Harris County, Texas business license guide
Last updated: August 1, 2026
A Harris County address may be inside Houston, inside another city, or in unincorporated Harris County. That one fact changes which local office handles permits. This guide shows you how to find the right layer before you file, pay, sign a lease, or open.
Bottom line
Texas does not issue one general statewide business license, and Harris County does not act as a one-stop license office for every small business. Most owners need a mix of exact items, such as an assumed name filing, Texas sales tax permit, professional license, food permit, building permit, fire approval, certificate of occupancy, or industry permit.
If the address is inside Houston, city rules may control the site and activity. If it is inside Pasadena, Baytown, Katy, Tomball, Humble, Bellaire, Deer Park, La Porte, or another city, that city may have its own process. If it is outside city limits, Harris County development, fire, floodplain, health, driveway, sign, septic, or water-well rules may apply.
Quick start: do these checks in order
- Write down the exact address and activity. “Online shop,” “restaurant,” “warehouse,” “home salon,” and “food truck” lead to different checks.
- Find the local jurisdiction. Use the Harris County address lookup. A “Houston” mailing address does not always mean the property is inside Houston city limits.
- Check the site before signing a lease. Ask whether your planned use is allowed and whether you need occupancy, building, fire, health, sign, parking, floodplain, or site approval.
- Check the name and ownership structure. A sole proprietor using a trade name usually follows a different assumed-name path than an LLC or corporation.
- Check Texas tax and license rules. Start with the Texas business license guide, then confirm everything with the state agency.
- Check federal rules last. Get an EIN when required and check federal permits if your activity is federally regulated.
First, find the correct local government
Harris County and Houston are not the same licensing layer. Houston is one city inside Harris County. Many addresses use “Houston” in the mailing address even when the property is outside Houston city limits.
Do not rely only on the ZIP code, postal city, landlord, real estate listing, or delivery address. Check the map, then confirm with the office that handles your activity. This matters most for food service, construction, signs, fire review, short-term rentals, street vending, and commercial occupancy.
Before you pay: Ask the agency to confirm that it has authority over your exact address. Harris County Public Health warns food applicants to confirm jurisdiction before paying plan-review fees. The same common-sense check helps with building, fire, and city permits.
For a deeper city-only checklist, use the Houston business license guide. If you are confused about the difference between a license, LLC, DBA, and seller permit, read business license vs. LLC vs. DBA vs. seller’s permit.
Harris County business license layers at a glance
| Government layer | What it may handle | Best first question |
|---|---|---|
| Federal | EIN, federal taxes, alcohol production or importing, firearms, interstate transport, aviation, agriculture, and other federally regulated work | Is my activity regulated by a federal agency? |
| Texas | LLC and corporation filings, assumed names for filing entities, sales tax permits, franchise tax, employer accounts, professional and industry licenses | Which Texas agency regulates what I sell or do? |
| Harris County | Unincorporated assumed names, development permits, floodplain review, certain fire and health approvals, signs, driveways, septic, wells, and business personal property | Is my address outside city limits, and which county division has jurisdiction? |
| Houston or another city | Occupancy, building, fire, food, signs, home-use rules, regulated business licenses, short-term rentals, street vending, and local codes | Is my address inside this city, and is my planned use allowed? |
| Private parties | Lease terms, deed restrictions, HOA rules, insurance, lender rules, marketplace terms, and platform documents | What private rule applies even after government approval? |
Harris County requirements
There is no single county license for every business
Do not search only for a form called “Harris County business license.” The county’s role is usually tied to the business name, location, food or environmental health, construction, fire safety, floodplain, roads, signs, water, sewage, or property reporting.
Harris County assumed name or DBA
Texas calls a DBA an assumed name. The Harris County Clerk assumed-name page says the county files assumed names for unincorporated businesses. This commonly includes sole proprietors and general partnerships that use a business name instead of the owner’s legal name.
Search the Harris County assumed-name records before filing. The county states that a filing term may be from one to ten years. Filing may be done in person or by mail. The Personal Records Department can be reached at 713-274-8686 for current forms, payment rules, and fees.
A DBA is only a name notice. It does not form an LLC, reserve trademark rights, approve a location, issue a tax permit, or replace a professional license.
County development, fire, and site permits
For property outside city limits, start with the Harris County Office of the County Engineer Permits Division. The county permit system covers development and inspections under county regulations and the National Flood Insurance Program.
Use the Harris County Permits A to Z tool to check commercial buildings, commercial site development, tenant work, driveways, signs, floodplain matters, on-site sewage facilities, water wells, fire protection systems, junkyards, salvage yards, fireworks stands, and other project types.
Unincorporated Harris County does not use a full city-style building code for every project. That does not mean there are no rules. Fire code, floodplain, drainage, driveway, septic, water-well, sign, health, and deed-restriction issues can still block or delay a project.
County food permits
The Harris County Public Health food-permit page covers fixed food establishments in its jurisdiction. A business that sells, prepares, serves, or provides food directly to consumers may need plan review, a permit, and inspections before opening.
Inside Houston, use Houston Health instead. Another city may run its own health program or use Harris County Public Health. Confirm the authority before paying.
Business personal property
A license is not the only deadline. The Harris Central Appraisal District business personal property page says renditions are normally due April 15. The report generally reflects taxable business property owned or controlled on January 1, such as inventory, furniture, fixtures, computers, machinery, and equipment.
Do not assume a home business or small online business is automatically exempt. Check the HCAD rules for your facts and ask about an extension before the deadline when needed.
City of Houston requirements
Houston uses activity-based permits, not one blanket license
The Houston Administration and Regulatory Affairs business licensing page lists specific regulated activities. Examples include alcohol-related businesses, alarms, donation boxes, game rooms, certain dealers and resellers, noise and sound permits, street vendors, and short-term rentals. Business Licensing and Enforcement lists 832-394-8803 as its contact number.
For building, occupancy, signs, fire, and many other city permits, start with the Houston Permitting Center.
Certificate of Occupancy
The city says a Houston Certificate of Occupancy must be obtained before a commercial building or individual lease space is occupied, or when the occupancy classification changes. The certificate must match the actual use.
A space approved as an office may not be ready for a restaurant, daycare, salon, assembly use, auto shop, or another use with different code needs. Ask for the existing certificate and verify it with the city before you sign a lease or pay for remodeling.
Houston has no citywide zoning, but it still has location rules
The Houston development regulations page says the city does not have zoning. Houston still regulates subdivision, development plans, parking, setbacks, access, trees, and other site matters. Special land-use limits may also apply near airports and in other areas.
Private restrictions matter too. The city’s deed restriction guidance explains that recorded restrictions can limit business use in a subdivision. A city permit does not erase a lease, deed restriction, or HOA rule.
Houston food businesses
The Houston Health Department food-permit page covers restaurants, groceries, retail bakeries, bars, day-care food service, temporary food establishments, and other fixed food operations inside Houston. The department lists 832-393-5100 for food-permit help.
Houston changed its food rules and fee structure on September 1, 2025 to align with Texas food rules and risk-based state fees. Do not use an old employee-count fee chart or an outdated permit category.
Food trucks and other mobile food vendors changed on July 1, 2026
Beginning July 1, 2026, mobile food vendors in Texas must use the statewide Texas DSHS mobile food vendor license. DSHS assigns Type I, II, or III based on food preparation risk. The current application and pre-licensing inspection fees are:
| DSHS mobile vendor type | Application fee | Pre-licensing inspection fee |
|---|---|---|
| Type I | $309 | Not applicable |
| Type II | $618 | $400 |
| Type III | $876 | $500 |
The DSHS license expires one year after a successful pre-licensing inspection. Mobile vendors must still follow local fire, parking, location, event, property-use, and other rules. For a broader setup checklist, see the food truck license and permit guide.
Houston short-term rentals
Houston requires a city certificate of registration for short-term rentals inside city limits. The current Houston short-term rental page says certificates issued on or before December 31, 2026 expire December 31, 2027. Hosts must provide the city registration number to listing platforms. Starting January 1, 2027, Houston plans to notify platforms to remove listings that lack a certificate.
The online application requires owner or operator details, property information, emergency contact details, listing links, certain hotel occupancy tax information, owner authorization when needed, and human-trafficking awareness training. The city warns that the application cannot be saved and must be completed within one hour after it is started.
Other cities in Harris County
If the property is inside another city, that city may control occupancy, building, fire, signs, food, home occupations, contractor registration, street vending, and local business permits. Do not use Houston forms just because “Houston” appears in the mailing address.
This is especially important in places such as Pasadena, Baytown, Katy, Tomball, Humble, Bellaire, Deer Park, La Porte, South Houston, Jersey Village, and West University Place. Katy also crosses county lines, so confirm both the city and county.
Simple call script
Hello. I plan to operate a [business type] at [full address]. Can you confirm whether this address is inside your city and whether I need a business license, certificate of occupancy, building permit, fire inspection, food permit, sign permit, home occupation approval, or another local permit before I open?
Texas state requirements
LLC, corporation, and other entity filings
Forming an LLC or corporation is separate from getting permission to operate at a location. Use the Texas Secretary of State Business Services page for entity filings, forms, SOSDirect, and registered-agent information.
Assumed names for LLCs and other filing entities
The Texas Secretary of State name filing FAQ says corporations, LLCs, limited partnerships, professional associations, limited liability partnerships, and foreign filing entities file assumed names with the Secretary of State. These filing entities generally do not also file that assumed name with the county clerk.
The state fee is $25 for each assumed name certificate. A certificate may last up to ten years. If important information becomes materially misleading, a new certificate generally must be filed within 60 days. Check the state instructions before filing.
Texas sales and use tax permit
You may need a permit if you sell tangible personal property, rent or lease tangible property, or sell taxable services. The Texas Comptroller sales tax permit FAQ says the permit has no fee, though a security bond may be required in some cases.
The Comptroller says applicants should allow two to three weeks to receive a permit. After approval, permit holders must post the permit, collect tax on taxable sales, file returns on time, pay tax, and keep records. A permit is not transferable to a new owner.
Online sellers should not assume a marketplace handles every duty. Your own website, local pickup, off-platform sales, inventory, services, and business location may create separate rules. See the online store business license guide for common decision points.
Texas franchise tax and employer accounts
Many LLCs, corporations, and other taxable entities must deal with Texas franchise tax reports and information reports. The normal annual due date is May 15, with weekend and holiday adjustments. Check the Comptroller account for the exact filing required, even when no tax is due.
If you hire workers, use the Texas Workforce Commission unemployment tax registration page. TWC says a liable employer must register within ten days of becoming liable.
Professional and industry licenses
Some work needs a state license before you advertise, contract, or perform services. The Texas Department of Licensing and Regulation license list covers many occupations and facilities. Other regulators include the Texas Alcoholic Beverage Commission, Texas Department of State Health Services, Texas Real Estate Commission, Texas Department of Insurance, and Texas Commission on Environmental Quality.
Federal requirements
Employer Identification Number
An EIN is a federal tax ID. The IRS EIN page says you can get one free directly from the IRS. Businesses commonly need an EIN when they hire employees, operate as a partnership or corporation, or meet other federal tax rules.
Do not pay a private company just to submit a normal EIN application unless you knowingly want that service.
Federal licenses and permits
Most ordinary local businesses do not need a federal operating license. Some activities do. The SBA federal licenses and permits guide points to federal regulators for alcohol, aviation, firearms, commercial fishing, mining, nuclear energy, broadcasting, transportation, and other regulated activities.
Common Harris County business situations
| Business setup | Checks that often matter | Do this before spending money |
|---|---|---|
| Home-based consultant or service | City limits, deed restrictions, HOA or lease, customer visits, employees, parking, signs, storage, professional license, DBA | Read Can I run a business from home? and ask the local government about home use. |
| Online seller | Sales tax permit, DBA, home use, inventory storage, business personal property, marketplace and direct-sales duties | Confirm the tax status of every product and service before collecting money. |
| Restaurant, cafe, grocery, or retail bakery | Correct health authority, plan review, food permit, occupancy, fire, grease or wastewater, signs, sales tax | Do not sign a lease until the site can support the intended food use. |
| Home bakery or cottage food seller | Texas cottage food rules, allowed foods, labeling, sales channels, local home-use limits, private restrictions | Use the home bakery license guide, then verify current Texas rules. |
| Food truck, trailer, pushcart, or roadside vendor | DSHS mobile vendor license, pre-licensing inspection, local fire and location rules, commissary or servicing needs, property permission | Choose the correct DSHS type before buying or building the unit. |
| Storefront, office, salon, studio, or warehouse | Allowed use, occupancy certificate, building and fire permits, signs, parking, accessibility, floodplain, trade licenses | Get written confirmation that the site and planned use can be approved. |
| Contractor or mobile service | State trade license, project permits, contractor registration in each city, sales tax on taxable services, vehicle and environmental rules | Separate the company license from the permit needed for each job. |
A home occupation permit is not the same as zoning or occupancy approval. Our home occupation permit explanation shows why local wording matters.
Common mistakes
- Assuming every Harris County address follows Houston rules. Confirm city limits first.
- Calling a DBA a business license. A name filing does not approve the business activity or site.
- Signing a lease before checking occupancy and use. The wrong space can cause major delay and remodeling cost.
- Using an old food permit page. Houston changed food rules in 2025, and Texas moved mobile food vendor licensing to DSHS on July 1, 2026.
- Thinking “Houston has no zoning” means there are no location limits. Development rules, occupancy, building, fire, deed restrictions, and special areas still matter.
- Missing the HCAD rendition deadline. Property reporting is separate from licensing.
- Paying a private filing site without checking the official fee. The Texas sales tax permit and IRS EIN are free from the government.
- Forgetting changes in ownership or address. A new owner, entity, use, or location may require new permits or updates.

Frequently asked questions
Does Harris County require a general business license?
Harris County does not act as a one-stop general license office for every business. The county commonly handles assumed names for unincorporated businesses, development and floodplain permits, certain fire and health matters, signs, driveways, septic, wells, and business personal property. City and Texas requirements may also apply.
Does Houston require a general business license?
Houston does not use one blanket license for every business. It uses activity-based licenses, permits, certificates, and inspections. A business may need a Certificate of Occupancy, food permit, building permit, fire approval, sign permit, street vendor permit, short-term rental registration, or another specific approval.
Where do I file a DBA in Harris County?
Sole proprietors, general partnerships, and other non-filing businesses commonly file an assumed name with the Harris County Clerk when required. LLCs, corporations, limited partnerships, and similar filing entities generally file an assumed name with the Texas Secretary of State instead.
How long does a Harris County assumed name last?
The Harris County Clerk says the term may be from one to ten years from the registration date. File again before the term ends if you will keep using the name. Confirm the current form, fee, and filing method with the Clerk.
Do I need a Certificate of Occupancy in Houston?
A Certificate of Occupancy is required before a commercial building or individual lease space is occupied, or when the occupancy classification changes. The certificate must match the actual use. Confirm the existing certificate before signing a lease.
Who licenses food trucks in Harris County in 2026?
Beginning July 1, 2026, the Texas Department of State Health Services licenses mobile food vendors statewide. Local fire, property-use, parking, event, and location rules still apply. A new operator without a current Texas local mobile food license cannot operate until the DSHS pre-licensing inspection is completed.
Is a Texas sales tax permit free?
Yes. The Texas Comptroller says there is no fee for the sales and use tax permit, although a security bond may be required in some cases. Permit holders must still collect tax when required, file returns, pay tax, and keep records.
Can I run a business from home in Harris County?
Possibly. First confirm whether the home is inside Houston, another city, or unincorporated Harris County. Then check customer visits, employees, parking, signs, deliveries, storage, food preparation, fire safety, deed restrictions, lease terms, and HOA rules.
