials, junkyards, outdoor resale businesses, and recycling businesses.
These are not “normal business licenses” in the simple sense. They are land-use and public-safety rules that may affect where and how the business can operate.
County fire layer
The Dallas County Fire Marshal’s building permit page says that construction and land development in unincorporated areas goes through a permit and inspection process managed by DUAS in partnership with the Fire Marshal and other departments.
If your business will build, remodel, install fire-related systems, use hazardous materials, operate a special event, or open in an unincorporated location, ask whether Fire Marshal review or inspection is required. If the business is inside a city, ask that city’s fire department or fire marshal instead.
City or municipal layer
Most business locations in Dallas County are inside a city. If the business address is inside city limits, the city often controls the local approval path.
That may include:
- zoning approval;
- home occupation rules;
- certificate of occupancy;
- building permits;
- fire review or fire inspection;
- sign permits;
- food establishment permits;
- mobile vendor, solicitor, or peddler rules;
- short-term rental registration or hotel occupancy tax rules;
- special business licenses for certain regulated activities.
City of Dallas
If the business is inside the City of Dallas, start with the City of Dallas Planning and Development, zoning, certificate of occupancy, and permit tools. The City of Dallas certificate of occupancy page says a person generally may not use or change the use of a building, part of a building, or land without a Certificate of Occupancy, except for single-family and duplex uses. A new CO may be needed for first use, change of use, change of tenant, or a change in floor area.
The City of Dallas also lists certain special licenses through Special Collections. Examples include amusement centers, beer or liquor-related city licenses, billiard halls, coin-operated machines, dance halls, precious metal vendors, and sexually oriented businesses. These are business-type-specific licenses, not a universal license for every business.

Dallas County suburbs and towns
If the business is in a Dallas County suburb, check that city directly. Do not assume City of Dallas rules apply to Garland, Irving, Grand Prairie, Mesquite, Richardson, Carrollton, Farmers Branch, DeSoto, Duncanville, Cedar Hill, Lancaster, Coppell, Sachse, Rowlett, University Park, Highland Park, or another municipality.
Many cities have their own development services, building inspection, fire marshal, health, code compliance, sign, short-term rental, and special event rules. Some cities also contract with Dallas County or another agency for certain inspections. The only safe path is to confirm with the city that controls the address.
Warning: A Dallas County assumed name filing does not approve your location, zoning, food permit, CO, fire inspection, sales tax registration, or professional license. It only addresses the public name record layer.
DBA and assumed name layer
In Texas, a DBA is usually called an assumed name. It lets the public see who is behind a business name. It does not create an LLC, protect the name like a trademark, approve zoning, or act as a sales tax permit.
Dallas County Clerk assumed names
The Dallas County Clerk handles assumed name filings for certain businesses. The county’s assumed name page says assumed name applications may be completed online or in office, and that a business name can be filed or recorded with the Dallas County Clerk by coming into the office or following the mail-in instructions.
For many small operators, this county layer matters when a sole proprietor, sole practitioner, general partnership, joint venture, trust, estate, or certain other non-Secretary-of-State filing business uses a name that is not the owner’s legal name.
Texas Secretary of State assumed names for filing entities
If the business is an LLC, corporation, limited partnership, limited liability partnership, or other filing entity, check the Texas Secretary of State assumed name rules. The Secretary of State’s Form 503 instructions say those filing entities must file an assumed name certificate with the Secretary of State if they regularly conduct business or render a professional service in Texas under a name different from their legal entity name.
The Secretary of State also explains that a 2019 law change eliminated the county-level filing requirement for these filing entities when they conduct business under an assumed name. That is why it is important to know whether your business is a sole proprietorship/general partnership type or an LLC/corporation/other filing entity.
DBA does not replace these items
- LLC or corporation formation;
- Texas sales and use tax permit;
- city zoning approval;
- certificate of occupancy;
- food establishment or mobile food permit;
- building or fire permits;
- professional or occupational license;
- federal EIN or federal permit.
Texas state registrations and taxes
The Texas layer is separate from Dallas County and city rules. You may need state filings even if the county does not require a general business license.
No general Texas business license
The Office of the Texas Governor says a general business license is not required in Texas. The same state source says you still need to determine whether your business activity requires licenses, permits, certifications, registrations, or authorizations at the federal, state, and local level.
The Texas Business Permit Office also says many specific business activities require permits or licenses and tells businesses to check local city and county governments.
Entity formation
If you form an LLC, corporation, limited partnership, or other Texas filing entity, you generally work through the Texas Secretary of State. Sole proprietorships and some general partnerships do not form through the Secretary of State just because they start doing business, but they may still need an assumed name filing, tax permit, local approval, or industry license.
Texas sales and use tax permit
If you sell taxable goods or taxable services, check the Texas Comptroller. The Comptroller’s online tax registration system is the state source for sales tax permit registration and other tax accounts.
A Texas sales and use tax permit is not the same as a city business license, county assumed name, or certificate of occupancy. It is a state tax permit.
The Comptroller’s sales tax FAQ also warns that when you apply for a sales and use tax permit, the Comptroller may inform you about other taxes, licenses, or fees, but it remains the business owner’s responsibility to determine what federal, state, or local taxes, licenses, or fees apply.
Employer registration
If you hire employees, check federal employer rules and Texas Workforce Commission requirements. The Texas Workforce Commission says employers must register with TWC within 10 days of becoming liable under the Texas Unemployment Compensation Act.
Professional and occupational licenses
Some businesses need a state professional or occupational license. The Texas Department of Licensing and Regulation licenses and regulates many occupations, businesses, facilities, and equipment. Depending on the work, another state board may control the license instead.
Examples to verify include electrical work, air conditioning and refrigeration work, barbering, cosmetology, towing, massage therapy, mold assessment or remediation, water well work, and other regulated activities. Do not assume that a city or county filing gives permission to perform state-regulated work.

Zoning, home occupation, building/fire, health, food, and industry permits
Business “licensing” in Dallas County is often really a stack of approvals. Your stack depends on the location and business activity.
Zoning and land use
If you are inside a city, check that city’s zoning rules. Dallas County’s official zoning page says only cities, not counties, have authority to adopt zoning ordinances in Texas.
If you are outside city limits, Dallas County does not call it zoning, but county regulations can still matter. The county may regulate development in floodplains, subdivisions, septic tanks, nuisance conditions, residential construction inspections, certain commercial buildings, communication structures, and certain outdoor businesses.
Home-based businesses
A home-based business inside the City of Dallas or another municipality should check that city’s home occupation rules before advertising, seeing customers, storing inventory, adding signs, creating traffic, or using employees at the home.
A home business in unincorporated Dallas County may not face city zoning, but that does not mean there are no rules. You may still need to check county development rules, septic or health rules, nuisance rules, fire rules, deed restrictions, lease terms, HOA rules, tax permits, assumed name filings, and professional licenses.
Storefronts, offices, warehouses, and tenant spaces
For a storefront, office, warehouse, salon, restaurant, daycare, repair shop, gym, studio, or similar physical location, check local approval before signing a lease. Important questions include:
- Is the use allowed at this address?
- Is a certificate of occupancy required?
- Does a change of tenant or change of use require a new CO?
- Are building permits needed for remodeling, signs, plumbing, electrical, grease traps, ventilation, or accessibility changes?
- Is fire review or inspection needed?
- Are food, pool, childcare, alcohol, massage, salon, or other special permits needed?
Food businesses
Food businesses can have several layers. For a fixed food establishment inside the City of Dallas, the City of Dallas Consumer Health page says food establishment permits are required for restaurants, bars, grocery stores, schools, and other retail food establishments.
For a fixed food business in another Dallas County city, check that city’s health or environmental health rules. Some cities handle food permits directly, and some may rely on Dallas County or another public health arrangement.
For mobile food units, Dallas County Health and Human Services says a Dallas County MFU permit is for health and safety inspection only. The county also says it does not exempt the mobile unit from local municipal laws or unincorporated-area zoning, parking, fire, or other regulations.
Dallas County also warns that effective July 1, 2026, mobile food unit operators may be required to obtain a permit issued by the Texas Department of State Health Services to continue operating in Texas, and local permits issued before that date may no longer be valid after July 1, 2026. Because this change is time-sensitive, mobile food vendors should check Dallas County Health and Human Services and Texas DSHS before paying fees or booking events.
Building and fire permits
Building and fire rules depend on the address. If the project is inside a city, the city’s building and fire departments usually control. If the project is in unincorporated Dallas County, DUAS and the Dallas County Fire Marshal may be part of the review.
Do not begin construction, remodeling, installation, or a change of use until the proper local building and fire office confirms the permit path.
Short-term rentals
Short-term rental hosts should check the city where the property is located. The City of Dallas has short-term rental and hotel occupancy tax resources. Dallas city rules are not the same as rules in every Dallas County suburb.
If the property is outside city limits, check Dallas County and Texas tax rules, and also check deed restrictions, HOA rules, insurance, and platform requirements.
Contractors and trades
Contractors should separate three layers:
- State license layer: Some trades require a state license or registration.
- Local permit layer: Building, electrical, mechanical, plumbing, sign, and fire permits depend on the job address.
- Business location layer: Your office, yard, warehouse, home office, or storage site may need zoning or county review.
A contractor working throughout Dallas County may need to deal with several cities, not just one county office.
Common Dallas County business situations
Online seller from home
An online seller may still need a Texas sales and use tax permit if selling taxable goods or services. If the seller uses a trade name, they may need an assumed name filing. If the business operates from a home inside a city, home occupation rules may apply. If inventory pickup, customer visits, employees, signage, or deliveries change the property use, local rules become more important.
Freelancer or consultant
A freelancer may not need a county business license just because they live in Dallas County. But they should check assumed name rules if using a DBA, city home occupation rules if working from home, Texas tax rules if selling taxable services, and professional licensing rules if their work is regulated.
Restaurant or cafe
A restaurant or cafe should check zoning, certificate of occupancy, building permits, food establishment permits, fire inspection, grease trap or plumbing rules, signs, alcohol rules if relevant, and Texas sales tax. The city often controls the local path if the location is inside a city.
Food truck or mobile food unit
A food truck should check Dallas County Health and Human Services, Texas DSHS updates, the fire department for each operating location, city parking or vending rules, commissary rules, event rules, and sales tax. A Dallas County health inspection does not by itself approve every city location.
Storefront retailer
A retailer should verify the address, zoning, certificate of occupancy, building or sign permits, sales tax permit, assumed name, alarm permits if relevant, and any special city license for the product or activity.
Salon, barber, massage, tattoo, or personal service business
Personal service businesses often have state licensing, local certificate of occupancy, building, sanitation, fire, and city rules. Do not rely on a lease or DBA filing as proof that the site is approved.
Auto, salvage, recycling, outdoor resale, or storage business
These businesses need careful address review. If inside a city, check city zoning and permits. If in unincorporated Dallas County, check DUAS outdoor-business regulations, development permits, fire rules, and any environmental or state permits.
What to ask before filing or paying
Before you pay for an application, sign a lease, buy equipment, or advertise the business, contact the right agency with a short summary of your plan.

Common mistakes
- Assuming Dallas County means City of Dallas. Dallas County contains many municipalities. The correct city matters.
- Asking only for a “business license.” The real requirement may be called a certificate of occupancy, assumed name, food permit, sales tax permit, development permit, or special license.
- Filing a DBA and thinking the business is approved. A DBA is a name record. It does not approve zoning, taxes, food, fire, or building use.
- Signing a lease before checking zoning and CO rules. A landlord may not know whether your exact use is allowed.
- Ignoring unincorporated-area permits. Outside city limits, Dallas County DUAS and the Fire Marshal may still matter.
- Thinking mobile food approval is one-and-done. A county health inspection does not replace city parking, fire, event, or vending rules.
- Forgetting state taxes and licenses. Texas sales tax, employer registration, and professional licensing can apply even when no county general license exists.
- Using old fee or permit information. Fees, portals, forms, and permit paths change. Always verify with the official source before paying.

FAQ
Does Dallas County have a general business license?
Dallas County does not appear to issue one countywide general business license for every business. The county layer is usually more specific, such as assumed name filings, unincorporated-area development permits, fire review, mobile food health inspections, outdoor-business regulations, or property tax records.
If my business is in the City of Dallas, do I use Dallas County or the city?
Use both, but for different things. The City of Dallas usually controls zoning, certificate of occupancy, city building permits, city food permits, city fire review, signs, short-term rental rules, and certain special city licenses. Dallas County may still matter for assumed names, mobile food unit inspections, county records, or other county-specific issues.
If my business is in a Dallas County suburb, do City of Dallas rules apply?
Usually no. A business in Garland, Irving, Grand Prairie, Mesquite, Richardson, Carrollton, Farmers Branch, DeSoto, Duncanville, Cedar Hill, Lancaster, or another municipality should check that city’s rules. City of Dallas rules normally apply only inside City of Dallas limits.
What if my business is outside city limits?
Contact Dallas County Department of Unincorporated Area Services. Ask whether the site is in unincorporated Dallas County and whether development, floodplain, septic, building, fire, outdoor-business, addressing, or other county rules apply.
Where do I file a DBA in Dallas County?
It depends on the business structure. Many sole proprietors and other non-filing businesses using an assumed name check with the Dallas County Clerk. LLCs, corporations, limited partnerships, limited liability partnerships, and other filing entities using an assumed name generally check the Texas Secretary of State’s Form 503 process.
Is a Texas sales tax permit the same as a business license?
No. A Texas sales and use tax permit is a state tax permit from the Texas Comptroller. It does not replace a city certificate of occupancy, city permit, county assumed name filing, food permit, fire approval, or professional license.
Do food trucks need Dallas County approval?
Mobile food units should check Dallas County Health and Human Services and Texas DSHS updates. Dallas County says its MFU permit is for health and safety inspection only and does not exempt the operator from city, fire, zoning, parking, or other local rules.
Does Dallas County zoning apply to my business?
Dallas County says Texas cities, not counties, have authority to adopt zoning ordinances. If your business is inside a city, check that city’s zoning office. If it is outside city limits, Dallas County may still have unincorporated-area regulations for development, floodplain, septic, outdoor businesses, commercial buildings, and related issues.
Can I run a home business in Dallas County?
Maybe, but the rules depend on the exact address and activity. Inside a city, check home occupation and zoning rules. Outside city limits, check Dallas County unincorporated-area rules, health and fire issues, deed restrictions, HOA rules, lease terms, Texas tax permits, assumed name rules, and any professional license requirements.
