Tarrant County, TX Business License Guide: Fort Worth, Arlington, and County Rules

Tarrant County business changes: May 1–October 2, 2026

• Mobile food licensing moved to the state on July 1, 2026. Texas DSHS now licenses mobile food vendors statewide. Tarrant County says its former mobile-unit permits had to be reissued through DSHS, while local zoning, fire, location, event, and other local rules can still apply.
• Tarrant County Engineering fees changed effective October 1, 2026. The Commissioners Court approved new or increased Engineering Services fees for development review, platting, inspections, and several permits. Use the current county fee schedule instead of an older amount.
• Texas launched SOSPortal on September 29, 2026. The Secretary of State says SOSPortal replaced SOSDirect and SOSUpload for business filings, orders, and searches. The old article’s SOSDirect route is therefore no longer the current filing path.
• Fort Worth adopted a new electrical-code edition during this review period. The city’s current permits page says the 2026 National Electrical Code became effective September 1, 2026. This matters mainly when electrical work or electrical permits are part of a project.

Tarrant County business license, tax, and permit layer

For most ordinary businesses, the county layer is tied to a specific function rather than one basic license.

County assumed-name records

The Tarrant County Clerk assumed-name page is the county route for many sole proprietors and general partnerships using a name different from the owner’s legal name. The county itself warns that an assumed-name certificate is not a business license. Filing a DBA does not give zoning, health, tax, occupancy, or operating approval.

County public-health jurisdiction

Tarrant County Public Health regulates food establishments in unincorporated Tarrant County and in the municipalities on its Consumer Health Contract Cities list. The current list specifically says the county does not regulate food establishments in Arlington, Burleson, Euless, Fort Worth, Grand Prairie, Mansfield, or North Richland Hills. Those cities need their own health route or another applicable authority.

For mobile food, use the newer statewide rule. Since July 1, 2026, DSHS is the licensing authority for mobile food vendors. Tarrant County may perform an inspection when assigned under an agreement, but its current inspections page says mobile vendors should apply through DSHS rather than seek a new county mobile-unit permit.

Unincorporated development, ETJ, and fire rules

Tarrant County Engineering says the county does not have authority to impose zoning in unincorporated territory and does not issue normal building permits or certificates of occupancy. Development there can still be subject to county subdivision, drainage, roadway, stormwater, platting, and engineering standards. In many unincorporated areas, a city ETJ can add a municipal plat-review step.

The Tarrant County Fire Marshal separately administers fire-code requirements in unincorporated areas. Covered commercial buildings, public-access buildings, multifamily construction, fire systems, and certain operational activities can require county fire review or permits even though the county does not issue a normal building permit.

Road, right-of-way, floodplain, septic, and development permits

The county’s Engineering permitting page routes permits involving county-maintained roads, access points, culverts, floodplain development, right-of-way encroachments, utilities, cell towers, building moves, and mobile-home rental communities. The separate Engineering fee schedule was revised effective October 1, 2026. Check that schedule before filing instead of relying on an old fee.

Fort Worth, Arlington, and other city rules

Inside an incorporated municipality, the city normally controls zoning and occupancy. Separate county functions may still apply, but county filings do not substitute for city approval.

Fort Worth businesses

Fort Worth’s current business guide says a general business license is not required in Texas and directs local businesses instead through registration, zoning, occupancy, and activity-specific permits. Its Certificate of Occupancy page says occupied buildings generally need a CO, and a different business use can trigger a new occupancy/change-of-use process. Permit applications use Accela Citizen Access.

For home businesses, Fort Worth now has a useful state-law update page explaining the 2025 Texas home-business law. For mobile food, the city says vendors now obtain the DSHS mobile-food license rather than a Fort Worth health permit, while other city rules can still apply.

See BLG’s Fort Worth, TX business license guide for the city-specific path.

Arlington businesses

Arlington uses separate permit and registration paths. Arlington Permits and Planning and Development Services cover items such as certificates of occupancy, commercial permits, fire permits, signs, zoning, and business-related registrations. Arlington Health Services separately handles food establishments, temporary food, catering, child care, pools, hotels, and other health programs through the same online permitting environment.

Arlington’s current guidance says a tenant space may not be operated until a required Certificate of Occupancy is issued. For food businesses, Arlington Health Services says a new or existing food business needs the applicable CO before the health operating permit path.

See BLG’s Arlington, TX business license guide for the city-specific path.

Other Tarrant County municipalities

Do not copy Fort Worth or Arlington rules to another municipality. Each city can have different zoning, occupancy, vendor, fire, home-business, and rental rules.

DBA and assumed-name filings in Tarrant County

Texas commonly uses the term assumed name for a DBA. The correct filing office depends mainly on the business structure.

Tarrant County notes that, since September 1, 2019, filing entities such as corporations, LLCs, LLPs, limited partnerships, and foreign filing entities file assumed-name certificates with the Secretary of State rather than filing the entity’s assumed name in each county. That is an older rule, not a new 2026 change, but it remains important because the old county route is still easy to misunderstand.

For an eligible sole proprietor or general partnership, the county filing can still apply inside an incorporated city. It remains separate from city operating approvals.

Texas state registrations and taxes

Entity filing and SOSPortal

Texas LLCs, corporations, limited partnerships, and other filing entities use the Texas Secretary of State. On September 29, 2026, the state launched SOSPortal to replace SOSDirect and SOSUpload. Use the Secretary of State Business Services page for the current filing/search route and service notices. On this review date, that page also carries a maintenance notice for SOSPortal, so the official page is the safest place to check current availability rather than using a saved legacy SOSDirect bookmark.

Texas sales and use tax

If you sell or lease taxable goods or provide taxable services, check the Texas Online Tax Registration Application. The Comptroller says the online application covers sales and use tax and certain other tax accounts. Do not assume an online business is exempt just because customers order through a website or marketplace; the answer depends on what you sell and how the sale is made.

Franchise tax and public-information filings

Many Texas filing entities fall under the franchise-tax system even when no tax is due. Use the Comptroller franchise-tax page for current reporting rules.

If you hire employees

Employers should check the Texas Workforce Commission for unemployment-tax registration and wage reporting. TWC announced that its new Texas Unemployment System, TxUS, would replace UTR and UTS, with a go-live by or on June 1, 2026. Because system access can change during migrations, enter through TWC’s current unemployment-tax registration page rather than relying on an old saved login.

New-hire reporting is a separate requirement. The Texas Office of the Attorney General says employers must report new hires and rehires within 20 calendar days and provides an official online reporting route.

Professional and industry licensing

A city or county approval does not replace a required state professional or trade license. Use Texas.gov’s license directory and the TDLR programs list to find the correct state agency.

Zoning, home business, building, fire, food, and industry permits

Zoning, occupancy, and building work

Inside a city, verify the proposed use before signing a lease or remodeling; a prior tenant’s approval does not automatically cover a different use. In unincorporated Tarrant County there is no county zoning or ordinary county CO, but platting, drainage, road, floodplain, septic, fire-code, private restrictions, and state rules can still matter.

Home-based businesses: Texas law changed the city layer

Texas Local Government Code Section 229.902 took effect June 12, 2025, before this article’s current review window. It creates a protected category called a no-impact home-based business. The statute generally defines that category by limits tied to occupancy, on-street parking and traffic, street visibility, and noise.

If a business meets that definition, a municipality may not prohibit it or require a license, permit, or other approval merely to operate it. Cities can still enforce specified health, safety, traffic, waste, pollution, noise, and residential-compatibility rules. HOA/deed restrictions and short-term-rental regulation are not erased.

Food establishments and mobile food

For a fixed restaurant, bakery, caterer, grocery, or food-preparation business, first identify the health jurisdiction. Tarrant County Public Health covers unincorporated areas and its listed contract cities, while Arlington, Fort Worth, and several other cities are outside that county food program.

Mobile food is now different. Since July 1, 2026, the Texas Department of State Health Services mobile-food program handles the statewide mobile-food-vendor license. A DSHS license does not erase valid local zoning, fire, location, right-of-way, event, or other non-health requirements.

Short-term rentals, alcohol, contractors, and other regulated work

Short-term rentals are city-specific where regulated. Alcohol licensing runs primarily through the Texas Alcoholic Beverage Commission, with local rules sometimes added. Contractors and trades may need a state license, city registration, and job-specific permits; Fort Worth, for example, requires contractor registration for many firms pulling covered trade or building permits.
